+
+## Acquisition decisions
+
+| Platform | Stable read path | Notes |
+| --- | --- | --- |
+| note | `https://note.com/{user}/rss` plus existing compatibility fetcher | Official help documents RSS. Standard RSS includes excerpts; full RSS is note pro / custom-domain limited. Existing unofficial JSON endpoints stay compatibility-only. |
+| Zenn | `https://zenn.dev/{user}/feed?all=1` | Zenn documents user RSS and `all=1`. Unofficial JSON endpoints exist in the wild but are not the primary contract. |
+| Qiita | Qiita API v2 `GET /api/v2/users/:user_id/items` | Official API returns public item metadata and Markdown body. Unauthenticated clients are rate-limited to 60 requests/hour/IP. |
+| Cor.inc blog | `https://cor-jp.com/rss.xml`, `src/content/blog/ja/*.md` in `corsweb2024`, and semantic HTML fallback | The repo is the best source for exact frontmatter and Markdown body format. Article generation should target `src/content/blog/ja/{slug}.md` first; multilingual expansion can happen later through the existing site pipeline. |
+
+## Initial persona and format split
+
+| Persona | Default format | Practical voice hints |
+| --- | --- | --- |
+| `terisuke` | `note_article` | First person `僕` / `私`; note is for broad-reader technical experiments and reflections; Cor.inc blog is for company technical knowledge reports, implementation decisions, and employee-facing vision sharing. |
+| `cloudia` | `zenn_article` | First person `クラウディア` / `うち`; light Hakata-ben flavour; technical tutorial voice; exclamation-rich titles; code and step-by-step guidance. |
+
+| OutputFormat | Minimum validator |
+| --- | --- |
+| `note_article` | Starts with `# `, no YAML frontmatter, no platform-specific extended Markdown. Plain code fences are allowed only when needed. |
+| `markdown_blog` | Cor.inc Astro blog frontmatter is required: `title`, `description`, `pubDate`, `author`, `category`, `tags`, `lang`, `featured`. Body starts with `# ` or `## `. |
+| `zenn_article` | YAML frontmatter with `title`, `emoji`, `type`, `topics`, `published`; `type` is `tech` or `idea`. |
+| `qiita_article` | YAML frontmatter with `title` and `tags`; code fences allowed. |
+| `homepage_section` | HTML output containing `<section>`, `<h2>`, and `<p>`. |
+
+## Editor notation split
+
+The output mode should also choose notation, not just prose.
+
+| Format | Practical notation policy |
+| --- | --- |
+| note | Keep to the subset that paste-converts reliably in the note editor: `##`, `###`, blockquotes, `-` lists, `1.` lists, `**bold**`, `~~strike~~`, horizontal rule, and plain code fences only when necessary. Avoid frontmatter, HTML, tables, footnotes, math, file-name code fences, and Zenn/Qiita blocks. |
+| Zenn | Use Zenn frontmatter and Zenn extensions: code fences may use `language:filename`; diff highlighting uses `diff language`; tips use `:::message`; warnings use `:::message alert`; collapsible sections use `:::details`; link cards use `@[card](URL)`. |
+| Qiita | Use Qiita frontmatter and Qiita extensions: code fences may use `language:filename`; diff highlighting uses `diff_language`; tips/warnings use `:::note info`, `:::note warn`, `:::note alert`; collapsible sections use HTML `<details><summary>...`; math should prefer `math` code fences or inline `$` backtick notation. |
+
+Generation and validation should reject obvious cross-platform leakage:
+
+- note must not output `:::message`, `:::note`, `:::details`, `@[card]`, HTML tables/details, or math blocks.
+- Zenn must not output Qiita `:::note` or `diff_language` fences.
+- Qiita must not output Zenn `:::message`, `:::details`, `@[card]`, or `diff language` fences.
+
+Implementation note: these notation policies are now captured as embedded Markdown guides under `internal/application/draft/format_guides/`. The final draft prompt injects only the selected format's guide, so the model sees concrete editor rules without receiving unrelated platform examples.
+
+## UX implication
+
+The app should not ask users to remember platform rules. The first usable version therefore exposes:
+
+- writer selector,
+- output target selector,
+- source/voice summary,
+- automatic default format per persona,
+- technical extra questions for Zenn / Qiita,
+- homepage CTA questions for HTML sections,
+- format-specific draft validation before showing the result.
+
+## Cor.inc blog generation target
+
+The company blog is an Astro content collection. The immediate practical output should be copy-pasteable Markdown for `corsweb2024/src/content/blog/ja/{slug}.md`, not an abstract blog draft.
+
+Required frontmatter shape:
+
+```yaml
+---
+title: "記事タイトル"
+description: "50-100文字程度の説明"
+pubDate: 2026-05-02
+author: "Terisuke"
+category: "engineering"
+tags: ["AI", "開発", "知見"]
+lang: "ja"
+featured: false
+isDraft: true
+---
+```
+
+Categories are defined in `src/config/categories.ts`: `ai`, `engineering`, `founder`, `lab`. The older guide text omits `engineering`, but the active Astro schema imports category ids from this config, so the app should follow the config.
+
+Practical style constraints:
+
+- Generate Japanese first: `lang: "ja"`.
+- Use direct company-blog prose: mainly `だ` / `である` / `する`.
+- Keep technical knowledge reports concrete: prerequisites, commands/code, verification result, learned constraints.
+- Keep vision-sharing articles useful for employees: why the decision matters, what behavior should change, and how it connects to company direction.
+- Include code fences only with a language marker.
+- Prefer `isDraft: true` for generated output so the pasted file is safe by default.

+- Code fences must specify a language.
+- Include concrete implementation decisions, verification results, or operational lessons.
+
+## Editorial purpose
+
+Use the company blog for:
+
+- company technical knowledge reports,
+- implementation decision records,
+- internal or employee-facing vision sharing,
+- practical lessons that show Cor.inc's capability.
+
+Do not write it like a broad-reader note essay unless the brief explicitly asks for that.

+# note Markdown guide
+
+Use this guide only for `note_article` output.
+
+## Goal
+
+Generate paste-ready Japanese Markdown that converts cleanly in the note editor.
+
+## Allowed notation
+
+- `# タイトル` on the first line for the article title.
+- `## 大見出し`.
+- `### 小見出し`.
+- `> 引用`.
+- `- 箇条書き`.
+- `1. 番号付きリスト`.
+- `**太字**`.
+- `~~取り消し線~~`.
+- `---` for a horizontal rule.
+- Plain fenced code blocks only when code is truly needed.
+
+## Avoid
+
+- YAML frontmatter.
+- HTML blocks.
+- Markdown tables.
+- Footnotes.
+- Math blocks or inline math.
+- Zenn notation: `:::message`, `:::details`, `@[card](...)`.
+- Qiita notation: `:::note info`, `:::note warn`, `:::note alert`.
+- Filename code fences such as `ts:src/main.ts`.
+- Diff-specific code fences.
+
+## Writing bias
+
+Use note for broad-reader essays: technical experiments, personal observations, and ideas that should attract readers beyond a narrow implementation context.

+## Required frontmatter
+
+```yaml
+---
+title: "記事タイトル"
+tags:
+  - Go
+  - AI
+---
+```
+
+`tags` should use discoverable technology names.
+
+## Structure
+
+- Emphasize reproduction: environment, steps, code, result, troubleshooting, references.
+- Keep explanations concrete enough that another engineer can try them immediately.
+
+## Qiita-specific notation
+
+- Filename code fences: ````rb:app.rb````.
+- Diff highlighting: ````diff_ruby````.
+- Tips and warnings:
+  - `:::note info`
+  - `:::note warn`
+  - `:::note alert`
+- Collapsible details: `<details><summary>...</summary>...</details>`.
+- Math block: ````math````.
+- Inline math: prefer Qiita's backtick dollar notation, e.g. `$`x^2 + y^2 = 1`$`.
+- Markdown tables are allowed. HTML tables are acceptable only when Markdown cannot express the table.
+
+## Avoid
+
+- Zenn `:::message`.
+- Zenn `:::message alert`.
+- Zenn `:::details`.
+- Zenn `@[card](...)`.
+- Zenn diff fences such as `diff ts`.

+Evo X2 over the Tailscale SSH tunnel is the correct primary inference path. It passes the full workflow scenario with the intended `gemma4:31b` draft model.
+
+Local llama.cpp is available as a fallback runtime, but the local fallback model set did not meet the draft quality threshold in this run. Follow-up hardening is tracked by Issue [#36](https://github.com/terisuke/note_maker/issues/36).

 ## Summary
 
-Evo X2 over the Tailscale SSH tunnel is the correct primary inference path. It passes the full workflow scenario with the intended `gemma4:31b` draft model.
+Evo X2's OpenAI-compatible API over Tailscale VPN/MagicDNS is the correct primary inference path. It allows every authorized Tailnet device to use the same Evo X2 endpoint without per-device SSH port forwarding.
+
+The previous SSH tunnel validation proved that Evo X2 itself could pass the scenario, but SSH is now treated as a developer diagnostic path only.
 
 Local llama.cpp is available as a fallback runtime, but the local fallback model set did not meet the draft quality threshold in this run. Follow-up hardening is tracked by Issue [#36](https://github.com/terisuke/note_maker/issues/36).

+- ADR 0001's strict Terisuke style threshold work is complete ([#11](https://github.com/terisuke/note_maker/issues/11)).
+- Phase B1 is complete ahead of the original order: `Persona` and `OutputFormat` concepts, prompt dispatch, and format validators are in place ([#21](https://github.com/terisuke/note_maker/issues/21)). The remaining Phase B work stays deferred until after Phase A/C foundations.
+- Evo X2 is the primary heavy-inference runtime through the Tailnet OpenAI-compatible API (`http://evo-x2:11434/v1`). SSH tunnel access is an explicit developer diagnostic only.
+- Runtime validation showed that Tailnet inference can take 20+ minutes and still miss quality gates because of generation variance. Therefore, Phase A should start with streaming and cancellation ([#18](https://github.com/terisuke/note_maker/issues/18)) before the broader transcript rewrite ([#17](https://github.com/terisuke/note_maker/issues/17)). Primary-runtime quality stabilization is tracked separately in [#40](https://github.com/terisuke/note_maker/issues/40).
+
+Near-term execution order:
+
+1. [#18](https://github.com/terisuke/note_maker/issues/18) — streaming LLM responses, progress events, and cancellation for Tailnet Evo X2.
+2. [#17](https://github.com/terisuke/note_maker/issues/17) — chat transcript and editable answer/fork UX, using the streaming primitives from #18.
+3. [#20](https://github.com/terisuke/note_maker/issues/20) — deep-dive rationale display inside the transcript.
+4. [#19](https://github.com/terisuke/note_maker/issues/19) — editable draft and per-section regenerate once streamed drafts are visible and cancellable.
+5. Phase C1 ([#26](https://github.com/terisuke/note_maker/issues/26), extending [#14](https://github.com/terisuke/note_maker/issues/14)) — SQLite history, so answer forks and draft versions survive restarts.

 The phases in [ADR 0002](../adrs/0002-multi-persona-multi-format-extension.md) (A, B, C, D) are tracked as separate issues in the new tranche. Their guardrails extend the rules below:
 
 - Phase A (Conversation UX): no domain changes, only handler streaming + frontend rewrite. Must keep all existing `go test ./...` green without modification.
+- Phase A execution starts with [#18](https://github.com/terisuke/note_maker/issues/18) because Tailnet Evo X2 runs are long enough that spinner-only UX is no longer acceptable. [#17](https://github.com/terisuke/note_maker/issues/17) follows and reuses the streaming primitives.
 - Phase B (Persona / OutputFormat): introduces `internal/domain/persona` and `internal/domain/format`. The note.com host check moves out of application services into `internal/infrastructure/source/note` only.
 - Phase C (SQLite store): repository interfaces stay; only implementations change. JSON-file store becomes import/export utility.
 - Phase D (Quality): handler tests are mandatory before any further endpoint additions land. Coverage gate: `internal/handlers/workflow.go` ≥ 80 %.

+- Runtime stabilization: [#40](https://github.com/terisuke/note_maker/issues/40) for primary Tailnet Evo X2 quality/metrics.
+
+## Next target
+
+Start with [#18](https://github.com/terisuke/note_maker/issues/18), not [#17](https://github.com/terisuke/note_maker/issues/17).
+
+Reason: a real Tailnet Evo X2 scenario reached the correct endpoint but took `1396.80s` and still missed quality gates. A spinner-only UI is not usable at that latency. Streaming, heartbeat, cancellation, and partial-result retention are the highest-leverage improvement before reshaping the transcript.
+
+## Implementation sequence
+
+1. **[#18] SSE streaming and cancellation**
+   - Add streaming to `internal/infrastructure/llamacpp`.
+   - Add status, heartbeat, token, done, and error event types.
+   - Support cancellation from browser disconnect and explicit Cancel.
+   - Keep non-streaming generation for tests and compatibility.
+
+2. **[#17] Chat transcript and editable answers**
+   - Replace the bounded log with a transcript surface.
+   - Render existing fixed and deep-dive answers as bubbles.
+   - Add in-memory fork-on-edit endpoint first; persistence follows in Phase C.
+
+3. **[#20] Deep-dive rationale in transcript**
+   - Add parent-answer excerpts to prompt and UI.
+   - Ensure LLM and rule-based fallback paths produce the same contextual prefix.
+
+4. **[#19] Editable draft and section regenerate**
+   - Make the Markdown draft editable after streaming lands.
+   - Add section anchor parsing and replacement tests.
+   - Regenerate one heading subtree at a time.
+
+5. **[#26] SQLite persistence**
+   - Persist answer forks, draft versions, guide versions, and project/article history.
+
+## Additional gap
+
+[#40](https://github.com/terisuke/note_maker/issues/40) tracks primary-runtime quality and runtime metrics. That work is separate from [#36](https://github.com/terisuke/note_maker/issues/36), which is only for local llama.cpp fallback quality. Do not block [#18](https://github.com/terisuke/note_maker/issues/18) on #40; streaming is needed precisely because these long primary-runtime runs can fail late and still need to preserve partial output.

 - Phase B1 is complete ahead of the original order: `Persona` and `OutputFormat` concepts, prompt dispatch, and format validators are in place ([#21](https://github.com/terisuke/note_maker/issues/21)). The remaining Phase B work stays deferred until after Phase A/C foundations.
 - Evo X2 is the primary heavy-inference runtime through the Tailnet OpenAI-compatible API (`http://evo-x2:11434/v1`). SSH tunnel access is an explicit developer diagnostic only.

 ### A2 — Stream LLM responses via SSE
 
+Implementation status: code path implemented on `codex/issue-18-sse-streaming`; validate against real Tailnet Evo X2 before closing the issue.
+
 - Add SSE support to `internal/infrastructure/llamacpp/client.go` (OpenAI-compatible `stream: true`).
 - Wire streaming through the application services for `follow-up generation` and `draft generation`. Style analysis can stay non-streaming (single short call).
 - Frontend: replace global spinner with token-by-token append into the transcript (for follow-up) or into the draft preview (for draft).

   - Direct local Ollama on `127.0.0.1:11434` must not be used as the default verification path; it is only acceptable when explicitly selected for a one-off diagnostic.

+- Evo X2 Ollama is the primary heavy-inference runtime through the Tailnet OpenAI-compatible API (`http://evo-x2.tailb30e58.ts.net/v1`). The runtime fallback chain is Evo X2 Ollama → Evo X2 llama.cpp (`/llama/v1`) → workstation-local llama.cpp. SSH tunnel access is an explicit developer diagnostic only.
+- Phase model defaults are intentionally split: lightweight `gemma4:e2b` for source/style summarization, `qwen3.6:27b` for deeper interview questions, and `gemma4:31b` for final Japanese draft generation. This is an operational default, not a hard domain rule; users can override it per phase.
 - Runtime validation showed that Tailnet inference can take 20+ minutes and still miss quality gates because of generation variance. Therefore, Phase A started with streaming and cancellation ([#18](https://github.com/terisuke/note_maker/issues/18)) before the broader transcript rewrite ([#17](https://github.com/terisuke/note_maker/issues/17)). Primary-runtime quality stabilization is tracked separately in [#40](https://github.com/terisuke/note_maker/issues/40).
 - Phase A2 is implemented in code: `llamacpp.Client.GenerateStream`, streaming follow-up/draft service paths, `Accept: text/event-stream` handlers, browser Cancel controls, heartbeat events, and final runtime metrics. It still requires real Tailnet Evo X2 validation before closing the issue.

 - Phase B1 is complete ahead of the original order: `Persona` and `OutputFormat` concepts, prompt dispatch, and format validators are in place ([#21](https://github.com/terisuke/note_maker/issues/21)). The remaining Phase B work stays deferred until after Phase A/C foundations.
 - Evo X2 Ollama is the primary heavy-inference runtime through the Tailnet OpenAI-compatible API (`http://evo-x2.tailb30e58.ts.net/v1`). The runtime fallback chain is Evo X2 Ollama → Evo X2 llama.cpp (`/llama/v1`) → workstation-local llama.cpp. SSH tunnel access is an explicit developer diagnostic only.
 - Phase model defaults are intentionally split: lightweight `gemma4:e2b` for source/style summarization, `qwen3.6:27b` for deeper interview questions, and `gemma4:31b` for final Japanese draft generation. This is an operational default, not a hard domain rule; users can override it per phase.
+- Final verification uses lightweight Gemma by default (`gemma4:latest`, currently the Evo X2 E4B-class Ollama model) to check brief coverage, style consistency, output-format notation, and unsupported factual assertions before the UI presents the final draft ([#47](https://github.com/terisuke/note_maker/issues/47)).
 - Runtime validation showed that Tailnet inference can take 20+ minutes and still miss quality gates because of generation variance. Therefore, Phase A started with streaming and cancellation ([#18](https://github.com/terisuke/note_maker/issues/18)) before the broader transcript rewrite ([#17](https://github.com/terisuke/note_maker/issues/17)). Primary-runtime quality stabilization is tracked separately in [#40](https://github.com/terisuke/note_maker/issues/40).
 - Phase A2 is implemented in code: `llamacpp.Client.GenerateStream`, streaming follow-up/draft service paths, `Accept: text/event-stream` handlers, browser Cancel controls, heartbeat events, and final runtime metrics. It still requires real Tailnet Evo X2 validation before closing the issue.

 Runtime validation treats Evo X2 Ollama's OpenAI-compatible API over Tailscale VPN/MagicDNS as the primary heavy-inference path. SSH tunnels are explicit developer diagnostics only. The fallback chain is Evo X2 Ollama → Evo X2 llama.cpp → workstation-local llama.cpp. Scenario reports must include base URL, model, elapsed time, score, and draft length to prevent accidental local-runtime validation. The 2026-05-02 validation passed on Evo X2 and found local fallback quality/model-compatibility gaps; fallback hardening is tracked in Issue [#36](https://github.com/terisuke/note_maker/issues/36). Future llama.cpp model swap orchestration is tracked in Issue [#45](https://github.com/terisuke/note_maker/issues/45).
 
+Draft generation now includes a lightweight final verification pass before returning the final result. The default operational model split is: `gemma4:e2b` for source/style summarization, `qwen3.6:27b` for follow-up question generation, `gemma4:31b` for Japanese draft generation, and `gemma4:latest` for final consistency verification. The verification step reports PASS/NEEDS_REVIEW plus concrete issues; automatic rewrite from the verification report is deferred until section regeneration and draft versioning are in place.

@@ -204,15 +204,15 @@ Current implementation status as of 2026-05-02:
 - Phase model defaults are intentionally split: lightweight `gemma4:e2b` for source/style summarization, `qwen3.6:27b` for deeper interview questions, and `gemma4:31b` for final Japanese draft generation. This is an operational default, not a hard domain rule; users can override it per phase.
 - Final verification uses lightweight Gemma by default (`gemma4:latest`, currently the Evo X2 E4B-class Ollama model) to check brief coverage, style consistency, output-format notation, and unsupported factual assertions before the UI presents the final draft ([#47](https://github.com/terisuke/note_maker/issues/47)).
 - Runtime validation showed that Tailnet inference can take 20+ minutes and still miss quality gates because of generation variance. Therefore, Phase A started with streaming and cancellation ([#18](https://github.com/terisuke/note_maker/issues/18)) before the broader transcript rewrite ([#17](https://github.com/terisuke/note_maker/issues/17)). Primary-runtime quality stabilization is tracked separately in [#40](https://github.com/terisuke/note_maker/issues/40).
-- Phase A2 is implemented in code: `llamacpp.Client.GenerateStream`, streaming follow-up/draft service paths, `Accept: text/event-stream` handlers, browser Cancel controls, heartbeat events, and final runtime metrics. It still requires real Tailnet Evo X2 validation before closing the issue.
+- Phase A2 is implemented and merged: `llamacpp.Client.GenerateStream`, streaming follow-up/draft service paths, `Accept: text/event-stream` handlers, browser Cancel controls, heartbeat events, and final runtime metrics ([#18](https://github.com/terisuke/note_maker/issues/18)).
+- Phase A1 is implemented in code: the interview surface now renders a chat-style transcript, answer bubbles can be edited inline, and edits create child sessions via fork-on-edit while retaining `parent_session_id` lineage ([#17](https://github.com/terisuke/note_maker/issues/17)).
 
 Near-term execution order:
 
-1. Validate and merge [#18](https://github.com/terisuke/note_maker/issues/18) — streaming LLM responses, progress events, and cancellation for Tailnet Evo X2.

 The phases in [ADR 0002](../adrs/0002-multi-persona-multi-format-extension.md) (A, B, C, D) are tracked as separate issues in the new tranche. Their guardrails extend the rules below:
 
-- Phase A (Conversation UX): no domain changes, only handler streaming + frontend rewrite. Must keep all existing `go test ./...` green without modification.
-- Phase A execution starts with [#18](https://github.com/terisuke/note_maker/issues/18) because Tailnet Evo X2 runs are long enough that spinner-only UX is no longer acceptable. [#17](https://github.com/terisuke/note_maker/issues/17) follows and reuses the streaming primitives.

 - Phase B (Persona / OutputFormat): introduces `internal/domain/persona` and `internal/domain/format`. The note.com host check moves out of application services into `internal/infrastructure/source/note` only.
 - Phase C (SQLite store): repository interfaces stay; only implementations change. JSON-file store becomes import/export utility.
 - Phase D (Quality): handler tests are mandatory before any further endpoint additions land. Coverage gate: `internal/handlers/workflow.go` ≥ 80 %.

 - Final verification uses lightweight Gemma by default (`gemma4:latest`, currently the Evo X2 E4B-class Ollama model) to check brief coverage, style consistency, output-format notation, and unsupported factual assertions before the UI presents the final draft ([#47](https://github.com/terisuke/note_maker/issues/47)).
 - Runtime validation showed that Tailnet inference can take 20+ minutes and still miss quality gates because of generation variance. Therefore, Phase A started with streaming and cancellation ([#18](https://github.com/terisuke/note_maker/issues/18)) before the broader transcript rewrite ([#17](https://github.com/terisuke/note_maker/issues/17)). Primary-runtime quality stabilization is tracked separately in [#40](https://github.com/terisuke/note_maker/issues/40).
 - Phase A2 is implemented and merged: `llamacpp.Client.GenerateStream`, streaming follow-up/draft service paths, `Accept: text/event-stream` handlers, browser Cancel controls, heartbeat events, and final runtime metrics ([#18](https://github.com/terisuke/note_maker/issues/18)).
-- Phase A1 is implemented in code: the interview surface now renders a chat-style transcript, answer bubbles can be edited inline, and edits create child sessions via fork-on-edit while retaining `parent_session_id` lineage ([#17](https://github.com/terisuke/note_maker/issues/17)).

+- Phase A4 is implemented in code: follow-up prompts include parent question, parent answer, and active style guide context; rule-based fallback questions use the same quoted parent-answer prefix; the transcript labels the parent answer as the deep-dive rationale ([#20](https://github.com/terisuke/note_maker/issues/20)). Validation is recorded in [Issue 20 deep-dive rationale validation](../validation/issue-20-deep-dive-rationale-2026-05-02.md).

    - Local llama.cpp (`http://127.0.0.1:8081/v1`) is fallback only. Do not set `LLM_BASE_URL` to local Ollama or local llama.cpp for Evo X2 validation unless the test is explicitly measuring fallback behavior.
    - Runtime validation must report base URL, model, elapsed time, score, and draft length.
+   - Each implementation PR that touches interview, prompt, draft, or runtime behavior should add one scenario datapoint with a deliberately varied medium/persona/format. Do not force every PR to rerun every scenario; build averages by collecting one different slice per phase.
    - Draft generation must run the lightweight final verification step before returning the final result; if verification reports NEEDS_REVIEW, surface the report instead of hiding it.
    - If fallback validation fails the strict draft thresholds, keep Evo X2 primary enabled and track fallback hardening separately (Issue [#36](https://github.com/terisuke/note_maker/issues/36)).
    - If Tailnet Evo X2 reaches the API but misses quality gates, track it under Issue [#40](https://github.com/terisuke/note_maker/issues/40), not as a transport regression.

 - Fallback (rule-based) text uses the same prefix to keep tone consistent.

+Implementation note as of 2026-05-02: #20 is implemented in code. Validation used a different medium from the prior note-oriented run: `terisuke` + `markdown_blog` + `cor_blog` brief. The draft-only rerun on Evo X2 Tailnet primary produced `elapsed_seconds=439.86`, `runes=3675`, `score=72.3`, and lightweight verification PASS. The strict note-style threshold of 82 was not met, which is expected signal that company-blog baselines need to be tracked separately from note-style baselines.

+# Issue 20 deep-dive rationale validation - 2026-05-02
+
+Tracks Issue [#20](https://github.com/terisuke/note_maker/issues/20).
+
+## Code checks
+
+```bash
+go test ./...
+node --check static/js/script.js
+git diff --check
+```
+
+Result: pass.
+
+## Scenario variant
+
+This run intentionally differs from the prior note-oriented validation:
+
+- Persona: `terisuke`
+- Output format: `markdown_blog`
+- Brief variant: `cor_blog`
+- Topic: Evo X2 local LLM inference foundation as company technical knowledge and internal vision sharing
+- Primary runtime: `http://evo-x2.tailb30e58.ts.net/v1`
+- Draft model: `gemma4:31b`
+- Verification model: `gemma4:latest`
+
+The goal was not to re-run the exact same note essay. It was to start building per-phase averages across different media and writing modes.
+
+## Full workflow attempt
+
+```bash
+env SCENARIO_BRIEF_VARIANT=cor_blog SCENARIO_OUTPUT_FORMAT_ID=markdown_blog SCENARIO_MIN_DRAFT_RUNES=2200 make scenario-evo-x2
+```
+
+Preflight passed and confirmed the Tailnet OpenAI-compatible API:
+
+```text
+Evo X2 Tailnet LLM API is ready: http://evo-x2.tailb30e58.ts.net/v1/models
+```
+
+Brief interview completed:
+
+```text
+variant=cor_blog
+persona_id=terisuke
+output_format_id=markdown_blog
+answers=13
+deep_dives=4
+elapsed_seconds=240.01
+```
+
+The draft stage failed the strict style gate:
+
+```text
+style score 63.1 below scenario minimum 80.0
+```
+
+Artifacts still showed a usable draft length:
+
+- Draft file: `tmp/draft_generation/draft.md`
+- Characters: `3314`
+- Style score: `63.1`
+- Main failures: `sentence_length=56 below 75`, `first_person=48 below 60`
+- Verification: failed because the old scenario timeout let the verifier reach an expired context and report the workstation-local fallback endpoint.
+
+This exposed two scenario-harness problems fixed in the same PR:
+
+- `cmd/scenario/draft_generation` now prints metrics before exiting non-zero.
+- `llamacpp.Client` no longer falls through to fallback clients after the caller context has expired.
+
+## Draft-only rerun
+
+The existing company-blog brief was reused and local workstation fallback was intentionally removed from the chain:
+
+```bash
+env \
+  RUN_LOCAL_LLM_SCENARIO=1 \
+  SCENARIO_STREAM_DRAFT=1 \
+  SCENARIO_OUTPUT_DIR=tmp/draft_generation_issue20 \
+  AUTHOR_PROFILE_PATH=tmp/author_style/profile.json \
+  WRITING_GUIDE_PATH=tmp/author_style/guide.json \
+  ARTICLE_BRIEF_PATH=tmp/brief_interview/brief.json \
+  LLM_BASE_URL=http://evo-x2.tailb30e58.ts.net/v1 \
+  LLM_MODEL=gemma4:31b \
+  DRAFT_LLM_MODEL=gemma4:31b \
+  VERIFY_LLM_MODEL=gemma4:latest \
+  LLM_TIMEOUT_SECONDS=1200 \
+  SCENARIO_DRAFT_TIMEOUT_SECONDS=1200 \
+  LLM_FALLBACK_BASE_URLS=http://evo-x2.tailb30e58.ts.net/llama/v1 \
+  DRAFT_LLM_FALLBACK_MODELS=gemma-4-E2B-it-Q8_0.gguf \
+  VERIFY_LLM_FALLBACK_MODELS=gemma-4-E2B-it-Q8_0.gguf \
+  SCENARIO_MIN_STYLE_SCORE=60 \
+  SCENARIO_MIN_DRAFT_RUNES=2800 \
+  DRAFT_MAX_ATTEMPTS=1 \
+  go run ./cmd/scenario/draft_generation
+```
+
+Result:
+
+```text
+scenario_passed=true
+attempt=1
+passed=false
+score=72.3
+min_style_score=60.0
+runes=3675
+min_draft_runes=2800
+verification_performed=true
+verification_passed=true
+elapsed_seconds=439.86
+streaming=true
+first_chunk_ms=31573
+chunks=1778
+llm_base_url=http://evo-x2.tailb30e58.ts.net/v1
+llm_model=gemma4:31b
+verify_model=gemma4:latest
+```
+
+Interpretation:
+
+- Tailnet primary path was reachable and used for the scenario.
+- The draft exceeded the 2800-character gate.
+- Lightweight final verification passed.
+- Strict Terisuke-note style score remained below 82 because this scenario deliberately used a company-blog format with the existing note-derived profile. This is useful signal: cross-medium validation should track a separate baseline rather than treating note-style thresholds as universal.

@@ -206,13 +206,13 @@ Current implementation status as of 2026-05-02:
 - Runtime validation showed that Tailnet inference can take 20+ minutes and still miss quality gates because of generation variance. Therefore, Phase A started with streaming and cancellation ([#18](https://github.com/terisuke/note_maker/issues/18)) before the broader transcript rewrite ([#17](https://github.com/terisuke/note_maker/issues/17)). Primary-runtime quality stabilization is tracked separately in [#40](https://github.com/terisuke/note_maker/issues/40).
 - Phase A2 is implemented and merged: `llamacpp.Client.GenerateStream`, streaming follow-up/draft service paths, `Accept: text/event-stream` handlers, browser Cancel controls, heartbeat events, and final runtime metrics ([#18](https://github.com/terisuke/note_maker/issues/18)).
 - Phase A1 is implemented and merged: the interview surface now renders a chat-style transcript, answer bubbles can be edited inline, and edits create child sessions via fork-on-edit while retaining `parent_session_id` lineage ([#17](https://github.com/terisuke/note_maker/issues/17)).
-- Phase A4 is implemented in code: follow-up prompts include parent question, parent answer, and active style guide context; rule-based fallback questions use the same quoted parent-answer prefix; the transcript labels the parent answer as the deep-dive rationale ([#20](https://github.com/terisuke/note_maker/issues/20)). Validation is recorded in [Issue 20 deep-dive rationale validation](../validation/issue-20-deep-dive-rationale-2026-05-02.md).

Validation is recorded in [Issue 20 deep-dive rationale validation](../validation/issue-20-deep-dive-rationale-2026-05-02.md).
+- Phase A3 is implemented in code: the generated Markdown textarea is editable, preview rendering live-syncs through `marked`, both preview and Markdown tabs can copy content, and `POST /api/drafts/{id}/regenerate-section` rewrites exactly one `## ` subtree while preserving the rest of the draft byte-for-byte ([#19](https://github.com/terisuke/note_maker/issues/19)). Validation is recorded in [Issue 19 section regeneration validation](../validation/issue-19-section-regeneration-2026-05-02.md).
 
 Near-term execution order:
 
-1. Merge [#20](https://github.com/terisuke/note_maker/issues/20) — deep-dive rationale display inside the transcript.
-2. [#19](https://github.com/terisuke/note_maker/issues/19) — editable draft and per-section regenerate once streamed drafts are visible and cancellable.
-3. Phase C1 ([#26](https://github.com/terisuke/note_maker/issues/26), extending [#14](https://github.com/terisuke/note_maker/issues/14)) — SQLite history, so answer forks and draft versions survive restarts.

+Implementation note as of 2026-05-02: #19 is implemented in code. The Phase A route uses the existing `session_id` as the draft identifier until Phase C adds versioned draft records. The canonical endpoint is `POST /api/drafts/{id}/regenerate-section`; it loads the stored style guide and brief, applies the current persona/output-format strategy, rejects replacement candidates containing multiple `## ` sections, and returns both the candidate section and the full updated draft. Evo X2 validation regenerated the company-blog `## 実装と検証：再現性の数値化` section in `167.33s`, then completed lightweight verification in `23.14s`; non-target prefix/suffix preservation was true and the score stayed in the prior company-blog band (`72.1` vs `72.3`). Details are in [Issue 19 section regeneration validation](../validation/issue-19-section-regeneration-2026-05-02.md).

+# Issue 19 section regeneration validation
+
+Date: 2026-05-02
+
+## Scope
+
+Validate [#19](https://github.com/terisuke/note_maker/issues/19): editable draft Markdown plus one-section regeneration.
+
+The runtime scenario used the prior Phase A4 company-blog draft so this run differs from the earlier note-style runs while still measuring the same Evo X2 Tailnet primary path.
+
+## Runtime
+
+- Base URL: `http://evo-x2.tailb30e58.ts.net/v1`
+- Draft model: `gemma4:31b`
+- Verification model: `gemma4:latest`
+- Persona: `terisuke`
+- Output format: `markdown_blog`
+- Source draft: `tmp/draft_generation_issue20/draft.md`
+- Target section: `## 実装と検証：再現性の数値化`
+- Output directory: `tmp/section_regeneration_issue19`
+
+## Results
+
+| Metric | Value |
+|---|---:|
+| Section regeneration elapsed | 167.33s |
+| Lightweight verification elapsed | 23.14s |
+| Updated draft length | 4011 runes |
+| Replacement length | 1336 runes |
+| Style score | 72.1 |
+| Lightweight verification | PASS |
+| Non-target prefix unchanged | true |
+| Non-target suffix unchanged | true |
+
+Comparison to Issue 20 company-blog draft run:
+
+| Run | Elapsed | Runes | Score | Verification |
+|---|---:|---:|---:|---|
+| Issue 20 full draft | 439.86s | 3675 | 72.3 | PASS |
+| Issue 19 section regenerate | 167.33s + 23.14s verify | 4011 | 72.1 | PASS |
+
+## Observations
+
+- The section replacement preserved every byte before and after the target `## ` subtree.
+- The score stayed in the same band as the previous company-blog run (`72.1` vs `72.3`), which supports treating this as medium/style variance rather than a #19 regression.
+- The strict Terisuke note-style threshold still fails for company-blog drafts because paragraph and sentence lengths are longer than the note baseline. This remains a cross-medium baseline issue, not a section-regeneration bug.
+- The first scenario attempt used a shortened anchor (`実装と検証`) and correctly failed because anchors require the exact heading/normalized anchor.
+- A second attempt used the correct heading but hit the client default `LLM_TIMEOUT_SECONDS=180` before Evo X2 returned response headers. The successful run set both the scenario timeout and LLM client timeout to 600 seconds.
+- The lightweight verifier summary contains a typo (`Tailsale互換API`). The verifier still returned PASS, so this is recorded as a quality signal for future verifier-prompt tightening rather than a blocker for #19.

+# Issue 22 source fetcher validation
+
+Date: 2026-05-02
+
+## Scope
+
+Validate [#22](https://github.com/terisuke/note_maker/issues/22): route source acquisition beyond note.com to Zenn, Qiita, RSS/Atom, and generic HTML while keeping normal tests offline.
+
+## Current source facts checked
+
+- Qiita API v2 documents `GET /api/v2/users/:user_id/items` as the public user item list endpoint in newest order, with `page` and `per_page` parameters.
+- Qiita API v2 documents unauthenticated access as limited to `60` requests per hour per IP address, so the fetcher uses one request per user-list scenario and no polling loop.
+- Zenn's official RSS article documents user feeds as `https://zenn.dev/ユーザー名/feed`.
+- Zenn's official RSS article documents `?all=1` for including all public posts instead of the default limited feed, so the Zenn fetcher uses that query for user lists.
+- RSS/Atom parsing is implemented through standard XML feeds, with RSS 2.0 item fields and Atom entries handled in one `RSSFetcher`.
+
+## Implementation
+
+- `internal/domain/source` defines `Kind`, `Ref`, `ProfileSnapshot`, and `ArticleSnapshot`.
+- `internal/infrastructure/source.Router` dispatches by explicit selector or URL host:
+  - `note:<user>` and note.com URLs go to the existing note fetcher.
+  - `zenn:<user>` and zenn.dev URLs go to Zenn RSS/HTML fetchers.
+  - `qiita:<user>` and qiita.com URLs go to Qiita API v2 fetchers.
+  - `rss:<url>` and feed-like URLs go to RSS/Atom parsing.
+  - `html:<url>` and unknown article URLs go to semantic HTML extraction.
+- `AnalyzeAuthorStyleHandler` and the legacy article-generation handler now use the router through an adapter that still satisfies the existing `FetchArticle` / `FetchUserLatestArticles` application interface.
+
+## Scenario
+
+Command:
+
+```bash
+RUN_SOURCE_FETCH_SCENARIO=1 \
+SCENARIO_OUTPUT_DIR=tmp/source_fetch_issue22 \
+SOURCE_FETCH_NOTE=note:cor_instrument \
+SOURCE_FETCH_ZENN=zenn:zenn \
+SOURCE_FETCH_QIITA=qiita:Qiita \
+SOURCE_FETCH_RSS=rss:https://zenn.dev/zenn/feed \
+go run ./cmd/scenario/source_fetch
+```
+
+Result:
+
+| Source | Selector | Articles | Elapsed | Output |
+|---|---|---:|---:|---|
+| Qiita | `qiita:Qiita` | 1 | 0.68s | `tmp/source_fetch_issue22/qiita.json` |
+| RSS | `rss:https://zenn.dev/zenn/feed` | 1 | 0.18s | `tmp/source_fetch_issue22/rss.json` |
+| note | `note:cor_instrument` | 1 | 0.66s | `tmp/source_fetch_issue22/note.json` |
+| Zenn | `zenn:zenn` | 1 | 0.19s | `tmp/source_fetch_issue22/zenn.json` |
+
+Recent-source check:
+
+- Qiita returned `Qiita アップデートサマリー - 2026年4月`, which is inside the requested recent two-month window from 2026-05-02.
+- Zenn/RSS returned Zenn official content from the current public feed path.
+- note returned the latest public `cor_instrument` article available through the existing note source path.
+
+## Tests
+
+```bash
+go test ./...
+```
+
+Focused source tests cover:
+
+- RSS 2.0 `content:encoded` parsing.
+- Atom entry parsing.
+- explicit `zenn:`, `qiita:`, and `rss:` selector routing.
+- host-based routing for note.com, zenn.dev, qiita.com, RSS-like URLs, and generic HTML.

 - Phase A4 is implemented and merged: follow-up prompts include parent question, parent answer, and active style guide context; rule-based fallback questions use the same quoted parent-answer prefix; the transcript labels the parent answer as the deep-dive rationale ([#20](https://github.com/terisuke/note_maker/issues/20)). Validation is recorded in [Issue 20 deep-dive rationale validation](../validation/issue-20-deep-dive-rationale-2026-05-02.md).

+
+- [#23](https://github.com/terisuke/note_maker/issues/23) format-specific prompt templates and validators.
+- [#24](https://github.com/terisuke/note_maker/issues/24) seeded persona library for `terisuke` and `cloudia`.
+
+It deliberately does not cover source-fetcher generalisation ([#22](https://github.com/terisuke/note_maker/issues/22)), SQLite persistence ([#26](https://github.com/terisuke/note_maker/issues/26)), or handler coverage expansion ([#29](https://github.com/terisuke/note_maker/issues/29)).
+
+## What changed
+
+- Strengthened `internal/domain/format` validators:
+  - note rejects HTML blocks in addition to platform-specific notation and filename/diff fences.
+  - Zenn requires boolean `published`, inline `topics` with at most five items, and rejects HTML details.
+  - Qiita rejects empty `tags`.
+  - homepage sections reject frontmatter, code fences, and Markdown headings.
+- Added unit coverage for the stricter format cases.
+- Added unit coverage proving seeded personas reference registered default formats and expected source kinds.
+- Added deterministic scenario command `cmd/scenario/format_persona_seed`.
+
+## Scenario
+
+Command:
+
+```sh
+go run ./cmd/scenario/format_persona_seed
+```
+
+Result:
+
+```text
+format/persona seed scenario completed
+personas=2
+formats=5
+samples=5
+summary=tmp/format_persona_seed/summary.json
+```
+
+The scenario validates all registered format samples through `article.NewDraftForFormat`, checks embedded format-guide injection through `draft.BuildPromptForMode`, writes prompt hints for both seeded personas, and exercises these persona/format samples:
+
+- `terisuke_note`
+- `terisuke_blog`
+- `cloudia_zenn`
+- `cloudia_qiita`
+- `terisuke_homepage`
+
+## Acceptance status
+
+- Each validator has positive and negative unit coverage: done.
+- Each registered format has an embedded guide injected into the draft prompt: done.
+- Same writing brief can be represented under visibly different target surfaces: covered by deterministic scenario samples.
+- Seed library includes `terisuke` and `cloudia`, with distinct default formats, source bundles, first-person hints, title patterns, and anti-patterns: done.
+
+Live source-derived guide rebuilding for Zenn/Qiita/RSS remains dependent on [#22](https://github.com/terisuke/note_maker/issues/22), so it is not part of this validation.

 - Qiita API v2 documents unauthenticated access as limited to `60` requests per hour per IP address, so the fetcher uses one request per user-list scenario and no polling loop.
 - Zenn's official RSS article documents user feeds as `https://zenn.dev/ユーザー名/feed`.

 - RSS/Atom parsing is implemented through standard XML feeds, with RSS 2.0 item fields and Atom entries handled in one `RSSFetcher`.

Validation is recorded in [Issue 20 deep-dive rationale validation](../validation/issue-20-deep-dive-rationale-2026-05-02.md).

Validation is recorded in [Issue 19 section regeneration validation](../validation/issue-19-section-regeneration-2026-05-02.md).
 - Phase B3/B4 are implemented for the in-repo registry surface: all five formats have prompt fragments, embedded guides, and validators; `terisuke` and `cloudia` ship as distinct seed personas. Deterministic scenario validation is recorded in [Issue 23/24 format and persona seed validation](../validation/issue-23-24-format-persona-seed-2026-05-02.md).

+# Media matrix integrated evaluation
+
+Date: 2026-05-03
+
+## Scope
+
+This validation plan covers the integrated cross-media path after the new source selectors and output modes are available. It intentionally starts offline and deterministic, then documents the live source/LLM runs to execute when a local model and network access are explicitly enabled.
+
+The evaluation must vary all of these dimensions:
+
+- Theme: reflective creation, implementation report, company vision, Zenn tutorial, Qiita how-to, homepage copy.
+- Medium: note, Cor.inc company blog, Zenn, Qiita, homepage HTML section.
+- Style: essay, technical report, vision sharing, tutorial, practical how-to, concise product section.
+- Length: 400-700字 homepage copy through 3000字 note essay.
+
+## Offline matrix scenario
+
+Command:
+
+```sh
+SCENARIO_OUTPUT_DIR=tmp/media_matrix go run ./cmd/scenario/media_matrix
+```
+
+Expected output:
+
+```text
+media matrix scenario completed
+offline_only=true
+source_selectors=5
+question_template_ids=9
+composed_templates=10
+cases=6
+matrix=tmp/media_matrix/matrix.json
+cases_markdown=tmp/media_matrix/cases.md
+```
+
+The command does not call public sources or an LLM. It verifies:
+
+- Seeded personas expose these proven selectors:
+  - `note:cor_instrument`
+  - `zenn:cloudia`
+  - `qiita:Cloudia_Cor_Inc`
+  - `rss:https://cor-jp.com/rss.xml`
+  - `github:Cor-Incorporated/corsweb2024/src/content/blog/ja`
+- The baseline Terisuke note interview template still contains the required brief fields.
+- All 10 composed templates across 2 personas x 5 formats are generated, including Cloudia technical questions and homepage CTA questions.
+- Each case can assemble a completed `ArticleBrief` through the domain session flow using its own `persona_id x output_format_id` question template.
+- Each case prompt contains the expected persona, output format, theme, target length, and medium-specific guide fragments.
+
+Artifacts:
+
+- `tmp/media_matrix/matrix.json`: machine-readable planned run matrix.
+- `tmp/media_matrix/cases.md`: human-readable matrix and per-case live LLM command.
+- `tmp/media_matrix/briefs/*.json`: deterministic `ArticleBrief` inputs for draft generation.
+- `tmp/media_matrix/prompts/*.prompt.md`: generated prompts for inspection.
+
+## Matrix cases
+
+The offline scenario currently covers:
+
+| Case | Medium | Style | Primary selectors |
+|---|---|---|---|
+| `terisuke_note_essay` | note | reflective essay | `note:cor_instrument` |
+| `cor_blog_technical_report` | Cor.inc company blog | technical report | `rss:https://cor-jp.com/rss.xml`, `github:Cor-Incorporated/corsweb2024/src/content/blog/ja` |
+| `cor_blog_vision_sharing` | Cor.inc company blog | vision sharing | `rss:https://cor-jp.com/rss.xml`, `github:Cor-Incorporated/corsweb2024/src/content/blog/ja` |
+| `cloudia_zenn_tutorial` | Zenn | tutorial | `zenn:cloudia` |
+| `cloudia_qiita_how_to` | Qiita | practical how-to | `qiita:Cloudia_Cor_Inc` |
+| `cor_homepage_section` | homepage | concise product section | `rss:https://cor-jp.com/rss.xml`, `github:Cor-Incorporated/corsweb2024/src/content/blog/ja` |
+
+## Optional live source phase
+
+Run only when live network validation is intended:
+
+```sh
+RUN_SOURCE_FETCH_SCENARIO=1 \
+SCENARIO_OUTPUT_DIR=tmp/source_fetch_media_matrix \
+SOURCE_FETCH_LIMIT=100 \
+SOURCE_FETCH_NOTE=note:cor_instrument \
+SOURCE_FETCH_ZENN=zenn:cloudia \
+SOURCE_FETCH_QIITA=qiita:Cloudia_Cor_Inc \
+SOURCE_FETCH_RSS=rss:https://cor-jp.com/rss.xml \
+SOURCE_FETCH_GITHUB=github:Cor-Incorporated/corsweb2024/src/content/blog/ja \
+go run ./cmd/scenario/source_fetch
+```
+
+2026-05-03 live result:
+
+| Selector | Articles | Avg content length | Elapsed seconds | Output |
+|---|---:|---:|---:|---|
+| `note:cor_instrument` | 20 | 5,177 chars | 8.91 | `tmp/source_fetch_media_matrix/note.json` |
+| `zenn:cloudia` | 7 | 4,139 chars | 1.06 | `tmp/source_fetch_media_matrix/zenn.json` |
+| `qiita:Cloudia_Cor_Inc` | 12 | 3,274 chars | 0.30 | `tmp/source_fetch_media_matrix/qiita.json` |
+| `rss:https://cor-jp.com/rss.xml` | 10 | 69 chars | 0.10 | `tmp/source_fetch_media_matrix/rss.json` |
+| `github:Cor-Incorporated/corsweb2024/src/content/blog/ja` | 10 | 4,218 chars | 2.61 | `tmp/source_fetch_media_matrix/github.json` |
+
+## Optional live LLM phase
+
+First generate the offline matrix so the brief files exist:
+
+```sh
+SCENARIO_OUTPUT_DIR=tmp/media_matrix go run ./cmd/scenario/media_matrix
+```
+
+Then run draft generation for one case at a time with an available local LLM and style artifacts. Example:
+
+```sh
+RUN_LOCAL_LLM_SCENARIO=1 \
+AUTHOR_PROFILE_PATH=tmp/author_style/profile.json \
+WRITING_GUIDE_PATH=tmp/author_style/guide.json \
+ARTICLE_BRIEF_PATH=tmp/media_matrix/briefs/cloudia_zenn_tutorial.json \
+SCENARIO_OUTPUT_DIR=tmp/media_matrix/live/cloudia_zenn_tutorial \
+go run ./cmd/scenario/draft_generation
+```
+
+Use the `planned_llm_command` entries in `tmp/media_matrix/matrix.json` or `tmp/media_matrix/cases.md` for the remaining cases, adding `AUTHOR_PROFILE_PATH` and `WRITING_GUIDE_PATH` to point at the style artifacts for the phase under test.
+
+## Comparison table
+
+Compare results across phases and cases with this schema:
+
+| Case | Phase | Medium | Style | Target length | Elapsed seconds | Score | Verification passed | Runes | Output |
+|---|---|---|---|---|---:|---:|---|---:|---|
+| `terisuke_note_essay` | offline matrix | note | reflective essay | 3000字前後 |  |  | prompt checks only |  | `tmp/media_matrix/prompts/terisuke_note_essay.prompt.md` |
+| `terisuke_note_essay` | live draft | note | reflective essay | 3000字前後 |  |  |  |  |  |
+| `cor_blog_technical_report` | live draft | company blog | technical report | 2200-2800字 |  |  |  |  |  |
+| `cor_blog_vision_sharing` | live draft | company blog | vision sharing | 1600-2200字 |  |  |  |  |  |
+| `cloudia_zenn_tutorial` | live draft | Zenn | tutorial | 1800-2400字 |  |  |  |  |  |
+| `cloudia_qiita_how_to` | live draft | Qiita | practical how-to | 1400-2000字 |  |  |  |  |  |
+| `cor_homepage_section` | live draft | homepage | concise product section | 400-700字 |  |  |  |  |  |
+
+Acceptance criteria for the integrated evaluation:
+
+- Offline matrix passes before any live work.
+- Live source phase confirms each selector still returns usable material, with GitHub Markdown preferred over RSS for full Cor.inc blog body text.
+- Each live draft records `elapsed_seconds`, style `score`, `passed`, `verification_performed`, `verification_passed`, and `runes` from `cmd/scenario/draft_generation`.
+- Failures are grouped by dimension: source selector, persona, medium/output format, style, target length, or verifier result.

-Recommended order: A → C → B → D. Phase C is sequenced before the remaining B work because the persona registry needs durable storage to be useful; running the full persona library on the JSON store would force a second migration.
+Original recommended order was A → C → B → D. Implementation intentionally pulled the minimum B work forward because source acquisition, format validation, persona seeds, and question templates were required before a realistic cross-media evaluation could be defined. With Phases A and B now implemented, the next order is C1 + D1 in parallel, then C2/C3, then the full Evo X2 media-matrix evaluation under #40.

 - Phase B1 is complete ahead of the original order: `Persona` and `OutputFormat` concepts, prompt dispatch, and format validators are in place ([#21](https://github.com/terisuke/note_maker/issues/21)). The remaining Phase B work stays deferred until after Phase A/C foundations.
@@ -209,13 +209,14 @@ Current implementation status as of 2026-05-02:
 - Phase A1 is implemented and merged: the interview surface now renders a chat-style transcript, answer bubbles can be edited inline, and edits create child sessions via fork-on-edit while retaining `parent_session_id` lineage ([#17](https://github.com/terisuke/note_maker/issues/17)).
 - Phase A4 is implemented and merged: follow-up prompts include parent question, parent answer, and active style guide context; rule-based fallback questions use the same quoted parent-answer prefix; the transcript labels the parent answer as the deep-dive rationale ([#20](https://github.com/terisuke/note_maker/issues/20)). Validation is recorded in [Issue 20 deep-dive rationale validation](../validation/issue-20-deep-dive-rationale-2026-05-02.md).
 - Phase A3 is implemented in code: the generated Markdown textarea is editable, preview rendering live-syncs through `marked`, both preview and Markdown tabs can copy content, and `POST /api/drafts/{id}/regenerate-section` rewrites exactly one `## ` subtree while preserving the rest of the draft byte-for-byte ([#19](https://github.com/terisuke/note_maker/issues/19)). Validation is recorded in [Issue 19 section regeneration validation](../validation/issue-19-section-regeneration-2026-05-02.md).
-- Phase B3/B4 are implemented for the in-repo registry surface: all five formats have prompt fragments, embedded guides, and validators; `terisuke` and `cloudia` ship as distinct seed personas. Deterministic scenario validation is recorded in [Issue 23/24 format and persona seed validation](../validation/issue-23-24-format-persona-seed-2026-05-02.md). Live source-derived guide rebuilding for Zenn/Qiita/RSS remains part of source acquisition work in [#22](https://github.com/terisuke/note_maker/issues/22).
+- Phase B2/B3/B4 are implemented: historical source acquisition works for note, Zenn, Qiita, Cor RSS, and Cor GitHub Markdown; all five formats have prompt fragments, embedded guides, and validators; `terisuke` and `cloudia` ship as distinct seed personas. Validation is recorded in [Issue 22 source fetcher validation](../validation/issue-22-source-fetchers-2026-05-02.md) and [Issue 23/24 format and persona seed validation](../validation/issue-23-24-format-persona-seed-2026-05-02.md).
 - Phase B5 is implemented: fixed interview questions are composed server-side by `persona_id × output_format_id`, Cloudia technical modes include extra viewpoint/context prompts, the frontend reads `GET /api/brief-sessions/templates`, and `cmd/scenario/media_matrix` produces a six-case cross-media evaluation matrix for note, Cor blog, Zenn, Qiita, and homepage output ([#25](https://github.com/terisuke/note_maker/issues/25)).
 
 Near-term execution order:
 
-1. Merge [#19](https://github.com/terisuke/note_maker/issues/19) — editable draft and per-section regenerate on top of the streamed draft surface.
-2. Phase C1 ([#26](https://github.com/terisuke/note_maker/issues/26), extending [#14](https://github.com/terisuke/note_maker/issues/14)) — SQLite history, so answer forks and draft versions survive restarts and section-regeneration candidates can become versioned draft records.

+2. Phase D1 ([#29](https://github.com/terisuke/note_maker/issues/29)) in parallel with C1 — raise `workflow.go` handler coverage before more endpoint-heavy UI work lands.
+3. Runtime stabilization ([#40](https://github.com/terisuke/note_maker/issues/40), with runner implementation in [#57](https://github.com/terisuke/note_maker/issues/57)) — use `cmd/scenario/media_matrix` to run varied Note/Qiita/Zenn/Cor blog Evo X2 cases and record endpoint/model/elapsed/score/runes/verification. Full multi-case runs should happen after C1 unless the user explicitly wants one-off artifact files.

[#19](https://github.com/terisuke/note_maker/issues/19) is the final Phase A UX cut before Phase C persistence.

-Reason: a real Tailnet Evo X2 scenario reached the correct endpoint but took `1396.80s` and still missed quality gates. A spinner-only UI is not usable at that latency. Streaming, heartbeat, cancellation, and partial-result retention are the highest-leverage improvement before reshaping the transcript.

-## Implementation sequence
+The homepage section case remains in the matrix as a useful format check, but the user-facing publishing targets for the full Evo X2 run are note, Qiita, Zenn, and the company blog.
 
-1. **[#18] SSE streaming and cancellation**
-   - Add streaming to `internal/infrastructure/llamacpp`.
-   - Add status, heartbeat, token, done, and error event types.
-   - Support cancellation from browser disconnect and explicit Cancel.
-   - Keep non-streaming generation for tests and compatibility.
-   - Status: implemented and merged.
+Each live run must record:
 
-2. **[#17] Chat transcript and editable answers**
-   - Replace the bounded log with a transcript surface.
-   - Render existing fixed and deep-dive answers as bubbles.
-   - Add in-memory fork-on-edit endpoint first; persistence follows in Phase C.
-   - Status: implemented and merged.
+- endpoint and whether it was primary or fallback,
+- model per phase,
+- elapsed seconds,
+- generated runes,
+- style score and failed metrics,
+- final verification result,
+- output path and scenario case id.
 
-3. **[#20] Deep-dive rationale in transcript**
-   - Add parent-answer excerpts to prompt and UI.
-   - Ensure LLM and rule-based fallback paths produce the same contextual prefix.
-   - Status: implemented and merged.
+## Before the full Evo X2 media run
 
-4. **[#19] Editable draft and section regenerate**
-   - Make the Markdown draft editable after streaming lands.
-   - Add section anchor parsing and replacement tests.
-   - Regenerate one heading subtree at a time.
-   - Status: implemented in code; merge before moving to #26.
+There are three prerequisites before running the full multi-medium Evo X2 evaluation:
 
-5. **[#26] SQLite persistence**
-   - Persist answer forks, draft versions, guide versions, and project/article history.
+1. **Persistence first**: #26 must land so media-matrix drafts, evaluations, regenerated sections, answer forks, and style guides can be saved and reopened. Repeated Evo X2 runs are too expensive to leave only as loose files.
+2. **Handler coverage gate**: #29 should run in parallel with #26 and must close before more endpoint-heavy UI work. #17-#25 added real handler surface; the next phase should harden it instead of adding more unguarded routes.
+3. **Scenario ownership**: #40 owns the live Evo X2 media-matrix quality target. [#57](https://github.com/terisuke/note_maker/issues/57) owns the reusable runner/aggregate evaluator that executes the matrix and writes comparable reports.
 
-## Additional gap
+## Parallel implementation plan
 
-[#40](https://github.com/terisuke/note_maker/issues/40) tracks primary-runtime quality and runtime metrics. That work is separate from [#36](https://github.com/terisuke/note_maker/issues/36), which is only for local llama.cpp fallback quality. Do not block [#18](https://github.com/terisuke/note_maker/issues/18) on #40; streaming is needed precisely because these long primary-runtime runs can fail late and still need to preserve partial output.
+Use subagents with disjoint write scopes:
+
+| Lane | Issue | Subagent role | Write scope | Done when |
+|---|---|---|---|---|
+| A | [#26](https://github.com/terisuke/note_maker/issues/26) / [#14](https://github.com/terisuke/note_maker/issues/14) | SQLite worker | `internal/infrastructure/repository/sqlite`, repository interfaces, boot wiring, migrations | JSON store imports, sessions/guides/briefs/drafts persist, cross-persona tests pass |
+| B | [#29](https://github.com/terisuke/note_maker/issues/29) | Handler coverage worker | `internal/handlers/*_test.go`, coverage script/docs | `workflow.go` reaches the agreed coverage gate without real LLM/network |
+| C | [#57](https://github.com/terisuke/note_maker/issues/57), feeding [#40](https://github.com/terisuke/note_maker/issues/40) | Scenario metrics worker | `cmd/scenario/*`, `docs/validation/*`, Make targets | media-matrix live runner records endpoint/model/elapsed/score/runes/verification in aggregate JSON/Markdown |
+
+Lane A and Lane B can run immediately in parallel. Lane C can start by implementing offline/resumable runner mechanics now, but the full multi-case Evo X2 run should wait until Lane A provides persistence or until the user explicitly wants a one-off artifact-file run.
+
+## Recommended order
+
+1. Merge this docs alignment PR.
+2. Start #26 and #29 in parallel.
+3. Merge #29 as soon as handler coverage is sufficient.
+4. Merge #26 once JSON import, SQLite schema, and restart recovery are proven.
+5. Use #57/#40 to run one media-matrix case per implementation phase, then run the full note/Qiita/Zenn/company-blog pass after the persistence layer is stable.
+6. Start #27 and #28 after #26; both depend on persistent projects/sessions/guides.
+7. Start #13 after #27/#28 have enough browser surface to justify E2E tests.
+8. Keep #36/#45 as fallback/runtime P2 work and #15 as packaging after persistence/history are usable.
+
+## Why not run the full Evo X2 matrix now?
+
+The source and prompt matrix is ready, but full Evo X2 draft generation is expensive and can take 20+ minutes per run. Running all media cases before persistence would produce useful files but not durable product memory. The better sequence is to make the system capable of storing those expensive results, then use #40 to evaluate one varied slice per phase and finally run the full comparison table.

@@ -211,12 +211,15 @@ Current implementation status as of 2026-05-03:
 - Phase A3 is implemented in code: the generated Markdown textarea is editable, preview rendering live-syncs through `marked`, both preview and Markdown tabs can copy content, and `POST /api/drafts/{id}/regenerate-section` rewrites exactly one `## ` subtree while preserving the rest of the draft byte-for-byte ([#19](https://github.com/terisuke/note_maker/issues/19)). Validation is recorded in [Issue 19 section regeneration validation](../validation/issue-19-section-regeneration-2026-05-02.md).
 - Phase B2/B3/B4 are implemented: historical source acquisition works for note, Zenn, Qiita, Cor RSS, and Cor GitHub Markdown; all five formats have prompt fragments, embedded guides, and validators; `terisuke` and `cloudia` ship as distinct seed personas. Validation is recorded in [Issue 22 source fetcher validation](../validation/issue-22-source-fetchers-2026-05-02.md) and [Issue 23/24 format and persona seed validation](../validation/issue-23-24-format-persona-seed-2026-05-02.md).
 - Phase B5 is implemented: fixed interview questions are composed server-side by `persona_id × output_format_id`, Cloudia technical modes include extra viewpoint/context prompts, the frontend reads `GET /api/brief-sessions/templates`, and `cmd/scenario/media_matrix` produces a six-case cross-media evaluation matrix for note, Cor blog, Zenn, Qiita, and homepage output ([#25](https://github.com/terisuke/note_maker/issues/25)).
+- Phase C1 is implemented in the current cut: `internal/infrastructure/repository/sqlite` adds migrations and storage for author styles, sessions, briefs, projects, articles, source snapshots, draft versions, final verification, and section-regeneration versions. The web app can opt in with `WORKFLOW_STORE_DRIVER=sqlite`; the JSON store remains the default compatibility path ([#26](https://github.com/terisuke/note_maker/issues/26)).
+- Phase D1 is implemented in the current cut: handler tests now cover template selection, edit/fork errors, SSE follow-up and draft paths, completed-session draft fallback, regenerate-section context recovery, Analyze/Generate compatibility handlers, and SQLite driver selection. `go test ./internal/handlers -cover` reports 80.0% statement coverage ([#29](https://github.com/terisuke/note_maker/issues/29)).
+- Runtime runner support is implemented in the current cut: `cmd/scenario/live_media_matrix` reads the offline matrix, emits planned aggregate JSON/Markdown by default, and executes live Evo X2 draft runs only when `RUN_LIVE_MEDIA_MATRIX=1` or `make scenario-media-matrix-live` is used ([#57](https://github.com/terisuke/note_maker/issues/57)).
 
 Near-term execution order:
 
-1. Phase C1 ([#26](https://github.com/terisuke/note_maker/issues/26), extending [#14](https://github.com/terisuke/note_maker/issues/14)) — SQLite history, so answer forks, source-derived guides, media-matrix briefs, draft versions, and evaluation records survive restarts.
-2. Phase D1 ([#29](https://github.com/terisuke/note_maker/issues/29)) in parallel with C1 — raise `workflow.go` handler coverage before more endpoint-heavy UI work lands.
-3. Runtime stabilization ([#40](https://github.com/terisuke/note_maker/issues/40), with runner implementation in [#57](https://github.com/terisuke/note_maker/issues/57)) — use `cmd/scenario/media_matrix` to run varied Note/Qiita/Zenn/Cor blog Evo X2 cases and record endpoint/model/elapsed/score/runes/verification. Full multi-case runs should happen after C1 unless the user explicitly wants one-off artifact files.
+1. Phase C2/C3 ([#27](https://github.com/terisuke/note_maker/issues/27), [#28](https://github.com/terisuke/note_maker/issues/28)) — expose persisted sessions, guides, briefs, drafts, and verification artifacts in the web app.
+2. Runtime stabilization ([#40](https://github.com/terisuke/note_maker/issues/40)) — first run one bounded media-matrix case through `cmd/scenario/live_media_matrix`, then run the full Note/Qiita/Zenn/Cor blog Evo X2 comparison once the UI can reuse the stored outputs.
+3. Browser E2E ([#13](https://github.com/terisuke/note_maker/issues/13)) — cover persona/format switching, edit/fork, streaming, section regeneration, and persisted-history recovery after C2/C3 has visible browser surface.

+- New package `internal/infrastructure/repository/sqlite` using `mattn/go-sqlite3`.
 - Schema migrations under `internal/infrastructure/repository/sqlite/migrations/` numbered `0001_*.sql`, applied at boot via a tiny in-process migrator.
 - Tables (minimum): `personas`, `author_sources`, `writing_style_guides` (versioned), `projects`, `articles`, `brief_sessions`, `brief_answers` (with `parent_answer_id`), `drafts` (versioned).
-- The existing JSON file becomes an export/import utility. On first boot, if the JSON file exists, it is imported.

-1. Merge this docs alignment PR.
-2. Start #26 and #29 in parallel.
-3. Merge #29 as soon as handler coverage is sufficient.
-4. Merge #26 once JSON import, SQLite schema, and restart recovery are proven.
-5. Use #57/#40 to run one media-matrix case per implementation phase, then run the full note/Qiita/Zenn/company-blog pass after the persistence layer is stable.
-6. Start #27 and #28 after #26; both depend on persistent projects/sessions/guides.
-7. Start #13 after #27/#28 have enough browser surface to justify E2E tests.
-8. Keep #36/#45 as fallback/runtime P2 work and #15 as packaging after persistence/history are usable.
+1. Merge the current #26/#29/#57 implementation PR.
+2. Run one bounded Evo X2 live case through #57 and attach it to #40 to verify the runner with real latency/score data.
+3. Start #27 and #28 in parallel so persisted sessions, guides, and draft artifacts become visible in the web app.
+4. Start #13 once the history/artifact UI has enough stable browser surface.
+5. Run the full note/Qiita/Zenn/company-blog media matrix under #40.

 文体分析結果、取材セッションの回答、完成ブリーフは `WORKFLOW_STORE_PATH` にJSONとして永続化されます。既定値は `data/workflow_store.json` です。
 
-SQLiteを試す場合は `WORKFLOW_STORE_DRIVER=sqlite` を指定します。既定パスは `data/workflow_store.db` で、`WORKFLOW_STORE_PATH` で変更できます。JSON store は互換性のため既定のまま残しています。
+保存方式は設定画面の「保存方式」から選べます。UIで変更した内容は `data/app_config.json` に保存され、サーバー再起動後に反映されます。SQLiteを選んだ場合の既定パスは `data/workflow_store.db` です。JSON store は互換性のため既定のまま残しています。
+
+開発・検証で強制したい場合は `WORKFLOW_STORE_DRIVER=sqlite` を指定できます。この環境変数がある場合、設定画面では保存方式がロック表示になります。

@@ -211,15 +211,17 @@ Current implementation status as of 2026-05-03:
 - Phase A3 is implemented in code: the generated Markdown textarea is editable, preview rendering live-syncs through `marked`, both preview and Markdown tabs can copy content, and `POST /api/drafts/{id}/regenerate-section` rewrites exactly one `## ` subtree while preserving the rest of the draft byte-for-byte ([#19](https://github.com/terisuke/note_maker/issues/19)). Validation is recorded in [Issue 19 section regeneration validation](../validation/issue-19-section-regeneration-2026-05-02.md).
 - Phase B2/B3/B4 are implemented: historical source acquisition works for note, Zenn, Qiita, Cor RSS, and Cor GitHub Markdown; all five formats have prompt fragments, embedded guides, and validators; `terisuke` and `cloudia` ship as distinct seed personas. Validation is recorded in [Issue 22 source fetcher validation](../validation/issue-22-source-fetchers-2026-05-02.md) and [Issue 23/24 format and persona seed validation](../validation/issue-23-24-format-persona-seed-2026-05-02.md).
 - Phase B5 is implemented: fixed interview questions are composed server-side by `persona_id × output_format_id`, Cloudia technical modes include extra viewpoint/context prompts, the frontend reads `GET /api/brief-sessions/templates`, and `cmd/scenario/media_matrix` produces a six-case cross-media evaluation matrix for note, Cor blog, Zenn, Qiita, and homepage output ([#25](https://github.com/terisuke/note_maker/issues/25)).
-- Phase C1 is implemented in the current cut: `internal/infrastructure/repository/sqlite` adds migrations and storage for author styles, sessions, briefs, projects, articles, source snapshots, draft versions, final verification, and section-regeneration versions. The web app can opt in with `WORKFLOW_STORE_DRIVER=sqlite`; the JSON store remains the default compatibility path ([#26](https://github.com/terisuke/note_maker/issues/26)).
-- Phase D1 is implemented in the current cut: handler tests now cover template selection, edit/fork errors, SSE follow-up and draft paths, completed-session draft fallback, regenerate-section context recovery, Analyze/Generate compatibility handlers, and SQLite driver selection. `go test ./internal/handlers -cover` reports 80.0% statement coverage ([#29](https://github.com/terisuke/note_maker/issues/29)).
-- Runtime runner support is implemented in the current cut: `cmd/scenario/live_media_matrix` reads the offline matrix, emits planned aggregate JSON/Markdown by default, and executes live Evo X2 draft runs only when `RUN_LIVE_MEDIA_MATRIX=1` or `make scenario-media-matrix-live` is used ([#57](https://github.com/terisuke/note_maker/issues/57)).
+- Phase C1 is implemented and merged: `internal/infrastructure/repository/sqlite` adds migrations and storage for author styles, sessions, briefs, projects, articles, source snapshots, draft versions, final verification, and section-regeneration versions. The JSON store remains the compatibility path, while storage mode can now be inspected and switched from the web settings UI unless environment variables lock it ([#26](https://github.com/terisuke/note_maker/issues/26), [#61](https://github.com/terisuke/note_maker/issues/61)).
+- Phase D1 is implemented and merged: handler tests now cover template selection, edit/fork errors, SSE follow-up and draft paths, completed-session draft fallback, regenerate-section context recovery, Analyze/Generate compatibility handlers, and SQLite driver selection. `go test ./internal/handlers -cover` reports 80%+ statement coverage ([#29](https://github.com/terisuke/note_maker/issues/29)).
+- Runtime runner support is implemented and merged: `cmd/scenario/live_media_matrix` reads the offline matrix, emits planned aggregate JSON/Markdown by default, and executes live Evo X2 draft runs only when `RUN_LIVE_MEDIA_MATRIX=1` or `make scenario-media-matrix-live` is used ([#57](https://github.com/terisuke/note_maker/issues/57)).
+- The 2026-05-03 browser 500 analysis showed an implementation drift: plain web-app startup still defaulted to workstation-local `127.0.0.1:8081`, while this ADR requires Evo X2 Tailnet as primary. Issue [#63](https://github.com/terisuke/note_maker/issues/63) restores the default order to Evo X2 Ollama over Tailnet → Evo X2 llama.cpp → workstation-local llama.cpp and makes the UI show the actual endpoint/model reported by SSE.
 
 Near-term execution order:

+# Runtime UI and DDD alignment audit - 2026-05-03
+
+## Scope
+
+This audit reconciles the current implementation with ADR 0002, the open issue set, and the browser failure reported on 2026-05-03.
+
+## Browser failure analysis
+
+Observed while the app was running from the plain server defaults:
+
+- `GET /api/models` returned HTTP 500 because the LLM client attempted `http://127.0.0.1:8081/v1/models` and the connection was refused.
+- `POST /api/drafts` with `Accept: text/event-stream` returned HTTP 200, then emitted `event: error` with `DRAFT_GENERATION_FAILED` because `http://127.0.0.1:8081/v1/chat/completions` was refused.
+- `GET /favicon.ico` returned 404. This was noisy but not the draft-generation failure.
+
+Root cause: the Makefile remote path already used Evo X2 Tailnet, but plain web-app startup and the LLM client default still treated workstation-local llama.cpp as the primary endpoint. That contradicts the intended order recorded in ADR 0002 and the guardrails:
+
+1. Evo X2 Ollama over Tailscale OpenAI-compatible API.
+2. Evo X2 llama.cpp over Tailscale OpenAI-compatible API.
+3. Workstation-local llama.cpp as the last fallback.
+
+## Fix in this cut
+
+Issue [#63](https://github.com/terisuke/note_maker/issues/63) restores the runtime order for normal browser use:
+
+- `internal/infrastructure/llamacpp` now defaults to `http://evo-x2.tailb30e58.ts.net/v1`.
+- When that default is used, fallback endpoints are `http://evo-x2.tailb30e58.ts.net/llama/v1` and then `http://127.0.0.1:8081/v1`.
+- Phase defaults now match the current operational plan: style/article `gemma4:e2b`, brief `qwen3.6:27b`, draft `gemma4:31b`, verify `gemma4:latest`.
+- `make dev` and `scripts/dev.sh` default to remote runtime instead of starting workstation-local llama.cpp.
+- The draft UI reports the actual SSE endpoint/model on `runtime_connected`.
+- `/favicon.ico` returns 204 to remove the unrelated browser-console noise.
+
+## Verification in this cut
+
+Commands run from a plain `PORT=18080 go run ./cmd/server` startup:
+
+- `curl -i http://127.0.0.1:18080/favicon.ico` returned `HTTP/1.1 204 No Content`.
+- `curl -i http://127.0.0.1:18080/api/models` returned `HTTP/1.1 200 OK` with Evo X2 model IDs including `gemma4:e2b`, `gemma4:latest`, `gemma4:31b`, `qwen3.6:27b`, and `qwen3.6:35b`.
+
+This proves the browser-visible model endpoint no longer defaults to the failed workstation-local `127.0.0.1:8081` path. A full draft-generation score run remains under #40 because it is a live Evo X2 quality/latency measurement, not a startup-routing smoke test.
+
+## Issue state
+
+Merged and no longer current-cut work:
+
+- #11, #17, #18, #19, #20: Phase A and strict Terisuke style work.
+- #21, #22, #23, #24, #25: Phase B persona, format, source, seed, and question-template work.
+- #26: SQLite workflow store foundation.
+- #29: handler coverage.
+- #57: live media-matrix runner.
+- #61: storage driver settings UI.
+
+Open work that still matters:
+
+- #63: runtime default correction and browser evaluation unblocker.
+- #40: actual Tailnet Evo X2 quality/runtime scoring across media.
+- #27 and #28: history picker plus readable brief/style/draft artifacts.
+- #13: browser E2E over the now-stable UI flows.
+- #14: umbrella for queryable product memory beyond the schema foundation.
+- #36 and #45: fallback quality and llama.cpp swap as P2 runtime work.
+- #15: desktop/app-like packaging after the browser workflow is stable.
+
+## DDD alignment
+
+The implementation is partly aligned with DDD:
+
+- Domain concepts are explicit: `internal/domain/persona`, `internal/domain/format`, `internal/domain/brief`, `internal/domain/author`, and `internal/domain/article`.
+- Application services own core workflow behavior: `internal/application/brief` handles interview progression and fork-on-edit; `internal/application/draft` handles prompt assembly, validation, section regeneration, scoring, and lightweight verification.
+- Infrastructure adapters are separated for LLM access, source fetching, JSON memory, and SQLite persistence.
+- HTTP handlers mostly translate request/response shapes into domain/application calls rather than embedding persona or format rules directly.
+
+Known deviations remain:
+
+- `internal/handlers/workflow.go` is still too large and coordinates store lookup, runtime construction, SSE, compatibility handlers, and application calls in one file.
+- LLM clients are constructed directly in handlers. A runtime provider/use-case boundary would make Evo X2/fallback behavior easier to test and configure from the UI.
+- The SQLite repository persists the right data, but the UI does not yet expose projects, article history, draft versions, verification history, or source snapshots as queryable product memory. That is why #14 stays open.
+- Runtime configuration now has storage UI parity, but LLM endpoint/fallback configuration is still env/default driven. #63 fixes the default and visibility problem; a future settings surface can make runtime selection explicit.
+- The frontend is still one static JavaScript file. That is acceptable for the current local-first prototype, but #13 should lock behavior with browser E2E before #27/#28 add more stateful UI.
+
+Conclusion: the domain model and application services match ADR 0002 well enough to continue. The largest architectural risk is not the domain vocabulary; it is handler-led orchestration and hidden runtime configuration. The next implementation sequence should reduce those two risks before the full Evo X2 media-matrix evaluation.

@@ -215,10 +215,11 @@ Current implementation status as of 2026-05-03:
 - Phase D1 is implemented and merged: handler tests now cover template selection, edit/fork errors, SSE follow-up and draft paths, completed-session draft fallback, regenerate-section context recovery, Analyze/Generate compatibility handlers, and SQLite driver selection. `go test ./internal/handlers -cover` reports 80%+ statement coverage ([#29](https://github.com/terisuke/note_maker/issues/29)).
 - Runtime runner support is implemented and merged: `cmd/scenario/live_media_matrix` reads the offline matrix, emits planned aggregate JSON/Markdown by default, and executes live Evo X2 draft runs only when `RUN_LIVE_MEDIA_MATRIX=1` or `make scenario-media-matrix-live` is used ([#57](https://github.com/terisuke/note_maker/issues/57)).
 - The 2026-05-03 browser 500 analysis showed an implementation drift: plain web-app startup still defaulted to workstation-local `127.0.0.1:8081`, while this ADR requires Evo X2 Tailnet as primary. Issue [#63](https://github.com/terisuke/note_maker/issues/63) restores the default order to Evo X2 Ollama over Tailnet → Evo X2 llama.cpp → workstation-local llama.cpp and makes the UI show the actual endpoint/model reported by SSE.
+- The interview question set was simplified before the next Evo X2 run ([#66](https://github.com/terisuke/note_maker/issues/66)): broad editorial questions are now split into smaller plain-Japanese prompts, medium-specific prompts cover note/Zenn/Qiita/Cor blog needs, and optional questions can be advanced as `未定`. Validation is recorded in [Issue 66 plain brief questions validation](../validation/issue-66-plain-brief-questions-2026-05-03.md).
 
 Near-term execution order:
 
-1. Runtime default verification ([#63](https://github.com/terisuke/note_maker/issues/63)) — confirm the browser app no longer reaches for workstation-local inference first and that favicon noise is removed.
+1. Browser sanity check for the #66 interview flow — confirm the new smaller questions are easier to answer before spending Evo X2 runtime.
 2. Phase C2/C3 ([#27](https://github.com/terisuke/note_maker/issues/27), [#28](https://github.com/terisuke/note_maker/issues/28)) — expose persisted sessions, guides, briefs, drafts, and verification artifacts in the web app.
 3. Runtime stabilization ([#40](https://github.com/terisuke/note_maker/issues/40)) — first run one bounded media-matrix case through `cmd/scenario/live_media_matrix`, then run the full Note/Qiita/Zenn/Cor blog Evo X2 comparison once the UI can reuse the stored outputs.
 4. Browser E2E ([#13](https://github.com/terisuke/note_maker/issues/13)) — cover persona/format switching, edit/fork, streaming, section regeneration, and persisted-history recovery after C2/C3 has visible browser surface.

+# Issue 66 plain brief questions validation - 2026-05-03
+
+## Goal
+
+Before live Evo X2 measurement, reduce the user's answering burden in the brief interview. The previous fixed questions were too broad and editorial, which made the one-question-at-a-time flow feel mentally heavy.
+
+## Implementation
+
+- Rewrote the base fixed questions in plain Japanese.
+- Split broad prompts into smaller prompts:
+  - reader problem,
+  - key takeaway,
+  - concrete example,
+  - evidence,
+  - title or heading keywords.
+- Expanded medium-specific prompts:
+  - note: emotional/story arc,
+  - Zenn/Qiita: stack, prerequisite knowledge, reproduction proof, code examples, references,
+  - Cor company blog: technical report vs vision-sharing purpose and desired reader reaction.
+- Softened fallback follow-up wording so it asks for one concrete scene, step, number, feeling, or reason.
+- Updated the LLM follow-up prompt to request shorter, easier questions and avoid difficult editorial terms.
+- The UI now wraps template question text, labels required/optional questions, and lets optional questions advance as `未定` when the answer box is empty.
+- Additional question answers now keep their question label in the final draft prompt instead of being appended as unlabeled fragments.
+
+## Verification
+
+Commands:
+
+```bash
+go test ./internal/domain/brief ./internal/application/brief ./internal/application/draft ./internal/handlers ./cmd/scenario/media_matrix
+node --check static/js/script.js
+go run ./cmd/scenario/media_matrix
+```
+
+Result:
+
+- All checks passed.
+- Offline media matrix completed with `question_template_ids=14`, `composed_templates=10`, and `cases=6`.
+
+## Remaining measurement
+
+This change intentionally does not run the live Evo X2 media matrix. The next step is to run one bounded #40 case after confirming the new interview flow is usable in the browser, then proceed to the full Note/Qiita/Zenn/Cor blog comparison.

@@ -216,10 +216,11 @@ Current implementation status as of 2026-05-03:
 - Runtime runner support is implemented and merged: `cmd/scenario/live_media_matrix` reads the offline matrix, emits planned aggregate JSON/Markdown by default, and executes live Evo X2 draft runs only when `RUN_LIVE_MEDIA_MATRIX=1` or `make scenario-media-matrix-live` is used ([#57](https://github.com/terisuke/note_maker/issues/57)).
 - The 2026-05-03 browser 500 analysis showed an implementation drift: plain web-app startup still defaulted to workstation-local `127.0.0.1:8081`, while this ADR requires Evo X2 Tailnet as primary. Issue [#63](https://github.com/terisuke/note_maker/issues/63) restores the default order to Evo X2 Ollama over Tailnet → Evo X2 llama.cpp → workstation-local llama.cpp and makes the UI show the actual endpoint/model reported by SSE.
 - The interview question set was simplified before the next Evo X2 run ([#66](https://github.com/terisuke/note_maker/issues/66)): broad editorial questions are now split into smaller plain-Japanese prompts, medium-specific prompts cover note/Zenn/Qiita/Cor blog needs, and optional questions can be advanced as `未定`. Validation is recorded in [Issue 66 plain brief questions validation](../validation/issue-66-plain-brief-questions-2026-05-03.md).
+- Style analysis is now persona/format-aware ([#68](https://github.com/terisuke/note_maker/issues/68)): the web UI shows a general `文体ソース` selector instead of `Noteユーザー名`, defaults it to note/Zenn/Qiita/Cor GitHub Markdown based on the selected mode, and makes persona presets include output-format notes. Validation is recorded in [Issue 68 media-aware style source validation](../validation/issue-68-media-aware-style-source-2026-05-03.md).
 
 Near-term execution order:
 
-1. Browser sanity check for the #66 interview flow — confirm the new smaller questions are easier to answer before spending Evo X2 runtime.
+1. Browser sanity check for the #66/#68 setup — confirm both the smaller questions and the style source change when switching note/Zenn/Qiita/Cor blog modes.
 2. Phase C2/C3 ([#27](https://github.com/terisuke/note_maker/issues/27), [#28](https://github.com/terisuke/note_maker/issues/28)) — expose persisted sessions, guides, briefs, drafts, and verification artifacts in the web app.

 4. Browser E2E ([#13](https://github.com/terisuke/note_maker/issues/13)) — cover persona/format switching, edit/fork, streaming, section regeneration, and persisted-history recovery after C2/C3 has visible browser surface.

+# Issue 68 media-aware style source validation - 2026-05-03
+
+## Problem
+
+The interview question template changed with persona and output format, but the style analysis panel still looked and behaved like a note-only input. That made the company blog mode misleading: users could select `会社ブログ`, see company-blog questions, and still derive style from note unless they manually knew the hidden source selector syntax.
+
+## Implementation
+
+- Renamed the UI input from `Noteユーザー名` to `文体ソース`.
+- The UI now defaults the source selector from the selected persona and output format:
+  - `terisuke + note_article` -> `note:cor_instrument`
+  - `terisuke + markdown_blog` -> `github:Cor-Incorporated/corsweb2024/src/content/blog/ja`
+  - `terisuke + homepage_section` -> `github:Cor-Incorporated/corsweb2024/src/content/blog/ja`
+  - `cloudia + zenn_article` -> `zenn:cloudia`
+  - `cloudia + qiita_article` -> `qiita:Cloudia_Cor_Inc`
+- `POST /api/author-style/analyze` now accepts `persona_id`, `output_format_id`, and `source_selector`.
+- If the user leaves the source selector blank, the server picks the same persona/format-aware default source.
+- Persona presets are now format-aware: the generated preset guide includes output-format notes and uses the appropriate source URL.
+- The Cor company blog persona source now uses the canonical GitHub Markdown path as its `Ref`, so it can be passed directly to the source router.
+
+## Verification
+
+Commands:
+
+```bash
+go test ./internal/handlers ./internal/domain/persona ./internal/infrastructure/source
+node --check static/js/script.js
+git diff --check
+```
+
+Result:
+
+- All checks passed.
+
+## Remaining
+
+Before #40 live Evo X2 scoring, do a browser sanity check that switching the output format changes both:
+
+- the `文体ソース` default,
+- the brief question template.

@@ -217,13 +217,15 @@ Current implementation status as of 2026-05-03:
 - The 2026-05-03 browser 500 analysis showed an implementation drift: plain web-app startup still defaulted to workstation-local `127.0.0.1:8081`, while this ADR requires Evo X2 Tailnet as primary. Issue [#63](https://github.com/terisuke/note_maker/issues/63) restores the default order to Evo X2 Ollama over Tailnet → Evo X2 llama.cpp → workstation-local llama.cpp and makes the UI show the actual endpoint/model reported by SSE.
 - The interview question set was simplified before the next Evo X2 run ([#66](https://github.com/terisuke/note_maker/issues/66)): broad editorial questions are now split into smaller plain-Japanese prompts, medium-specific prompts cover note/Zenn/Qiita/Cor blog needs, and optional questions can be advanced as `未定`. Validation is recorded in [Issue 66 plain brief questions validation](../validation/issue-66-plain-brief-questions-2026-05-03.md).
 - Style analysis is now persona/format-aware ([#68](https://github.com/terisuke/note_maker/issues/68)): the web UI shows a general `文体ソース` selector instead of `Noteユーザー名`, defaults it to note/Zenn/Qiita/Cor GitHub Markdown based on the selected mode, and makes persona presets include output-format notes. Validation is recorded in [Issue 68 media-aware style source validation](../validation/issue-68-media-aware-style-source-2026-05-03.md).
+- The 2026-05-03 full Tailnet Evo X2 media-matrix run proved that the runtime path works but also proved that the current scenario is not sufficient as an interview-template acceptance test: only `terisuke_note_essay` passed, Cor blog failed on assistant preamble leakage, Zenn/Qiita failed on cross-format notation leakage, and homepage failed long-form gates despite being a short HTML section. Runtime stabilization is therefore decomposed under epic [#40](https://github.com/terisuke/note_maker/issues/40) into [#70](https://github.com/terisuke/note_maker/issues/70) template/brief scenario coverage, [#71](https://github.com/terisuke/note_maker/issues/71) failed draft artifacts, [#72](https://github.com/terisuke/note_maker/issues/72) bounded format repair, [#73](https://github.com/terisuke/note_maker/issues/73) output-format-specific gates, and [#74](https://github.com/terisuke/note_maker/issues/74) staged Evo X2 reruns.
 
 Near-term execution order:
 
-1. Browser sanity check for the #66/#68 setup — confirm both the smaller questions and the style source change when switching note/Zenn/Qiita/Cor blog modes.
-2. Phase C2/C3 ([#27](https://github.com/terisuke/note_maker/issues/27), [#28](https://github.com/terisuke/note_maker/issues/28)) — expose persisted sessions, guides, briefs, drafts, and verification artifacts in the web app.
-3. Runtime stabilization ([#40](https://github.com/terisuke/note_maker/issues/40)) — first run one bounded media-matrix case through `cmd/scenario/live_media_matrix`, then run the full Note/Qiita/Zenn/Cor blog Evo X2 comparison once the UI can reuse the stored outputs.
-4. Browser E2E ([#13](https://github.com/terisuke/note_maker/issues/13)) — cover persona/format switching, edit/fork, streaming, section regeneration, and persisted-history recovery after C2/C3 has visible browser surface.
+1. Add an interview-template scenario ([#70](https://github.com/terisuke/note_maker/issues/70)) before spending more Evo X2 runtime. It must prove that the simplified questions are small, medium-specific, and able to produce distinct `ArticleBrief` outputs for note, Cor blog, Zenn, Qiita, and homepage.
+2. Make failed generation diagnosable ([#71](https://github.com/terisuke/note_maker/issues/71)) and recoverable when the issue is format-only ([#72](https://github.com/terisuke/note_maker/issues/72)).
+3. Split scenario gates by output format ([#73](https://github.com/terisuke/note_maker/issues/73)) so homepage HTML is not judged as a long article while note/Zenn/Qiita/Cor blog remain strict.
+4. Re-run Evo X2 in stages ([#74](https://github.com/terisuke/note_maker/issues/74)): template scenario, offline media matrix, one previously failing live case, then the full note/Qiita/Zenn/Cor blog comparison.
+5. Continue Phase C2/C3 ([#27](https://github.com/terisuke/note_maker/issues/27), [#28](https://github.com/terisuke/note_maker/issues/28)) and Browser E2E ([#13](https://github.com/terisuke/note_maker/issues/13)) in parallel where write scopes do not conflict.

 ## Recommended order
 
-1. Browser-check the #66/#68 setup with note, one technical format, and Cor company blog. Confirm both the question template and `文体ソース` default change before spending Evo X2 runtime.
-2. Run one bounded Evo X2 live case through #57 and attach it to #40 to verify the runner with real latency/score data.
-3. Start #27 and #28 in parallel so persisted sessions, guides, and draft artifacts become visible in the web app.
-4. Start #13 once the history/artifact UI has enough stable browser surface.
-5. Run the full note/Qiita/Zenn/company-blog media matrix under #40.
+1. Implement #70 first. This proves the revised questions and generated briefs before any more expensive live draft runs.
+2. Implement #71/#72/#73 in parallel where possible. These directly address the failures observed on 2026-05-03.
+3. Run one bounded Evo X2 live case from a previously failing medium, not the already-passing note case.
+4. Start or continue #27/#28 so expensive live outputs can be viewed and reused from the web app.
+5. Run the full note/Qiita/Zenn/company-blog matrix under #74, then update #40 with the aggregate.
 6. Keep #36/#45 as fallback/runtime P2 work and #15 as packaging after persistence/history are usable.
 
 ## Why not run the full Evo X2 matrix now?
 
-The source and prompt matrix is ready, but full Evo X2 draft generation is expensive and can take 20+ minutes per run. Running all media cases before persistence would produce useful files but not durable product memory. The better sequence is to make the system capable of storing those expensive results, then use #40 to evaluate one varied slice per phase and finally run the full comparison table.
+The source and prompt matrix is ready, but full Evo X2 draft generation is expensive and can take 20+ minutes per run.

+# Issue 40 epic decomposition
+
+Date: 2026-05-03
+
+## Context
+
+The full Tailnet Evo X2 media-matrix run completed against the primary OpenAI-compatible API path, but only `terisuke_note_essay` passed. The failures were useful, but they also showed that the scenario plan needed one more layer before implementation:
+
+- The draft-only live matrix starts from completed `ArticleBrief` fixtures, so it cannot prove that the revised fixed questions are actually easier to answer.
+- Early unusable drafts were discarded before enough diagnostic artifacts were written.
+- Some failures were recoverable format errors: assistant preamble leakage and Zenn/Qiita notation leakage.
+- The homepage section was judged with long-form article assumptions.
+
+## Epic
+
+[#40](https://github.com/terisuke/note_maker/issues/40) remains open as the runtime stabilization epic. It should not close until staged validation and consecutive-run acceptance criteria are met.
+
+## Sub-issues
+
+| Order | Issue | Scope | Why it exists |
+|---:|---|---|---|
+| 1 | [#70](https://github.com/terisuke/note_maker/issues/70) | Interview-template scenario | Proves question-template usability and medium-specific brief output before Evo X2 draft generation. |

+| 5 | [#74](https://github.com/terisuke/note_maker/issues/74) | Staged Evo X2 rerun | Runs template/offline/live validation in the correct order and records results back to #40. |
+
+## Implementation order
+
+1. Implement #70.
+2. Implement #71/#72/#73 in parallel only if write scopes stay disjoint.
+3. Run one live Evo X2 case from a previously failing medium.
+4. Run the full note/Qiita/Zenn/Cor blog matrix only after the scenario and diagnostic gaps are closed.

+# Issue 70 interview-template scenario validation - 2026-05-03
+
+## Goal
+
+Add an offline preflight before Evo X2 live media runs. The preflight validates that every built-in persona/output-format pair composes the expected interview template and can produce a simulated `ArticleBrief` without network access, LLM calls, or draft generation.
+
+## Implementation
+
+- Added `cmd/scenario/interview_template`.
+- The scenario covers both seeded personas across all five output formats:
+  - `terisuke`
+  - `cloudia`
+  - `note_article`
+  - `markdown_blog`
+  - `zenn_article`
+  - `qiita_article`
+  - `homepage_section`
+- Each case starts the real `brief.InterviewService` with a nil follow-up generator, answers the composed fixed questions with deterministic scripted inputs, and lets the domain fallback generate deep-dive prompts.
+- Each case writes:
+  - the completed interview session JSON,
+  - the simulated `ArticleBrief` JSON,
+  - template and brief checks in `report.json`.
+- The scenario intentionally does not call draft generation, live media matrix code, runtime LLM clients, or network-backed source fetchers.
+
+## Verification
+
+Commands:
+
+```bash
+go test ./cmd/scenario/interview_template
+go run ./cmd/scenario/interview_template
+```
+
+Result:
+
+- Targeted scenario tests passed.
+- Deterministic scenario run passed with:
+  - `offline_only=true`
+  - `cases=10`
+  - `question_templates=10`
+  - `briefs=10`
+- Generated artifacts:
+  - `tmp/interview_template/report.json`
+  - `tmp/interview_template/cases.md`
+  - `tmp/interview_template/briefs/*.json`
+  - `tmp/interview_template/sessions/*.json`
+
+## Pre-live gate
+
+Before running `cmd/scenario/live_media_matrix` in live mode, run:
+
+```bash
+go run ./cmd/scenario/interview_template
+```
+
+Proceed only when every case in `tmp/interview_template/cases.md` reports `passed`.

+# Issue #71/#72 failed draft artifacts and format repair
+
+Date: 2026-05-03
+
+## Scope
+
+Implemented two related runtime-stabilization changes:
+
+- [#71](https://github.com/terisuke/note_maker/issues/71): preserve failed draft artifacts and runtime metrics.
+- [#72](https://github.com/terisuke/note_maker/issues/72): add one bounded format-repair retry for recoverable format failures.
+
+## Behavior
+
+- `draft.GenerateResult` now includes raw `GenerationAttempt` records for accepted generations and style revisions.
+- Format validation failures return `draft.UnusableDraftError`, preserving raw model output and validation errors.
+- `cmd/scenario/draft_generation` writes:
+  - `raw_attempt_N_generation_M_KIND.txt`
+  - `failure_attempt_N.json`
+- `failure_attempt_N.json` records:
+  - validation error,
+  - elapsed seconds,
+  - timeout seconds,
+  - streaming/first-chunk/chunk metrics,
+  - endpoint/model context,
+  - persona and output format,
+  - raw output artifact paths.
+- `cmd/scenario/live_media_matrix` reads `failure_attempt_N.json` and restores elapsed time, model context, failure path, and raw output paths into aggregate rows.
+- Recoverable format failures get one repair prompt. Validators remain strict.
+
+## Validator fixes from live evidence
+
+The Zenn staged live rerun showed two overly broad validator behaviors:
+
+- Zenn/Qiita cross-format markers inside explanatory code fences or inline examples should not be treated as actual platform syntax leakage.
+- Frontmatter formats should not run the legacy note-only preamble heuristic against body text after YAML frontmatter.
+
+Both are now covered by domain tests.
+
+## Verification
+
+Commands:
+
+```sh
+go test ./cmd/scenario/draft_generation ./cmd/scenario/live_media_matrix ./internal/application/draft ./internal/domain/article ./internal/domain/format
+go test ./...
+```
+
+Results:
+
+- Targeted tests passed.
+- Full test suite passed.
+
+## Live evidence
+
+The first Zenn live rerun after #71/#72 wrote failure diagnostics instead of returning an opaque `0.00s` row:
+
+- Case: `cloudia_zenn_tutorial`
+- Endpoint: `http://evo-x2.tailb30e58.ts.net/v1`
+- Draft model: `gemma4:31b`
+- Verify model: `gemma4:latest`
+- Elapsed: `723.51s`
+- First chunk: `143343ms`
+- Chunks: `1874`
+- Failure path: `tmp/media_matrix/live/cloudia_zenn_tutorial/failure_attempt_1.json`
+- Raw outputs:
+  - `tmp/media_matrix/live/cloudia_zenn_tutorial/raw_attempt_1_generation_1_initial.txt`
+  - `tmp/media_matrix/live/cloudia_zenn_tutorial/raw_attempt_1_generation_2_format_repair.txt`
+
+This run exposed the validator overreach fixed above.

+# Issue #73 output-format-specific scenario gates
+
+Date: 2026-05-03
+
+## Scope
+
+Implemented output-format-specific gates for the media matrix scenarios without changing draft generation internals.
+
+Owned areas changed:
+
+- `cmd/scenario/media_matrix`
+- `cmd/scenario/live_media_matrix`
+- `docs/validation`
+
+## Gate Policy
+
+| Case | Gate policy |
+|---|---|
+| `terisuke_note_essay` | min style `82.0`, min runes `2800`, note long-form structure |
+| `cor_blog_technical_report` | min style `80.0`, min runes `2200`, Cor blog report/frontmatter/verification structure |
+| `cor_blog_vision_sharing` | min style `80.0`, min runes `1600`, Cor blog company-policy/frontmatter structure |
+| `cloudia_zenn_tutorial` | min style `82.0`, min runes `1800`, Zenn frontmatter/topics/message/code structure |
+| `cloudia_qiita_how_to` | min style `82.0`, min runes `1400`, Qiita frontmatter/note/diff/repro structure |
+| `cor_homepage_section` | min style `72.0`, min runes `350`, short HTML `section`/`h2`/`p`/CTA/concise-copy structure |
+
+The homepage section intentionally uses a short HTML gate instead of long-form article length. Note, Cor blog, Zenn, and Qiita remain strict long-form gates.
+

+# Issue #74 staged Evo X2 rerun
+
+Date: 2026-05-03
+
+## Scope
+
+Ran the first staged Tailnet Evo X2 validation slice after implementing #70-#73.
+
+This was intentionally limited to one previously failing medium:
+
+- Case: `cloudia_zenn_tutorial`
+- Medium: Zenn
+- Previous failure class: format validation failed before draft/evaluation artifacts were available.
+
+## Command
+
+```sh
+LIVE_MEDIA_MATRIX_CASES=cloudia_zenn_tutorial make scenario-media-matrix-live
+```
+
+Runtime:
+
+- Endpoint: `http://evo-x2.tailb30e58.ts.net/v1`
+- Draft model: `gemma4:31b`
+- Verify model: `gemma4:latest`
+- Transport: Tailscale VPN / OpenAI-compatible API
+
+## Result
+
+The final rerun did not pass the strict gate, but it progressed past the previous format-failure layer:
+
+| Case | Status | Seconds | First chunk | Chunks | Score / min | Runes / min | Verification |
+|---|---|---:|---:|---:|---:|---:|---|
+| `cloudia_zenn_tutorial` | failed | `702.17` | `169491ms` | `1435` | `73.6 / 82.0` | `3905 / 1800` | passed |
+
+Artifacts:
+
+- Aggregate: `tmp/media_matrix/live/aggregate.json`
+- Report: `tmp/media_matrix/live/aggregate.md`
+- Draft: `tmp/media_matrix/live/cloudia_zenn_tutorial/draft.md`
+- Evaluation: `tmp/media_matrix/live/cloudia_zenn_tutorial/evaluation.json`
+- Verification: `tmp/media_matrix/live/cloudia_zenn_tutorial/verification.json`
+
+## Interpretation
+
+This is a useful staged failure:
+
+- The Tailnet path worked.
+- The Zenn format validator accepted the generated article.
+- The rune gate passed.
+- Lightweight final verification passed.
+- The remaining failure is strict style score: `73.6`, below the Zenn gate `82.0`.
+
+Issue #74 should remain open. The next implementation work should tune Cloudia/Zenn style scoring or prompt calibration before the full note/Qiita/Zenn/Cor blog live matrix is rerun.

-- Each live draft records `elapsed_seconds`, style `score`, `passed`, `verification_performed`, `verification_passed`, and `runes` from `cmd/scenario/draft_generation`.
+- Each live draft records `elapsed_seconds`, style `score`, `min_style_score`, `passed`, `verification_performed`, `verification_passed`, `runes`, `min_draft_runes`, and `active_gates` from `cmd/scenario/draft_generation` and the media matrix.
+- Homepage acceptance is based on short HTML section signals (`section`, `h2`, paragraph, CTA, concise copy), not long-form article length.
+- Long-form note, Cor blog, Zenn, and Qiita acceptance stays strict through their per-case style and rune minimums.
 - Failures are grouped by dimension: source selector, persona, medium/output format, style, target length, or verifier result.

+## 2026-05-03 staged Zenn live slice
+
+After #70-#73 implementation, the first staged live rerun used the previously failing `cloudia_zenn_tutorial` case:
+
+```sh
+LIVE_MEDIA_MATRIX_CASES=cloudia_zenn_tutorial make scenario-media-matrix-live
+```
+
+Final result:
+
+| Case | Status | Seconds | Score / min | Runes / min | Verification | Failure class |
+|---|---|---:|---:|---:|---|---|
+| `cloudia_zenn_tutorial` | failed | `702.17` | `73.6 / 82.0` | `3905 / 1800` | passed | strict style score |
+
+This is not a #40 acceptance pass yet, but it confirms the pipeline now progresses beyond the prior format-validation failure. The remaining failure is style calibration for Cloudia/Zenn, not Tailnet transport or Zenn syntax.

@@ -218,14 +218,14 @@ Current implementation status as of 2026-05-03:
 - The interview question set was simplified before the next Evo X2 run ([#66](https://github.com/terisuke/note_maker/issues/66)): broad editorial questions are now split into smaller plain-Japanese prompts, medium-specific prompts cover note/Zenn/Qiita/Cor blog needs, and optional questions can be advanced as `未定`. Validation is recorded in [Issue 66 plain brief questions validation](../validation/issue-66-plain-brief-questions-2026-05-03.md).
 - Style analysis is now persona/format-aware ([#68](https://github.com/terisuke/note_maker/issues/68)): the web UI shows a general `文体ソース` selector instead of `Noteユーザー名`, defaults it to note/Zenn/Qiita/Cor GitHub Markdown based on the selected mode, and makes persona presets include output-format notes. Validation is recorded in [Issue 68 media-aware style source validation](../validation/issue-68-media-aware-style-source-2026-05-03.md).
 - The 2026-05-03 full Tailnet Evo X2 media-matrix run proved that the runtime path works but also proved that the current scenario is not sufficient as an interview-template acceptance test: only `terisuke_note_essay` passed, Cor blog failed on assistant preamble leakage, Zenn/Qiita failed on cross-format notation leakage, and homepage failed long-form gates despite being a short HTML section. Runtime stabilization is therefore decomposed under epic [#40](https://github.com/terisuke/note_maker/issues/40) into [#70](https://github.com/terisuke/note_maker/issues/70) template/brief scenario coverage, [#71](https://github.com/terisuke/note_maker/issues/71) failed draft artifacts, [#72](https://github.com/terisuke/note_maker/issues/72) bounded format repair, [#73](https://github.com/terisuke/note_maker/issues/73) output-format-specific gates, and [#74](https://github.com/terisuke/note_maker/issues/74) staged Evo X2 reruns.
+- The #70-#73 prerequisite slice is now in place for #74: interview-template coverage exists, failed draft artifacts are preserved, format-only failures can be repaired once without relaxing validators, and scenario gates are split by output format. The first staged #74 Tailnet rerun used `cloudia_zenn_tutorial` and moved past the original failure class but failed strict style (`73.6 / 82.0`). The current cut fixes the reliability gap behind that score by generating case-specific style profile/guide artifacts, passing them into live runs, rejecting profile/guide/brief mismatches, making final verification block `scenario_passed`, enforcing structural signals, and exposing UI `quality_gate` details. The bounded rerun now passes the Zenn proof: `cloudia_zenn_tutorial` scored `88.1 / 82.0`, generated `5040 / 1800` runes, passed lightweight verification, and used the Tailnet endpoint `http://evo-x2.tailb30e58.ts.net/v1`. Validation is recorded in [Issue 74 staged Evo X2 rerun](../validation/issue-74-staged-evo-x2-rerun-2026-05-03.md).
 
 Near-term execution order:
 
-1. Add an interview-template scenario ([#70](https://github.com/terisuke/note_maker/issues/70)) before spending more Evo X2 runtime. It must prove that the simplified questions are small, medium-specific, and able to produce distinct `ArticleBrief` outputs for note, Cor blog, Zenn, Qiita, and homepage.
-2. Make failed generation diagnosable ([#71](https://github.com/terisuke/note_maker/issues/71)) and recoverable when the issue is format-only ([#72](https://github.com/terisuke/note_maker/issues/72)).
-3. Split scenario gates by output format ([#73](https://github.com/terisuke/note_maker/issues/73)) so homepage HTML is not judged as a long article while note/Zenn/Qiita/Cor blog remain strict.
-4. Re-run Evo X2 in stages ([#74](https://github.com/terisuke/note_maker/issues/74)): template scenario, offline media matrix, one previously failing live case, then the full note/Qiita/Zenn/Cor blog comparison.
-5. Continue Phase C2/C3 ([#27](https://github.com/terisuke/note_maker/issues/27), [#28](https://github.com/terisuke/note_maker/issues/28)) and Browser E2E ([#13](https://github.com/terisuke/note_maker/issues/13)) in parallel where write scopes do not conflict.
+1. Run one adjacent Cloudia technical case (`cloudia_qiita_how_to`) to check that the Cloudia/Zenn calibration and case-specific style artifacts do not leak Zenn-only notation into Qiita.
+2. If Qiita passes, run the full note/Qiita/Zenn/Cor blog comparison under [#74](https://github.com/terisuke/note_maker/issues/74), excluding homepage from the #40 closure gate while keeping it as a separate format check.
+3. Close [#40](https://github.com/terisuke/note_maker/issues/40) only after the full live matrix records primary/fallback endpoint, per-phase models, elapsed time, runes, style score, final verification, structural signals, `quality_gate`, and artifact paths for each publishing target, with no runtime, format-validation, final-verification, strict style-gate, or structural-signal failures.
+4. Continue Phase C2/C3 ([#27](https://github.com/terisuke/note_maker/issues/27), [#28](https://github.com/terisuke/note_maker/issues/28)) and Browser E2E ([#13](https://github.com/terisuke/note_maker/issues/13)) in parallel; they are product-readiness work, not prerequisites for closing #40.

+| Layer | Result |
+|---|---|
+| Tailnet runtime | passed: Evo X2 OpenAI-compatible endpoint responded and streamed metrics |
+| Format validation | passed: generated Markdown was accepted as Zenn output |
+| Length gate | passed: `3905` runes against `1800` minimum |
+| Final verification | passed with `gemma4:latest` |
+| Strict style gate | failed: `73.6 / 82.0` |
 
-| Order | Issue | Purpose | Done when |
-|---:|---|---|---|
-| 1 | [#70](https://github.com/terisuke/note_maker/issues/70) | Add an interview-template scenario | note/Cor blog/Zenn/Qiita/homepage questions and generated briefs differ by mode and remain small enough to answer |
-| 2 | [#71](https://github.com/terisuke/note_maker/issues/71) | Preserve failed draft artifacts | unusable drafts still write raw output, failure JSON, elapsed time, endpoint, and model |
-| 3 | [#72](https://github.com/terisuke/note_maker/issues/72) | Add bounded format repair | preamble leakage and Zenn/Qiita notation leakage get one strict repair retry without relaxing validators |
-| 4 | [#73](https://github.com/terisuke/note_maker/issues/73) | Split scenario gates by output format | homepage uses short HTML gates while long-form media keep strict length/style gates |
-| 5 | [#74](https://github.com/terisuke/note_maker/issues/74) | Re-run staged Evo X2 validation | one previously failing medium passes first, then the full note/Qiita/Zenn/Cor blog live matrix is rerun |
+The current cut fixed the evaluation reliability gap before trusting that score:
+
+- `cmd/scenario/media_matrix` now emits case-specific style `profile.json` and `guide.json`.
+- `cmd/scenario/live_media_matrix` passes those artifacts into `cmd/scenario/draft_generation`.
+- Draft generation rejects profile/guide/brief style-profile mismatches.
+- Final verification failure now blocks `scenario_passed`.
+- Structural signals are enforced, not only reported.
+- The web response includes `quality_gate` details so failed scores keep the draft visible.
+
+The bounded Zenn proof now passes:
+
+| Case | Seconds | First chunk | Chunks | Score / min | Runes / min | Verification |
+|---|---:|---:|---:|---:|---:|---|
+| `cloudia_zenn_tutorial` | `741.93` | `86456ms` | `2205` | `88.1 / 82.0` | `5040 / 1800` | passed |
+
+The remaining #74 work is not another Zenn-only calibration pass. It is the adjacent `cloudia_qiita_how_to` proof and then the full publishing-target matrix.

-Lanes A, B, and C can run in parallel if their write scopes stay separate. Lane D/E can continue in parallel when they do not need the same frontend files.
+Lane A should land before Lane B spends full live Evo X2 time. Lane D/E can continue in parallel when they do not need the same frontend files.
 
 ## Recommended order
 
-1. Implement #70 first. This proves the revised questions and generated briefs before any more expensive live draft runs.
-2. Implement #71/#72/#73 in parallel where possible. These directly address the failures observed on 2026-05-03.
-3. Run one bounded Evo X2 live case from a previously failing medium, not the already-passing note case.
-4. Start or continue #27/#28 so expensive live outputs can be viewed and reused from the web app.
-5. Run the full note/Qiita/Zenn/company-blog matrix under #74, then update #40 with the aggregate.
-6. Keep #36/#45 as fallback/runtime P2 work and #15 as packaging after persistence/history are usable.
+1. Run `cloudia_qiita_how_to` as the adjacent Cloudia technical proof. It should keep the improved Cloudia voice while preserving Qiita-specific notation.
+2. Run the full note/Qiita/Zenn/company-blog matrix under #74 and update #40 with the aggregate JSON/Markdown plus artifact paths.
+3. Close #40 only when every publishing target records endpoint, phase models, elapsed time, runes, style score, structural signals, final verification, `quality_gate`, and artifacts with no runtime, format-validation, final-verification, structural-signal, or strict style-gate failures. Homepage can remain a separate format check and is not part of the #40 closure gate.
+4. Continue #27/#28 and #13 in parallel as product-readiness work. Keep #36/#45 as fallback/runtime P2 work and #15 as packaging after persistence/history are usable.
 
 ## Why not run the full Evo X2 matrix now?
 
-The source and prompt matrix is ready, but full Evo X2 draft generation is expensive and can take 20+ minutes per run. The 2026-05-03 full run also showed that draft-only evaluation can miss whether interview templates are actually usable. The better sequence is to prove the question-to-brief layer first, preserve failed outputs, repair recoverable format mistakes, then use #40/#74 to evaluate one varied failing slice before the full comparison table.
+The source, prompt, artifact, repair, and gate layers are ready, but full Evo X2 draft generation is expensive and can take 20+ minutes per run. The Zenn proof now passes, so the next useful spend is the adjacent Qiita case to catch cross-format notation regression before the full #40 run.

+Issue #74 should remain open. The blocker is now specifically **Cloudia/Zenn style calibration**, not runtime, format, artifact capture, repair, length, or final verification.
+
+The next implementation work should use the preserved draft and evaluation artifacts to tune Cloudia/Zenn style guidance or scoring calibration before spending a full Evo X2 matrix run. The calibration must keep the Zenn validator strict: no assistant preamble, valid Zenn frontmatter, Zenn-only notation where applicable, and no Qiita notation leakage.

+- live media-matrix runs pass those case-specific artifacts to `draft_generation`,

+## Next proof sequence
+
+1. Run `cloudia_qiita_how_to` next to verify that the Cloudia voice improvement does not introduce Zenn-specific notation into Qiita.
+2. If both Cloudia technical cases pass, run the full live publishing-target matrix for note, Qiita, Zenn, and Cor blog.

+## #40 closure condition
+
+Issue #40 can close only after the full live matrix records endpoint, per-phase models, elapsed seconds, generated runes, style score, final verification result, and artifact paths for every publishing target, with:
+
+- no runtime endpoint failure,
+- no output-format validation failure,
+- no final-verification failure,
+- no strict style-gate failure,
+- no structural-signal failure,
+- no style profile/guide/brief mismatch,
+- no missing failed-or-successful draft artifacts.
+
+The homepage section case can remain as a separate format check, but it is not part of the #40 publishing-target closure gate.

@@ -218,14 +218,13 @@ Current implementation status as of 2026-05-03:
 - The interview question set was simplified before the next Evo X2 run ([#66](https://github.com/terisuke/note_maker/issues/66)): broad editorial questions are now split into smaller plain-Japanese prompts, medium-specific prompts cover note/Zenn/Qiita/Cor blog needs, and optional questions can be advanced as `未定`. Validation is recorded in [Issue 66 plain brief questions validation](../validation/issue-66-plain-brief-questions-2026-05-03.md).
 - Style analysis is now persona/format-aware ([#68](https://github.com/terisuke/note_maker/issues/68)): the web UI shows a general `文体ソース` selector instead of `Noteユーザー名`, defaults it to note/Zenn/Qiita/Cor GitHub Markdown based on the selected mode, and makes persona presets include output-format notes. Validation is recorded in [Issue 68 media-aware style source validation](../validation/issue-68-media-aware-style-source-2026-05-03.md).
 - The 2026-05-03 full Tailnet Evo X2 media-matrix run proved that the runtime path works but also proved that the current scenario is not sufficient as an interview-template acceptance test: only `terisuke_note_essay` passed, Cor blog failed on assistant preamble leakage, Zenn/Qiita failed on cross-format notation leakage, and homepage failed long-form gates despite being a short HTML section. Runtime stabilization is therefore decomposed under epic [#40](https://github.com/terisuke/note_maker/issues/40) into [#70](https://github.com/terisuke/note_maker/issues/70) template/brief scenario coverage, [#71](https://github.com/terisuke/note_maker/issues/71) failed draft artifacts, [#72](https://github.com/terisuke/note_maker/issues/72) bounded format repair, [#73](https://github.com/terisuke/note_maker/issues/73) output-format-specific gates, and [#74](https://github.com/terisuke/note_maker/issues/74) staged Evo X2 reruns.
-- The #70-#73 prerequisite slice is now in place for #74: interview-template coverage exists, failed draft artifacts are preserved, format-only failures can be repaired once without relaxing validators, and scenario gates are split by output format. The first staged #74 Tailnet rerun used `cloudia_zenn_tutorial` and moved past the original failure class but failed strict style (`73.6 / 82.0`). The current cut fixes the reliability gap behind that score by generating case-specific style profile/guide artifacts, passing them into live runs, rejecting profile/guide/brief mismatches, making final verification block `scenario_passed`, enforcing structural signals, and exposing UI `quality_gate` details. The bounded rerun now passes the Zenn proof: `cloudia_zenn_tutorial` scored `88.1 / 82.0`, generated `5040 / 1800` runes, passed lightweight verification, and used the Tailnet endpoint `http://evo-x2.tailb30e58.ts.net/v1`. Validation is recorded in [Issue 74 staged Evo X2 rerun](../validation/issue-74-staged-evo-x2-rerun-2026-05-03.md).

Both used the Tailnet endpoint `http://evo-x2.tailb30e58.ts.net/v1` and passed lightweight verification. Validation is recorded in [Issue 74 staged Evo X2 rerun](../validation/issue-74-staged-evo-x2-rerun-2026-05-03.md).

-2. Run the full note/Qiita/Zenn/company-blog matrix under #74 and update #40 with the aggregate JSON/Markdown plus artifact paths.
-3. Close #40 only when every publishing target records endpoint, phase models, elapsed time, runes, style score, structural signals, final verification, `quality_gate`, and artifacts with no runtime, format-validation, final-verification, structural-signal, or strict style-gate failures.

+## Adjacent Qiita proof
+
+After the Zenn proof passed, the next bounded run checked the adjacent Cloudia technical target: Qiita.
+
+Purpose:
+
+- Verify that the Cloudia style calibration generalizes beyond Zenn.
+- Confirm that Qiita-specific format and structural gates remain strict.
+- Catch cross-format regression, especially Zenn-only notation leaking into Qiita as an actual block.
+
+Command:
+

+```
+
+Runtime:
+
+- Endpoint: `http://evo-x2.tailb30e58.ts.net/v1`
+- Draft model: `gemma4:31b`
+- Verify model: `gemma4:latest`
+- Transport: Tailscale VPN / OpenAI-compatible API

+Result:
+
+| Case | Status | Seconds | First chunk | Chunks | Score / min | Runes / min | Verification |

+- Aggregate: `tmp/media_matrix/live/aggregate.json`
+- Report: `tmp/media_matrix/live/aggregate.md`
+- Draft: `tmp/media_matrix/live/cloudia_qiita_how_to/draft.md`
+- Evaluation: `tmp/media_matrix/live/cloudia_qiita_how_to/evaluation.json`
+- Verification: `tmp/media_matrix/live/cloudia_qiita_how_to/verification.json`
+- Style profile: `tmp/media_matrix/styles/cloudia_qiita_how_to/profile.json`
+- Style guide: `tmp/media_matrix/styles/cloudia_qiita_how_to/guide.json`
+
+Interpretation:
+
+- The Tailnet path still works for the adjacent Cloudia technical case.
+- The Qiita format validator accepted the article.
+- Required Qiita structural signals were present: frontmatter `title:`, `:::note`, `diff_` code fence, and `## ` headings.
+- The draft used Qiita's `diff_go` style rather than Zenn's `diff go` style.
+- Zenn `:::message` appeared only as explanatory inline/table text, not as an actual block.
+- The rune gate passed.
+- Lightweight final verification passed.
+- The strict style gate passed: `83.7`, above the Qiita gate `82.0`.
+
+The two bounded Cloudia technical proofs now both pass. The next useful Evo X2 spend is the full publishing-target matrix.

@@ -218,13 +218,15 @@ Current implementation status as of 2026-05-03:
 - The interview question set was simplified before the next Evo X2 run ([#66](https://github.com/terisuke/note_maker/issues/66)): broad editorial questions are now split into smaller plain-Japanese prompts, medium-specific prompts cover note/Zenn/Qiita/Cor blog needs, and optional questions can be advanced as `未定`. Validation is recorded in [Issue 66 plain brief questions validation](../validation/issue-66-plain-brief-questions-2026-05-03.md).
 - Style analysis is now persona/format-aware ([#68](https://github.com/terisuke/note_maker/issues/68)): the web UI shows a general `文体ソース` selector instead of `Noteユーザー名`, defaults it to note/Zenn/Qiita/Cor GitHub Markdown based on the selected mode, and makes persona presets include output-format notes. Validation is recorded in [Issue 68 media-aware style source validation](../validation/issue-68-media-aware-style-source-2026-05-03.md).
 - The 2026-05-03 full Tailnet Evo X2 media-matrix run proved that the runtime path works but also proved that the current scenario is not sufficient as an interview-template acceptance test: only `terisuke_note_essay` passed, Cor blog failed on assistant preamble leakage, Zenn/Qiita failed on cross-format notation leakage, and homepage failed long-form gates despite being a short HTML section. Runtime stabilization is therefore decomposed under epic [#40](https://github.com/terisuke/note_maker/issues/40) into [#70](https://github.com/terisuke/note_maker/issues/70) template/brief scenario coverage, [#71](https://github.com/terisuke/note_maker/issues/71) failed draft artifacts, [#72](https://github.com/terisuke/note_maker/issues/72) bounded format repair, [#73](https://github.com/terisuke/note_maker/issues/73) output-format-specific gates, and [#74](https://github.com/terisuke/note_maker/issues/74) staged Evo X2 reruns.
+- The follow-up #74 validation completed the current publishing-target acceptance scope. On 2026-05-03, the full Tailnet Evo X2 matrix passed all five article targets: note, two Cor.inc company-blog modes, Zenn, and Qiita. The run used Evo X2 Ollama primary at `http://evo-x2.tailb30e58.ts.net/v1`, `gemma4:31b` for draft generation, and `gemma4:latest` for lightweight final verification. Results are recorded in [Issue #74 staged Evo X2 rerun](../validation/issue-74-staged-evo-x2-rerun-2026-05-03.md) and `tmp/media_matrix/live/aggregate.{json,md}`. Summary: `5/5` passed, average `122.01s`, average style score `86.0`, average `3742` runes, all final verification and structural gates passed.
+- The #74 pass required additional hardening that is now part of the architecture: frontmatter preamble/fence normalization, recoverable frontmatter repair, bounded repair/revision/final-verification calls, case-specific style profiles, final verifier format-guide grounding, best-attempt selection across retries, and explicit quality-gate aggregate output.
 - The #70-#73 prerequisite slice is now in place for #74: interview-template coverage exists, failed draft artifacts are preserved, format-only failures can be repaired once without relaxing validators, and scenario gates are split by output format. The first staged #74 Tailnet rerun used `cloudia_zenn_tutorial` and moved past the original failure class but failed strict style (`73.6 / 82.0`). The current cut fixes the reliability gap behind that score by generating case-specific style profile/guide artifacts, passing them into live runs, rejecting profile/guide/brief mismatches, making final verification block `scenario_passed`, enforcing structural signals, and exposing UI `quality_gate` details. The bounded reruns now pass both Cloudia technical proofs: `cloudia_zenn_tutorial` scored `88.1 / 82.0` with `5040 / 1800` runes, and `cloudia_qiita_how_to` scored `83.7 / 82.0` with `3318 / 1400` runes. Both used the Tailnet endpoint `http://evo-x2.tailb30e58.ts.net/v1` and passed lightweight verification. Validation is recorded in [Issue 74 staged Evo X2 rerun](../validation/issue-74-staged-evo-x2-rerun-2026-05-03.md).
 
 Near-term execution order:

+Aggregate:
+
+- `5/5` publishing-target rows passed.
+- Average seconds: `122.01`.
+- Average score: `86.0`.
+- Average runes: `3742`.
+- Runtime: `http://evo-x2.tailb30e58.ts.net/v1 / gemma4:31b`.
+- Artifacts: `tmp/media_matrix/live/aggregate.json`, `tmp/media_matrix/live/aggregate.md`.
+
+Acceptance interpretation:
+
+- Offline matrix and live draft phases now agree on case-specific profile/guide/brief artifacts.
+- Each live row records endpoint/model, elapsed seconds, first chunk, chunks, style score, runes, final verification, structural gates, and `quality_gate`.
+- Note, Cor blog, Zenn, and Qiita all pass their strict long-form gates.
+- Homepage remains a separate short HTML section check and is not part of this #40 closure gate.

+- `GET /api/author-style` — saved writing style-guide list for picker UIs.
+- `GET /api/brief-sessions` — saved interview session summaries.

 ## Testing Strategy
 
 - Unit tests added per format validator, per persona seed, per fetcher.
@@ -212,6 +221,7 @@ Current implementation status as of 2026-05-03:
 - Phase B2/B3/B4 are implemented: historical source acquisition works for note, Zenn, Qiita, Cor RSS, and Cor GitHub Markdown; all five formats have prompt fragments, embedded guides, and validators; `terisuke` and `cloudia` ship as distinct seed personas. Validation is recorded in [Issue 22 source fetcher validation](../validation/issue-22-source-fetchers-2026-05-02.md) and [Issue 23/24 format and persona seed validation](../validation/issue-23-24-format-persona-seed-2026-05-02.md).
 - Phase B5 is implemented: fixed interview questions are composed server-side by `persona_id × output_format_id`, Cloudia technical modes include extra viewpoint/context prompts, the frontend reads `GET /api/brief-sessions/templates`, and `cmd/scenario/media_matrix` produces a six-case cross-media evaluation matrix for note, Cor blog, Zenn, Qiita, and homepage output ([#25](https://github.com/terisuke/note_maker/issues/25)).
 - Phase C1 is implemented and merged: `internal/infrastructure/repository/sqlite` adds migrations and storage for author styles, sessions, briefs, projects, articles, source snapshots, draft versions, final verification, and section-regeneration versions. The JSON store remains the compatibility path, while storage mode can now be inspected and switched from the web settings UI unless environment variables lock it ([#26](https://github.com/terisuke/note_maker/issues/26), [#61](https://github.com/terisuke/note_maker/issues/61)).
+- Phase C2/C3 has an implemented first product cut for workflow history and readable artifacts ([#27](https://github.com/terisuke/note_maker/issues/27), [#28](https://github.com/terisuke/note_maker/issues/28)): the web app now exposes reusable history through `GET /api/history` and `GET /api/workflow/artifacts`, plus focused read endpoints `GET /api/author-style`, `GET /api/brief-sessions`, `GET /api/briefs`, and `GET /api/briefs/{id}`. The memory and SQLite stores both expose `ListAuthorStyles`, `ListSessions`, and `ListBriefs`; SQLite also gained `ListProjects` and `ListArticlesByProject` for the richer #26 schema. The UI adds `履歴から再開`, saved style-guide/session pickers, human-readable style-guide cards, and human-readable article-brief cards while keeping raw Markdown/JSON details available. Validation is recorded in [Issue 27/28 history and artifact UI/API validation](../validation/issue-27-28-history-artifacts-2026-05-03.md).
 - Phase D1 is implemented and merged: handler tests now cover template selection, edit/fork errors, SSE follow-up and draft paths, completed-session draft fallback, regenerate-section context recovery, Analyze/Generate compatibility handlers, and SQLite driver selection. `go test ./internal/handlers -cover` reports 80%+ statement coverage ([#29](https://github.com/terisuke/note_maker/issues/29)).
 - Runtime runner support is implemented and merged: `cmd/scenario/live_media_matrix` reads the offline matrix, emits planned aggregate JSON/Markdown by default, and executes live Evo X2 draft runs only when `RUN_LIVE_MEDIA_MATRIX=1` or `make scenario-media-matrix-live` is used ([#57](https://github.com/terisuke/note_maker/issues/57)).
 - The 2026-05-03 browser 500 analysis showed an implementation drift: plain web-app startup still defaulted to workstation-local `127.0.0.1:8081`, while this ADR requires Evo X2 Tailnet as primary. Issue [#63](https://github.com/terisuke/note_maker/issues/63) restores the default order to Evo X2 Ollama over Tailnet → Evo X2 llama.cpp → workstation-local llama.cpp and makes the UI show the actual endpoint/model reported by SSE.

+# Issue 27/28 History And Artifact API Cut
+
+Date: 2026-05-03
+Branch: `codex/issue27-28-history-artifacts`
+
+## Purpose
+
+This cut makes persisted workflow memory visible enough for day-to-day drafting:
+
+- reuse a saved writing style guide without re-fetching sources,
+- reopen a saved interview session,
+- read completed briefs as cards instead of raw JSON,
+- keep the raw Markdown/JSON available for audit.
+
+It is intentionally smaller than the full Phase C vision in ADR 0002. Project/article/draft browsing is left as a follow-up on top of the richer SQLite schema.
+
+## Implemented Store Surface
+
+The handler-facing `workflowStoreBackend` now exposes the current reusable workflow artifacts:
+
+```go
+ListAuthorStyles() ([]authorstyle.AnalyzeResult, error)
+ListSessions() ([]brief.ArticleBriefSession, error)
+ListBriefs() (map[string]brief.ArticleBrief, error)
+```
+
+Both the JSON/memory store and SQLite store implement these methods.
+
+SQLite also gained entry-point list methods for later project history work:
+
+```go
+ListProjects() ([]ProjectRecord, error)
+ListArticlesByProject(projectID string) ([]ArticleRecord, error)
+```
+
+Those SQLite methods are not yet surfaced in the web UI.
+
+## Implemented HTTP Surface
+
+The web UI uses the combined index first:
+
+- `GET /api/workflow/artifacts`
+- `GET /api/history` as an alias
+
+Response:
+
+```json
+{
+  "style_guides": [],
+  "sessions": [],
+  "briefs": []
+}
+```
+
+Focused read endpoints are also available:
+
+- `GET /api/author-style` - saved style-guide artifacts
+- `GET /api/author-style/{id}` - existing detail endpoint by analysis/profile/guide id
+- `GET /api/brief-sessions` - saved interview session summaries
+- `GET /api/brief-sessions/{id}` - existing session detail endpoint
+- `GET /api/briefs` - completed brief artifacts
+- `GET /api/briefs/{id}` - completed brief artifact by session id
+
+## Implemented UI Surface
+
+`static/index.html` now includes a `履歴から再開` area:
+
+- persona filter for history selection,
+- saved style-guide picker,
+- saved interview-session picker,
+- refresh/open/clear controls,
+- loading, empty, and error states.
+
+`static/js/script.js` restores selected history into the existing workflow state:
+
+- selected style guide sets `profileId`, guide metadata, and style card,
+- selected session restores `sessionId`, transcript state, completed brief, persona/format mode, and draft-generation readiness,
+- selecting only a session resolves its style guide via `style_profile_id`.
+
+## Human-Readable Artifacts
+
+The UI now renders:
+
+- style guide cards with profile/guide/article metadata and parsed Markdown sections,
+- article brief cards with theme, reader, opening episode, action, must-include, context, exclusions, structure, tone, custom answers, and deep-dive answers.
+
+Raw Markdown and JSON are still available behind disclosure controls. This keeps review/debug data accessible without making it the default user experience.
+
+## Tests
+
+Added:
+
+- `internal/handlers/workflow_history_test.go`
+- `cmd/server/main_test.go`
+- `static/history_ui_test.go`
+
+Validation commands:
+
+```sh
+node --check static/js/script.js
+go test ./...
+git diff --check
+```
+
+## Remaining Phase C Work
+
+Not included in this cut:
+
+- add-persona authoring UI,
+- edit persistence beyond the existing fork-on-edit/session/brief save path,
+- project/article/draft history browsing,
+- draft version and section-regeneration artifact browsing,
+- browser E2E for the new history flow under Issue #13.

+# Issue 27/28 history and artifact UI/API validation
+
+Date: 2026-05-03
+Branch: `codex/issue27-28-history-artifacts`
+
+## Scope
+
+This validation covers:
+
+- [#27](https://github.com/terisuke/note_maker/issues/27) first saved-history picker cut.
+- [#28](https://github.com/terisuke/note_maker/issues/28) first human-readable style-guide and brief artifact card cut.
+
+It deliberately does not claim completion for add-persona authoring UI, broader edit persistence, project/article/draft history browsing, draft version browsing, or Browser E2E coverage.
+
+## What changed
+
+- Added history read routes:
+  - `GET /api/history`
+  - `GET /api/workflow/artifacts`
+  - `GET /api/author-style`
+  - `GET /api/brief-sessions`
+  - `GET /api/briefs`
+  - `GET /api/briefs/{id}`
+- Added store list methods:
+  - memory: `ListAuthorStyles`, `ListSessions`, `ListBriefs`
+  - SQLite: `ListAuthorStyles`, `ListSessions`, `ListBriefs`, `ListProjects`, `ListArticlesByProject`
+- Added the web UI `履歴から再開` section with saved style-guide/session pickers.
+- Added readable style-guide and article-brief cards while keeping raw Markdown/JSON disclosures.
+- Added focused handler and static UI contract tests.
+
+## API Contract
+
+`GET /api/workflow/artifacts` and `GET /api/history` return one reusable index:
+
+```json
+{
+  "style_guides": [],
+  "sessions": [],
+  "briefs": []
+}
+```
+
+The UI then opens details through existing or focused endpoints:
+
+- style guide detail: `GET /api/author-style/{id}`
+- session detail: `GET /api/brief-sessions/{id}`
+- brief detail: `GET /api/briefs/{id}`
+
+## Verification
+
+Command:
+
+```sh
+go test ./internal/handlers ./static
+```
+
+Result:
+
+```text
+ok  	github.com/teradakousuke/note_maker/internal/handlers	(cached)
+ok  	github.com/teradakousuke/note_maker/static	(cached)
+```
+
+## Acceptance Status
+
+- Saved style guides can be listed for picker UIs: done.
+- Saved interview sessions can be listed with completion and brief availability metadata: done.
+- Completed briefs can be listed and retrieved by session id: done.
+- Combined workflow artifact index returns style guides, sessions, and briefs: done.
+- UI includes `履歴から再開`, refresh/open/clear controls, saved style/session selects, and status messaging: done.
+- Style guide is rendered as a readable card and raw Markdown remains available: done.
+- Article brief is rendered as a readable card and raw JSON remains available: done.
+
+## Remaining Work
+
+- Add-persona authoring UI is still unimplemented.
+- Broader edit persistence beyond the existing fork-on-edit/session save flow is still unimplemented.
+- Project/article/draft history browsing from SQLite remains unimplemented in the UI.
+- Browser E2E coverage for the new history picker and cards remains under [#13](https://github.com/terisuke/note_maker/issues/13).

 - Phase B5 is implemented: fixed interview questions are composed server-side by `persona_id × output_format_id`, Cloudia technical modes include extra viewpoint/context prompts, the frontend reads `GET /api/brief-sessions/templates`, and `cmd/scenario/media_matrix` produces a six-case cross-media evaluation matrix for note, Cor blog, Zenn, Qiita, and homepage output ([#25](https://github.com/terisuke/note_maker/issues/25)).
 - Phase C1 is implemented and merged: `internal/infrastructure/repository/sqlite` adds migrations and storage for author styles, sessions, briefs, projects, articles, source snapshots, draft versions, final verification, and section-regeneration versions. The JSON store remains the compatibility path, while storage mode can now be inspected and switched from the web settings UI unless environment variables lock it ([#26](https://github.com/terisuke/note_maker/issues/26), [#61](https://github.com/terisuke/note_maker/issues/61)).
 - Phase C2/C3 has an implemented first product cut for workflow history and readable artifacts ([#27](https://github.com/terisuke/note_maker/issues/27), [#28](https://github.com/terisuke/note_maker/issues/28)): the web app now exposes reusable history through `GET /api/history` and `GET /api/workflow/artifacts`, plus focused read endpoints `GET /api/author-style`, `GET /api/brief-sessions`, `GET /api/briefs`, and `GET /api/briefs/{id}`. The memory and SQLite stores both expose `ListAuthorStyles`, `ListSessions`, and `ListBriefs`; SQLite also gained `ListProjects` and `ListArticlesByProject` for the richer #26 schema. The UI adds `履歴から再開`, saved style-guide/session pickers, human-readable style-guide cards, and human-readable article-brief cards while keeping raw Markdown/JSON details available. Validation is recorded in [Issue 27/28 history and artifact UI/API validation](../validation/issue-27-28-history-artifacts-2026-05-03.md).
+- The #13 follow-up has browser-adjacent contract coverage for the static HTML, script selectors, persistence hooks, workflow read routes, and artifact-card structure. It does not close #13: Playwright or equivalent real browser coverage is still required for persona/format switching, history open, readable cards, edit/fork, streaming/cancel, regenerate-section, and localStorage migration. Validation is recorded in [Issue #13 Browser Contract Coverage](../validation/issue-13-browser-contract-coverage-2026-05-03.md).
+- A Phase C project/article/draft history follow-up now builds on the #26 SQLite schema: `GET /api/workflow/artifacts` includes project/article/draft summaries when SQLite is active, focused read routes expose project/article/draft details, and the history UI renders project, article, brief, current draft, draft versions, and source snapshot cards. The handler/server/static tests are green, but until the browser flow is covered by #13, the canonical completed Phase C closure claim remains separate from full browser E2E.
 - Phase D1 is implemented and merged: handler tests now cover template selection, edit/fork errors, SSE follow-up and draft paths, completed-session draft fallback, regenerate-section context recovery, Analyze/Generate compatibility handlers, and SQLite driver selection. `go test ./internal/handlers -cover` reports 80%+ statement coverage ([#29](https://github.com/terisuke/note_maker/issues/29)).
 - Runtime runner support is implemented and merged: `cmd/scenario/live_media_matrix` reads the offline matrix, emits planned aggregate JSON/Markdown by default, and executes live Evo X2 draft runs only when `RUN_LIVE_MEDIA_MATRIX=1` or `make scenario-media-matrix-live` is used ([#57](https://github.com/terisuke/note_maker/issues/57)).
 - The 2026-05-03 browser 500 analysis showed an implementation drift: plain web-app startup still defaulted to workstation-local `127.0.0.1:8081`, while this ADR requires Evo X2 Tailnet as primary. Issue [#63](https://github.com/terisuke/note_maker/issues/63) restores the default order to Evo X2 Ollama over Tailnet → Evo X2 llama.cpp → workstation-local llama.cpp and makes the UI show the actual endpoint/model reported by SSE.

+# Issue #13 Browser Contract Coverage
+
+Date: 2026-05-03
+Branch: `codex/phase-c-history-e2e`
+
+## Scope
+
+Added practical browser-adjacent coverage that remains part of `go test ./...`:
+
+- Static HTML contract checks for model selectors, question controls, history controls, and artifact card containers.
+- Static JavaScript contract checks for model config persistence, custom question add/edit/delete/reset behavior, history loading/opening flow, and readable artifact-card rendering.
+- `httptest` coverage that the server route table exposes workflow read APIs and serves the browser entrypoint plus the production script.
+
+This validates contract shape, not user behavior in a real browser. Issue [#13](https://github.com/terisuke/note_maker/issues/13) stays open until Playwright or equivalent browser E2E covers the actual flows.
+
+## Why Not Playwright Yet
+
+The current frontend script is a single `DOMContentLoaded` closure with no importable UI functions. A Playwright suite is still the right next step, but adding it now would require a heavier test harness with stubbed API routes and browser setup that is not yet present in this repository.
+
+This pass keeps CI friction low by expanding Go tests first. The contract tests intentionally lock DOM IDs, event bindings, persistence calls, fetch endpoints, and card-rendering structure so a later Playwright suite has stable selectors and scenarios to target.
+
+## Next Playwright Path
+
+Recommended scenarios when browser E2E is introduced:
+
+1. Stub `/api/models`, `/api/personas`, `/api/formats`, `/api/brief-sessions/templates`, and `/api/workflow/artifacts`.
+2. Assert all four model selectors populate from `/api/models`, save into `localStorage["note-maker-config-v1"]`, and restore on reload.
+3. Add a custom question, edit it, delete it, reload with saved custom questions, and reset back to template-only state.
+4. Select saved style/session history, assert the open button enables, clear disables it, and opening fetches `/api/author-style/{id}` or `/api/brief-sessions/{id}` as needed.
+5. Assert non-empty style and brief cards render `.artifact-card-header`, `.artifact-meta`, and `.artifact-section`, while raw Markdown/JSON previews remain populated.
+
+## Commands
+
+```sh
+go test ./static ./cmd/server
+go test ./...
+```
+
+## Review Result
+
+Commands passed after aligning the parallel history test fixture with the selected output-format validator:
+
+```sh
+go test ./cmd/server ./internal/handlers ./static
+go test ./internal/handlers ./static
+go test ./static ./cmd/server
+go test ./...
+node --check static/js/script.js
+git diff --check
+```
+
+This browser-contract document is still a validation checkpoint, not a close signal for #13. The next cut should add browser E2E over stubbed API responses once the project has a Playwright or equivalent harness.
+
+## Issue Policy
+
+- #13: keep open. Contract coverage is useful, but the issue asks for browser E2E.
+- #14: keep open. SQLite exists, but queryable product memory is not fully exposed.
+- #27: keep open unless the owner explicitly splits and closes the first saved-history picker cut.
+- #28: keep open unless the owner explicitly splits and closes the first readable-card cut.

@@ -222,8 +222,8 @@ Current implementation status as of 2026-05-03:
 - Phase B5 is implemented: fixed interview questions are composed server-side by `persona_id × output_format_id`, Cloudia technical modes include extra viewpoint/context prompts, the frontend reads `GET /api/brief-sessions/templates`, and `cmd/scenario/media_matrix` produces a six-case cross-media evaluation matrix for note, Cor blog, Zenn, Qiita, and homepage output ([#25](https://github.com/terisuke/note_maker/issues/25)).
 - Phase C1 is implemented and merged: `internal/infrastructure/repository/sqlite` adds migrations and storage for author styles, sessions, briefs, projects, articles, source snapshots, draft versions, final verification, and section-regeneration versions. The JSON store remains the compatibility path, while storage mode can now be inspected and switched from the web settings UI unless environment variables lock it ([#26](https://github.com/terisuke/note_maker/issues/26), [#61](https://github.com/terisuke/note_maker/issues/61)).
 - Phase C2/C3 has an implemented first product cut for workflow history and readable artifacts ([#27](https://github.com/terisuke/note_maker/issues/27), [#28](https://github.com/terisuke/note_maker/issues/28)): the web app now exposes reusable history through `GET /api/history` and `GET /api/workflow/artifacts`, plus focused read endpoints `GET /api/author-style`, `GET /api/brief-sessions`, `GET /api/briefs`, and `GET /api/briefs/{id}`. The memory and SQLite stores both expose `ListAuthorStyles`, `ListSessions`, and `ListBriefs`; SQLite also gained `ListProjects` and `ListArticlesByProject` for the richer #26 schema. The UI adds `履歴から再開`, saved style-guide/session pickers, human-readable style-guide cards, and human-readable article-brief cards while keeping raw Markdown/JSON details available. Validation is recorded in [Issue 27/28 history and artifact UI/API validation](../validation/issue-27-28-history-artifacts-2026-05-03.md).
-- The #13 follow-up has browser-adjacent contract coverage for the static HTML, script selectors, persistence hooks, workflow read routes, and artifact-card structure. It does not close #13: Playwright or equivalent real browser coverage is still required for persona/format switching, history open, readable cards, edit/fork, streaming/cancel, regenerate-section, and localStorage migration. Validation is recorded in [Issue #13 Browser Contract Coverage](../validation/issue-13-browser-contract-coverage-2026-05-03.md).
-- A Phase C project/article/draft history follow-up now builds on the #26 SQLite schema: `GET /api/workflow/artifacts` includes project/article/draft summaries when SQLite is active, focused read routes expose project/article/draft details, and the history UI renders project, article, brief, current draft, draft versions, and source snapshot cards. The handler/server/static tests are green, but until the browser flow is covered by #13, the canonical completed Phase C closure claim remains separate from full browser E2E.
+- The #13 follow-up has real browser E2E coverage: Python `pytest` plus Playwright starts the real Go server on a free localhost port, stubs application APIs in the browser, and covers model config persistence, custom question CRUD/reset, legacy localStorage migration, persona/format switching, interview start payloads, history opening/readable cards, edit/fork, streaming/cancel, and section regeneration. Validation is recorded in [Issue #13 Browser E2E Validation](../validation/issue-13-browser-e2e-2026-05-03.md).
+- A Phase C project/article/draft history follow-up now builds on the #26 SQLite schema: `GET /api/workflow/artifacts` includes project/article/draft summaries when SQLite is active, focused read routes expose project/article/draft details, and the history UI renders project, article, brief, current draft, draft versions, and source snapshot cards. Handler/server/static tests and browser E2E are green for this surface; broader Phase C product semantics remain tracked separately from #13.
 - Phase D1 is implemented and merged: handler tests now cover template selection, edit/fork errors, SSE follow-up and draft paths, completed-session draft fallback, regenerate-section context recovery, Analyze/Generate compatibility handlers, and SQLite driver selection. `go test ./internal/handlers -cover` reports 80%+ statement coverage ([#29](https://github.com/terisuke/note_maker/issues/29)).
 - Runtime runner support is implemented and merged: `cmd/scenario/live_media_matrix` reads the offline matrix, emits planned aggregate JSON/Markdown by default, and executes live Evo X2 draft runs only when `RUN_LIVE_MEDIA_MATRIX=1` or `make scenario-media-matrix-live` is used ([#57](https://github.com/terisuke/note_maker/issues/57)).
 - The 2026-05-03 browser 500 analysis showed an implementation drift: plain web-app startup still defaulted to workstation-local `127.0.0.1:8081`, while this ADR requires Evo X2 Tailnet as primary. Issue [#63](https://github.com/terisuke/note_maker/issues/63) restores the default order to Evo X2 Ollama over Tailnet → Evo X2 llama.cpp → workstation-local llama.cpp and makes the UI show the actual endpoint/model reported by SSE.

 This browser-contract document is still a validation checkpoint, not a close signal for #13. The next cut should add browser E2E over stubbed API responses once the project has a Playwright or equivalent harness.
 
+## Browser E2E Follow-up
+
+Review date: 2026-05-03 on `codex/issue13-browser-e2e`.
+
+The follow-up cut adds real browser E2E coverage using Python `pytest` plus Playwright. It starts the real Go server on a free localhost port and uses Playwright route handlers to stub `/api/*` and the external `marked` CDN script. This keeps the tests deterministic and avoids Evo X2/local LLM calls while still exercising the browser DOM, production HTML, and production JavaScript.

+# Issue #13 Browser E2E Validation
+
+Date: 2026-05-03
+Branch: `codex/issue13-browser-e2e`
+
+## Scope
+
+This cut adds real browser E2E coverage for Issue #13 using Python `pytest` plus Playwright. The tests start the real Go web server on a free localhost port and stub application API calls through Playwright route handlers, so the browser exercises the production `static/index.html` and `static/js/script.js` without connecting to Evo X2 or any local LLM.
+
+## Implementation
+
+- `tests/e2e/e2e_server.py` starts `go run ./cmd/server` on an ephemeral port with temporary workflow/config storage and LLM endpoints disabled.
+- `tests/e2e/conftest.py` provides `base_url`, `page`, and `api_stub` fixtures and replaces the external `marked` CDN script with a local browser stub.
+- `tests/e2e/test_config_questions.py` covers model selector persistence/reload restore, persona/output-format template switching, custom question add/edit/delete/reset, legacy `localStorage` migration, preset style seeding, interview start payloads, and answer SSE submission.
+- `tests/e2e/test_history_stream_regenerate.py` covers saved history opening, readable history cards, answer edit/fork, answer and draft streaming/cancel recovery, and section regeneration reject/accept.
+- Missing Playwright or browser binaries fail the E2E target instead of reporting a skipped green run.
+- `make e2e` runs the browser suite.
+
+## Validation
+
+```sh
+python3 -m pytest tests/e2e -q
+go test ./...
+git diff --check
+```
+
+Result from the final local review:
+
+```text

+8 passed in 5.80s
+go test ./... passed
+git diff --check passed
+```
+
+## Closure Decision
+
+Issue #13 can close with this cut. The original acceptance and later comments are covered by real browser tests:
+
+- model dropdown population and persisted phase-model choices;
+- custom question add/edit/delete/reset;
+- legacy `questions` localStorage migration to `customQuestions`;
+- persona and output-format switching with template reloads;
+- starting an interview with custom questions in the `/api/brief-sessions` payload;
+- answer SSE submission and cancel recovery;
+- saved history style/session/project/article/draft opening and readable cards;
+- edit-and-fork endpoint behavior;
+- streaming draft UI, cancellation, failed/partial state recovery surface;
+- section regeneration candidate reject and accept flow.
+
+Remaining work after this cut belongs to broader Phase C product scope, not #13: add-persona authoring UI, richer edit persistence/version semantics, and further project/article/draft browsing polish.

 - Phase B2/B3/B4 are implemented: historical source acquisition works for note, Zenn, Qiita, Cor RSS, and Cor GitHub Markdown; all five formats have prompt fragments, embedded guides, and validators; `terisuke` and `cloudia` ship as distinct seed personas. Validation is recorded in [Issue 22 source fetcher validation](../validation/issue-22-source-fetchers-2026-05-02.md) and [Issue 23/24 format and persona seed validation](../validation/issue-23-24-format-persona-seed-2026-05-02.md).
 - Phase B5 is implemented: fixed interview questions are composed server-side by `persona_id × output_format_id`, Cloudia technical modes include extra viewpoint/context prompts, the frontend reads `GET /api/brief-sessions/templates`, and `cmd/scenario/media_matrix` produces a six-case cross-media evaluation matrix for note, Cor blog, Zenn, Qiita, and homepage output ([#25](https://github.com/terisuke/note_maker/issues/25)).
 - Phase C1 is implemented and merged: `internal/infrastructure/repository/sqlite` adds migrations and storage for author styles, sessions, briefs, projects, articles, source snapshots, draft versions, final verification, and section-regeneration versions. The JSON store remains the compatibility path, while storage mode can now be inspected and switched from the web settings UI unless environment variables lock it ([#26](https://github.com/terisuke/note_maker/issues/26), [#61](https://github.com/terisuke/note_maker/issues/61)).

+# Next implementation cut: Phase C persona/history/card polish
 
 Date: 2026-05-03
+Branch: `codex/phase-c-persona-history-polish`
+Route: C, docs/coordination
 
-This document translates the current open issue set into the next executable implementation sequence. The end state is unchanged: run Evo X2 Tailnet scenarios for note, Qiita, Zenn, and Cor.inc company blog with different themes, tones, and target lengths, then compare runtime, score, verification, and final output quality.
+This document records the current Phase C persona/history/card polish cut. The runtime and browser-E2E gates now have validation records; this cut adds custom persona create/list and editable brief/style card persistence on top of the existing history surface.
+
+The remaining limitations are narrower: custom persona update/delete, richer persona source management, and full queryable/versioned product memory remain outside this cut.

Custom persona update/delete should be tracked separately if needed. |

 ## Recommended order
 
-1. Merge the #13 browser E2E cut and close #13 with the validation document.
-2. Split the remaining Phase C product work into explicit follow-up issues before broadening implementation: add-persona authoring UI, broader edit persistence semantics, and project/article/draft artifact browsing polish from the #26 SQLite schema.
-3. Close #74 and #40 for the current publishing-target acceptance scope after the PR lands and the issue comments link the final aggregate artifacts.
+1. Use the #13 Playwright validation as the browser baseline; do not track Phase C product gaps as browser-E2E debt.
+2. Merge this Phase C polish cut if the validation document stays green, then close #27/#28 according to the issue-owner scope decision.
+3. Keep #14 open for complete queryable product memory and decide whether custom persona update/delete or brief-version tables need separate follow-up issues.
 4. Keep #36/#45 as fallback/runtime P2 work and #15 as packaging after persistence/history are usable. Homepage remains a separate short-format check, not part of the #40 closure gate.

+At the time of the contract cut, the frontend script was a single `DOMContentLoaded` closure with no importable UI functions. A later cut added the heavier test harness with stubbed API routes and browser setup.
 
 This pass keeps CI friction low by expanding Go tests first. The contract tests intentionally lock DOM IDs, event bindings, persistence calls, fetch endpoints, and card-rendering structure so a later Playwright suite has stable selectors and scenarios to target.

+# Phase C Persona/History/Card Polish Validation
+
+Date: 2026-05-03
+Branch: `codex/phase-c-persona-history-polish`
+Route: C, docs/coordination
+Base: `develop` after PR #85 merge
+
+## Scope
+
+This validates the Phase C product polish cut for custom persona create/list and editable brief/style cards.
+
+This PR implements:
+
+- built-in plus custom persona listing through `GET /api/personas`;
+- custom persona creation through `POST /api/personas`;
+- custom persona persistence in memory and SQLite stores, including SQLite reopen coverage;
+- add-persona UI that saves, selects, reloads, and aligns the history persona selector;
+- saved style-guide and brief-session reuse through `履歴から再開`;
+- SQLite-backed project/article/draft/source-snapshot read routes and history cards when the active store supports them;
+- human-readable style-guide, brief, project, article, current-draft, draft-version, and source-snapshot cards;
+- style-guide card edit/save through `PATCH /api/author-style/{id}` / `POST /api/author-style/{id}/versions`;
+- brief card edit/save through `PATCH /api/briefs/{id}`;
+- editable draft Markdown and section-regeneration candidate accept/reject flow;
+- browser E2E baseline for #13 in `tests/e2e`.
+
+Known limitations:
+
+- custom persona update/delete is not implemented;
+- richer persona source editing is not implemented after create;
+- brief-card edits update the saved brief artifact but do not rewrite original session answers or create a separate brief-version table;
+- project/article/draft/source-snapshot cards remain read-only;
+- #14 remains open for broader queryable product memory and version/history semantics.

 Conclusion: the domain model and application services match ADR 0002 well enough to continue. The largest architectural risk is not the domain vocabulary; it is handler-led orchestration and hidden runtime configuration. The next implementation sequence should reduce those two risks before the full Evo X2 media-matrix evaluation.

-### まとめて起動する
+### アプリ風 launcher で起動する
 
-`llama-server` と Go サーバーをまとめて起動できます。
+通常利用は launcher 経由を推奨します。launcher は空いているローカルポートを選び、Evo X2 Tailnet の primary LLM health を確認し、Go サーバーをビルドして起動し、終了時に子プロセスを停止します。既定では Mac 側のローカル fallback LLM は起動しません。
 
 ```bash
-make app
+make launcher
 ```
 
-ブラウザで `http://localhost:8080` にアクセスします。終了するときは `Ctrl-C` で両方のプロセスを停止できます。
+または mise を使う場合:
+
+```bash
+mise run launcher
+```
+
+`make app` も同じ launcher を起動する alias です。
+
+起動後はブラウザが自動で開きます。終了するときは launcher を実行したターミナルで `Ctrl-C` を押します。`PORT` が使用中の場合は、既定で次の空きポートを選びます。固定ポートで失敗させたい場合は `./scripts/launcher.sh --strict-port` を使います。
+
+launcher の既定保存先:
+
+- macOS: `~/Library/Application Support/Note Maker`
+- Linux/その他: `$XDG_DATA_HOME/note-maker` または `~/.local/share/note-maker`
+
+この配下に `app_config.json`、`workflow_store.json`、`logs/`、ビルド済みサーバーバイナリを置きます。保存先を変える場合は `NOTE_MAKER_DATA_DIR=/path/to/dir make launcher` または `./scripts/launcher.sh --data-dir /path/to/dir` を指定します。
+
+Evo X2 Tailnet が到達不能な場合、既定ではアプリを起動しません。UIだけを起動したい検証時は `make launcher-status` で状態を確認し、必要に応じて `./scripts/launcher.sh --allow-degraded` を使います。ローカル `llama-server` を明示的に起動して primary として使う場合だけ、次を実行します。
+
+```bash
+make launcher-local
+```
 
 `llama-server` の場所やモデルを変える場合は `.env` の `LLAMA_SERVER`、`LLAMACPP_HF_REPO`、`LLAMACPP_HF_FILE`、`LLAMACPP_MODEL` を変更します。
 
+launcher 自体の検証:
+
+```bash
+make launcher-check
+```
+
+### 旧 dev script でまとめて起動する
+
+従来の `scripts/dev.sh` は残しています。`LLM_RUNTIME=local` を明示した検証では `llama-server` と Go サーバーをまとめて起動できます。
+
+```bash
+make dev
+```
+
+ブラウザで `http://localhost:8080` にアクセスします。終了するときは `Ctrl-C` で両方のプロセスを停止できます。
+
 ### Evo X2 の Ollama を Tailscale VPN 経由で使って起動する
 
 Evo X2 の Ollama を使う場合は、Tailscale VPN/MagicDNS 上の OpenAI互換APIを primary とし、Mac側のローカルLLMは起動しません。fallback は順番を固定します。

 このシナリオは文体分析、一問一答、深掘り、下書き生成を通し、文体スコア80点以上と一定以上の本文量を確認します。
 
+### ローカル llama.cpp fallback だけを検証する
+
+Evo X2 primary とは別に、作業端末上で既に起動済みの `llama.cpp` fallback だけを検証する場合は専用ターゲットを使います。このターゲットは Ollama や `llama-server` を起動せず、Evo X2 への fallback chain も無効化します。
+
+まず plan/report だけを作る場合:
+
+```bash
+make scenario-local-llamacpp-fallback
+```
+
+実際に draft 生成まで走らせる場合は、誤って Evo X2 primary 検証と混同しないように明示的な gate が必要です。`LOCAL_LLAMACPP_FALLBACK_BASE_URL` は loopback の OpenAI互換 `/v1` endpoint だけを受け付けます。
+
+```bash
+RUN_LOCAL_LLAMACPP_FALLBACK_SCENARIO=1 \
+LOCAL_LLAMACPP_FALLBACK_BASE_URL=http://127.0.0.1:8081/v1 \
+LOCAL_LLAMACPP_FALLBACK_MODEL=qwen3:30b-a3b \
+LOCAL_LLAMACPP_FALLBACK_LOAD_FLAGS='--host 127.0.0.1 --port 8081 --alias qwen3:30b-a3b --reasoning off ...' \
+make scenario-local-llamacpp-fallback
+```
+
+結果は `tmp/local_llamacpp_fallback/report.md` と `tmp/local_llamacpp_fallback/report.json` に記録されます。Issue #36 の合格条件は `score >= 82.0`、`keyword_overlap >= 70`、`runes >= 2800` です。記録テンプレートは `docs/validation/issue-36-local-llamacpp-fallback-template.md` です。

+  - `llama.cpp` model swapping is tracked by Issue [#45](https://github.com/terisuke/note_maker/issues/45). The current recommended implementation is a conservative systemd/profile swap for one shared fallback `llama-server` behind `/llama/v1`, with dry-run default scripts and explicit restart gates. Until live Evo X2 validation proves brief/draft quality, first-token latency, and no Ollama disruption, `llama-server` remains a fallback route rather than the primary multi-model route.
   - Direct local Ollama on `127.0.0.1:11434` must not be used as the default verification path; it is only acceptable when explicitly selected for a one-off diagnostic.
   - Scenario output must record the base URL, model, elapsed time, style score, and draft length so accidental runtime swaps are visible.

 - The follow-up #74 validation completed the current publishing-target acceptance scope. On 2026-05-03, the full Tailnet Evo X2 matrix passed all five article targets: note, two Cor.inc company-blog modes, Zenn, and Qiita. The run used Evo X2 Ollama primary at `http://evo-x2.tailb30e58.ts.net/v1`, `gemma4:31b` for draft generation, and `gemma4:latest` for lightweight final verification. Results are recorded in [Issue #74 staged Evo X2 rerun](../validation/issue-74-staged-evo-x2-rerun-2026-05-03.md) and `tmp/media_matrix/live/aggregate.{json,md}`. Summary: `5/5` passed, average `122.01s`, average style score `86.0`, average `3742` runes, all final verification and structural gates passed.
 - The #74 pass required additional hardening that is now part of the architecture: frontmatter preamble/fence normalization, recoverable frontmatter repair, bounded repair/revision/final-verification calls, case-specific style profiles, final verifier format-guide grounding, best-attempt selection across retries, and explicit quality-gate aggregate output.
 - The #70-#73 prerequisite slice is now in place for #74: interview-template coverage exists, failed draft artifacts are preserved, format-only failures can be repaired once without relaxing validators, and scenario gates are split by output format. The first staged #74 Tailnet rerun used `cloudia_zenn_tutorial` and moved past the original failure class but failed strict style (`73.6 / 82.0`). The current cut fixes the reliability gap behind that score by generating case-specific style profile/guide artifacts, passing them into live runs, rejecting profile/guide/brief mismatches, making final verification block `scenario_passed`, enforcing structural signals, and exposing UI `quality_gate` details. The bounded reruns now pass both Cloudia technical proofs: `cloudia_zenn_tutorial` scored `88.1 / 82.0` with `5040 / 1800` runes, and `cloudia_qiita_how_to` scored `83.7 / 82.0` with `3318 / 1400` runes. Both used the Tailnet endpoint `http://evo-x2.tailb30e58.ts.net/v1` and passed lightweight verification. Validation is recorded in [Issue 74 staged Evo X2 rerun](../validation/issue-74-staged-evo-x2-rerun-2026-05-03.md).
+- The #45 llama.cpp swap orchestration cut now has a documented conservative fallback strategy, dry-run default Make targets, and a gated direct `/llama/v1` brief/draft scenario target. It does not change the primary runtime decision: Ollama remains primary until the live #45 criteria prove active-profile quality and operations safety.

+# Issue #45 - Evo X2 llama.cpp model swap orchestration
+
+Issue: [#45](https://github.com/terisuke/note_maker/issues/45)
+
+## Decision
+
+Keep Evo X2 Ollama as the primary runtime. Use Evo X2 `llama-server` only as a
+single active fallback profile behind the existing Tailnet/Caddy path:
+
+```text
+primary:  http://evo-x2.tailb30e58.ts.net/v1
+fallback: http://evo-x2.tailb30e58.ts.net/llama/v1
+```
+
+Do not use llama.cpp as the primary multi-model router yet. The app needs
+phase-specific model selection for style, brief, article, draft, and verify
+calls; Ollama already supports that operational model per OpenAI-compatible
+request. The conservative llama.cpp path is an explicit service-profile swap:
+
+1. define one systemd service for the shared fallback path,
+2. keep profile env files under `/etc/note-maker/llama-cpp/`,
+3. point `/etc/note-maker/llama-cpp/active.env` at the selected profile,
+4. restart only the llama.cpp fallback service,
+5. verify `/llama/health` and `/llama/v1/models`,
+6. run brief/draft scenario validation before changing app fallback defaults.
+
+This keeps Ollama and other Evo X2 users unaffected unless they explicitly use
+the `/llama/v1` fallback endpoint during the maintenance window.
+
+## Rationale
+
+The current upstream `llama-server` documentation says `/v1/models` returns the
+loaded model and that the returned list has one element. It also documents
+`--alias` as the way to expose a custom model id. That model fits a stable
+"one active fallback alias" service better than per-phase dynamic routing.
+
+Upstream has newer router/profile work, but current issue traffic still shows
+operational risk around router mode and multiple model handling. In particular,
+a recent router-mode bug report described extra GPU memory use when loading
+models through `--models-preset` / model-directory router mode. Until Evo X2
+validation proves memory headroom and first-token latency with Ollama still
+serving primary traffic, multi-instance or router-mode llama.cpp should remain
+out of the default path.
+
+Primary sources:
+
+- `llama-server` README, `/v1/models` and `--alias`: <https://github.com/ggml-org/llama.cpp/blob/master/tools/server/README.md#openai-compatible-api-endpoints>
+- Multiple alias feature request: <https://github.com/ggml-org/llama.cpp/issues/17860>
+- Router-mode GPU memory regression report: <https://github.com/ggml-org/llama.cpp/issues/21692>
+
+## Recommended service shape
+
+Example systemd unit on Evo X2:
+
+```ini
+[Unit]
+Description=Note Maker llama.cpp fallback
+After=network-online.target
+
+[Service]
+EnvironmentFile=/etc/note-maker/llama-cpp/active.env
+ExecStart=/usr/local/bin/llama-server \
+  --model ${LLAMA_CPP_MODEL_PATH} \
+  --alias ${LLAMA_CPP_ALIAS} \
+  --host ${LLAMA_CPP_HOST} \
+  --port ${LLAMA_CPP_PORT} \
+  --ctx-size ${LLAMA_CPP_CTX_SIZE} \
+  ${LLAMA_CPP_EXTRA_ARGS}
+Restart=on-failure
+RestartSec=5
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Example profile:
+
+```bash
+LLAMA_CPP_MODEL_PATH=/srv/models/gemma-4-E2B-it-Q8_0.gguf
+LLAMA_CPP_ALIAS=gemma-4-E2B-it-Q8_0.gguf
+LLAMA_CPP_HOST=127.0.0.1
+LLAMA_CPP_PORT=18081
+LLAMA_CPP_CTX_SIZE=8192
+LLAMA_CPP_EXTRA_ARGS=--jinja
+```
+
+Caddy should continue to publish only the fallback path, for example:
+
+```text
+/llama/* -> http://127.0.0.1:18081/*
+```
+
+## Phase aliases
+
+Because one active llama.cpp model is exposed at a time, the fallback model env
+vars should all point at the active alias for validation:
+
+```bash
+EVO_X2_LLAMA_CPP_MODEL=gemma-4-E2B-it-Q8_0.gguf
+EVO_X2_LLAMA_CPP_STYLE_MODEL=gemma-4-E2B-it-Q8_0.gguf
+EVO_X2_LLAMA_CPP_BRIEF_MODEL=gemma-4-E2B-it-Q8_0.gguf
+EVO_X2_LLAMA_CPP_ARTICLE_MODEL=gemma-4-E2B-it-Q8_0.gguf
+EVO_X2_LLAMA_CPP_DRAFT_MODEL=gemma-4-E2B-it-Q8_0.gguf
+EVO_X2_LLAMA_CPP_VERIFY_MODEL=gemma-4-E2B-it-Q8_0.gguf
+```
+
+If a profile is intended only for a narrow phase, keep it out of the app's
+default fallback chain and invoke it only through explicit scenario commands.
+
+## Operations commands
+
+Inspect active primary/fallback models and the configured remote service:
+
+```bash
+make evo-x2-llama-status
+```
+
+Print the selected start/swap plan without changing Evo X2:
+
+```bash
+make evo-x2-llama-plan
+```
+
+Dry-run a start:
+
+```bash
+make evo-x2-llama-start
+```
+
+Apply a start only when the service is known to be safe:
+
+```bash
+EVO_X2_LLAMA_CPP_APPLY=1 make evo-x2-llama-start
+```
+
+Dry-run a profile swap:
+
+```bash
+EVO_X2_LLAMA_CPP_PROFILE=fallback-gemma-e2b make evo-x2-llama-swap
+```
+
+Apply a profile swap only in a maintenance window:
+
+```bash
+EVO_X2_LLAMA_CPP_APPLY=1 \
+EVO_X2_LLAMA_CPP_ALLOW_RESTART=1 \
+EVO_X2_LLAMA_CPP_PROFILE=fallback-gemma-e2b \
+make evo-x2-llama-swap
+```
+
+## Validation gate
+
+The llama.cpp fallback cannot replace Ollama until it passes the same runtime
+signals used around #18's streaming work and current full workflow scenarios:
+
+- brief interview completes against the active fallback endpoint,
+- streamed draft generation reports `first_chunk_ms` and `chunks`,
+- `scenario_passed=true`,
+- `score >= SCENARIO_MIN_STYLE_SCORE`,
+- `runes >= SCENARIO_MIN_DRAFT_RUNES`,
+- final verification passes when performed,
+- report includes `llm_base_url`, `llm_model`, `verify_model`, and elapsed time.
+
+Live validation is intentionally gated:
+
+```bash
+RUN_EVO_X2_LLAMA_CPP_SCENARIO=1 make scenario-evo-x2-llama-brief-draft
+```
+
+This command sets `LLM_BASE_URL` directly to `/llama/v1` and clears fallback
+URLs so the run cannot silently pass through Ollama.
+
+## ADR / plan alignment
+
+This strategy is consistent with ADR 0001, ADR 0002, and the implementation
+plans because it preserves the runtime order:
+
+1. Evo X2 Ollama Tailnet primary.
+2. Evo X2 llama.cpp fallback through `/llama/v1`.
+3. Workstation-local llama.cpp as last resort.
+
+It also preserves the current phase-model split. llama.cpp is not treated as a
+drop-in per-phase router because the selected conservative service shape exposes
+one active alias at a time. Any future multi-instance or router-mode approach
+must be validated as a separate operational change with memory/latency evidence
+while Ollama is still serving primary traffic.
+
+The #45 implementation therefore satisfies design/script readiness, but not
+live runtime acceptance. Keep the issue open until the pending criteria in
+`docs/validation/issue-45-llamacpp-swap-orchestration-2026-05-03.md` pass.

+# Issue 15 launcher validation
+
+Date: 2026-05-03
+
+Scope: packaging/dev launcher files only.
+
+## Implemented behavior
+
+- Added `scripts/launcher.sh` as an app-like launcher for the Go web app.
+- Defaults to Evo X2 Tailnet as the primary OpenAI-compatible LLM health path.
+- Does not start local `llama-server` unless `--local-llm`, `make launcher-local`, or `NOTE_MAKER_START_LOCAL_LLM=1` is used.
+- Selects the requested port or the next available port unless `--strict-port` is set.
+- Uses a user data directory for app config, workflow store, logs, and the built server binary.
+- Stops the managed server process on `SIGTERM`, `SIGINT`, or shell exit.
+
+## Validation
+
+```bash
+./scripts/check-launcher.sh
+```
+
+Result: passed. This ran `bash -n` for launcher-related scripts, `shellcheck` when available, the launcher shell tests, and Make dry-runs for launcher targets.
+
+```bash
+go test ./...
+```
+
+Result: passed.
+
+```bash
+make launcher-status
+```
+
+Result: passed. Evo X2 Tailnet primary was reachable at `http://evo-x2.tailb30e58.ts.net/v1/models`; Evo X2 llama.cpp fallback was reachable at `http://evo-x2.tailb30e58.ts.net/llama/v1/models`; local fallback `http://127.0.0.1:8081/v1/models` was not running and was not started.
+
+```bash
+./scripts/launcher.sh --no-open
+kill -TERM <launcher-pid>
+lsof -nP -iTCP:8080 -sTCP:LISTEN
+```
+
+Result: launcher built the server binary, started the app on `http://127.0.0.1:8080`, then stopped the managed server after `SIGTERM`; no listener remained on port 8080.
+
+## Closure status
+
+This substantially implements issue #15 with a pragmatic shell launcher. A full Tauri/Electron wrapper, app icon, signing, and installer packaging remain future packaging work, but the user-facing startup path, process lifecycle, health checks, storage defaults, and Make/mise entrypoints are in place.

+# Issue #36 local llama.cpp fallback status - 2026-05-03
+
+## Summary for Issue/PR
+
+Issue #36 is substantially implemented from the validation-tooling side, but it should not close yet because no real local llama.cpp fallback draft run was executed on available local hardware/model runtime.
+
+The new dedicated fallback validation command is in place:
+
+```sh
+make scenario-local-llamacpp-fallback
+```
+
+The live draft run is intentionally gated and requires:
+
+```sh
+RUN_LOCAL_LLAMACPP_FALLBACK_SCENARIO=1 \
+LOCAL_LLAMACPP_FALLBACK_BASE_URL=http://127.0.0.1:8081/v1 \
+LOCAL_LLAMACPP_FALLBACK_MODEL=qwen3:30b-a3b \
+LOCAL_LLAMACPP_FALLBACK_VERIFY_MODEL=qwen3:30b-a3b \
+LOCAL_LLAMACPP_FALLBACK_LOAD_FLAGS='--host 127.0.0.1 --port 8081 --alias qwen3:30b-a3b --reasoning off ...' \
+make scenario-local-llamacpp-fallback
+```
+
+Without `RUN_LOCAL_LLAMACPP_FALLBACK_SCENARIO=1`, the command records a plan/report only. It does not start Ollama, does not start `llama-server`, and does not run heavy local inference.
+
+## Why this cannot close yet
+
+The dry-run validation checked the configured loopback endpoint:
+
+- Base URL: `http://127.0.0.1:8081/v1`
+- Model: `qwen3:30b-a3b`
+- Verify model: `qwen3:30b-a3b`
+- Output report: `tmp/local_llamacpp_fallback/report.md`
+- JSON report: `tmp/local_llamacpp_fallback/report.json`
+
+The endpoint was not available:
+
+```text
+list llama.cpp models: Get "http://127.0.0.1:8081/v1/models": dial tcp 127.0.0.1:8081: connect: connection refused
+```
+
+Because `/v1/models` returned `connection refused`, the runner correctly stayed in `plan_only` mode and did not attempt draft generation. This means the implementation path exists, but there is still no hardware/model evidence that local llama.cpp fallback can meet the draft quality gate.
+
+## Pass/fail thresholds for closure
+
+To close #36, a future live run must record all of the following in `tmp/local_llamacpp_fallback/report.json`:
+
+| Field | Required value |
+|---|---:|
+| `status` | `passed` |
+| `explicit_run` | `true` |
+| `runtime.local_fallback_only` | `true` |
+| `runtime.fallback_chain_disabled` | `true` |
+| `endpoint.available` | `true` |
+| `thresholds.min_style_score` | `82.0` |
+| `thresholds.min_keyword_overlap` | `70` |
+| `thresholds.min_draft_runes` | `2800` |
+| `result.scenario_passed` | `true` |
+| `result.score` | `>= 82.0` |
+| `result.keyword_overlap` | `>= 70` |
+| `result.runes` | `>= 2800` |
+| `result.verification_passed` | `true` when verification is performed |
+
+The report must also preserve the exact base URL, model alias, verify model, elapsed seconds, score, keyword overlap, runes, and `LOCAL_LLAMACPP_FALLBACK_LOAD_FLAGS` used for the real hardware/model run.
+
+## Evo X2 primary safety
+
+This validation path is separate from Evo X2 primary validation:
+
+- The default primary remains Evo X2 Ollama through `make scenario-evo-x2`.
+- The local fallback runner accepts only loopback hosts such as `127.0.0.1`, `localhost`, or `::1`.
+- Evo X2 hostnames are rejected by the local fallback runner.
+- The runner clears the normal fallback chain before draft generation, so a local fallback result cannot be confused with Evo X2 primary or Evo X2 llama.cpp fallback.
+- Plan mode is the default unless the explicit live env var is present.
+
+Therefore, the #36 tooling does not block or alter the Evo X2 primary path.
+
+## Validation performed
+
+Commands run after the implementation:
+
+```sh
+go test ./cmd/scenario/local_llamacpp_fallback
+make scenario-local-llamacpp-fallback
+```
+
+Expected current outcome:
+
+- The Go test passes.
+- The Make target succeeds in `plan_only` mode.
+- The Make target records `connection refused` if no local llama.cpp endpoint is listening on `127.0.0.1:8081`.
+
+## Closure decision

+# Issue #36 local llama.cpp fallback validation template
+
+Date: YYYY-MM-DD
+
+## Purpose
+
+Validate only the workstation-local llama.cpp fallback path. This is not Evo X2 primary validation and must not use the normal fallback chain.
+
+## Required live gate
+
+Live draft generation requires:
+
+```sh
+RUN_LOCAL_LLAMACPP_FALLBACK_SCENARIO=1
+```
+
+Without that variable, the runner writes a plan/report and exits without starting or using a local model. The runner never starts Ollama or `llama-server`.
+
+## Endpoint and load flags
+
+Record the exact already-running llama.cpp endpoint:
+
+- Base URL: `http://127.0.0.1:8081/v1`
+- Model alias: `qwen3:30b-a3b`
+- Load flags: `PASTE llama-server flags here`
+
+Example command to record a plan or unavailable-endpoint report:
+
+```sh
+make scenario-local-llamacpp-fallback
+```
+
+Example live command after the local llama.cpp endpoint is already available:
+
+```sh
+RUN_LOCAL_LLAMACPP_FALLBACK_SCENARIO=1 \
+LOCAL_LLAMACPP_FALLBACK_BASE_URL=http://127.0.0.1:8081/v1 \
+LOCAL_LLAMACPP_FALLBACK_MODEL=qwen3:30b-a3b \
+LOCAL_LLAMACPP_FALLBACK_VERIFY_MODEL=qwen3:30b-a3b \
+LOCAL_LLAMACPP_FALLBACK_LOAD_FLAGS='--host 127.0.0.1 --port 8081 --alias qwen3:30b-a3b --reasoning off ...' \
+make scenario-local-llamacpp-fallback
+```
+
+## Required artifacts
+
+The dedicated runner writes:
+
+- Report: `tmp/local_llamacpp_fallback/report.md`
+- JSON: `tmp/local_llamacpp_fallback/report.json`
+- Draft: `tmp/local_llamacpp_fallback/draft_generation/draft.md`
+- Evaluation: `tmp/local_llamacpp_fallback/draft_generation/evaluation.json`
+- Verification: `tmp/local_llamacpp_fallback/draft_generation/verification.json`
+- Command logs: `tmp/local_llamacpp_fallback/logs/*.stdout` and `*.stderr`
+
+## Acceptance threshold
+
+Record the final values from `report.json`:
+
+| Field | Required |
+|---|---:|
+| `runtime.local_fallback_only` | `true` |
+| `runtime.fallback_chain_disabled` | `true` |
+| `endpoint.available` | `true` |
+| `thresholds.min_style_score` | `82.0` |
+| `thresholds.min_keyword_overlap` | `70` |
+| `thresholds.min_draft_runes` | `2800` |
+| `result.scenario_passed` | `true` |
+| `result.score` | `>= 82.0` |
+| `result.keyword_overlap` | `>= 70` |

+# Issue #45 llama.cpp swap orchestration validation - 2026-05-03
+
+Issue: [#45](https://github.com/terisuke/note_maker/issues/45)
+
+## Scope
+
+This validation covers runtime operations design and local safety checks for
+Evo X2 llama.cpp fallback orchestration. It does not restart or kill Evo X2
+services.
+
+## Implemented controls
+
+- `scripts/evo-x2-llama-swap.sh inspect` reads the Ollama primary models,
+  llama.cpp fallback models, and remote systemd status when SSH is available.
+- `scripts/evo-x2-llama-swap.sh plan` prints the systemd profile strategy and
+  start/swap commands without changing Evo X2.
+- `scripts/evo-x2-llama-swap.sh start` is dry-run by default and requires
+  `EVO_X2_LLAMA_CPP_APPLY=1` for remote execution.
+- `scripts/evo-x2-llama-swap.sh swap` is dry-run by default and requires both
+  `EVO_X2_LLAMA_CPP_APPLY=1` and `EVO_X2_LLAMA_CPP_ALLOW_RESTART=1` before it
+  restarts the shared llama.cpp fallback service.
+- The script refuses to operate if the Ollama primary URL and llama.cpp fallback
+  URL are accidentally identical.
+
+## Make targets
+
+```bash
+make evo-x2-llama-status
+make evo-x2-llama-plan
+make evo-x2-llama-start
+make evo-x2-llama-swap
+make evo-x2-llama-check
+RUN_EVO_X2_LLAMA_CPP_SCENARIO=1 make scenario-evo-x2-llama-brief-draft
+```
+
+The live brief/draft scenario is explicitly gated by
+`RUN_EVO_X2_LLAMA_CPP_SCENARIO=1`. It targets
+`EVO_X2_LLAMA_CPP_LLM_BASE_URL` directly and clears fallback URLs, so it cannot
+silently pass through Ollama.
+
+## Local validation commands
+
+```bash
+make evo-x2-llama-check
+make -n evo-x2-llama-status
+make -n evo-x2-llama-plan
+make -n evo-x2-llama-start
+make -n evo-x2-llama-swap
+make -n scenario-evo-x2-llama-brief-draft
+```
+
+Results:
+
+- `make evo-x2-llama-check`: passed; `bash -n` accepted `scripts/dev.sh`,
+  `scripts/evo-x2-tailnet-preflight.sh`, `scripts/evo-x2-ssh-preflight.sh`,
+  and `scripts/evo-x2-llama-swap.sh`.
+- `make -n evo-x2-llama-status`: passed; printed the inspect command only.
+- `make -n evo-x2-llama-plan`: passed; printed the plan command only.
+- `make -n evo-x2-llama-start`: passed; printed the dry-run start command only.
+- `make -n evo-x2-llama-swap`: passed; printed the dry-run swap command only.
+- `make -n scenario-evo-x2-llama-brief-draft`: passed; printed the env-gated
+  scenario command without running it.
+- `./scripts/evo-x2-llama-swap.sh plan`: passed; printed start/swap commands
+  and post-check curls without SSH or service changes.
+- `./scripts/evo-x2-llama-swap.sh start`: passed; dry-run only.
+- `./scripts/evo-x2-llama-swap.sh swap`: passed; dry-run only.
+- `EVO_X2_LLAMA_CPP_APPLY=1 ./scripts/evo-x2-llama-swap.sh swap`: refused
+  before SSH because `EVO_X2_LLAMA_CPP_ALLOW_RESTART=1` was not set.
+- `make scenario-evo-x2-llama-brief-draft`: refused before preflight because
+  `RUN_EVO_X2_LLAMA_CPP_SCENARIO=1` was not set.
+- URL guard check with identical Ollama and llama.cpp URLs: refused with exit 2.
+- `make evo-x2-llama-status`: read-only check passed. Ollama primary reported
+  installed models including `gemma4:31b`, `gemma4:e2b`, `gemma4:latest`,
+  `qwen3.6:27b`, `qwen3:30b-a3b`, and `gpt-oss:120b`. The llama.cpp fallback
+  at `/llama/v1/models` reported one active model:
+  `gemma-4-E2B-it-Q8_0.gguf`. The default configured systemd service name
+  `note-maker-llama-cpp.service` reported `inactive`, so Evo X2's actual
+  service name should be supplied through `EVO_X2_LLAMA_CPP_SERVICE` before any
+  apply-mode start/swap command.
+- `go test ./...`: passed.
+
+## Live validation command
+
+Use the same brief/draft scenario metrics used around #18 streaming and the
+current Evo X2 full workflow checks:
+
+```bash
+RUN_EVO_X2_LLAMA_CPP_SCENARIO=1 \
+EVO_X2_LLAMA_CPP_MODEL=gemma-4-E2B-it-Q8_0.gguf \
+EVO_X2_LLAMA_CPP_STYLE_MODEL=gemma-4-E2B-it-Q8_0.gguf \
+EVO_X2_LLAMA_CPP_BRIEF_MODEL=gemma-4-E2B-it-Q8_0.gguf \
+EVO_X2_LLAMA_CPP_DRAFT_MODEL=gemma-4-E2B-it-Q8_0.gguf \
+EVO_X2_LLAMA_CPP_VERIFY_MODEL=gemma-4-E2B-it-Q8_0.gguf \
+make scenario-evo-x2-llama-brief-draft
+```
+
+Required reported metrics:
+
+- `scenario_passed`
+- `score`
+- `min_style_score`
+- `runes`
+- `min_draft_runes`
+- `verification_performed`
+- `verification_passed`
+- `elapsed_seconds`
+- `streaming`
+- `first_chunk_ms`
+- `chunks`
+- `llm_base_url`
+- `llm_model`
+- `verify_model`
+
+## Live Validation Pending Criteria
+
+Use this checklist as the concrete issue comment/update before closing #45.
+
+Preflight and service identity:
+
+- Record the real Evo X2 llama.cpp systemd unit name and pass it as
+  `EVO_X2_LLAMA_CPP_SERVICE`; the placeholder
+  `note-maker-llama-cpp.service` reported `inactive` during the read-only check.
+- Record the active profile name, active env path, model path or HF file,
+  exposed alias, context size, and GPU/Vulkan/RADV flags.
+- Run `make evo-x2-llama-status` before the scenario and paste the Ollama
+  primary `/v1/models` result plus the llama.cpp `/llama/v1/models` active
+  model. The llama.cpp result must show exactly the alias being validated.
+- If a profile swap is required, perform it only with both
+  `EVO_X2_LLAMA_CPP_APPLY=1` and `EVO_X2_LLAMA_CPP_ALLOW_RESTART=1`, and record
+  the maintenance window or operator confirmation. No command may kill or
+  restart Ollama.
+
+Direct llama.cpp scenario:
+
+- Run `RUN_EVO_X2_LLAMA_CPP_SCENARIO=1 make scenario-evo-x2-llama-brief-draft`
+  or the equivalent expanded command from this document.
+- Confirm the scenario output includes
+  `llm_base_url=http://evo-x2.tailb30e58.ts.net/llama/v1` or the configured
+  `EVO_X2_LLAMA_CPP_LLM_BASE_URL`.
+- Confirm `LLM_FALLBACK_BASE_URLS` is empty for the run so success cannot come
+  from Ollama or workstation-local fallback.
+- Attach or link the generated `tmp/author_style`, `tmp/brief_interview`, and
+  `tmp/draft_generation` artifacts, especially `draft.md`, `evaluation.json`,
+  and `verification.json`.
+
+Pass gates:
+
+- Brief phase completes against `/llama/v1`.
+- Draft phase streams with `streaming=true`, `chunks > 0`, and a recorded
+  `first_chunk_ms`.
+- Warm first chunk meets the #18-style target of `first_chunk_ms <= 3000`; if
+  it does not, keep #45 open and record the observed latency as an operations
+  miss.
+- `scenario_passed=true`.
+- `score >= 80.0`.
+- `runes >= 2800`.
+- `verification_performed=true` and `verification_passed=true`, or an explicit
+  reason is recorded if final verification is intentionally unavailable for the
+  active llama.cpp profile.
+- `elapsed_seconds`, `llm_model`, and `verify_model` are recorded.
+
+Ollama safety gates:
+
+- Run `make evo-x2-models` or equivalent Ollama `/v1/models` check after the
+  llama.cpp scenario; it must still pass.
+- The run must not change the app default primary from Ollama to llama.cpp.
+- No other Evo X2 users should lose the shared Ollama Tailnet primary during
+  the test. If there is any service interruption or resource starvation,
+  record it and keep #45 open.
+
+Close #45 only when every pass and safety gate above is satisfied. Otherwise,
+comment on #45 with the failed gate, observed metrics, active profile, and next
+specific follow-up.
+
+## Live validation result - 2026-05-03
+
+Command:
+
+```bash
+RUN_EVO_X2_LLAMA_CPP_SCENARIO=1 make scenario-evo-x2-llama-brief-draft
+```
+
+Path controls:
+
+- `llm_base_url=http://evo-x2.tailb30e58.ts.net/llama/v1`
+- `LLM_FALLBACK_BASE_URLS=""`
+- `STYLE/BRIEF/ARTICLE/DRAFT/VERIFY_LLM_FALLBACK_MODELS=""`
+- No swap, restart, or apply-mode command was run.
+- Post-run `make evo-x2-models` passed, so the Ollama primary endpoint remained
+  available after the direct llama.cpp scenario.
+
+Observed output:
+
+| Metric | Value |
+|---|---:|
+| brief elapsed seconds | `42.59` |
+| draft elapsed seconds | `59.33` |
+| scenario_passed | `true` |
+| score | `88.2 / 80.0` |
+| keyword_overlap | `65 / 70` |
+| runes | `3075 / 2800` |
+| verification_performed | `true` |
+| verification_passed | `true` |
+| streaming | `true` |
+| first_chunk_ms | `14105` |
+| chunks | `1785` |
+| llm_model | `gemma-4-E2B-it-Q8_0.gguf` |
+| verify_model | `gemma-4-E2B-it-Q8_0.gguf` |
+
+Artifacts:
+
+- `tmp/author_style/profile.json`
+- `tmp/author_style/guide.md`
+- `tmp/brief_interview/brief.json`
+- `tmp/draft_generation/draft.md`
+- `tmp/draft_generation/evaluation.json`
+- `tmp/draft_generation/verification.json`
+
+Outcome:
+
+- The direct `/llama/v1` scenario can complete without falling back to Ollama.
+- Draft throughput and final verification were good enough for a fallback proof.
+- It is not ready to promote over Ollama: strict style evaluation failed on
+  `keyword_overlap=65 below 70`, and first chunk latency was `14105ms`, above
+  the #18-style streaming target.
+
+## Closure status
+
+#45 remains pending until the live Evo X2 llama.cpp brief/draft validation runs
+against the selected active profile and proves quality plus operations gates.
+The 2026-05-03 live run proves the route works, but it missed keyword-overlap
+and first-chunk gates. The current implementation is intentionally P2: Ollama
+remains primary.

 Original recommended order was A → C → B → D. Implementation intentionally pulled the minimum B work forward because source acquisition, format validation, persona seeds, and question templates were required before a realistic cross-media evaluation could be defined. With Phases A and B now implemented, the 2026-05-03 implementation cut lands C1, D1, and the #57 runner foundation in parallel. The next order is C2/C3, one bounded Evo X2 runner validation, then the full Evo X2 media-matrix evaluation under #40.
@@ -254,13 +254,15 @@ Current implementation status as of 2026-05-03:
 - The #74 pass required additional hardening that is now part of the architecture: frontmatter preamble/fence normalization, recoverable frontmatter repair, bounded repair/revision/final-verification calls, case-specific style profiles, final verifier format-guide grounding, best-attempt selection across retries, and explicit quality-gate aggregate output.
 - The #70-#73 prerequisite slice is now in place for #74: interview-template coverage exists, failed draft artifacts are preserved, format-only failures can be repaired once without relaxing validators, and scenario gates are split by output format. The first staged #74 Tailnet rerun used `cloudia_zenn_tutorial` and moved past the original failure class but failed strict style (`73.6 / 82.0`). The current cut fixes the reliability gap behind that score by generating case-specific style profile/guide artifacts, passing them into live runs, rejecting profile/guide/brief mismatches, making final verification block `scenario_passed`, enforcing structural signals, and exposing UI `quality_gate` details. The bounded reruns now pass both Cloudia technical proofs: `cloudia_zenn_tutorial` scored `88.1 / 82.0` with `5040 / 1800` runes, and `cloudia_qiita_how_to` scored `83.7 / 82.0` with `3318 / 1400` runes. Both used the Tailnet endpoint `http://evo-x2.tailb30e58.ts.net/v1` and passed lightweight verification. Validation is recorded in [Issue 74 staged Evo X2 rerun](../validation/issue-74-staged-evo-x2-rerun-2026-05-03.md).
 - The #45 llama.cpp swap orchestration cut now has a documented conservative fallback strategy, dry-run default Make targets, and a gated direct `/llama/v1` brief/draft scenario target. It does not change the primary runtime decision: Ollama remains primary until the live #45 criteria prove active-profile quality and operations safety.
+- PR #87 closes the current app-baseline scope for [#14](https://github.com/terisuke/note_maker/issues/14) and [#15](https://github.com/terisuke/note_maker/issues/15): custom personas can be created, updated, and deleted with history-reference protection; saved briefs have explicit versions; the UI exposes brief-version history; and `make launcher` / `make app` provide managed startup with Evo X2 health checks, port selection, storage defaults, and explicit-only local LLM startup. Operational handoff is recorded in [Note Maker app handoff](../handoffs/app-handoff-2026-05-03.md).
+- The remaining open runtime issues are intentionally narrow: [#36](https://github.com/terisuke/note_maker/issues/36) for workstation-local llama.cpp fallback quality and [#45](https://github.com/terisuke/note_maker/issues/45) for Evo X2 llama.cpp latency/quality before any promotion beyond fallback.
 
 Near-term execution order:
 
-1. Close [#74](https://github.com/terisuke/note_maker/issues/74) and [#40](https://github.com/terisuke/note_maker/issues/40) for the current note/Qiita/Zenn/Cor blog publishing-target scope after linking the final `5/5` aggregate artifacts. Homepage remains a separate short-format check.
-2. Treat [#13](https://github.com/terisuke/note_maker/issues/13) as covered by the browser E2E validation cut; do not move Phase C product gaps back into browser-coverage scope.
-3. Keep [#14](https://github.com/terisuke/note_maker/issues/14) open for broader queryable product memory and split custom persona update/delete or brief-version history if those become required beyond this cut.
-4. Keep fallback-quality and runtime packaging follow-up ([#36](https://github.com/terisuke/note_maker/issues/36), [#45](https://github.com/terisuke/note_maker/issues/45), [#15](https://github.com/terisuke/note_maker/issues/15)) outside the #40 closure gate. For #45, design/script acceptance can land before closure, but live direct-llama.cpp brief/draft validation remains required.
+1. Promote the app baseline from `develop` to `main` after the docs handoff PR passes.
+2. Keep [#36](https://github.com/terisuke/note_maker/issues/36) open until a workstation-local loopback llama.cpp endpoint records `score >= 82`, `keyword_overlap >= 70`, and `runes >= 2800`.
+3. Keep [#45](https://github.com/terisuke/note_maker/issues/45) open until direct Evo X2 `/llama/v1` validation meets latency and keyword-overlap gates without disrupting Ollama primary.
+4. Split optional signed-native packaging, brief-version diff/restore, or richer persona-source management into new narrow issues only when needed by actual use.

+# Note Maker app handoff - 2026-05-03
+
+This handoff records the current app-like release baseline after PR #87 and is
+the starting point for develop-to-main promotion.
+
+## Current branch and release state
+
+- Source branch: `develop`
+- Latest merged app cut: PR #87, merge commit `4af05cadaeacc5fa10bdd22aa4d5992200c7d8ba`
+- Closed by PR #87: [#14](https://github.com/terisuke/note_maker/issues/14), [#15](https://github.com/terisuke/note_maker/issues/15)
+- Still open by design: [#36](https://github.com/terisuke/note_maker/issues/36), [#45](https://github.com/terisuke/note_maker/issues/45)
+
+The app is usable as a local web app through the launcher. It is not a signed
+native desktop bundle yet.
+
+## How to start the app
+
+Recommended path:
+
+```bash
+make launcher
+```
+
+Equivalent alias:
+
+```bash
+make app
+```
+
+The launcher:
+
+- builds and starts the Go server,
+- chooses the requested port or the next available port,
+- opens the browser unless `--no-open` is used,
+- stores app data in a user data directory,
+- checks Evo X2 Tailnet primary LLM health before startup,
+- reports fallback health,
+- stops the managed server on `Ctrl-C` / `SIGTERM`,
+- does not start the workstation-local LLM unless explicitly requested.
+
+Useful variants:
+
+```bash
+make launcher-status
+make launcher-check
+make launcher-local
+./scripts/launcher.sh --allow-degraded
+./scripts/launcher.sh --strict-port
+```
+
+Use `make launcher-local` only for an intentional local-LLM diagnostic. The
+product default is Evo X2 Ollama over Tailnet.
+
+## Runtime contract
+
+Primary runtime:
+
+```text
+http://evo-x2.tailb30e58.ts.net/v1
+```
+
+Fallback order:
+
+1. Evo X2 Ollama OpenAI-compatible API over Tailnet.
+2. Evo X2 llama.cpp OpenAI-compatible API at `/llama/v1`.
+3. Workstation-local llama.cpp at `http://127.0.0.1:8081/v1`.
+
+SSH tunnels are diagnostics only. They must not become the app default because
+they depend on per-device authentication and cannot be shared by other Tailnet
+devices.
+
+Phase model defaults:
+
+| Phase | Default |
+|---|---|
+| Style/source summarization | `gemma4:e2b` |
+| Brief follow-up questions | `qwen3.6:27b` |
+| Article compatibility generation | `gemma4:e2b` |
+| Draft generation | `gemma4:31b` |
+| Final verification | `gemma4:latest` |
+
+Users can override these from the app settings.
+
+## Storage contract
+
+The settings UI can switch between JSON and SQLite unless environment variables
+lock the store.
+
+- JSON compatibility store: `data/workflow_store.json`
+- SQLite store: `data/workflow_store.db`
+- Launcher user data directory:
+  - macOS: `~/Library/Application Support/Note Maker`
+  - Linux/other: `$XDG_DATA_HOME/note-maker` or `~/.local/share/note-maker`
+
+Current persisted product memory includes:
+
+- author style analyses and writing guides,
+- brief sessions and answers,
+- saved briefs and explicit brief versions,
+- projects, articles, source snapshots, drafts, draft versions, and final verification metadata in SQLite,
+- built-in plus custom personas,
+- custom persona update/delete with history-reference protection.
+
+## User-facing app surface
+
+Implemented:
+
+- persona and output-format selection for note, Cor blog, Zenn, Qiita, and homepage section output,
+- media-aware style-source presets,
+- plain fixed questions plus targeted deep dives,
+- SSE streaming and cancellation for follow-up and draft generation,
+- editable answer transcript with fork-on-edit lineage,
+- editable draft Markdown and section regeneration,
+- style/brief/project/article/draft/source history cards,
+- custom persona create/update/delete,
+- brief version history display,
+- storage-mode setting,
+- model setting.
+
+Known limitations:
+
+- The launcher is app-like, not a signed native bundle.
+- The local workstation llama.cpp fallback has tooling but no passing live proof yet.
+- Evo X2 llama.cpp `/llama/v1` works as a route, but is not ready to replace Ollama primary.
+- Brief version UI is read-only; diff/restore can be separate follow-up work.
+- Custom persona source management is minimal beyond the current source fields.
+
+## Validation baseline
+
+PR #87 validation:
+
+```bash
+go test ./...
+python3 -m pytest tests/e2e -q
+bash -n scripts/*.sh && zsh -n scripts/*.sh && ./scripts/check-launcher.sh
+git diff --check
+make scenario-local-llamacpp-fallback
+RUN_EVO_X2_LLAMA_CPP_SCENARIO=1 make scenario-evo-x2-llama-brief-draft
+make evo-x2-models
+```
+
+Observed #45 direct `/llama/v1` run:
+
+| Metric | Value |
+|---|---:|
+| `scenario_passed` | `true` |
+| score | `88.2 / 80.0` |
+| keyword overlap | `65 / 70` |
+| runes | `3075 / 2800` |
+| verification | passed |
+| first chunk | `14105ms` |
+| chunks | `1785` |
+| draft elapsed | `59.33s` |
+
+This proves the route is usable for fallback experimentation. It does not close
+#45 because first-chunk latency and keyword overlap still miss the promotion
+gates.
+
+Observed #36 local fallback status:
+
+- `make scenario-local-llamacpp-fallback` writes a plan/report without starting
+  a local model.
+- `http://127.0.0.1:8081/v1/models` returned `connection refused`.
+- #36 remains open until a gated local loopback llama.cpp run records
+  `score >= 82.0`, `keyword_overlap >= 70`, and `runes >= 2800`.
+
+## Main promotion checklist
+
+Before promoting develop to main:
+
+1. Confirm open issues are only expected follow-ups (#36 and #45 at the time of this handoff).
+2. Confirm no app-breaking PRs are open against develop.
+3. Run the fast validation baseline:
+
+```bash
+go test ./...
+python3 -m pytest tests/e2e -q
+./scripts/check-launcher.sh
+git diff --check
+```
+
+4. Create a develop-to-main PR.
+5. Verify GitHub checks.
+6. Merge the main PR.
+
+## Next engineering work
+
+Priority order:
+
+1. #36: start an approved workstation-local llama.cpp endpoint and capture a
+   live passing fallback report.
+2. #45: reduce Evo X2 llama.cpp first-token latency and improve
+   keyword-overlap consistency without disrupting Ollama primary.
+3. Split optional app packaging follow-ups only if a signed native wrapper,
+   icon, signing, or installer is required.
+4. Add brief-version diff/restore only after users confirm the read-only
+   version history is useful.

-- Phase C (SQLite store): repository interfaces stay; only implementations change. JSON-file store remains the compatibility path, but storage selection must be visible in the web settings UI rather than hidden behind make/env setup. Phase C product completion requires persisted custom personas and editable human-readable artifacts, not only built-in persona selection and read-only cards; the current polish cut covers create/list and brief/style edits, while update/delete and broader artifact versioning remain follow-up scope.

-Implemented in the current #27/#28 history/artifact cut:
-
-- [#27](https://github.com/terisuke/note_maker/issues/27) — first saved-history UI cut: `履歴から再開`, persona-scoped saved style-guide and brief-session selectors, and open/clear/refresh controls.
-- [#28](https://github.com/terisuke/note_maker/issues/28) — first readable artifact cut: style-guide cards and article-brief cards replace raw-only `pre` output while keeping Markdown/JSON details available.
-- History read API surface — `GET /api/history`, `GET /api/workflow/artifacts`, `GET /api/author-style`, `GET /api/brief-sessions`, `GET /api/briefs`, and `GET /api/briefs/{id}`.
-- Store list support — memory and SQLite now expose `ListAuthorStyles`, `ListSessions`, and `ListBriefs`; SQLite also has `ListProjects` and `ListArticlesByProject` for the richer #26 schema.
-- Focused tests — `internal/handlers/workflow_history_test.go` covers saved artifact responses and brief detail errors; `static/history_ui_test.go` locks the frontend contract.
-- Validation — [Issue 27/28 history and artifact UI/API validation](../validation/issue-27-28-history-artifacts-2026-05-03.md).
-
-Implemented in the #13 follow-up contract cut:
-
-- Static browser contract coverage checks the HTML entrypoint, production script, model selectors, question controls, history controls, artifact-card containers, persistence hooks, and route-table wiring.
-- This is useful pre-Playwright coverage, but it is not equivalent to browser E2E. It does not exercise real DOM events, fetch stubbing, localStorage reload behavior, SSE/cancel, or the section-regeneration workflow in a browser.
-- Validation — [Issue #13 Browser Contract Coverage](../validation/issue-13-browser-contract-coverage-2026-05-03.md).
-
-Implemented in the `codex/issue13-browser-e2e` cut:
-
-- Python `pytest` plus Playwright starts the real Go server on a free localhost port and stubs application APIs through browser route handlers.
-- Browser tests now cover model selector persistence, legacy localStorage migration, persona/format switching, custom question CRUD/reset, interview start payloads, answer SSE submission/cancel recovery, saved history opening/readable cards, edit/fork, draft streaming/cancel recovery, and section regeneration reject/accept.
-- Validation — [Issue #13 Browser E2E Validation](../validation/issue-13-browser-e2e-2026-05-03.md).

-
-Resolved validation baseline:
-
-- Browser E2E coverage: [#13](https://github.com/terisuke/note_maker/issues/13) is closed by the Playwright validation cut. Track remaining Phase C product work under #14/#27/#28.
-
-Implemented in this Phase C polish cut:
-
-- `GET /api/personas` returns built-in and user-authored personas; `POST /api/personas` validates and persists custom personas.
-- Memory and SQLite stores persist custom personas; SQLite restore after reopen is covered.
-- The web UI exposes an add-persona form, selects the new persona after save, keeps the history persona selector aligned, and reloads the saved persona through the API.
-- Style-guide cards can be edited and saved through `PATCH /api/author-style/{id}` / `POST /api/author-style/{id}/versions`; the server stores the edit as a new style-guide version.
-- Brief cards can be edited and saved through `PATCH /api/briefs/{id}`; the saved artifact updates while existing session answers remain auditable.
-- Phase C E2E covers custom persona add/reload plus brief/style card save, cancel, and error behavior.
-
-Remaining Phase C limitations:
-
-- Custom persona update/delete is not implemented.
-- Persona source management is minimal: create accepts initial source metadata, while richer source editing remains future work.
-- Brief-card edits update the saved brief artifact; they do not rewrite the original interview answers or create a separate brief-version table.
-- #14 remains open for full queryable product memory and broader version/history semantics beyond this cut.

+## Current validation baseline
 
-Validation that passed:
+Fast local checks:
 
-```sh
+```bash
 go test ./...
-go test ./internal/handlers ./static
-go test ./cmd/server ./internal/handlers ./static
-node --check static/js/script.js
+python3 -m pytest tests/e2e -q
+./scripts/check-launcher.sh
 git diff --check
 ```
 
-No blocking code-risk finding remains in the targeted suite after the parallel fixes. The #13 browser E2E closure risk is resolved by the `tests/e2e` suite. The Phase C polish validation now covers custom persona create/list and editable brief/style card persistence; #14 remains the broader product-memory umbrella.

-## Issue Close/Open Proposal
-
-| Issue | Proposal | Rationale |
-|---|---|---|
-| [#13](https://github.com/terisuke/note_maker/issues/13) | Closed | Browser E2E validation covers model config, questions, persona/format switching, history/cards, streaming/cancel, edit/fork, and regenerate-section. |
-| [#14](https://github.com/terisuke/note_maker/issues/14) | Keep open | #26 gives the SQLite schema, the current branch exposes project/article/draft read cards, and this cut adds custom persona persistence plus editable brief/style cards. Broader queryable product memory, persona update/delete, and complete artifact version/history semantics remain. |
-| [#27](https://github.com/terisuke/note_maker/issues/27) | Close with this PR if the issue owner accepts create/list as the custom-persona scope | Saved style-guide/session/project/article/draft selectors are implemented, custom personas can be created/listed/persisted, and E2E covers selecting the saved persona and loading its history after reload. Custom persona update/delete should be tracked separately if needed. |
-| [#28](https://github.com/terisuke/note_maker/issues/28) | Close with this PR if the issue owner accepts brief/style edit persistence as the card scope | Readable style-guide and brief cards are editable with save/cancel/error behavior. Style edits create a new saved guide version; brief edits persist the saved artifact while leaving original session answers auditable. |
-
-## Final evaluation target
-
-The final integrated evaluation should use `cmd/scenario/media_matrix` as the input matrix, then run live Evo X2 Tailnet draft scenarios for:
-
-| Case | Medium | Style | Primary source |
-|---|---|---|---|
-| `terisuke_note_essay` | note | reflective essay | `note:cor_instrument` |
-| `cor_blog_technical_report` | Cor.inc blog | technical report | `github:Cor-Incorporated/corsweb2024/src/content/blog/ja` |
-| `cor_blog_vision_sharing` | Cor.inc blog | vision sharing | `github:Cor-Incorporated/corsweb2024/src/content/blog/ja` |
-| `cloudia_zenn_tutorial` | Zenn | tutorial | `zenn:cloudia` |
-| `cloudia_qiita_how_to` | Qiita | practical how-to | `qiita:Cloudia_Cor_Inc` |
-
-The homepage section case remains in the matrix as a useful format check, but the user-facing publishing targets for the full Evo X2 run are note, Qiita, Zenn, and the company blog.
-
-Each live run must record:
-
-- endpoint and whether it was primary or fallback,
-- model per phase,
-- elapsed seconds,
-- generated runes,
-- style score and failed metrics,
-- final verification result,
-- output path and scenario case id.
+Runtime checks:
 
-## Current #74 status
-
-The #70-#73 prerequisites are in place. The first staged #74 Tailnet rerun intentionally targeted one previously failing medium, `cloudia_zenn_tutorial`, and isolated the remaining failure:
-
-| Layer | Result |
-|---|---|
-| Tailnet runtime | passed: Evo X2 OpenAI-compatible endpoint responded and streamed metrics |
-| Format validation | passed: generated Markdown was accepted as Zenn output |
-| Length gate | passed: `3905` runes against `1800` minimum |
-| Final verification | passed with `gemma4:latest` |
-| Strict style gate | failed: `73.6 / 82.0` |
-
-The current cut fixed the evaluation reliability gap before trusting that score:
-
-- `cmd/scenario/media_matrix` now emits case-specific style `profile.json` and `guide.json`.
-- `cmd/scenario/live_media_matrix` passes those artifacts into `cmd/scenario/draft_generation`.
-- Draft generation rejects profile/guide/brief style-profile mismatches.
-- Final verification failure now blocks `scenario_passed`.
-- Structural signals are enforced, not only reported.
-- The web response includes `quality_gate` details so failed scores keep the draft visible.
+```bash
+make launcher-status
+make scenario-local-llamacpp-fallback
+RUN_EVO_X2_LLAMA_CPP_SCENARIO=1 make scenario-evo-x2-llama-brief-draft
+make evo-x2-models
+```
 
-The bounded Cloudia technical proofs then passed:
+The #45 direct `/llama/v1` run on 2026-05-03 completed through the fallback
+route with `scenario_passed=true`, score `88.2`, `3075` runes, and final
+verification passed. It still missed promotion gates: `keyword_overlap=65/70`
+and `first_chunk_ms=14105`.
 
-| Case | Seconds | First chunk | Chunks | Score / min | Runes / min | Verification |
-|---|---:|---:|---:|---:|---:|---|
-| `cloudia_zenn_tutorial` | `741.93` | `86456ms` | `2205` | `88.1 / 82.0` | `5040 / 1800` | passed |
-| `cloudia_qiita_how_to` | `598.62` | `111645ms` | `1336` | `83.7 / 82.0` | `3318 / 1400` | passed |
+The #36 local fallback command currently records plan-only output because no
+loopback llama.cpp endpoint is listening on `127.0.0.1:8081`.
 
-The full publishing-target matrix now also passes:
+## Recommended next cut

-| `terisuke_note_essay` | 1 | `107.86` | `67818ms` | `1610` | `90.7 / 82.0` | `2849 / 2800` | passed |

+Do not reopen broad Phase A/B/C/D scope. The next implementation should be a
+small runtime hardening cut:
 
-Aggregate: `5/5` passed, `0` failed, average `122.01s`, average style score `86.0`, average `3742` runes. Artifacts are `tmp/media_matrix/live/aggregate.json` and `tmp/media_matrix/live/aggregate.md`.
+1. Pick either #36 or #45, not both, for the next PR.
+2. Keep Evo X2 Ollama as primary.
+3. Preserve explicit live gates for any LLM scenario.
+4. Record base URL, model, elapsed seconds, first chunk, chunks, score, keyword overlap, runes, and verification result.
+5. Update the corresponding validation doc before closing the issue.

-Use subagents with disjoint write scopes when implementation resumes:
+1. #36 if a safe workstation-local llama.cpp endpoint is available.
+2. #45 if Evo X2 llama.cpp service/profile details and latency tuning are available.
+3. Native packaging follow-up only after a user explicitly asks for a signed wrapper or installer.
 
-| Lane | Issue | Subagent role | Write scope | Done when |
-|---|---|---|---|---|
-| A | [#14](https://github.com/terisuke/note_maker/issues/14) | Persistence worker | future SQLite/history API and validation docs | custom personas, edited artifacts, projects, articles, drafts, source snapshots, and versions are queryable as one coherent product history |
-| B | Persona follow-up | Product worker | future persona edit/delete UI and API files | custom personas can be updated or removed without corrupting existing history references |
-| C | Artifact follow-up | Product worker | future artifact version UI and API files | brief edits have explicit version/history semantics comparable to style-guide versions |
+## Main promotion readiness
 
-Keep these lanes disjoint when implementation resumes; persona management and artifact history are adjacent but separable.
+The app baseline is ready for a develop-to-main PR when:
 
-## Recommended order
+- `develop` contains PR #87 and this docs handoff update,
+- open issues are expected follow-ups only (#36 and #45),
+- fast local checks pass,
+- GitHub checks on the docs PR pass.
 
-1. Use the #13 Playwright validation as the browser baseline; do not track Phase C product gaps as browser-E2E debt.
-2. Merge this Phase C polish cut if the validation document stays green, then close #27/#28 according to the issue-owner scope decision.
-3. Keep #14 open for complete queryable product memory and decide whether custom persona update/delete or brief-version tables need separate follow-up issues.
-4. Keep #36/#45 as fallback/runtime P2 work and #15 as packaging after persistence/history are usable. Homepage remains a separate short-format check, not part of the #40 closure gate.
+Use the handoff checklist in
+[Note Maker app handoff](../handoffs/app-handoff-2026-05-03.md#main-promotion-checklist)
+for the main PR.

 - The frontend is still one static JavaScript file. That is acceptable for the current local-first prototype; the #13 browser E2E cut now provides a baseline before #27/#28 add more stateful UI.
 
-Conclusion: the domain model and application services match ADR 0002 well enough to continue. The largest architectural risk is not the domain vocabulary; it is handler-led orchestration and hidden runtime configuration. The next implementation sequence should reduce those two risks before the full Evo X2 media-matrix evaluation.
