 ## 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.
