Switch style analysis source by persona and format

@@ -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.
 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 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.
