chore: pause task-numbers [board-viewer-ux-task-numbers]

User defers cross-repo migration to a separate session per Rule 1+2 (touching 5 whitelisted repos' STATUS.md sits outside the autonomous scope of this branch). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

+## 🟢 [board-viewer-drawer-bundle-md] — fix `Failed to fetch` в drawer: bundle md-content в build-time
+**Status:** done
+**Where I stopped:** TaskRecord.md_content bundled в build-time через `client.getFile(.tasks/<slug>.md)`. Drawer читает `recordsBySlug.get(slug).md_content` вместо fetch — 0 runtime запросов к git.kzntsv.site/raw. Fallback на status-block dl когда md=null. 3 новых reader-теста + 1 render-тест.
+**Next action:** ops redeploy на VDS (см. .admin/[board-viewer-redeploy-ux-round1]).
+**Branch:** master
+<!-- closed-by: OpeItcLoc03 / 2026-05-22 / note: code-complete (52→56 tests pass, typecheck clean). Live smoke (board.kzntsv.site после redeploy + DevTools network 0 git.kzntsv.site/raw hits) — ops-side. -->

-**Status:** ready (critical bug)
-**Where I stopped:** (not started — diagnose grounded: приватные репо + `fetch(rawUrl, {credentials:'omit'})` без auth → Gitea 401/302→login → TypeError. Решение — bundle per-task .md в build-time в JSON/inline script, drawer читает локально.)
-**Next action:** см. `board-viewer-drawer-bundle-md.md`. TDD mode. Сначала reader test: `TaskRecord.md_content?: string`. Затем render embeds JSON-bundle. Затем `static/board.js openDrawer` читает local instead of fetch. E2E smoke в browser-driver: 0 запросов на git.kzntsv.site/raw при клике.

+**Next action:** ops redeploy.

+## 🟢 [board-viewer-ux-owner-conditional] — скрывать owner-pill когда все таски одного owner'а
+**Status:** done
+**Where I stopped:** `distinctOwner(records)` pre-scan: единственный owner → pill убирается со всех карточек, в header добавляется `<span class="owner-summary">Owner: X</span>`; 2+ owners → pill возвращается на карточки. Поведение симметрично в `render.ts` и `static/board.js` (через `SOLO_OWNER` constant). 4 новых render-теста (mono / multi / mono-summary / multi-omits-summary).

+## 🟡 [board-viewer-ux-task-numbers] — shorthand numbering (BV-12) на карточке
+
+**Status:** paused (cross-repo migration outside autonomous scope)
+**Where I stopped:** (paused 2026-05-22 — user choice: defer до отдельной сессии. 4 design-вопроса остаются: scope per-repo/global, source-of-truth `<!-- num: ... -->` vs auto-derive, format BV-12 vs T-001, ретроактивно или нет. Recommendations в `board-viewer-ux-task-numbers.md` — все 4 имеют preferred answer.)
+**Next action:** Возобновить в отдельной user-session. Decision-tree: либо «board-viewer-impl-only» (TDD parser+render+badge, ретроактивная нумерация — отдельная chore-таска), либо «full cross-repo» (impl + 5 whitelisted repos retro-numbering, отдельные commit'ы per-repo).

-
-**Status:** ready
-**Where I stopped:** (not started — 3 design questions: TZ МСК/UTC, format readable/ISO, оставить ли relative «7h». Recommendations внутри `board-viewer-ux-full-datetime.md`.)
-**Next action:** TDD mode. Resolve 3 design-вопроса (или принять recommendations: МСК с явным суффиксом, `YYYY-MM-DD HH:MM МСК`, relative сохранить тоненькой строкой). Затем failing test + impl в `src/render.ts`.

-
-**Status:** ready
-**Where I stopped:** (not started — текущий VDS whitelist single-owner `OpeItcLoc03/*` → pill дублируется visual noise. Рендерить условно: single-owner → шапка «Owner: X (N repos)», без pill; multi-owner → pill на карточках.)
-**Next action:** TDD mode. Два теста (single/multi owner fixtures). Impl в `src/render.ts`. Связанный ops-audit в `.admin/[board-viewer-redeploy-ux-round1]`: verify `auth.toml board_viewer_repos` (по memory `books` = `victor/books`, не `OpeItcLoc03/books`).

-**Next action:** Resolve 4 design-вопроса (single user-session). Если рекомендации принимаются — TDD impl: parser извлекает `num` из block-comment, render показывает badge. Ретроспективно — отдельный proход «chore: number existing tasks». Если возникает дилемма — `.workshop/.brainstorm/board-viewer-task-numbers.md`.

-## ⚪ [board-viewer-ux-done-cutoff] — фильтр / cutoff длинного done-tail
-
-**Status:** ready (design-first)
-**Where I stopped:** (not started — 4 design-вопроса: что считать «archive-нужно» (все 🟢 или N дней+), source неизменен (recommend) vs физический archive, default hide vs show-all, тип cutoff (last-N / date / combined). Recommendations в `board-viewer-ux-done-cutoff.md`.)
-**Next action:** Resolve design (single user-session или brainstorm). Recommendations: source-неизменен, render-side cutoff = «hide done by default + toggle + last-10 fallback при show». TDD impl: render с N done>cutoff показывает только N + «N more» expander. Если дилемма — `.workshop/.brainstorm/board-viewer-done-cutoff.md`.
+## 🟢 [board-viewer-ux-done-cutoff] — фильтр / cutoff длинного done-tail
+**Status:** done
+**Where I stopped:** source неизменен (✓). Render-side cutoff: done column sort'ится by `last_commit_iso desc`, первые 10 видимы, rest `data-overflow="true"` (CSS hides), внизу column'а button `<button class="done-expander">show N more</button>`. Click → toggle `col.show-overflow` + button text `collapse`. Non-done колонки не trozhуются. 4 новых render-теста (overflow attr / expander / no-expander / non-done).
+**Next action:** ops redeploy.
