+**os-backlog AFK slices shipped (2026-07-10):** PRD published as Forgejo issue #9 (state
+pointer: Planka card `1816234194716592051`); sliced into issues #10–#17 via `/to-issues`.
+The five AFK slices are implemented and committed: #10 plugin scaffold + `board-ensure`
+(uniform lists/labels incl. new `semi` autonomy label, Planka 2.1.1 quirks, `archived--`
+rename convention), #11 `tracker` key in `.cc-os/config` + os-status `tracker-configured`
+check, #12 pure routing resolver CLI, #13 `/os-backlog:capture` + `/os-backlog:list`
+skills + card CLI, #15 `card-triage` + `board-audit` named agents. All deterministic parts
+covered by stubbed-client tests (34 runs os-backlog, 49 os-status). Semi slices #14
+(routing/migration skill), #16 (injection note + /to-issues routing), #17 (ops board +
+rubric category + routing ADR) await human decision gates. Note: the planka-api gem is not
+installed on this machine — fail-soft paths verified live; a live capture run is a
+follow-up on a machine with the gem + Planka credentials.

 **Remaining optional items:** additional project onboarding (one at a time, per ADR-013); bulk
 vault migration. All required build steps complete as of 2026-06-15.

+- Purpose: the AI's process-management surface over Planka — deterministic tracker routing
+  (Planka = task state by default; git issues = implementation specs only), mid-session
+  capture, pull-only listing, board lifecycle, and the three-value autonomy convention
+  (`hitl`/`semi`/`afk-ready`).
+- Lib (Ruby, os-adr `lib/`+`bin/` pattern, installed planka-api gem only — no source
+  coupling): `board_spec.rb` (uniform lists/labels contract), `board_ensurer.rb`
+  (idempotent create/repair; Planka 2.1.1 `type` fields, shared-project + owner-manager
+  visibility fix, label color candidates with fallback; `archived--` rename convention),
+  `config.rb` (`.cc-os/config` parser), `resolver.rb` (pure repo→board decision:
+  `use`/`activate`/`stop-and-discuss`; no network), `cards.rb` (add-at-Backlog, snapshot,
+  attach_label, comment).
+- CLI: `bin/os-backlog` — `board-ensure`, `activate`, `archive`, `resolve`, `card-add`,
+  `cards`, `snapshot`, `card-label`, `card-comment`; every path fails soft (one-line error,
+  exit 1) when the gem/Planka is unavailable.
+- Skills: `/os-backlog:capture`, `/os-backlog:list` — carry the column-ownership rules (AI
+  creates at Backlog, Doing→Review at most, never Next or Review→Done, never self-assigns
+  `hitl`); list is pull-only per notification policy v2.
+- Agents: `agents/card-triage.md` (priority + autonomy labels only; ambiguity → `hitl`),
+  `agents/board-audit.md` (four drift classes; writes at most comments).
+- Tests: `tests/` — 34 runs/70 assertions against an in-memory `FakePlankaClient`; no live
+  API. Companion os-status check `tracker-configured` (issue #11) validates the `tracker`
+  key grammar and nudges unconfigured git projects (daily-snoozed).
+- Outstanding: Semi slices #14/#16/#17 (routing/migration skill, injection note +
+  /to-issues routing, ops board + rubric category + routing ADR); live verification run on
+  a machine with the gem installed.
