+## Tracker integration (§10)
+
+Closes the task ↔ job round-trip against the platform-service **items API**: a
+tracker Item can become a job, and a job's outcome echoes back to the Item.
+
+```bash
+agent-queue.sh from-tracker <ITEM_ID>   # pull an Item -> materialize a job in inbox/
+agent-queue.sh to-tracker <job>         # echo the job's current outcome to its Item
+```
+
+All HTTP goes through one curl wrapper (`tracker_api`); there are no other network
+calls. Real use needs **platform-service running and a bearer token**.
+
+### Config (env)
+
+| Var | Default | Meaning |
+| --- | ------- | ------- |
+| `AQ_TRACKER_API` | `http://localhost:4003` | base URL of the items API (routes live under `/api`) |
+| `AQ_TRACKER_TOKEN` | _(none)_ | bearer token — **required** for real calls; never hardcode |
+| `AQ_PRODUCT_ID` | _(none)_ | productId (sent as `X-Product-Id`; every Item has one) |
+| `AQ_TRACKER_CWD` | `$PWD` | cwd a tracker-derived job runs in (Items carry no cwd) |
+| `AQ_TRACKER_AUTO` | `0` | `1` = auto-echo on each transition (default OFF — echo is manual) |
+| `AQ_TRACKER_STATUS_INPROGRESS` / `_DONE` / `_FAILED` | `in_progress` / `done` / `wont_fix` | Item status per bucket (the API has no blocked/failed status) |
+| `AQ_TRACKER_API_CMD` | _(none)_ | test seam: a stub that replaces the curl HTTP entirely (selftest uses it) |
+
+### `from-tracker` — Item → job
+
+`GET /api/items/<id>`, then maps fields to job frontmatter:
+
+| Item | Job |
+| ---- | --- |
+| `title` + `description` | job body (verbatim instruction markdown) |
+| `id` | `tracker-item: <id>` and `idempotency-key: tracker-<id>` (stable) |
+| `priority` | `priority:` (label overrides; else Item priority; else `medium`) |
+| label `engine-class:<x>` | `engine-class: <x>` |
+| label `profile:<x>` | `profile: <x>` |
+| label `priority:<x>` | `priority: <x>` |
+| label `cap:<token>` | a `capabilities: [...]` entry |
+
+Idempotent on the derived `idempotency-key` (Slice 1 dedupe) — pulling the same
+Item twice never enqueues a duplicate.
+
+### `to-tracker` — job → Item (one-way echo, §24.5)
+
+Only if the job's meta has a `tracker-item`. Maps the job's stage/result to an Item
+status and `PATCH /api/items/<id>/status`, then `POST /api/items/<id>/comments`
+with a **metrics-only** summary (result, attempts, duration, tokens/cost, +/- lines —
+**never prompt content or secrets**):
+
+| job result/stage | Item status |
+| ---------------- | ----------- |
+| building / review / testing / recovered | `in_progress` |
+| shipped | `done` |
+| failed / timeout / verify_failed / retries_exhausted / capability_mismatch / no_engine / rejected | `wont_fix` (override via `AQ_TRACKER_STATUS_FAILED`) |
+
+Idempotent via `tracker_echoed` in the meta (re-echoing an unchanged outcome is a
+no-op). The echo is **one-way** (child → tracker) and **never authoritative for
+execution**: an echo failure is logged and the job continues unchanged. With
+`AQ_TRACKER_AUTO=1` the worker echoes automatically on each transition; otherwise
+echo is manual. `status` / `insights` surface the `tracker-item` and last echoed status.

 **Layering:** tracker = *WHAT/WHY* (plan, intake, prioritize, roadmap, votes) · gigafactory = *HOW* (execute) · platform-service = shared brain · agent-queue runner = offline edge.

 ### Phase 1 — Adapter (no new infra)
-- [ ] **task → job**: a tracker `Item` of `type: task` (e.g. `assignee: @agent` or label `agent:run`) is exported to a job `.md` (manifest mapped: title/description → body, priority → priority, labels → capabilities/profile hints).
-- [ ] **job → tracker**: lifecycle events post back as **status updates + comments** — `building` → status `in_progress` + comment "started on factory X"; `shipped` → `done` + comment with commit SHAs / PR link / verify results; `failed` → comment with reason (status stays `in_progress` for human triage).
-- [ ] Idempotency: re-running the adapter for the same item doesn't create duplicate jobs (idempotency-key = item id + content hash).
-- [ ] Adapter is a thin script/CLI (`aq from-tracker ITEM-789`) + optional poller.
+- [x] **task → job**: a tracker `Item` of `type: task` (e.g. `assignee: @agent` or label `agent:run`) is exported to a job `.md` (manifest mapped: title/description → body, priority → priority, labels → capabilities/profile hints). *(P1-S4: `aq from-tracker`; labels `engine-class:`/`profile:`/`priority:`/`cap:` → frontmatter.)*

 - **Acceptance:** filing a tracker task, marking it `agent:run`, results in a queued job; on ship, the item flips to `done` with a SHA comment.
 - **Verify gate:** adapter e2e against a tracker-service test instance (or mock); round-trip assertion.
