+### Retire the Plane wire names — they outlived the adapter
+
+The 2026-08-18 cutover deleted the Plane adapter but left its vocabulary in
+live code. The cosmetic half is done (see Done, 2026-08-19); what remains are
+names that are **not** cosmetic because something outside the process reads
+them, so each needs a compatibility shim rather than a rename:
+
+  - `plane_task_id` — `pr_review_watcher/main.py` reads it out of the
+    **on-disk review state** (`state.get("plane_task_id")`, ~8 sites). A bare
+    rename orphans every in-flight review at the moment it deploys.
+  - `plane_issue_id` — written into **proposer artifacts** and read back by
+    `decision/service.py` (`item.get("plane_issue_id")`). Same problem across
+    artifacts already on disk.
+  - `"plane"` as an **alert channel name** — `observer/alert_channels.py`
+    (`self.name = "plane"`), and `alert_config.py` both validates against
+    `{"operator_log", "plane", "slack", "pagerduty"}` and ships four default
+    routes using it. Operator alert config names this channel, so renaming it
+    is a config break.
+  - `entry["plane"]` — an emitted key in the `custodian_sweep` report.
+
+Shape of the fix: write the new key, read both, drop the old read a release
+later. Worth doing — `plane_task_id` in a Forgejo-only system actively
+misleads — but it is a migration, not a cleanup.

+### 2026-08-19: Plane leftovers swept, and two Up Next items closed as already-done (✅ COMPLETE)
+
+Follow-up to the cutover. Three separate things, all found by asking why the
+codebase still says "Plane" 2,000 times.
+
+**Cosmetic leftovers removed** (no behavior change — every rename below had
+exactly one importer or none):
+
+  - `propagation/plane_adapter.py` → `board_adapter.py`, `PlaneTaskCreator` →
+    `BoardTaskCreator`; sole importer is `entrypoints/propagate/main.py`.
+    Docstrings in `propagator.py` referenced `PlaneClient.create_issue` — a
+    class deleted in #521.
+  - `tests/test_plane_parsing.py` → `test_task_parsing.py`. It never tested
+    Plane; it tests `TaskParser`.
+  - `docs/design/plane_kodo_wrapper.md` → `docs/history/plane-kodo-wrapper.md`,
+    `status: implemented` → `superseded`. It sat in `design/` (live docs)
+    describing both a retired board and a retired engine.
+
+**A real bug behind one of them.** `config/plane_task_template.example.md` was
+a stale copy of what `render_task_template()` generates (it still told the
+operator to describe the change "you want Kodo to make"). Nothing read it —
+`oc setup` writes `config/task_template.local.md`. But `.gitignore`,
+`docs/operator/setup.md`, and **both secrets scripts** still pointed at the
+dead `plane_task_template.local.md` path, so `backup-secrets.sh` was backing
+up a file that never exists and the template the operator actually has was in
+no backup at all. All four repointed at the real path; the stale example
+deleted. Also dropped three `.gitignore` entries for `deployment/plane/**` and
+`tools/report/kodo_plane/` — none of those directories exist.
+
+**Both Up Next items were already done, just unrecorded:**
+
+  - *CI runs ~1,830 fewer tests* — closed by #525, and the coverage survived
+    the #527 port: `.forgejo/workflows/ci.yml` job `test-rest`
+    ("Test (suites outside tests/unit)") runs `pytest -q tests/ --ignore=tests/unit`.
+  - *`audit` on Forgejo Actions* — the runner is installed and registered
+    (`forgejo-runner` container up, Actions jobs executing), the workflow is
+    ported as `.forgejo/workflows/custodian-audit.yml`, and live branch
+    protection on `main` requires
+    `['custodian-audit / audit (pull_request)', 'reviewer-verdict']` with
+    `apply_to_admins: true`. Note the spec's "identical context name"
+    requirement was met the other way round — the required-context list was
+    updated to the Forgejo name rather than the name being preserved. The
+    cutover is live: `pr_backend: forgejo` in `operations_center.local.yaml`.
+
+What was deliberately **not** touched: the Plane names that are wire formats
+(`plane_task_id`, `plane_issue_id`, the `"plane"` alert channel). Those read
+persisted state and operator config, so they need a shim, not a rename — see
+Up Next.

+## 2026-08-19 — Plane leftovers: a dead name is only cosmetic until something points at it
+
+Swept the Plane vocabulary the cutover left behind. Most of it was what it looked
+like — a module, a class, a test file and a design doc named for a system that no
+longer exists, each with one importer or none. Details in `.console/backlog.md`.
+
+One wasn't cosmetic. `config/plane_task_template.example.md` was dead in the sense
+that no code read it — `oc setup` writes `config/task_template.local.md` from
+`render_task_template()`. But `.gitignore`, `docs/operator/setup.md`,
+`backup-secrets.sh` and `setup-secrets.sh` all still named the old
+`plane_task_template.local.md` path. So `backup-secrets.sh` has been faithfully
+backing up a file that cannot exist, and the template the operator actually has
+was in no backup at all. The lesson generalises past this file: **grep for the
+name before calling it unused — "nothing reads it" and "nothing references it"
+are different claims,** and the gap between them is where silent data loss lives.
+
+Deliberately did not rename the Plane names that are wire formats:
+`plane_task_id` (read from on-disk review state), `plane_issue_id` (read from
+proposer artifacts), and `"plane"` as an alert-channel name (validated against
+operator config). Those are a write-both/read-both migration, not a cleanup;
+filed in Up Next. Renaming them in place would have orphaned every in-flight
+review at deploy time.
+
+Process note, and it is a trap worth remembering: **the fleet executes out of the
+live working tree.** Every supervisor runs
+`/home/diane/GitHub/OperationsCenter/.venv/bin/python -m operations_center...`
+with `cd` into that checkout and re-execs its child every 30s, so editing `src/`
+there — or switching its branch — changes what the running fleet does on the next
+restart. Did the work in `git worktree` at `~/GitHub/oc-plane-cleanup` instead.
+That collides with the already-recorded worktree trap (a worktree has no venv and
+no editable install, so bare `python` there measures the *main* checkout);
+defeated it by running the main venv's interpreter with
+`PYTHONPATH=<worktree>/src`, and **proved** it rather than assuming —
+`operations_center.__file__` resolved to the worktree before running anything.
+67 targeted tests pass; ruff clean.

 ## Purpose
 
 Build a self-hosted AI execution wrapper that uses Plane as the Jira-like board and [Kodo](https://github.com/ikamensh/kodo) as the coding engine, with explicit repo and base-branch selection per task.
