Implements BB-288.

The learning loop never completed: no wake or brief showed a gu_ id, so no hand-written guidance unit could be cited; trial lessons read as owner to-dos; and a lesson's pull request was merged by its scope, not by the decide list. This renders the ids, moves trial lessons onto the project steward's early-land path, places lesson PRs by the ordinary decide list, and stops the efficacy view blaming guidance before ids ever rendered.

A merge to bb-plugins main moves the pin, builds a new bb-server image and stages a restart for every developer's server (.bb/AGENTS.md, "Shipping a plugin change"). Anyone who never presses Restart now is updated in the quiet window, 03:00–05:00 US Eastern.

Was stacked on #316, which squash-merged to main at 11:54Z; this branch is rebased onto main and the PR is retargeted to it.

Classification

owner-reviewed: the decide-list entry "The stewards plugin outside its authority seams (the app and the sidebar UI, its skills, every other stewards file)" (decide: project) matches the seven changed files, so the project steward approves. No self-widening file (decisions.ts, gate.ts, approvals.ts, approvals-store.ts, .bb/stewards/project.json) is touched, and no approval-recording code is added.

What changes

• wake.ts: a compact ## Guidance units index (id, file, heading, a 120-char snippet) in the binding wake, the brief and the project steward's wake, listing the binding's playbook units before AGENTS.md and placed where fit can clip it, so it never costs the snapshot or "What changed"; the project steward's ## Lessons (trial) block names the early-land command and says trial lessons are not owner to-dos.
• lessons.ts: lessonLandingMark places a lesson by decideForPull on its file (a boundary lesson stays the user's); landLessonInstruction is the one early-land sentence the wake and the record reply share.
• server.ts: wakes and briefs carry the AGENTS.md and binding-playbook units; mergeLessonPr consults the decide list and merges a project-file (playbook) lesson exactly as before, while a user file (AGENTS.md, the project file, roles.json) files the owner's Review PR/Drop item and does not merge; the first gu_ render is stored and bb stewards lessons --efficacy suppresses the "uncited for 90 days" list until 90 days after it.
• skills/stewards/SKILL.md: the landing rule now names the decide list.

Testing

• npm run typecheck: pass.
• npm test: pass (32 files, 1528 tests; not all in the plugins CI matrix).
• New tests: the wake/brief render a gu_ id beside each unit; a realistic 75-unit index lists every id and a 1000-unit one still keeps "## 4. Snapshot" and "## 5. What changed"; the binding's playbook units are listed before AGENTS.md; the project wake names the early-land command and the digest record carries no trial lesson; lessonLandingMark places a playbook lesson project and an AGENTS.md lesson user against the entry BB-280 landed; the server e2e merges a playbook procedure lesson as the project steward's with no bb-approval marker, and files an AGENTS.md procedure lesson for the owner (not merged, Review PR/Drop filed); lessons --efficacy is suppressed before 90 days and lists after.
• Not tested: no live bb-server; the behaviour is unit- and harness-tested.

Review round 1 (Claude Opus 5.5, at e51a81f)

Owner review required: yes. This is stewards plugin code (wake.ts, lessons.ts, server.ts, the stewards skill). The decide-list entry "The stewards plugin outside its authority seams…" is decide: project, so the project steward approves once blocker 1 is fixed. The spec was approved 2026-11-10 03:49Z.

Blockers

1. PR base / file list. stewards: stacked pull requests are visible for their whole life (BB-287) #316 was squash-merged to main at 11:54Z. This PR's base is still that branch, so GitHub diffs 36 files instead of BB-288's 7, including the pre-squash BB-279/280/285/286/287/289 commits. bb stewards gate reads that list: it currently matches approvals.ts, gate.ts (self-widening) and roles.ts/ready-gate.ts/escalations.ts (a user entry), so the gate would route this to the owner. The project steward's guidance to "merge into stewards: stacked pull requests are visible for their whole life (BB-287) #316's branch" now lands nowhere. Fix: retarget to main and rebase e51a81f onto it. I cherry-picked it locally, and the only conflict is the approvals.js import line in server.ts (keep main's line and add recordProjectDecision).
2. wake.ts:637, 1521, 762: the guidance block pushes the wake past its cap. Every unit's full text goes into the wake's head. fit() never clips the head, and when the head alone overflows WAKE_MAX_CHARS it clips head+tail from the end. Measured with this project's real .bb (AGENTS.md has 52 units and 35,009 rendered chars; linear-tickets.md has 23 units and 19,627 chars), a linear-ticket binding wake goes from 11.4K to the 30K cap and loses "## 4. Snapshot", "## 5. What changed" and the closing instruction. The project wake has the same problem: AGENTS.md alone fills its head, so the bindings list and the tail are gone. The brief (injected as per-turn context) grows to its 30K cap on every turn, and bb stewards brief (server.ts:11596, no maxChars) prints about 55K unclipped. AGENTS.md is also already loaded natively into every thread. Fix: render a compact index (id, file, heading and a short snippet, as the efficacy view does), put it somewhere fit can clip (after the snapshot) or cap it, and add a wake.ts test with a realistically sized AGENTS.md asserting that "What changed" survives.
3. server.ts:6027: the "project approval recorded before the merge" path never runs in its e2e test. In "a procedure lesson opens one pull request … and the project steward merges it", t.githubComments is [] after the merge, so no bb-approval is posted. The guard (binding, projectThreadId, a snapshot with a head sha) skips it silently, and reverting the recordProjectDecision call fails no test. Either make the fixture serve the lesson PR's snapshot and assert that the project approval naming the BB-280 playbook entry is posted before the merge, or drop the claim from the PR body and the code comment.

Tested

• Ran: npm run typecheck and npm test in plugins/stewards on e51a81f cherry-picked onto main (pass, 1525 tests; the CI quality_checks (stewards) job shows no conclusion on this head). I also ran throwaway formatWake and server-test probes for blockers 2 and 3, using bb-gate .bb at main.

Review round 2 (Claude Opus 5.5, at 27c00b3)

Blockers

1. wake.ts:1243–1249: most of the binding's own playbook gets no gu_ id. guidanceFor puts AGENTS.md units first, and the cap of 60 then cuts the playbook. With this project's real .bb, AGENTS.md has 52 units and linear-tickets.md has 23, so a linear-ticket wake shows only 8 of its playbook's 23 ids. The overflow line sends the steward to bb stewards lessons --efficacy, but that command lists only uncited units, and none at all during this PR's 90-day suppression. The other 15 ids are therefore nowhere a steward can find them, which leaves criterion 1 unmet for the units most relevant to the binding. Since the block is now clippable, one fix is to list the binding's playbook units first and raise or drop the cap: all 75 units at 120 characters is about 25K, inside the cap. The overflow line must point at something that actually lists ids, or go. Please add a test with more AGENTS.md units than the cap, asserting that every playbook unit's id is shown.

Resolved since round 1

• Blocker 1 (stale base): resolved. The PR targets main and diffs 7 files, and bb stewards gate now matches only the project stewards-plugin entry.
• Blocker 2 (wake overflow): resolved. The block is compact and sits where fit can clip it. With the real .bb, the wake is 22.3K and keeps the snapshot and "What changed". This fix introduced blocker 1 above.
• Blocker 3 (approval untested): resolved. The e2e now asserts that the bb-approval naming the BB-280 playbook entry is posted before the merge.

Tested

• Ran: npm run typecheck and npm test in plugins/stewards at 27c00b3 (pass, 1526 tests), plus a throwaway formatWake probe with bb-gate .bb at main.

Review round 3 (Claude Opus 5.5, at af5f207)

Owner review required: yes. This is stewards plugin code (wake.ts, lessons.ts, server.ts, the stewards skill). The decide-list entry "The stewards plugin outside its authority seams…" is decide: project, so the project steward approves. The spec was approved 2026-11-10 03:49Z.

Suggestions

• server.ts guidanceFor: list the binding's playbook units before AGENTS.md. With the real .bb, all 75 ids are now in the wake, but it is 25.1K against the 30K cap: the guidance block is about 13.7K, not ~9K. The test fixture's snapshot is small, so a real ticket with a few comments or a linked PR leaves only about 5K of headroom. fit then clips the block from the end, which is exactly the playbook ids. Putting them first makes the clip cost AGENTS.md ids, which the thread already has natively.

Resolved since round 2

• Blocker 1 (playbook ids cut by the cap): resolved. The cap and the wrong --efficacy pointer are gone, and every unit's id is listed at the real size.

Tested

• Ran: npm run typecheck and npm test in plugins/stewards at af5f207 (pass, 1527 tests), plus a throwaway formatWake probe with bb-gate .bb at main.

[trotterdylan]

Declined at af5f207, for one change only. Everything else in #319 is fine under the project entry: the gu_ rendering, the efficacy suppression, the wake and brief text, and lessonLandingMark sending AGENTS.md and boundary lessons to the owner.

1. Remove the new recordProjectDecision call (and its import) from mergeLessonPr. It posts a project-steward bb-approval marker on a lesson pull request automatically, with an entry that can be null. That is new code that records a project-steward approval, which the spec approval's addition 2 ruled out and AGENTS.md reserves for the user (no self-widening). A playbook (project-file) lesson merges through mergeLessonPr as it did before, with no marker. If you believe a marker is needed, put it in a separate pull request for the owner, not this one.
2. This change is something the review asked for and it narrows the PR, so no new reviewer round is needed. Push it, wait for green checks, and re-ask for approval on the new head; I'll approve it then.

[trotterdylan]

Approved at 362f406. Since af5f207 the commit only removes the automatic recordProjectDecision call and its import from mergeLessonPr, and puts playbook units before AGENTS.md in guidanceFor, as round 3 suggested. No code path records a project-steward approval any more, so the change no longer touches the user's no-self-widening code. All 22 checks are green. Nothing to add.
