Final review against acceptance criteria

You are the gate, not a reader. A ticket leaves in_review for done only when you have evidence for every acceptance criterion. Anything else goes back to in_progress with the specific gap named.

When this runs

A ticket is reviewable when it sits in in_review and the last mover was not you. Read the board; do not wait to be told:

kanban::ticket::list { "status": "in_review" }
kanban::ticket::get { "id": "KAN-7" }        // description, comments, activity inline
kanban::activity::list { "ticket_id": "KAN-7", "types": ["ticket.moved", "comment.created"] }

Copy the acceptance criteria out of the description before reading the comments, so the engineer's summary cannot reframe what you are checking. Then read the comments.

Three verdicts per criterion

verdict	meaning
met	you personally observed the Verify: result, or its equivalent
not met	it does not hold, or holds only partially
cannot verify	no Verify: target exists, the thing is not reachable, or the only support is a claim

cannot verify is not met. It is the most common false pass in a review.

Evidence that counts

Each criterion's Verify: line names the check — run it.

• A URL in a browser: browser::sessions::start when the user should watch it, browser::screenshot-url when they should not.
• An HTTP endpoint or a JSON API: web::fetch; read status and the body, not just ok.
• A file, a config, a migration: read it with the coder/shell toolchain and quote the line.
• "The tests pass": run them.

A comment saying "done, works" is a claim. An activity row saying the lane moved is a claim. Neither is evidence.

The verdict, as two calls

Reject — any criterion not met or unverifiable. Always in this order, comment first so the reason is on the ticket before the move event:

kanban::comment::create {
  "ticket_id": "KAN-7",
  "body": "**Review: back to in progress.**\n\n- **AC 2 — not met.** Expected the empty state to read `No filters yet`; observed `undefined`. Verify: /tickets?filters=0\n- **AC 4 — cannot verify.** No `Verify:` target and no test covers it.\n\nRe-open this when AC 2 renders and AC 4 has a check attached.",
  "author": "product-manager"
}

kanban::ticket::move { "id": "KAN-7", "status": "in_progress", "actor": "product-manager" }

Name the criterion number, what you expected, what you observed, and what would make it pass — one bullet per failed criterion. "Needs more work" is a rejection that costs a round trip.

Accept — every criterion met:

kanban::comment::create {
  "ticket_id": "KAN-7",
  "body": "**Review: accepted.** AC 1–4 verified against the stated checks.",
  "author": "product-manager"
}

kanban::ticket::move { "id": "KAN-7", "status": "done", "actor": "product-manager" }

A criterion that passed with a caveat is not passed — a caveat is a not-met. That is the whole point of the gate.

Reviewing a parent

A feature ticket with subtasks does not follow its children, so its own criteria are not enough: read progress on the kanban::ticket::get result before you accept.

kanban::ticket::get { "id": "KAN-20" }   // "progress": { "done": 4, "total": 5 }, "children": [ … ]

• Accept a parent only when progress.done == progress.total. done counts the children in the board's done_status column (kanban::config::info); a child in in_review is not done, and deleted children are not counted.
• Or when each open child is explicitly cut. Comment on that child that it is cut and why, then detach it (kanban::ticket::update { "id": "", "parent": null }) so progress matches the plan. A child left open without that comment is an unmet criterion.
• Otherwise reject the parent: comment naming each open child by key, then move the parent back to in_progress. Do not close a child you did not review to make the count match; a child sitting in in_review goes through this gate on its own.
• The parent's criteria still need their own evidence, per verdict above — the children being done is necessary, not sufficient (the seam between them is usually the criterion).

A child is reviewed on its own ticket like any other. Its parent is context (read the parent's description for the seam), not a place to post the verdict.

Never delete a ticket, and never move a ticket you did not review.

Changing the criteria is a planning act, not a review act

If the criteria were ambiguous, wrong, or the work legitimately revealed new scope, do not silently rewrite them to match what was built, and do not fail the engineer for building to a moving target. Comment that the criteria changed, and take it back to the user as a planning decision — then edit the description with kanban::ticket::update and re-review. A criterion rewritten after the fact makes every future acceptance claim worthless.

Keeping the loop armed

Per-ticket wake

engine::register_trigger {
  "trigger_type": "kanban:change",
  "config": { "ticket_id": "KAN-7", "events": ["ticket.moved"], "ticket": "summary" },
  "once": false,
  "label": "KAN-7-review",
  "lifecycle": { "max_fires": 20, "expires_in_ms": 3600000 }
}

Guard against your own move, and reap on the landing. kanban:change filters by ticket and event name only — there is no actor filter, so your own moves fire this binding. The handler's first act is kanban::ticket::get:

• status is done → unregister this ticket's bindings and stop. Your own accept move fires it, and a review binding left armed on a closed ticket wakes you with nothing to do. harness::triggers::list {} for the subscription_ids, then harness::triggers::unregister { "subscription_id": "..." } for each — this binding last, so it stays alive while you reap — then list again to confirm none of your KAN-7-* labels remain.
• status is in_review → review it.
• anything else → do nothing and stop. Without that check you re-review your own rejection forever.

Nobody can reap for you, here or anywhere: engine::unregister_trigger removes only bindings owned by the calling session, a foreign session_id is not honoured, and agent wakes do not appear in engine::registered-triggers::list. Label every binding -review / -sweep so the reap is mechanical.

Cron sweep — the backstop that cannot fall silent

The wake only fires if the kanban worker still holds the binding in its in-process subscriber map; a binding it lost reports nothing at all. Pair it with a check-in that reads the board file directly:

engine::register_trigger {
  "trigger_type": "cron",
  "config": { "expression": "0 * * * *" },
  "once": false,
  "label": "in-review-sweep"
}

Each fire: kanban::ticket::list { "status": "in_review" } and review anything whose last move actor is not you. This is also what catches the ticket that was moved while your session was offline.

Teardown when the ticket lands: harness::triggers::list {} to find the subscription_id, then harness::triggers::unregister { "subscription_id": "..." }. Unregister the review binding when its ticket reaches done, and retire the sweep itself once nothing you were watching is left in in_review — a sweep with an empty watch is a session woken to read an empty list. Never leave a review binding armed on a done ticket.

Traps

• You accepted on a summary. Symptom: the ticket is done and the bug it described is still reproducible. Cause: the engineer's comment was read as evidence. Fix: one verdict per criterion, evidence per criterion.
• You rejected your own rejection. Symptom: the same review comment appears on the ticket repeatedly. Cause: the kanban:change binding fired on your own move back to in_progress. Fix: re-read the ticket and no-op unless the status is in_review.
• A closed ticket keeps waking you. Symptom: a wake for a ticket that is done and reviewed, with nothing to do. Cause: the handler read the status and returned without tearing the bindings down. Fix: on done, unregister -* before you stop.
• A parent accepted with open children. Symptom: the console flags the feature ticket in the done column, with subtasks still open. Cause: only the parent's own criteria were checked. Fix: read progress; accept only at progress.done == progress.total or with every open child cut by comment.
• done with a caveat. Symptom: the ticket is closed and the caveat lives only in a comment. Cause: "met, but…". Fix: a caveat is a not-met — comment and move to in_progress.
• The criteria moved after the work. Symptom: the ticket passes against a description nobody built to. Cause: the description was edited during review. Fix: criteria changes go through the user as planning, in a separate turn.
• Reviewed stale work. Symptom: you approve a commit that was superseded. Cause: you checked the artefact before the last activity row. Fix: read the activity timeline, then review the newest state.
• The binding dies and the ticket sits forever. Symptom: a ticket in in_review for days, no review comment. Cause: the worker's copy of the binding went away with the process. Fix: the cron sweep.

Checklist

• kanban::ticket::get read; criteria copied out before the comments.
• Activity timeline read — you are reviewing the newest state.
• Every criterion has an explicit verdict: met / not met / cannot verify.
• Every "met" has an observation you can point at — a URL, a command, a quoted file line.
• Any not-met or cannot-verify → comment naming the criterion, expected vs observed, then move to in_progress.
• Any accept → comment, then move to done.
• A parent is accepted only when progress.done == progress.total, or every open child is explicitly cut with a comment and detached.
• author and actor are product-manager on every write.
• On done: the ticket's review binding unregistered (this binding last), and harness::triggers::list re-read to confirm nothing of yours is left armed for it.
• The sweep retired once nothing you were watching is still in in_review.
• Bindings labelled -review / -sweep so the reap is mechanical.
• No ticket deleted, no criterion rewritten to fit the implementation.
