Finishes quest/m0/benchmark/breakage.md: every breakage quest knows of is recorded against the PR that caused it, along with that PR's tier, size, writers, and local reviewers. Records go to Kixel Code's store beside the session records, and quest usage lists them.

Changes

• BreakageRecord (src/core/breakage.ts, exported from quest/core): repository, culprit (number, merge instant, tier, size, writers, local reviewers, all read from the culprit's own body), fix or incident, found (check, reviewer, queue, canary, person, customer, or null when unrecorded), and at. parseBreakage is strict, like parseRecord. A fix's breakage is keyed by culprit and fix. An incident's is keyed by its ID, so a resend replaces it.
• Upload: RecordUpload gains breakages, so the body is now {"records": [...], "breakages": [...]}. parseUpload requires the field and refuses a breakage sent twice. SessionRecord is unchanged.
• Sender: each pass also sends one breakage per culprit that a merged PR in its window names under ## Caused by. A culprit older than the window costs one REST read. A link to a PR that does not exist (404) names no culprit, so one bad body cannot block every record. Each endpoint and repository keeps a cursor of its last successful read, so a fix merged after its sessions were sent, as through the merge queue, goes with the next session there.
• quest records incident <id> --found <by> [--pr N] [--at instant] (--at needs a date and time with Z or an offset): posts one breakage right away and fails loud on anything but a 2xx, so a deploy or alert can call it. Without --pr, the incident stays open. Reporting the same ID again with --pr closes it on its culprit.
• quest usage: adds a Breakages section and a breakages field in --json. It lists each culprit named by a merged fix in the window, even one older than the window, with its tier, size, writers, reviewers, who found it, and how long after the merge the fix was opened.
• causes now goes through culprits, which also reads the (found by customer) suffix the rule now asks for, with an optional article.
• The strict field checks moved to src/core/parse.ts so the two record parsers share them. instant now refuses impossible calendar days, such as February 30.
• Deletes the quest and its links in guardrails.md, risk-tier.md, and reviewer-eval.md. That unblocks reviewer-eval.md.

Public API and wire impact

• Breaking change to the wire: an upload must carry breakages (it can be empty). Migration: kixel-ai/kixel.quest's store takes the new parseUpload from quest/core and keeps breakages by breakageKey. Nothing is in production yet.
• New exports from quest/core: BreakageRecord, Culprit, Seat, FINDERS, Finder, parseBreakage, and breakageKey.
• New CLI subcommand quest records incident. quest usage and its --json gain breakages.

Decisions

• Should agents record who found a breakage? ✅ Add the finder clause to assets/CONTEXT.md's ## Caused by rule: end a culprit's line with (found by check|reviewer|queue|canary|person|customer) when known (rejected: leave it out, so only incidents name a finder). Decided by the maintainer in this comment. To keep the hook context under its 10,000-character limit (now 9,985), this PR also tightens wording nearby without changing what it means: the ## Caused by paragraph itself, the reminder to confirm a PR is still open before pushing, and the read-only CI paragraph. docs/context.md mirrors the change.
• How does a fix close an open incident? ✅ A culprit line in ## Caused by names the incident as (found by …; incident <id>), either part optional, and the fix's record replaces the open incident as one record (rejected: land as is and let the store join by culprit; leave linking to the kixel.quest follow-up). Decided by the maintainer in this comment. The rule in assets/CONTEXT.md now reads (found by check|reviewer|queue|canary|person|customer; incident <id>), each part when known. The hook context stays under its 10,000-character limit.
• Design checkpoint after review round 3, which found that a fix naming two incidents of one culprit closed only the first? ✅ Continue: read each ## Caused by line by culprit and incident together (rejected: give each incident a ## Caused by bullet of its own; merge as is). Decided by the maintainer in this comment. A culprit's line naming no incident is dropped when another of its lines names one, so its breakage isn't counted twice.

Open incidents

quest records incident <id> without --pr records an incident as open. There are two ways to close it:

• The reporter closes it: report the same ID again with --pr N.
• A merged fix closes it: the fix's ## Caused by line for the culprit ends with (incident <id>), alone or as (found by canary; incident <id>). The sender then sends the fix's breakage under the incident's ID, so it replaces the open incident as one record holding the culprit, the fix, the incident, and the finder. That removes the double count Pullfrog found.

Fix records sent this way carry the fix's opening as at. BreakageRecord's doc asks the store to keep the incident's earlier at, and its finder when the fix names none. When several fixes name one incident, the one updated last wins, so no upload carries an incident twice. One fix closes several incidents of a culprit with one line for each. An incident nobody names stays open, and the store counts open incidents separately.

Choices made without asking

• Culprit facts travel in the record. The store does not have to parse PR bodies; quest already does. Online reviewers and CI checks are left out: the store's forge index already reads them, and reading them here would cost GraphQL calls on every pass.
• Reverts and red queue or default-branch runs are not sent. The plan leaves them to Kixel Code's forge index. A revert PR that names its culprit under ## Caused by is still counted here.
• When a breakage was found is when its fix PR was opened. A fix counts only once it merges, as quest usage already treated it.
• Incidents go only to the store. quest usage reads GitHub alone, so it never shows them. The store counts open incidents separately.
• quest records incident uses only the token in ~/.config/quest/records.json, with no token in an environment variable. That keeps the token bound to its endpoint. A CI job writes the file.
• No per-class rate is reported. Classes of change don't exist until tier guardrails defines them. The per-tier rows already show sample sizes (PRs, merged, later fixed).

Validation

• just check and just test pass (1321 tests). New tests cover: parseBreakage keeping and refusing records; parseUpload deduplicating breakages; culprits reading the finder; the sender's upload carrying an older culprit read from GitHub; quest usage text and data with a culprit outside the window and a 404 link; incidents opened, closed, refused (403), missing a token, or with no endpoint.
• Ran the real surface, quest usage --since 2026-11-06 on this repository. It listed 15 breakages, including culprits older than the window. I checked two against GitHub directly: feat(usage)!: cost and first rounds per writer and reviewer cell, for the routing charts #721's ## Caused by names feat(usage)!: price sessions through token-max, across SSH hosts #704; feat(usage)!: price sessions through token-max, across SSH hosts #704 merged at 00:04:55Z and feat(usage)!: cost and first rounds per writer and reviewer cell, for the routing charts #721 opened at 00:06:47Z, which the report shows as "2m after merge". quest land: a failed fixer's handback quotes the gate's failure #627 names feat(land): keep the fixer's output and real exit code #312 and feat(land): quest land watch fixes each PR the merge queue drops and re-enqueues it #389, and both appear.
• Ran the built dist/quest.js records incident against a loopback receiver that checks each body with parseUpload. The open report and the --pr 704 close both parsed, the second carrying feat(usage)!: price sessions through token-max, across SSH hosts #704's size, writer, and reviewers. --found luck exited 2, and a missing PR and a missing token each exited 1.

Caused by

No single PR: this is new recording, not a fix.

Follow-ups

• Recommended to plan in kixel-ai/kixel.quest: store breakages by breakageKey, join reverts and red runs from its forge index, and show open incidents separately on the factory page. That repository owns the store, so the work does not belong here.

Maintainer decision (2026-11-14, /quest-run): who found a breakage

• ✅ Add it: the ## Caused by rule in assets/CONTEXT.md asks agents to end each line with (found by check|reviewer|queue|canary|person|customer) when known, in this PR, keeping the file under its 10,000-character limit.
• Rejected: leave it, so only incidents say who found them.

Follow-up: a quest in kixel-ai/kixel.quest for the store to keep breakages, join reverts and red runs, and show open incidents separately will be planned at the end of this run, not in this PR.

Important

The code is sound and the targeted tests pass, but only the reporter can close an incident. Nothing lets a fix PR close one. The deleted quest's Plan expected the fix's ## Caused by to close it, and this PR drops that without saying so.

Reviewed changes

The full PR: breakage records, the wire format change, the sender and incident command, the quest usage section, and the ## Caused by rule change.

• BreakageRecord and parseBreakage (src/core/breakage.ts) — a strict parser that holds a culprit's tier, size, writers, and reviewers. A fix's record is keyed by repository, culprit, and fix; an incident's by repository and ID.
• Shared strict parser (src/core/parse.ts) — parseRecord's field checks moved here, and parseUpload now requires breakages and refuses duplicates by breakageKey.
• Sender (src/cli/send.ts) — each upload carries fixBreakages for the merged PRs it read. A per-group read cursor (readCursor/writeCursor, written only after a 2xx) widens updatedPulls, so a fix merged after its sessions were sent still goes with the next session.
• quest records incident — posts one breakage right away and fails on anything but a 2xx. It resolves cwd before questRoot and reads the culprit with readPull (a 404 means no such PR).
• quest usage — a new Breakages section and --json field. Culprits older than the window are read from GitHub, and a narrowed report keeps a breakage when its fix or its culprit is reported.
• ## Caused by rule — assets/CONTEXT.md and docs/context.md change together and add the (found by …) finder. culprits reads it, allowing an optional article. assets/CONTEXT.md is 9,800 characters.
• Quest cleanup — deletes breakage.md and its links in guardrails.md, risk-tier.md, and reviewer-eval.md, which also drops reviewer-eval.md's ## Required.

I ran test/records.test.ts, test/send.test.ts, and test/usage.test.ts: 71 tests pass.

⚠️ Open incidents can't be closed by the fix, and closing one counts the breakage twice

The deleted Plan said: "An incident whose culprit is unknown is recorded open, and the fix's ## Caused by closes it." As built, only re-running quest records incident <id> --pr N closes an incident. The deploy or alert that opened it rarely knows the culprit, and the person who later finds it writes a fix PR, which has no way to name an incident. So the store's open-incident count can only grow. When someone does close an incident with --pr 42, and fix #50 also lists #42 under ## Caused by, the store gets two records for the same failure: [repo, "<id>"] and [repo, 42, 50]. Neither ## Choices made without asking nor ## Decisions mentions this change, and the quest that held the plan is deleted in this PR, so the gap would go untracked.

Technical details

# Incidents have no path to close from a fix, and a closed incident double-counts

## Affected sites
- src/cli/send.ts `reportIncident` — closing an incident requires the reporter to re-report with `--pr`
- src/cli/breakage.ts `culprits` — a `## Caused by` bullet can't name an incident ID
- src/core/breakage.ts `breakageKey` — an incident and a fix naming the same culprit get separate keys, so the store keeps both
- README.md "A deploy or alert reports what it found…" paragraph — documents re-reporting as the only way to close an incident

## Required outcome
- Either a fix PR can close an open incident and the two count as one breakage, or the PR records that it dropped the Plan's mechanism and either a quest here or the kixel.quest follow-up owns linking incidents to fixes.

## Open questions for the human
- Should `## Caused by` gain an incident reference, for example `(incident <id>)` on the culprit line, so that `fixBreakages` sends the fix's breakage under the incident's key?
- Or should the store join incidents to fixes by culprit, accepting that an incident with no culprit stays open until someone runs `--pr`?

Agreed, the gap is real: this PR lets only the reporter close an incident, which drops the Plan's "the fix's ## Caused by closes it". A fix can't name an incident without a new ## Caused by format, and that format is the maintainer's decision, so I haven't guessed one. The PR body's ## Open incidents section now explains what happens to open incidents and the double count, and ## Waiting lists the options, recommending an incident <id> part in the culprit line's parenthesis.

Maintainer decision (2026-11-14, /quest-run): how a fix PR closes an open incident

• ✅ The fix names the incident: a ## Caused by line can carry (found by …; incident <id>), each part when known, and the fix's record replaces the open incident as one record, as the quest's Plan described.
• Rejected: land as is and have Kixel Code's store join a closed incident and a fix by culprit.
• Rejected: land as is and leave linking to the kixel.quest follow-up.

Walkthrough

The change adds validated breakage records for fixes and incidents. The usage report derives breakages from merged pull requests’ ## Caused by sections and displays culprit details and timing. Session uploads now include breakages and track a pull-request read cursor. A new quest records incident command posts incident records to the configured endpoint. Documentation and tests are updated for attribution, uploads, and incident reporting.

Merge Risk: Low · up to 36b04

This change adds breakage records, incident reporting, and upload support. The remaining problems are narrow: some invalid timestamps are accepted, and narrowed usage reports do extra work and can fail on unrelated pull request reads. These are worth fixing but do not block merging.

[pullfrog]

✅ No new issues found. The prior review's concern is addressed: a merged fix's ## Caused by line can now close an open incident, and the fix's record replaces the incident under one breakageKey, so nothing is counted twice.

Reviewed changes

The changes since the prior Pullfrog review (36b047b..6d1c41f): a fix can now name the incident it closes.

• culprits reads (found by …; incident <id>): the closing parenthesis on a culprit's line may hold the finder, the incident, or both, and Cause gains incident.
• fixBreakages sends under the incident's key: a fix's breakage carries cause.incident and is deduplicated by breakageKey. The first copy is kept, which is the most recently updated fix because updatedPulls lists newest updates first, so parseUpload never sees one incident twice.
• parseBreakage allows a fix and an incident together: it now refuses only a record that has neither, and BreakageRecord's doc asks the store to keep the incident's earlier at and its finder.
• The rule, docs, and output: assets/CONTEXT.md and docs/context.md change together (9,814 characters, under the hook limit). The README and --help describe closing an incident this way, and quest usage prints closing incident <id>.
• Tests: cover parsing the parenthesis, round-tripping a fix that closes an incident, parseUpload refusing an open incident sent with its closing fix, and the sender sending one record when two fixes name the same incident.

I ran test/records.test.ts, test/send.test.ts, and test/usage.test.ts: 72 pass. The remaining edge case, one fix closing two incidents of the same culprit, is already listed in the PR body's ## Waiting, so I did not raise it again.

Maintainer decision (2026-11-14, /quest-run): round-3 design checkpoint

• ✅ Continue: read each ## Caused by line by culprit and incident together, so a fix naming two incidents from the same culprit closes both, with a test and one more review round.
• Rejected: give each incident its own ## Caused by bullet, a new format and another assets/CONTEXT.md edit.
• Rejected: merge as is and close the second incident with quest records incident <id> --pr N.

(Written by Claude Opus 5.5)

[pullfrog]

✅ No new issues found. A fix naming two incidents of one culprit now closes both, which was the edge case left over from the prior review.

Reviewed changes

The change since the prior Pullfrog review (6d1c41f..6a04878): culprits now reads each ## Caused by line by culprit and incident together.

• culprits dedups by culprit and incident: the key is [number, incident], so each pair keeps its first line, and one fix can close several incidents of one culprit.
• A culprit's line naming no incident is dropped when another of its lines names one, so the breakage isn't counted twice.
• causes returns each PR number once: it deduplicates the numbers, and usage.ts callers that attribute by number don't double count.
• fixBreakages is unchanged: its breakageKey dedup still stops one incident from being sent twice.
• Docs and tests: the README and the culprits doc comment describe the new behavior. A new test covers two incidents of one culprit, the dropped plain line, a repeated incident, and causes returning [7, 8].

I read the diff and the fixBreakages consumer. I did not run the tests.

✅ No new issues found. The two CodeRabbit concerns are addressed: --at now rejects bare dates, times without an offset, and impossible days, and a narrowed report no longer reads culprits it would drop.

Reviewed changes

The changes since the prior Pullfrog review (6a04878..03b356b):

• Calendar-valid instants in records: parse.ts's instant now refuses an impossible day such as February 30 and still takes leap days.
• Stricter --at for quest records incident: the new parseInstant in send.ts requires a date, a time, and a Z or offset on a real calendar day. The help text and README say so.
• Narrowed reports skip unneeded culprit reads: fixBreakages takes a FixSources object with an optional only set. It skips a cause before readPull when neither its fix nor its culprit is reported, instead of filtering afterward.
• Tests: cover the leap day and February 30 in parseBreakage, parseInstant's accepted and refused forms, and a narrowed quest usage making no /pulls/N reads.

I ran test/records.test.ts, test/send.test.ts, and test/usage.test.ts: 74 pass.
