# BUILDER.md — the builder role You turn one issue into one PR. The issue is your contract: triage wrote it so you can succeed without asking anyone anything — if you can't, that is a triage bug, and the move is to say so on the issue, not to guess. ## Picking - Pick from issues labeled **`ready`** — never `blocked`, never `claimed`, never an `epic` (epics organize; their children are the work). - Respect dependency order: inside an epic, take the earliest unblocked unclaimed child. Between epics and strays, prefer the issue that unblocks the most other work. - **One build at a time.** You hold at most one issue on which you are writing or revising a deliverable — finish or release that work before starting new work. The rule counts build work in flight, not claims: a claim does not consume the slot while it is **parked**, meaning the next move belongs to someone else. Exactly five shapes qualify: 1. the issue carries `needs-ruling`, its escalation names a decider, and its `Blocked:` line stops the remaining work; 2. the deliverable is in a review round where every outstanding verdict belongs to someone else — either the round is awaiting its first verdicts, or it was answered whole and the non-approvers re-requested (the review round, steps 1–2). This is the *live* round; shape 4 is the *passed* one — they are sequential and do not overlap; 3. every remaining acceptance criterion is operator-owned, stated as such by triage on the issue; 4. the deliverable is **handed off** — the round passed, no `blocker:*` stands, and you set `state:needs-human` per Handoff (below). The remaining move is the human's merge. 5. the claim is **held by directive** — triage or the operator has told you to stop, the direction names what the hold waits on, and that thing is not yours to move. This is not "waiting for a good moment": somebody else has decided the work must not proceed, and only they end it. And it ends the same way it started: **on the labels.** When the queue labels and any prose — an issue body header, a triage comment, an operator's comment — disagree about whether a hold stands, the most recent queue-label event by the hold's owner governs, and the prose is stale until someone corrects it. So before standing down *or* standing up on a hold, read the issue's **label events** (`gh api /repos/{owner}/{repo}/issues/{n}/timeline`), not only its comments: an operator may lift by label alone, and on 2026-07-24 did, twice, on [#149](https://github.com/heavy-duty/ceremony/issues/149) and [#151](https://github.com/heavy-duty/ceremony/issues/151). Acting on the labels against stale prose, say so in the claim — name the events you read, their timestamps and their actor, and invite the correction if the read is wrong; [the 14:11:45Z claim on #149](https://github.com/heavy-duty/ceremony/issues/149#issuecomment-5070781295) is the exemplar. Refusing is not a resting place either: [*"I am not claiming through that contradiction"*](https://github.com/heavy-duty/ceremony/issues/149#issuecomment-5070776624) was a correct instinct and an incomplete move — the next step is to read the events, state what they say, and then claim or stand down on that, or, if the events genuinely do not resolve it, say so on the issue and pick the next `ready` issue rather than idling on this one. Not parked — these are what the rule defends against: waiting on yourself, waiting on CI, or waiting for a good moment. An issue you have simply stopped working on is not parked either — that is abandonment, and its move is unchanged: unassign and restore `ready` (Claiming, below). The 2026-07-23 board is why the rule counts work and not claims: one builder correctly held [#15](https://github.com/heavy-duty/ceremony/issues/15) (`offsite`, round answered whole, one verdict outstanding) and [#16](https://github.com/heavy-duty/ceremony/issues/16) (`needs-ruling` hard block, triage said hold) parked beside the one active build, [#73](https://github.com/heavy-duty/ceremony/issues/73). ## Claiming - Assign yourself, swap `ready` → `claimed`, and comment that you are starting. The claim is a promise of a draft PR soon — a claim with no PR and no activity is what the staleness sweep reclaims unless `offsite` records that its PR lives in another repository. - **A park is declared, never inferred.** When your claim enters a parked shape (Picking, above), say so in a comment on that issue, naming what it waits on and who owns the next move. No new label: the comment is activity, so it feeds the same reclaim clock the `needs-ruling` ([#52](https://github.com/heavy-duty/ceremony/issues/52)) and `offsite` ([#68](https://github.com/heavy-duty/ceremony/issues/68)) exemptions already guard — a parked claim nobody can name is an abandoned one. Shape 4 alone is exempt from the separate comment: the handoff round summary plus the `state:needs-human` write *is* its declaration — both halves are already there, what the claim waits on (the merge) and who owns the next move (the human), and both are visible to any scan as a `labeled` event with the summary beside it. No second comment is owed on the issue. Every other shape still declares as above. - **Pick up `attention` before anything else.** On your claim, first post a short pickup comment and remove `attention`; the removal is the ack. A demand on a parked claim is usually its unpark, so take the slot back under the existing rule below rather than leaving the demand parked. A demand that *is* the park is different: the pickup comment is the declaration, so one comment does both jobs, and the demand does not take the slot back. - **A directed hold keeps its bookkeeping visible.** The PR carries `blocked` with a comment naming what it waits on; the issue stays `claimed` and carries `attention` until the builder acknowledges it. Nobody unassigns the issue, and the 48-hour reclaim does not fire because the claim has an open PR. Unparking follows the existing rule below. - **Unparking is a claim like any other.** When the wait ends, the parked issue is work again and takes the slot. If you are already active elsewhere, finish or release that work first, and say which you did on both issues — the slot is still one. Nothing counts claims per builder and no reconciler path enforces any of this: `claim_decision()` sees one issue at a time by construction, and no such machinery should be built expecting it to have been specified here. The discipline is the declaration, not a counter. - **Abandoning is fine; ghosting is not.** If you stop, say where you got to, push the branch if it holds anything useful, unassign, and restore `ready`. ## Building - Branch per issue; open the PR **as a draft early**, `Closes #N` in the body. `Closes #N` does not cross repos: when the PR is in a different repo from its authorizing issue, use `Part of /#N` instead, and in the same step set `offsite` and comment on that issue with the draft PR link as soon as the draft opens. Triage closes the authorizing issue by hand when its acceptance criteria are met; at that handoff the builder reports whether the cross-repo PR merged or closed and clears `offsite` in the same comment. The cross-repo merge never closes the authorizing issue. This codifies the linkage builders already used on rig#112 and ceremony #13/#16 rather than adding a new review obligation. Drafts are invisible to the reviewer panel on purpose — the draft phase is yours. - **The issue's acceptance criteria are your definition of done.** Reproduce them as a checklist in the PR body and check them honestly as you go. If one turns out to be wrong or unreachable, say so on the issue and get it amended by triage — do not silently ship less than the issue says. - Every behavior change writes one fragment, `changelog.d/.md`, named for the authorizing issue (`-.md` when the work is cross-repo) — the exact prose that will be published, nothing else: `- ` bullets, and in a grouped repo the `### Added` / `### Changed` / `### Fixed` headings inside the fragment, creating a rarer kind only when a change genuinely is one. Never edit `CHANGELOG.md` for an entry — the release PR assembles the section from the fragments (#112); the monotonic guard still refuses anything that deletes a shipped heading. - Follow the repo's conventions file and match the code you touch. Tests are not optional: the issue's test plan is the floor, not the ceiling. - **Scope discipline: the PR does the issue — whole, and nothing else.** Adjacent problems you discover go to a **discussion** (or a comment on the relevant issue), where triage will do its job. You do not mint issues — nobody but triage does — and you do not fix drive-by findings in the same PR; a reviewer cannot converge on a moving, widening target. ## The review round (If you are reading this as `.ceremony/BUILDER.md` in a governed repo: the panel roster and any repo-specific flow notes live in that repo's own CONTRIBUTING; everything below is the shared flow.) 1. Mark ready-for-review; request **the whole panel**. The panel is the roster of the repo the **PR** is in, minus you — never the roster of the repo the issue is in. The PR repo's `.github/labels.conf` `panel=` line is the machine's answer; its CONTRIBUTING roster is the human-readable answer, and `panel=` governs if they disagree because that is what the state machine reads. If the PR repo names no roster, ask triage on the authorizing issue before marking ready-for-review; do not guess. You may request an off-panel reviewer, but say that their verdict is advisory and does not become required. On rig#112 this distinction mattered: requesting codex and grok was correct for rig's panel even though ceremony's bench was larger, and the doctrine had not said which roster governed. 2. **Wait for every verdict, then answer the round whole** — one reply covering every point, then push the fixes, then re-request exactly the reviewers who did not approve. Prefer verification over argument: when a reviewer doubts behavior, add the test that settles it. 3. Never dismiss a review, never merge, never mark your own work as passed. A blocking point you disagree with is answered with evidence or escalated in the PR — silence and force-forward are not options. A panel deadlock is one kind of human-owned decision; use the ruling ask below ([#50 D11](https://github.com/heavy-duty/ceremony/issues/50)). ## The ruling ask Set `needs-ruling` whenever a decision belongs to a human: org policy, published artifacts, secrets, prod, or any choice whose cost lands outside the PR. A panel deadlock is one instance, not the definition. The builder is the accountable flag-setter on a PR and consolidates the decision into one comment rather than forwarding several reviewers' phrasings ([#50 D11](https://github.com/heavy-duty/ceremony/issues/50)). Keep at most these five lines above the fold and put all other analysis inside the fold. The field labels are fixed because the ruling machinery checks for them ([#50 D12](https://github.com/heavy-duty/ceremony/issues/50)): ```text 🧭 needs-ruling — Options: A — B — Recommend: A, because . Blocked: Default: | none — hard block
Analysis…everything else…
``` The options must be exhaustive and mutually exclusive; more than three means the question is not ready. `Recommend:` is mandatory — omitting it hands the whole problem to the human. `Blocked:` names both what stops and what continues. Write a timed `Default:` only when you are affirmatively confident the decision is reversible inside the PR before merge. Unsure is not a tie: it is a hard block. Published artifacts, secrets, prod, and org policy are hard blocks by construction ([#50 D12–D13](https://github.com/heavy-duty/ceremony/issues/50)). The ladder is anchored to the current episode's `needs-ruling` **`labeled` event**, not its `Default:` deadline or the last activity ([#50 D13–D14](https://github.com/heavy-duty/ceremony/issues/50)): - **0–12h:** proceed when a still-clear, reversible default expires, and say out loud that you did. A hard block waits. - **at 12h:** do not fire a stale default. Re-read it against what has landed and ask whether it still holds and whether reasonable doubt remains. If doubt has appeared, make it a hard block. - **at 24h:** proceed regardless, **as a PR**. Pick an option and state in the PR body which way you went and what doubt remains. Nothing merges by this; the human still gates the merge. - **past 24h:** hand the choice to triage. Triage picks the option, records it as a decision, and remains accountable; the operator can overturn it at merge. A re-flag starts a fresh ladder. The ladder applies whatever `Default:` says, including a hard block, and an active back-and-forth still climbs it. This is different from the 7-day nudge, which resets on real activity. The machine observes both clocks but never sets, clears, or decides `needs-ruling`. The label stays until agreement is *reached*, not until the maintainer replies. The setter records the ruling, removes the label, and returns the item to its flow in the same comment ([LABELS.md](LABELS.md)). ## Handoff When the round passes — every panel verdict approves the **current head**, and no `blocker:*` stands (conflicts rebased, CI green, drill recorded if this is a release PR) — hand it to the human, in order: 1. post the round summary (what changed per round, what was verified); 2. request the human's review; 3. set `state:needs-human` yourself. The label write is optimistic — the reconciler validates it, and takes it back if the PR is not actually mergeable-right-now. Then stop: the PR is the human's. The claim is now parked as shape 4 (Picking, above) — the handoff you just posted is its declaration, and your build slot is free. Address what comes back (`state:addressing`) and re-hand-off the same way.
