The reply chain is what - lets the `thread-reconciler` weigh the author's response, and `url` is what lets the - re-review accountability section (Step 6) link each still-open thread to its prior - comment. -- `/tmp/gh-aw/review/human-threads.json` — the `{path, line}` of every **unresolved - thread started by a human** (any author other than `github-actions[bot]`). These - are never resolved or replied to; they mark lines where a human review conversation - is already open, so the bot defers there (Step 5). - -The **router** -(above) already decided the routing — team ownership is in `routing.json`, -`lensesToSpawn` names the path-triggered specialist lenses to dispatch, and -`enabledReviewers` names the opt-in reviewers the repo has turned on (none of -either run by default; a reviewer earns its `enable` line through the eval suite, -not by shipping). Dispatch the default reviewers (`correctness-reviewer`, -`skill-auditor`, `thread-reconciler`) **plus** every reviewer named in -`enabledReviewers` **plus** every lens named in `lensesToSpawn`, all **in parallel** -(one turn), and wait for all. If `runBudget.maxReviewerInvocations` cannot fit -that whole set, fill the slots by the dispatch ranking (the budget rule below: -Step 3, graceful-landing bucket 1): defaults first, then matched lenses, then -the targeted opt-in dimensions, then the generic ones. Never choose arbitrarily, and record every -reviewer left undispatched as a planned shed (Step 6 note). - -**One candidate contract.** Every finding-producing reviewer returns `findings[]` -in the same shape (a `label` per finding, from the fixed label set in Step 4); a -specialist lens returns the structured finding schema instead, and the deterministic -normalization step below converts each lens finding into that same label-bearing -candidate shape before anything downstream sees it. What each one reviews and how is -its own definition's concern, not yours: treat all candidates **cumulatively and -identically**, whoever produced them — they feed the scope filter (below), -validation (Phase 3), the verdict (Step 4), and the inline comments (Step 5) -through the exact same path, no per-reviewer handling. Two sub-agents extend that -contract: - -- **`correctness-reviewer`** — additionally returns `files[]` (a risk level per - file). Use `files[]` for the risk/patterns comment (Step 7) and reviewer routing - (Step 8). -- **`thread-reconciler`** — reads the staged bot threads (with their reply chains) and - the open human-thread lines, and returns `{resolve: [...], keep: [...], skipLines: - [{path, line}, …]}`. Resolve each `thread_id` in `resolve` with the - `resolve-pull-request-review-thread` safe output (yours to do — sub-agents cannot); - never reply to a thread, and for a `keep` thread do not open a duplicate comment in - Step 5. `skipLines` are the lines with an open human thread: do not post a bot - comment on any of them (Step 5). - -**Specialist lenses (`routing.json` `lensesToSpawn`) — structured-schema output.** The -specialist lenses do **not** emit the label-bearing shape. Each returns the **structured -finding schema**: `{"findings": [], "hunts": [{"hunt", "state"}]}`, where every -`` carries `schema_version`, `id`, `lens`, `anchor`, `severity` -(`blocking`/`advisory`), `confidence`, `evidence_trace`, `failure_scenario` (the -concrete failing scenario the claim-validator attacks), `producing_hunt`, -`model_authored_prose`, and optional `suggested_patch` / `pre_merge_obligation`. A -dispatched lens also owns its domain's best-practice skills -for the run: it reads the repo skills index and applies the relevant skill's rules, -carrying the skill's declared severity into the finding's `severity`, while the -`skill-auditor` skips lens-owned skills so no rule is audited twice. - -**Normalize each lens finding into a candidate comment (code-owned label).** A lens -finding has no Conventional-Comment `label` — the label is computed **in code**, never by -the model: `blocking` → `issue (blocking)`, `advisory` → `suggestion (non-blocking)` (a -lens is a correctness/risk lens, so it renders as a plain label, not a `, best-practice` -variant). Take the candidate's `path`/`line` from the finding's `anchor` (a `line` anchor → -`path`+`line`; a `pr` anchor → a top-level review comment with no line), its comment -text from `model_authored_prose` (with `suggested_patch` as the fix block; for a skill -finding carrying `rule_quote`, append the quoted rule to the candidate's `discussion` -as a `> **Rule:** ` blockquote between the prose and the fix block, -matching the shared lib's `renderComment` — the quote is skill-file text copied -verbatim, and it is what lets the author read the actual rule instead of a -paraphrase), and its -`failure_scenario` verbatim (it rides into `claims.json` for the validator). After this -normalization a lens finding is a candidate in the **same** shape as every other -reviewer's, so it flows through the identical scope-filter → `claims.json` → verdict → -inline-comment path with no separate gate. Record each lens's `hunts[]` tri-state -(`ran` / `not-applicable` / `found`) alongside its findings in the lens's `out/.json` -artifact (below); the hunts are provenance/metrics, not comments, so they are not posted. - -**Route out-of-lane observations into the candidate set (code-owned label).** The -`skill-auditor` and every specialist lens may return `out_of_lane_observations[]` -alongside their findings: real concerns their own mandate does not let them report -(for the skill-auditor, a concern that is not a quotable skill-rule violation; for a -lens, a concern outside its domain). Do not discard these. Convert each observation -into a candidate comment in the same label-bearing shape as every other candidate: -`path`/`line` from the observation, `subject` from its `observation` text verbatim, -`failure_scenario` verbatim, and the label **`question (non-blocking)`** — the label -is code-assigned, never model-chosen: an out-of-lane observation is a handoff, not a -vetted finding, so it can never block on its own (and the `claim-validator` never -upgrades severity). Set the candidate's `source` to `" (out-of-lane)"`. From -here each one flows through the identical change-provenance gate → scope filter → -`claims.json` → validation → posting path as every other candidate — do not shortcut -one past validation, and do not drop one because its producer was unsure of its lane -(that uncertainty is exactly why it is handed to the validator). - -Parse each sub-agent's JSON and keep only the compact result. As you parse each one, -also write its raw JSON verbatim to `/tmp/gh-aw/review/out/.json` (create the -`out/` directory if needed) — one file per dispatched sub-agent, named after it, -whatever roster this run dispatched (a lens's file includes both its `findings[]` -and its `hunts[]` tri-state record). These files are uploaded -as a run-scoped artifact at the end (Step 9) so a human can inspect exactly what each -reviewer produced. If a sub-agent's output is missing or unparseable, do **not** try to -reproduce its analysis yourself — you no longer hold its repo-specific config (risk -tiers, the CI-tooling list, the skills index). Skip that dimension for this run: track it -as a skipped dimension and surface the gap with the skipped-dimension note in Step 6 so -the author can see it was not assessed, and write whatever raw text you did get (or a -short `{"error": "..."}` note) to its `out/` file so the gap is visible in the artifact. - -**Gate the candidates by change provenance (code-computed).** A finding must trace -to the change: introduced by it, or a pre-existing defect the diff materially -amplifies (in which case it anchors on the amplifying added/modified line and says -so). Enforce this mechanically against `/tmp/gh-aw/review/provenance.json` (written -by the provenance CLI above), before the scope filter below: - -- A candidate is **change-anchored** when it has no line (a PR-level comment), or - when its `path` has an entry in `provenance.json` and its `line` appears in that - entry's `added` or `removedAdjacent` list (candidates carry RIGHT-side lines; - `removedAdjacent` is what lets a deletion finding, anchored beside the removed - code, pass). Change-anchored candidates continue through the pipeline untouched. -- A RIGHT-side (or side-less) candidate that is not change-anchored but whose - `line` has an entry in - `provenance.json`'s `snap` map (`snap[][]`) is a **near-miss - mis-anchor**; apply the **anchor-snap** fallback. Reviewers sometimes anchor a - finding about a changed line a few lines off, or count unified-diff text lines - instead of file lines and land past the file's actual end; the `snap` map - precomputes exactly which lines that pathology can produce and where each one - belongs. A LEFT-side candidate never snaps (the map is RIGHT-side only). - Rewrite the candidate's `line` to the mapped value, then treat it as - change-anchored from here on (it continues through the pipeline and posts at - the snapped line, keeping its severity). Record every snap in - `/tmp/gh-aw/review/out/snapped.json` (one entry per snapped candidate: the - finding's `id`, `path`, the original line as `from`, the snapped line as `to`) - so the run artifact keeps each rewrite auditable. For a range candidate - (`start_line` set), check each line of the range ascending and use the first - mapped entry; the snapped candidate becomes single-line. The map is the entire - rule: never snap by judgment, and a line with no entry does not snap. -- Every other candidate is a **pre-existing observation**. It does not count - toward the verdict and it does not post to the PR at all — not as its own - comment and not in any collapsed section: remove it from the candidate set now, - before validation. Write the removed set to - `/tmp/gh-aw/review/out/pre-existing.json` (one entry per observation: the - finding's `id`, anchor, and prose) so the run artifact keeps the gate's - set-asides inspectable; the artifact is their only destination. A pre-existing - issue important enough to surface must anchor on a line the diff actually - touches (the "materially amplifies" rule above) — anything that cannot meet - that bar is not this PR's feedback. -- **Fail open.** If `provenance.json` is missing or its `warnings` list is - non-empty (the staged diff could not be parsed), skip this gate entirely (gate - nothing) and surface the gap as a `Note:` line in the review body - (Step 6), so a staging bug degrades to the ungated behavior rather than silently - demoting every finding. - -This gate is positional and mechanical; it never judges content. The -`correctness-reviewer`'s pre-existing-bug rule (flag only on touched lines) keeps -producers aligned with it, and the amplification rule (a pre-existing mechanism may -block only when the diff materially amplifies its consequence, stated in the -finding) is validated by the `claim-validator` in Phase 3. - -**Scope the candidate comments to newly-changed code.** Now filter the cumulative -`findings[]` from every dispatched reviewer and lens against the new-code scope from -Step 1 (`/tmp/gh-aw/review/new-scope.json`). This is what stops the reviewer from -re-commenting on code a previous review already covered: -- If `priorReview` is `false` (first review of this PR), keep everything — nothing has - been reviewed yet. -- Otherwise **drop** any finding whose (`path`, `line`) is not an in-scope - line in `inScope` — that code is unchanged since the last review, so it was already - covered (this holds across force-pushes and rebases because the scope is content-based). - **One exception:** keep a dropped candidate that carries a plain blocking label - (`issue (blocking)` or `todo (blocking)`) — a genuine blocking bug is worth - surfacing even if a change elsewhere introduced it on previously-reviewed lines. - Every other label — nits, suggestions, questions, notes, and all best-practice - findings — is scoped strictly to new code (re-flagging best-practice or style - points on unchanged code is exactly the noise being removed here). - -This filter applies **only** to the inline-comment candidates. `files[]` risk levels, -patterns, and ownership still reflect the whole PR, so Steps 7 and 8 are unaffected. The -findings that survive this filter are the candidate set the rest of Step 3 -acts on. (The existing `thread-reconciler` dedup remains a second layer: even an in-scope -line that duplicates a still-open thread must not open a duplicate comment, Step 5.) - -**Phase 3 — validate the claims (only when there are candidate comments).** The -candidate inline comments are **all** the surviving findings from Phase 2 (after the -scope filter above), from every dispatched reviewer and lens, cumulatively. If the -whole set is empty, skip this phase entirely — there is nothing to -post, so nothing to validate. Otherwise give each candidate a short stable `id` and write -the combined list to `/tmp/gh-aw/review/claims.json` — each entry: `id`, `source` -(the producing reviewer/lens name), `path`, `line`, `label`, `subject`, `discussion`, -`failure_scenario` (the producer's concrete failing scenario, copied verbatim; it is -the specific claim the validator attacks), -any `suggestion`, (for a best-practice finding) its `skill`, and `confidence` (the -finding `confidence` in [0,1] where the producer emitted one — every specialist lens -does; for a label-shape reviewer that carries no confidence, default it to `0.7`, -i.e. above the medium posting bar, so an un-scored real finding is not hidden). This -`confidence` is the field the validator's verification may lower and the posting bar -(Step 5) reads. One more field: when a candidate re-raises a point the author has -**factually disputed** in a staged bot thread (`threads.json`, Phase 2 — the reply -chain shows the author contesting the claim on the merits, not just pushing back on -taste), copy the author's grounds onto the entry as `author_dispute` (a short quote). -Carry every finding's own `label` verbatim — producers own their -labels, and for a specialist lens the label is the code-computed one from the -normalization step, never model-authored. Then -dispatch **`claim-validator`**, which re-checks each claim against the actual code and -returns, per `id`, a three-state `verification` — `confirmed`, `plausible`, or -`refuted` — with optional `corrected` fields. It verifies every claim the same way -whatever its `source`, under symmetric evidence duties: `confirmed` requires citing the -line(s) that make the failing scenario occur, `refuted` requires citing the -guard/handler/definition that prevents it, and anything it can do neither for is -`plausible`. Apply its result before Step 4: - -- **`refuted`** — discard the claim. The validator affirmatively showed it is wrong - (false positive, unsupported, or misleading); it is not posted and does not count - toward the verdict. -- **`plausible`** — retain the claim, **never as blocking**: an unconfirmed claim must - not drive REQUEST_CHANGES. If it carries a blocking label, map the label to the - non-blocking equivalent (`issue (blocking)` → `suggestion (non-blocking)`, - `issue (blocking, best-practice)` → `suggestion (non-blocking, best-practice)`, - `todo (blocking)` → `suggestion (non-blocking)`) and lower its `confidence` to the - validator's returned value; an already-non-blocking claim keeps its label with the - (lower) returned `confidence`. Enforce this mapping yourself even if the validator's - `corrected` object omits it — the gate is mechanical, not advisory. -- **`confirmed`** — retain the claim. If it carries a `corrected` object, overwrite the - claim's `line`, `label`, `subject`, `discussion`, and/or `suggestion` with the - corrected values before posting. This includes severity: the validator may correct an - overstated skill claim by changing its `label` from `issue (blocking, best-practice)` - to `suggestion (non-blocking, best-practice)`. - -**Only a `confirmed` claim may carry a blocking label into Step 4.** The verdict is a -mechanical function of the labels on the posted comments (`computeVerdict`), so -the `plausible` downgrade above automatically removes an unconfirmed claim from the -REQUEST_CHANGES set — recomputing the verdict over the post-validation labels is the -wiring. This gate is what ties REQUEST_CHANGES to re-verified, demonstrable defects; a -blocking-claim escalation beyond it (an adversarial refuter pass over the blocking -survivors) was considered and removed as unearned — if the eval suite's false-block -metric ever regresses, revisit it from this PR's history. - -**An author-disputed claim cannot re-block on the same evidence.** For a claim carrying -`author_dispute`, cap the verification at `plausible` — posted as a **question** engaging -the author's stated grounds, never a re-block — unless the validator returns `confirmed` -with a trace that reaches the **actual usage** (the caller/mount/production path, not just -the nearest definition) and speaks to those grounds. Production showed why the bar is -usage-depth: a wrong a11y re-block survived two checks that each stopped one parent short -of where the disputed element actually lived. - -The findings that survive this phase — with any corrections applied — -are the set Step 4 (verdict) and Step 5 (comments) act on. If `claim-validator`'s -output is missing or unparseable, do **not** drop the comments: post the unvalidated -claims anyway, and surface the gap as a skipped dimension (`claim validation`) with the -note in Step 6, so the author knows they were not double-checked this run. - -**Run out of budget gracefully: always land the review.** Two hard ceilings kill a -run that overruns: the per-run AI-credits cap (the frontmatter's -`max-ai-credits`; the daily cap is disabled separately) and the job's -`timeout-minutes`. A run that dies at a hard ceiling costs everything and -delivers nothing, so a hard ceiling must never be what stops you: treat the -router's soft targets (`runBudget`, Step 3) as the point to start landing. The -router clamps those targets to the effective credit cap (the -`REVIEW_MAX_AI_CREDITS` mirror of `max-ai-credits`) with a landing reserve -held back: the clamped `maxUsd` is 75% of the cap, not the cap itself, because -spend is unobservable mid-run and work already in flight bills after your last -checkpoint, so a run that sheds exactly at the cap still dies at it. When -`runBudget.capClamped` is true the cap is tighter than the tier's normal -budget — dispatch conservatively from the start and expect to shed. Treat -`maxUsd` as the landing target, never as money you may finish spending. Nothing reports exact credits consumed back to you -mid-run, so watch the signals you can observe, as spend proxies: - -- **Elapsed wall-clock** vs `runBudget.maxWallClockMinutes`: diff `date +%s` - against the run start you recorded in Step 1 at each later checkpoint. This is - the sharpest proxy, and the job-timeout ceiling it guards is just as fatal as - the credits cap. -- **Dispatch count** vs `runBudget.maxReviewerInvocations`: finding-producing - reviewers and lenses already dispatched plus still pending. Only those count. - `pattern-triage`, `thread-reconciler`, and the `claim-validator` are pipeline - steps, not reviewers; they never consume a slot of this cap. -- **Estimated credits** vs `runBudget.maxUsd × 100`: every finished sub-agent - reports its tokens in-band (the `subagent_tokens` line of its result's - `` block). Estimated run credits ≈ the sum of `subagent_tokens` over - completed sub-agents ÷ 5,000. (Derivation: measured runs average roughly - 9,000 summed tokens per credit, and sub-agent tokens are only part of total - spend — your own orchestration turns are unmetered — so ÷5,000 folds in the - safety margin. An estimate, not an invoice: use it to shed, never to justify - spending more.) -- **Run-wide investigation usage** vs `runBudget.maxTotalToolCalls`: one line per - authorised call in `/tmp/gh-aw/review/investigation-journal.log` (`wc -l`). -- **Trajectory**: an unusually large diff, many sub-agents still pending, many - turns already spent. - -Two checkpoints are mandatory, not judgment calls: recompute every proxy (1) -immediately after the last finder returns, BEFORE starting Phase 3 validation -— validation is itself model work, and dying there wastes findings already in -hand — and (2) before dispatching each additional wave of reviewers. - -When any proxy passes roughly three-quarters of its soft target (or the trajectory -is clearly expensive), stop starting new work and shed remaining work in this -order: - -1. Skip not-yet-dispatched opt-in reviewers and specialist lenses in value - order, lowest value first; each becomes a skipped dimension (Step 6 note). - The ranking, from first-shed to last-shed: `conventions`, then - `first-principles`, then `holistic`, then `completeness` and - `test-adequacy`, and only then any path-triggered specialist lens from - `lensesToSpawn`. A matched lens is the most targeted signal in the run (the - router chose it for the specific files this PR touches), so it outranks - every generic dimension; shedding `security-auth` on an auth-path diff to - afford `conventions` is exactly backwards. This same ranking, read from the - other end (defaults, lenses, targeted opt-ins, generic opt-ins), is the - dispatch order when the invocation cap cannot fit the roster (Phase 2). - The interior order is a first-cut editorial ranking; replace it with - measured per-dimension must-catch contribution once the eval corpus - yields that data. -2. Skip the risks/patterns comment (Step 7) if it has not happened yet. - Reviewer requests (Step 8) are **never** shed: pulling a human in matters - most on exactly the run whose own coverage is partial. -3. Last, and never at the soft targets alone: the `claim-validator`. It is the - false-positive gate, and its cost scales with the candidate count (which you - can already see when deciding), not with the diff, so validating a small - candidate set costs less than one reviewer dispatch. Shed it only when a - hard ceiling is genuinely close (elapsed wall clock past three-quarters of - the job's `timeout-minutes`, or an equally direct signal that the credits - cap is near); at a mere soft-target breach, dispatch it anyway and shed - elsewhere. When it is shed, post the unvalidated candidates under the - missing-validator rule (Phase 3), using the planned-shed wording of the - skipped-dimension note (Step 6). - -Then go straight to Steps 4-6: compute the verdict from the findings already -validated, post the surviving comments, and submit the review with one -skipped-dimension note per dimension you shed. A partial review that posts always -beats a complete review that never lands. - -## Step 4: Determine the Review Verdict - -Decide the verdict BEFORE writing any comments, because it affects which comments you -post. The verdict is a **mechanical function of the labels on the comments you will -actually post** — every finding that survived validation (Step 3 Phase 3), from -every dispatched reviewer and lens, after any corrections, after the -change-provenance gate, after the -newly-changed-code scope filter, and after -dropping candidates on open human-thread lines (Step 5). A claim the validator -dropped or downgraded to non-blocking, or that the provenance gate, scope filter, or -human-thread filter removed, -is not in that set and cannot affect the verdict. Because the verdict follows only the -posted labels, an advisory-only reviewer (one whose definition permits it only -non-blocking labels) can never drive REQUEST_CHANGES, and an `advisory`-severity -lens finding is code-mapped to a non-blocking label — counting labels already -handles them; there is no separate advisory carve-out to maintain. - -**Blocking labels:** `issue (blocking)`, `issue (blocking, best-practice)`, and -`todo (blocking)`. Every other label is non-blocking: `suggestion (non-blocking)`, -`suggestion (non-blocking, best-practice)`, `nitpick (non-blocking)`, -`question (non-blocking)`, `thought (non-blocking)`, and `note (non-blocking)`. - -**The rule:** -- **REQUEST_CHANGES** if and only if at least one comment you are going to post carries a - blocking label. -- **APPROVE** otherwise — including when the posted set contains only non-blocking - comments. **Never REQUEST_CHANGES when every comment you are posting is non-blocking.** - -There is no separate judgment: if a finding is a real defect it should carry a blocking -label (see below), but the verdict follows the labels on the actual posted comments, not -a category call. Count the blocking labels in your final comment set; zero blocking -labels means APPROVE. - -**The re-review flip rule (reduced depths only).** One addition to the rule above -when `rereview-plan.json` (Step 3) says `depth` is `flip-gated` or `fast` and the -latest fingerprint stamp's `verdict` was `REQUEST_CHANGES`: read the stamp, not the -review state, since branch protection may have dismissed that review. A reduced-depth -run reviews little or nothing new, so its APPROVE would mean "the prior objections -are resolved"; it may flip to APPROVE only when the code-rendered accountability -result (`/tmp/gh-aw/review/rereview.json`, Step 6) has `keptBlockingCount: 0`, that -is, the reconciler resolved every blocking thread. If `keptBlockingCount` is greater -than zero, the verdict is REQUEST_CHANGES even though this run posted no new blocking -comment; the accountability section lists the surviving threads, so the author sees -exactly what still blocks. In `flip-gated` depth the dispatched correctness pass adds -the second half of the gate mechanically: any validated blocking finding it produced -posts and blocks under the rule above, so a fresh defect vetoes the flip instead of -being discarded. This rule never applies to `full` or `scoped` depth, where the whole -roster re-reviews and the plain rule above stands alone. - -### What should carry a blocking label - -**Blocking requires a concrete failing scenario.** A finding may carry a blocking -label (`issue (blocking)` / `issue (blocking, best-practice)` / `todo (blocking)`) **only -when the reviewer can name a concrete failing scenario** — specific inputs, state, or -conditions under which the code produces a wrong or unsafe outcome (a bad value returned, -data corrupted, an authorization skipped, a request that errors, a user-visible break). -"This looks risky", "this could be a problem", or a style/architecture preference with no -demonstrable failure is **not** blocking — it is at most `advisory`. The scenario is the -finding's `failure_scenario` field (every producer emits one on every finding) and must be -supported by the finding's `evidence_trace`; the `claim-validator` (Step 3 Phase 3) -downgrades any blocking claim whose stated scenario it cannot confirm from the cited -evidence. This gate is what keeps REQUEST_CHANGES tied to real, demonstrable defects. - -Label a finding blocking (which is what then drives REQUEST_CHANGES) when it is: - -**Correctness defects** (that CI would NOT catch): -- Logic errors that pass type checks (wrong condition, off-by-one, etc.) -- Security vulnerabilities (XSS, secrets in code) -- Race conditions or incorrect async handling -- Incorrect business logic -- Data-layer correctness that the type checker won't catch (e.g. a cache that - breaks because a required identifier field is missing from a query) -- Public API type unsafety that downstream consumers would hit at runtime - -**Best practice violations** — only when labeled `issue (blocking, best-practice)`: -- A blocking best-practice finding drives - the verdict. An advisory one is labeled - `suggestion (non-blocking, best-practice)` and does **not** block — it rides along - with an APPROVE. The producer sets the label from the skill file's declared - severity, or its impact judgment when the skill doesn't declare one. -- A **specialist lens** owns its domain's skills and carries their severity in the - finding's `severity`, but a lens is a correctness/risk lens, so the normalization - step maps it to a **plain** label: `blocking` → `issue (blocking)` (drives the - verdict), `advisory` → `suggestion (non-blocking)`. - -Do NOT label these blocking (CI catches them), and do not let them drive the verdict: -- Type errors, lint violations, test failures -- Import ordering, formatting issues -- Missing semicolons, unused variables - -If none of the posted comments qualifies for a blocking label, the verdict is APPROVE — -you can still approve with non-blocking inline comments. - -## Step 5: Leave Per-Line Review Comments - -All review comments MUST use Conventional Comments format -(https://conventionalcomments.org/). Every comment starts with a label that -signals intent and urgency. - -**Be concise.** Keep every comment as short as it can be while staying clear — -ideally one or two sentences. State the problem and, when useful, the fix; do not -restate the code, recap the diff, add preambles or pleasantries, or over-explain. A -terse, specific comment is far more likely to be read and acted on than a verbose one. - -### Conventional Comments format - + It runs triage, the reviewer fan-out (roster, budget cap, and planned + sheds computed from `routing.json`, every dispatch staged to + `out/.json`), the provenance gate, the scope filter, cross-source + dedup, open-thread suppression (a candidate that describes a defect an + open bot thread already tracks is not re-validated or re-posted; a + suppressed blocking candidate still floors the verdict when the matched + thread's opener is itself blocking), and claim + validation, and writes `/tmp/gh-aw/review/dispatch-result.json`. +3.
