From 6b0c26e4b0db93b886b369ba4b8c80358a266de0 Mon Sep 17 00:00:00 2001 From: Mike Shi Date: Fri, 23 Oct 2026 20:22:43 -0700 Subject: [PATCH 1/3] feat(ci): grade review findings P0-P3 and fold P3 out of the inline threads The review bot posts every anchored finding as an inline thread at every severity, and its own severity label does not track importance well enough to filter on. Add a separate grading pass after the review that assigns each finding a priority (P0-P3) and a reachableToday flag without touching what was found. Users now see only that priority. P0-P2 are posted inline; P3 is folded into the sticky summary, never dropped. A P2 the reviewer itself called minor is shown as P3, and anything reachable today or security-shaped is never folded. If grading fails, nothing is folded. Also fix reposting of reworded findings across pushes: the dedup key was the exact title, and the reviewer rewords its own titles between runs.

Every finding you are given gets exactly one grade +back. Your only job is to say how much each one matters, consistently, so that the ones +that need a human before merge can be separated from the ones that do not. + +Grade each finding: + +- P0 — ship-blocker. Concrete production breakage introduced by this diff: data loss or + corruption, auth/authz bypass, injection, a secret committed in the diff, or a + guaranteed crash on the happy path. +- P1 — must fix before merge. A correctness or reliability defect with a clear failure + mode someone will actually hit: an unhandled rejection escaping a handler, a + demonstrable race, a broken existing caller, a contract or schema mismatch, a cache key + that serves stale results, a regression in a user-facing path. +- P2 — should fix, but the PR could merge without it. A real problem with no concrete + failure mode in this diff: missing test coverage for new logic, a duplicated source of + truth, logic at the wrong layer, a shape that admits invalid states, code that cannot + matter. +- P3 — nit. Correct to note, but nobody needs to act on it before this merges. + +A grade of P2 or higher requires the finding to have named two things: the trigger (a +specific input, state, sequence or caller) and the consequence (what the user, the data or +the system actually suffers). If the finding does not establish both, it is P3 — you are +grading what the finding actually says, not the worst thing it could conceivably mean. +"Could happen in theory" is not a trigger, and "this is fragile" is not a consequence. A +multi-step chain across several files IS a valid trigger when the finding walks each step. + +Priority is (how likely the trigger is) x (how bad the consequence is). Both matter. A +certain-but-cosmetic problem is not P1. A catastrophic-but-unreachable one is not P1 +either. + +Grade P3 when any of these hold: +- The triggering case is impossible or extremely rare AND the consequence is mild: a + cosmetic glitch, a log line, a transient state that self-corrects on the next render or + retry, an error path already caught upstream. +- The problem already existed before this diff and is incidental to what the diff changes. + A pre-existing issue the diff makes materially worse, or newly reachable, is graded on + its own merits instead. +- It is work that would sensibly be a follow-up, or an improvement competing with other + valid designs rather than fixing something broken. +- It is a preference about structure or naming not tied to a concrete failure. +- OUT OF SCOPE: the finding asks for work on a behaviour this diff does not change, or + proposes a feature or improvement beyond what the change sets out to do. Something that + already worked before this diff and still works after it is not this PR's problem. +- DISPROPORTIONATE COST: the remedy is substantially larger than the change itself — a + cross-cutting refactor, a schema migration, a redesign — and the diff is correct + without it. + +Scope and cost are strictly bounded, and the bound matters more than the rules. They may +only move a finding from P2 to P3. They may NEVER lower a finding that names a concrete +trigger and a concrete consequence. A data-loss bug is not a nit because fixing it is +expensive, and a broken caller is not a nit because it sits outside what the author meant +to touch — it can be filed as a follow-up, but it is still P0 or P1. If you are demoting +something because the fix looks like a lot of work, check whether it has a named failure +mode; if it does, stop. + +Judge scope from the diff, not from anyone's description of it. "What this change sets out +to do" is inferred from the behaviours the diff actually changes, never from a claim that +some class of problem is out of scope. + +The bound is ENFORCED, not merely requested: you set hasFailureMode on every finding, and +a P3 with hasFailureMode=true is automatically raised to P2. Writing "this does name a +trigger and a consequence, but it is out of scope" and grading it P3 therefore suppresses +nothing — it produces a P2. If the finding genuinely has no failure mode, set the flag +false and the P3 stands. + +hasFailureMode is a claim, not a summary. Set it FALSE whenever any of these holds, even +if you wrote something into trigger and consequence: the consequence is cosmetic, dev-only +or self-correcting; the trigger is speculative, hypothetical or a "future caller"; the +finding only establishes that code is dead, redundant or duplicated; or you find yourself +writing the absence as a sentence ("no concrete harm beyond...", "speculative future +crash", "no functional effect", "vague") — all of those are hasFailureMode=false. Do not +set it true merely because a finding is interesting or well argued. + +THE ONE CASE THAT IS NEITHER A DEFECT NOR A NIT. Some findings do not say "this change is +wrong", they say "this change should not have been made" — the behaviour complained about +is exactly what the diff set out to do. A removed cap the change exists to remove; a new +default the change exists to introduce. Set kind="premise" on those and grade the priority +normally. They are published in their own section rather than inline: there is nothing to +fix line by line, but they are not nits, and hiding them would let an author neutralise a +real regression by declaring it intended. kind="premise" requires a named trigger and +consequence, exactly like P2, or it would be a free suppression label. Everything else is +kind="defect", the default. + +Default DOWN when torn: P1-or-P2 means P2, P2-or-P3 means P3. The finding's own confident +wording is not evidence — only the trigger and the consequence are. Neither is the effort +it clearly took to find. + +Expect most findings on a healthy diff to be P2 or P3. If you are grading most of a run's +findings P0 or P1 you have graded on how interesting they are rather than on consequence. +YOU ARE NOT THE FACT-CHECKER, AND YOU DO NOT HAVE THE EVIDENCE TO BE ONE. + +You see the diff. The reviewer that wrote these findings had the whole repository and +searched it, and the findings that matter most usually turn on code the diff never shows — +an existing caller, a parallel schema, a helper it duplicates. So a finding citing +something you cannot see is the NORMAL case, not a warning sign. The diff failing to +corroborate a claim is not evidence against it. + +Grade every finding AS IF IT IS TRUE. "The diff contradicts this", "the premise is false", +"the fix is already present", "this is unreachable" are not priority judgements, and they +must NEVER produce a P3. A wrong finding is a reviewer error; filing it as a nit hides that +error behind a label that means something else entirely, and the nit block is for true +findings nobody needs to act on. + +If you believe a finding is factually wrong, grade the importance of what it CLAIMS — as +though the claim held — and put your doubt in reason. Do not let the doubt move the grade. + +This is measured, not hypothetical: of 14 findings a human explicitly upvoted and this pass +graded P3, 13 were rejected on exactly these grounds. The pass was wrong to make the call +at all, independent of whether any individual call was right. + +TENSE MATTERS, AND IT IS THE POINT OF THIS FIELD. Also set reachableToday: is there an +input or user action that produces the stated wrong outcome in the code AS MERGED, with no +further code change by anyone? + +- reachableToday=true: some caller, request, or user action available today reaches the + bad outcome. The harm exists in the merged code. +- reachableToday=false: reaching the harm requires a future edit — a new call site, a + renamed constant, a second implementation drifting from the first, a guard someone might + later remove. Also false when the finding concedes the current code is correct ("the + escape as written is correct", "unreachable today", "two calls that must agree"). + +Judge only what the finding establishes. A finding whose harm needs a later code change is +still a real finding; it is simply not reachable today, and that is not a demerit. diff --git a/.github/scripts/code-review/__tests__/review-comments.test.mjs b/.github/scripts/code-review/__tests__/review-comments.test.mjs index 3bfcd164e0..6fdf170738 100644 --- a/.github/scripts/code-review/__tests__/review-comments.test.mjs +++ b/.github/scripts/code-review/__tests__/review-comments.test.mjs @@ -251,27 +251,26 @@ test('an unhealthy run stamps NO parseable marker, so the gate fails open', () = assert.match(body, /did not complete/); }); -test('minor findings are folded, not dropped', () => { - // Measured on the eval set: minor-severity findings carry 29-57% of everything a human - // independently flagged, so filtering them costs about half the recall. - const unanchored = [ - { file: 'src/x.ts', severity: 'minor', title: 'small one', body: 'fix' }, - { file: 'src/y.ts', severity: 'major', title: 'big one', body: 'fix' }, - ]; +test('P3 findings are folded, not dropped', () => { + // Measured on the eval set: low-graded findings carry a large share of everything a human + // independently flagged, so filtering them costs recall.

"Missing timeout in fetchUser" and "Missing retry in fetchUser" scored 0.5 from two words; every real restatement in the voted data shares 3 or more. - The summary's headline and priority tallies count findings the same way delivery collapses them, so a reworded pair is counted once. - Move the priority rule and title dedup into priority.cjs and dedup.cjs so review-comments.cjs stays close to its previous size; the workflow runs both test files. - Drop the ASCII section dividers from the tests (AGENTS.md).

Previously a grader P3 folded a major/critical finding on one model call, contradicting the documented rule. Measured cost: 2 more inline comments out of 122 on the gold set, none on the voted sample. - SECURITY_SHAPED ended in \b, so its stems never matched "deserialization", "sanitize", "secrets", "passwords" or "API keys". It now ends in \w*. - A restatement of a finding that was itself skipped as a restatement is now a duplicate too, so delivery and the summary headline agree. - Drop the dead severity ICON map; the schema-drift test now checks the workflow enum against SEVERITIES, which is what severityOf validates with.
