Greptile P1 on Runfusion#3664 is correct against this exact content: the census called all 218 error-line cases "confirmed regressions", but the families are keyed mechanically on the first error line, which shows THAT a case fails, not WHY. The runtime-Error family proves it - it pools a 30s timeout, a 5s timeout and an ENOENT for a missing packages/cli/src/commands/research.ts. None of those establishes an old call contract or a stale harness double, which is the definition the fixed-here table used. Split the claim: 17 verified here, 201 real failures with unverified cause, 15 unresolved. 17+201+15=233. No test or product change: prose only in the census doc.

232-259: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExercise the production resolver in the periodic-sweep test.
This test replaces
resolveMergeGateBlockerwithundefined, so it only checks the later lane-aware blocker call. It does not cover the resolver path that callsgetTaskMergeBlocker(task)withoutreviewColumns. That path can apply the literalin-reviewlane and reject a renamedsignofftask beforecanMergeTaskruns.The full PR diff does not change the production resolver or core blocker. Update this test after the pre-existing resolver fix, or add a neighboring integration test that exercises the complete sweep and asserts admission for the renamed lane.

What this delivers
Main's non-blocking Full Suite lane is red again, and red now means something. This PR names and classifies every failing suite behind the streak so an operator can tell a flake from a real regression instead of guessing. Confirmed flakes are quarantined under the project's deletion ratchet; real regressions are routed to focused follow-up cards with exact reproduction steps.
Supersedes #3663, which was closed unmerged with 9 open review findings. All substantive findings are addressed here — see Review findings addressed below.
The streak
Non-blocking Full Suite on
mainis red on 6 consecutive push runs (2026-09-23 02:01Z–04:38Z, Runfusion/Fusion). Gate-tier jobs (Lint, Typecheck, Build, Gate) stay green; failures cluster in the 4 deterministic vitest shards plus the Pipeline smoke tier.Evidence: 1762 runs, 233 named cases across 117 distinct test files, 0 flakes.
FAILlinesTest shard 1/4(@fusion/engine1/2)Test shard 2/4(@fusion/engine2/2)Test shard 3/4(@runfusion/fusionCLI)Test shard 4/4(@fusion/core2/2)The Pipeline smoke tier fails separately: the watchdog kills
engine-pipeline-smokeat its 175 000 ms budget. The PostgreSQL service log in the same job showsFATAL: password authentication failed for user "runner"/Role "runner" does not exist.Classification: 0 flakes among the 218 classified cases; 15 unresolved
Checked before treating anything as a regression:
scripts/lib/test-quarantine.jsononmainholds exactly one entry —packages/desktop/src/__tests__/native.test.ts(quarantined 2026-09-24, second-sighting rule). The ledger is not empty. That file is not among the 117 census files, so no census case is already quarantined; the conclusion rests on the file being absent from the inventory, not on an empty ledger.docs/solutions/test-failures/suite-only-flakes-observed-register.mdissrc/__tests__/plugin-runner.test.ts, and that record (entry 3) is Closed 2026-08-17 by FN-9141 — rescued (fixture defect); its ledger row and exclude were removed. It is not an active flake.engine-coreallow-list rather than quarantined. No census case is in that allow-list, so no eviction applies.Verdict: no first-sighting flake record and no quarantine entry is warranted.
Of the 233 named cases, 218 carry a supported classification and are real regressions — a test that asserts a call shape the product has since changed, or a harness double that no longer satisfies the product's collaborators. The remaining 15 (
assertion-no-error-line) are unresolved, not regressions: the shard log carries no error text for them, so naming a cause would be a guess. FUSI-034 owns reproducing them.Regressions fixed here
