With >=2 models the swarm now posts ONE consensus comment instead of a
per-model comment each. Every model writes its structured findings to a shared
dir (GADFLY_FINDINGS_OUT); after the swarm finishes, a consolidation pass
(the binary in GADFLY_CONSOLIDATE_DIR mode) clusters findings by location
(±3 lines), counts how many models independently flagged each, escalates to the
highest reported severity, and renders an agreement-ranked table — cross-model
agreement being the strongest real-vs-false-positive signal we have.
- consensus.go: modelFindings artifact, collectFindings (shared with emit),
writeFindingsOut, runConsolidate, clustering + renderConsensus. Lone
low-severity findings fold away; a lone critical still surfaces; each model's
full review is preserved folded inside the one comment.
- main.go: GADFLY_CONSOLIDATE_DIR dispatches to consolidation; writeFindingsOut
after a normal review.
- emit.go: reuse collectFindings (one definition of "what a finding is").
- run.sh: when GADFLY_CONSOLIDATE=1, write findings + skip the per-model comment
(live progress still on the status board).
- entrypoint.sh: auto-enable for >=2 models; run the consolidator after the
barrier and upsert ONE consensus comment; FALL BACK to per-model comments if
consolidation yields nothing (advisory invariant: never lose output).
- README + reusable workflow (`consolidate` input) + entrypoint docs updated.
Tests: clustering/agreement/tolerance, severity escalation, nit folding, lone
critical, write→consolidate round-trip, empty-dir error. gofmt/vet clean.
