Lift suite run #004 left two unresolved tail issues:
- Q6 ("Forklift loader") ↔ Q7 ("Hazmat warehouse, cold storage")
swap recordings as warm top-1 because their embeddings are within
0.20 cosine of each other. Distance gate can't tell them apart.
- Q9 + Q15 lose paraphrase recovery when qwen2.5 rephrases past the
0.20 threshold. Distance says "drift too far"; sometimes the drift
is real (skip), sometimes the paraphrase is still on-domain (don't
want to skip).
Multi-coord run #008's judge re-rating proved the LLM can
distinguish: Q3 crane case landed at distance 0.23 (looks tight)
but rating 1 (irrelevant). The judge sees domain mismatch the
embedder doesn't.
This commit lifts that pattern into the matrix substrate. Shape B
inject now optionally routes every candidate through a judge gate
before the rank insert lands. Distance + judge BOTH have to approve.
internal/matrix/playbook.go:
- InjectPlaybookMisses signature gains a query string + an
optional InjectGate. nil gate preserves pre-judge-gating
behavior (current tests already pass with nil).
- New InjectGate interface + InjectGateFunc adapter for tests
and non-LLM callers.
- Per-candidate gate.Approve(query, hit) call inserted between
the dedup and the inject. Rejected candidates skip silently;
injected count reflects post-gate decision.
internal/matrix/judge.go (new, ~140 lines):
- LLMJudgeGate calls an Ollama-shape /api/chat endpoint with the
same 1-5 staffing-rubric prompt that worked in multi_coord
run #008. fail-closed on HTTP/JSON errors (don't inject if
judge can't speak — better miss than wrong-domain).
- NewLLMJudgeGate returns nil when URL or Model is empty,
matching InjectGate's nil-means-no-judge semantics.
internal/matrix/retrieve.go:
- SearchRequest gains JudgeURL, JudgeModel, JudgeMinRating
fields. Run() builds an LLMJudgeGate when set; passes nil
otherwise. Backward compatible — existing callers see no
behavior change.
Tests:
- TestInjectPlaybookMisses_GateRejectsCandidate (rejectAll → 0
injected, even with tight distance)
- TestInjectPlaybookMisses_GateApprovesCandidate (approveAll →
same as nil-gate behavior)
- TestInjectPlaybookMisses_GateSeesCorrectQuery (gate receives
CURRENT query + RECORDED query separately so it can score
the (current, candidate) pair)
- All 5 existing inject tests updated to new signature
go test ./internal/matrix → all 8 inject tests pass.
go test ./internal/matrix ./internal/shared ./cmd/{matrixd,
queryd,pathwayd,observerd} → all green.
STATE_OF_PLAY:
- OPEN item #1 (judge-gated injection) closed.
- DO NOT RELITIGATE adds the substrate-level judge-gate lock.
- OPEN list now 5 rows (was 6).
