Investigated A8 (pin @metaharness/darwin + retire the type-mirror):
- VERIFIED: AQE's DarwinScoreCard mirror is byte-identical to upstream ScoreCard
from @metaharness/darwin@0.2.1 THROUGH the published 0.7.0 (no drift, 5 minors).
- HELD the dep-swap deliberately: upstream is fast-moving pre-1.0 with napi/wasm
transitive deps; adding it changes every user's install + lockfile and can't be
verified locally (host-shared-node_modules breaks native rebuilds) — negative-EV
vs 74 stable, zero-coupling mirror lines.
- SHIPPED the version-contract half: pinned provenance (0.2.1–0.7.0) + a drift-
guard test (darwin-version-contract.test.ts) that fails CI on any field-set
divergence. 17 darwin tests green; tsc clean.
Swap only after upstream stabilizes (≥1.0) + a CI-verified install impact; needs OK.

Cross-pollination with Ruv's MetaHarness Darwin Mode: evolve the harness
around a frozen cheap local model, graded by AQE's objective QE metrics.
- docs/metaharness/06-...: GOAP action lane + ADR-style decision (→ ADR-111)
- A1: real mcp-scan snapshot of AQE's MCP surface (.harness/mcp-policy.json
mirror) → 2 HIGH (default-deny OFF, shell granted), 6 MED, 2 LOW
- D0: local-mutator spike benchmark on host M5 Ollama (qwen3:8b/30b > gemma4
as mutator; mock+LLM gives no fitness signal — documented)
- D1: src/integrations/darwin — QE→Darwin ScoreCard adapter folding ADR-104
arena metrics (kill-rate/coverage/cost) + ADR-072 promotion-gate mirror
(15/15 tests green, strict-tsc clean, zero coupling to @metaharness/darwin)
- D6: prototyped + proved a `customScore` hook in Darwin's evolve loop
(patch in prototype/, Ruv's tree left pristine). QE-native scoring now
DIFFERENTIATES variants: winner +0.1230 over baseline, 3 promotions
(vs flat 0.765 from the mock substrate)
Two upstream PRs to ruvnet/agent-harness-generator are staged but unsent:
the customScore hook + --ruvllm-timeout/max-tokens CLI flags.

Six user-reported MCP fixes (see CHANGELOG and docs/releases/v3.9.30.md):
- #467 __dirname ESM polyfill across 7 source files
- #469 real all-MiniLM-L6-v2 embeddings (was random-vector mock)
- #470 NaN guard in coherence_collapse risk categorization
- #472 default test phases when MCP wrapper omits the list
- #473 wire SessionOperationCache into MCP tools/call dispatch
- #474 validate language and auto-derive framework in test_generate
Also fixes a pre-existing field-name typo in
tests/integrations/agentic-flow/e2e-integration.test.ts (.similarity →
.score) that was vacuously passing because the previous mock embedding
generator rarely cleared the threshold to exercise the assertion.

125 test files had beforeEach/beforeAll but no afterEach/afterAll,
leaking state between tests and causing order-dependent failures.
Added cleanup to 104 files (skipped 4 archived, 16 import-only):
- 2 critical DB handle leaks (witness-chain): added db.close()
- 7 high-risk service files: added vi.restoreAllMocks()
- 7 beforeAll files: added matching afterAll
- 88 medium/low risk: added afterEach with appropriate cleanup
