From 5ebb0f39f06a974dc6b6d412ef306b834386e586 Mon Sep 17 00:00:00 2001 From: ruv Date: Tue, 7 Jul 2026 00:06:32 -0400 Subject: [PATCH] =?UTF-8?q?feat(workspace-probe):=20@metaharness/workspace?= =?UTF-8?q?-probe=20=E2=80=94=20eval=20+=20Darwin-Mode=20bridge=20for=20wo?= =?UTF-8?q?rkspace-lens=20(ADR-239)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A thin, pure companion to @metaharness/workspace-lens (ADR-238) that turns Jacobian-Lens interpretability receipts into evaluation signal: - workspaceProbeScore(receipts, {driftThreshold}) → { n, score=cleanFraction, meanDrift, flagRate, criticalRate } — a flywheel-consumable `workspace_probe` surface: the fraction of decisions whose workspace was clean (no critical trigger AND drift below threshold). Empty set → 0 (nothing witnessed → no credit). - gradeMutationByWorkspace(baseline, mutant, opts) → { keep, reasons, baseline, mutant } — Darwin-Mode mutation evidence: a VETO that rejects a mutation which raises the critical-trigger rate, destabilizes the workspace (mean drift up beyond tolerance), or drops the clean fraction — even if final answers improved ("final answer up, workspace grip down" = structurally brittle). Pairs with the gold/answer gate (keep only if BOTH pass); never weakens it. meetsPromotionRule untouched. Depends only on the workspace-lens types; deterministic; $0. Logic was developed + validated in isolation against the published @metaharness/workspace-lens@0.1.0, then re-homed with a local workspace dep. 9 synthetic tests; tsc clean; healthcheck 8/8. Wired into build-ordered phase-2 (after workspace-lens) + the version-coherence allowlist; ADR-239. (The lockfile also gains the workspace-lens entry that #129 did not add.)
