From cb2ab66d4fa2520dd362f17a45f716b272386e86 Mon Sep 17 00:00:00 2001 From: Mikael Hugo Date: Sat, 2 May 2026 12:57:48 +0200 Subject: [PATCH] =?UTF-8?q?feat(sf):=20UOK=20production=20hardening=20?= =?UTF-8?q?=E2=80=94=20diff=20capture,=20exit=20symmetry,=20commit-gate?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three production gaps Codex's adversarial review flagged are now closed: 1. Real legacy-vs-UOK parity diff (per turn, per plane): - parity-diff-capture.ts captures plan / graph / model-policy / audit-envelope / gitops decisions for both paths and emits ParityDiffEvent records to .sf/runtime/uok-parity.jsonl. - parity-report.ts aggregates divergencesByPlane, populates criticalMismatches with real divergence summaries, and tracks enterEvents / exitEvents / missingExitEvents for symmetry. 2. Exit-event symmetry: - sessionId / turnId now flow through enter+exit parity events. - writeParityHeartbeat lets kernel/loop-adapter emit best-effort diagnostics on plane failure paths so missing-exit gaps shrink. 3. Commit-gating on divergence or missing-exit: - resolveParitySafeGitAction (in uok/gitops.ts) reads the parity report and downgrades turn_action to status-only when divergence count > 0 or missing-exit count > 0 — UOK can no longer commit on top of unverified state. - auto-post-unit.ts now resolves a configuredTurnAction from UOK flags then asks the parity gate for the safe action; the gate's decision is what flows to the actual git op. - new test: tests/uok-gitops-commit-gate.test.ts. - existing gitops-wiring assertion updated for the renamed configuredTurnAction (semantic preserved). Tests: 53/53 UOK pass.
