From 095a3967c4cfe05650ea150dc2e29cf6d5f56c85 Mon Sep 17 00:00:00 2001 From: dtoro Date: Tue, 7 Jul 2026 15:19:25 +0200 Subject: [PATCH] =?UTF-8?q?phase=203:=20control=20loop=20=E2=80=94=20sched?= =?UTF-8?q?uler,=20actuator,=20learning,=20notifier,=20policy,=20API=20end?= =?UTF-8?q?points?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented the full OODA control loop: Scheduler: - Check_defs runner with bounded worker pool (errgroup) - Signal dedup via partial unique index (UpsertSignal) - Recovery auto-resolves open signals - Metrics writing (InsertMetricSample) and entity_status updates - Housekeeping (idempotency-key prune) - Graceful shutdown via ctx cancellation Actuator: - Auto-act signal consumer with FOR UPDATE SKIP LOCKED pattern - Per-target serialization with pg_advisory_xact_lock - Circuit breaker per target host (N consecutive failures → open) - Autonomy kill-switch (global.auto_act, never_auto_act.) - Execution record lifecycle (proposed → running → completed) Learning engine: - Hourly feedback extraction past watermark - Wilson score confidence lower bound (conservative for small N) - Pattern status: hypothesized → validated (N≥5, confidence ≥0.7) - Anomaly quarantine for burst feedback - Cap confidence by sample_size/5 (nothing confident before 5 samples) Notifier: - Approval token generation (HMAC single-use, hashed at rest) - Pending approval expiry detection - DB rendezvous pattern (no service-to-service RPC) Policy classifier: - Risk class resolution from policy tables - Autonomy checks (global + per-entity kill-switch) - Blast radius computation - Classification routes: auto-act / escalate / hold API endpoints (31 endpoints implemented): - Checks: ListChecks, CreateCheck, PatchCheck - Classifications: ListClassifications - Executions: ListExecutions, GetExecution, RequestExecution, CancelExecution - Approvals: ListApprovals, DecideApproval - Patterns: ListPatterns, PatchPattern - Skills: ListSkills, PatchSkill, ListSkillVersions - Policy: ListApprovalRules, CreateApprovalRule, PatchApprovalRule, GetAutonomySettings, PatchAutonomySettings, ListRiskClasses - Relationships: CreateRelationship, EndRelationship - Entity types: CreateEntityType, PatchEntityType - Metrics: QueryMetrics, GetTrends - Knowledge: SearchKnowledge, GetEntityKnowledge (stubs) - Agent activity: QueryAgentActivity (stub) Infrastructure: -
