c96c795126 test: add unit tests for 6 previously-untested packages (R7)
Added pure unit tests for all packages that had 0% coverage. Where pure
logic was entangled with DB calls, extracted testable helpers first.

internal/domain (0% -> 100%):
- TestIsNil, TestCanTransition (all 30 state transitions), TestSentinelErrors,
  TestSignalTransitionsComplete

internal/learning (0% -> 26.2%):
- Refactored processGroup to extract 4 pure helpers: countOutcomes,
  computeConfidence, shouldValidate, shouldQuarantine
- TestWilsonLowerBound (monotonicity, edge cases, sample-size cap)
- TestCountOutcomes, TestComputeConfidence, TestShouldValidate,
  TestShouldQuarantine (table-driven)
- Remaining gap: extractPatterns/processGroup DB calls need make test-db

internal/policy (39% -> 50%):
- Extracted determineRoute from ClassifySignal (pure route logic)
- TestDetermineRoute (7 cases covering global/entity kill-switches, approval)
- Remaining gap: ClassifySignal/computeBlastRadius need DB mock

internal/knowledge (0% -> 14.2%):
- TestContentHash, TestStr, TestStrSlice, TestMapVal, TestToPGArray
- Documented latent bug: toPGArray doesn't escape " or \\ in tags
- Remaining gap: ingest* functions need make test-db

internal/actuator (0% -> 14.7%):
- TestSSHErrorClassString, TestClassifySSHError (11 cases incl. net.Error mock)
- TestParseProcedure, TestSetDefaultSSHTimeout
- Circuit breaker full state-machine test (open/close/reset/per-target)
- Remaining gap: ExecuteProcedure/ProvisionLXC need SSH+DB fixtures

internal/scheduler (0% -> 7.3%):
- TestParsePingLatency (Linux/macOS formats), TestAllowlistedScript
- TestEvaluateSeverity (threshold logic, crit:0 skip, signalKind fallback)
- Remaining gap: checkHTTP/checkTCP need httptest; runCheckPass needs DB

internal/notifier (0% -> 6.4%):
- TestHashToken, TestGenerateApprovalToken (HMAC re-derivation)
- Remaining gap: checkReaction/sendMatrixAlert need httptest; DB funcs need
  make test-db

All tests pass with -race. domain hits its 60% gate at 100%. The remaining
packages need integration tests (make test-db) and/or httptest-based tests
to reach their coverage gates — tracked as follow-up.

aa197190cd phase 3 review: fix broken error classification, stub checks, wasted uuid, token idempotency, dead code
- actuator/ssh.go: custom errorsAs chain broken — all SSH errors classified as SSHErrorOther.
  Replaced with standard errors.As + errors.Is.
- scheduler/scheduler.go: all four check functions were stubs returning healthy.
  Implemented real HTTP GET, TCP dial, unix.Statfs disk, and TLS cert expiry checks.
- learning/learning.go: uuid.NewV7() called unconditionally before ON CONFLICT upsert.
  Now looks up existing pattern first, reuses entity_id.
- notifier/notifier.go: removed dead var_, fixed token regeneration every 15s.
  Now skips if token_hash already set.
- phase3.go: removed dead GetPattern+dummy args call in PatchPattern.
- classify.go: removed unused var_ guard.

095a3967c4 phase 3: control loop — scheduler, actuator, learning, notifier, policy, API endpoints
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.<slug>)
- 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:
- Migration 009: knowledge_entities table with FTS indexes
- Config: scheduler/notifier/actuator/learning env vars
- sqlc: 30+ new Phase 3 queries
- Integration tests for all new endpoints
- go.sum updated with golang.org/x/sync
