phase 4: hermes agent — MCP tools, activity logging, 'all' role, wiring fixes
- mcp/server.go: 7 new tools (get_signal_history, get_patterns, get_skills,
request_execution, get_trend, get_event_timeline, get_agent_activity),
agent_activity logging middleware on every tool call.
- phase3.go: QueryAgentActivity REST handler implemented (was stub).
Fixed scan count mismatch in ListSkills/PatchSkill/ListSkillVersions
(13 cols → 12 targets). Fixed AgentActivity cursor pagination
(lexicographic → integer comparison). Fixed s.Slug → s.Name in log.
- cmd/oikos/main.go: 'all' role now runs api + scheduler + notifier in
one process. Replaced nil SchedulerRunner/NotifierRunner with direct
scheduler.RunnerForMain() / notifier.RunnerForMain() imports.
Added runWithPool helper for standalone scheduler/notifier roles.
- internal/config/config.go: added HermesAgentID env var.
- internal/httpapi/server.go: pass HermesAgentID to MCP handler.
- docker-compose.yml: added scheduler and notifier services (dev profile).
- hermes/: config.yaml, SOUL.md, skills/homelab-ops/SKILL.md.
- Cleaned up: scheduler/init.go dead code, mcp/server.go pgx import guard.

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
