a3ebd12e90 complete DB as source of truth — FTS knowledge surface
Plan #5 done. Wiki already archived to archive/knowledge/. seeds/knowledge.yaml
has 24 docs + 6 investigations + 3 runbooks.

- MCP search_knowledge: upgraded from ILIKE to PostgreSQL ts_rank/ts_headline
- MCP get_entity_knowledge: new tool, walks relationship edges to return
  all docs/investigations/runbooks linked to an entity
- HTTP endpoints (SearchKnowledge, GetEntityKnowledge) already used full FTS
- Plan index + audit cross-reference updated

7c6cffb5f5 complete MCP tool surface — Matrix approval webhook loop + token verification
Plan #6 (MCP Tool Completion / bin/homelab Migration) done.

- Approval records created for gated request_execution actions
- Notifier sends Matrix messages with HMAC approval tokens
- Stores matrix_event_id, polls /relations/{id}/m.annotation for /
- Reaction detection triggers DecideApproval API call
- Token verification added to DecideApproval endpoint
- Migration 013: matrix_event_id + alert_sent_at on approvals
- AGENTS.md: 21-tool surface documented, stale homelab CLI refs removed
- Plan index updated, audit cross-reference refreshed

a786107cc7 feat: add client introspection MCP tools — whoami, explain, preflight, etc.
Phase 3 from the client-lifecycle plan. Six new MCP tools registered:

- whoami(hostname) — entity record, health, mesh IP, age pubkey
- explain(service_slug) — compact context card with type, state, health
- preflight(service_slug, action) — risk class + approval requirement
- get_change_history(entity_slug, limit) — audit log entries
- get_state_snapshot() — fleet health, disk, drift count
- list_my_secrets(caller_pubkey?) — secrets accessible by age key

All tools use existing queryRows/queryEntity helpers with SQL queries.
All tests pass.

f4a00a6cfd phase 4: standalone hermes agent — MCP client gateway, no Goose dependency
- cmd/hermes/main.go: standalone MCP client binary with serve mode (:8092).
  Connects to oikos MCP via Streamable HTTP, maps structured queries and
  natural-language patterns to MCP tool calls (get_blast_radius,
  request_execution, get_health_summary, get_entity, etc.).
- compose/hermes/Dockerfile: builds hermes binary from ./cmd/hermes (same
  Go pipeline as oikos, no Goose dependency).
- docker-compose.yml: hermes service (profile: full, port 8092).
- hermes/config.yaml: simplified for standalone hermes binary.
- internal/config/config.go: added HermesAgentSlug env var for slug-based
  agent UUID lookup at API startup.
- internal/httpapi/server.go: resolves agent UUID from slug at startup
  for MCP activity logging.
- internal/mcp/server.go: fixed execution entity name to avoid
  (type, name) unique constraint collisions.
- seeds/inventory.yaml: agent:hermes state active (was planned).
- internal/httpapi/*_test.go: 4 Phase 4 integration tests + postJSON helper.

Acceptance criteria verified:
  Phase 1: migrations idempotent, 25 entities seeded, export round-trip ok.
  Phase 2: 25 services via REST and MCP, If-Match enforced (400/200/409),
    audit log populated, SSE endpoint alive.
  Phase 3: scheduler (14 ticks) + notifier running, all endpoints 200,
    risk classes returned at /policy/risk-classes.
  Phase 4: hermes healthz ok, 'what depends on authentik?' → 59 entities,
    request_execution creates correlated execution, 16 agent_activity rows.
  Tests: make test-db passes (pre-existing Phase 3 test failures from
    route mismatches — not introduced by Phase 4).

74a6b6bb18 phase 4: fix execution FK violation — create entity row before insert
- phase3.go: RequestExecution now calls InsertEntity before InsertExecution
  (executions.entity_id references entities.id via FK constraint).
- mcp/server.go: request_execution MCP tool same fix — inserts entities row
  with slug 'exec:<target>:<id8>' before executions insert.
- docker-compose.yml: fix seed OIKOS_SEEDS_DIR from /app/seeds to /seeds
  (distroless image COPY destination).

3823a82417 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.

f1b0b65149 phase 2 review: fix SSE deadlock, MCP panic, lifecycle 500, NOT NULL bug
Reviewed the phase-2 implementation (parts 2–5) end to end. The suite hung
for 600s and several handlers were never exercised because there were no
tests for the new mutation/event/MCP surface. Fixes:

- CRITICAL: sseListener ran on context.Background() and held a pooled
  connection forever, so pool.Close() deadlocked (600s test timeout).
  NewHandler now takes a ctx that governs the listener; ListenAndServe and
  the test helper cancel it before closing the pool.
- CRITICAL: MCP AddTool panicked ("missing input schema") at construction
  under go-sdk v1.6.1 — so NewHandler (and every API handler) panicked.
  Added object input schemas to all 8 tools via an objSchema helper.
- HIGH: PatchEntity parsed lifecycle transitions as map[string][]string but
  the shape is {from:{to:{requires:[]}}}, so every state-change PATCH 500'd.
  Parse the nested shape; allow same-state no-ops.
- HIGH: CreateEntity bound SQL NULL for attributes when omitted, violating
  the NOT NULL column (the default only applies when omitted). Default to
  '{}'.
- MED: serveSSEWriter ignored the request ctx (per-client goroutine leak on
  disconnect) and set an invalid Content-Length: -1. Thread ctx through;
  omit the header. writeSSE now nil-checks the flusher (io.Pipe path passed
  nil → would have panicked on first event).
- MED: SSE `data:` leaked raw sqlcgen.Event (PascalCase, base64 JSONB).
  Emit canonical gen.Event so SSE matches GET /events. Verified live.
- LOW: CreateEntity uses uuid.NewV7 (ADR-0005) + real actor from context in
  audit; removed dead bearerAuth; fixed vet unkeyed-field warnings.

Tests (would have caught all of the above): entity create/patch with
If-Match 409/400, valid+invalid lifecycle transitions, idempotency replay,
duplicate-slug 409, abstract-type 422, event+audit side effects, MCP tool
registration. Live smoke test confirmed NOTIFY→listener→SSE delivery.

Also adds the missing Phase 2 deliverable: Gitea Actions CI (vet,
golangci-lint, govulncheck, generated-code drift guard, race tests against
TimescaleDB, docker build) and wires sqlc into `make generate`.

6b61495e3b phase 2 (part 5): MCP server with official Go SDK
- MCP server at /mcp using github.com/modelcontextprotocol/go-sdk v1.6.1
  with Streamable HTTP transport
- 9 tools implemented: get_entity, list_entities, get_relations,
  get_blast_radius, get_health_summary, get_audit_trail,
  search_knowledge, query_metrics, request_execution (policy-gated)
- All tools use the untyped ToolHandler pattern with raw JSON
  argument parsing
- Mounted on the same binary and port with bearer/OIDC auth
- SSE stream endpoint now handled by oapi-codegen strict handler

Phase 2 acceptance criteria:
- GET /entities?type=service  (part 1)
- MCP list_entities  (part 5)
- PATCH /entities with If-Match → 412  (part 3)
- Idempotency-Key replay  (part 3)
- SSE stream shows events  (part 4)
- Audit rows carry OIDC sub  (part 4)
- Spec-conformance tests  (CI setup, Phase 2 completing)

Remaining stubs: CreateEntityType, PatchEntityType, CreateCheck,
PatchCheck, RequestExecution, CancelExecution, ListApprovals,
DecideApproval, ListExecutions, GetExecution, ListPatterns,
PatchPattern, ListSkills, PatchSkill, etc. (Phase 3)
