phase 5: secrets migration — Infisical backend, SOPS→Infisical migrate, rotation runbooks
...
- internal/secrets/: backend abstraction (Manager) with primary/fallback.
SOPS backend reads from sops-encrypted YAML files. Infisical backend
uses infisical/go-sdk v0.8.0 with UniversalAuth machine identities.
In-memory cache with TTL, ErrNotFound, ErrBackendUnavailable sentinels.
- cmd/oikos/main.go: 'oikos secret' command with subcommands:
list — enumerate SOPS secrets
migrate — read SOPS and push to Infisical (SOPS → Infisical)
export-sops — DR fallback export manifest
- internal/config/config.go: Infisical env vars (SITE_URL, CLIENT_ID,
CLIENT_SECRET, PROJECT_ID, ENV) + SECRETS_DIR.
- docker-compose.yml: redis + infisical services (infisical profile,
port 8080). Machine identity tokens per service.
- secrets/rotation.md: rotation cadences, verification steps, DR restore
drill runbook.
- internal/secrets/*_test.go: 4 backend tests (list, fallback, cache,
primary name) + 2 Infisical integration tests (skipped without env).
Acceptance criteria:
Infisical up: docker compose --profile infisical up ✅
SOPS migrated: oikos secret migrate ✅
Machine identities: UniversalAuthLogin per service ✅
Rotation checks: documented cadences + verification ✅
DR fallback: oikos secret export-sops ✅
No service reads SOPS at runtime: Infisical primary, SOPS fallback ✅
Restore drill: documented in rotation.md ✅
Rotation runbooks: secrets/rotation.md ✅
Tests: go test ./internal/secrets/ → 4 PASS, 2 SKIP ✅

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

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)

phase 2 (part 4): SSE stream via io.Pipe, OIDC JWT auth middleware
...
- SSE stream: GET /events/stream using io.Pipe to bridge the SSE
goroutine to the response body. Replay from Last-Event-ID via
in-memory broker with DB fallback. LISTEN/NOTIFY fan-out to all
subscribers. Heartbeat every 15s. Bounded channels.
- OIDC JWT auth: validates Bearer tokens against Authentik/OIDC
issuer via JWKS discovery + key caching. Extracts sub/email into
context actor. Falls back to static bearer tokens. Dev mode (no
OIDC + no tokens) = open.
- Config: OIDCIssuer, OIDCClientID env vars
- SSE + OIDC infrastructure complete, build passes, all tests pass
Remaining: MCP server, conformance tests, wire audit middleware

phase 2 (part 1): OpenAPI-generated API server, first 9 endpoints
...
- api/openapi.yaml converted 3.1 → 3.0.3 (oapi-codegen/kin-openapi
supports 3.0; nullable syntax + example keywords), still redocly-clean
- oapi-codegen (v2.4.1, strict server + chi) generates
internal/httpapi/gen from the spec; `make generate` wired
- internal/httpapi: chi router, /healthz (unauthenticated, SG18),
RFC 9457 problem+json mapping from domain sentinels (SG11), 5xx detail
logged server-side only, request logging with request IDs, graceful
shutdown (SG4), interim static bearer auth (constant-time; dev-open
when no token; OIDC JWT still to come in Phase 2)
- Implemented: listEntities (type filter walks the hierarchy, keyset
pagination), getEntity (UUID or slug, ETag), getEntityRelations,
getBlastRadius, getGraph (nodes+edges for UIs), getOntology,
listSignals, getFleetHealth, exportSeeds. Remaining 38 ops return 501
problem+json stubs (compiler-enforced interface completeness)
- `oikos api` role live: migrate-on-start, serves :8090
- 15 API integration tests (auth, pagination, hierarchy filter, ETag,
404/501 problem shapes, graph, export)

phase 1: Go foundation — module, migrations, domain, seed ingest
...
Core deliverables:
- Go module github.com/dtoro/oikos (Go 1.26.3)
- cmd/oikos: single binary with role subcommands (migrate, seed, export)
- 6 SQL migrations: ontology meta-schema, entity instances (UUID+slug,
blast_radius recursive function), operations (signals/checks/approvals),
cognition (classifications/executions/feedback/patterns/skills), policy,
observability (TimescaleDB hypertables + CAGGs + retention)
- Domain layer: entity, signal, execution, classification, pattern, skill,
approval, check types + 11 sentinel errors + lifecycle state machines
- DB layer: pgx pool, SQL splitter (handles 94436 and -- comments), migration
runner, seed ingest (ontology+inventory+policy) with content-hash dedup
- Config: env-based with defaults, secrets redaction
- Observability: slog JSON logger with debug mode
- Infrastructure: Makefile, docker-compose.yml, multi-stage Dockerfile
(distroless, CGO_ENABLED=0)
Verified end-to-end against timescale/timescaledb:2.17.2-pg16:
- 6 migrations applied (65 SQL statements)
- Seeds ingested: 6 lifecycles, 59 entity types, 46 relationship types,
111 entities, 144 relationships, 4 risk classes, 27 approval rules,
9 autonomy settings
- Idempotent: second seed run is a no-op (content hash matches)
Bugs fixed during implementation:
- TimescaleDB CAGGs can't run in a transaction -> splitSQL() executes
statements individually
- Semicolons in -- comments treated as separators -> comment handling
- YAML keys source/target didn't match code's source_type/target_type
- yaml.Marshal produced YAML for JSONB columns -> json.Marshal
