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
