- Merge all V1-V11 migration scripts into one idempotent init.sql
- Simplify ClickHouseSchemaInitializer to load single file
- Replace route_diagrams projection with in-memory caches:
  hashCache (routeId+instanceId → contentHash) warm-loaded on startup,
  graphCache (contentHash → RouteGraph) lazy-populated on access
- Eliminates 9M+ row scans on diagram lookups

- Jackson `JavaTimeModule` for `Instant` deserialization
- Communication: receives HTTP POST data from agents (executions, diagrams, metrics, logs), serves SSE event streams for config push/commands (config-update, deep-trace, replay, route-control)
- Maintains agent instance registry (in-memory) with states: LIVE → STALE → DEAD. Auto-heals from JWT claims on heartbeat/SSE after server restart. Route catalog falls back to ClickHouse stats for route discovery when registry has incomplete data.
- Storage: PostgreSQL for RBAC, config, and audit; ClickHouse for all observability data (executions, search, logs, metrics, stats, diagrams)
- Storage: PostgreSQL for RBAC, config, and audit; ClickHouse for all observability data (executions, search, logs, metrics, stats, diagrams). ClickHouse schema migrations in `clickhouse/*.sql`, run idempotently on startup by `ClickHouseSchemaInitializer`. Use `IF NOT EXISTS` for CREATE and ADD PROJECTION.
- Logging: ClickHouse JDBC set to INFO (`com.clickhouse`), HTTP client to WARN (`org.apache.hc.client5`) in application.yml
- Security: JWT auth with RBAC (AGENT/VIEWER/OPERATOR/ADMIN roles), Ed25519 config signing, bootstrap token for registration
- OIDC: Optional external identity provider support (token exchange pattern). Configured via admin API, stored in database (`server_config` table)
- User persistence: PostgreSQL `users` table, admin CRUD at `/api/v1/admin/users`
