 - **Daemon** (`internal/daemon/`): Local agent runtime — auto-detects available CLIs (claude, codex), registers runtimes, polls for tasks, routes by provider.
 - **CLI** (`internal/cli/`): Shared helpers for the `multica` CLI — API client, config management, output formatting.
 - **Events** (`internal/events/`): Internal event bus for decoupled communication between handlers and services.
-- **Database**: sqlc generates Go code from SQL in `pkg/db/queries/` → `pkg/db/generated/`. Migrations in `migrations/`.
+- **Logging** (`internal/logger/`): Structured logging via slog. `LOG_LEVEL` env var controls level (debug, info, warn, error).
+- **Database**: PostgreSQL with pgvector extension (`pgvector/pgvector:pg17`). sqlc generates Go code from SQL in `pkg/db/queries/` → `pkg/db/generated/`. Migrations in `migrations/`.
 - **Routes** (`cmd/server/router.go`): Public routes (auth, health, ws) + protected routes (require JWT) + daemon routes (unauthenticated, separate auth model).

+### CI Requirements
+
+CI runs on Node 22 and Go 1.24 with a `pgvector/pgvector:pg17` PostgreSQL service. See `.github/workflows/ci.yml`.

 ### Worktree Support
 
 All checkouts share one PostgreSQL container. Isolation is at the database level — each worktree gets its own DB name and unique ports via `.env.worktree`. Main checkouts use `.env`.
