-## Architecture and Code Conventions
-
-1. Gateway is the single API surface; all clients connect through it.
-2. Pi SDK is ESM-only; gateway and CLI code must remain ESM.
-3. Use `"type": "module"`, NodeNext module resolution, and `.js` extensions in imports.
-4. Keep typed Socket.IO events in `@mosaicstack/types` to enforce client/server contracts.
-5. Import OTEL tracing before NestJS bootstrap (`import './tracing.js'`).
-6. Use explicit `@Inject()` decorators in NestJS because tsx/esbuild does not emit decorator metadata.
-7. Keep DTOs in `*.dto.ts` files at module boundaries.
-8. BetterAuth owns authentication tables; their schema is defined in `@mosaicstack/db`.
-9. Create a task-specific scratchpad for non-trivial work.
+1. Gateway is the single API surface — all clients connect through it
+2. Pi SDK is ESM-only — gateway and CLI must use ESM
+3. Socket.IO typed events defined in `@mosaicstack/types` enforce compile-time contracts
+4. OTEL auto-instrumentation loads before NestJS bootstrap
+5. BetterAuth manages auth tables; schema defined in `@mosaicstack/db`
+6. Docker Compose provides PG (5433), Valkey (6380), OTEL Collector (4317/4318), Jaeger (16686)
+7. Explicit `@Inject()` decorators required in NestJS (tsx/esbuild doesn't emit decorator metadata)

 ## Development Workflow

-Requirements: Node.js 20+, pnpm 10.6.2, and Docker Compose when optional local services are needed.
-
 ```bash
-pnpm install --frozen-lockfile
-pnpm preflight
-
-# Optional local queue service only; do not start the full Compose stack.
-docker compose up -d valkey
+docker compose up -d          # Infrastructure
+pnpm install                  # Dependencies
+pnpm typecheck && pnpm lint && pnpm format:check  # Quality gates
 ```

-The pre-push hook requires:
+## Repo-Specific Notes

-```bash
-pnpm preflight && pnpm typecheck && pnpm lint && pnpm format:check
-```
-
-Software delivery also requires the applicable tests. Common repository commands are:
-
-```bash
-pnpm typecheck     # TypeScript checks across the workspace
-pnpm lint          # ESLint across the workspace
-pnpm test          # Checkout tests and package Vitest suites
-pnpm format:check  # Prettier check
-pnpm build         # Build all packages and applications
-```
-
-## Database and Local Runtime Safety
-
- Current local data-layer work uses in-process PGlite; leave `DATABASE_URL` unset.
- PostgreSQL execution is held until KBN-101-00, KBN-101-03, and KBN-101-05 land.
- Do not invoke a migration runner, initialization SQL, or the Compose PostgreSQL service from this checkout.
- Do not start Gateway/Web or run root `pnpm dev` as a local PGlite route. The current dotenv loader can inherit a daemon PostgreSQL DSN; KBN-101-02 must make that path fail closed first.
- Migration artifact generation is offline and does not authorize PostgreSQL access:
-
-```bash
-pnpm --filter @mosaicstack/db db:generate
-```

-The checked-in Compose PostgreSQL service mounts legacy initialization SQL and is **not** a
-current PostgreSQL, standalone, or federated developer route. Do not start it with Compose,
-invoke initialization SQL, or treat the planned migrator as currently executable.
+Docker Compose provides:

-**Held future activation procedure — non-operative and no current command authority until KBN-101-00, KBN-101-03, and KBN-101-05
-land:** external bootstrap → TLS/roles → `mosaic-db-migrator --run` →
-`mosaic-db-migrator --verify` → Gateway/Compose readiness. The future deployment artifacts—not
-this README—will provide the reviewed commands and secret-consumer interface.
-
-For local data-layer work, PGlite needs no PostgreSQL service. The optional Compose command above
-starts only Valkey; OTEL Collector and Jaeger may likewise be started individually if needed,
-without starting PostgreSQL. A Gateway/Web local process is not currently a safe PGlite route:
-its unguarded dotenv loader may inherit a daemon PostgreSQL DSN. Do not use root `pnpm dev` or a
-Gateway start command until KBN-101-02 makes that state fail closed.

- * Task Five, Step Three — legacy port operations fail closed under pi-rpc (direct valid-input).

- * six per-operation inner `if (this.mode === 'pi-rpc')` guards are unexercised — a mutation that
- * deletes one of them SURVIVES for lack of a test that drives that operation. This group closes
- * that gap the right way: it drives each of the six operations DIRECTLY, in pi-rpc mode, with a
- * valid branded {@link OwnedConversationContext} and valid input, against a recording embedded
- * stub whose method returns a distinguishable `ok:true` success and increments a per-op counter.
- *
- * For each operation:
- *  - pi-rpc test asserts the exact frozen `{ ok:false, code:'runtime_unsupported', retryable:false }`
- *    result AND that the embedded stub was touched zero times (no effects);
- *  - the paired legacy test proves that same stub method IS reached and returns its distinguishable
- *    success when the mode does not refuse — so the pi-rpc zero-invocation assertion is meaningful,
- *    not vacuously true because the stub could never be called.
- *
- * Deleting ONLY one operation's inner guard makes THAT operation's pi-rpc test behaviorally RED
- * (the router returns the embedded `ok:true` value and records the call), with every outer guard
- * and the other five inner guards intact. `next` is untouched; nothing here changes production.

-/**
- * Task Five, Step Two — group 1 (real Nest module-graph readiness).
- *
- * The unit suite above constructs the router directly. This group drives the SAME contract
- * through a real NestJS graph: it imports the production `HarnessModule` (the proven-booting
- * idiom from harness.controller.spec.ts) so the router resolves the REAL, empty `HarnessRegistry`
- * via the real `HARNESS_REGISTRY` token, then runs the router's `OnModuleInit` through the Nest
- * lifecycle (`moduleRef.init()`). Red-first: the router is an unimplemented stub whose
- * `onModuleInit` throws a generic Error, so:
- *   - readiness cases fail because the graph never comes up (init rejects), and
- *   - fail-closed cases fail because a generic stub throw is NOT the SPECIFIC typed
- *     `ChatRuntimeUnavailableError` (reason/code) the contract demands — a stub that
- *     "throws anything" cannot mask these greens.
- * The router is NOT wired into a production module yet, so it is provided here via a factory
- * over the real registry token. Importing the real `ChatModule` bare is deliberately avoided:
- * it injects `AgentService` without importing `AgentModule`, so its graph fails to RESOLVE — a
- * collection/DI error, not a behavioural red. `next` is untouched; nothing here implements the router.

-/**
- * Task Five, Step Two — group 1b (production ChatModule wiring, declaration proof).
- *
- * Correction #1 (Scrappy fe3e02) asked for a red that imports the real `ChatModule` and calls
- * `module.init()`. Investigated and found impractical/masking-prone: `ChatModule` provides
- * `ChatGateway`, whose 10-argument constructor injects app-global providers (AgentService, AUTH,
- * BRAIN, RoutingEngineService) plus the Commands/GC/Mcp/Reload subsystems across a forwardRef
- * cycle. Booting it in isolation is a full-app integration boot — "override only unrelated
- * dependencies" balloons into faking ~4 subsystems, and `overrideProvider` cannot even grant the
- * cross-module export-scope visibility ChatGateway needs (probe: `ChatGateway` unresolved at
- * `CommandExecutorService`). That is exactly the STOP-and-return branch of the directive.
- *
- * The faithful, unmaskable cover instead of a fragile boot: read the PRODUCTION `ChatModule`'s own
- * Nest `@Module` metadata to prove it DECLARES the exclusive router provider and imports the real
- * `HarnessModule` (the genuine registry source). This inspects the actual module object — not
- * source text, not a test factory — so nothing can mask it. Group 1 above separately proves the
- * router RESOLVES against the real, empty `HarnessRegistry` through the Nest lifecycle; the union
- * of the two covers "the router is wired through ChatModule to the real registry" without the
- * impractical single-graph boot. RED today (ChatModule provides only ChatGateway and imports only
- * CommandsModule); GREEN once Step Three registers the router and imports HarnessModule.

- * Task Five, Step Two — group 2 (WHOLE production `AppModule` boot, legacy end-to-end wiring).
- *
- * The groups above bound away the heavy cycle to isolate the router. This group instead boots the
- * ACTUAL production `AppModule` (the exact graph `main.ts` runs) in the default LEGACY chat-runtime
- * mode, overriding ONLY the storage/network side-effect adapters so the boot is bounded and offline
- * — never the chat/router/harness/reload/commands surface under test. The bounded fakes are exactly
- * the disk/network leaves:
- *   - `ProviderService` (the #1 hang risk: its real `onModuleInit` starts an unref'd health-check
- *     `setInterval` and fetches Ollama over HTTP) → inert no-op instance;
- *   - `DB_HANDLE`/`DB` → a fake Drizzle-shaped handle that satisfies `runPgliteMigrations` (the local
- *     tier's `DatabaseModule.onModuleInit`) AND `DefaultRoutingRulesSeed.onModuleInit` (which reads a
- *     system-rule count — the fake reports rules already present so the seed insert is skipped),
- *     opening no real database;
- *   - `STORAGE_ADAPTER`/`MEMORY`/`MEMORY_ADAPTER`/`AUTH`/`BRAIN`/`LOG_SERVICE` → inert fakes so no
- *     storage/auth/log backend is contacted.
- * Local tier (the repo's `mosaic.config.json`) already disables BullMQ/Redis and the queue handles;
- * Discord/Telegram/MCP plugins are env-gated and disarmed by deleting their tokens. Nothing about the
- * router, `ChatModule`, `HarnessModule`, or `ChatGateway` is faked — those come from the REAL graph.
- *
- * The boot+init MUST SUCCEED cleanly (proven by `beforeAll` completing and the ChatGateway test
- * passing). Red-first: on this branch `ChatRuntimeRouter` is registered in NO module (ChatModule
- * provides only ChatGateway), so `moduleRef.get(ChatRuntimeRouter)` throws `UnknownElementException`
- * — a WIRING gap, NOT an init failure. That single retrieval is the intended behavioural red; it
- * flips green once Step Three registers the exclusive router. The ChatGateway retrieval and its
- * browser-facing method surface are asserted alongside and pass today, pinning that the boot itself
- * is healthy so the router failure cannot be mistaken for a mis-shaped fake or an unbounded side
- * effect.
