+Mosaic supports three storage tiers: `local` (PGlite, single-host), `standalone` (PostgreSQL, single-host), and `federated` (PostgreSQL + pgvector + Valkey, multi-host). See [Federated Tier Setup](docs/federation/SETUP.md) for multi-user and production deployments, or [Migrating to Federated](docs/guides/migrate-tier.md) to upgrade from existing tiers.

+ * CaService — Step-CA client for federation grant certificate issuance.
+ *
+ * Responsibilities:
+ *  1. Build a JWK-provisioner One-Time Token (OTT) signed with the provisioner
+ *     private key (ES256/ES384/RS256 per JWK kty/crv) carrying Mosaic-specific
+ *     claims (`mosaic_grant_id`, `mosaic_subject_user_id`, `step.sha`) per the
+ *     step-ca JWK provisioner protocol.
+ *  2. POST the CSR + OTT to the step-ca `/1.0/sign` endpoint over HTTPS,
+ *     pinning the trust to the CA root cert supplied via env.
+ *  3. Return an IssuedCertDto containing the leaf cert, full chain, and
+ *     serial number.
+ *
+ * Environment variables (all required at runtime — validated in constructor):
+ *   STEP_CA_URL                   https://step-ca:9000
+ *   STEP_CA_PROVISIONER_KEY_JSON  JWK provisioner private key (JSON)
+ *   STEP_CA_ROOT_CERT_PATH        Absolute path to the CA root PEM
+ *
+ * Optional (only used for JWK PBES2 decrypt at startup if key is encrypted):
+ *   STEP_CA_PROVISIONER_PASSWORD  JWK provisioner password (raw string)
+ *
+ * Custom OID registry (PRD §6, docs/federation/SETUP.md):
+ *   1.3.6.1.4.1.99999.1  — mosaic_grant_id
+ *   1.3.6.1.4.1.99999.2  — mosaic_subject_user_id
+ *
+ * Fail-loud contract:
+ *   Every error path throws CaServiceError with a human-readable `remediation`
+ *   field. Silent OID-stripping is NEVER allowed — if the sign response does
+ *   not include the cert, we throw rather than return a cert that may be
+ *   missing the custom extensions.

+
+---
+
+## federated-test.stack.yml
+
+A self-contained Swarm stack that boots a federated-tier Mosaic gateway with co-located Postgres 17 (pgvector) and Valkey 8. This is a **test template** — production deployments will use a separate template with stricter resource limits and Docker secrets.
+
+### Deploy via Portainer UI
+
+1. Log into Portainer.
+2. Navigate to **Stacks → Add stack**.
+3. Set a stack name matching `STACK_NAME` below (e.g. `mos-test-1`).
+4. Choose **Web editor** and paste the contents of `federated-test.stack.yml`.
+5. Scroll to **Environment variables** and add each variable listed below.
+6. Click **Deploy the stack**.
+
+### Required environment variables
+
+| Variable             | Example                                 | Notes                                                    |
+| -------------------- | --------------------------------------- | -------------------------------------------------------- |
+| `STACK_NAME`         | `mos-test-1`                            | Unique per stack — used in Traefik router/service names. |
+| `HOST_FQDN`          | `mos-test-1.woltje.com`                 | Fully-qualified hostname served by this stack.           |
+| `POSTGRES_PASSWORD`  | _(generate randomly)_                   | Database password. Do **not** reuse between stacks.      |
+| `BETTER_AUTH_SECRET` | _(generate: `openssl rand -base64 32`)_ | BetterAuth session signing key.                          |
+| `BETTER_AUTH_URL`    | `https://mos-test-1.woltje.com`         | Public base URL of the gateway.                          |
+
+Optional variables (uncomment in the YAML or set in Portainer):
+
+| Variable                      | Notes                                                      |
+| ----------------------------- | ---------------------------------------------------------- |
+| `ANTHROPIC_API_KEY`           | Enable Claude models.                                      |
+| `OPENAI_API_KEY`              | Enable OpenAI models.                                      |
+| `OTEL_EXPORTER_OTLP_ENDPOINT` | Forward traces to a collector (e.g. `http://jaeger:4318`). |
+
+### Required external resources
+
+Before deploying, ensure the following exist on the Swarm:
+
+1. **`traefik-public` overlay network** — shared network Traefik uses to route traffic to stacks.
+   ```bash
+   docker network create --driver overlay --attachable traefik-public
+   ```
+2. **`letsencrypt` cert resolver** — configured in the Traefik Swarm stack. The stack template references `tls.certresolver=letsencrypt`; the name must match your Traefik config.
+3. **DNS A record** — `${HOST_FQDN}` must resolve to the Swarm ingress IP (or a Cloudflare-proxied address pointing there).
+
+### Deployed instances
+
+| Stack name   | HOST_FQDN               | Purpose                            |
+| ------------ | ----------------------- | ---------------------------------- |
+| `mos-test-1` | `mos-test-1.woltje.com` | DEPLOY-03 — first federation peer  |
+| `mos-test-2` | `mos-test-2.woltje.com` | DEPLOY-04 — second federation peer |
+
+### Image
+
+The gateway image is pinned by digest to `fed-v0.1.0-m1` (verified in DEPLOY-01). Update the digest in the YAML when promoting a new build — never use `:latest` or a mutable tag in Swarm.
+
+### Notes
+
+- This template boots a **vanilla M1-baseline gateway** in federated tier. Federation grants (Step-CA, mTLS) are M2+ scope and not included here.
+- Each stack gets its own Postgres volume (`postgres-data`) and Valkey volume (`valkey-data`) scoped to the stack name by Swarm.
+- `depends_on` is honoured by Compose but ignored by Swarm — healthchecks on Postgres and Valkey ensure the gateway retries until they are ready.

+# Portainer / Docker Swarm stack template — federated-tier test instance
+#
+# PURPOSE
+#   Deploys a single federated-tier Mosaic gateway with co-located Postgres
+#   (pgvector) and Valkey for end-to-end federation testing. Intended for
+#   mos-test-1.woltje.com and mos-test-2.woltje.com (DEPLOY-03/04).
+#
+# REQUIRED ENV VARS (set per-stack in Portainer → Stacks → Environment variables)
+#   STACK_NAME          Unique name for Traefik router/service labels.
+#                       Examples: mos-test-1, mos-test-2
+#   HOST_FQDN           Fully-qualified domain name served by this stack.
+#                       Examples: mos-test-1.woltje.com, mos-test-2.woltje.com

+#                       Generate: openssl rand -base64 32

+#   DNS A record        ${HOST_FQDN} → Swarm ingress IP (or Cloudflare proxy).
+#
+# IMAGE
+#   Pinned to sha-9f1a081 (main HEAD post-#488 Dockerfile fix). The previous
+#   pin (fed-v0.1.0-m1, sha256:9b72e2...) had a broken pnpm copy and could
+#   not resolve @mosaicstack/storage at runtime. The new digest was smoke-
+#   tested locally — gateway boots, imports resolve, tier-detector runs.
+#   Update digest here when promoting a new build.
+#
+# HEALTHCHECK NOTE (2026-04-21)
+#   Switched from busybox wget to node http.get on 127.0.0.1 (not localhost) to
+#   avoid IPv6 resolution issues on Alpine. Retries increased to 5 and
+#   start_period to 60s to cover the NestJS/GC cold-start window (~40-50s).
+#   restart_policy set to `any` so SIGTERM/clean-exit also triggers restart.
+#
+# NOTE: This is a TEST template — production deployments use a separate
+#       parameterised template with stricter resource limits and secrets.

 **Statement:** Jarvis operates across 3–4 workstations in two physical locations (home, USC). The user currently reaches back to a single jarvis-brain checkout from every session; a prior OpenBrain attempt caused cache, latency, and opacity pain. This mission builds asymmetric federation between Mosaic Stack gateways so that a session on a user's home gateway can query their work gateway in real time without data ever persisting across the boundary, with full multi-tenant isolation and standard-PKI (X.509 / Step-CA) trust management.

+- **CODE workstream**: M2-01 (DB migration) starts immediately — sonnet subagent on `feat/federation-m2-schema`. Then M2-02 → M2-09 sequentially with M2-04/M2-05/M2-06/M2-07 having interleaved CA/storage/grant dependencies.
+- **DEPLOY workstream**: DEPLOY-01 (image verify) → DEPLOY-02 (stack template) → DEPLOY-03/04 (mos-test-1/-2 deploy) → DEPLOY-05 (TEST-INFRA.md). Gated on Portainer wrapper PR (`PORTAINER_INSECURE` flag) merging first.
+- **Re-converge** at M2-10 (E2E test) once both workstreams ready.

+# Federated Tier Setup Guide
+
+## What is the federated tier?
+
+The federated tier is designed for multi-user and multi-host deployments. It consists of PostgreSQL 17 with pgvector extension (for embeddings and RAG), Valkey for distributed task queueing and caching, and a shared configuration across multiple Mosaic gateway instances. Use this tier when running Mosaic in production or when scaling beyond a single-host deployment.
+
+## Prerequisites
+
+- Docker and Docker Compose installed
+- Ports 5433 (PostgreSQL) and 6380 (Valkey) available on your host (or adjust environment variables)
+- At least 2 GB free disk space for data volumes
+
+## Start the federated stack
+
+Run the federated overlay:
+
+```bash
+docker compose -f docker-compose.federated.yml --profile federated up -d
+```
+
+This starts PostgreSQL 17 with pgvector and Valkey 8. The pgvector extension is created automatically on first boot.
+
+Verify the services are running:
+
+```bash
+docker compose -f docker-compose.federated.yml ps
+```
+
+Expected output shows `postgres-federated` and `valkey-federated` both healthy.
+
+## Configure mosaic for federated tier
+
+Create or update your `mosaic.config.json`:
+
+```json
+{
+  "tier": "federated",
+  "database": "postgresql://mosaic:mosaic@localhost:5433/mosaic",
+  "queue": "redis://localhost:6380"
+}
+```
+
+If you're using environment variables instead:
+
+```bash
+export DATABASE_URL="postgresql://mosaic:mosaic@localhost:5433/mosaic"
+export REDIS_URL="redis://localhost:6380"
+```
+
+## Verify health
+
+Run the health check:
+
+```bash
+mosaic gateway doctor
+```
+
+Expected output (green):
+
+```
+Tier: federated  Config: mosaic.config.json
+  ✓ postgres         localhost:5433       (42ms)
+  ✓ valkey           localhost:6380       (8ms)
+  ✓ pgvector         (embedded)           (15ms)
+```
+
+For JSON output (useful in CI/automation):
+
+```bash
+mosaic gateway doctor --json
+```
+
+## Troubleshooting
+
+### Port conflicts
+
+**Symptom:** `bind: address already in use`
+
+**Fix:** Stop the base dev stack first:
+
+```bash
+docker compose down
+docker compose -f docker-compose.federated.yml --profile federated up -d
+```
+
+Or change the host port with an environment variable:
+
+```bash
+PG_FEDERATED_HOST_PORT=5434 VALKEY_FEDERATED_HOST_PORT=6381 \
+  docker compose -f docker-compose.federated.yml --profile federated up -d
+```
+
+### pgvector extension error
+
+**Symptom:** `ERROR: could not open extension control file`
+
+**Fix:** pgvector is created at first boot. Check logs:
+
+```bash
+docker compose -f docker-compose.federated.yml logs postgres-federated | grep -i vector
+```
+
+If missing, exec into the container and create it manually:
+
+```bash
+docker exec <postgres-federated-id> psql -U mosaic -d mosaic -c "CREATE EXTENSION vector;"
+```
+
+### Valkey connection refused
+
+**Symptom:** `Error: connect ECONNREFUSED 127.0.0.1:6380`
+
+**Fix:** Check service health:
+
+```bash
+docker compose -f docker-compose.federated.yml logs valkey-federated
+```
+
+If Valkey is running, verify your firewall allows 6380. On macOS, Docker Desktop may require binding to `host.docker.internal` instead of `localhost`.
+
+## Key rotation (deferred)
+
+Federation peer private keys (`federation_peers.client_key_pem`) are sealed at rest using AES-256-GCM with a key derived from `BETTER_AUTH_SECRET` via SHA-256. If `BETTER_AUTH_SECRET` is rotated, all sealed `client_key_pem` values in the database become unreadable and must be re-sealed with the new key before rotation completes.
+
+The full key rotation procedure (decrypt all rows with old key, re-encrypt with new key, atomically swap the secret) is out of scope for M2. Operators must not rotate `BETTER_AUTH_SECRET` without a migration plan for all sealed federation peer keys.
+
+## OID Assignments — Mosaic Internal OID Arc
+
+Mosaic uses the private enterprise arc `1.3.6.1.4.1.99999` for custom X.509
+certificate extensions in federation grant certificates.
+
+**IMPORTANT:** This is a development/internal OID arc. Before deploying to a
+production environment accessible by external parties, register a proper IANA
+Private Enterprise Number (PEN) at <https://pen.iana.org/pen/PenApplication.page>
+and update these assignments accordingly.
+
+### Assigned OIDs
+
+| OID                   | Symbolic name                     | Description                                               |
+| --------------------- | --------------------------------- | --------------------------------------------------------- |
+| `1.3.6.1.4.1.99999.1` | `mosaic.federation.grantId`       | UUID of the `federation_grants` row authorising this cert |
+| `1.3.6.1.4.1.99999.2` | `mosaic.federation.subjectUserId` | UUID of the local user on whose behalf the cert is issued |
+
+### Encoding
+
+Each extension value is DER-encoded as an ASN.1 **UTF8String**:
+
+```
+Tag    0x0C        (UTF8String)
+Length 0x24        (36 decimal — fixed length of a UUID string)
+Value  <36 ASCII bytes of the UUID>
+```
+
+The step-ca X.509 template at `infra/step-ca/templates/federation.tpl`
+produces this encoding via the Go template expression:
+
+```
+{{ printf "\x0c\x24%s" .Token.mosaic_grant_id | b64enc }}
+```
+
+The resulting base64 value is passed as the `value` field of the extension
+object in the template JSON.
+
+### CA Environment Variables
+
+The `CaService` (`apps/gateway/src/federation/ca.service.ts`) requires the
+following environment variables at gateway startup:
+
+| Variable                       | Required | Description                                                          |
+| ------------------------------ | -------- | -------------------------------------------------------------------- |
+| `STEP_CA_URL`                  | Yes      | Base URL of the step-ca instance, e.g. `https://step-ca:9000`        |
+| `STEP_CA_PROVISIONER_PASSWORD` | Yes      | JWK provisioner password for the `mosaic-fed` provisioner            |
+| `STEP_CA_PROVISIONER_KEY_JSON` | Yes      | JSON-encoded JWK (public + private) for the `mosaic-fed` provisioner |
+| `STEP_CA_ROOT_CERT_PATH`       | Yes      | Absolute path to the step-ca root CA certificate PEM file            |
+
+Set these variables in your environment or secret manager before starting
+the gateway. In the federated Docker Compose stack they are expected to be
+injected via Docker secrets and environment variable overrides.
+
+### Fail-loud contract
+
+The CA service (and the X.509 template) are designed to fail loudly if the
+custom OIDs cannot be embedded:
+
+- The template produces a malformed extension value (zero-length UTF8String
+  body) when the JWT claims `mosaic_grant_id` or `mosaic_subject_user_id` are
+  absent. step-ca rejects the CSR rather than issuing a cert without the OIDs.
+- `CaService.issueCert()` throws a `CaServiceError` on every error path with
+  a human-readable `remediation` string. It never silently returns a cert that
+  may be missing the required extensions.

+## Pre-M2 — Test deployment infrastructure (FED-M2-DEPLOY)
+
+Goal: Two federated-tier gateways stood up on Portainer at `mos-test-1.woltje.com` and `mos-test-2.woltje.com` running the M1 release (`gateway:fed-v0.1.0-m1`). This is the test bed for M2 enrollment work and the M3 federation E2E harness. No federation logic exercised yet — pure infrastructure validation.
+
+> **Why now:** M2 enrollment requires a real second gateway to test peer-add flows; standing the test hosts up before M2 code lands gives both code and deployment streams a fast feedback loop.
+
+> **Parallelizable:** This workstream runs in parallel with the M2 code workstream (M2-01 → M2-13). They re-converge at M2-10 (E2E test).
+
+> **Tracking issue:** #482.

-_Deferred to mission planning when M1 is complete. Issue #461 tracks scope._
+Goal: An admin can create a federation grant; counterparty enrolls; cert is signed by Step-CA with SAN OIDs for `grantId` + `subjectUserId`. No runtime federation traffic flows yet (that's M3).

+# Migrating to the Federated Tier
+
+Step-by-step guide to migrate from `local` (PGlite) or `standalone` (PostgreSQL without pgvector) to `federated` (PostgreSQL 17 + pgvector + Valkey).
+
+## When to migrate
+
+Migrate to federated tier when:
+
+- Scaling from single-user to multi-user deployments
+- Adding vector embeddings or RAG features
+- Running Mosaic across multiple hosts
+- Requires distributed task queueing and caching
+- Moving to production with high availability
+
+## Prerequisites
+
+- Federated stack running and healthy (see [Federated Tier Setup](../federation/SETUP.md))
+- Source database accessible and empty target database at the federated URL
+- Backup of source database (recommended before any migration)
+
+## Dry-run first
+
+Always run a dry-run to validate the migration:
+
+```bash
+mosaic storage migrate-tier --to federated \
+  --target-url postgresql://mosaic:mosaic@localhost:5433/mosaic \
+  --dry-run
+```
+
+Expected output (partial example):
+
+```
+[migrate-tier] Analyzing source tier: pglite
+[migrate-tier] Analyzing target tier: federated
+[migrate-tier] Precondition: target is empty ✓
+  users: 5 rows
+  teams: 2 rows
+  conversations: 12 rows
+  messages: 187 rows
+  ... (all tables listed)
+[migrate-tier] NOTE: Source tier has no pgvector support. insights.embedding will be NULL on all migrated rows.
+[migrate-tier] DRY-RUN COMPLETE (no data written). 206 total rows would be migrated.
+```
+
+Review the output. If it shows an error (e.g., target not empty), address it before proceeding.
+
+## Run the migration
+
+When ready, run without `--dry-run`:
+
+```bash
+mosaic storage migrate-tier --to federated \
+  --target-url postgresql://mosaic:mosaic@localhost:5433/mosaic \
+  --yes
+```
+
+The `--yes` flag skips the confirmation prompt (required in non-TTY environments like CI).
+
+The command will:
+
+1. Acquire an advisory lock (blocks concurrent invocations)
+2. Copy data from source to target in dependency order
+3. Report rows migrated per table
+4. Display any warnings (e.g., null vector embeddings)
+
+## What gets migrated
+
+All persistent, user-bound data is migrated in dependency order:
+
+- **users, teams, team_members** — user and team ownership
+- **accounts** — OAuth provider tokens (durable credentials)
+- **projects, agents, missions, tasks** — all project and agent definitions
+- **conversations, messages** — all chat history
+- **preferences, insights, agent_logs** — preferences and observability
+- **provider_credentials** — stored API keys and secrets
+- **tickets, events, skills, routing_rules, appreciations** — auxiliary records
+
+Full order is defined in code (`MIGRATION_ORDER` in `packages/storage/src/migrate-tier.ts`).
+
+## What gets skipped and why
+
+Three tables are intentionally not migrated:
+
+| Table             | Reason                                                                                          |
+| ----------------- | ----------------------------------------------------------------------------------------------- |
+| **sessions**      | TTL'd auth sessions from the old environment; they will fail JWT verification on the new target |
+| **verifications** | One-time tokens (email verify, password reset) that have either expired or been consumed        |
+| **admin_tokens**  | Hashed tokens bound to the old environment's secret keys; must be re-issued                     |
+
+**Note on accounts and provider_credentials:** These durable credentials ARE migrated because they are user-bound and required for resuming agent work on the target environment. After migration to a multi-tenant federated deployment, operators may want to audit or wipe these if users are untrusted or credentials should not be shared.
+
+## Idempotency and concurrency
+
+The migration is **idempotent**:
+
+- Re-running is safe (uses `ON CONFLICT DO UPDATE` internally)
+- Ideal for retries on transient failures
+- Concurrent invocations are blocked by a Postgres advisory lock; the second caller will wait
+
+If a previous run is stuck, check for advisory locks:
+
+```sql
+SELECT * FROM pg_locks WHERE locktype='advisory';
+```
+
+If you need to force-unlock (dangerous):
+
+```sql
+SELECT pg_advisory_unlock(<lock_id>);
+```
+
+## Verify the migration
+
+After migration completes, spot-check the target:
+
+```bash
+# Count rows on a few critical tables
+psql postgresql://mosaic:mosaic@localhost:5433/mosaic -c \
+  "SELECT 'users' as table, COUNT(*) FROM users UNION ALL
+   SELECT 'conversations' as table, COUNT(*) FROM conversations UNION ALL
+   SELECT 'messages' as table, COUNT(*) FROM messages;"
+```
+
+Verify a known user or project exists by ID:
+
+```bash
+psql postgresql://mosaic:mosaic@localhost:5433/mosaic -c \
+  "SELECT id, email FROM users WHERE email='<your-email>';"
+```
+
+Ensure vector embeddings are NULL (if source was PGlite) or populated (if source was postgres + pgvector):
+
+```bash
+psql postgresql://mosaic:mosaic@localhost:5433/mosaic -c \
+  "SELECT embedding IS NOT NULL as has_vector FROM insights LIMIT 5;"
+```
+
+## Rollback
+
+There is no in-place rollback. If the migration fails:
+
+1. Restore the target database from a pre-migration backup
+2. Investigate the failure logs

+## Session 18 — 2026-04-19 — FED-M1-07 + FED-M1-08
+
+**Branches landed this run:** `feat/federation-m1-integration` (PR #476, FED-M1-07), `feat/federation-m1-migrate-test` (PR #477, FED-M1-08)
+**Branch active at end:** none — both PRs merged to main, branches deleted
+
+**M1 progress:** 8 of 12 tasks done. Remaining: M1-09 (regression e2e, haiku), M1-10 (security review, sonnet), M1-11 (docs, haiku), M1-12 (close + release, orchestrator).
+
+### FED-M1-07 — Integration tests for federated tier gateway boot
+
+Three test files under `apps/gateway/src/__tests__/integration/` gated by `FEDERATED_INTEGRATION=1`:
+
+- `federated-boot.success.integration.test.ts` — `detectAndAssertTier` resolves; `pg_extension` row for `vector` exists
+- `federated-boot.pg-unreachable.integration.test.ts` — throws `TierDetectionError` with `service: 'postgres'` when PG port is closed
+- `federated-pgvector.integration.test.ts` — TEMP table with `vector(3)` column round-trips data
+
+Independent code review (sonnet) returned VERDICT: B with two IMPORTANT items, both fixed in the same PR:
+
+- Port 5499 collision risk → replaced with `net.createServer().listen(0)` reserved-port helper
+- `afterAll` and `sql` scoped outside `describe` → moved both inside `describe.skipIf` block
+
+Independent surface verifier (haiku) confirmed all claims. 4/4 tests pass live; 4/4 skip cleanly without env var.
+
+### FED-M1-08 — Migration integration test (caught real P0 bug)
+
+`packages/storage/src/migrate-tier.integration.test.ts` seeds temp PGlite with cross-table data (users, teams, team_members, conversations, messages), runs `runMigrateTier`, asserts row counts + spot-checks. Gated by `FEDERATED_INTEGRATION=1`.
+
+**P0 bug surfaced and fixed in same PR:** `DrizzleMigrationSource.readTable()` returns Drizzle's camelCase keys (`emailVerified`, `userId`); `PostgresMigrationTarget.upsertBatch()` was using them verbatim as SQL identifiers, producing `column "emailVerified" does not exist` against real federated PG. The 32 unit tests in M1-05 missed this because both source and target were mocked. Fix: `normaliseSourceRow` now applies `toSnakeCase` (`/[A-Z]/g` → `_<lowercase>`), idempotent on already-snake_case keys.
+
+Code review (sonnet) returned VERDICT: B with one IMPORTANT and one MINOR, both fixed:
+
+- `createPgliteDbWithVector` and `runPgliteMigrations` were initially added to `@mosaicstack/db` public exports → moved to `packages/storage/src/test-utils/pglite-with-vector.ts` (avoids polluting prod consumers with WASM bundle)
+- `afterAll` did not call `cleanTarget` → added before connection close, ensuring orphan rows cleaned even on test panic
+
+Side change: `packages/storage/package.json` gained `"type": "module"` (codebase convention; required for `import.meta.url` in test-utils). All other workspace packages already declared this.
+
+### Process notes for this session
+
+- Review-then-verify pipeline now battle-tested: M1-08 reviewer caught the P0 bug + the public-API leak that the worker would have shipped. Without review, both would have gone to main.
+- Integration tests are paying for themselves immediately: M1-08 caught a real P0 in M1-05 that 32 mocked unit tests missed. Going forward, **at least one real-services integration test per code-mutating PR** should become a soft norm where feasible.
+- TASKS.md status updates continue to ride on the matching feature branch (avoids direct-to-main commits).
+
+**Followup tasks tracked but still deferred (no change):**
+
+- #7: `tier=local` hardcoded in gateway-config resume branches (~262, ~317)
+- #8: confirm `packages/config/dist` not git-tracked
+
+**Next:** FED-M1-09 — standalone regression e2e (haiku canary, ~4K). Verifies that the existing `standalone` tier behavior still works end-to-end on the federation-touched build, since M1 changes touched shared paths (storage, config, gateway boot).
+
+---
+
+## Session 19 — 2026-04-19 — FED-M1-09 → FED-M1-12 (M1 close)
+
+**Branches landed this run:** `feat/federation-m1-regression` (PR #478, M1-09), `feat/federation-m1-security-review` (PR #479, M1-10), `feat/federation-m1-docs` (PR #480, M1-11), `feat/federation-m1-close` (PR #481, M1-12)
+**Branch active at end:** none — M1 closed, all branches deleted, issue #460 closed, release tag `fed-v0.1.0-m1` published
+
+**M1 progress:** 12 of 12 tasks done. **Milestone complete.**
+
+### FED-M1-09 — Standalone regression canary
+
+Verification-only milestone. Re-ran the existing standalone/local test suites against current `main` (with M1-01 → M1-08 merged):
+
+- 4 target gateway test files: 148/148 pass (conversation-persistence, cross-user-isolation, resource-ownership, session-hardening)
+- Full gateway suite: 351 pass, 4 skipped (FEDERATED_INTEGRATION-gated only)
+- Storage unit tests: 85 pass, 1 skipped (integration-gated)
+- Top-level `pnpm test`: all green; only env-gated skips
+
+No regression in standalone or local tier. Federation M1 changes are non-disruptive.
+
+### FED-M1-10 — Security review (two rounds, 7 findings)
+
+Independent security review surfaced three high-impact and four medium findings; all fixed in same PR.
+
+**Round 1 (4 findings):**
+
+- MEDIUM: Credential leak via `postgres`/`ioredis` driver error messages (DSN strings) re-thrown by `migrate-tier.ts` → caller; `cli.ts:402` outer catch
+- MEDIUM: Same leak in `tier-detection.ts` `probePostgresMeasured` / `probePgvectorMeasured` → emitted as JSON by `mosaic gateway doctor --json`
+- LOW-MEDIUM: No advisory lock on `migrate-tier`; two concurrent invocations could both pass `checkTargetPreconditions` (non-atomic) and race
+- ADVISORY: `SKIP_TABLES` lacked rationale comment
+
+**Fixes:**
+
+- New internal helper `packages/storage/src/redact-error.ts` — regex `(postgres(?:ql)?|rediss?):\/\/[^@\s]*@` → `<scheme>://***@`. NOT exported from package public surface. 10 unit tests covering all schemes, multi-URL, no-creds, case-insensitive.
+- `redactErrMsg` applied at all 5 leak sites
+- `PostgresMigrationTarget.tryAcquireAdvisoryLock()` / `releaseAdvisoryLock()` using session-scoped `pg_try_advisory_lock(hashtext('mosaic-migrate-tier'))`. Acquired before preflight, released in `finally`. Dry-run skips. Non-blocking.
+- `SKIP_TABLES` comment expanded with rationale for skipped tables (TTL'd / one-time / env-bound) AND why `accounts` (OAuth) and `provider_credentials` (AI keys) are intentionally migrated (durable user-bound, not deployment-bound).
+
+**Round 2 (3 findings missed by first round):**
+
+- HIGH: Round 1 regex only covered `postgres` scheme, not `redis`/`rediss` — extended to `(postgres(?:ql)?|rediss?)`
+- HIGH: `probeValkeyMeasured` was missed in Round 1 → applied `redactErrMsg`
+- MEDIUM: `cli.ts:402` migrate-tier outer catch was missed in Round 1 → applied `redactErrMsg`
+
+**Process validation:** the two-round review pattern proved load-bearing for security work. A single review-then-fix cycle would have shipped the Valkey credential leak.
+
+### FED-M1-11 — Docs (haiku)
+
+- `docs/federation/SETUP.md` (119 lines): federated tier setup — what it is, prerequisites, docker compose start, mosaic.config.json snippet, doctor health check, troubleshooting
+- `docs/guides/migrate-tier.md` (147 lines): when to migrate, dry-run first, what migrates/skips with rationale, idempotency + advisory-lock semantics, no in-place rollback
+- `README.md` Configuration blurb linking to both
+- Runbook deferred to FED-M7 per TASKS.md scope rule
+
+### FED-M1-12 — Aggregate close (this PR)
+
+- Marked M1-12 done in TASKS.md
+- MISSION-MANIFEST.md: phase → "M1 complete", progress 1/7, M1 row done with PR range #470-#481, session log appended

+### Process learnings (M1 retrospective)
+
+1. **Two-round security review is non-negotiable for security work.** First round caught postgres credential leaks; second round caught equivalent valkey leaks the worker missed when extending the regex. Single-round would have shipped HIGH severity issues.
+2. **Real-services integration tests catch what mocked unit tests cannot.** M1-08 caught a P0 in M1-05 (camelCase column names) that 32 mocked unit tests missed because both source and target were mocked. Going forward: at least one real-services test per code-mutating PR where feasible.
+3. **Test-utils for live services co-locate with consumer, not in shared library.** M1-08 reviewer caught `createPgliteDbWithVector` initially being added to `@mosaicstack/db` public exports — would have polluted prod consumers with WASM bundle. Moved to `packages/storage/src/test-utils/`.
+4. **Per-task budgets including tests/review/docs more accurate than PRD's implementation-only estimates.** M1 PRD estimated 20K; actual ~74K. Future milestones should budget the full delivery cycle.
+5. **TASKS.md status updates ride feature branches, never direct-to-main.** Caught one violation early in M1; pattern held for all 12 tasks.
+6. **Subagent tier matters.** Code review needs sonnet-level reasoning (haiku missed deep issues in M1-04); claim verification (line counts, file existence) is fine on haiku.
+
+**Followup tasks still deferred (carry forward to M2):**
+
+- #7: `tier=local` hardcoded in gateway-config resume branches (~262, ~317)
+- #8: confirm `packages/config/dist` not git-tracked
+
+**Next mission step:** FED-M2 (Step-CA + grant schema + admin CLI). Per TASKS.md scope rule, M2 will be decomposed when it enters active planning. Issue #461 tracks scope.
+
+## Session 20 — 2026-04-21 — FED-M2 kickoff
+
+### Decisions
+
+- **Workstream split**: parallel CODE (M2-01..M2-13, ~72K) + DEPLOY (DEPLOY-01..DEPLOY-05, ~16K) tracks; re-converge at M2-10 E2E.
+- **Test hosts**: `mos-test-1.woltje.com` (querying side / Server A), `mos-test-2.woltje.com` (serving side / Server B). Wildcard `*.woltje.com` A→174.137.97.162 already exists; Traefik wildcard cert covers both subdomains. No DNS or cert work needed pre-deploy.
+- **Portainer access**: requires `PORTAINER_INSECURE=1` flag added to mosaic wrappers (self-signed cert at `https://10.1.1.43:9443`). PR pending on `feat/mosaic-portainer-tls-flag`.
+- **Image policy**: deploy by digest (immutable) per Mosaic policy. `gateway:fed-v0.1.0-m1` digest = `sha256:9b72e202a9eecc27d31920b87b475b9e96e483c0323acc57856be4b1355db1ec`.
+
+### DEPLOY-01 — image manifest verified
+
+- Tag `fed-v0.1.0-m1` exists at `git.mosaicstack.dev/mosaicstack/stack/gateway`
+- Digest: `sha256:9b72e202a9eecc27d31920b87b475b9e96e483c0323acc57856be4b1355db1ec`
+- 9 layers, ~530MB total
+- Use this digest in DEPLOY-02 stack template (do NOT reference `:fed-v0.1.0-m1` tag in stack — pin to digest)
+
+### Registry auth note
+
+- Gitea container registry uses Bearer token flow (`/v2/token?service=container_registry&scope=repository:<repo>:pull`)
+- Username: `jarvis` (NOT `mosaicstack`); password: `gitea.mosaicstack.token` from credentials.json
+- Direct `Authorization: Bearer <pat>` does NOT work — must exchange PAT for registry token first
+
+### Active PRs
+
+- #483 — docs: M2 mission planning (TASKS decomposition + manifest update) — CI running
+- (pending) `feat/mosaic-portainer-tls-flag` — wrapper PORTAINER_INSECURE flag (sonnet subagent in progress)
+- (pending) `feat/federation-m2-schema` — FED-M2-01 DB schema migration (sonnet subagent in progress)
+
+### MISSION-MANIFEST layout fix
+
+- Initial M2 commit had Test Infrastructure block inserted by lint-staged prettier between "Last Updated" and "Parent Mission" — split mission frontmatter
+- Fixed in 3d001fdb: moved Parent Mission back to frontmatter, kept Test Infrastructure as standalone H2 between Mission and Context
+
+## Session 21 — 2026-04-21/22 — DEPLOY-02 merged, gateway image bug discovered, M2-01 in remediation
+
+### PRs merged
+
+- **#483** — docs(federation): M2 mission planning (TASKS decomposition + manifest update)
+- **#484** — feat(mosaic-portainer): PORTAINER_INSECURE flag for self-signed TLS (wrapper sync to `~/.config/mosaic/tools/portainer/` done manually due to broken `mosaic upgrade` `set -o pipefail` on dash)
+- **#485** — feat(deploy): portainer stack template `deploy/portainer/federated-test.stack.yml` for federation test instances [DEPLOY-02]
+
+### Stack deployed (mos-test-1, mos-test-2)
+
+- Both stacks created on Portainer endpoint 3 (`local` Swarm @ 10.1.1.43, the only endpoint with traefik-public + woltje.com wildcard cert)
+- Swarm ID `l7z67tfpd4bvj4979ufpkyi50`
+- Image pinned to digest `sha256:9b72e202a9eecc27d31920b87b475b9e96e483c0323acc57856be4b1355db1ec`
+- Traefik labels target `${HOST_FQDN}` per env
+
+### CRITICAL FINDING — gateway image runtime-broken
+
+- `docker run` against `gateway:fed-v0.1.0-m1` fails immediately:  
+  `Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'dotenv' imported from /app/dist/main.js`
+- Root cause: `docker/gateway.Dockerfile` copies `/app/node_modules` from builder — but pnpm puts deps in the content-addressed `.pnpm/` store with symlinks at `apps/gateway/node_modules/*`. The runner stage misses the symlinks → Node can't resolve workspace deps.
+- M1 release was never runtime-tested as a stripped container; CI passed because tests run in dev tree where pnpm symlinks are intact.
+- **Fix in flight** (subagent `a78a9ab0ddae91fbc`): switch builder to `pnpm --filter @mosaic/gateway --prod deploy /deploy`, then runner copies `/deploy/node_modules` + `/deploy/dist` + `/deploy/package.json`.
+
+### M2-01 schema review verdict — NEEDS CHANGES
+
+- PR #486 (`feat/federation-m2-schema`) — independent reviewer (sonnet) found 2 real issues:
+  1. `federation_audit_log` time-range indexes missing `.desc()` on `created_at` (3 places)
+  2. Reserved columns missing per TASKS.md M2-01 spec: `query_hash`, `outcome`, `bytes_out` (M4 will write; spec said reserve now)
+- Also notes (advisory): subject_user_id correctly `text` (matches BetterAuth users.id; spec defect, not code defect); peer→grant cascade test not present (would be trivial to add)
+- **Remediation in flight** (subagent `a673dd9355dc26f82` in worktree `agent-a4404ac1`): apply DESC + reserved cols, regenerate migration in place (preferred) or stack 0009 (fallback), force-push, post PR comment.
+
+### Process notes
+
+- Branch race incident: schema subagent + wrapper subagent both ran in main checkout → schema files appeared on wrapper branch. Recovered by TaskStop, `git checkout --` to clean, respawned schema subagent with `isolation: "worktree"`. **Rule going forward:** any subagent doing code edits gets `isolation: "worktree"` unless work is single-file and the orchestrator confirms no other branch will touch overlapping files.
+- `pr-create.sh` shell-quotes backticks badly → use `tea pr create --repo mosaicstack/stack` directly (matches CLI-skill behavior). Will leave a followup to harden pr-create.sh.
+- Gitea registry auth: bearer-token exchange flow (`/v2/token?service=container_registry&scope=repository:<repo>:pull`) — direct `Authorization: Bearer <pat>` returns 401.
+- Portainer Swarm stack create endpoint: `POST /api/stacks/create/swarm/string?endpointId=<id>` (NOT `/api/stacks?type=1` — deprecated and rejected with 400).
+
+### In-flight at compaction boundary
+
+- Subagent `a78a9ab0ddae91fbc` — Dockerfile pnpm-deploy fix → PR (not yet opened at handoff)
+- Subagent `a673dd9355dc26f82` — M2-01 schema remediation (DESC + reserved cols) → force-push to PR #486
+- Both will trigger CI; orchestrator must independently re-review fixes (especially the security-adjacent schema work) per "always verify subagent claims" rule.
+
+### Next after subagents return
+
+1. Independent re-review of schema remediation (different subagent, fresh context)
+2. Merge #486 if green
+3. Merge Dockerfile fix PR if green → triggers Kaniko CI rebuild → capture new digest
+4. Update `deploy/portainer/federated-test.stack.yml` to new digest in a small PR
+5. Redeploy mos-test-1 + mos-test-2 (Portainer stack update via API)
+6. Verify HTTPS reachability + `/health` endpoint at both hosts
+7. DEPLOY-03/04 acceptance probes (`mosaic gateway doctor --json`, pgvector `vector(3)` round-trip)
+8. DEPLOY-05: author `docs/federation/TEST-INFRA.md`
+9. M2-02 (Step-CA sidecar) kicks off after image health is green

+ *  - Assumes the base schema (users table etc.) already exists in the target DB.
+ *  - All test rows use the `fed-m2-01-` prefix; cleanup in afterAll.
+ *
+ * Coverage:
+ *  1. Federation tables + enums apply cleanly against the existing schema.
+ *  2. Insert a sample user + peer + grant + audit row; verify round-trip.
+ *  3. FK cascade: deleting the user cascades to federation_grants.
+ *  4. FK set-null: deleting the peer sets federation_audit_log.peer_id to NULL.
