Note: M3 read-path invariant for M3-11 is **no-persist + existing enrollment audit only** — read-verb audit-log writes are deferred to M4 (see M3-05/06 notes), so M3-11 must not assert read-audit-log entries.

+# Scratchpad — FED-M3-04 Scope Service
+
+## Objective
+
+Implement `apps/gateway/src/federation/server/scope.service.ts` for the M3 inbound federation scope-enforcement pipeline.
+
+## Scope / Constraints
+
+- Task: FED-M3-04, issue #462.
+- Branch: `feat/federation-m3-scope-service` from `origin/main` @ 0.0.48.
+- Pure service: no direct DB access; native RBAC/data access is injected per evaluation call.
+- Reuse `parseFederationScope` from M2-03.
+- Workers do not edit `docs/federation/TASKS.md` per repo AGENTS.md.
+
+## Acceptance Criteria
+
+1. Resource allowlist and `excluded_resources` enforced.
+2. Native RBAC evaluated as `subjectUserId` through an injected evaluator.
+3. Scope filter intersection supports `include_teams` and `include_personal` without widening native RBAC.
+4. `max_rows_per_query` caps requested limits.
+5. Service returns `{ allowed: true, filter }` or a structured deny reason usable by M4 audit.
+6. Unit tests cover every deny path.
+
+## Plan
+
+1. Inspect existing federation scope/schema/auth guard contracts.
+2. Add pure `FederationScopeService` plus typed result/filter/deny interfaces.
+3. Add focused unit tests for happy paths, filter intersection, row cap, and deny paths.
+4. Export/register service for future verb controllers.
+5. Run situational tests, baseline gates, code review, then PR.
+
+## Budget
+
+- Provided model tier: sonnet.
+- Estimate from task row: 10K tokens.
+- Working cap assumption: keep implementation focused to FED-M3-04 surfaces only.
+
+## Progress
+
+- Intake complete; dirty base worktree avoided by creating isolated worktree at `/home/jarvis/src/mosaic-mono-v1-fed-m3-04`.
+- Project PRD and federation task spec reviewed.
+- Added `FederationScopeService` with structured allow/deny result types and injected native RBAC evaluator contract.
+- Added unit coverage for happy path, row cap, filter intersection, and every deny path.
+- Exported/registered the service for upcoming M3 verb controllers.
+
+## Verification Evidence
+
+- `pnpm --filter @mosaicstack/gateway test -- src/federation/server/__tests__/scope.service.spec.ts` — pass (10 tests before review update; 11 tests after adding include_personal no-leak coverage).
+- `pnpm build` — pass (23 successful tasks).
+- `pnpm typecheck` — pass (41 successful tasks; re-run after review update).
+- `pnpm lint` — pass (23 successful tasks; re-run after review update).
+- `pnpm format:check` — pass (re-run after review update).
+- `pnpm test` — pass after starting local `postgres`/`valkey` and running `pnpm --filter @mosaicstack/db db:push` for the DB-backed cross-user isolation suite (41 successful tasks; gateway 477 passed / 11 skipped).
+- Code review: `~/.config/mosaic/tools/codex/codex-code-review.sh --uncommitted` — approve, 0 findings.
+- Security review: `~/.config/mosaic/tools/codex/codex-security-review.sh --uncommitted` — risk none, 0 findings.
+
+## Risks / Blockers
+
+- Issue #462 is already closed in provider output; likely milestone tracking mismatch. Will still reference #462 in PR body unless orchestrator redirects.
+- Local full-test setup required `docker compose up -d postgres valkey` + `db:push`; containers were stopped with `docker compose down` after verification.

+# Scratchpad — fleet-personas spec timeout
+
+## Objective
+
+Raise the `@mosaicstack/mosaic` Vitest timeout to 30s at config level so filesystem-backed fleet drift-guard specs (`fleet-personas`, `fleet-profiles`, and siblings) stop false-reding under contended CI.
+
+## Plan
+
+1. Move timeout policy into `packages/mosaic/vitest.config.ts` with `testTimeout: 30_000`.
+2. Remove the narrower `fleet-personas.spec.ts` local override so PR #677 fixes the suite class, not one file.
+3. Run targeted fleet specs plus typecheck/lint/format gates.
+4. Commit, queue guard, push, PR update.
+
+## Evidence
+
+- `pnpm --filter @mosaicstack/mosaic test -- src/commands/fleet-personas.spec.ts` — pass (8 tests; initial narrow fix).
+- `pnpm typecheck` — pass (41 tasks; initial narrow fix).
+- `pnpm lint` — pass (23 tasks; initial narrow fix).
+- `pnpm format:check` — pass after formatting this scratchpad (initial narrow fix).
+- Package-wide timeout follow-up:
+  - `pnpm --filter @mosaicstack/mosaic test -- src/commands/fleet-personas.spec.ts src/commands/fleet-profiles.spec.ts` — pass (24 tests).
+  - `pnpm --filter @mosaicstack/mosaic test` — pass (44 files / 618 tests).
+  - `pnpm typecheck` — pass (41 tasks).
+  - `pnpm lint` — pass (23 tasks).
+  - `pnpm format:check` — pass.

+# FED-M3-07 — Capabilities Verb Scratchpad
+
+## Objective
+
+Implement `GET /api/federation/v1/capabilities` in `apps/gateway/src/federation/server/verbs/capabilities.controller.ts`.
+
+## Scope
+
+- Add read-only capabilities controller under federation server verbs.
+- Use `FederationAuthGuard` only; active grant is sufficient and no native RBAC/scope-service eval runs.
+- Response shape: `{ resources, excluded_resources, max_rows_per_query, supported_verbs }` derived from grant scope.
+- Register controller in `FederationModule`.
+- Unit-test happy path, defaults, no-context guard seam, and invalid scope handling.
+
+## Constraints / assumptions
+
+- Issue: #462.
+- Branch: `feat/federation-m3-verb-capabilities` from `origin/main` (`3eeed04e`).
+- Depends on M3-03 auth guard; guard attaches `request.federationContext.scope` after active-grant validation.
+- ASSUMPTION: `supported_verbs` is the M3 verb set from `@mosaicstack/types` (`list`, `get`, `capabilities`).
+- ASSUMPTION: `filters`/`rate_limit` are intentionally omitted for FED-M3-07 because the card’s response shape lists only the four required fields.
+- Budget: no explicit hard cap from orchestrator; working cap ~4K-8K tokens for card implementation + tests + PR cycle.
+
+## Plan
+
+1. Write controller unit tests first.
+2. Implement controller and module registration.
+3. Run scoped tests + typecheck/lint/format.
+4. Run Codex code/security review and remediate.
+5. Commit, queue guard, push, PR via wrapper.
+
+## Progress
+
+- 2026-06-24: Intake complete; fresh worktree created from origin/main.
+- 2026-06-24: Added `CapabilitiesController`, registered it in `FederationModule`, and added 5 unit tests.
+- 2026-06-24: Code/security reviews passed with no findings.
+
+## Tests run
+
+- `pnpm --filter @mosaicstack/gateway test -- capabilities.controller.spec.ts` — PASS (5 tests).
+- `pnpm --filter @mosaicstack/gateway typecheck` — PASS.
+- `pnpm --filter @mosaicstack/gateway lint` — PASS.
+- `pnpm format:check` — PASS.
+- `pnpm typecheck` — PASS (41/41 turbo tasks).
+- `pnpm lint` — PASS (23/23 turbo tasks).
+- `pnpm test` — FAIL in pre-existing/live-DB integration suite: `apps/gateway/src/__tests__/cross-user-isolation.test.ts` cleanup hit PostgreSQL connection/schema state for the `messages` table. Changed capabilities tests passed; failure is outside FED-M3-07 surface. No `fleet-personas.spec` flake encountered.
+
+## Review evidence
+
+- `~/.config/mosaic/tools/codex/codex-code-review.sh --uncommitted` — PASS/approve, no findings.
+- `~/.config/mosaic/tools/codex/codex-security-review.sh --uncommitted` — PASS, risk level none, no findings.
+
+## Risks / blockers
+
+- Full repo `pnpm test` may hit known `fleet-personas.spec` flake per orchestrator; ignore that specific flake if encountered.
+- Previous card saw local DB schema issue in `cross-user-isolation.test.ts`; scoped capabilities tests should be authoritative for this surface.
