+# Gateway Security Hardening Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Finish the requested gateway security hardening fixes in the existing `fix/gateway-security` worktree and produce a PR-ready branch.
+
+**Architecture:** Tighten NestJS gateway boundaries in-place by enforcing auth guards, session validation, ownership checks, DTO validation, and Fastify security defaults. Preserve the current module structure and existing ESM import conventions.
+
+**Tech Stack:** NestJS 11, Fastify, Socket.IO, Better Auth, class-validator, Vitest, pnpm, TypeScript ESM
+
+---
+
+### Task 1: Reconcile Security Tests
+
+**Files:**
+
+- Modify: `apps/gateway/src/chat/__tests__/chat-security.test.ts`
+- Modify: `apps/gateway/src/__tests__/resource-ownership.test.ts`
+
+**Step 1: Write the failing test**
+
+- Encode the requested DTO constraints and socket-auth contract exactly.
+
+**Step 2: Run test to verify it fails**
+
+Run: `pnpm --filter @mosaic/gateway test -- src/chat/__tests__/chat-security.test.ts src/__tests__/resource-ownership.test.ts`
+
+Expected: FAIL on current DTO/helper mismatch.
+
+**Step 3: Write minimal implementation**
+
+- Update DTO/helper/controller code only where tests prove a gap.
+
+**Step 4: Run test to verify it passes**
+
+Run the same command and require green.
+
+### Task 2: Align Gateway Runtime Hardening
+
+**Files:**
+
+- Modify: `apps/gateway/src/conversations/conversations.dto.ts`
+- Modify: `apps/gateway/src/chat/chat.dto.ts`
+- Modify: `apps/gateway/src/chat/chat.gateway-auth.ts`
+- Modify: `apps/gateway/src/chat/chat.gateway.ts`
+- Modify: `apps/gateway/src/main.ts`
+- Modify: `apps/gateway/src/app.module.ts`
+
+**Step 1: Verify remaining requested deltas**
+
+- Confirm code matches requested guard, rate limit, helmet, body limit, env validation, and CORS settings.
+
+**Step 2: Apply minimal patch**
+
+- Keep changes scoped to requested behavior only.
+
+**Step 3: Run targeted tests**
+
+Run: `pnpm --filter @mosaic/gateway test -- src/chat/__tests__/chat-security.test.ts src/__tests__/resource-ownership.test.ts`
+
+Expected: PASS.
+
+### Task 3: Verification, Review, and Delivery
+
+**Files:**
+
+- Create: `docs/reports/code-review/gateway-security-20260313.md`
+- Create: `docs/reports/qa/gateway-security-20260313.md`
+- Modify: `docs/scratchpads/gateway-security-20260313.md`
+
+**Step 1: Run baseline gates**
+
+Run:
+
+```bash
+pnpm typecheck
+pnpm lint
+```
+
+**Step 2: Perform manual code review**
+
+- Record correctness/security/testing/doc findings.
+
+**Step 3: Commit and publish**
+
+Run:
+
+```bash
+git add -A
+git commit -m "fix(gateway): security hardening — auth guards, ownership checks, validation, rate limiting"
+git push origin fix/gateway-security
+```
+
+**Step 4: Open PR and notify**
+
+- Open PR titled `fix(gateway): security hardening — auth guards, ownership checks, validation, rate limiting`
+- Run `openclaw system event --text "PR ready: mosaic-mono-v1 fix/gateway-security — 7 security fixes" --mode now`
+- Remove worktree after PR is created.

+# Authentik SSO Setup
+
+## Create the Authentik application
+
+1. In Authentik, create an OAuth2/OpenID Provider.
+2. Create an Application and link it to that provider.
+3. Copy the generated client ID and client secret.
+
+## Required environment variables
+
+Set these values for the gateway/auth runtime:
+
+```bash
+AUTHENTIK_CLIENT_ID=your-client-id
+AUTHENTIK_CLIENT_SECRET=your-client-secret
+AUTHENTIK_ISSUER=https://authentik.example.com
+```
+
+`AUTHENTIK_ISSUER` should be the Authentik base URL, for example `https://authentik.example.com`.
+
+## Redirect URI
+
+Configure this redirect URI in the Authentik provider/application:
+
+```text
+{BETTER_AUTH_URL}/api/auth/callback/authentik
+```
+
+Example:
+
+```text
+https://mosaic.example.com/api/auth/callback/authentik
+```
+
+## Test the flow
+
+1. Start the gateway with `BETTER_AUTH_URL` and the Authentik environment variables set.
+2. Open the Mosaic login flow and choose the Authentik provider.
+3. Complete the Authentik login.
+4. Confirm the browser returns to Mosaic and a session is created successfully.

+- `apps/gateway/src/chat/chat.gateway.ts`
+- `apps/gateway/src/conversations/conversations.dto.ts`

+
+## Findings
+
+- No blocker findings in the final changed surface.
+
+## Review Summary
+
+- Correctness: socket auth helper now returns Better Auth session data unchanged, and gateway disconnects clients whose handshake does not narrow to a valid session payload
+- Security: conversation role validation now rejects `system`; conversation content ceiling is 32k; chat request ceiling remains 10k
+- Testing: targeted auth, ownership, and DTO regression tests pass
+- Quality: `pnpm typecheck`, `pnpm lint`, and `pnpm format:check` all pass after the final edits
+
+## Residual Risk
+
+- `chat.gateway.ts` uses local narrowing around an `unknown` session result because the requested helper contract intentionally returns `unknown`.

+# QA Report — Gateway Security Hardening
+
+## Scope
+
+- Chat HTTP auth guard hardening
+- Chat WebSocket session validation
+- DTO validation rules for chat and conversation payloads
+- Ownership regression coverage for by-id routes
+
+## TDD
+
+- Required: yes
+- Applied: yes
+- Red step: targeted tests failed on socket session reshaping and DTO role/length mismatches
+- Green step: targeted tests passed after runtime and DTO alignment
+
+## Baseline Verification
+
+| Command | Result | Evidence |
+| --- | --- | --- |
+| `pnpm --filter @mosaic/gateway test -- src/chat/__tests__/chat-security.test.ts src/__tests__/resource-ownership.test.ts` | pass | 3 test files passed, 20 tests passed |
+| `pnpm typecheck` | pass | turbo completed 18/18 package typecheck tasks |
+| `pnpm lint` | pass | turbo completed 18/18 package lint tasks |
+| `pnpm format:check` | pass | `All matched files use Prettier code style!` |
+
+## Situational Verification
+
+| Acceptance Criterion | Verification Method | Evidence |
+| --- | --- | --- |
+| Chat controller requires auth and current-user context | source assertion test | `chat-security.test.ts` checks `@UseGuards(AuthGuard)` and `@CurrentUser() user: { id: string }` |
+| WebSocket handshake requires Better Auth session | unit tests for `validateSocketSession()` | null handshake returns `null`; valid handshake returns original session object |
+| Conversation messages reject non-user/assistant roles | class-validator test | `system` role fails validation |
+| Conversation messages enforce a 32k max length | class-validator test | `32_001` chars fail validation |
+| Chat request payload enforces a 10k max length | class-validator test | `10_001` chars fail validation |
+| By-id routes reject cross-user access | ownership regression tests | conversations, projects, missions, tasks each raise `ForbiddenException` for non-owner access |
+
+## Residual Risk
+
+- No live HTTP or WebSocket smoke test against a running gateway process was executed in this session.

+- Task: P5-001 / issue #41
+- Branch: feat/p5-plugin-host
+- Objective: add global NestJS plugin host module, wire Discord import, register active plugins from env, and attach to AppModule.
+- TDD: skipped as optional for module wiring/integration work; relying on targeted typecheck/lint and module-level situational verification.
+- Constraints: ESM .js imports, explicit @Inject(), follow existing gateway patterns, do not touch TASKS.md.
+
+## Progress Log
+
+- 2026-03-13: session started in worktree; loading gateway/plugin package context.
+- 2026-03-13: implemented initial plugin module, service, interface, and AppModule wiring; pending verification.
+- 2026-03-13: added `@mosaic/discord-plugin` as a gateway workspace dependency and regenerated `pnpm-lock.yaml`.
+- 2026-03-13: built gateway dependency chain so workspace packages exported `dist/*` for clean TypeScript resolution in this fresh worktree.
+- 2026-03-13: verification complete.

+# Gateway Security Hardening Scratchpad
+
+## Metadata
+
+- Date: 2026-03-13
+- Worktree: `/home/jwoltje/src/mosaic-mono-v1-worktrees/sec-remediation`
+- Branch: `fix/gateway-security`
+- Scope: Finish 7 requested gateway security fixes without switching branches or worktrees
+- Related tracker: worker task only; `docs/TASKS.md` is orchestrator-owned and left unchanged
+- Budget assumption: no explicit token cap; keep scope limited to requested gateway/auth/validation hardening
+
+## Objective
+
+Complete the remaining gateway security hardening work:
+
+1. Chat HTTP auth guard enforcement
+2. Chat WebSocket session validation
+3. Ownership checks on by-id CRUD routes
+4. Global validation pipe and DTO enforcement
+5. Rate limiting
+6. Helmet security headers
+7. Body limit and env validation
+
+## Plan
+
+1. Reconcile current worktree state against requested fixes.
+2. Patch or extend tests first for DTO/auth behavior mismatches.
+3. Implement minimal code changes to satisfy tests and requested behavior.
+4. Run targeted gateway tests.
+5. Run baseline gates: `pnpm typecheck`, `pnpm lint`.
+6. Perform manual code review and record findings.
+7. Commit, push branch, open PR, send OpenClaw event, remove worktree.
+
+## Progress Log
+
+### 2026-03-13T00:00 local
+
+- Loaded required Mosaic/global/runtime instructions and applicable skills.
+- Confirmed active worktree is `sec-remediation` and branch is already dirty with prior session changes.
+- Identified remaining gaps: DTO validation mismatch and non-requested socket auth helper typing/behavior drift.
+
+## TDD Notes
+
+- Required: yes. This is security/auth/permission logic.
+- Approach: update targeted unit tests first, verify failure, then patch code minimally.
+
+## Verification Log

+## Review Log
+
+- Manual review completed against auth, authorization, validation, and runtime hardening requirements.
+- No blocker findings remained after remediation.
+
+## Risks / Blockers
+
+- Repository instructions conflict on PR merge behavior; user explicitly instructed PR-only, no merge. Follow user instruction.
+- Existing worktree contains prior-session modifications; do not revert unrelated changes.
+- `missions` and `tasks` currently depend on project ownership because the schema does not carry a direct user owner column.

+# Scratchpad — P5-003 Telegram Plugin
+
+## Objective
+
+Implement `@mosaic/telegram-plugin` by matching the established Discord plugin pattern with Telegraf + socket.io-client, add package docs, and pass package typecheck/lint.
+
+## Requirements Source
+
+- docs/PRD.md: Phase 5 remote control / Telegram plugin
+- docs/TASKS.md: P5-003
+- User task brief dated 2026-03-13
+
+## Plan
+
+1. Inspect Discord plugin behavior and package conventions
+2. Add Telegram runtime dependencies if missing
+3. Implement Telegram plugin with matching gateway event flow
+4. Add README usage documentation
+5. Run package typecheck and lint
+6. Run code review and remediate findings
+7. Commit, push, open PR, notify, remove worktree
+
+## TDD Rationale
+
+ASSUMPTION: No existing telegram package test harness or fixture coverage makes package-level TDD
+disproportionate for this plugin scaffold task. Validation will rely on typecheck, lint, and
+manual structural parity with the Discord plugin.
+
+## Risks
+
+- Telegram API typings may differ from Discord’s event shapes and require narrower guards.
+- Socket event payloads may already include `role` in shared gateway expectations.
+
+## Progress Log
+
+- 2026-03-13: Loaded Mosaic/global/repo guidance, mission files, Discord reference implementation, and Telegram package scaffold.
+- 2026-03-13: Added `telegraf` and `socket.io-client` to `@mosaic/telegram-plugin`.
+- 2026-03-13: Implemented Telegram message forwarding, gateway streaming accumulation, response chunking, and package README.
+
+## Verification Evidence
+
+- `pnpm --filter @mosaic/telegram-plugin typecheck` → pass
+- `pnpm --filter @mosaic/telegram-plugin lint` → pass
+- `pnpm typecheck` → pass
+- `pnpm lint` → pass
+
+## Review
+
+- Automated uncommitted review wrapper was invoked for the current delta.
+- Manual review completed against Discord parity, gateway event contracts, and package docs; no additional blockers found.

+# P5-004 Scratchpad
+
+- Objective: Add optional Authentik OIDC SSO adapter via Better Auth genericOAuth.
+- Task ref: P5-004
+- Issue ref: #96
+- Plan:
+  1. Inspect auth/gateway surfaces and Better Auth plugin shape.
+  2. Add failing coverage for auth config/startup validation where feasible.
+  3. Implement adapter, docs, and warnings.
+  4. Run targeted typechecks, lint, and review.
+
+- TDD note: no low-friction auth plugin or bootstrap-env test seam exists for `packages/auth/src/auth.ts` or `apps/gateway/src/main.ts`. This change is configuration-oriented and does not alter an existing behavioral contract with a current test harness. I skipped new tests for this pass and relied on exact typecheck/lint/test commands plus manual review.
+
+- Changes:
+  1. Added conditional Better Auth `genericOAuth` plugin registration for the `authentik` provider in `packages/auth/src/auth.ts`.
+  2. Added a soft startup warning in `apps/gateway/src/main.ts` for incomplete Authentik env configuration.
+  3. Added `docs/plans/authentik-sso-setup.md` with env, redirect URI, and test-flow guidance.
+  4. Confirmed `packages/auth/src/index.ts` already exports `AuthConfig`; no change required there.
+
+- Verification:
+  1. `pnpm --filter @mosaic/db build`
+  2. `pnpm --filter @mosaic/auth typecheck`
+  3. `pnpm --filter @mosaic/gateway typecheck`
+  4. `pnpm lint`
+  5. `pnpm format:check`
+  6. `pnpm --filter @mosaic/auth test`
+  7. `pnpm --filter @mosaic/gateway test`
+
+- Results:
+  1. `@mosaic/auth` typecheck passed after replacing the non-existent `enabled` field with conditional plugin registration.
+  2. `@mosaic/gateway` typecheck passed.
+  3. Repo lint passed.
+  4. Prettier check passed after formatting `apps/gateway/src/main.ts`.
+  5. `@mosaic/auth` tests reported `No test files found, exiting with code 0`.
+  6. `@mosaic/gateway` tests passed: `3` files, `20` tests.
+
+- Review:
+  1. Manual review of the diff found no blocker issues.
+  2. External `codex-code-review.sh --uncommitted` was attempted but did not return a usable verdict in-session; no automated review findings were available from that run.
+
+- Situational evidence:
+  1. Provider activation is env-gated by `AUTHENTIK_CLIENT_ID`.
+  2. Misconfigured optional SSO surfaces a warning instead of crashing gateway startup.
+  3. Setup doc records the expected redirect path: `{BETTER_AUTH_URL}/api/auth/callback/authentik`.

+# Task Ownership Gap Fix Scratchpad
+
+## Metadata
+
+- Date: 2026-03-13
+- Worktree: `/home/jwoltje/src/mosaic-mono-v1-worktrees/fix-task-ownership`
+- Branch: `fix/task-mission-ownership`
+- Scope: Fix ownership checks in TasksController/MissionsController and extend gateway ownership tests
+- Related tracker: worker task only; `docs/TASKS.md` is orchestrator-owned and left unchanged
+- Budget assumption: no explicit token cap; keep scope limited to requested gateway permission fixes
+
+## Objective
+
+Close ownership gaps so task listing/creation and mission creation enforce project/mission ownership and reject cross-user access.
+
+## Acceptance Criteria
+
+1. TasksController `list()` enforces ownership for `projectId` and `missionId`, and does not return cross-user data when neither filter is provided.
+2. TasksController `create()` rejects unowned `projectId` and `missionId` references.
+3. MissionsController `create()` rejects unowned `projectId` references.
+4. Gateway ownership tests cover forbidden task creation and forbidden task listing by unowned project.
+
+## Plan
+
+1. Inspect current controller and ownership test patterns.
+2. Add failing permission tests first.
+3. Patch controller methods with existing ownership helpers.
+4. Run targeted gateway tests, then gateway typecheck/lint/full test.
+5. Perform independent review, record evidence, then complete the requested git/PR workflow.
+
+## TDD Notes
+
+- Required: yes. This is auth/permission logic and a bugfix.
+- Strategy: add failing tests in `resource-ownership.test.ts`, verify red, then implement minimal controller changes.
+
+## Verification Log
+
+- `pnpm --filter @mosaic/gateway test -- src/__tests__/resource-ownership.test.ts`
+  - Red: failed with 2 expected permission-path failures before controller changes.
+  - Green: passed after wiring ownership checks and adding owned-task filtering coverage.
+- `pnpm --filter @mosaic/gateway typecheck`
+  - Pass on 2026-03-13 after fixing parameter ordering and mission project nullability.
+- `pnpm --filter @mosaic/gateway lint`
+  - Pass on 2026-03-13.
+- `pnpm --filter @mosaic/gateway test`
+  - Pass on 2026-03-13 with 3 test files and 23 tests passing.
+- `pnpm format:check`
+  - Pass on 2026-03-13.
+
+## Review Log
+
+- Manual review: checked for auth regressions, cross-user list leakage, and dashboard behavior impact; kept unfiltered task list functional by filtering to owned projects/missions instead of returning an empty list.
+- Automated review: `~/.config/mosaic/tools/codex/codex-code-review.sh --uncommitted` running/re-run for independent review evidence.
+
+## Risks / Blockers
+
+- Repository-wide Mosaic instructions require merge/issue closure, but the user explicitly instructed PR-only and no merge; follow the user instruction.
+- `docs/TASKS.md` is orchestrator-owned and will not be edited from this worker task.

+# @mosaic/telegram-plugin
+
+`@mosaic/telegram-plugin` connects a Telegram bot to the Mosaic gateway chat namespace so Telegram chats can participate in the same conversation flow as the web, TUI, and Discord channels.
+
+## Required Environment Variables
+
+- `TELEGRAM_BOT_TOKEN`: Bot token issued by BotFather
+- `TELEGRAM_GATEWAY_URL`: Base URL for the Mosaic gateway, for example `http://localhost:3000`
+
+## What It Does
+
+- Launches a Telegram bot with `telegraf`
+- Connects to `${TELEGRAM_GATEWAY_URL}/chat` with `socket.io-client`
+- Maps Telegram `chat.id` values to Mosaic `conversationId` values
+- Forwards inbound Telegram text messages to the gateway as user messages
+- Buffers `agent:start` / `agent:text` / `agent:end` socket events and sends the completed response back to the Telegram chat
+
+## Getting a Bot Token
+
+1. Open Telegram and start a chat with `@BotFather`
+2. Run `/newbot`
+3. Follow the prompts to name the bot and choose a username
+4. Copy the generated token and assign it to `TELEGRAM_BOT_TOKEN`
