-# 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**
-

-- 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.

-# Code Review Report — Gateway Security Hardening
-
-## Scope Reviewed
-
-- `apps/gateway/src/chat/chat.gateway-auth.ts`
-- `apps/gateway/src/chat/chat.gateway.ts`
-- `apps/gateway/src/conversations/conversations.dto.ts`
-- `apps/gateway/src/chat/__tests__/chat-security.test.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.

-# 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
-
-- `pnpm --filter @mosaic/gateway test -- src/chat/__tests__/chat-security.test.ts src/__tests__/resource-ownership.test.ts`
-  - Red: failed on socket session reshaping and DTO role/length mismatches.
-  - Green: passed with 3 test files and 20 tests passing.
-- `pnpm typecheck`
-  - Pass on 2026-03-13 with 18/18 package typecheck tasks successful.
-- `pnpm lint`
-  - Pass on 2026-03-13 with 18/18 package lint tasks successful.
-- `pnpm format:check`
-  - Pass on 2026-03-13 with `All matched files use Prettier code style!`
-
-## 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.
