+# Mosaic Stack
+
+Self-hosted, multi-user AI agent platform. One config, every runtime, same standards.
+
+Mosaic gives you a unified launcher for Claude Code, Codex, OpenCode, and Pi — injecting consistent system prompts, guardrails, skills, and mission context into every session. A NestJS gateway provides the API surface, a Next.js dashboard gives you the UI, and a plugin system connects Discord, Telegram, and more.
+
+## Quick Install
+
+```bash
+bash <(curl -fsSL https://git.mosaicstack.dev/mosaic/mosaic-stack/raw/branch/main/tools/install.sh)
+```
+
+This installs both components:
+
+| Component       | What                                                  | Where                |
+| --------------- | ----------------------------------------------------- | -------------------- |
+| **Framework**   | Bash launcher, guides, runtime configs, tools, skills | `~/.config/mosaic/`  |
+| **@mosaic/cli** | TUI, gateway client, wizard, auto-updater             | `~/.npm-global/bin/` |
+
+After install, set up your agent identity:
+
+```bash
+mosaic init          # Interactive wizard
+```
+
+### Requirements
+
+- Node.js ≥ 20
+- npm (for global @mosaic/cli install)
+- One or more runtimes: [Claude Code](https://docs.anthropic.com/en/docs/claude-code), [Codex](https://github.com/openai/codex), [OpenCode](https://opencode.ai), or [Pi](https://github.com/mariozechner/pi-coding-agent)
+
+## Usage
+
+### Launching Agent Sessions
+
+```bash
+mosaic pi                    # Launch Pi with Mosaic injection
+mosaic claude                # Launch Claude Code with Mosaic injection
+mosaic codex                 # Launch Codex with Mosaic injection
+mosaic opencode              # Launch OpenCode with Mosaic injection
+
+mosaic yolo claude           # Claude with dangerous-permissions mode
+mosaic yolo pi               # Pi in yolo mode
+```
+
+The launcher verifies your config, checks for `SOUL.md`, injects your `AGENTS.md` standards into the runtime, and forwards all arguments.
+
+### TUI & Gateway
+
+```bash
+mosaic tui                   # Interactive TUI connected to the gateway
+mosaic login                 # Authenticate with a gateway instance
+mosaic sessions list         # List active agent sessions
+```
+
+### Management
+
+```bash
+mosaic doctor                # Health audit — detect drift and missing files
+mosaic sync                  # Sync skills from canonical source
+mosaic update                # Check for and install CLI updates
+mosaic wizard                # Full guided setup wizard
+mosaic bootstrap <path>      # Bootstrap a repo with Mosaic standards
+mosaic coord init            # Initialize a new orchestration mission
+mosaic prdy init             # Create a PRD via guided session
+```
+
+## Development
+
+### Prerequisites
+
+- Node.js ≥ 20
+- pnpm 10.6+
+- Docker & Docker Compose
+
+### Setup
+
+```bash
+git clone git@git.mosaicstack.dev:mosaic/mosaic-stack.git
+cd mosaic-stack
+
+# Start infrastructure (Postgres, Valkey, Jaeger)
+docker compose up -d
+
+# Install dependencies
+pnpm install
+
+# Run migrations
+pnpm --filter @mosaic/db run db:migrate
+
+# Start all services in dev mode
+pnpm dev
+```
+
+### Infrastructure
+
+Docker Compose provides:
+
+| Service               | Port      | Purpose                |
+| --------------------- | --------- | ---------------------- |
+| PostgreSQL (pgvector) | 5433      | Primary database       |
+| Valkey                | 6380      | Task queue + caching   |
+| Jaeger                | 16686     | Distributed tracing UI |
+| OTEL Collector        | 4317/4318 | Telemetry ingestion    |
+
+### Quality Gates
+
+```bash
+pnpm typecheck               # TypeScript type checking (all packages)
+pnpm lint                    # ESLint (all packages)
+pnpm test                    # Vitest (all packages)
+pnpm format:check            # Prettier check
+pnpm format                  # Prettier auto-fix
+```
+
+### CI
+
+Woodpecker CI runs on every push:
+
+- `pnpm install --frozen-lockfile`
+- Database migration against a fresh Postgres
+- `pnpm test` (Turbo-orchestrated across all packages)
+
+npm packages are published to the Gitea package registry on main merges.

+
+### Key Design Decisions
+
+- **Gateway is the single API surface** — all clients (TUI, web, Discord, Telegram) connect through it
+- **ESM everywhere** — `"type": "module"`, `.js` extensions in imports, NodeNext resolution
+- **Socket.IO typed events** — defined in `@mosaic/types`, enforced at compile time
+- **OTEL auto-instrumentation** — loads before NestJS bootstrap
+- **Explicit `@Inject()` decorators** — required since tsx/esbuild doesn't emit decorator metadata
+
+### Framework (`~/.config/mosaic/`)
+
+The framework is the bash-based standards layer installed to every developer machine:
+
+```
+~/.config/mosaic/
+├── AGENTS.md              ← Central standards (loaded into every runtime)
+├── SOUL.md                ← Agent identity (name, style, guardrails)
+├── USER.md                ← User profile (name, timezone, preferences)
+├── TOOLS.md               ← Machine-level tool reference
+├── bin/mosaic             ← Unified launcher (claude, codex, opencode, pi, yolo)
+├── guides/                ← E2E delivery, orchestrator protocol, PRD, etc.
+├── runtime/               ← Per-runtime configs (claude/, codex/, opencode/, pi/)
+├── skills/                ← Universal skills (synced from agent-skills repo)
+├── tools/                 ← Tool suites (orchestrator, git, quality, prdy, etc.)
+└── memory/                ← Persistent agent memory (preserved across upgrades)
+```
+
+### Forge Pipeline
+
+Forge is a multi-stage AI pipeline for autonomous feature delivery:
+
+```
+Intake → Discovery → Board Review → Planning (3 stages) → Coding → Review → Remediation → Test → Deploy
+```
+
+Each stage has a dispatch mode (`exec` for research/review, `yolo` for coding), quality gates, and timeouts. The board review uses multiple AI personas (CEO, CTO, CFO, COO + specialists) to evaluate briefs before committing resources.
+
+## Upgrading
+
+Run the installer again — it handles upgrades automatically:
+
+```bash
+bash <(curl -fsSL https://git.mosaicstack.dev/mosaic/mosaic-stack/raw/branch/main/tools/install.sh)
+```
+
+Or use the CLI:
+
+```bash
+mosaic update                # Check + install CLI updates
+mosaic update --check        # Check only, don't install
+```
+
+The CLI also performs a background update check on every invocation (cached for 1 hour).
+
+### Installer Flags
+
+```bash
+bash tools/install.sh --check        # Version check only
+bash tools/install.sh --framework    # Framework only (skip npm CLI)
+bash tools/install.sh --cli          # npm CLI only (skip framework)
+bash tools/install.sh --ref v1.0     # Install from a specific git ref
+```
+
+## Contributing
+
+```bash
+# Create a feature branch
+git checkout -b feat/my-feature
+
+# Make changes, then verify
+pnpm typecheck && pnpm lint && pnpm test && pnpm format:check
+
+# Commit (husky runs lint-staged automatically)
+git commit -m "feat: description of change"
+
+# Push and create PR
+git push -u origin feat/my-feature
+```
+
+DTOs go in `*.dto.ts` files at module boundaries. Scratchpads (`docs/scratchpads/`) are mandatory for non-trivial tasks. See `AGENTS.md` for the full standards reference.

+# Brief: Monorepo Consolidation — mosaic/stack → mosaic/mosaic-stack
+
+## Source
+
+Architecture consolidation — merge the mosaic/stack repo (Forge pipeline, MACP protocol, framework tools) into mosaic/mosaic-stack (Harness Foundation platform). Two repos doing related work that need to converge.
+
+## Context
+
+**mosaic/stack** (OLD) contains:
+
+- Forge progressive refinement pipeline (stages, agents, personas, rails, debate protocol, brief classification)
+- MACP protocol (JSON schemas, deterministic Python controller, dispatcher, event system, gate runner)
+- Credential resolver (Python — OC config, mosaic files, ambient env, JSON5 parser)
+- OC framework plugin (injects Mosaic rails into all agent sessions)
+- Profiles (runtime-neutral context packs for tech stacks and domains)
+- Stage adapter (Forge→MACP bridge)
+- Board tasks (multi-agent board evaluation)
+- OpenBrain specialist memory (learning capture/recall)
+- 17 guides, 5 universal skills
+
+**mosaic/mosaic-stack** (NEW) contains:
+
+- Harness Foundation platform (NestJS gateway, Next.js web, Drizzle ORM, Pi SDK runtime)
+- 5 provider adapters, task classifier, routing rules, model capability matrix
+- MACP OC plugin (ACP runtime backend with Pi bridge)
+- TS coord package (mission runner, tasks file manager, status tracker — 1635 lines)
+- BullMQ job queue, OTEL telemetry, channel plugins (Discord, Telegram)
+- CLI with TUI, 65/65 tasks done, v0.2.0
+
+**Decision:** NEW repo is the base. All unique work from OLD gets ported into NEW as packages.
+
+## Scope
+
+### Work Package 1: Forge Pipeline Package (`packages/forge`)
+
+Port the entire Forge progressive refinement pipeline as a TypeScript package.
+
+**From OLD:**
+
+- `forge/pipeline/stages/*.md` — 11 stage definitions
+- `forge/pipeline/agents/{board,generalists,specialists,cross-cutting}/*.md` — all persona definitions
+- `forge/pipeline/rails/*.md` — debate protocol, dynamic composition, worker rails
+- `forge/pipeline/gates/` — gate reviewer definitions
+- `forge/pipeline/orchestrator/run-structure.md` — file-based observability spec
+- `forge/templates/` — brief and PRD templates
+- `forge/pipeline/orchestrator/board_tasks.py` → rewrite in TS
+- `forge/pipeline/orchestrator/stage_adapter.py` → rewrite in TS
+- `forge/pipeline/orchestrator/pipeline_runner.py` → rewrite in TS
+- `forge/forge` CLI (Python) → rewrite in TS, integrate with `packages/cli`
+
+**Package structure:**
+
+```
+packages/forge/
+├── src/
+│   ├── index.ts              # Public API
+│   ├── pipeline-runner.ts    # Orchestrates full pipeline run
+│   ├── stage-adapter.ts      # Maps stages to MACP/coord tasks
+│   ├── board-tasks.ts        # Multi-agent board evaluation task generator
+│   ├── brief-classifier.ts   # strategic/technical/hotfix classification
+│   ├── types.ts              # Stage specs, run manifest, gate results
+│   └── constants.ts          # Stage sequence, timeouts, labels
+├── pipeline/
+│   ├── stages/               # .md stage definitions (copied)
+│   ├── agents/               # .md persona definitions (copied)
+│   │   ├── board/
+│   │   ├── cross-cutting/
+│   │   ├── generalists/
+│   │   └── specialists/
+│   │       ├── language/
+│   │       └── domain/
+│   ├── rails/                # .md rails (copied)
+│   ├── gates/                # .md gate definitions (copied)
+│   └── templates/            # brief + PRD templates (copied)
+└── package.json
+```
+
+**Key design decisions:**
+
+- Pipeline markdown assets are runtime data, not compiled — ship as-is in the package
+- `pipeline-runner.ts` calls into `packages/coord` for task execution (not a separate controller)
+- Stage adapter generates coord-compatible tasks, not MACP JSON directly
+- Board tasks use `depends_on_policy: "all_terminal"` for synthesis
+- Per-stage timeouts from `STAGE_TIMEOUTS` map
+- Brief classifier supports CLI flag, YAML frontmatter, and keyword auto-detection
+- Run output goes to project-scoped `.forge/runs/{run-id}/` (not inside the Forge package)
+
+**Persona override system (new):**
+
+- Base personas ship with the package (read-only)
+- Project-level overrides in `.forge/personas/{role}.md` extend (not replace) base personas
+- Board composition configurable via `.forge/config.yaml`:
+  ```yaml
+  board:
+    additional_members:
+      - compliance-officer.md
+    skip_members: []
+  specialists:
+    always_include:
+      - proxmox-expert
+  ```
+- OpenBrain integration for cross-run specialist memory (when enabled)
+
+### Work Package 2: MACP Protocol Package (`packages/macp`)
+
+Port the MACP protocol layer, event system, and gate runner as a TypeScript package.
+
+**From OLD:**
+
+- `tools/macp/protocol/task.schema.json` — task JSON schema
+- `tools/macp/protocol/` — event schemas
+- `tools/macp/controller/gate_runner.py` → rewrite in TS as `gate-runner.ts`
+- `tools/macp/events/` — event watcher, webhook adapter, Discord formatter → rewrite in TS
+- `tools/macp/dispatcher/credential_resolver.py` → rewrite in TS as `credential-resolver.ts`
+- `tools/macp/memory/learning_capture.py` + `learning_recall.py` → rewrite in TS
+
+**Package structure:**
+
+```
+packages/macp/
+├── src/
+│   ├── index.ts                # Public API
+│   ├── types.ts                # Task, event, result, gate types
+│   ├── schemas/                # JSON schemas (copied)
+│   ├── gate-runner.ts          # Mechanical + AI review quality gates
+│   ├── credential-resolver.ts  # Provider credential resolution (mosaic files, OC config, ambient)
+│   ├── event-emitter.ts        # Append events to ndjson, structured event types
+│   ├── event-watcher.ts        # Poll events.ndjson with cursor persistence
+│   ├── webhook-adapter.ts      # POST events to configurable URL
+│   ├── discord-formatter.ts    # Human-readable event messages
+│   └── learning.ts             # OpenBrain capture + recall
+└── package.json
+```
+
+**Integration with existing packages:**
+
+- `packages/coord` uses `packages/macp` for event emission, gate running, and credential resolution
+- `plugins/macp` uses `packages/macp` for protocol types and credential resolution
+- `packages/forge` uses `packages/macp` gate types for stage gates
+
+### Work Package 3: OC Framework Plugin (`plugins/mosaic-framework`)
+
+Port the OC framework plugin that injects Mosaic rails into all agent sessions.
+
+**From OLD:**
+
+- `oc-plugins/mosaic-framework/index.ts` — `before_agent_start` + `subagent_spawning` hooks
+- `oc-plugins/mosaic-framework/openclaw.plugin.json`
+
+**Structure:**
+
+```
+plugins/mosaic-framework/
+├── src/
+│   └── index.ts    # Plugin hooks
+└── package.json
+```
+
+**This is separate from `plugins/macp`:**
+
+- `mosaic-framework` = injects Mosaic rails/contracts into every OC session (passive enforcement)
+- `macp` = provides an ACP runtime backend for MACP task execution (active runtime)
+
+### Work Package 4: Profiles + Guides + Skills
+
+Port reference content as a documentation/config package or top-level directories.
+
+**From OLD:**
+
+- `profiles/domains/*.json` — HIPAA, fintech, crypto context packs
+- `profiles/tech-stacks/*.json` — NestJS, Next.js, FastAPI, React conventions
+- `profiles/workflows/*.json` — API development, frontend component, testing workflows
+- `guides/*.md` — 17 guides (auth, backend, QA, orchestrator, PRD, etc.)
+- `skills-universal/` — jarvis, macp, mosaic-standards, prd, setup-cicd skills
+
+**Destination:**
+
+```
+profiles/           # Top-level (same as OLD)
+guides/             # Top-level (same as OLD)
+skills/             # Top-level (renamed from skills-universal)
+```
+
+These are runtime-neutral assets consumed by any agent or profile loader — they don't belong in a compiled package.
+
+## Out of Scope
+
+- Rewriting the NestJS orchestrator app from OLD (`apps/orchestrator/`) — its functionality is subsumed by `packages/coord` + `apps/gateway`
+- Porting the FastAPI coordinator from OLD (`apps/coordinator/`) — its functionality (webhook receiver, issue parser, quality orchestrator) is handled by `packages/coord` + `apps/gateway` in the new architecture
+- Porting the Prisma schema or OLD's `apps/api` — Drizzle migration is complete
+- Old Docker Compose configs (Traefik, Matrix, OpenBao) — NEW has its own infra setup
+
+## Success Criteria
+
+1. `packages/forge` exists with all 11 stage definitions, all persona markdowns, all rails, and TS implementations of pipeline-runner, stage-adapter, board-tasks, and brief-classifier
+2. `packages/macp` exists with gate-runner, credential-resolver, event system, and learning capture/recall — all in TypeScript
+3. `plugins/mosaic-framework` exists and registers OC hooks for rails injection
+4. Profiles, guides, and skills are present at top-level
+5. `packages/forge` integrates with `packages/coord` for task execution
+6. `packages/macp` credential-resolver is used by `plugins/macp` Pi bridge
+7. All existing tests pass (no regressions)
+8. New packages have test coverage ≥85%
+9. `pnpm lint && pnpm typecheck && pnpm build` passes
+10. `.forge/runs/` project-scoped output directory works for at least one test run
+
+## Technical Constraints
+
+- All new code is ESM with NodeNext module resolution
+- No Python in the new repo — everything rewrites to TypeScript
+- Pipeline markdown assets (stages, personas, rails) are shipped as package data, not compiled
+- Credential resolver must support: mosaic credential files, OC config (JSON5), ambient environment — same resolution order as the Python version
+- Must preserve `depends_on_policy` semantics (all, any, all_terminal)
+- Per-stage timeouts must be preserved
+- JSON5 stripping must use the placeholder-extraction approach (not naive regex on string content)
+
+## Estimated Complexity
+
+High — crosses 4 work packages with protocol porting, TS rewrites, and integration wiring. Each work package is independently shippable.
+
+**Suggested execution order:**
+
+1. WP4 (profiles/guides/skills) — pure copy, no code, fast win
+2. WP2 (packages/macp) — protocol foundation, needed by WP1 and WP3
+3. WP1 (packages/forge) — the big one, depends on WP2
+4. WP3 (plugins/mosaic-framework) — OC integration, can parallel with WP1
+
+## Dependencies
+
+- `packages/coord` must be stable (it is — WP1 integrates with it)
+- `plugins/macp` must be stable (it is — WP2 provides types/credentials to it)
+- Pi SDK (`@mariozechner/pi-agent-core`) already in the dependency tree

 ## Success Criteria
 
-- [x] AC-1: Core chat flow — login, send message, streamed response, conversations persist
-- [x] AC-2: TUI integration — `mosaic tui` connects to gateway, same context as web
-- [x] AC-3: Discord remote control — bot responds, routes through gateway, threads work
-- [x] AC-4: Gateway orchestration — multi-provider routing, fallback, concurrent sessions
-- [x] AC-5: Task & project management — CRUD, kanban, mission tracking, brain MCP tools
-- [x] AC-6: Memory system — auto-capture, semantic search, preferences, log summarization
-- [x] AC-7: Auth & RBAC — email/password, Authentik SSO, role enforcement
-- [x] AC-8: Multi-provider LLM — 3+ providers routing correctly
-- [x] AC-9: MCP — gateway MCP endpoint, brain + queue tools via MCP
-- [x] AC-10: Deployment — `docker compose up` from clean state, CLI on bare metal
-- [x] AC-11: @mosaic/\* packages — all 7 migrated packages build, test, integrate
+- [x] AC-1: Send messages in TUI → restart TUI → resume conversation → agent has full history and context
+- [x] AC-2: Route a coding task to Claude Opus 4.6, a simple question to Haiku, a summarization to GLM-5 — all via granular routing rules
+- [x] AC-3: Two users exist, User A's memory searches never return User B's data
+- [x] AC-4: `/model claude-sonnet-4-6` in TUI switches the active model for subsequent messages
+- [x] AC-5: `/agent coding-agent` in TUI switches to a different agent with different system prompt and tools
+- [x] AC-6: BullMQ jobs execute on schedule, failures retry with backoff, admin can inspect via `/api/admin/jobs`
+- [x] AC-7: Channel protocol document exists with Matrix integration points defined, reviewed, and approved
+- [x] AC-8: Embeddings run on Ollama local models (no external API dependency for vector operations)
+- [x] AC-9: All five providers (Anthropic, OpenAI, OpenRouter, Z.ai, Ollama) connect, list models, and complete chat requests
+- [x] AC-10: Routing transparency — TUI displays which model was selected and the routing reason for each response

+# PRD: Harness Foundation — Phase 9
+
+## Metadata
+
+- **Owner:** Jason Woltje
+- **Date:** 2026-03-21
+- **Status:** completed
+- **Phase:** 9 (post-MVP)
+- **Version Target:** v0.2.0
+- **Agent Harness:** [Pi SDK](https://github.com/badlogic/pi-mono)
+- **Best-Guess Mode:** true
+- **Repo:** `git.mosaicstack.dev/mosaic/mosaic-stack`
+
+---
+
+## Problem Statement
+
+Mosaic Stack v0.1.0 delivered a functional skeleton — gateway boots, TUI connects, single-agent chat streams, basic auth works. But the system is not usable as a daily-driver harness:
+
+1. **Chat messages are fire-and-forget.** The WebSocket gateway never calls ConversationsRepo. Context is lost on disconnect. Conversations can't be resumed with history. Cross-interface continuity (TUI → WebUI → Matrix) is impossible.
+
+2. **Single provider (Ollama) with local models only.** No access to frontier models (Claude Opus 4.6, Codex gpt-5.4, GLM-5). The routing engine exists but has never been tested with real providers.
+
+3. **No task-aware agent routing.** A coding task and a summarization task route to the same agent with the same model. There is no mechanism to match tasks to agents by capability, cost tier, or specialization.
+
+4. **Memory is not user-scoped.** Insight vector search returns all users' data. Deploying multi-user is a security violation.
+
+5. **Agent configs exist in DB but are ignored.** Stored system prompts, model preferences, and tool allowlists don't apply to sessions. The `/model` and `/agent` slash commands are stubbed.
+
+6. **No job queue.** Background processing (summarization, GC, tier management) runs on fragile cron. No retry, no monitoring, no async task dispatch foundation for future agent orchestration.
+
+7. **Plugin system is hollow.** Zero implementations. No defined message protocol. Blocks all remote interfaces (Matrix, Discord, Telegram) planned for Phase 10+.
+
+**What this phase solves:** Transform Mosaic from a demo into a real multi-provider, task-routing AI harness that persists everything, routes intelligently, and is architecturally ready for multi-agent and remote control.
+
+---
+
+## Objectives
+
+1. **Persistent conversations** — Every message saved, every conversation resumable, full context available across interfaces
+2. **Multi-provider LLM access** — Anthropic, OpenAI, OpenRouter, Z.ai, Ollama with proper auth flows
+3. **Task-aware agent routing** — Granular routing rules that match tasks to the right agent + model by capability, cost, and domain
+4. **Security isolation** — All data queries user-scoped, ready for multi-user deployment
+5. **Session hardening** — Agent configs apply, model/agent switching works mid-session
+6. **Reliable background processing** — BullMQ job queue replaces fragile cron
+7. **Channel protocol design** — Architecture for Matrix and remote interfaces, built into the foundation now
+
+---
+
+## Scope
+
+### In Scope
+
+1. Conversation persistence — wire ChatGateway to ConversationsRepo, context loading on resume
+2. Multi-provider integration — Anthropic, OpenAI, OpenRouter, Z.ai, Ollama with auth flows
+3. Task-aware agent routing — granular routing rules with task classification and fallback chains
+4. Security isolation — user-scoped queries on all data paths (memory, conversations, agents)
+5. Agent session hardening — configs apply, model/agent switching, session resume
+6. Job queue — BullMQ replacing cron for background processing
+7. Channel protocol design — architecture document for Matrix and remote interfaces
+8. Embedding migration — Ollama-local embeddings replacing OpenAI dependency
+
+### Out of Scope
+
+1. Matrix homeserver deployment + appservice (Phase 10)
+2. Multi-agent orchestration / supervisor-worker pattern (Phase 10+)
+3. WebUI rebuild (future)
+4. Self-managing memory — compaction, merge, forget (future)
+5. Team workspace isolation (future)
+6. Remote channel plugins — WhatsApp, Discord, Telegram (Phase 10+, via Matrix)
+7. Fine-grained RBAC — project/agent/team roles (future)
+8. Agent-to-agent communication (Phase 10+)
+
+## User/Stakeholder Requirements
+
+1. As a user, I can resume a conversation after closing the TUI and the agent remembers the full context
+2. As a user, I can use frontier models (Claude Opus 4.6, Codex gpt-5.4) without manual provider configuration
+3. As a user, the system automatically selects the best model for my task (coding → powerful model, simple question → cheap model)
+4. As a user, I can override the automatic model selection with `/model <name>` at any time
+5. As a user, I can switch between specialized agents mid-session with `/agent <name>`
+6. As an admin, I can define routing rules that control which models handle which task types
+7. As an admin, I can monitor background job health and retry failed jobs
+8. As a user, my conversations, memories, and preferences are invisible to other users
+
+## Functional Requirements
+
+1. FR-1: ChatGateway persists every message (user, assistant, tool call, thinking) to the conversations/messages tables
+2. FR-2: On session resume with an existing conversationId, message history is loaded from DB and injected into the agent session context
+3. FR-3: When conversation history exceeds 80% of the model's context window, older messages are summarized and prepended as a context checkpoint
+4. FR-4: Five LLM providers are registered with the gateway: Anthropic (Claude Sonnet 4.6, Opus 4.6, Haiku 4.5), OpenAI (Codex gpt-5.4), OpenRouter (dynamic model list), Z.ai (GLM-5), Ollama (local models)
+5. FR-5: Each provider supports API key auth; Anthropic and OpenAI additionally support OAuth (URL-display + callback pattern)
+6. FR-6: Provider credentials are stored per-user in the DB (encrypted), not in environment variables
+7. FR-7: A routing engine classifies each user message by taskType, complexity, domain, and required capabilities, then selects the optimal provider/model via priority-ordered rules
+8. FR-8: Default routing rules are seeded on first run; admins can customize system-wide rules; users can set per-session overrides
+9. FR-9: Routing decisions are transparent — the TUI shows which model was selected and why
+10. FR-10: Agent configs (system prompt, default model, tool allowlist, skills) stored in DB are applied when creating agent sessions
+11. FR-11: `/model <name>` switches the active model for subsequent messages in the current session
+12. FR-12: `/agent <name>` switches to a different agent config, loading its system prompt, tools, and default model
+13. FR-13: All memory queries (insight vector search, preferences) filter by userId
+14. FR-14: BullMQ handles background jobs (summarization, GC, tier management) with retry, backoff, and monitoring
+15. FR-15: Embeddings are served locally via Ollama (nomic-embed-text or mxbai-embed-large) with no external API dependency
+
+## Non-Functional Requirements
+
+1. **Security:** All data queries include userId filter. Provider credentials encrypted at rest. No cross-user data leakage. OAuth tokens stored securely with refresh handling.
+2. **Performance:** Message persistence adds <50ms to message relay latency. Routing classification <100ms per message. Provider health checks run on configurable interval (default 60s) without blocking requests.
+3. **Reliability:** BullMQ jobs retry with exponential backoff (3 attempts default). Provider failover: if primary provider is unhealthy, fallback chain activates automatically. Conversation context survives TUI restart.
+4. **Observability:** Routing decisions logged with classification details. Job execution logged to agent_logs. Provider health status exposed via `/api/providers/health`. Session metrics (tokens, model switches, duration) persisted in DB.
+
+## Acceptance Criteria
+
+- [ ] AC-1: Send messages in TUI → restart TUI → resume conversation → agent has full history and context
+- [ ] AC-2: Route a coding task to Claude Opus 4.6, a simple question to Haiku, a summarization to GLM-5 — all via granular routing rules
+- [ ] AC-3: Two users exist, User A's memory searches never return User B's data
+- [ ] AC-4: `/model claude-sonnet-4-6` in TUI switches the active model for subsequent messages
+- [ ] AC-5: `/agent coding-agent` in TUI switches to a different agent with different system prompt and tools
+- [ ] AC-6: BullMQ jobs execute on schedule, failures retry with backoff, admin can inspect via `/api/admin/jobs`
+- [ ] AC-7: Channel protocol document exists with Matrix integration points defined, reviewed, and approved
+- [ ] AC-8: Embeddings run on Ollama local models (no external API dependency for vector operations)
+- [ ] AC-9: All five providers (Anthropic, OpenAI, OpenRouter, Z.ai, Ollama) connect, list models, and complete chat requests
+- [ ] AC-10: Routing transparency — TUI displays which model was selected and the routing reason for each response
+
+## Testing and Verification Expectations
+
+1. **Baseline checks:** `pnpm typecheck`, `pnpm lint`, `pnpm format:check` — all green before any push
+2. **Unit tests:** Routing engine rules matching, task classifier, provider adapter registration, message persistence
+3. **Integration tests:** Two-user isolation (M2-007), provider round-trip (M3-012), routing end-to-end (M4-013), session resume with context (M1-008)
+4. **Situational tests per milestone:** Each milestone has a verify task that exercises the delivered functionality end-to-end
+5. **Evidence format:** Test output + manual verification notes in scratchpad per milestone

+
+## Assumptions
+
+1. ASSUMPTION: Pi SDK supports custom provider adapters for all target LLM providers. If not, adapters wrap native SDKs behind Pi's interface. **Rationale:** Gateway already uses Pi with Ollama via a custom adapter pattern.
+2. ASSUMPTION: BullMQ is Valkey-compatible. **Rationale:** BullMQ documents Redis 6+ compatibility; Valkey 8 is Redis-compatible.
+3. ASSUMPTION: Ollama can serve embedding models (nomic-embed-text, mxbai-embed-large) with acceptable quality. **Rationale:** Ollama supports embedding endpoints natively.
+4. ASSUMPTION: Anthropic and OpenAI OAuth flows can be handled via URL-display + token callback pattern (same as existing provider auth). **Rationale:** Both providers offer standard OAuth 2.0 flows.
+5. ASSUMPTION: Z.ai GLM-5 uses an API format compatible with OpenAI or has a documented SDK. **Rationale:** Most LLM providers converge on OpenAI-compatible APIs.
+6. ASSUMPTION: The existing Pi SDK session model supports mid-session model switching without destroying session state. If not, we destroy and recreate with conversation history. **Rationale:** Acceptable fallback — context is persisted in DB.
+7. ASSUMPTION: Channel protocol design can be completed without a running Matrix homeserver. **Rationale:** Matrix protocol is well-documented; design is architecture, not integration.

+
+## Milestones
+
+### Milestone 1: Conversation Persistence & Context
+
+**Goal:** Every message persisted. Every conversation resumable with full context.
+
+| Task   | Description                                                                                                  |
+| ------ | ------------------------------------------------------------------------------------------------------------ |

+| M1-002 | Wire agent event relay → ConversationsRepo.addMessage() for assistant responses (text, tool calls, thinking) |
+| M1-003 | Store message metadata: model used, provider, token counts, tool call details, timestamps                    |
+| M1-004 | On session resume (existing conversationId), load message history from DB and inject into Pi session context |
+| M1-005 | Context window management: if history exceeds model context, summarize older messages and prepend summary    |
+| M1-006 | Conversation search: full-text search on messages table via `/api/conversations/search`                      |
+| M1-007 | TUI: `/history` command to display conversation message count and context usage                              |
+| M1-008 | Verify: send messages → kill TUI → resume with `-c <id>` → agent references prior context                    |
+
+### Milestone 2: Security & Isolation
+
+**Goal:** All data queries user-scoped. Safe for multi-user deployment.
+
+| Task   | Description                                                                                                     |

+| M2-005 | Audit ConversationsRepo: verify ownership check on findById, update, delete, addMessage, findMessages           |
+| M2-006 | Audit AgentsRepo: verify `findAccessible()` returns only user's agents + system agents                          |
+| M2-007 | Add integration test: create two users, populate data for each, verify cross-user isolation on every query path |
+| M2-008 | Audit Valkey keys: verify session keys include userId or are not enumerable across users                        |
+
+### Milestone 3: Provider Integration
+
+**Goal:** Five providers operational with proper auth, health checking, and capability metadata.
+
+| Task   | Description                                                                                                                                               |
+| ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| M3-001 | Refactor ProviderService into provider adapter pattern: `IProviderAdapter` interface with `register()`, `listModels()`, `healthCheck()`, `createClient()` |
+| M3-002 | Anthropic adapter: `@anthropic-ai/sdk`, register Claude Sonnet 4.6 + Opus 4.6, OAuth flow (URL display + callback), API key fallback                      |

+| M3-005 | Z.ai GLM adapter: register GLM-5, API key auth, research and implement API format                                                                         |
+| M3-006 | Ollama adapter: refactor existing Ollama integration into adapter pattern, add embedding model support                                                    |
+| M3-007 | Provider health check: periodic probe (configurable interval), status per provider, expose via `/api/providers/health`                                    |
+| M3-008 | Model capability matrix: define per-model metadata (tier, context window, tool support, vision, streaming, embedding capable)                             |
+| M3-009 | Refactor EmbeddingService: replace OpenAI-hardcoded client with provider-agnostic interface, Ollama as default (nomic-embed-text or mxbai-embed-large)    |
+| M3-010 | OAuth token storage: persist provider tokens per user in DB (encrypted), refresh flow                                                                     |

+| M3-012 | Verify: each provider connects, lists models, completes a chat request, handles errors gracefully                                                         |
+
+### Milestone 4: Agent Routing Engine
+
+**Goal:** Granular, rule-based routing that matches tasks to the right agent and model by capability, cost, and domain specialization.
+
+| Task   | Description                                                                                                                                                                                                                                                                                            |
+| ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| M4-001 | Define routing rule schema: `RoutingRule { name, priority, conditions[], action }` stored in DB                                                                                                                                                                                                        |
+| M4-002 | Condition types: `taskType` (coding, research, summarization, conversation, analysis, creative), `complexity` (simple, moderate, complex), `domain` (frontend, backend, devops, docs, general), `costTier` (cheap, standard, premium), `requiredCapabilities` (tools, vision, long-context, reasoning) |
+| M4-003 | Action types: `routeTo { provider, model, agentConfigId?, systemPromptOverride?, toolAllowlist? }`                                                                                                                                                                                                     |
+| M4-004 | Default routing rules (seed data): coding → Opus 4.6, simple Q&A → Sonnet 4.6, summarization → GLM-5, research → Codex gpt-5.4, local/offline → Ollama llama3.2                                                                                                                                        |
+| M4-005 | Task classification: lightweight classifier that infers taskType + complexity from user message (can be rule-based regex/keyword initially, LLM-assisted later)                                                                                                                                        |
+| M4-006 | Routing decision pipeline: classify task → match rules by priority → select best available provider/model → fallback chain if primary unavailable                                                                                                                                                      |

+### Milestone 5: Agent Session Hardening
+
+**Goal:** Agent configs apply to sessions. Model and agent switching work mid-session.
+
+| Task   | Description                                                                                                                                |
+| ------ | ------------------------------------------------------------------------------------------------------------------------------------------ |
+| M5-001 | Wire ChatGateway: on session create, load agent config from DB (system prompt, model, provider, tool allowlist, skills)                    |
+| M5-002 | `/model <name>` command: end-to-end wiring — TUI → socket `command:execute` → gateway switches provider/model → new messages use new model |
+| M5-003 | `/agent <name>` command: switch to different agent config mid-session — loads new system prompt, tools, and default model                  |
+| M5-004 | Session ↔ conversation binding: persist sessionId on conversation record, allow session resume via conversation ID                         |
+| M5-005 | Session info broadcast: on model/agent switch, emit `session:info` with updated provider, model, agent name                                |
+| M5-006 | Agent creation from TUI: `/agent new` command creates agent config via gateway API                                                         |
+| M5-007 | Session metrics: track per-session token usage, model switches, duration — persist in DB                                                   |
+| M5-008 | Verify: start TUI → `/model claude-opus-4-6` → verify response uses Opus → `/agent research-bot` → verify system prompt changes            |
+
+### Milestone 6: Job Queue Foundation
+
+**Goal:** Reliable background processing via BullMQ. Foundation for future agent task orchestration.
+
+| Task   | Description                                                                                                  |
+| ------ | ------------------------------------------------------------------------------------------------------------ |
+| M6-001 | Add BullMQ dependency, configure with Valkey connection                                                      |
+| M6-002 | Create queue service: typed job definitions, worker registration, error handling with exponential backoff    |
+| M6-003 | Migrate summarization cron → BullMQ repeatable job                                                           |
+| M6-004 | Migrate GC (session cleanup) → BullMQ repeatable job                                                         |
+| M6-005 | Migrate tier management (log archival) → BullMQ repeatable job                                               |
+| M6-006 | Admin jobs API: `GET /api/admin/jobs` — list active/completed/failed jobs, retry failed, pause/resume queues |
+| M6-007 | Job event logging: emit job start/complete/fail events to agent_logs for observability                       |
+| M6-008 | Verify: jobs execute on schedule, deliberate failure retries with backoff, admin endpoint shows job history  |
+
+### Milestone 7: Channel Protocol Design
+
+**Goal:** Architecture document defining how remote interfaces (Matrix, Discord, Telegram) will integrate. No code — design only. Built into foundation now so Phase 10+ doesn't require gateway rewrites.
+
+| Task   | Description                                                                                                                                                                                |
+| ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| M7-001 | Define `IChannelAdapter` interface: lifecycle (connect, disconnect, health), message flow (receiveMessage → gateway, sendMessage ← gateway), identity mapping (channel user ↔ Mosaic user) |
+| M7-002 | Define channel message protocol: canonical message format that all adapters translate to/from (content, metadata, attachments, thread context)                                             |
+| M7-003 | Design Matrix integration: appservice registration, room ↔ conversation mapping, space ↔ team mapping, agent ghost users, power levels for human observation                               |
+| M7-004 | Design conversation multiplexing: same conversation accessible from TUI + WebUI + Matrix simultaneously, real-time sync via gateway events                                                 |
+| M7-005 | Design remote auth bridging: how a Matrix/Discord message authenticates to Mosaic (token linking, OAuth bridge, invite-based provisioning)                                                 |
+| M7-006 | Design agent-to-agent communication via Matrix rooms: room per agent pair, human can join to observe, message format for structured agent dialogue                                         |
+| M7-007 | Design multi-user isolation in Matrix: space-per-team, room visibility rules, encryption considerations, admin visibility                                                                  |
+| M7-008 | Publish architecture doc: `docs/architecture/channel-protocol.md` — reviewed and approved before Phase 10                                                                                  |

+## Technical Approach
+
+### Pi SDK Provider Adapter Pattern
+
+The agent layer stays on Pi SDK. Provider diversity is solved at the adapter layer below Pi:
+
+```
+Provider SDKs (@anthropic-ai/sdk, openai, etc.)
+  → IProviderAdapter implementations
+    → ProviderRegistry (Pi SDK compatible)
+      → Agent Session (Pi SDK) — tool loops, streaming, context
+        → AgentService — lifecycle, routing, events
+          → ChatGateway — WebSocket to all interfaces
+```
+
+Adding a provider means implementing `IProviderAdapter`. Everything above stays unchanged.
+
+### Routing Decision Flow
+
+```
+User sends message
+  → Task classifier (regex/keyword, optionally LLM-assisted)
+    → { taskType, complexity, domain, requiredCapabilities }
+  → RoutingEngine.resolve(classification, userOverrides, availableProviders)
+    → Match rules by priority
+    → Check provider health
+    → Apply fallback chain
+    → Return { provider, model, agentConfigId }
+  → AgentService.createOrResumeSession(routingResult)
+    → Session uses selected provider/model
+  → Emit session:info with routing decision explanation
+```
+
+### Embedding Strategy
+
+Replace OpenAI-hardcoded embedding service with provider-agnostic interface:
+
+- **Default:** Ollama serving `nomic-embed-text` (768-dim) or `mxbai-embed-large` (1024-dim)
+- **Fallback:** Any OpenAI-compatible embedding API
+- **Migration:** Update pgvector column dimension if switching from 1536 (OpenAI) to 768/1024 (Ollama models)
+- **No external API dependency** for vector operations in default configuration
+
+### Context Window Management
+
+When conversation history exceeds model context:
+
+1. Calculate token count of full history
+2. If exceeds 80% of model context window, trigger summarization
+3. Summarize oldest N messages into a condensed context block
+4. Prepend summary + keep recent messages within context budget
+5. Store summary as a "context checkpoint" message in DB
+

+| Pi SDK doesn't support custom provider adapters cleanly | High — blocks M3          | Verify in M3-001; fallback: wrap native SDKs and bypass Pi's registry, feeding responses into Pi's session format |
+| BullMQ + Valkey incompatibility                         | Medium — blocks M6        | Test in M6-001 before migrating jobs; fallback: use `bullmq` with `ioredis` directly                              |
+| Embedding dimension migration (1536 → 768/1024)         | Medium — data migration   | Run migration script to re-embed existing insights; or start fresh if insight count is low                        |
+| Z.ai GLM-5 API undocumented                             | Low — blocks one provider | Deprioritize; other 4 providers cover all use cases                                                               |
+| Context window summarization quality                    | Medium — affects UX       | Start with simple truncation; add LLM summarization iteratively                                                   |
+| OAuth flow complexity in TUI (no browser redirect)      | Medium                    | URL-display + clipboard + Valkey poll token pattern (already designed in P8-012)                                  |
+
+### Open Questions
+
+1. What is the Z.ai GLM-5 API format? OpenAI-compatible or custom SDK? (Research in M3-005)
+2. Should routing classification use LLM-assisted classification from the start, or rule-based only? (ASSUMPTION: rule-based first, LLM-assisted later)
+3. What Ollama embedding model provides the best quality/performance tradeoff? (Test nomic-embed-text vs mxbai-embed-large in M3-009)
+4. Should provider credentials be stored in DB per-user, or remain environment-variable based for system-wide providers? (ASSUMPTION: hybrid — env vars for system defaults, DB for per-user overrides)
+

+
+## Milestone / Delivery Intent
+
+1. **Target version:** v0.2.0
+2. **Milestone count:** 7
+3. **Definition of done:** All 10 acceptance criteria verified with evidence, all quality gates green, PRD status updated to `completed`
+4. **Delivery order:** M1 (persistence) → M2 (security) → M3 (providers) → M4 (routing) → M5 (sessions) → M6 (jobs) → M7 (channel design)
+5. **M1 and M2 are prerequisites** — no provider or routing work begins until conversations persist and data is user-scoped

+# Channel Protocol Architecture
+
+**Status:** Draft
+**Authors:** Mosaic Core Team
+**Last Updated:** 2026-03-22
+**Covers:** M7-001 (IChannelAdapter interface), M7-002 (ChannelMessage protocol), M7-003 (Matrix integration design), M7-004 (conversation multiplexing), M7-005 (remote auth bridging), M7-006 (agent-to-agent communication via Matrix), M7-007 (multi-user isolation in Matrix)
+
+---
+
+## Overview
+
+The channel protocol defines a unified abstraction layer between Mosaic's core messaging infrastructure and the external communication channels it supports (Matrix, Discord, Telegram, TUI, WebUI, and future channels).
+
+The protocol consists of two main contracts:
+
+1. `IChannelAdapter` — the interface each channel driver must implement.
+2. `ChannelMessage` — the canonical message format that flows through the system.
+
+All channel-specific translation logic lives inside the adapter implementation. The rest of Mosaic works exclusively with `ChannelMessage` objects.
+
+---
+
+## M7-001: IChannelAdapter Interface
+
+```typescript
+interface IChannelAdapter {
+  /**
+   * Stable, lowercase identifier for this channel (e.g. "matrix", "discord").
+   * Used as a namespace key in registry lookups and log metadata.
+   */
+  readonly name: string;
+
+  /**
+   * Establish a connection to the external channel backend.
+   * Called once at application startup. Must be idempotent (safe to call
+   * when already connected).
+   */
+  connect(): Promise<void>;
+
+  /**
+   * Gracefully disconnect from the channel backend.
+   * Must flush in-flight sends and release resources before resolving.
+   */
+  disconnect(): Promise<void>;
+
+  /**
+   * Return the current health of the adapter connection.
+   * Used by the admin health endpoint and alerting.
+   *
+   * - "connected"    — fully operational
+   * - "degraded"     — partial connectivity (e.g. read-only, rate-limited)
+   * - "disconnected" — no connection to channel backend
+   */
+  health(): Promise<{ status: 'connected' | 'degraded' | 'disconnected' }>;
+
+  /**
+   * Register an inbound message handler.
+   * The adapter calls `handler` for every message received from the channel.
+   * Multiple calls replace the previous handler (last-write-wins).
+   * The handler is async; the adapter must not deliver new messages until
+   * the previous handler promise resolves (back-pressure).
+   */
+  onMessage(handler: (msg: ChannelMessage) => Promise<void>): void;
+
+  /**
+   * Send a ChannelMessage to the given channel/room/conversation.
+   * `channelId` is the channel-native identifier (e.g. Matrix room ID,
+   * Discord channel snowflake, Telegram chat ID).
+   */
+  sendMessage(channelId: string, msg: ChannelMessage): Promise<void>;
+
+  /**
+   * Map a channel-native user identifier to the Mosaic internal userId.
+   * Returns null when no matching Mosaic account exists for the given
+   * channelUserId (anonymous or unlinked user).
+   */
+  mapIdentity(channelUserId: string): Promise<string | null>;
+}
+```
+
+### Adapter Registration
+
+Adapters are registered with the `ChannelRegistry` service at startup. The registry calls `connect()` on each adapter and monitors `health()` on a configurable interval (default: 30 s).
+
+```
+ChannelRegistry
+  └── register(adapter: IChannelAdapter): void
+  └── getAdapter(name: string): IChannelAdapter | null
+  └── listAdapters(): IChannelAdapter[]
+  └── healthAll(): Promise<Record<string, AdapterHealth>>
+```

+## Channel Translation Reference
+
+The following sections document how each supported channel maps its native message format to and from `ChannelMessage`.
+
+### Matrix

+
+**Outbound:** Adapter sends `m.room.message` with `msgtype = m.text` (or `m.notice` for system messages). Markdown content is sent with `format = org.matrix.custom.html` and a rendered HTML body.
+
+---
+
+### Discord
+
+| ChannelMessage field | Discord equivalent                                                      |
+| -------------------- | ----------------------------------------------------------------------- |

+| `channelId`          | Discord channel ID (snowflake string)                                   |
+| `senderId`           | Discord user ID (snowflake)                                             |
+| `senderType`         | `"user"` for human members; `"agent"` for bot messages                  |
+| `content`            | `message.content`                                                       |
+| `contentType`        | `"markdown"` (Discord uses a markdown-like syntax natively)             |
+| `threadId`           | `message.thread.id` when the message is inside a thread channel         |
+| `replyToId`          | Mosaic ID looked up from `message.referenced_message.id`                |
+| `attachments`        | `message.attachments` mapped to `ChannelAttachment`                     |
+| `timestamp`          | `new Date(message.timestamp)`                                           |
+| `metadata`           | `{ channelMessageId, guildId, channelType, mentions, embeds }`          |
+
+**Outbound:** Adapter calls Discord REST `POST /channels/{id}/messages`. Markdown content is sent as-is (Discord renders it). For `contentType = "code"` the adapter wraps in triple-backtick fences with the `metadata.language` tag.
+
+---
+
+### Telegram
+
+| ChannelMessage field | Telegram equivalent                                                                                           |
+| -------------------- | ------------------------------------------------------------------------------------------------------------- |
+| `id`                 | Generated UUID; `metadata.channelMessageId` = Telegram `message_id` (integer)                                 |
+| `channelId`          | Telegram `chat_id` (integer as string)                                                                        |
+| `senderId`           | Telegram `from.id` (integer as string)                                                                        |
+| `senderType`         | `"user"` for human senders; `"agent"` for bot-originated messages                                             |
+| `content`            | `message.text` or `message.caption`                                                                           |
+| `contentType`        | `"text"` for plain; `"markdown"` if `parse_mode = MarkdownV2`; `"image"` for `photo`; `"file"` for `document` |
+| `threadId`           | `message.message_thread_id` (for supergroup topics)                                                           |
+| `replyToId`          | Mosaic ID looked up from `message.reply_to_message.message_id`                                                |
+| `attachments`        | `photo`, `document`, `video` fields mapped to `ChannelAttachment`                                             |
+| `timestamp`          | `new Date(message.date * 1000)`                                                                               |
+| `metadata`           | `{ channelMessageId, chatType, fromUsername, forwardFrom }`                                                   |
+
+**Outbound:** Adapter calls Telegram Bot API `sendMessage` with `parse_mode = MarkdownV2` for markdown content. For `contentType = "image"` or `"file"` it uses `sendPhoto` / `sendDocument`.
+
+---
+
+### TUI (Terminal UI)
+
+The TUI adapter bridges Mosaic's terminal interface (`packages/cli`) to the channel protocol so that TUI sessions can be treated as a first-class channel.
+
+| ChannelMessage field | TUI equivalent                                                     |
+| -------------------- | ------------------------------------------------------------------ |
+| `id`                 | Generated UUID (TUI has no native message IDs)                     |
+| `channelId`          | `"tui:<conversationId>"` — the active conversation ID              |
+| `senderId`           | Authenticated Mosaic `userId`                                      |
+| `senderType`         | `"user"` for human input; `"agent"` for agent replies              |
+| `content`            | Raw text from stdin / agent output                                 |
+| `contentType`        | `"text"` for input; `"markdown"` for agent responses               |
+| `threadId`           | Not used (TUI sessions are linear)                                 |
+| `replyToId`          | Not used                                                           |
+| `attachments`        | File paths dragged/pasted into the TUI; resolved to `file://` URLs |
+| `timestamp`          | `new Date()` at the moment of send                                 |
+| `metadata`           | `{ conversationId, sessionId, ttyWidth, colorSupport }`            |
+
+**Outbound:** The adapter writes rendered content to stdout. Markdown is rendered via a terminal markdown renderer (e.g. `marked-terminal`). Code blocks are syntax-highlighted when `metadata.colorSupport = true`.
+
+---
+
+### WebUI
+
+The WebUI adapter connects the Next.js frontend (`apps/web`) to the channel protocol over the existing Socket.IO gateway (`apps/gateway`).
+
+| ChannelMessage field | WebUI equivalent                                             |
+| -------------------- | ------------------------------------------------------------ |
+| `id`                 | Generated UUID; echoed back in the WebSocket event           |
+| `channelId`          | `"webui:<conversationId>"`                                   |
+| `senderId`           | Authenticated Mosaic `userId`                                |
+| `senderType`         | `"user"` for browser input; `"agent"` for agent responses    |
+| `content`            | Message text from the input field                            |
+| `contentType`        | `"text"` or `"markdown"`                                     |
+| `threadId`           | Not used (conversation model handles threading)              |
+| `replyToId`          | Message ID the user replied to (UI reply affordance)         |
+| `attachments`        | Files uploaded via the file picker; stored to object storage |
+| `timestamp`          | `new Date()` at send, or server timestamp from event         |
+| `metadata`           | `{ conversationId, sessionId, clientTimezone, userAgent }`   |
+
+**Outbound:** Adapter emits a `chat:message` Socket.IO event. The WebUI React component receives it and appends to the conversation list. Markdown content is rendered client-side via the existing markdown renderer component.
+
+---
+
+## Identity Mapping
+
+`mapIdentity(channelUserId)` resolves a channel-native user identifier to a Mosaic `userId`. This is required to attribute inbound messages to authenticated Mosaic accounts.
+
+The implementation must query a `channel_identities` table (or equivalent) keyed on `(channel_name, channel_user_id)`. When no mapping exists the method returns `null` and the message is treated as anonymous (no Mosaic session context).
+
+```
+channel_identities
+  channel_name   TEXT       -- e.g. "matrix", "discord"
+  channel_user_id TEXT      -- channel-native user identifier
+  mosaic_user_id  TEXT      -- FK to users.id
+  linked_at       TIMESTAMP
+  PRIMARY KEY (channel_name, channel_user_id)
+```
+
+Identity linking flows (OAuth dance, deep-link verification token, etc.) are out of scope for this document and will be specified in a separate identity-linking protocol document.
+
+---
+
+## Error Handling Conventions
+
+- `connect()` must throw a structured error (subclass of `ChannelConnectError`) if the initial connection cannot be established within a reasonable timeout (default: 10 s).
+- `sendMessage()` must throw `ChannelSendError` on terminal failures (auth revoked, channel not found). Transient failures (rate limit, network blip) should be retried internally with exponential backoff before throwing.
+- `health()` must never throw — it returns `{ status: 'disconnected' }` on error.
+- Adapters must emit structured logs with `{ channel: adapter.name, event, ... }` metadata for observability.
+
+---
+
+## Versioning
+
+The `ChannelMessage` protocol follows semantic versioning. Non-breaking field additions (new optional fields) are minor version bumps. Breaking changes (type changes, required field additions) require a major version bump and a migration guide.
+
+Current version: **1.0.0**
+
+---
+
+## M7-003: Matrix Integration Design
+
+### Homeserver Choice
+
+Mosaic uses **Conduit** as the Matrix homeserver. Conduit is written in Rust, ships as a single binary, and has minimal operational overhead compared to Synapse or Dendrite. It supports the full Matrix Client-Server and Application Service APIs required by Mosaic.
+
+Recommended deployment: Conduit runs as a Docker container alongside the Mosaic stack. A single Conduit instance is sufficient for most self-hosted deployments. Conduit's embedded RocksDB storage means no separate database is required for the homeserver itself.
+
+### Appservice Registration
+
+Mosaic registers with the Conduit homeserver as a Matrix **Application Service (appservice)**. This gives Mosaic the ability to:
+
+- Create and control ghost users (virtual Matrix users representing Mosaic agents and provisioned accounts).
+- Receive all events sent to rooms within the appservice's namespace without polling.
+- Send events on behalf of ghost users without separate authentication.
+
+Registration is done via a YAML registration file (`mosaic-appservice.yaml`) placed in Conduit's configuration directory:
+
+```yaml
+id: mosaic
+url: http://gateway:3000/_matrix/appservice
+as_token: <random-secret>
+hs_token: <random-secret>
+sender_localpart: mosaic-bot
+namespaces:
+  users:
+    - exclusive: true
+      regex: '@mosaic_.*:homeserver'
+  rooms:
+    - exclusive: false
+      regex: '.*'
+  aliases:
+    - exclusive: true
+      regex: '#mosaic-.*:homeserver'
+```
+
+The gateway exposes `/_matrix/appservice` endpoints to receive push events from Conduit. The `as_token` and `hs_token` are stored in Vault and injected at startup.
+
+### Room ↔ Conversation Mapping
+
+Each Mosaic conversation maps to a single Matrix room. The mapping is stored in the database:
+
+```
+conversation_matrix_rooms
+  conversation_id  TEXT  -- FK to conversations.id
+  room_id          TEXT  -- Matrix room ID (!roomid:homeserver)
+  created_at       TIMESTAMP
+  PRIMARY KEY (conversation_id)
+```
+
+Room creation is handled by the appservice on the first Matrix access to a conversation. Room names follow the pattern `Mosaic: <conversation title>`. Room topics contain the conversation ID for correlation.
+
+When a conversation is deleted or archived in Mosaic, the corresponding Matrix room is tombstoned (m.room.tombstone event) and the room is left in a read-only state.
+
+### Space ↔ Team Mapping
+
+Each Mosaic team maps to a Matrix **Space**. Spaces are Matrix rooms with a special `m.space` type that can contain child rooms.
+
+```
+team_matrix_spaces
+  team_id    TEXT  -- FK to teams.id
+  space_id   TEXT  -- Matrix room ID of the Space
+  created_at TIMESTAMP
+  PRIMARY KEY (team_id)
+```
+
+When a conversation room is shared with a team, the appservice adds it to the team's Space via `m.space.child` state events. Removing the share removes the child relationship.
+
+### Agent Ghost Users
+
+Each Mosaic agent is represented in Matrix as an **appservice ghost user**:
+
+- Matrix user ID format: `@mosaic_agent_<agentId>:homeserver`
+- Display name: the agent's human-readable name (e.g. "Mosaic Assistant")
+- Avatar: optional, configurable per agent
+
+Ghost users are registered lazily — the appservice creates the ghost on first use. Ghost users are controlled exclusively by the appservice; they cannot log in via Matrix client credentials.
+
+When an agent sends a message via the gateway, the Matrix adapter sends the event using `user_id` impersonation on the appservice's client endpoint, causing the message to appear as if sent by the ghost user.
+
+### Power Levels
+
+Power levels in each Mosaic-managed room are set as follows:
+
+| Entity                                | Power Level    | Rationale                              |
+| ------------------------------------- | -------------- | -------------------------------------- |
+| Mosaic appservice bot (`@mosaic-bot`) | 100 (Admin)    | Room management and moderation         |
+| Human Mosaic users                    | 50 (Moderator) | Can kick, redact, and invite           |
+| Agent ghost users                     | 0 (Default)    | Message-only; cannot modify room state |
+
+This arrangement ensures human users retain full control. An agent cannot modify room settings, kick members, or take administrative actions. Humans with moderator power can redact agent messages and intervene in ongoing conversations.
+
+```

+
+## M7-004: Conversation Multiplexing
+
+### Architecture Overview
+
+A single Mosaic conversation can be accessed simultaneously from multiple surfaces: TUI, WebUI, and Matrix. The gateway is the **single source of truth** for all conversation state. Each surface is a thin client that renders gateway-owned data.
+
+```

+```
+
+### Real-Time Sync Flow
+
+1. A message arrives on any surface (TUI keystroke, browser send, Matrix event).
+2. The surface's adapter normalizes the message to `ChannelMessage` and delivers it to `ConversationService`.
+3. `ConversationService` persists the message to PostgreSQL, assigns a canonical `id`, and publishes a `message:new` event to the Valkey pub/sub channel keyed by `conversationId`.
+4. All active surfaces subscribed to that `conversationId` receive the fanout event and push it to their respective clients:
+   - TUI adapter: writes rendered output to the connected terminal session.
+   - WebUI adapter: emits a `chat:message` Socket.IO event to all browser sessions joined to that conversation.
+   - Matrix adapter: sends an `m.room.message` event to the conversation's Matrix room.
+
+This ensures that a message typed in the TUI appears in the browser and in Matrix within the same round-trip latency as the Valkey fanout (typically <10 ms on co-located infrastructure).
+
+### Surface-to-Transport Mapping
+
+| Surface | Transport to Gateway                       | Fanout Transport from Gateway |
+| ------- | ------------------------------------------ | ----------------------------- |
+| TUI     | HTTPS REST + SSE or WebSocket              | Socket.IO over stdio proxy    |
+| WebUI   | Socket.IO (browser)                        | Socket.IO emit                |
+| Matrix  | Matrix Client-Server API (appservice push) | Matrix `m.room.message` send  |
+
+### Conflict Resolution
+
+- **Messages**: Append-only. Messages are never edited in-place in Mosaic's canonical store. Matrix edit events (`m.replace`) are treated as new messages with `replyToId` pointing to the original, preserving the full audit trail.
+- **Metadata (title, tags, archived state)**: Last-write-wins. The timestamp of the most recent write wins. Concurrent metadata updates from different surfaces are serialized through `ConversationService`; the final database write reflects the last persisted value.
+- **Conversation membership**: Set-merge semantics. Adding a user from any surface is additive. Removal requires an explicit delete action and is not overwritten by concurrent adds.
+
+### Session Isolation
+
+Multiple TUI sessions or browser tabs connected to the same conversation receive all fanout messages independently. Each session maintains its own scroll position and local ephemeral state (typing indicator, draft text). Gateway does not synchronize ephemeral state across sessions.
+

+
+## M7-005: Remote Auth Bridging
+
+### Overview
+
+Matrix users authenticate to Mosaic by linking their Matrix identity to an existing Mosaic account. There are two flows: token linking (primary) and OAuth bridge (alternative). Once linked, the Matrix session is persistent — there is no periodic login/logout cycle.
+
+### Token Linking Flow
+
+1. A Mosaic admin or the user themselves generates a short-lived link token via the Mosaic web UI or API (`POST /auth/channel-link-token`). The token is a cryptographically random 32-byte hex string with a 15-minute TTL stored in Valkey.
+2. The user opens a Matrix client and sends a DM to `@mosaic-bot:homeserver`.
+3. The user sends the command: `!link <token>`
+4. The appservice receives the `m.room.message` event in the DM room, extracts the token, and calls `AuthService.linkChannelIdentity({ channel: 'matrix', channelUserId: matrixUserId, token })`.
+5. `AuthService` validates the token, retrieves the associated `mosaicUserId`, and writes a row to `channel_identities`.
+6. The appservice sends a confirmation reply in the DM room and invites the now-linked user to their personal Matrix Space.
+
+```
+User (Matrix)          @mosaic-bot          Mosaic Gateway
+     │                     │                      │

+     │                     │─────────────────────▶│
+     │                     │   200 OK             │
+     │                     │◀─────────────────────│
+     │  ✓ Linked! Joining  │                      │
+     │  your Space now     │                      │
+     │◀────────────────────│                      │
+```
+
+### OAuth Bridge Flow
+
+An alternative flow for users who prefer browser-based authentication:
+
+1. The Mosaic bot sends the user a Matrix message containing an OAuth URL: `https://mosaic.example.com/auth/matrix-link?state=<nonce>&matrix_user=<encoded_mxid>`
+2. The user opens the URL in a browser. If not already logged in to Mosaic, they are redirected through the standard BetterAuth login flow.
+3. On successful authentication, Mosaic records the `channel_identities` row linking `matrix_user` to the authenticated `mosaicUserId`.
+4. The gateway sends a Matrix event to the pending DM room confirming the link.
+
+### Invite-Based Provisioning
+
+When a Mosaic admin adds a new user account, the provisioning flow optionally associates a Matrix user ID with the new account at creation time:
+
+1. Admin provides `matrixUserId` when creating the account (`POST /admin/users`).
+2. `UserService` writes the `channel_identities` row immediately.
+3. The Matrix adapter's provisioning hook fires, and the appservice:
+   - Creates the user's personal Matrix Space (if not already existing).
+   - Sends an invite to the Matrix user for their personal Space.
+   - Sends a welcome DM from `@mosaic-bot` with onboarding instructions.
+
+The invited user does not need to complete any linking step — the association is pre-established by the admin.
+
+### Session Lifecycle
+
+Matrix sessions for linked users are persistent and long-lived. Unlike TUI sessions (which terminate when the terminal process exits), a Matrix user's access to their rooms remains intact as long as:
+
+- Their Mosaic account is active (not suspended or deleted).
+- Their `channel_identities` row exists (link not revoked).
+- They remain members of the relevant Matrix rooms.
+
+Revoking a Matrix link (`DELETE /auth/channel-link/matrix/<matrixUserId>`) removes the `channel_identities` row and causes `mapIdentity()` to return `null`. The appservice optionally kicks the Matrix user from all Mosaic-managed rooms as part of the revocation flow (configurable, default: off).
+
+---
+
+## M7-006: Agent-to-Agent Communication via Matrix
+
+### Dedicated Agent Rooms
+
+When two Mosaic agents need to coordinate, a dedicated Matrix room is created for their dialogue. This provides a persistent, auditable channel for structured inter-agent communication that humans can observe.
+
+Room naming convention:
+
+```
+#mosaic-agents-<agentA>-<agentB>:homeserver
+```
+
+Where `agentA` and `agentB` are the Mosaic agent IDs sorted lexicographically (to ensure the same room is used regardless of which agent initiates). The room alias is registered by the appservice.
+
+```
+agent_rooms
+  room_id     TEXT  -- Matrix room ID
+  agent_a_id  TEXT  -- FK to agents.id (lexicographically first)
+  agent_b_id  TEXT  -- FK to agents.id (lexicographically second)
+  created_at  TIMESTAMP
+  PRIMARY KEY (agent_a_id, agent_b_id)
+```
+
+### Room Membership and Power Levels
+
+| Entity                             | Power Level                          |
+| ---------------------------------- | ------------------------------------ |
+| Mosaic appservice bot              | 100 (Admin)                          |
+| Human observers (invited)          | 50 (Moderator, read-only by default) |
+| Agent ghost users (agentA, agentB) | 0 (Default — message send only)      |
+
+Humans are invited to agent rooms with a read-only intent. By convention, human messages in agent rooms are prefixed with `[HUMAN]` and treated as interrupts by the gateway. Agents are instructed (via system prompt) to pause and acknowledge human messages before resuming their dialogue.
+
+### Message Format
+
+Agents communicate using **structured JSON** embedded in Matrix event content. The Matrix event type is `m.room.message` with `msgtype: "m.text"` for compatibility. The structured payload is carried in a custom `mosaic.agent_message` field:
+
+```json
+{
+  "msgtype": "m.text",
+  "body": "[Agent message — see mosaic.agent_message for structured content]",
+  "mosaic.agent_message": {
+    "schema_version": "1.0",
+    "sender_agent_id": "agent_abc123",
+    "conversation_id": "conv_xyz789",
+    "message_type": "request",
+    "payload": {
+      "action": "summarize",
+      "parameters": { "max_tokens": 500 },
+      "reply_to_event_id": "$previousEventId"
+    },
+    "timestamp_ms": 1711234567890
+  }
+}
+```
+
+The `body` field contains a human-readable fallback so the conversation is legible in any Matrix client. The structured payload is parsed exclusively by the gateway's Matrix adapter.
+
+### Coordination Patterns
+
+**Request/Response**: Agent A sends a `message_type: "request"` event. Agent B sends a `message_type: "response"` with `reply_to_event_id` referencing Agent A's event. The gateway correlates request/response pairs using the event IDs.
+
+**Broadcast**: An agent sends a `message_type: "broadcast"` to a multi-agent room (more than two members). All agents in the room receive the event. No response is expected.
+
+**Delegation**: Agent A sends a `message_type: "delegate"` with a `payload.task` object describing work to be handed off to Agent B. Agent B acknowledges with `message_type: "delegate_ack"` and later sends `message_type: "delegate_complete"` when done.
+
+```
+AgentA                Gateway               AgentB
+  │   delegate(task)    │                     │
+  │────────────────────▶│                     │
+  │                     │  Matrix event push  │
+  │                     │────────────────────▶│
+  │                     │  delegate_ack       │
+  │                     │◀────────────────────│
+  │                     │  [AgentB executes]  │
+  │                     │  delegate_complete  │
+  │                     │◀────────────────────│
+  │  task result        │                     │
+  │◀────────────────────│                     │
+```
+
+### Gateway Mediation
+
+Agents do not call the Matrix Client-Server API directly. All inter-agent Matrix events are sent and received by the gateway's appservice. This means:
+
+- The gateway can intercept, log, and rate-limit agent-to-agent messages.
+- Agents that are offline (no active process) still have their messages delivered; the gateway queues them and delivers on the agent's next activation.
+- The gateway can inject system messages (e.g. human interrupts, safety stops) into agent rooms without agent cooperation.
+

+
+## M7-007: Multi-User Isolation in Matrix
+
+### Space-per-Team Architecture
+
+Isolation in Matrix is enforced through the Space hierarchy. Each organizational boundary in Mosaic maps to a distinct Matrix Space:
+
+| Mosaic entity                 | Matrix Space   | Visibility        |
+| ----------------------------- | -------------- | ----------------- |
+| Personal workspace (per user) | Personal Space | User only         |
+| Team                          | Team Space     | Team members only |
+| Public project                | (no Space)     | Configurable      |
+
+Rooms (conversations) are placed into Spaces based on their sharing configuration. A room can appear in at most one team Space at a time. Moving a room from one team Space to another removes the `m.space.child` link from the old Space and adds it to the new one.
+
+### Room Visibility Rules
+
+Matrix room visibility within Conduit is controlled by:
+
+1. **Join rules**: All Mosaic-managed rooms use `join_rule: invite`. Users cannot discover or join rooms without an explicit invite from the appservice.
+2. **Space membership**: Rooms appear in a Space's directory only to users who are members of that Space.
+3. **Room directory**: The server room directory is disabled for Mosaic-managed rooms (`m.room.history_visibility: shared` for team rooms, `m.room.history_visibility: invited` for personal rooms).
+
+### Personal Space Defaults
+
+When a user account is created (or linked to Matrix), the appservice provisions a personal Space:
+
+- Space name: `<username>'s Space`
+- All conversations the user creates personally are added as children of their personal Space.
+- No other users are members of this Space by default.
+- Conversation rooms within the personal Space are only visible and accessible to the owner.
+
+### Team Shared Rooms
+
+When a project or conversation is shared with a team:
+
+1. The appservice adds the room as a child of the team's Space (`m.space.child` state event in the Space room, `m.space.parent` state event in the conversation room).
+2. All current team members are invited to the conversation room.
+3. Newly added team members are automatically invited to all shared rooms in the team's Space by the appservice's team membership hook.
+4. If sharing is revoked, the appservice removes the `m.space.child` link and kicks all team members who joined via the team share (users who were directly invited are unaffected).
+
+### Encryption
+
+Encryption is optional and configured per room at creation time. Recommended defaults:
+
+| Space type     | Encryption default | Rationale                              |
+| -------------- | ------------------ | -------------------------------------- |
+| Personal Space | Enabled            | Privacy-first for individual users     |
+| Team Space     | Disabled           | Operational visibility; admin auditing |
+| Agent rooms    | Disabled           | Gateway must read structured payloads  |
+
+When encryption is enabled, the appservice's ghost users must participate in key exchange (using Matrix's Olm/Megolm protocol). The gateway holds the device keys for all ghost users it controls. This constraint means encrypted rooms require the gateway to be the E2E session holder — messages are end-to-end encrypted between human clients and gateway-held ghost device keys, not between human clients themselves.
+
+### Admin Visibility
+
+A Conduit server administrator can see:
+
+- Room metadata: names, aliases, topic, membership list.
+- Unencrypted event content in unencrypted rooms.
+
+A Conduit server administrator **cannot** see:
+
+- Content of encrypted rooms (without holding a device key for a room member).
+
+Mosaic does not grant gateway admin credentials to application-level admin users. The Conduit admin interface is restricted to infrastructure operators. Application-level admins manage users and rooms through the Mosaic API, which interacts with the appservice layer only.
+
+### Data Retention
+
+Matrix events in Mosaic-managed rooms follow Mosaic's configurable retention policy:
+
+```
+room_retention_policies
+  room_id          TEXT   -- Matrix room ID (or wildcard pattern)
+  retention_days   INT    -- NULL = keep forever
+  applies_to       TEXT   -- "personal" | "team" | "agent" | "all"
+  created_at       TIMESTAMP
+```
+
+The retention policy is enforced by a background job in the gateway that calls Conduit's admin API to purge events older than the configured threshold. Purged events are removed from the Conduit store but Mosaic's PostgreSQL message store retains the canonical `ChannelMessage` record unless the Mosaic retention policy also covers it.
+
+Default retention values:
+
+| Room type                   | Default retention   |
+| --------------------------- | ------------------- |
+| Personal conversation rooms | 365 days            |
+| Team conversation rooms     | 730 days            |
+| Agent-to-agent rooms        | 90 days             |
+| System/audit rooms          | 1825 days (5 years) |
+
+Retention settings are configurable by Mosaic admins via the admin API and apply to both the Matrix event store and the Mosaic message store in lockstep.

+```
+
+The gateway imports the interface, not the backend. At startup it reads config and instantiates the correct adapter.
+
+## The Drift
+
+```typescript
+// What should have happened:
+gateway/queue.service.ts → @mosaic/queue (interface) → queue.adapter.ts
+
+// What actually happened:
+gateway/queue.service.ts → @mosaic/queue → ioredis (hardcoded)
+```
+
+## The Current State Analysis
+
+### `@mosaic/queue` (packages/queue/src/queue.ts)
+
+```typescript
+import Redis from 'ioredis'; // ← Direct import of backend
+
+export function createQueue(config?: QueueConfig): QueueHandle {
+  const url = config?.url ?? process.env['VALKEY_URL'] ?? DEFAULT_VALKEY_URL;
+  const redis = new Redis(url, { maxRetriesPerRequest: 3 });
+  // ...queue ops directly on redis...
+}
+```
+
+**Problem:** `ioredis` is imported in the package, not the adapter interface. Consumers cannot swap backends.
+
+### `@mosaic/db` (packages/db/src/client.ts)
+
+```typescript
+import { drizzle, type PostgresJsDatabase } from 'drizzle-orm/postgres-js';
+import postgres from 'postgres';
+
+export function createDb(url?: string): DbHandle {
+  const connectionString = url ?? process.env['DATABASE_URL'] ?? DEFAULT_DATABASE_URL;
+  const sql = postgres(connectionString, { max: 20, idle_timeout: 30, connect_timeout: 5 });
+  const db = drizzle(sql, { schema });
+  // ...
+}
+```
+
+**Problem:** Drizzle + Postgres is hardcoded. No SQLite, JSON, or file-based options.
+
+### `@mosaic/memory` (packages/memory/src/memory.ts)
+
+```typescript
+import type { Db } from '@mosaic/db'; // ← Depends on Drizzle/PG
+
+export function createMemory(db: Db): Memory {
+  return {
+    preferences: createPreferencesRepo(db),
+    insights: createInsightsRepo(db),
+  };
+}
+```
+
+**Problem:** Memory package is tightly coupled to `@mosaic/db` (which is Postgres-only). No alternative storage backends.
+
+## The Target Interfaces
+
+### Queue Interface
+
+```typescript
+// packages/queue/src/types.ts
+export interface QueueAdapter {
+  readonly name: string;
+
+  enqueue(queueName: string, payload: TaskPayload): Promise<void>;

+  id: string;
+  type: string;
+  data: Record<string, unknown>;
+  createdAt: string;
+}
+
+export interface QueueConfig {
+  type: 'bullmq' | 'local';
+  url?: string; // For bullmq: Valkey/Redis URL
+  dataDir?: string; // For local: directory for JSON persistence
+}
+```
+
+### Storage Interface
+
+```typescript
+// packages/storage/src/types.ts
+export interface StorageAdapter {
+  readonly name: string;
+
+  // Entity CRUD
+  create<T>(collection: string, data: O): Promise<T>;

+  updateMany<T>(collection: string, ids: string[], data: Partial<O>): Promise<number>;
+  deleteMany(collection: string, ids: string[]): Promise<number>;
+
+  // Raw queries (for complex queries)
+  query<T>(collection: string, query: string, params?: unknown[]): Promise<T[]>;
+
+  // Transaction support
+  transaction<T>(fn: (tx: StorageTransaction) => Promise<T>): Promise<T>;
+
+  close(): Promise<void>;
+}
+
+export interface StorageTransaction {
+  commit(): Promise<void>;
+  rollback(): Promise<void>;
+}
+
+export interface StorageConfig {
+  type: 'postgres' | 'sqlite' | 'files';
+  url?: string;      // For postgres
+  path?: string;      // For sqlite/files
+}
+```
+
+### Memory Interface (Vector + Preferences)
+
+```typescript
+// packages/memory/src/types.ts
+export interface MemoryAdapter {
+  readonly name: string;
+
+  // Preferences (key-value storage)
+  getPreference(userId: string, key: string): Promise<unknown | null>;
+  setPreference(userId: string, key: string, value: unknown): Promise<void>;
+  deletePreference(userId: string, key: string): Promise<boolean>;
+  listPreferences(
+    userId: string,
+    category?: string,
+  ): Promise<Array<{ key: string; value: unknown }>>;
+
+  // Insights (with optional vector search)
+  storeInsight(insight: NewInsight): Promise<Insight>;
+  getInsight(id: string): Promise<Insight | null>;
+  searchInsights(query: string, limit?: number, filter?: InsightFilter): Promise<SearchResult[]>;

+
+## Three Tiers
+
+### Tier 1: Local (Zero Dependencies)
+
+**Target:** Single user, single machine, no external services
+
+| Component | Backend                                       | Storage      |
+| --------- | --------------------------------------------- | ------------ |
+| Queue     | In-process + JSON files in `~/.mosaic/queue/` |
+| Storage   | SQLite (better-sqlite3) `~/.mosaic/data.db`   |
+| Memory    | Keyword search                                | SQLite table |
+| Vector    | None                                          | N/A          |
+
+**Dependencies:**
+
+- `better-sqlite3` (bundled)
+- No Postgres, No Valkey, No pgvector
+
+**Upgrade path:**
+
+1. Run `mosaic gateway configure` → select "local" tier
+2. Gateway starts with SQLite database
+3. Optional: run `mosaic gateway upgrade --tier team` to migrate to Postgres
+
+### Tier 2: Team (Postgres + Valkey)
+
+**Target:** Multiple users, shared server, CI/CD environments
+
+| Component | Backend        | Storage                        |
+| --------- | -------------- | ------------------------------ |
+| Queue     | BullMQ         | Valkey                         |
+| Storage   | Postgres       | Shared PG instance             |
+| Memory    | pgvector       | Postgres with vector extension |
+| Vector    | LLM embeddings | Configured provider            |
+
+**Dependencies:**
+
+- PostgreSQL 17+ with pgvector extension
+- Valkey (Redis-compatible)
+- LLM provider for embeddings
+
+**Migration from Local → Team:**
+
+1. `mosaic gateway backup` → creates dump of SQLite database
+2. `mosaic gateway upgrade --tier team` → restores to Postgres
+3. Queue replays from BullMQ (may need manual reconciliation for in-flight jobs)
+4. Memory embeddings regenerated if vector search was new
+
+### Tier 3: Enterprise (Clustered)
+
+**Target:** Large teams, multi-region, high availability
+
+| Component | Backend                     | Storage                       |
+| --------- | --------------------------- | ----------------------------- |
+| Queue     | BullMQ cluster              | Multiple Valkey nodes         |
+| Storage   | Postgres cluster            | Primary + replicas            |
+| Memory    | Dedicated vector DB         | Qdrant, Pinecone, or pgvector |
+| Vector    | Dedicated embedding service | Separate microservice         |
+
+## MarkdownDB Integration
+
+For file-based storage, we use [MarkdownDB](https://markdowndb.com) to parse MD files into queryable data.
+
+**What it provides:**
+
+- Parses frontmatter (YAML/JSON/TOML)
+- Extracts links, tags, metadata
+- Builds index in JSON or SQLite
+- Queryable via SQL-like interface
+
+**Usage in Mosaic:**
+
+```typescript
+// Local tier with MD files for documents
+const storage = createStorageAdapter({
+  type: 'files',
+  path: path.join(mosaicHome, 'docs'),
+  markdowndb: {
+    parseFrontmatter: true,
+    extractLinks: true,
+    indexFile: 'index.json',
+  },
+});
+```
+
+## Dream Mode — Memory Consolidation
+
+Automated equivalent to Claude Code's "Dream: Memory Consolidation" cycle
+
+**Trigger:** Every 24 hours (if 5+ sessions active)
+
+**Phases:**
+
+1. **Orient** — What happened, what's the current state
+   - Scan recent session logs
+   - Identify active tasks, missions, conversations
+   - Calculate time window (last 24h)
+
+2. **Gather** — Pull in relevant context
+   - Load conversations, decisions, agent logs
+   - Extract key interactions and outcomes
+   - Identify patterns and learnings
+
+3. **Consolidate** — Summarize and compress
+   - Generate summary of the last 24h
+   - Extract key decisions and their rationale
+   - Identify recurring patterns
+   - Compress verbose logs into concise insights
+
+4. **Prune** — Archive and cleanup
+   - Archive raw session files to dated folders
+   - Delete redundant/temporary data
+   - Update MEMORY.md with consolidated content
+   - Update insight relevance scores
+
+**Implementation:**
+
+```typescript
+// In @mosaic/dream (new package)
+export async function runDreamCycle(config: DreamConfig): Promise<DreamResult> {
+  const memory = await loadMemoryAdapter(config.storage);
+
+  // Orient
+  const sessions = await memory.getRecentSessions(24 * 60 * 60 * 1000);
+  if (sessions.length < 5) return { skipped: true, reason: 'insufficient_sessions' };
+
+  // Gather
+  const context = await gatherContext(memory, sessions);
+
+  // Consolidate
+  const consolidated = await consolidateWithLLM(context, config.llm);
+
+  // Prune
+  await pruneArchivedData(memory, config.retention);
+
+  // Store consolidated insights
+  await memory.storeInsights(consolidated.insights);
+
+  return {
+    sessionsProcessed: sessions.length,
+    insightsCreated: consolidated.insights.length,
+    bytesPruned: consolidated.bytesRemoved,
+  };
+}
+```
+
+---
+
+## Retrofit Plan
+
+### Phase 1: Interface Extraction (2-3 days)
+
+**Goal:** Define interfaces without changing existing behavior
+
+1. Create `packages/queue/src/types.ts` with `QueueAdapter` interface
+2. Create `packages/storage/src/types.ts` with `StorageAdapter` interface
+3. Create `packages/memory/src/types.ts` with `MemoryAdapter` interface (refactor existing)
+4. Add adapter registry pattern to each package
+5. No breaking changes — existing code continues to work
+
+### Phase 2: Refactor Existing to Adapters (3-5 days)
+
+**Goal:** Move existing implementations behind adapters
+
+#### 2.1 Queue Refactor
+
+1. Rename `packages/queue/src/queue.ts` → `packages/queue/src/adapters/bullmq.ts`
+2. Create `packages/queue/src/index.ts` to export factory function
+3. Factory function reads config, instantiates correct adapter
+4. Update gateway imports to use factory
+
+#### 2.2 Storage Refactor
+
+1. Create `packages/storage/` (new package)
+2. Move Drizzle logic to `packages/storage/src/adapters/postgres.ts`
+3. Create SQLite adapter in `packages/storage/src/adapters/sqlite.ts`
+4. Update gateway to use storage factory
+5. Deprecate direct `@mosaic/db` imports
+
+#### 2.3 Memory Refactor
+
+1. Extract existing logic to `packages/memory/src/adapters/pgvector.ts`
+2. Create keyword adapter in `packages/memory/src/adapters/keyword.ts`
+3. Update vector-store.ts to be adapter-agnostic
+
+### Phase 3: Local Tier Implementation (2-3 days)
+
+**Goal:** Zero-dependency baseline
+
+1. Implement `packages/queue/src/adapters/local.ts` (in-process + JSON persistence)
+2. Implement `packages/storage/src/adapters/files.ts` (JSON + MD via MarkdownDB)
+3. Implement `packages/memory/src/adapters/keyword.ts` (TF-IDF search)
+4. Add `packages/dream/` for consolidation cycle
+5. Wire up local tier in gateway startup
+
+### Phase 4: Configuration System (1-2 days)
+
+**Goal:** Runtime backend selection
+
+1. Create `packages/config/src/storage.ts` for storage configuration
+2. Add `mosaic.config.ts` schema with storage tier settings
+3. Update gateway to read config on startup
+4. Add `mosaic gateway configure` CLI command
+5. Add tier migration commands (`mosaic gateway upgrade`)
+
+### Phase 5: Testing & Documentation (2-3 days)
+
+1. Unit tests for each adapter
+2. Integration tests for factory pattern
+3. Migration tests (local → team)
+4. Update README and architecture docs
+5. Add configuration guide

+## Breaking Changes
+
+1. **`@mosaic/db`** → **`@mosaic/storage`** (with migration guide)
+2. Direct `ioredis` imports → Use `@mosaic/queue` factory
+3. Direct `pgvector` queries → Use `@mosaic/memory` factory
+4. Gateway startup now requires storage config (defaults to local)
+
+## Non-Breaking Migration Path
+
+1. Existing deployments with Postgres/Valkey continue to work (default config)
+2. New deployments can choose local tier
+3. Migration commands available when ready to upgrade
+
+---
+
+## Success Criteria
+
+- [ ] Local tier runs with zero external dependencies
+- [ ] All three tiers (local, team, enterprise) work correctly
+- [ ] Factory pattern correctly selects backend at runtime
+- [ ] Migration from local → team preserves all data
+- [ ] Dream mode consolidates 24h of sessions
+- [ ] Documentation covers all three tiers and migration paths
+- [ ] All existing tests pass
+- [ ] New adapters have >80% coverage

+# Scratchpad: CI Docker Publish (2026-03-30)
+
+- Objective: Add Woodpecker Docker build+push steps for gateway and web images on `main` pushes.
+- Scope: `.woodpecker/ci.yml`.
+- Constraints:
+  - Use existing Dockerfiles at `docker/gateway.Dockerfile` and `docker/web.Dockerfile`.
+  - Publish to `git.mosaicstack.dev` with `from_secret` credentials.
+  - Tag both `latest` and `${CI_COMMIT_SHA}`.
+  - Do not run publish steps on pull requests.
+- ASSUMPTION: Publishing `latest` is required by the task for registry convenience, even though immutable tags remain the safer deployment reference.
+- Findings:
+  - Existing pipeline already has `build` after `lint`, `format`, and `test`.
+  - `apps/gateway/package.json` uses `tsc` for `build`; no Prisma dependency or `prisma generate` hook is present.
+- Plan:
+  1. Patch `.woodpecker/ci.yml` to keep `build` as the quality gate successor and add `publish-gateway` plus `publish-web`.
+  2. Validate YAML and run repo quality gates relevant to the change.
+  3. Review the diff, then commit/push/PR if validation passes.
+- Verification:
+  - `python3 -c "import yaml; yaml.safe_load(open('.woodpecker/ci.yml'))" && echo "YAML valid"`
+  - `pnpm lint`
+  - `pnpm typecheck`
+  - `pnpm format:check`
+  - `docker compose up -d`
+  - `pnpm --filter @mosaic/db db:push`
+  - `pnpm test`
+  - `pnpm build`
+  - Manual review of `.woodpecker/ci.yml` diff: publish steps are main-only, depend on `build`, and use secret-backed registry auth plus dual tags.
+- Risks:
+  - Pipeline behavior beyond YAML validation cannot be fully proven locally; remote Woodpecker execution will be the final situational check after push.
+  - Repo baseline required two existing `plugins/macp` files to be reformatted before `pnpm format:check` would pass.

+# Scratchpad — fix-ci-migrations-20260330
+
+## Objective
+
+- Fix Drizzle migration journal ordering so fresh Postgres instances apply all schema migrations in CI.
+
+## Plan
+
+- Inspect migration SQL, journal, and snapshot chain.
+- Patch metadata consistently.
+- Run full test suite.
+- Record result and risks.
+
+## Progress
+
+- Inspected migration files and confirmed 0001_cynical_ultimatum.sql is missing from journal while 0002 depends on it.
+- Patched `packages/db/drizzle/meta/_journal.json` to insert `0001_cynical_ultimatum` at idx 1 and shift later entries to idx 2-7.
+- Verified snapshot content is already semantically aligned with the fixed ordering: the missing tables exist in `0001_snapshot.json`, and `mutable` appears in later snapshots.
+- Installed workspace dependencies in this worktree to make the requested test command runnable.
+- Ran `pnpm test` successfully; gateway reported `347 passed (347)` and Turbo finished with `35 successful, 35 total`.

+# Task Scratchpad — Turbo DATABASE_URL passthrough
+
+## Objective
+
+- Fix CI test execution under Turborepo by passing DB-related environment variables through the `test` task.
+- Preserve the repo's documented local Postgres fallback on host port `5433`.
+
+## Scope
+
+- Edit `turbo.json`
+- Run baseline checks requested by the user and repo rules where feasible
+- Publish branch and open PR if checks are acceptable
+
+## Assumptions
+
+- ASSUMPTION: No PRD update is required because this is a narrow CI/config bug fix that does not change product requirements.
+- ASSUMPTION: `docs/TASKS.md` remains untouched because project guidance marks it orchestrator-only.
+- ASSUMPTION: Local Postgres-backed tests are not runnable in this worktree, so baseline verification will rely on static gates unless the environment already provides DB access.
+
+## Plan
+
+- Record current repo state and avoid touching `.mosaic/orchestrator/session.lock`
+- Add Turbo DB env declarations for test execution and cache invalidation
+- Run `pnpm format:check`, `pnpm typecheck`, and `pnpm lint`
+- Review the diff, then commit/push/PR via provider-appropriate flow
+
+## Verification Log
+
+- `pnpm install` completed in this worktree so repo tooling is available
+- `pnpm format:check` initially failed on `turbo.json`; fixed by formatting the file
+- `pnpm format:check` passed after formatting
+- `pnpm typecheck` passed
+- `pnpm lint` passed
+- Independent review flagged two important adjustments:
+  - keep `DEFAULT_DATABASE_URL` on `5433` because local Docker Compose maps host `5433 -> container 5432`
+  - prefer Turbo `env` over `passThroughEnv` so DB config changes also affect the test cache key
+
+## Risks
+
+- Existing mission/orchestrator files are dirty in the worktree and must be excluded from the scoped change.
+- Local tests were not run because no Postgres service is available in this worktree; CI remains the primary situational validation for the test-task behavior.

+# Mission Scratchpad — Harness Foundation
+
+> Append-only log. NEVER delete entries. NEVER overwrite sections.
+> This is the orchestrator's working memory across sessions.
+
+## Original Mission Prompt
+
+```
+Jason wants to get the gateway and TUI working as a real daily-driver harness.
+The system needs: multi-provider LLM access, task-aware agent routing, conversation persistence,
+security isolation, session hardening, job queue foundation, and channel protocol design for
+future Matrix/remote integration.
+
+Provider decisions: Anthropic (Sonnet 4.6, Opus 4.6), OpenAI (Codex gpt-5.4), Z.ai (GLM-5),
+OpenRouter, Ollama. Embeddings via Ollama local models.
+
+Pi SDK stays as agent runtime. Build with Matrix integration in mind but foundation first.
+Agent routing per task with granular specification is required.
+```
+
+## Planning Decisions
+
+### 2026-03-21 — Phase 9 PRD and mission setup
+
+- PRD created as `docs/PRD-Harness_Foundation.md` with canonical Mosaic template format
+- 7 milestones, 71 tasks total
+- Milestone order: M1 (persistence) → M2 (security) → M3 (providers) → M4 (routing) → M5 (sessions) → M6 (jobs) → M7 (channel design)
+- M1 and M2 are hard prerequisites — no provider or routing work until conversations persist and data is user-scoped
+- Pi SDK kept as agent runtime; providers plug in via adapter pattern underneath
+- Embeddings migrated from OpenAI to Ollama local (nomic-embed-text or mxbai-embed-large)
+- BullMQ chosen for job queue (Valkey-compatible, TypeScript-native)
+- Channel protocol is design-only in this phase; Matrix implementation deferred to Phase 10
+- Models confirmed: Claude Sonnet 4.6, Opus 4.6, Haiku 4.5, Codex gpt-5.4, GLM-5, Ollama locals
+- Routing engine: rule-based classification first, LLM-assisted later
+- Default routing: coding-complex→Opus, coding-moderate→Sonnet, coding-simple→Codex, research→Codex, summarization→GLM-5, conversation→Sonnet, cheap/general→Haiku, offline→Ollama
+
+### Architecture decisions
+
+- Provider adapter pattern: each provider implements IProviderAdapter, registered in Pi SDK's provider registry
+- Routing flow: classify message → match rules by priority → check provider health → fallback chain → dispatch
+- Context window management: summarize older messages when history exceeds 80% of model context
+- OAuth pattern: URL-display + clipboard + Valkey poll token (same as P8-012 design)
+- Embedding dimension: migration from 1536 (OpenAI) to 768/1024 (Ollama) — may require re-embedding existing insights

+# M3-001 Provider Adapter Pattern — Scratchpad
+
+## Objective
+
+Refactor ProviderService into an IProviderAdapter pattern without breaking existing Ollama flow.
+
+## Plan
+
+1. Add `IProviderAdapter` interface and supporting types to `@mosaic/types` provider package
+2. Create `apps/gateway/src/agent/adapters/` directory with:
+   - `provider-adapter.interface.ts` — IProviderAdapter + ProviderHealth + CompletionParams + CompletionEvent
+   - `ollama.adapter.ts` — extract existing Ollama logic
+3. Refactor ProviderService:
+   - Accept `IProviderAdapter[]` (injected via DI token)
+   - `registerAll()` / `listModels()` aggregates from all adapters
+   - `getAdapter(name)` — lookup by name
+   - `healthCheckAll()` — check all adapters
+   - Keep Pi ModelRegistry wiring (required by AgentService)
+4. Wire up in AgentModule
+
+## Key Findings
+
+### Pi SDK Compatibility
+
+- Pi SDK uses `ModelRegistry` as central registry; ProviderService wraps it
+- `ModelRegistry.registerProvider()` is the integration point — adapters call this
+- Pi doesn't have a native "IProviderAdapter" concept — adapters are a Mosaic abstraction on top
+- The `createAgentSession()` call in AgentService uses `modelRegistry: this.providerService.getRegistry()`
+- OllamaAdapter should call `registry.registerProvider('ollama', {...})` same as today
+- CompletionParams/CompletionEvent: Pi SDK streams via `AgentSession.prompt()`, not raw completion
+  — IProviderAdapter.createCompletion() is for future direct use; for now stub or leave as interface-only
+  — ASSUMPTION: createCompletion is reserved for future M3+ work; Pi SDK owns the actual streaming
+
+## Implementation Notes
+
+- ESM: use `.js` extensions in all imports
+- NestJS: use `@Inject()` explicitly
+- Keep RoutingService working — it only uses `providerService.listAvailableModels()`
+- Keep AgentService working — it uses `providerService.getRegistry()`, `findModel()`, `getDefaultModel()`, `listAvailableModels()`
+
+## Progress
+
+- [ ] Add types to @mosaic/types
+- [ ] Create adapters/ directory
+- [ ] Create IProviderAdapter interface file
+- [ ] Create OllamaAdapter
+- [ ] Refactor ProviderService
+- [ ] Update AgentModule
+- [ ] Run tests
+- [ ] Run quality gates
+
+## Risks
+
+- Pi SDK doesn't natively support IProviderAdapter — adapters are a layer on top
+- createCompletion() is architecturally sound but requires Pi session bypass (future work)

+# Scratchpad: MACP OC Bridge (2026-03-30)
+
+- Objective: Replace the OpenClaw MACP plugin's Pi-direct `runTurn` with the MACP controller queue bridge.
+- Scope: `plugins/macp/src/macp-runtime.ts`, `plugins/macp/src/index.ts`, `plugins/macp/openclaw.plugin.json`, `plugins/macp/README.md`.
+- Plan:
+  1. Read controller/dispatcher/plugin docs and confirm queue/result contract.
+  2. Queue tasks through `.mosaic/orchestrator/tasks.json` using a brief file and controller trigger.
+  3. Poll result JSON, stream output back to ACP, then validate with typecheck/format checks.
+- Risks:
+  - The repo orchestrator must be enabled in `.mosaic/orchestrator/config.json`.
+  - Result JSON does not always embed worker output, so the runtime falls back to metadata-linked output files or a formatted result summary.
+- Verification:
+  - `npx tsc --noEmit --target es2022 --module nodenext --moduleResolution nodenext --skipLibCheck plugins/macp/src/macp-runtime.ts plugins/macp/src/index.ts`
+  - `pnpm prettier --write "plugins/macp/**/*.{ts,json,md}"`
+  - `pnpm format:check`
+  - `npx tsc --noEmit -p plugins/macp/tsconfig.json` still fails in this branch because `plugins/macp/tsconfig.json` extends a missing `packages/config/typescript/library.json` file and also pulls in pre-existing external OpenClaw type noise.

+# WP1: packages/forge — Forge Pipeline Package
+
+## Context
+
+Port the Forge progressive refinement pipeline from Python (~/src/mosaic-stack/forge/) to TypeScript as `packages/forge` in this monorepo. The pipeline markdown assets (stages, agents, personas, rails, gates, templates) are already copied to `packages/forge/pipeline/`. This task is the TypeScript implementation layer.
+
+**Board decisions that constrain this work:**
+
+- Abstract TaskExecutor interface — packages/forge must NOT hard-import packages/coord. Define an abstract interface; coord satisfies it.
+- Clean index.ts exports, no internal path leakage, no hardcoded paths
+- 85% test coverage on TS implementation files (markdown assets excluded)
+- Test strategy for non-deterministic AI orchestration: fixture-based integration tests
+- OpenBrain is OUT OF SCOPE
+- ESM only, zero Python
+
+**Dependencies available:**
+
+- `@mosaic/macp` (packages/macp) is built and provides: GateEntry, GateResult, Task types, credential resolution, gate running, event emission
+
+## Source Files (Python → TypeScript)
+
+### 1. types.ts
+
+Define all Forge-specific types:
+
+```typescript
+// Stage specification
+interface StageSpec {
+  number: string;
+  title: string;
+  dispatch: 'exec' | 'yolo' | 'pi';
+  type: 'research' | 'review' | 'coding' | 'deploy';
+  gate: string;
+  promptFile: string;
+  qualityGates: (string | GateEntry)[];
+}
+
+// Brief classification
+type BriefClass = 'strategic' | 'technical' | 'hotfix';
+type ClassSource = 'cli' | 'frontmatter' | 'auto';
+
+// Run manifest (persisted to disk)
+interface RunManifest {
+  runId: string;
+  brief: string;
+  codebase: string;
+  briefClass: BriefClass;
+  classSource: ClassSource;
+  forceBoard: boolean;
+  createdAt: string;
+  updatedAt: string;
+  currentStage: string;
+  status: 'in_progress' | 'completed' | 'failed' | 'interrupted' | 'rejected';
+  stages: Record<string, StageStatus>;
+}
+
+// Abstract task executor (decouples from packages/coord)
+interface TaskExecutor {
+  submitTask(task: ForgeTask): Promise<void>;
+  waitForCompletion(taskId: string, timeoutMs: number): Promise<TaskResult>;
+}
+
+// Persona override config
+interface ForgeConfig {
+  board?: {
+    additionalMembers?: string[];
+    skipMembers?: string[];
+  };
+  specialists?: {
+    alwaysInclude?: string[];
+  };
+}
+```
+
+### 2. constants.ts
+
+**Source:** Top of `~/src/mosaic-stack/forge/lib` (ALL_STAGES, LABELS, STAGE_SPECS equivalent) + `~/src/mosaic-stack/forge/pipeline/orchestrator/stage_adapter.py` (STAGE_TIMEOUTS)
+
+```typescript
+export const STAGE_SEQUENCE = [
+  '00-intake',
+  '00b-discovery',
+  '01-board',
+  '01b-brief-analyzer',
+  '02-planning-1',
+  '03-planning-2',
+  '04-planning-3',
+  '05-coding',
+  '06-review',
+  '07-remediate',
+  '08-test',
+  '09-deploy',
+];
+
+export const STAGE_TIMEOUTS: Record<string, number> = {
+  '00-intake': 120,
+  '00b-discovery': 300,
+  '01-board': 120,
+  '02-planning-1': 600,
+  // ... etc
+};
+
+export const STAGE_LABELS: Record<string, string> = {
+  '00-intake': 'INTAKE',
+  // ... etc
+};
+```
+
+Also: STRATEGIC_KEYWORDS, TECHNICAL_KEYWORDS for brief classification.
+
+### 3. brief-classifier.ts
+
+**Source:** `classify_brief()`, `parse_brief_frontmatter()`, `stages_for_class()` from `~/src/mosaic-stack/forge/lib`
+
+- Auto-classify brief by keyword analysis (strategic vs technical)
+- Parse YAML frontmatter for explicit `class:` field
+- CLI flag override
+- Return stage list based on classification (strategic = full pipeline, technical = skip board, hotfix = skip board + brief analyzer)
+
+### 4. stage-adapter.ts
+
+**Source:** `~/src/mosaic-stack/forge/pipeline/orchestrator/stage_adapter.py`
+
+- `mapStageToTask()`: Convert a Forge stage into a task compatible with TaskExecutor
+- Stage briefs written to `{runDir}/{stageName}/brief.md`
+- Result paths at `{runDir}/{stageName}/result.json`
+- Previous results read from disk at runtime (not baked into brief)
+- Per-stage timeouts from STAGE_TIMEOUTS
+- depends_on chain built from stage sequence
+
+### 5. board-tasks.ts
+
+**Source:** `~/src/mosaic-stack/forge/pipeline/orchestrator/board_tasks.py`
+
+- `loadBoardPersonas()`: Read all .md files from `pipeline/agents/board/`
+- `generateBoardTasks()`: One task per persona + synthesis task
+- Synthesis depends on all persona tasks with `depends_on_policy: 'all_terminal'`
+- Persona briefs include role description + brief under review
+- Synthesis script merges independent reviews into board memo
+
+### 6. pipeline-runner.ts
+
+**Source:** `~/src/mosaic-stack/forge/pipeline/orchestrator/pipeline_runner.py` + `~/src/mosaic-stack/forge/lib` (cmd_run, cmd_resume, cmd_status)
+
+- `runPipeline(briefPath, projectRoot, options)`: Full pipeline execution
+- Creates run directory at `{projectRoot}/.forge/runs/{runId}/`
+- Generates tasks for all stages, submits to TaskExecutor
+- Tracks manifest.json with stage statuses
+- `resumePipeline(runDir)`: Pick up from last incomplete stage
+- `getPipelineStatus(runDir)`: Read manifest and report
+
+**Key difference from Python:** Run output goes to PROJECT-scoped `.forge/runs/`, not inside the Forge package.
+
+### 7. Persona Override System (NEW — not in Python)
+
+- Base personas read from `packages/forge/pipeline/agents/`
+- Project overrides read from `{projectRoot}/.forge/personas/{role}.md`
+- Merge strategy: project persona content APPENDED to base persona (not replaced)
+- Board composition configurable via `{projectRoot}/.forge/config.yaml`
+- If no project config exists, use defaults (all base personas, no overrides)

+
+```json
+{
+  "name": "@mosaic/forge",
+  "version": "0.0.1",
+  "type": "module",
+  "exports": {
+    ".": "./src/index.ts"
+  },

+  },
+  "devDependencies": {
+    "vitest": "workspace:*",
+    "typescript": "workspace:*"
+  }
+}
+```
+
+Only dependency: @mosaic/macp (for gate types, event emission).
+
+## Test Strategy (Board requirement)
+
+**Deterministic code (brief-classifier, stage-adapter, board-tasks, persona-loader, constants):**
+
+- Standard unit tests with known inputs/outputs
+- 100% of classification logic, stage mapping, persona loading covered
+
+**Non-deterministic code (pipeline-runner):**
+
+- Fixture-based integration tests using a mock TaskExecutor
+- Mock executor returns pre-recorded results for each stage
+- Tests verify: manifest progression, stage ordering, dependency enforcement, resume behavior, error handling
+- NO real AI calls in tests
+
+**Markdown assets:** Excluded from coverage measurement (configure vitest to exclude `pipeline/` directory).
+
+## ESM Requirements
+
+- `"type": "module"` in package.json
+- NodeNext module resolution in tsconfig
+- `.js` extensions in all imports
+- No CommonJS
+
+## Key Design: Abstract TaskExecutor
+
+```typescript
+// In packages/forge/src/types.ts
+export interface TaskExecutor {
+  submitTask(task: ForgeTask): Promise<void>;
+  waitForCompletion(taskId: string, timeoutMs: number): Promise<TaskResult>;
+  getTaskStatus(taskId: string): Promise<TaskStatus>;
+}
+
+// In packages/coord (or wherever the concrete impl lives)
+export class CoordTaskExecutor implements TaskExecutor {
+  // ... uses packages/coord runner
+}
+```
+
+This means packages/forge can be tested with a mock executor and deployed with any backend.
+
+## Asset Resolution
+
+Pipeline markdown assets (stages, personas, rails) must be resolved relative to the package installation, NOT hardcoded paths:
+
+```typescript
+// Use import.meta.url to find package root
+const PACKAGE_ROOT = new URL('..', import.meta.url).pathname;
+const PIPELINE_DIR = path.join(PACKAGE_ROOT, 'pipeline');
+```
+
+Project-level overrides resolved relative to projectRoot parameter.

+# WP2: packages/macp — MACP Protocol Package
+
+## Context
+
+Port the MACP protocol layer from Python (in ~/src/mosaic-stack/tools/macp/) to TypeScript as `packages/macp` in this monorepo. This package provides the foundational protocol types, quality gate execution, credential resolution, and event system that `packages/coord` and `plugins/macp` depend on.
+
+**Board decisions that constrain this work:**
+
+- No Python in the new repo — everything rewrites to TypeScript
+- OpenBrain learning capture/recall is OUT OF SCOPE (deferred to future brief)
+- 85% test coverage on TS implementation files
+- Credential resolver behavior must be captured as test fixtures BEFORE rewrite
+- Clean index.ts exports, no internal path leakage
+
+## Source Files (Python → TypeScript)
+
+### 1. credential-resolver.ts
+
+**Source:** `~/src/mosaic-stack/tools/macp/dispatcher/credential_resolver.py`
+
+Resolution order (MUST preserve exactly):
+
+1. Mosaic credential files (`~/.config/mosaic/credentials/{provider}.env`)
+2. OpenClaw config (`~/.openclaw/openclaw.json`) — env block + models.providers.{provider}.apiKey
+3. Ambient environment variables
+4. CredentialError (failure)
+
+Key behaviors to preserve:
+
+- Provider registry: anthropic, openai, zai → env var names + credential file paths + OC config paths
+- Dotenv parser: handles single/double quotes, comments, blank lines
+- JSON5 stripping: placeholder-extraction approach (NOT naive regex) — protects URLs and timestamps inside string values
+- OC config permission check: warn on world-readable, skip if wrong owner
+- Redacted marker detection: `__OPENCLAW_REDACTED__` values skipped
+- Task-level override via `credentials.provider_key_env`
+
+### 2. gate-runner.ts
+
+**Source:** `~/src/mosaic-stack/tools/macp/controller/gate_runner.py`
+
+Three gate types:
+
+- `mechanical`: shell command, pass = exit code 0
+- `ai-review`: shell command producing JSON, parse findings, fail on blockers
+- `ci-pipeline`: placeholder (always passes for now)
+
+Key behaviors:
+
+- `normalize_gate()`: accepts string or dict, normalizes to gate entry
+- `run_gate()`: executes single gate, returns result with pass/fail
+- `run_gates()`: executes all gates, emits events, returns (all_passed, results)
+- AI review parsing: `_count_ai_findings()` reads stats.blockers or findings[].severity
+- `fail_on` modes: "blocker" (default) or "any"
+
+### 3. event-emitter.ts
+
+**Source:** `~/src/mosaic-stack/tools/macp/controller/gate_runner.py` (emit_event, append_event functions) + `~/src/mosaic-stack/tools/macp/events/`
+
+- Append structured events to ndjson file
+- Event types: task.assigned, task.started, task.completed, task.failed, task.escalated, task.gated, task.retry.scheduled, rail.check.started, rail.check.passed, rail.check.failed
+- Each event: event_id (uuid), event_type, task_id, status, timestamp, source, message, metadata
+
+### 4. types.ts
+
+**Source:** `~/src/mosaic-stack/tools/macp/protocol/task.schema.json`
+
+TypeScript types for:
+
+- Task (id, title, status, dispatch, runtime, depends_on, depends_on_policy, quality_gates, timeout_seconds, metadata, etc.)
+- Event (event_id, event_type, task_id, status, timestamp, source, message, metadata)
+- GateResult (command, exit_code, type, passed, output, findings, blockers)
+- TaskResult (task_id, status, completed_at, exit_code, gate_results, files_changed, etc.)
+- CredentialError, ProviderRegistry
+
+### 5. schemas/ (copy)
+
+Copy `~/src/mosaic-stack/tools/macp/protocol/task.schema.json` as-is.

+
+Zero external dependencies. Uses node:fs, node:path, node:child_process, node:crypto only.
+
+## Test Requirements
+
+Port ALL existing Python tests as TypeScript equivalents:
+
+- `test_resolve_from_file` → credential file resolution
+- `test_resolve_from_ambient` → ambient env resolution
+- `test_resolve_from_oc_config_env_block` → OC config env block
+- `test_resolve_from_oc_config_provider_apikey` → OC config provider
+- `test_oc_config_precedence` → mosaic file wins over OC config
+- `test_oc_config_missing_file` → graceful fallback
+- `test_json5_strip` → structural transforms
+- `test_json5_strip_urls_and_timestamps` → URLs/timestamps survive
+- `test_redacted_values_skipped` → redacted marker detection
+- `test_oc_config_permission_warning` → file permission check
+- `test_resolve_missing_raises` → CredentialError thrown
+- Gate runner: mechanical pass/fail, AI review parsing, ci-pipeline placeholder
+- Event emitter: append to ndjson, event structure validation
+
+## ESM Requirements
+
+- `"type": "module"` in package.json
+- NodeNext module resolution in tsconfig
+- `.js` extensions in all imports
+- No CommonJS (`require`, `module.exports`)
+
+## Integration Points
+
+After this package is built:
+
+- `packages/coord` should import `@mosaic/macp` for event emission and gate types
+- `plugins/macp` should import `@mosaic/macp` for credential resolution and protocol types

+# WP3: plugins/mosaic-framework — OC Rails Injection Plugin
+
+## Context
+
+Port the OpenClaw framework plugin from ~/src/mosaic-stack/oc-plugins/mosaic-framework/ to `plugins/mosaic-framework` in this monorepo. This plugin injects Mosaic framework contracts (rails, completion gates, worktree requirements) into every OpenClaw agent session.
+
+**This is SEPARATE from plugins/macp:**
+
+- `mosaic-framework` = passive enforcement — injects rails into all OC sessions
+- `macp` = active runtime — provides ACP backend for MACP task execution
+
+## Source Files
+
+**Source:** `~/src/mosaic-stack/oc-plugins/mosaic-framework/`
+
+- `index.ts` — plugin hooks (before_agent_start, subagent_spawning)
+- `openclaw.plugin.json` — plugin manifest
+- `package.json`
+
+## What It Does
+
+### For OC native agents (before_agent_start hook):
+
+- Injects Mosaic global hard rules via `appendSystemContext`
+- Completion gates: code review ✓ | security review ✓ | tests GREEN ✓ | CI green ✓
+- Worker completion protocol: open PR → fire system event → EXIT — never merge
+- Worktree requirement: `~/src/{repo}-worktrees/{task-slug}`, never `/tmp`
+- Injects dynamic mission state via `prependContext` (reads from project's `.mosaic/orchestrator/mission.json`)
+
+### For ACP coding workers (subagent_spawning hook):
+
+- Writes `~/.codex/instructions.md` or `~/.claude/CLAUDE.md` BEFORE the process starts
+- Full runtime contract: mandatory load order, hard gates, mode declaration
+- Global framework rules + worktree + completion gate requirements
+
+## Implementation
+
+Port the TypeScript source, updating hardcoded paths to be configurable. The OC plugin SDK imports should reference the installed OpenClaw location dynamically (not hardcoded `/home/jarvis/` paths like the OLD version).
+
+**Structure:**
+
+```
+plugins/mosaic-framework/
+├── src/
+│   └── index.ts
+├── openclaw.plugin.json
+├── package.json
+└── tsconfig.json
+```
+
+## Key Constraint
+
+The plugin SDK imports in the OLD version use absolute paths:
+
+```typescript
+import type { OpenClawPluginApi } from '/home/jarvis/.npm-global/lib/node_modules/openclaw/dist/plugin-sdk/index.js';
+```
+
+This must be resolved dynamically or via a peer dependency. Check how `plugins/macp` handles this in the new repo and follow the same pattern.
+
+## Tests
+
+Minimal — plugin hooks are integration-tested against OC runtime. Unit test the context string builders and config resolution.

+# Authentication & Authorization Guide
+
+## Before Starting
+
+1. Check assigned issue: `~/.config/mosaic/tools/git/issue-list.sh -a @me`
+2. Review existing auth implementation in codebase
+3. Review Vault secrets structure: `docs/vault-secrets-structure.md`
+
+## Authentication Patterns
+
+### JWT (JSON Web Tokens)
+
+```
+Vault Path: secret-{env}/backend-api/jwt/signing-key
+Fields: key, algorithm, expiry_seconds
+```
+
+**Best Practices:**
+
+- Use RS256 or ES256 (asymmetric) for distributed systems
+- Use HS256 (symmetric) only for single-service auth
+- Set reasonable expiry (15min-1hr for access tokens)
+- Include minimal claims (sub, exp, iat, roles)
+- Never store sensitive data in JWT payload
+
+### Session-Based
+
+```
+Vault Path: secret-{env}/{service}/session/secret
+Fields: secret, cookie_name, max_age
+```
+
+**Best Practices:**
+
+- Use secure, httpOnly, sameSite cookies
+- Regenerate session ID on privilege change
+- Implement session timeout
+- Store sessions server-side (Redis/database)
+
+### OAuth2/OIDC
+
+```
+Vault Paths:
+- secret-{env}/{service}/oauth/{provider}/client_id
+- secret-{env}/{service}/oauth/{provider}/client_secret
+```
+
+**Best Practices:**
+
+- Use PKCE for public clients
+- Validate state parameter
+- Verify token signatures
+- Check issuer and audience claims
+
+## Authorization Patterns
+
+### Role-Based Access Control (RBAC)
+
+```python
+# Example middleware
+def require_role(roles: list):
+    def decorator(handler):
+        def wrapper(request):
+            user_roles = get_user_roles(request.user_id)
+            if not any(role in user_roles for role in roles):
+                raise ForbiddenError()
+            return handler(request)
+        return wrapper
+    return decorator
+
+@require_role(['admin', 'moderator'])
+def delete_user(request):
+    pass
+```
+
+### Permission-Based
+
+```python
+# Check specific permissions
+def check_permission(user_id, resource, action):
+    permissions = get_user_permissions(user_id)
+    return f"{resource}:{action}" in permissions
+```
+
+## Security Requirements
+
+### Password Handling
+
+- Use bcrypt, scrypt, or Argon2 for hashing
+- Minimum 12 character passwords
+- Check against breached password lists
+- Implement account lockout after failed attempts
+
+### Token Security
+
+- Rotate secrets regularly
+- Implement token revocation
+- Use short-lived access tokens with refresh tokens
+- Store refresh tokens securely (httpOnly cookies or encrypted storage)
+
+### Multi-Factor Authentication
+
+- Support TOTP (Google Authenticator compatible)
+- Consider WebAuthn for passwordless
+- Require MFA for sensitive operations
+
+## Testing Authentication
+
+### Test Cases Required
+
+```python
+class TestAuthentication:
+    def test_login_success_returns_token(self):
+        pass
+    def test_login_failure_returns_401(self):
+        pass
+    def test_invalid_token_returns_401(self):
+        pass
+    def test_expired_token_returns_401(self):
+        pass
+    def test_missing_token_returns_401(self):
+        pass
+    def test_insufficient_permissions_returns_403(self):
+        pass
+    def test_token_refresh_works(self):
+        pass
+    def test_logout_invalidates_token(self):
+        pass
+```
+
+## Authentik SSO Administration
+
+Authentik is the identity provider for the Mosaic Stack. Use the Authentik tool suite for administration.
+
+### Tool Suite
+
+```bash
+# System health
+~/.config/mosaic/tools/authentik/admin-status.sh
+
+# User management
+~/.config/mosaic/tools/authentik/user-list.sh
+~/.config/mosaic/tools/authentik/user-create.sh -u <username> -n <name> -e <email>
+
+# Group and app management
+~/.config/mosaic/tools/authentik/group-list.sh
+~/.config/mosaic/tools/authentik/app-list.sh
+~/.config/mosaic/tools/authentik/flow-list.sh
+```
+
+### Registering an OAuth Application
+
+1. Create an OAuth2 provider in Authentik admin (Applications > Providers)
+2. Create an application linked to the provider (Applications > Applications)
+3. Configure redirect URIs for the application
+4. Store client_id and client_secret in Vault: `secret-{env}/{service}/oauth/authentik/`
+5. Verify with: `~/.config/mosaic/tools/authentik/app-list.sh`
+
+### API Reference
+
+- Base URL: `https://auth.diversecanvas.com`
+- API prefix: `/api/v3/`
+- OpenAPI schema: `/api/v3/schema/`
+- Auth: Bearer token (obtained via `auth-token.sh`)
+
+## Common Vulnerabilities to Avoid
+
+1. **Broken Authentication**
+   - Weak password requirements
+   - Missing brute-force protection
+   - Session fixation
+
+2. **Broken Access Control**
+   - Missing authorization checks
+   - IDOR (Insecure Direct Object Reference)
+   - Privilege escalation
+
+3. **Security Misconfiguration**
+   - Default credentials
+   - Verbose error messages
+   - Missing security headers
+
+## Commit Format
+
+```
+feat(#89): Implement JWT authentication
+
+- Add /auth/login and /auth/refresh endpoints
+- Implement token validation middleware
+- Configure 15min access token expiry

+# Backend Development Guide
+
+## Before Starting
+
+1. Check assigned issue: `~/.config/mosaic/tools/git/issue-list.sh -a @me`
+2. Create scratchpad: `docs/scratchpads/{issue-number}-{short-name}.md`
+3. Review API contracts and database schema
+
+## Development Standards
+
+### API Design
+
+- Follow RESTful conventions (or GraphQL patterns if applicable)
+- Use consistent endpoint naming: `/api/v1/resource-name`
+- Return appropriate HTTP status codes
+- Include pagination for list endpoints
+- Document all endpoints (OpenAPI/Swagger preferred)
+
+### Database
+
+- Write migrations for schema changes
+- Use parameterized queries (prevent SQL injection)
+- Index frequently queried columns
+- Document relationships and constraints
+
+### Error Handling
+
+- Return structured error responses
+- Log errors with context (request ID, user ID if applicable)
+- Never expose internal errors to clients
+- Use appropriate error codes
+
+```json
+{
+  "error": {
+    "code": "VALIDATION_ERROR",
+    "message": "User-friendly message",
+    "details": []
+  }
+}
+```
+
+### Security
+
+- Validate all input at API boundaries
+- Implement rate limiting on public endpoints
+- Use secrets from Vault (see `docs/vault-secrets-structure.md`)
+- Never log sensitive data (passwords, tokens, PII)
+- Follow OWASP guidelines
+
+### Authentication/Authorization
+
+- Use project's established auth pattern
+- Validate tokens on every request
+- Check permissions before operations
+- See `~/.config/mosaic/guides/AUTHENTICATION.md` for details
+
+## Testing Requirements (TDD)
+
+1. Write tests BEFORE implementation
+2. Minimum 85% coverage
+3. Test categories:
+   - Unit tests for business logic
+   - Integration tests for API endpoints
+   - Database tests with transactions/rollback
+
+### Test Patterns
+
+```python
+# API test example structure
+class TestResourceEndpoint:
+    def test_create_returns_201(self):
+        pass
+    def test_create_validates_input(self):
+        pass
+    def test_get_returns_404_for_missing(self):
+        pass
+    def test_requires_authentication(self):
+        pass
+```
+
+## Code Style
+
+- Follow Google Style Guide for your language
+- **TypeScript: Follow `~/.config/mosaic/guides/TYPESCRIPT.md` — MANDATORY**
+- Use linter/formatter from project configuration
+- Keep functions focused and small
+- Document complex business logic
+
+### TypeScript Quick Rules (see TYPESCRIPT.md for full guide)
+
+- **NO `any`** — define explicit types always
+- **NO lazy `unknown`** — only for error catches and external data with validation
+- **Explicit return types** on all exported functions
+- **Explicit parameter types** always
+- **DTO files are REQUIRED** for module/API boundaries (`*.dto.ts`)
+- **Interface for DTOs** — never inline object types
+- **Typed errors** — use custom error classes
+
+## Performance
+
+- Use database connection pooling
+- Implement caching where appropriate
+- Profile slow endpoints
+- Use async operations for I/O
+
+## Commit Format
+
+```
+feat(#45): Add user registration endpoint
+
+- POST /api/v1/users for registration
+- Email validation and uniqueness check
+- Password hashing with bcrypt
+
+Fixes #45

+# Project Bootstrap Guide
+
+> Load this guide when setting up a new project for AI-assisted development.
+
+## Overview
+
+This guide covers how to bootstrap a project so AI agents (Claude, Codex, etc.) can work on it effectively. Proper bootstrapping ensures:
+
+1. Agents understand the project structure and conventions
+2. Orchestration works correctly with quality gates
+3. Independent code review and security review are configured
+4. Issue tracking is consistent across projects
+5. Documentation standards and API contracts are enforced from day one
+6. PRD requirements are established before coding begins
+7. Branching/merging is consistent: `branch -> main` via PR with squash-only merges
+8. Steered-autonomy execution is enabled so agents can run end-to-end with escalation-only human intervention
+
+## Quick Start
+
+```bash
+# Automated bootstrap (recommended)
+~/.config/mosaic/tools/bootstrap/init-project.sh \
+  --name "my-project" \
+  --type "nestjs-nextjs" \
+  --repo "https://git.mosaicstack.dev/owner/repo"
+
+# Or manually using templates
+export PROJECT_NAME="My Project"
+export PROJECT_DESCRIPTION="What this project does"
+export TASK_PREFIX="MP"
+envsubst < ~/.config/mosaic/templates/agent/AGENTS.md.template > AGENTS.md
+envsubst < ~/.config/mosaic/templates/agent/CLAUDE.md.template > CLAUDE.md
+```
+
+---
+
+## Step 0: Enforce Sequential-Thinking MCP (Hard Requirement)
+
+`sequential-thinking` MCP must be installed and configured before project bootstrapping.
+
+```bash
+# Auto-configure sequential-thinking MCP for installed runtimes
+~/.config/mosaic/bin/mosaic-ensure-sequential-thinking
+
+# Verification-only check
+~/.config/mosaic/bin/mosaic-ensure-sequential-thinking --check
+```
+
+If this step fails, STOP and remediate Mosaic runtime configuration before continuing.
+
+---
+
+## Step 1: Detect Project Type
+
+Check what files exist in the project root to determine the type:
+
+| File Present                                            | Project Type              | Template                  |
+| ------------------------------------------------------- | ------------------------- | ------------------------- |
+| `package.json` + `pnpm-workspace.yaml` + NestJS+Next.js | NestJS + Next.js Monorepo | `projects/nestjs-nextjs/` |
+| `pyproject.toml` + `manage.py`                          | Django                    | `projects/django/`        |
+| `pyproject.toml` (no Django)                            | Python (generic)          | Generic template          |
+| `package.json` (no monorepo)                            | Node.js (generic)         | Generic template          |
+| Other                                                   | Generic                   | Generic template          |
+
+```bash
+# Auto-detect project type
+detect_project_type() {
+  if [[ -f "pnpm-workspace.yaml" ]] && [[ -f "turbo.json" ]]; then
+    # Check for NestJS + Next.js
+    if grep -q "nestjs" package.json 2>/dev/null && grep -q "next" package.json 2>/dev/null; then
+      echo "nestjs-nextjs"
+      return
+    fi
+  fi
+  if [[ -f "manage.py" ]] && [[ -f "pyproject.toml" ]]; then
+    echo "django"
+    return
+  fi
+  if [[ -f "pyproject.toml" ]]; then
+    echo "python"
+    return
+  fi
+  if [[ -f "package.json" ]]; then
+    echo "nodejs"
+    return
+  fi
+  echo "generic"
+}
+```
+
+---
+
+## Step 2: Create AGENTS.md (Primary Project Contract)
+
+`AGENTS.md` is the primary project-level contract for all agent runtimes.
+It defines project-specific requirements, quality gates, patterns, and testing expectations.
+
+### Using a Tech-Stack Template
+
+```bash
+# Set variables
+export PROJECT_NAME="My Project"
+export PROJECT_DESCRIPTION="Multi-tenant SaaS platform"
+export PROJECT_DIR="my-project"
+export REPO_URL="https://git.mosaicstack.dev/owner/repo"
+export TASK_PREFIX="MP"
+
+# Use tech-stack-specific template if available
+TYPE=$(detect_project_type)
+TEMPLATE_DIR="$HOME/.config/mosaic/templates/agent/projects/$TYPE"
+
+if [[ -d "$TEMPLATE_DIR" ]]; then
+  envsubst < "$TEMPLATE_DIR/AGENTS.md.template" > AGENTS.md
+else
+  envsubst < "$HOME/.config/mosaic/templates/agent/AGENTS.md.template" > AGENTS.md
+fi
+```
+
+### Using the Generic Template
+
+```bash
+# Set all required variables
+export PROJECT_NAME="My Project"
+export PROJECT_DESCRIPTION="What this project does"
+export REPO_URL="https://git.mosaicstack.dev/owner/repo"
+export PROJECT_DIR="my-project"
+export SOURCE_DIR="src"
+export CONFIG_FILES="pyproject.toml / package.json"
+export FRONTEND_STACK="N/A"
+export BACKEND_STACK="Python / FastAPI"
+export DATABASE_STACK="PostgreSQL"
+export TESTING_STACK="pytest"
+export DEPLOYMENT_STACK="Docker"
+export BUILD_COMMAND="pip install -e ."
+export TEST_COMMAND="pytest tests/"
+export LINT_COMMAND="ruff check ."
+export TYPECHECK_COMMAND="mypy ."
+export QUALITY_GATES="ruff check . && mypy . && pytest tests/"
+
+envsubst < ~/.config/mosaic/templates/agent/AGENTS.md.template > AGENTS.md
+```
+
+### Required Sections
+
+Every AGENTS.md should contain:
+
+1. **Project description** — One-line summary
+2. **Quality gates** — Commands that must pass
+3. **Codebase patterns** — Reusable implementation rules
+4. **Common gotchas** — Non-obvious constraints
+5. **Testing approaches** — Project-specific test strategy
+6. **Testing policy** — Situational-first validation and risk-based TDD
+7. **Orchestrator integration** — Task prefix, worker checklist
+8. **Documentation contract** — Required documentation gates and update expectations
+9. **PRD requirement** — `docs/PRD.md` or `docs/PRD.json` required before coding
+
+---
+
+## Step 3: Create Runtime Context File (Runtime-Specific)
+
+Runtime context files are runtime adapters. They are not the primary project contract.
+Use `CLAUDE.md` for Claude runtime compatibility. Use other runtime adapters as required by your environment.
+
+Claude runtime mandate (HARD RULE):
+
+- `CLAUDE.md` MUST explicitly instruct Claude agents to read and use `AGENTS.md`.
+- `CLAUDE.md` MUST treat `AGENTS.md` as the authoritative project-level contract.
+- If `AGENTS.md` and runtime wording conflict, `AGENTS.md` project rules win.
+
+```bash
+TYPE=$(detect_project_type)
+TEMPLATE_DIR="$HOME/.config/mosaic/templates/agent/projects/$TYPE"
+
+if [[ -d "$TEMPLATE_DIR" ]]; then
+  envsubst < "$TEMPLATE_DIR/CLAUDE.md.template" > CLAUDE.md
+else
+  envsubst < "$HOME/.config/mosaic/templates/agent/CLAUDE.md.template" > CLAUDE.md
+fi
+```
+
+### Required Runtime Sections
+
+Every runtime context file should contain:
+
+1. **AGENTS handoff rule** — Runtime MUST direct agents to read/use `AGENTS.md`
+2. **Conditional documentation loading** — Required guide loading map
+3. **Technology stack** — Runtime-facing architecture summary
+4. **Repository structure** — Important paths
+5. **Development workflow** — Build/test/lint/typecheck commands
+6. **Issue tracking** — Issue and commit conventions
+7. **Code review** — Required review process
+8. **Runtime notes** — Runtime-specific behavior references
+9. **Branch and merge policy** — Trunk workflow (`branch -> main` via PR, squash-only)
+10. **Autonomy and escalation policy** — Agent owns coding/review/PR/release/deploy lifecycle
+
+---
+
+## Step 4: Create Directory Structure
+
+```bash
+# Create standard directories
+mkdir -p docs/scratchpads
+mkdir -p docs/templates
+mkdir -p docs/reports/qa-automation/pending
+mkdir -p docs/reports/qa-automation/in-progress
+mkdir -p docs/reports/qa-automation/done
+mkdir -p docs/reports/qa-automation/escalated
+mkdir -p docs/reports/deferred
+mkdir -p docs/tasks
+mkdir -p docs/releases
+mkdir -p docs/USER-GUIDE docs/ADMIN-GUIDE docs/DEVELOPER-GUIDE docs/API
+
+# Documentation baseline files
+touch docs/USER-GUIDE/README.md
+touch docs/ADMIN-GUIDE/README.md
+touch docs/DEVELOPER-GUIDE/README.md
+touch docs/API/OPENAPI.yaml
+touch docs/API/ENDPOINTS.md
+touch docs/SITEMAP.md
+
+# PRD baseline file (requirements source before coding)
+cp ~/.config/mosaic/templates/docs/PRD.md.template docs/PRD.md
+
+# TASKS baseline file (canonical tracking)
+cp ~/.config/mosaic/templates/docs/TASKS.md.template docs/TASKS.md
+
+# Deployment baseline file (target/platform/runbook)
+touch docs/DEPLOYMENT.md
+```
+
+Documentation root hygiene (HARD RULE):
+
+- Keep `docs/` root clean.
+- Store reports in `docs/reports/`, archived task artifacts in `docs/tasks/`, releases in `docs/releases/`, and scratchpads in `docs/scratchpads/`.
+- Do not place ad-hoc report files directly under `docs/`.
+
+---
+
+## Step 5: Initialize Repository Labels & Milestones
+
+```bash
+# Use the init script
+~/.config/mosaic/tools/bootstrap/init-repo-labels.sh
+
+# Or manually create standard labels
+~/.config/mosaic/tools/git/issue-create.sh  # (labels are created on first use)
+```
+
+### Standard Labels
+
+| Label           | Color     | Purpose                                |
+| --------------- | --------- | -------------------------------------- |
+| `epic`          | `#3E4B9E` | Large feature spanning multiple issues |
+| `feature`       | `#0E8A16` | New functionality                      |
+| `bug`           | `#D73A4A` | Defect fix                             |
+| `task`          | `#0075CA` | General work item                      |
+| `documentation` | `#0075CA` | Documentation updates                  |
+| `security`      | `#B60205` | Security-related                       |
+| `breaking`      | `#D93F0B` | Breaking change                        |
+
+### Initial Milestone (Hard Rule)
+
+Create the first pre-MVP milestone at `0.0.1`.
+Reserve `0.1.0` for the MVP release milestone.
+
+```bash
+~/.config/mosaic/tools/git/milestone-create.sh -t "0.0.1" -d "Pre-MVP - Foundation Sprint"
+
+# Create when MVP scope is complete and release-ready:
+~/.config/mosaic/tools/git/milestone-create.sh -t "0.1.0" -d "MVP - Minimum Viable Product"
+```
+
+---
+
+## Step 5b: Configure Main Branch Protection (Hard Rule)
+
+Apply equivalent settings in Gitea, GitHub, or GitLab:
+
+1. Protect `main` from direct pushes.
+2. Require pull requests to merge into `main`.
+3. Require required CI/status checks to pass before merge.
+4. Require code review approval before merge.
+5. Allow **squash merge only** for PRs into `main` (disable merge commits and rebase merges for `main`).
+
+This enforces one merge strategy across human and agent workflows.
+
+---
+
+## Step 6: Set Up CI/CD Review Pipeline
+
+### Woodpecker CI
+
+```bash
+# Copy Codex review pipeline
+mkdir -p .woodpecker/schemas
+cp ~/.config/mosaic/tools/codex/woodpecker/codex-review.yml .woodpecker/
+cp ~/.config/mosaic/tools/codex/schemas/*.json .woodpecker/schemas/
+
+# Add codex_api_key secret to Woodpecker CI dashboard
+```
+
+### GitHub Actions
+
+For GitHub repos, use the official Codex GitHub Action instead:
+
+```yaml
+# .github/workflows/codex-review.yml
+uses: openai/codex-action@v1
+```
+
+### Python Package Publishing (Gitea PyPI)
+
+If the project publishes Python packages, use Gitea's PyPI registry.
+
+```bash
+# Build and publish
+python -m pip install --upgrade build twine
+python -m build
+python -m twine upload \
+  --repository-url "https://GITEA_HOST/api/packages/ORG/pypi" \
+  --username "$GITEA_USERNAME" \
+  --password "$GITEA_TOKEN" \
+  dist/*
+```
+
+Use the same `gitea_username` and `gitea_token` CI secrets used for container and npm publishing.
+
+---
+
+## Step 7: Verify Bootstrap
+
+After bootstrapping, verify everything works:
+
+```bash
+# Check files exist
+ls AGENTS.md docs/scratchpads/
+ls docs/reports/qa-automation/pending docs/reports/deferred docs/tasks docs/releases
+ls docs/USER-GUIDE/README.md docs/ADMIN-GUIDE/README.md docs/DEVELOPER-GUIDE/README.md
+ls docs/API/OPENAPI.yaml docs/API/ENDPOINTS.md docs/SITEMAP.md
+ls docs/PRD.md
+ls docs/TASKS.md
+
+# Verify AGENTS.md has required sections
+grep -c "Quality Gates" AGENTS.md
+grep -c "Orchestrator Integration" AGENTS.md
+grep -c "Testing Approaches" AGENTS.md
+grep -c "Testing Policy" AGENTS.md
+grep -c "Documentation Contract" AGENTS.md
+grep -c "PRD Requirement" AGENTS.md
+
+# Verify runtime context file has required sections
+if [[ -f CLAUDE.md ]]; then
+  grep -c "AGENTS.md" CLAUDE.md
+  grep -c "Conditional Documentation Loading" CLAUDE.md
+  grep -c "Technology Stack" CLAUDE.md
+  grep -c "Code Review" CLAUDE.md
+elif [[ -f RUNTIME.md ]]; then
+  grep -c "Conditional Documentation Loading" RUNTIME.md
+  grep -c "Technology Stack" RUNTIME.md
+  grep -c "Code Review" RUNTIME.md
+else
+  echo "Missing runtime context file (CLAUDE.md or RUNTIME.md)" >&2
+  exit 1
+fi
+
+# Run quality gates from AGENTS.md
+# (execute the command block under "Quality Gates")
+
+# Test Codex review (if configured)
+~/.config/mosaic/tools/codex/codex-code-review.sh --help
+
+# Verify sequential-thinking MCP remains configured
+~/.config/mosaic/bin/mosaic-ensure-sequential-thinking --check
+```

+# Code Review Guide
+
+## Hard Requirement
+
+If an agent modifies source code, code review is REQUIRED before completion.
+Do not mark code-change tasks done until review is completed and blockers are resolved or explicitly tracked.
+If code/config/API contract/auth behavior changed and required docs are missing, this is a BLOCKER.
+If tests pass but acceptance criteria are not verified by situational evidence, this is a BLOCKER.
+If implementation diverges from `docs/PRD.md` or `docs/PRD.json` without PRD updates, this is a BLOCKER.
+
+Merge strategy enforcement (HARD RULE):
+
+- PR target for delivery is `main`.
+- Direct pushes to `main` are prohibited.
+- Merge to `main` MUST be squash-only.
+- Use `~/.config/mosaic/tools/git/pr-merge.sh -n {PR_NUMBER} -m squash` (or PowerShell equivalent).
+
+## Review Checklist
+
+### 1. Correctness
+
+- [ ] Code does what the issue/PR description says
+- [ ] Code aligns with active PRD requirements
+- [ ] Acceptance criteria are mapped to concrete verification evidence
+- [ ] Edge cases are handled
+- [ ] Error conditions are managed properly
+- [ ] No obvious bugs or logic errors
+
+### 2. Security
+
+- [ ] No hardcoded secrets or credentials
+- [ ] Input validation at boundaries
+- [ ] SQL injection prevention (parameterized queries)
+- [ ] XSS prevention (output encoding)
+- [ ] Authentication/authorization checks present
+- [ ] Sensitive data not logged
+- [ ] Secrets follow Vault structure (see `docs/vault-secrets-structure.md`)
+
+### 2a. OWASP Coverage (Required)
+
+- [ ] OWASP Top 10 categories were reviewed for change impact
+- [ ] Access control checks verified on protected actions
+- [ ] Cryptographic handling validated (keys, hashing, TLS assumptions)
+- [ ] Injection risks reviewed for all untrusted inputs
+- [ ] Security misconfiguration risks reviewed (headers, CORS, defaults)
+- [ ] Dependency/component risk reviewed (known vulnerable components)
+- [ ] Authentication/session flows reviewed for failure paths
+- [ ] Logging/monitoring preserves detection without leaking sensitive data
+
+### 3. Testing
+
+- [ ] Tests exist for new functionality
+- [ ] Tests cover happy path AND error cases
+- [ ] Situational tests cover all impacted change surfaces (primary gate)
+- [ ] Tests validate required behavior/outcomes, not only internal implementation details
+- [ ] TDD was applied when required by `~/.config/mosaic/guides/QA-TESTING.md`
+- [ ] Coverage meets 85% minimum
+- [ ] Tests are readable and maintainable
+- [ ] No flaky tests introduced
+
+### 4. Code Quality
+
+- [ ] Follows Google Style Guide for the language
+- [ ] Functions are focused and reasonably sized
+- [ ] No unnecessary complexity
+- [ ] DRY - no significant duplication
+- [ ] Clear naming for variables and functions
+- [ ] No dead code or commented-out code
+
+### 4a. TypeScript Strict Typing (see `TYPESCRIPT.md`)
+
+- [ ] **NO `any` types** — explicit types required everywhere
+- [ ] **NO lazy `unknown`** — only for error catches with immediate narrowing
+- [ ] **Explicit return types** on all exported/public functions
+- [ ] **Explicit parameter types** — never implicit any
+- [ ] **No type assertions** (`as Type`) — use type guards instead
+- [ ] **No non-null assertions** (`!`) — use proper null handling
+- [ ] **Interfaces for objects** — not inline types
+- [ ] **Discriminated unions** for variant types
+- [ ] **DTO files used at boundaries** — module/API contracts are in `*.dto.ts`, not inline payload types
+
+### 5. Documentation
+
+- [ ] Complex logic has explanatory comments
+- [ ] Required docs updated per `~/.config/mosaic/guides/DOCUMENTATION.md`
+- [ ] Public APIs are documented
+- [ ] Private/internal APIs are documented
+- [ ] API input/output schemas are documented
+- [ ] API permissions/auth requirements are documented
+- [ ] Site map updates are present when navigation changed
+- [ ] README updated if needed
+- [ ] Breaking changes noted
+
+### 6. Performance
+
+- [ ] No obvious N+1 queries
+- [ ] No blocking operations in hot paths
+- [ ] Resource cleanup (connections, file handles)
+- [ ] Reasonable memory usage
+
+### 7. Dependencies
+
+- [ ] No deprecated packages
+- [ ] No unnecessary new dependencies
+- [ ] Dependency versions pinned appropriately
+
+## Review Process
+
+Use `~/.config/mosaic/templates/docs/DOCUMENTATION-CHECKLIST.md` whenever code/API/auth/infra changes are present.
+
+### Getting Context
+
+```bash
+# List the issue being addressed
+~/.config/mosaic/tools/git/issue-list.sh -i {issue-number}
+
+# View the changes
+git diff main...HEAD
+```
+
+### Providing Feedback
+
+- Be specific: point to exact lines/files
+- Explain WHY something is problematic
+- Suggest alternatives when possible
+- Distinguish between blocking issues and suggestions
+- Be constructive, not critical of the person
+
+### Feedback Categories
+
+- **Blocker**: Must fix before merge (security, bugs, test failures)
+- **Should Fix**: Important but not blocking (code quality, minor issues)
+- **Suggestion**: Optional improvements (style preferences, nice-to-haves)
+- **Question**: Seeking clarification
+
+### Review Comment Format
+
+```
+[BLOCKER] Line 42: SQL injection vulnerability
+The user input is directly interpolated into the query.
+Use parameterized queries instead:
+`db.query("SELECT * FROM users WHERE id = ?", [userId])`
+
+[SUGGESTION] Line 78: Consider extracting to helper
+This pattern appears in 3 places. A shared helper would reduce duplication.
+```
+
+## After Review
+
+1. Update issue with review status
+2. If changes requested, assign back to author
+3. If approved, note approval in issue comments
+4. For merges, ensure CI passes first
+5. Merge PR to `main` with squash strategy only

+# Documentation Standard (MANDATORY)
+
+This guide defines REQUIRED documentation behavior for all Mosaic projects.
+If code, API contracts, auth, or infrastructure changes, documentation updates are REQUIRED before completion.
+
+## Hard Rules
+
+1. Documentation is a delivery gate. Missing required documentation is a BLOCKER.
+2. `docs/PRD.md` or `docs/PRD.json` is REQUIRED as the project requirements source before coding begins.
+3. API documentation is OpenAPI-first. `docs/API/OPENAPI.yaml` (or `.json`) is the canonical API contract.
+4. Public and private/internal endpoints MUST be documented.
+5. API input and output schemas MUST be documented.
+6. API authentication and permissions MUST be documented per endpoint.
+7. A current site map MUST exist at `docs/SITEMAP.md`.
+8. Documentation updates MUST be committed in the same logical change set as the code/API change.
+9. Generated publishing output (Docusaurus/VitePress/MkDocs artifacts) is not canonical unless the project explicitly declares it canonical.
+10. `docs/` root MUST stay clean. Reports and working artifacts MUST be stored in dedicated subdirectories, not dumped at `docs/` root.
+
+## Required Documentation Structure
+
+```text
+docs/
+  PRD.md (or PRD.json)
+  TASKS.md (active orchestrator tracking, when orchestrator is used)
+  SITEMAP.md
+  USER-GUIDE/
+  ADMIN-GUIDE/
+  DEVELOPER-GUIDE/
+  API/
+    OPENAPI.yaml
+    ENDPOINTS.md
+  scratchpads/
+  reports/
+  tasks/
+  releases/
+  templates/ (optional)
+```
+
+Minimum requirements:
+
+- `docs/PRD.md` or `docs/PRD.json`: authoritative requirements source for implementation and testing.
+- `docs/USER-GUIDE/`: End-user workflows, feature behavior, common troubleshooting.
+- `docs/ADMIN-GUIDE/`: Configuration, deployment, operations, incident/recovery procedures.
+- `docs/DEVELOPER-GUIDE/`: Architecture, local setup, contribution/testing workflow, design constraints.
+- `docs/API/OPENAPI.yaml`: API SSOT for all HTTP endpoints.
+- `docs/API/ENDPOINTS.md`: Human-readable index for API endpoints, permissions, and change notes.
+- `docs/SITEMAP.md`: Navigation index for all user/admin/developer/API documentation pages.
+- `docs/reports/`: Review outputs, QA automation reports, deferrals, and audit artifacts.
+- `docs/tasks/`: Archived task snapshots and orchestrator learnings.
+- `docs/releases/`: Release notes and release-specific documentation.
+- `docs/scratchpads/`: Active task-level working notes.
+
+## Root Hygiene Rule (MANDATORY)
+
+Allowed root documentation files are intentionally limited:
+
+1. `docs/PRD.md` or `docs/PRD.json`
+2. `docs/TASKS.md` (active milestone only, when task orchestration is in use)
+3. `docs/SITEMAP.md`
+4. `docs/README.md` (optional index)
+
+All other docs MUST be placed in scoped folders (`docs/reports/`, `docs/tasks/`, `docs/releases/`, `docs/scratchpads/`, `docs/API/`, guide books).
+
+## Artifact Placement Rules
+
+| Artifact Type                              | REQUIRED Location                        |
+| ------------------------------------------ | ---------------------------------------- |
+| Code review reports, QA reports, audits    | `docs/reports/<category>/`               |
+| Deferred error lists / unresolved findings | `docs/reports/deferred/`                 |
+| Archived milestone task snapshots          | `docs/tasks/`                            |
+| Orchestrator learnings JSON                | `docs/tasks/orchestrator-learnings.json` |
+| Release notes                              | `docs/releases/`                         |
+| Active scratchpads                         | `docs/scratchpads/`                      |
+
+## API Documentation Contract (OpenAPI-First)
+
+For every API endpoint, documentation MUST include:
+
+1. visibility: `public` or `private/internal`
+2. method and path
+3. endpoint purpose
+4. request/input schema
+5. response/output schema(s)
+6. auth method and required permission/role/scope
+7. error status codes and behavior
+
+If OpenAPI cannot fully express an internal constraint, document it in `docs/API/ENDPOINTS.md`.
+
+## Book/Chapter/Page Structure
+
+Use this structure for every guide:
+
+1. Book: one root guide folder (`USER-GUIDE`, `ADMIN-GUIDE`, `DEVELOPER-GUIDE`)
+2. Chapter: one subdirectory per topic area
+3. Page: one focused markdown file per concern
+
+Required index files:
+
+1. `docs/USER-GUIDE/README.md`
+2. `docs/ADMIN-GUIDE/README.md`
+3. `docs/DEVELOPER-GUIDE/README.md`
+
+Each index file MUST link to all chapters and pages in that book.
+
+## Situational Documentation Matrix
+
+| Change Surface                                 | REQUIRED Documentation Updates                              |
+| ---------------------------------------------- | ----------------------------------------------------------- |
+| New feature or behavior change                 | User guide + developer guide + sitemap                      |
+| API endpoint added/changed/removed             | OpenAPI + API endpoint index + sitemap                      |
+| Auth/RBAC/permission change                    | API auth/permission docs + admin guide + developer guide    |
+| Database schema/migration change               | Developer guide + admin operational notes if runbook impact |
+| CI/CD or deployment change                     | Admin guide + developer guide                               |
+| Incident, recovery, or security control change | Admin guide runbook + security notes + sitemap              |
+
+## Publishing Target Rule (MANDATORY)
+
+If the user does not specify documentation publishing target, the agent MUST ask:
+
+1. Publish in-app (embedded docs)
+2. Publish on external docs platform (for example: Docusaurus, VitePress, MkDocs)
+
+Default behavior before publishing decision:
+
+- Keep canonical docs in-repo under `docs/`.
+- Do not assume external publishing platform.
+
+## Completion Gate
+
+You MUST NOT declare completion until all required documentation updates are done.
+
+Use `~/.config/mosaic/templates/docs/DOCUMENTATION-CHECKLIST.md` as the final gate.

+# E2E Delivery Procedure (MANDATORY)
+
+This guide is REQUIRED for all agent sessions.
+
+## 0. Mode Handshake (Before Any Action)
+
+First response MUST declare mode before tool calls or implementation steps:
+
+1. Orchestration mission: `Now initiating Orchestrator mode...`
+2. Implementation mission: `Now initiating Delivery mode...`
+3. Review-only mission: `Now initiating Review mode...`
+
+## 1. PRD Gate (Before Coding)
+
+1. Ensure `docs/PRD.md` or `docs/PRD.json` exists before coding.
+2. Load `~/.config/mosaic/guides/PRD.md`.
+3. Prepare/update PRD from user input and available project context.
+4. If requirements are missing:
+   - proceed with best-guess assumptions by default,
+   - mark each assumption with `ASSUMPTION:` and rationale,
+   - escalate only when uncertainty is high-impact and cannot be bounded safely.
+5. Treat PRD as the requirement source for implementation, testing, and review.
+
+## 1a. Tracking Gate (Before Coding)
+
+1. For non-trivial work, `docs/TASKS.md` MUST exist before coding.
+2. If `docs/TASKS.md` is missing, create it from `~/.config/mosaic/templates/docs/TASKS.md.template`.
+3. Detect provider first via `~/.config/mosaic/tools/git/detect-platform.sh`.
+4. For issue/PR/milestone operations, use Mosaic wrappers first (`~/.config/mosaic/tools/git/*.sh`).
+5. If external git provider is available (Gitea/GitHub/GitLab), create or update issue(s) before coding.
+6. Record provider issue reference(s) in `docs/TASKS.md` (example: `#123`).
+7. If no external provider is available, use internal task refs in `docs/TASKS.md` (example: `TASKS:T1`).
+8. Scratchpad MUST reference both task ID and issue/internal ref.
+
+## 2. Intake and Scope
+
+> **COMPLEXITY TRAP WARNING:** Intake applies to ALL tasks regardless of perceived complexity. "Simple" tasks (commit, push, deploy) have caused the most severe framework violations because agents skip intake when they pattern-match a task as mechanical. The procedure is unconditional.
+
+1. Define scope, constraints, and acceptance criteria.
+2. Identify affected surfaces (API, DB, UI, infra, auth, CI/CD, docs).
+3. **Deployment surface check (MANDATORY if task involves deploy, images, or containers):** Before ANY build or deploy action, check for CI/CD pipeline config (`.woodpecker/`, `.woodpecker.yml`, `.github/workflows/`). If pipelines exist, CI is the canonical build path — manual `docker build`/`docker push` is forbidden. Load `~/.config/mosaic/guides/CI-CD-PIPELINES.md` immediately.
+4. Identify required guides and load them before implementation.
+5. For code/API/auth/infra changes, load `~/.config/mosaic/guides/DOCUMENTATION.md`.
+6. Determine budget constraints:
+   - if the user provided a plan limit or token budget, treat it as a HARD cap,
+   - if budget is unknown, derive a working budget from estimates and runtime limits, then continue autonomously.
+7. Record budget assumptions and caps in the scratchpad before implementation starts.
+8. Track estimated vs used tokens per logical unit and adapt strategy to remain inside budget.
+9. If projected usage exceeds budget, auto-reduce scope/parallelism first; escalate only if cap still cannot be met.
+
+## 2a. Steered Autonomy (Lights-Out)
+
+1. Agent owns delivery end-to-end: planning, coding, testing, review, PR/repo operations, release/tag, and deployment (when in scope).
+2. Human intervention is escalation-only; do not pause for routine approvals or handoffs.
+3. Continue execution until completion criteria are met or an escalation trigger is hit.
+
+## 3. Scratchpad Requirement
+
+1. Create a task-specific scratchpad before implementation.
+2. Record:
+   - objective
+   - plan
+   - progress checkpoints
+   - tests run
+   - risks/blockers
+   - final verification evidence
+
+## 4. Embedded Execution Cycle (MANDATORY)
+
+For implementation work, you MUST run this cycle in order:
+
+1. `plan` - map PRD requirements to concrete implementation steps.
+2. `code` - implement one logical unit.
+3. `test` - run required baseline and situational checks for that unit.
+4. `review` - perform independent code review on the current delta.
+5. `remediate` - fix all findings and any test failures.
+6. `review` - re-review remediated changes until blockers are cleared.
+7. `commit` - commit only when the logical unit passes tests and review.
+8. `pre-push queue guard` - before pushing, wait for running/queued project pipelines to clear: `~/.config/mosaic/tools/git/ci-queue-wait.sh --purpose push`.
+9. `push` - push immediately after queue guard passes.
+10. `PR integration` - if external git provider is available, create/update PR to `main` and merge with required strategy via Mosaic wrappers.
+11. `pre-merge queue guard` - before merging PR, wait for running/queued project pipelines to clear: `~/.config/mosaic/tools/git/ci-queue-wait.sh --purpose merge`.
+12. `CI/pipeline verification` - wait for terminal CI status and require green before completion (`~/.config/mosaic/tools/git/pr-ci-wait.sh` for PR-based workflow).
+13. `issue closure` - close linked external issue (or close internal `docs/TASKS.md` task ref when provider is unavailable).
+14. `greenfield situational test` - validate required user flows in a clean environment/startup path (post-merge for trunk workflow changes).
+15. `deploy + post-deploy validation` - when deployment is in scope, deploy to configured target and run post-deploy health/smoke checks.
+16. `repeat` - continue until all acceptance criteria are complete.
+
+### Post-PR Hard Gate (Execute Sequentially, No Exceptions)
+
+1. `~/.config/mosaic/tools/git/ci-queue-wait.sh --purpose merge -B main`
+2. `~/.config/mosaic/tools/git/pr-merge.sh -n <PR_NUMBER> -m squash`
+3. `~/.config/mosaic/tools/git/pr-ci-wait.sh -n <PR_NUMBER>`
+4. `~/.config/mosaic/tools/git/issue-close.sh -i <ISSUE_NUMBER>` (or close internal `docs/TASKS.md` ref when no provider exists)
+5. If any step fails: set status `blocked`, report the exact failed wrapper command, and stop.
+6. Do not ask the human to perform routine merge/close operations.
+7. Do not claim completion before step 4 succeeds.
+
+### Forbidden Anti-Patterns
+
+**PR/Merge:**
+
+1. Do NOT stop at "PR created" or "PR updated".
+2. Do NOT ask "should I merge?" for routine delivery PRs.
+3. Do NOT ask "should I close the issue?" after merge + green CI.
+
+**Build/Deploy:** 4. Do NOT run `docker build` or `docker push` locally to deploy images when CI/CD pipelines exist in the repository. CI is the ONLY canonical build path. 5. Do NOT skip intake and surface identification because a task "seems simple." This is the #1 cause of framework violations. 6. Do NOT deploy without first verifying whether CI/CD pipelines exist (`.woodpecker/`, `.woodpecker.yml`, `.github/workflows/`). If they exist, use them. 7. If you are about to run `docker build` and have NOT loaded `ci-cd-pipelines.md`, STOP — you are violating the framework.
+
+If any step fails, you MUST remediate and re-run from the relevant step before proceeding.
+If push-queue/merge-queue/PR merge/CI/issue closure fails, status is `blocked` (not complete) and you MUST report the exact failed wrapper command.
+
+## 5. Testing Priority Model
+
+Use this order of priority:
+
+1. Situational tests are the PRIMARY gate and MUST prove changed behavior meets requirements.
+2. Baseline tests are REQUIRED safety checks and MUST run for all software changes.
+3. TDD is risk-based and REQUIRED only for specific high-risk change types.
+
+## 6. Mandatory Test Baseline
+
+For all software changes, you MUST run baseline checks applicable to the repo/toolchain:
+
+1. lint (or equivalent static checks)
+2. type checks (if language/tooling supports it)
+3. unit tests for changed logic
+4. integration tests for changed boundaries
+
+## 7. Situational Testing Matrix (PRIMARY GATE)
+
+Run additional tests based on what changed:
+
+| Change Surface               | Required Situational Tests                                                    |
+| ---------------------------- | ----------------------------------------------------------------------------- |
+| Authentication/authorization | auth failure-path tests, permission boundary tests, token/session validation  |
+| Database schema/migrations   | migration up/down validation, rollback safety, data integrity checks          |
+| API contract changes         | backward compatibility checks, consumer-impact tests, contract tests          |
+| Frontend/UI workflow changes | end-to-end flow tests, accessibility sanity checks, state transition checks   |
+| CI/CD or deployment changes  | pipeline execution validation, artifact integrity checks, rollback path check |
+| Security-sensitive logic     | abuse-case tests, input validation fuzzing/sanitization checks                |
+| Performance-critical path    | baseline comparison, regression threshold checks                              |
+
+## 8. Risk-Based TDD Requirement
+
+TDD is REQUIRED for:
+
+1. bug fixes (write a reproducer test first)
+2. security/auth/permission logic changes
+3. critical business logic and data-mutation rules
+
+TDD is RECOMMENDED (not mandatory) for low-risk UI, copy, styling, and mechanical refactors.
+If TDD is skipped for a non-required case, record the rationale in the scratchpad.
+
+## 9. Mandatory Code Review Gate
+
+If you modify source code, you MUST run an independent code review before completion.
+
+1. Use automated review tooling when available.
+2. If automated tooling is unavailable, run manual review using `~/.config/mosaic/guides/CODE-REVIEW.md`.
+3. Any blocker or critical finding MUST be fixed or tracked as an explicit remediation task before closure.
+
+## 10. Mandatory Documentation Gate
+
+For code/API/auth/infra changes, documentation updates are REQUIRED before completion.
+
+1. Apply the standard in `~/.config/mosaic/guides/DOCUMENTATION.md`.
+2. Update required docs in the same logical change set as implementation.
+3. Complete `~/.config/mosaic/templates/docs/DOCUMENTATION-CHECKLIST.md`.
+4. If publish platform is unspecified, ask the user to choose in-app or external platform before publishing.
+5. Missing required documentation is a BLOCKER.
+
+## 11. Completion Gate (All Required)
+
+You MUST satisfy all items before completion:
+
+1. Acceptance criteria met.
+2. Baseline tests passed.
+3. Situational tests passed (primary gate), including required greenfield situational validation.
+4. PRD is current and implementation is aligned with PRD.
+5. Acceptance criteria mapped to verification evidence.
+6. Code review completed for source code changes.
+7. Required documentation updates completed and reviewed.
+8. Scratchpad updated with evidence.
+9. Known risks documented.
+10. No unresolved blocker hidden.
+11. If deployment is in scope, deployment target, release version, and post-deploy verification evidence are documented.
+12. `docs/TASKS.md` status and issue/internal references are updated to match delivered work.
+13. If source code changed and external provider is available: PR merged to `main` (squash), with merge evidence recorded.
+14. CI/pipeline status is terminal green for the merged PR/head commit.
+15. Linked external issue is closed (or internal task ref is closed when no provider exists).
+16. If any of items 13-15 fail due access/tooling, report `blocked` with exact failed wrapper command and do not claim completion.
+
+## 12. Review and Reporting
+
+Completion report MUST include:
+
+1. what changed
+2. PRD alignment summary
+3. acceptance criteria to evidence mapping
+4. what was tested (baseline + situational)
+5. what was reviewed (code review scope)
+6. what documentation was updated
+7. command-level evidence summary
+8. residual risks
+9. deployment and post-deploy verification summary (if in scope)
+10. explicit pass/fail status
+11. tracking summary (`docs/TASKS.md` updates and issue/internal refs)
+12. PR lifecycle summary (PR number, merge commit, merge method)
+13. CI/pipeline summary (run/check URL, terminal status)
+14. issue closure summary (issue number/ref and close evidence)

+# Frontend Development Guide
+
+## Before Starting
+
+1. Check assigned issue in git repo: `~/.config/mosaic/tools/git/issue-list.sh -a @me`
+2. Create scratchpad: `docs/scratchpads/{issue-number}-{short-name}.md`
+3. Review existing components and patterns in the codebase
+
+## Development Standards
+
+### Framework Conventions
+
+- Follow project's existing framework patterns (React, Vue, Svelte, etc.)
+- Use existing component library/design system if present
+- Maintain consistent file structure with existing code
+
+### Styling
+
+- Use project's established styling approach (CSS modules, Tailwind, styled-components, etc.)
+- Follow existing naming conventions for CSS classes
+- Ensure responsive design unless explicitly single-platform
+
+### State Management
+
+- Use project's existing state management solution
+- Keep component state local when possible
+- Document any new global state additions
+
+### Accessibility
+
+- Include proper ARIA labels
+- Ensure keyboard navigation works
+- Test with screen reader considerations
+- Maintain color contrast ratios (WCAG 2.1 AA minimum)
+
+## Testing Requirements (TDD)
+
+1. Write tests BEFORE implementation
+2. Minimum 85% coverage
+3. Test categories:
+   - Unit tests for utility functions
+   - Component tests for UI behavior
+   - Integration tests for user flows
+
+### Test Patterns
+
+```javascript
+// Component test example structure
+describe('ComponentName', () => {
+  it('renders without crashing', () => {});
+  it('handles user interaction correctly', () => {});
+  it('displays error states appropriately', () => {});
+  it('is accessible', () => {});
+});
+```
+
+## Code Style
+
+- Follow Google JavaScript/TypeScript Style Guide
+- **TypeScript: Follow `~/.config/mosaic/guides/TYPESCRIPT.md` — MANDATORY**
+- Use ESLint/Prettier configuration from project
+- Prefer functional components over class components (React)
+- TypeScript strict mode is REQUIRED, not optional
+
+### TypeScript Quick Rules (see TYPESCRIPT.md for full guide)

+# Infrastructure & DevOps Guide
+
+## Before Starting
+
+1. Check assigned issue: `~/.config/mosaic/tools/git/issue-list.sh -a @me`
+2. Create scratchpad: `docs/scratchpads/{issue-number}-{short-name}.md`
+3. Review existing infrastructure configuration
+
+## Vault Secrets Management
+
+**CRITICAL**: Follow canonical Vault structure for ALL secrets.
+
+### Structure
+
+```
+{mount}/{service}/{component}/{secret-name}
+
+Examples:
+- secret-prod/postgres/database/app
+- secret-prod/redis/auth/default
+- secret-prod/authentik/admin/token
+```
+
+### Environment Mounts
+
+- `secret-dev/` - Development environment
+- `secret-staging/` - Staging environment
+- `secret-prod/` - Production environment
+
+### Standard Field Names
+
+- Credentials: `username`, `password`
+- Tokens: `token`
+- OAuth: `client_id`, `client_secret`
+- Connection strings: `url`, `host`, `port`
+
+See `docs/vault-secrets-structure.md` for complete reference.
+
+## Container Standards
+
+### Dockerfile Best Practices
+
+```dockerfile
+# Use specific version tags
+FROM node:20-alpine
+
+# Create non-root user
+RUN addgroup -S app && adduser -S app -G app
+
+# Set working directory
+WORKDIR /app
+
+# Copy dependency files first (layer caching)
+COPY package*.json ./
+RUN npm ci --only=production
+
+# Copy application code
+COPY --chown=app:app . .
+
+# Switch to non-root user
+USER app
+
+# Use exec form for CMD
+CMD ["node", "server.js"]
+```
+
+### Container Security
+
+- Use minimal base images (alpine, distroless)
+- Run as non-root user
+- Don't store secrets in images
+- Scan images for vulnerabilities
+- Pin dependency versions
+
+## Kubernetes/Docker Compose
+
+### Resource Limits
+
+Always set resource limits to prevent runaway containers:
+
+```yaml
+resources:
+  requests:
+    memory: '128Mi'
+    cpu: '100m'
+  limits:
+    memory: '256Mi'
+    cpu: '500m'
+```
+
+### Health Checks
+
+```yaml
+livenessProbe:
+  httpGet:
+    path: /health
+    port: 8080
+  initialDelaySeconds: 10
+  periodSeconds: 5
+
+readinessProbe:
+  httpGet:
+    path: /ready
+    port: 8080
+  initialDelaySeconds: 5
+  periodSeconds: 3
+```
+
+## CI/CD Pipelines
+
+### Pipeline Stages
+
+1. **Lint**: Code style and static analysis
+2. **Test**: Unit and integration tests
+3. **Build**: Compile and package
+4. **Scan**: Security and vulnerability scanning
+5. **Deploy**: Environment-specific deployment
+
+### Pipeline Security
+
+- Use secrets management (not hardcoded)
+- Pin action/image versions
+- Implement approval gates for production
+- Audit pipeline access
+
+## Steered-Autonomous Deployment (Hard Rule)
+
+In lights-out mode, the agent owns deployment end-to-end when deployment is in scope.
+The human is escalation-only for missing access, hard policy conflicts, or irreversible risk.
+
+### Deployment Target Selection
+
+1. Use explicit target from `docs/PRD.md` / `docs/PRD.json` or `docs/DEPLOYMENT.md`.
+2. If unspecified, infer from existing project config/integration.
+3. If multiple targets exist, choose the target already wired in CI/CD and document rationale.
+
+### Supported Targets
+
+- **Portainer**: Deploy via `~/.config/mosaic/tools/portainer/stack-redeploy.sh`, then verify with `stack-status.sh`.
+- **Coolify**: Deploy via `~/.config/mosaic/tools/coolify/deploy.sh -u <uuid>`, then verify with `service-status.sh`.
+- **Vercel**: Deploy via `vercel` CLI or connected Git integration, then verify preview/production URL health.
+- **Other SaaS providers**: Use provider CLI/API/runbook with the same validation and rollback gates.
+
+### Coolify API Operations
+
+```bash
+# List projects and services
+~/.config/mosaic/tools/coolify/project-list.sh
+~/.config/mosaic/tools/coolify/service-list.sh
+
+# Check service status
+~/.config/mosaic/tools/coolify/service-status.sh -u <uuid>
+
+# Set env vars (takes effect on next deploy)
+~/.config/mosaic/tools/coolify/env-set.sh -u <uuid> -k KEY -v VALUE
+
+# Deploy
+~/.config/mosaic/tools/coolify/deploy.sh -u <uuid>
+```
+
+**Known Coolify Limitations:**
+
+- FQDN updates on compose sub-apps not supported via API (DB workaround required)
+- Compose files must be base64-encoded in `docker_compose_raw` field
+- Magic variables (`SERVICE_FQDN_*`) require list-style env syntax, not dict-style
+- Rate limit: 200 requests per interval
+
+### Cloudflare DNS Operations
+
+Use the Cloudflare tools for any DNS configuration: pointing domains at services, adding TXT verification records, managing MX records, etc.
+
+**Multi-instance support**: Credentials support named instances (e.g. `personal`, `work`). A `default` key in credentials.json determines which instance is used when `-a` is omitted. Pass `-a <instance>` to target a specific account.
+
+```bash
+# List all zones (domains) in the account
+~/.config/mosaic/tools/cloudflare/zone-list.sh [-a instance]
+
+# List DNS records for a zone (accepts zone name or ID)
+~/.config/mosaic/tools/cloudflare/record-list.sh -z <zone> [-t type] [-n name]
+
+# Create a DNS record
+~/.config/mosaic/tools/cloudflare/record-create.sh -z <zone> -t <type> -n <name> -c <content> [-p] [-l ttl] [-P priority]
+
+# Update a DNS record (requires record ID from record-list)
+~/.config/mosaic/tools/cloudflare/record-update.sh -z <zone> -r <record-id> -t <type> -n <name> -c <content> [-p]
+
+# Delete a DNS record
+~/.config/mosaic/tools/cloudflare/record-delete.sh -z <zone> -r <record-id>
+```
+
+**Flag reference:**
+
+| Flag | Purpose                                                                 |
+| ---- | ----------------------------------------------------------------------- |
+| `-z` | Zone name (e.g. `mosaicstack.dev`) or 32-char zone ID                   |
+| `-a` | Named Cloudflare instance (omit for default)                            |
+| `-t` | Record type: `A`, `AAAA`, `CNAME`, `MX`, `TXT`, `SRV`, etc.             |
+| `-n` | Record name: short (`app`) or FQDN (`app.example.com`)                  |
+| `-c` | Record content/value (IP, hostname, TXT string, etc.)                   |
+| `-r` | Record ID (from `record-list.sh` output)                                |
+| `-p` | Enable Cloudflare proxy (orange cloud) — omit for DNS-only (grey cloud) |
+| `-l` | TTL in seconds (default: `1` = auto)                                    |
+| `-P` | Priority for MX/SRV records                                             |
+| `-f` | Output format: `table` (default) or `json`                              |
+
+**Common workflows:**
+
+```bash
+# Point a new subdomain at a server (proxied through Cloudflare)
+~/.config/mosaic/tools/cloudflare/record-create.sh \
+  -z example.com -t A -n myapp -c 203.0.113.10 -p
+
+# Add a TXT record for domain verification (never proxied)
+~/.config/mosaic/tools/cloudflare/record-create.sh \
+  -z example.com -t TXT -n _verify -c "verification=abc123"
+
+# Check what records exist before making changes
+~/.config/mosaic/tools/cloudflare/record-list.sh -z example.com -t CNAME
+
+# Update an existing record (get record ID from record-list first)
+~/.config/mosaic/tools/cloudflare/record-update.sh \
+  -z example.com -r <record-id> -t A -n myapp -c 10.0.0.5 -p
+```
+
+**DNS + Deployment integration**: When deploying a new service via Coolify or Portainer that needs a public domain, the typical sequence is:
+
+1. Create the DNS record pointing at the host IP (with `-p` for Cloudflare proxy if desired)
+2. Deploy the service via Coolify/Portainer
+3. Verify the domain resolves and the service is reachable
+
+**Proxy (`-p`) guidance:**
+
+- Use proxy (orange cloud) for web services — provides CDN, DDoS protection, and hides origin IP
+- Skip proxy (grey cloud) for non-HTTP services (mail, SSH), wildcard records, or when the service handles its own TLS termination and needs direct client IP visibility
+- Proxy is NOT compatible with non-standard ports outside Cloudflare's supported range
+
+### Stack Health Check
+
+Verify all infrastructure services are reachable:
+
+```bash
+~/.config/mosaic/tools/health/stack-health.sh
+```
+
+### Image Tagging and Promotion (Hard Rule)
+
+For containerized deployments:
+
+1. Build immutable image tags: `sha-<shortsha>` and `v{base-version}-rc.{build}`.
+2. Use mutable environment tags only as pointers: `testing`, optional `staging`, and `prod`.
+3. Deploy by immutable digest, not by mutable tag alone.
+4. Promote the exact tested digest between environments (no rebuild between testing and prod).
+5. Do not use `latest` or `dev` as deployment references.
+
+Blue-green is the default strategy for production promotion.
+Canary is allowed only when automated SLO/error-rate gates and auto-rollback triggers are implemented.
+
+### Post-Deploy Validation (REQUIRED)
+
+1. Health endpoints return expected status.
+2. Critical smoke tests pass in target environment.
+3. Running version and digest match the promoted release candidate.
+4. Observability signals (errors/latency) are within expected thresholds.
+
+### Rollback Rule
+
+If post-deploy validation fails:
+
+1. Execute rollback/redeploy-safe path immediately.
+2. Mark deployment as blocked in `docs/TASKS.md`.
+3. Record failure evidence and next remediation step in scratchpad and release notes.
+
+### Registry Retention and Cleanup
+
+Cleanup MUST be automated.
+
+- Keep all final release tags (`vX.Y.Z`) indefinitely.
+- Keep active environment digests (`prod`, `testing`, and active blue/green slots).
+- Keep recent RC tags (`vX.Y.Z-rc.N`) based on retention window.
+- Remove stale `sha-*` and RC tags outside retention window if they are not actively deployed.
+
+## Monitoring & Logging
+
+### Logging Standards
+
+- Use structured logging (JSON)
+- Include correlation IDs
+- Log at appropriate levels (ERROR, WARN, INFO, DEBUG)
+- Never log sensitive data
+
+### Metrics to Collect
+
+- Request latency (p50, p95, p99)
+- Error rates
+- Resource utilization (CPU, memory)
+- Business metrics
+
+### Alerting
+
+- Define SLOs (Service Level Objectives)
+- Alert on symptoms, not causes
+- Include runbook links in alerts
+- Avoid alert fatigue
+
+## Testing Infrastructure
+
+### Test Categories
+
+1. **Unit tests**: Terraform/Ansible logic
+2. **Integration tests**: Deployed resources work together
+3. **Smoke tests**: Critical paths after deployment
+4. **Chaos tests**: Failure mode validation
+
+### Infrastructure Testing Tools
+
+- Terraform: `terraform validate`, `terraform plan`
+- Ansible: `ansible-lint`, molecule
+- Kubernetes: `kubectl dry-run`, kubeval
+- General: Terratest, ServerSpec

+# Memory and Retention Rules
+
+## Primary Memory Layer: OpenBrain
+
+**OpenBrain is the canonical shared memory for all Mosaic agents across all harnesses and sessions.**
+
+Use the `capture` MCP tool (or REST `POST /v1/thoughts`) to store:
+
+- Discovered gotchas and workarounds
+- Architectural decisions and rationale
+- Project state and context for handoffs
+- Anything a future agent should know
+
+Use `search` or `recent` at session start to load prior context before acting.
+
+This is not optional. An agent that uses local file-based memory instead of OpenBrain is a broken agent — its knowledge is invisible to every other agent on the platform.
+
+## Hard Rules
+
+1. Agent learnings MUST go to OpenBrain — not to any file-based memory location.
+2. You MUST NOT write to runtime-native memory silos (they are write-blocked by hook).
+3. Active execution state belongs in project `docs/` — not in memory files.
+4. `~/.config/mosaic/memory/` is for mosaic framework technical notes only, not project knowledge.
+
+## Runtime-Native Memory Silos (WRITE-BLOCKED)
+
+These locations are blocked by PreToolUse hooks. Attempting to write there fails at the tool level.
+
+| Runtime     | Blocked silo                       | Use instead         |
+| ----------- | ---------------------------------- | ------------------- |
+| Claude Code | `~/.claude/projects/*/memory/*.md` | OpenBrain `capture` |
+| Codex       | Runtime session memory             | OpenBrain `capture` |
+| OpenCode    | Runtime session memory             | OpenBrain `capture` |
+
+MEMORY.md files may only contain behavioral guardrails that must be injected at load-path — not knowledge.
+
+## Project Continuity Files (MANDATORY)
+
+| File                             | Purpose                                   | Location                    |
+| -------------------------------- | ----------------------------------------- | --------------------------- |
+| `docs/PRD.md` or `docs/PRD.json` | Source of requirements                    | Project `docs/`             |
+| `docs/TASKS.md`                  | Task tracking, milestones, issues, status | Project `docs/`             |
+| `docs/scratchpads/<task>.md`     | Task-specific working memory              | Project `docs/scratchpads/` |
+| `AGENTS.md`                      | Project-local patterns and conventions    | Project root                |
+
+## How the Block Works
+
+`~/.config/mosaic/tools/qa/prevent-memory-write.sh` is registered as a `PreToolUse` hook in
+`~/.claude/settings.json`. It intercepts Write/Edit/MultiEdit calls and rejects any targeting
+`~/.claude/projects/*/memory/*.md` before the tool executes. Exit code 2 blocks the call and
+the agent sees a message directing it to OpenBrain instead.
