Work packages completed: - WP1: packages/forge — pipeline runner, stage adapter, board tasks, brief classifier, persona loader with project-level overrides. 89 tests, 95.62% coverage. - WP2: packages/macp — credential resolver, gate runner, event emitter, protocol types. 65 tests, 96.24% coverage. Full Python-to-TS port preserving all behavior. - WP3: plugins/mosaic-framework — OC rails injection plugin (before_agent_start + subagent_spawning hooks for Mosaic contract enforcement). - WP4: profiles/ (domains, tech-stacks, workflows), guides/ (17 docs), skills/ (5 universal skills), forge pipeline assets (48 markdown files). Board deliberation: docs/reviews/consolidation-board-memo.md Brief: briefs/monorepo-consolidation.md Consolidates mosaic/stack (forge, MACP, bootstrap framework) into mosaic/mosaic-stack. 154 new tests total. Zero Python — all TypeScript/ESM.

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
- Agent learnings MUST go to OpenBrain — not to any file-based memory location.
- You MUST NOT write to runtime-native memory silos (they are write-blocked by hook).
- Active execution state belongs in project
docs/— not in memory files. ~/.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.
