Git Notes Agent Memory
Two modes
1) Canonical handoff (default) — Single cumulative note on refs/notes/agent-memory at HEAD. Session start: ./agent-memory.sh read. After every commit: write or write-message. One next; append-only decisions. Last writer wins if two agents share only this ref.
2) Parallel agents + overlap detection — Each agent writes its own note with ./agent-memory.sh write-agent <id> (stdin) or write-agent-message <id> <text>. Notes live under refs/notes/am-agents/<id> (a sibling of the canonical ref; you cannot nest .../agent-memory/agents/... in Git because refs/notes/agent-memory is already a ref). Put task_id and hypothesis_hash on their own lines in YAML (see SCHEMA.md, Optional — Phase 3). Coordinator runs ./agent-memory.sh aggregate on HEAD to print wasteful_duplicate vs healthy_parallel heuristics. Use read-agent <id>, list-agents.
Common: ./agent-memory.sh init once. No raw git notes without the correct --ref. Commit before write on the ref you intend. Push notes explicitly: git push origin refs/notes/agent-memory and git push origin 'refs/notes/am-agents/*' (see init output).
Full fields, examples, and aggregation rules: SCHEMA.md. Reproducible scenarios: agent-memory-lab repo (EXPERIMENT_PHASE2.md, EXPERIMENT_PHASE3.md).
