Failure Modes

BD_NOT_FOUND

• Cause: bd missing from PATH.
• Recovery: install beads CLI or add bd executable directory to PATH.

BB_NOT_FOUND

• Cause: BB_REPO invalid or no bb command / cache / discovery hit.
• Recovery:
  • Set BB_REPO to BeadBoard repo root.
  • Verify bb.ps1 exists under BB_REPO.
  • Retry preflight.

NAME_GENERATION_EXHAUSTED

• Cause: all generated names collided with existing registry entries.
• Recovery:
  • increase retry count (BB_NAME_MAX_RETRIES),
  • expand adjective/noun pools,
  • retry generation.

Reservation Conflicts

• RESERVATION_CONFLICT: active owner exists.
• RESERVATION_STALE_FOUND: stale reservation exists; use takeover only when safe.
• RELEASE_FORBIDDEN: non-owner attempted release.

Mail Lifecycle Errors

• UNKNOWN_SENDER / UNKNOWN_RECIPIENT: register agents before send.
• ACK_FORBIDDEN: only recipient may ack.
• MESSAGE_NOT_FOUND: stale id or wrong message reference.

Policy Guardrails

• Do not write .beads/issues.jsonl directly.
• Do not close beads without verification evidence.
• Do not bypass BB_REPO when it is set but invalid; fix it explicitly.
