Coordination ledger for coding agents: what was decided, what's still open, where you parked — durable across sessions, repos, and weeks. Memory tools store what the agent knows; Director tracks the state of the work. Run both: they don't overlap. Claude Code + Codex + OpenCode.
Long-running coding sessions for the Milpa PHP framework: an event-sourced session that survives the process, so an agent can be paused, resumed, audited and stopped.
