headless

A coding agent loses its context every session, so a project that runs for days needs its memory in the repository. Make the coordinator a small script and a JSON ledger, run every worker as a fresh `claude -p` session in its own git worktree with a hard scope and budget, and have the coordinator verify and merge the work itself. Tested with a stub worker; flags pinned to Claude Code 2.1.310.

A claude -p run on Opus with an API key gives up after three consecutive 529s, about 1.5 seconds of backoff, no matter what CLAUDE_CODE_MAX_RETRIES says. Add --fallback-model, set CLAUDE_CODE_RETRY_WATCHDOG=1 with a max wait, or widen the 529 backoff with the OVERLOADED_RETRY delay variables. Checked against Claude Code 2.1.309.
