A message starting with `?` in a mapped room runs `claude -p` one-shot in that
repo on the Mac and posts the full answer back into the room — Matrix as a
request/response interface, not just a trigger. Non-`?` messages keep launching
interactive sessions as before.
New scripts/ask-claude.sh is a login-shell wrapper (so ~/.zprofile puts claude on
PATH) that exports CLAUDE_CODE_OAUTH_TOKEN from the Mac's .env and runs
`claude -p "$prompt" < /dev/null`, printing the answer to stdout. The bot adds a
`?`-dispatch with run_ask/ask: SSH stdout captured, 300s timeout, fail-loud, output
chunked under Matrix's event cap (no truncation).
Headless claude -p needs the long-lived token because a non-GUI SSH session can't
reach the login Keychain (reports "Not logged in") — the deliberate Approach A that
the interactive GUI-Terminal path (D11) avoided. Token is kept Mac-side only; the
Spark never runs claude. Sovereignty unchanged: claude -p uses the subscription, no
frontier API touches message payloads.
Proven live on the Spark; fresh-eyes reviewed before commit.
Phase 0 proven by hand (N=3) across multiple rooms.
- scripts/gui-launch.sh: open a desktop Terminal via osascript so claude runs in
the GUI session (login Keychain + real TTY), avoiding a long-lived token (D11).
- scripts/launch-claude.sh: name the session `claude -n "<repo> - <topic>"` so
Remote Control's phone conversation index is readable.
- .env.example: bot credential schema (real .env stays gitignored).
- AGENTS.md / ROADMAP.md: D11, Phase 0 results, Phase 1 carry-overs.
