The weekly upgrade run now executes inside a dedicated, remote-control agent
(cc-ci-upgrader) — viewable/steerable at claude.ai/code like the Builder — rather
than buried in headless cron output.
- launch-upgrader.sh: spins up the cc-ci-upgrader tmux session under
--remote-control with a kickoff that runs /upgrade-all (DEFAULT mode) to
completion. On finish the agent STOPS and stays idle (does NOT self-terminate)
so the run + summary stay reviewable in the web UI. `start` = use-or-create:
leaves an in-flight (busy) run alone, else clears a finished/idle/wedged
session and runs fresh; `fresh` always restarts. UPGRADER_ARGS passes flags
(e.g. --dry-run); never --with-tests.
- launch.sh: orchestrator_alive() now also skips the cc-ci-upgrader
remote-control name, so the upgrader job isn't mistaken for the orchestrator.
- upgrade-all skill: documents it runs as the cc-ci-upgrader agent; the weekly
cron invokes `launch-upgrader.sh start` (not /upgrade-all inline).
- Phase 5: V8a verifies the agent lifecycle (launch → run to completion → stay
idle/viewable → next start clears it); V9 stops the verification session.
- cron memory: weekly task = launch-upgrader.sh start at 0 3 * * 6 UTC.
