GodopuandClaude Opus 5.5 47fe24e07c feat: multi-agent-mux-update skill and in-place install (Issue #72)
The update is a skill (decision 4); deploy/update.sh and the installed
.mam_deploy/update.sh are gone.

- Phase 1 (installed code, update.sh): publish the update marker under the
  exclusive admission lock; refuse before any change while a running row, a
  live herdr agent in the workspace on any running server, an open job
  (unreadable JSON included, dry_run not), a live loop marker or a
  monitor.lock held by a monitor the skills did not start (U3) is there - the
  calling agent (server + pane, its row and one running job) excepted
  (lib_py/update.py precheck, decisions 1 and 7). Stop the monitor (TERM, then
  KILL and restart it if it does not end; decision 2), handle a leftover
  backup by its state (U4), back up .agents, .mam_deploy, root files, .venv,
  the installer's .mam files and the registry (SQLite backup API under the
  registry lock) into .mam/update-backup/, then exec a copy of
  install_phase.sh outside the tree (decision 5).
- The copy (no lib.sh/lib_py, bash 3.2) runs the installer in place; on
  failure it restores the backup and restarts the monitor from the restored
  tree; on success it runs phase 2, post_update.sh of the new tree, which
  converts the registry with lib_py.registry_format and restarts the monitor
  if it ran. The backup and the marker are removed at the end.
- install.sh updates in place (decisions 3, 4, 9): install_state keys are set,
  one line each; no updater is installed and an old one (.mam_deploy/update.sh,
  or a root update.sh the manifest lists) is removed; framework files the new
  version no longer ships are deleted when unmodified, kept and listed when
  modified, and dropped from base/, the manifest and asset_hashes.txt; a local
  source's .mam is not staged. remove.sh knows the new skill; CI shellchecks
  its scripts; docs point at the skill.
- test_issue8_update_state and test_deploy_layout td6/td27 run the skill.

description: "Update an installed MAM workspace in place to the latest version. Refuses while a session, an open job, a review loop or an unknown monitor is live; stops the monitor daemon and starts it again afterwards; rolls everything back if the install fails; converts the registry with the newly installed code. Use instead of the removed .mam_deploy/update.sh."

# Multi-Agent Update
```bash
bash .agents/skills/multi-agent-mux-update/scripts/update.sh --yes
```
| Item | Behaviour |
|---|---|
| Where | An installed workspace only (`.mam_deploy/remove.sh` present). A git checkout updates with `git pull`. |
| Confirmation | `[y/N]` prompt; without a terminal `-y`/`--yes` is required. There is no force option. |
| Refused when | a running registry row, a live herdr agent whose cwd is in the workspace (any running server), an open job (unreadable job JSON included, `dry_run` excluded), a live loop marker, `.mam/monitor.lock` held by a monitor the skills did not start, or another update. The calling agent (its herdr server + pane, row and one running job) is not counted. Each refusal lists the cleanup; nothing is changed. |
| During the update | create, resume, `run_loop.sh`, delegate submit, stop and orc-onboard refuse (`.mam/update-in-progress`, `.mam/update-admission.lock`). |
| Monitor | stopped first, started again afterwards only if it ran (`MAM_NO_SUBSCRIBER_DAEMON=1`: not started). |
| Install | the installer at `MAM_INSTALLER_URL` (default: Gitea `main`) runs in place; `.mam` is kept. On failure `.agents/`, `.mam_deploy/`, root files, `.venv`, the installer's `.mam` files and the registry are restored from `.mam/update-backup/`. |
| Registry | converted by the new code (`lib_py.registry_format`); a failed conversion keeps the install and exits nonzero. |
| Exit | `0` updated, `1` refused or failed, `2` bad arguments. |
