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.
