Operator decision at review: 15 min is aggressive for config churn; hourly
keeps the stale-window acceptable (<=1 h) with a fifth of the wakeups.
Timer unit, tier law, and failure-table wording aligned.
The checkout IS the deployment and symlinks make live state (memories,
auto-learned skills, agent config, desktop settings) dirty tracked files
continuously; no commit law covered machine churn, so it accumulated
unpushed for weeks — one disk held the only copy of ~61 managed skills,
a settings fix stayed local-only, and dirty trees refused merges.
scripts/live-sync.sh (systemd user timer, ~15 min) commits ONLY the
allowlisted machine/desktop-live tiers with hooks armed, merges
origin/main, pushes, and reaps wt/* worktrees older than 7 days. Task
dirt outside the allowlist is never staged; conflicts abort and alert
via ntfy; branch guard refuses off main; never --no-verify, never force.
Black-box contract pinned by tests/live-sync.bats (9 tests, suite 36/36).
