Two independent reviews converged on the same root cause: nothing bounded how long primary metadata could stay wrong once the shallow watcher stopped reporting. Four distinct paths led there. - A terminal watch error arriving while the status-ref poll was still starting left the repo with status-ref coverage only. handleWatcherError ran its teardown against nulls, then the in-flight poll installed itself, and the fallback guard mistook it for coverage and discarded the fallback. Primary metadata was then never observed again. The guard no longer treats status-ref polling as primary coverage, and startup re-checks watcher liveness after its awaits. - Nothing re-read the six primary files while the watcher was nominally live. A lossy notification path, a dropped batch, or inotify queue overflow raises no error, so the error-driven fallback never fired and the inode rebind sweep does not detect loss. A 15-tick backstop re-stats them, turning permanent staleness into one tick. Measured cost is ~0.2 stats/s/repo against the 3/s the old poll cost. - Reconciliation treated any late-observed entry create as a root replacement, so an ordinary tore down a healthy stream ~30s later and opened a deaf window. It now also requires the root itself to be recreated. - The shallow watcher recorded directory identity from a stat issued after binding, so a replacement in that gap pinned the dead inode's watcher to the new identity and the sweep would never rebind. Identity is now read first, which errs toward a harmless extra rebind. Test helper: replacing the worktrees root frees several inodes at once, so reserving one still let the recreated root reuse its own. It now verifies the inode actually changed. Confirmed on ext4, where three holds were needed.
