Two defects with one root, found by the fold-checkpoint work's first integration gate. (1) THE RACE: restore() never quiesced the generation store, so a background flush could write into _system/ while the swap was removing it — observed as ENOTEMPTY mid-swap when a checkpoint stamp landed between readdir and rmdir. The swap now runs inside the store's exclusive section (runStateReplacement): flush timer disarmed, pending tier and checkpoint accumulator discarded BEFORE any directory moves. (2) THE INHERITED ASSERTION: a snapshot carries its source brain's clean-shutdown marker and fold checkpoint, but the restored files were bulk-copied without per-file fsync — the inherited stamps would suppress exactly the recovery fold that cures a post-restore power cut. reopenAfterRestore now deletes both stamps before reopening: the open treats the store as uncleanly shut, folds the restored log into canonical, barrier-syncs what it re-applied, and stamps fresh — the restored state is durably founded at restore time instead of borrowing assertions about bytes this disk never synced. Pinned: restore under in-flight traffic completes; the pre-restore stamp does not survive; the post-restore stamp is the reopen fold's own, at the restored watermark. |
