The fold checkpoint (_system/fold-checkpoint.json) is stamped strictly after a canonical-sync barrier over every live entity touched since the last stamp (syncEntityCanonical: ids → canonical paths → fsync; an absent file fsyncs its parent directory so deletes are as durable as writes). An unclean open under log authority now folds only (checkpoint, head]; the chain bootstraps at an empty brain's adoption (three-phase hooks around adoptLogAuthority) or at a brain's first whole-log fold — existing brains converge at their first crash with zero regression. Rollback restores sync immediately; abort paths feed the barrier; a failed barrier retains the old bound (bigger fold later, never a lost write). Five structural pins including boundedness itself. Also: the production-shaped write-flow gate leg (mixed traffic racing flushes, crash mid-traffic, every ack survives — from a consumer-reported gate miss), and two release-ceremony cures (tag-first push so the publish never queues behind the release commit's CI run; raw-curl npmjs shasum probe with propagation grace instead of a one-shot false divergence). |
