* fix(replication): tolerate orphaned resync intents at startup Since #5215 (1.0.0-beta.12) startup reconciles every pending/started resync intent in resync.bin against the bucket's configured targets and aborts the whole server when an intent has no matching target ARN. A resync whose remote target was later removed leaves exactly such an orphan on disk, so every later start fails with "accepted replication resync target ... is not configured" regardless of the binary version. Skip orphaned intents with a warning instead of failing startup; the resync routine already settles them to ResyncFailed. Cancel the intent when its remote target is removed so the orphan is not created again. Fixes #4784 * fix(replication): cancel removed-target resync under the admission lock Canceling through this node's cached whole-bucket status map could persist a map that predates another node's admission, erasing that node's durable restart intent. Reload resync.bin under the bucket admission lock, publish the fresh map, and only then mark the removed target's intent canceled. Two-node regression covers the clobber. * fix(replication): persist resync status via ETag CAS merge mark_status, the periodic saver, admission, and removed-target cancellation all persisted their node's cached whole-bucket map, so any one node's stale cache could resurrect states another node had already finalized (a canceled intent flipping back to Pending, an admission vanishing). All resync.bin writers now go through update_resync_status_cas: load the freshest document with its ETag, apply a per-target mutation with staleness and canceled-is-terminal guards re-checked against the persisted entry, and save conditionally, retrying on concurrent writes. The periodic saver merges per target, letting terminal states and newer admissions recorded elsewhere win. Cache convergence stays per-target so locally running resyncs keep their authoritative progress counters. Regressions: stale_peer_status_write_cannot_resurrect_canceled_intent (node B's pre-cancel cache marking its own run Started must not revive node A's canceled intent) plus unit coverage for the periodic-save merge. * test(ecstore): rename resync test helper off the guarded contract name fn resync_target is on the architecture guard's reserved list for crates/replication operation contracts; the merge-test helper now reads resync_target_state. * fix(replication): serialize resync status updates --------- Co-authored-by: overtrue <anzhengchao@gmail.com>
