* feat(s3/lifecycle): pointer-transition routing for live PUTs (Phase 5b/4) Bootstrap covers existing versions, but a live PUT that creates a new .versions/<v-new> file and updates the parent's ExtLatestVersionIdKey didn't fire NoncurrentDays / NewerNoncurrent on the displaced prior version until the next bootstrap. Close that runtime gap. The meta-log already emits an Update event for the .versions/ directory itself when the latest pointer changes; the router was dropping it because buildObjectInfo returns nil for directories. New branch in Route detects that shape (versioned bucket, NewEntry + OldEntry both directories with the .versions/ suffix, ExtLatestVersionIdKey changed, ID different from the new ID) and emits a Match against the LOGICAL key with VersionID=oldID. Match.Identity comes from a single LookupVersion RPC for the displaced version file; SuccessorModTime is the directory update's mtime, which is the moment the displaced version became noncurrent. SiblingLister grows LookupVersion(bucket, key, versionID) for that single-RPC fetch. filerSiblingLister implements it; routing path treats NotFound as "displaced version was hard-deleted in the meantime, suppress" rather than an error. The router gates the lookup on at least one active event-driven NoncurrentDays / NewerNoncurrent rule for the bucket, so most buckets pay nothing per directory update. Tests: pointer-flip fires NoncurrentDays with displaced version_id; unchanged pointer skips; empty old pointer skips (first-PUT scenario); displaced-version NotFound suppresses; no-rule skips lookup; NewerNoncurrentVersions retains rank-0; unversioned bucket skips. * fix(s3/lifecycle): SuccessorModTime cache + NewerNoncurrent expansion Two correctness gaps in pointer-transition routing. The .versions/ directory's own Attributes.Mtime is preserved across pointer updates by updateLatestVersionInDirectory: it's a stale clock relative to the freshly-written latest version. Using it as the displaced version's SuccessorModTime made NoncurrentDays compute due = staleMtime + days, which fires immediately on a fresh PUT into an old .versions/ container. Read ExtLatestVersionMtimeKey written by setCachedListMetadata; suppress (return no matches) when the cache is missing rather than fall back to dir mtime. Single-oldID lookup is only enough for pure NoncurrentVersionExpirationDays. Any rule with NewerNoncurrentVersions > 0 cares about the noncurrent ranks, and a pointer flip shifts every prior noncurrent's index by one — the version that just crossed the keep-count threshold needs to be evaluated too. When any matching rule needs ranks, list the full .versions/ container, sort newest- first with mtime + version-id tiebreak, and route every noncurrent with its real index. Identity-CAS dedups against earlier schedules. SiblingLister grows ListVersions(bucket, key); filerSiblingLister's implementation paginates the container fully. Two regression tests: stale dir mtime + correct cached mtime schedules ~30 days out (not immediate); NewerNoncurrentVersions=2 with 4 versions fires on the rank-2 entry that just crossed the threshold while rank-0/1 are retained. * fix(s3/lifecycle): bound pointer-transition expansion to threshold crossings routePointerTransitionExpand emitted a Match for every eligible noncurrent on every PUT. Schedule.Add doesn't dedup, so identity-CAS at dispatch only saved the wasted RPC, not the heap slot. A hot key with many already-eligible versions and a count rule would push O(versions) entries per flip, repeatedly, until dispatch caught up. Bound the emission to versions that newly entered eligibility on this specific flip: rank 0 (the displaced version, for the NoncurrentDays clock) plus rank == rule.NewerNoncurrentVersions for each active count-gated rule (the version that just crossed from kept to expired). Bootstrap still owns full backfill for versions that were already over-threshold. Adds a regression with 6 versions and NewerNoncurrentVersions=2: asserts only the rank-2 entry that just crossed fires, not the already-over-threshold rank-3/rank-4 entries. * fix(s3/lifecycle): suppress pointer-transition expansion when newID missing routePointerTransitionExpand defaulted latestPos to 0 if newID wasn't found in the listing. That made the actual newest sibling latest against the pointer's intent, then misranked every other version. A race between the pointer write and the version write could land us there. Default latestPos to -1, set it only on a real match, and suppress the expansion when the search misses. Bootstrap repairs state on the next walk. The NewerNoncurrentVersions retention test was setting only lookupEntry, so Route never reached the expansion path it claimed to exercise. Repoint to listVersions and assert ListVersions was consulted while LookupVersion was not. Adds a regression covering the missing-newID suppression directly. * fix(s3/lifecycle): include bare null version in pointer-transition routing Bootstrap models the bare-key object as a "null" sibling alongside .versions/ children, but the live pointer-transition path didn't. Two cases lost: 1. oldID == "" was treated as "nothing displaced". A pre-versioning bare object becomes noncurrent when the first versioned PUT lands and the pointer flips to a real id, but live routing skipped it and waited for the next bootstrap. 2. The expansion path's ListVersions returned only .versions/ children. With a bare null in the picture, the noncurrent ranks were wrong, so NewerNoncurrentVersions could keep the wrong versions and delete the right ones (or vice versa). SiblingLister grows LookupNullVersion(bucket, key) returning the bare entry plus an explicit-null flag (matches the bootstrap shape). filerSiblingLister implements it via util.NewFullPath + filer_pb.LookupEntry. routePointerTransitionDisplaced: oldID == "" now consults LookupNullVersion. When the bare entry exists, route it as VersionID="null" against the LOGICAL key. routePointerTransitionExpand: collect .versions/ children plus the null entry into one sibling slice before sorting and ranking. The threshold-crossing logic now sees the same N-version set that bootstrap would compute. Three new tests: oldID == "" with no null is a no-op (one null lookup, no version lookup); oldID == "" with a bare null schedules NoncurrentDays as VersionID="null"; expansion with a bare null between .versions/ siblings places null at its mtime-correct rank and only that rank-N entry fires. * fix(s3/lifecycle): atomic listPageSize so test cleanup doesn't race KickOffNew dispatches walks via `go b.walkBucket(...)`. A test that finishes before its goroutines drain leaves them running into the next test's t.Cleanup, which mutates listPageSize. -race spots the read/write collision intermittently. Convert listPageSize to atomic.Uint32; tests use Load/Store. No production semantics change. * fix(s3/lifecycle): null becomes latest when suspended PUT clears pointer The router treated newID == "" as if the cached ExtLatestVersionMtimeKey were still authoritative — but that cache holds the displaced version's mtime, written by setCachedListMetadata when the prior version became latest. Using it as SuccessorModTime made NoncurrentDays=30 immediately fire on a 100-day-old displaced version even though it became noncurrent today. When newID == "" the bare null is the new latest. Look it up, substitute its mtime as the successor clock, and substitute "null" as the latestPos target for the expansion path's id match. Both displaced and expand paths now derive the right clock. updateIsLatestFlagsForSuspendedVersioning was the upstream cause of the staleness — it cleared ExtLatestVersionIdKey and FileNameKey but left the cached size/mtime/etag/owner/delete-marker behind. Call clearCachedVersionMetadata so the .versions/ container is consistent with "null is latest". The router-side guard is still needed for older deployments that ran the buggy code, but new writes won't exercise the workaround. Two regressions: 100-day-old displaced under NoncurrentDays=30 with a today-null PUT schedules ~30d out (not immediate); same shape with NewerNoncurrentVersions=2 ranks the null at latest and only the rank-2 entry fires.
