* fix(s3/lifecycle): reader handles bare /buckets parent and pre-normalizes prefix
extractBucketKey accepted /buckets/ but rejected /buckets (no trailing
slash); some delete events emit the bare form, so bucket-root events
were silently dropped. Pre-normalize BucketsPath once on Run instead
of recomputing per event.
* perf(s3/lifecycle): pool sha256 hashers in ShardID
ShardID runs on every meta-log event before the shard filter; a fresh
sha256.New per call produces measurable allocator pressure under load.
sync.Pool reuses hashers across calls.
* fix(s3/lifecycle): router skips hard deletes and missing-attribute events
A hard delete carries no schedule-relevant state — Expiration would hit
NOOP_RESOLVED at dispatch and ExpiredObjectDeleteMarker fires from a
Create on the latest version. Skip rather than burn a schedule slot.
Missing Attributes leaves ModTime at year 0001, which makes
ExpirationDays fire immediately at dispatch. Skip the event instead.
Drop the unused 'versioned' parameter from buildObjectInfo; the
dispatcher's identity-CAS handles version drift in Phase 5.
* fix(s3/lifecycle): EntryIdentity.MtimeNs holds true nanoseconds
Both computeEntryIdentity (server) and buildIdentity (router) wrote
entry.Attributes.Mtime (seconds) into a field named MtimeNs. The CAS
worked because both sides agreed, but the encoding contradicted the
field name and would break if either side later started using true
nanoseconds. Combine Mtime*1e9 + the FuseAttributes.MtimeNs nanosecond
component on both sides; the test was updated to match.
* fix(s3/lifecycle): dispatcher distinguishes ctx cancel from transport errors
A canceled or deadline-exceeded RPC is shutdown, not a transport
failure: re-queue the Match at its original DueTime with no retry-budget
burn so a quick restart can't escalate it to BLOCKED.
* fix(s3/lifecycle): reader fallback prefix normalization mirrors Run
The fallback path that builds prefix from r.BucketsPath when
bucketsPathSlash is empty (test-only entry into extractBucketKey) was
appending an unconditional '/', producing '//' if BucketsPath already
ended with one. Use the same normalization Run does.
* fix(s3/lifecycle): ObjectInfo.ModTime carries the nanosecond component
ModTime dropped FuseAttributes.MtimeNs, leaving ExpirationDays one
nanosecond off relative to EntryIdentity.MtimeNs. Pass both to
time.Unix so the precision matches the CAS witness.
feat(s3/lifecycle): shard-aware meta-log reader
- ShardCount=16; ShardID(bucket,key)=top-4-bits of sha256(bucket||/||key)
- Reader subscribes via SubscribeMetadata starting at Cursor.MinTsNs(),
filters events by shard, emits to caller-owned Events channel
- Cursor: per-(shard, ActionKey) position with monotonic Advance, Freeze
for blocked actions, MinTsNs for subscription resume
- Persister interface with InMemoryPersister for tests; filer-backed
impl lands with the worker integration
