### Fixed
- **Millisecond-TTL keys no longer expire up to 999 ms early (W3).**
`CompactEntry` stored expiry as *seconds* (`ms / 1000` floor) even though

# Releases

## v0.8.2 — 2026-07-20
milestones: none (patch release: the storage-unification campaign W1–W6 + db.rs directory split)
waivers: none new — `XSHARD-READ-01` remains the open GA gap (ROADMAP R4), unchanged from v0.8.1.
evidence: Patch release rolling up the storage-unify stacked train (#396–#401) plus the follow-up `storage::db` directory-module split (#403). **Correctness:** millisecond-TTL keys no longer expire up to 999 ms early — `CompactEntry` stored expiry as seconds (`ms/1000` floor); it is now absolute Unix milliseconds end-to-end with exact `PTTL` readback and exact-ms RDB round-trips (W3, #398). **Unification (behavior-preserving by design, pinned by golden byte-spec tests):** one value codec behind RDB + spill + kv_serde with fail-closed corrupt-score decode and the RDB-DoS count guards now on every decode path (W1, #396); one spill pipeline — sync eviction batches victims into shared files (~N/256 manifest fsync round-trips instead of N per-key, measured every-paired-round faster under maxmemory pressure) and unserializable victims are retained fail-closed instead of spilled empty (W2, #397); one eviction entry point `evict_to_budget` + `EvictionRun`/`EvictionSink` replacing 13 name-encoded variants and 5 reclaim-loop copies (W4, #399); one typed-accessor skeleton via `storage::db_kind` `ValueKind`/`OwnedKind` static-dispatch markers, public per-type methods kept as thin delegators (W5, #400); `AofShardManifest` rename + tier-vocabulary disambiguation docs (W6, #401); `db.rs` (3113 lines) split into `db/{mod,hash_ttl,kv_ops,accessors}.rs`, pure code motion (#403). **Validation:** same-VM A/B (v0.8.1 vs main, alternating rounds) — p=1 SET/GET parity-or-better, eviction-plain faster in every paired round, offload-spill +3%, p=16 within noise; every train PR individually gated (lib suites macOS + VM Linux both runtimes, crash matrix 46/46 + kill-9 suites on the durability PRs, clippy ×2 feature sets); release gate — crash-matrix nightly full matrix + `ITERS=20` soak dispatched on the RC via `workflow_dispatch`, green before tag (soak-first-then-tag). Known flake ticketed: #402 (`test_bg_compact_pool_parallelism`, timing-sensitive, test-only).

## v0.8.1 — 2026-07-19
milestones: none (patch release folding the post-v0.8.0 perf/correctness train + the single-shard tuning preset)
waivers: none new — `XSHARD-READ-01` remains the open GA gap (ROADMAP R4), unchanged from v0.8.0.
