release(v0.8.0): One Storage Kernel GA — kill-9-lossless on every plane + 10× RAM datasets

[pilotspacex-byte]

Release prep — v0.8.0

Version bump 0.7.1 → 0.8.0 (Cargo.toml + Cargo.lock), CHANGELOG [0.8.0] — 2026-07-16 roll-up, RELEASES.md ledger entry, ROADMAP v0.8.0 section flipped to SHIPPED (all 6 items ticked; exit-criterion wording corrected 42 → 46 cells).

Headline evidence

• CRASH-02: 46-cell cross-plane kill-9 matrix green ungated (zero red_guard sites), wired into scheduled CI — nightly full matrix + Saturday ITERS=20 soak (ci(durability): wire cross-plane crash-matrix into scheduled CI (v0.8 item 4) #352)
• MEM-10X-01: G2 re-run on real disk (docs/perf/2026-07-16-g2-10x-ram-rerun.md, docs(perf): G2 10×-RAM re-run report — v0.8 storage-kernel close-out evidence #356) — spill 236K → 840 files (perf(storage): batch spill segments — oversized values share batch files, ~129× fewer heap files (v0.8 item 3) #350); used_memory 1.00× cap with ≤5s post-restart drain (fix(storage): truthful used_memory under disk-offload — RSS→logical ledger, stub-only recovery, replay demote (task #56) #349); cold-GET-during-spill tail 1,910 → 205ms
• Also in the train: vector auto-merge CPU-livelock fix (fix(vector): exponential backoff for rejected auto-merges — GraphUnion CPU livelock #353), recall-canary CI offload (ci(perf): move heavy recall benchmarks to nightly — per-PR Check tail cut 6-24 min #354), task P1-6: DiskANN uring_search swallows I/O errors → silent recall corruption #49 audit-close (docs(roadmap): task #49 atomic-write sweep — audit closes it, no code change needed #347)

Tag gate (soak-first-then-tag)

Both crash-matrix modes dispatched on RC 82752af5 (main): run 29474511124 (nightly full matrix) + run 29474515215 (soak ITERS=20). Merge holds until both are green.

Disclosed follow-ups (non-blocking)

• task feat(commands): ZSet 6.2+ additions (ZRANGESTORE, ZDIFF, ZUNION, ZINTER, ZINTERCARD, ZMSCORE, ZRANDMEMBER, ZMPOP) #59 read-vs-spill fairness (205ms tail, goal <10ms)
• issue DBSIZE under-reports logical keys under disk-offload (counts resident only) #355 DBSIZE counts only resident keys under offload
• restart time bounded by AOF-rewrite cadence (16.9s at 3.3GB unrewritten incr AOF)

Warning

Review limit reached

@pilotspacex-byte, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 8 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
