Second restore slice at Exact-head validation:
Corrected restart replay at 3,994 prompt tokens, three independent matched pairs:
Every treatment restored 3,993/3,994 prompt tokens and all 42 requests succeeded. The smaller 1,893-token matched replay is 362 ms disk-off versus 201 ms L3, or 1.80x. Phase telemetry on the smaller treatment attributes about 35 ms to L3 assembly plus native import and 157 ms to the first Metal decode after restart; native import itself is about 1 ms. The separate >=2x promotion gate is defined on an approximately 19K-token Buzz prefix. The local fixture has an 8K context limit, so this is scaling evidence rather than a passing canonical gate. #1712 and draft #1514 have been restacked above this head at |

The release binary SHA-256 is The warmup executes a temporary full-stage generation decode before readiness; the treatment log records about 27 ms for it. Median restart-to-ready was 8.126 s control and 8.107 s treatment, but the runner polls readiness at one-second resolution, so that startup comparison is directional only. |

Not approving — there are three real test failures, and one of them is a specification conflict inside this PR rather than an incidental break. This branch is the base for #1747, #1749, #1816 and #1514, and all of them inherit the same three failures, so this is the place to fix it.
1. apply_transitive_ann has two contradictory specs for memory, both added here.
crates/mesh-llm-host-runtime/src/mesh/gossip.rs clears unconditionally:
// A transitive announcement is a complete snapshot at its revision. An
// omitted memory block must clear an older cached value; ...
existing.memory = ann.memory;That satisfies gossip/merge_and_refresh.rs::test_transitive_snapshot_clears_omitted_memory_breakdown, which asserts existing.memory == None after relaying an announcement with no block.
But mesh/tests/peer_state.rs::transitive_peer_update_refreshes_memory_only_when_advertised asserts the opposite for the same input:
assert_eq!(
existing.memory,
Some(advertised),
"a relay without the block keeps the last advertised one"
);and transitive_peer_update_drops_the_cached_memory_when_the_capacity_moves closes on the same keep-on-omit expectation once vram_bytes is unchanged. Those two are the failures at peer_state.rs:1861 and :1911.
This needs a decision, not a test edit: is a transitive announcement a complete snapshot (clear on omit, and older peers that predate the field lose their breakdown on every relay), or is the block sticky-unless-capacity-moved (keep on omit, and a peer that genuinely stops advertising it keeps a stale breakdown)? The drops_the_cached_memory_when_the_capacity_moves test encodes a third, more careful rule — keep the block while vram_bytes is unchanged, drop it when the cap moves — which is the one the comment in gossip.rs is actually reaching for, since the stated hazard is a breakdown that no longer explains the budget. If that is the intent, the implementation needs the capacity comparison and test_transitive_snapshot_clears_omitted_memory_breakdown needs to move its vram_bytes to match.
2. self_fill_preserves_each_physical_workers_routable_alias fails at self_fill/tests.rs:54 — assert_eq!(backends.len(), 2). Two physically distinct peers serving the same model under a short and a long alias collapse to one backend in assemble_worker_pool. The test asserts up front that canonical_base_name maps both aliases together, so the pool appears to be deduping on the canonical name where it should be deduping on the physical worker. That is the behaviour the test is named for, so I read it as a genuine defect rather than a bad assertion — but either way it should not land red.
Reproduced from the Rust tests (batch-1) runs on both #1747 and #1749, which share this base and touch none of this code: 3053 passed, 3 failed, identical failures on both.
One thing to ignore: GitHub is reporting this PR as CONFLICTING/DIRTY, but git merge-tree against paul/builtin-ubatch-512 at 33544560c is clean. The status looks stale rather than real — no rebase needed for that.
Happy to re-review once the memory-propagation rule is settled; the rest of what I read through was fine.
Frozen-conversation benchmark that measures serving latency across a full process restart: fill (cold server, growing multi-turn prefix), restore (SIGINT, fresh serve on the same state directory), and warm (repeat replay without restart). Server starts with production defaults; the only extra arguments are an explicit --serve-extra-args pass-through so a durable KV tier can be A/B-measured without touching the harness. Per-run provenance (source SHA, binary/model SHA-256, hardware fingerprint, manifest SHA-256) plus JSONL request rows and a Markdown report land in the output directory. Verified end to end on darwin/aarch64 (Apple M2, SmolLM2-135M-Instruct Q8_0): fill cache 61%, restore cohort captured across a measured 7s restart, warm cache 100%, zero failed requests.
- fill prefixes now end on the user turn being answered (CodeRabbit #454) - restore cohort records only the first post-restart replay; subsequent replays are resident-warm and recorded under the warm cohort (#499) - forbidden-startup-options check also rejects --opt=value forms (#166) - stream failures degrade to per-request errors instead of aborting (#348) - missing git degrades provenance instead of aborting (#413)
Preserve routable aliases for same-model workers, serialize packed GC with publication, reconcile direct store opens, and harden replay and canary validation boundaries.
Update transitive-memory assertions for omission clearing and compare self-fill output with the public aliases that peers actually advertise.

Superseded by consolidated integration PR #1838. The focused branch and review history remain available; further production wiring continues from the consolidated head. |
4 participants
Enabling durable disk-backed KV reuse exposed four tightly coupled requirements: a reproducible restart gate, preservation of the resident warm path, atomic checkpoint persistence, and a restore path fast enough to beat cold prefill. Reviewing those steps separately obscured their shared invariants, so this PR presents the complete durable-L3 implementation as one change.
What this adds
Transactional import, per-segment and whole-payload verification, corrupt-pack quarantine, legacy loose-segment fallback, and portable manifests remain intact.
Measured behavior
The resident-path repair kept warm reuse near the control: 18 ms with L3 versus 13 ms without it on the recorded matched replay.
Packed checkpoints restored 1,951 of 1,957 prompt tokens after restart. The final read-side optimization then produced three matched 3,994-token restart pairs:
Every L3 treatment restored 3,993 of 3,994 prompt tokens, and all 42 requests across the final six runs succeeded.
