perf(kv): keep exact-state recording off inference path

[michaelneale]

Summary

• skip export, hashing, and disk work when the complete exact-page identity is already present; an identical repeat only refreshes LRU recency
• move first-time exact-state hashing and archival onto one bounded background worker per stage
• fail open when optional recording or telemetry contends: inference never waits for the cache worker, and a full one-item queue drops optional work
• expose queue pressure and separate lookup/reconstruction/native-import timings
• route disk-cache warnings through structured mesh_llm_events::emit_event output and retire the three console-print ratchet entries

Why this does not write forever or fill the disk

The new worker changes when a genuinely new page is recorded; it does not remove any storage limits.

1. Identical prefixes do not rewrite. Before native state export, record_exact_state checks the full content/config-derived page identity in RAM and on disk. If found, touch only updates LRU metadata and returns. Concurrent attempts for the same page are also coalesced by the in-flight page-id set. The disk tier independently refuses store when that page id already exists.
2. Work is bounded. Each stage has one worker and a sync_channel(1). Admission uses try_send; if that single slot is occupied, optional recording is dropped rather than blocking inference or growing memory. records_queued, records_dropped, and records_pending expose pressure.
3. Bytes are bounded node-wide and per stage. Automatic policy is 20% of currently free space, capped at 64 GiB, and the tier is disabled below the 16 GiB free-space floor. An explicit budget is also refused unless that budget plus the 16 GiB reserve is free. Stage reservations share the node budget rather than each claiming it all.
4. The tier enforces its cap. It LRU-evicts until bytes <= max_bytes, and rejects a single page larger than the whole tier instead of evicting everything for it.
5. Crashes/concurrency do not leak an unbounded second copy. A cache directory has a nonblocking exclusive owner lock; a second process declines that tier. Page and index publication use temp-file + atomic rename, and crash-left temp/orphan files are reclaimed at next open. Payload and interpretation metadata are checksummed before reuse; corrupt entries are quarantined.

Relevant implementation: crates/skippy-server/src/kv_integration/{exact_state.rs,mod.rs,config.rs,disk_budget.rs} and crates/skippy-cache/src/{exact_state.rs,disk_tier.rs}.

Scope / resource rationale

The PR is now 10 files, +592/-120 against current main; the accidental generated SDK/resource commit is gone. The larger pieces are the bounded record queue/worker, its deterministic lifecycle tests, nonblocking exact-cache paths, counters/timing telemetry, the event dependency, and the regenerated console-print ratchet. No UI/SDK generated resources are part of this diff.

Verified at committed HEAD

Commit ec79904708ee9f9fbd0ba5c166f0975bcc2a42ee:

• cargo run -p xtask -- repo-consistency no-console-print --regen — passed; the three legacy eprintln! entries were removed
• cargo test -p skippy-server --lib — 493 passed, 0 failed, 3 ignored
• deterministic coverage includes existing-page touch/no replacement, full queue drop, disconnected worker, pending/in-flight lifecycle, busy exact-state touch, busy disk telemetry, poisoned lock, disk LRU budget enforcement, oversized-page rejection, exclusive directory ownership, checksum quarantine, and crash-temp reclamation

The macOS linker printed deployment-version warnings during the package test, but the suite completed successfully.

Real model evidence and remaining product gate

A local Qwen3.8-27B cold/exact-repeat/changed-tail run on the patched branch produced valid OK, OK, YES responses. The exact repeat reported 21,022/21,023 cached prompt tokens and completed in ~0.139s. The changed-tail request reported 20,864/21,023 cached prompt tokens, only 158 suffix-prefill tokens, ~1.187s prefill, and ~1.799s wall time. These artifacts are kept outside the PR tree.

That run predates the final structured-warning commit, so it is supporting model evidence, not claimed as committed-HEAD Buzz certification. I am rerunning the exact commit through the authenticated Buzz agent/channel path and will add the observed events plus queue/dedupe telemetry before asking for merge or a human hand-test.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 3b2fc

The PR moves exact-state recording off the inference path, but the current implementation can still delay restoration while recording holds the cache lock and can admit more pending work than the configured bound under concurrent requests. These create concrete latency and resource-control risks, so merge should wait for fixes or explicit owner acceptance.

1103-1106: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

The record telemetry now reports queueing but keeps the wording of storage.

Two attributes changed meaning without changing name:

• The decision label stays {decision_prefix}_recorded (line 1089), but the arm now returns true for a queued record. A queued record can still fail to become resident: ExactStateCache::record removes the entry it just inserted when the payload exceeds max_bytes (crates/skippy-cache/src/exact_state.rs lines 347-354). A dashboard that counts _recorded will over-count.
• skippy.exact_cache.stored is still emitted on the other record path (line 804-807), but record_exact_state now hardcodes stored: false (crates/skippy-server/src/kv_integration/exact_state.rs line 233). That attribute is therefore always false, which reads as "the cache stopped storing".

Rename the label to _queued, and either remove skippy.exact_cache.stored from the asynchronous path or let the worker report the real outcome.

82-83: 🚀 Performance & Scalability | 🔵 Trivial

Consider making the queue depth configurable and alerting on the drop counter.

sync_channel(1) gives one buffered record plus one in the worker. A single stage that serves concurrent requests will hit TrySendError::Full often, and each drop discards a completed export. The new skippy.exact_cache.records_dropped and records_pending attributes expose this, so the effect is measurable.

Read the depth from the stage cache config, and alert when records_dropped grows relative to records_queued.

- Around line 82-83: Make the exact-state record queue capacity configurable
through the stage cache configuration instead of hard-coding sync_channel(1),
while preserving the existing worker behavior. Use the exposed records_dropped

relative to queued records.
- Around line 46-112: The from_config method is overly large because it embeds
exact-state recorder setup and the worker closure. Extract that block into a
helper such as spawn_exact_state_recorder, returning the record sender and the
queued, dropped, and pending counters (plus any required shared handles), then
use the helper from from_config while preserving existing worker behavior and
staying within the configured Clippy line-count limit.

Add a keyboard-accessible provider reorder path. Provider ordering currently relies only on native pointer drag-and-drop; the items are not keyboard-operable and the drag handle is not an accessible control. Add Move up/Move down controls or implement an equivalent keyboard-sortable interaction, then regenerate the SDK bundles.

Use matching provider identities in the policy editor. The reserves page supplies provider names such as Vast.ai and RunPod, while the policy editor initializes providerOrder with category labels such as LAN, Bare metal, and Cloud. The initial ordering therefore cannot resolve the rendered providers and may show incorrect or custom entries. Use shared provider IDs or normalize both sides consistently, then regenerate the SDK bundles.

Bound attachment resources before reading file content.

onAttach accepts every selected file. P, I, tt, and nt load complete files into memory. F decodes an image before it applies the 512-pixel resize limit. A large multi-file selection or an image decompression bomb can block or terminate the console tab.

Enforce attachment-count, byte-size, and decoded-image-dimension limits before calling P or arrayBuffer. Show a rejection message for files that exceed the limits. Apply the fix in the canonical console source and regenerate each SDK bundle.

Guard nested runtime payload fields.

At Line 1, Be, R, and Ke use expressions such as e?.metrics.samples, e?.slots.slots, and e?.slots.error. These expressions guard only e. A non-null payload without metrics or slots throws a TypeError. Qe calls these helpers for live runtime data, so the node drawer can crash instead of showing the unavailable state. Use e?.metrics?.samples, e?.slots?.slots, and e?.slots?.error.

Do not expose preview-only actions for live nodes.

When ReservesPage is in live mode, it passes wakeable_nodes into je. je still handles wake, retry, and dismissal by mutating local React state. Its confirmation text states that no backend request is sent. Users can see a node change locally without changing the live node.

Disable these actions in live mode, or connect them to live backend callbacks and reconcile the returned status.

Do not block restoration behind background recording.

The worker locks exact_states while it records and hashes a large payload. This blocking lock() makes restore_exact_state wait on that worker during inference.

Reserve the pending slot atomically before export.

has_exact_state_record_capacity only reads the counter. Two producers can both observe zero, export their runtime state, and then enqueue. If the worker receives the first record before the second send, both records remain pending despite EXACT_STATE_RECORD_CAPACITY == 1.

Replace the load-plus-fetch_add flow with a compare-and-swap reservation before export. Increment records_dropped when reservation fails. Release the reservation on export failure, send failure, and worker completion.
