* fix(daemon): harden model state ownership
Keep ModelPoolConfig single-defined and serialize telemetry snapshots to avoid ODR drift and torn concurrent reads.
* refactor(daemon): consolidate ingest pollers
Require the wake-timer contract so every post-ingest stage shares one event-driven poller configuration.
* refactor(daemon): unify repair execution
Share admission, operation ordering, cancellation, progress, and result aggregation between synchronous and asynchronous repair paths.
* refactor(daemon): unify runtime tuning
Resolve startup and reload settings through one typed path so parsing, precedence, and range validation cannot drift.
* refactor(daemon)!: remove dead IPC surfaces
Delete unreferenced framing, cancellation, and compatibility paths while keeping the active streaming protocol intact.
BREAKING CHANGE: callers using connectAsync or legacy MessageFramer and FrameReader helpers must migrate to connect, frame_message_into, feed, and get_frame.
* refactor(daemon): hide test hooks
Preserve test-library linkage without exposing daemon-only probes through production headers or external symbols.
* fix(daemon): avoid replaying successful adds
A fresh-connection transport retry reuses the response handler. Clear its stale EOF error when the retry returns a valid add response so the outer retry loop does not enqueue the document again.
* bench(ingest): enforce lossless pipeline runs
Separate admission, storage, drain, enrichment, and searchability timing. Decision-grade plans now reject drops, duplicate processing, incomplete pipelines, and experiment identity drift.
* bench(search): expose cold seed ingest timings
Pair generalized-memory quality arms with admission, storage, drain, searchability, and enrichment timing from their shared cold seed. Keep the observation distinct from repeated throughput measurements.
* perf(ingest): batch deferred content indexing
Directory ingestion already schedules content work through post-ingest. Avoid duplicate inline indexing and coalesce normal-priority trickles within a bounded window.
* feat(metadata): expose insert writer metrics
Separate queue, batch-apply, and transaction time so ingestion runs can attribute connection pressure without changing write semantics.
* fix(daemon): retry transient refused connects
The daemon socket can be bound before its listener is ready during startup. Reuse the existing bounded retry budget for that refusal window.
* bench(ingest): attribute submission path costs
Decision-grade runs need stable coalescing identity and separate queue, apply, transaction, and estimated connection-wait costs.
* perf(ingest): batch durable document storage
Commit chunks, manifests, references, and metadata in bounded batches while preserving publication only after durable reference success.
* perf(ingest): coalesce bulk post-processing
Use a 16-item bulk cap while keeping latency-sensitive daemon ingestion on the existing four-item priority quota.
* bench(ingest): record post-ingest batch size
Include the effective cap in metrics and experiment identity so runs with different batching policies cannot be compared as one system.
* perf(ingest): batch queued storage waves
Preserve single-document fallback semantics and execute inline when the coordinator has one worker to avoid self-deadlock.
* perf(ingest): route bulk enrichment batches
Keep quota-sized interactive groups on the RPC lane while sending larger lossless groups through bounded coalescing.
* test(daemon): initialize task fixtures
* perf(ingest): batch post-ingest dispatch
* perf(ingest): widen directory storage waves
Borrow from a full wave when one document would otherwise fall through to single-document storage.
* perf(storage): bound batch writer fanout
Reuse a fixed worker set so batch size no longer creates one thread and payload copy per object.
* perf(ingest): align storage batch drains
Dispatch one configured batch through storage so intermediate waves do not fragment downstream metadata work.
* fix(ingest): commit metadata state atomically
Fold first-version, extracted-title, and embedding-completion state
into existing transactions.
Read committed extraction state so duplicate-content tasks cannot
double-count corpus counters.
* bench(ingest): measure production submission
Drive pipelined files through DocumentIngestionService.
Export dispatch, fingerprint, and enqueue costs through xplan.
* fix(xplan): preserve native failures
Report child signals and bounded stderr before readiness checks so
assertions are not masked as missing traces.
* fix(daemon): preserve embedding success hashes
* fix(daemon): serialize pooled socket shutdown
* fix(daemon): harden batch publication shutdown
* fix(storage): use compat jthread shim
* fix(daemon): avoid poller template shadowing
* fix(search): keep vector pipeline test enabled
* fix: harden shutdown and fallback paths
Demote expected shutdown SQL interruptions, ignore readonly FTS integrity noise, avoid stopped-executor socket hangs, and preserve metadata writer fallback outcomes.
