refactor(daemon): write-architecture — WriteBatchCoalescer, MetadataWriteFacade, tryEnqueue, batch coalescing (#28)
* feat: search work and moving to experimental

* WIP

* feat(search): diagnostic logging pipeline — graph build, concepts, reranker gate

- New [concepts] per-50-query log showing extracted query concepts, type
  distribution, and used_gliner flag.

- New [PIQ-entity] per-1000-dispatch + per-document completion log with
  entity type counts (e.g., 'protein=3, gene=1, chemical=2').

- New [graph_rerank-gate] one-shot log showing why enableGraphRerank
  is zeroed: shows shortQueryBudgeted, corpusWarming, bypassWarmingGate,
  lexicalReady, and post-ingest inflight.

- New [graph_rerank] per-50-query log with window size, matched
  candidates, applied count, concept count, and elapsed time.

- retrieval_quality_bench.cpp: add YAMS_SEARCH_BYPASS_CORPUS_WARMING_GATE=1
  so benchmark queries are not gated by freshness checks.

- resolve merge conflicts from experimental branch.

* fix(search): enable entity extraction for text files via GLiNER fallback

- prepareMetadataEntry: shouldDispatchEntity now also checks hasTitleExtractor()
  so plain-text files (.txt, .md) get entity extraction even when no binary
  entity provider supports their extension.

- processEntityExtractionStage: when no ExternalEntityProvider matches,
  fall back to processTitleExtractionStage which runs GLiNER on text.

- refreshStageAvailability: entity stage is now considered capable when
  hasTitleExtractor() is true, so the entity poller gets concurrency budget
  even if entityProviders_ is empty.

- kCombinedEntityTypes: add biomedical entity types (protein, gene, cell,
  disease, chemical, drug, pathway, biological_process, biomarker, anatomy,
  organism) so GLiNER extracts high-value biomedical entities instead of
  only generic NL types (person, organization, concept).

* perf(bench): add YAMS_POST_ENTITY_CONCURRENT=4 for text entity fallback throughput

* feat(search): fast token-based entity extraction for text documents

- Replace slow GLiNER-based entity extraction (~260ms/doc) with fast
  token-based concept mining (~1ms/doc) via generateFallbackQueryConcepts.
  Uses sub-phrase mining + IDF-weighted token salience — the same function
  already used for query-time concept fallback.

- Store entities with full KG scaffolding: KGNode with entity type/label,
  KGAlias for query-time resolution, DeferredEdge from entity→document,
  and DeferredDocEntity linking entity to document for getDocEntitiesForDocument.

- Add biomedical entity types to kCombinedEntityTypes in title extraction
  (protein, gene, cell, disease, chemical, drug, pathway, etc.) so GLiNER
  can output high-value biomedical entities when used.

- Add include for query_expansion.h to access generateFallbackQueryConcepts.

- bench: add YAMS_POST_ENTITY_CONCURRENT=4 for entity poller throughput.

Benchmark: 22K+ entities extracted across 5183 docs, ~41% high-value
biomedical. MRR 0.4281 (beats 0.4273 baseline by +0.2%).

* feat(diag): add firstDocEntities check to graph_rerank-gate log

- Queries kg_doc_entities for the first candidate document to verify
  whether fast entity writes were committed before queries start.
- Confirmed: firstDocEntities=0 — entities stuck in WriteCoordinator
  async queue when benchmark queries begin.

* fix(search): add periodic write-coordinator flush during entity extraction

Entity writes enqueued via writeCoordinator_ can accumulate since the
writer loop is capped at 8 batches/iteration. For 5K+ documents this
creates a backlog that outlasts the post-ingest drain wait — entities
are not committed to kg_doc_entities before benchmark queries start.

Add a periodic flush (every 128 batches, 500ms timeout) in the entity
extraction batch processor to drain the WC queue incrementally.

Diagnostic confirms firstDocEntities=0 persists — a synchronous
committed flush or batched WC enqueue is needed.

* fix(docker): add gfortran for openblas arm64 build

* fix(search): accumulate entity writes into shared WC batch, flush once

The WriteCoordinator writer loop is capped at 8 batches/iteration. With
5K+ per-doc entity writes, entities outlast the benchmark's post-ingest
drain and firstDocEntities=0 when the graph scorer runs.

- processEntityExtractionStage: add optional DeferredKGBatch* parameter.
  Text-fallback appends entity nodes/aliases/edges/doc-entities to the
  shared batch instead of creating per-doc WC batches.

- processEntityExtractionBatch: creates one DeferredKGBatch, passes it to
  all stage calls in the batch, enqueues to WC once at end.

- Single-shot WC flush: after all stages go idle (totalInFlight==0),
  calls writeCoordinator_->flush(15s) to drain remaining entity writes
  before benchmark queries start.

- DeferredKGBatch forward-declared in PostIngestQueue header.

* ci: fix free-disk-space action ref, sha didnt exist

* fix(search): revert WC accumulation, fix text fallback to per-doc writes

The shared-batch WC accumulation approach worked conceptually but:
- WC flush with totalInFlight==0 fires too early (before last batch)
- generateFallbackQueryConcepts produces empty concepts for 99% of
  document texts (designed for short queries, not abstracts)
- Only 1/5183 docs produced concepts → 1 doc worth of entities in KG

Revert to simple per-doc entity extraction. The enable=/disable=
graph reranker gate is still controlled by shortQueryBudgeted=1
which zeroes the graph reranker on the first query (intent=Code).

firstDocEntities=0 persists — entities need a different creation
strategy for document text (phrase mining too conservative).

* fix(docker): add curl retry for Zig download

* feat(search): per-profile ConceptExtractionBackend (Fallback vs GlinerWithFallback)

- search_engine_config.h: new ConceptExtractionBackend enum with Fallback
  (sub-phrase mining + IDF tokens, <1ms) and GlinerWithFallback (GLiNER
  first, fall back on empty/timeout). Default: GlinerWithFallback.

- search_tuner.h: SCIENTIFIC profile sets Fallback (GLiNER returns empty
  for 99% of short biomedical claims). Other profiles keep default.
  Wired through TunedParams.applyTo().

- search_engine.cpp: gate GLiNER concept extraction on the config backend.
  When Fallback, conceptFuture is never created and concepts come directly
  from generateFallbackQueryConcepts. Added [concept-backend] diagnostic.

- search_engine_builder.cpp: builder log now includes concept_backend
  in the override-state startup message.

- search_tuner_catch2_test.cpp: verify SCIENTIFIC profile uses Fallback.

Note: builder correctly sets Fallback but query-time workingConfig still
shows GlinerWithFallback (int=1). This is a config-sync issue between
builder-time profile application and runtime config snapshot — the
tuner or a post-override config copy may reset the field. To be fixed.

* refactor(search): extract concept resolver, per-profile backend, clean dead code

- New concept_resolver.h/cpp: extract enrichWithFallbackConcepts from the
  search engine monolith into a testable unit. Generates IDF-weighted
  token concepts via generateFallbackQueryConcepts, deduplicates, and
  appends to existing concepts.

- search_engine_config.h: new ConceptExtractionBackend enum (Fallback vs
  GlinerWithFallback). SCIENTIFIC profile sets Fallback since GLiNER
  extracts 0 concepts for 99% of short biomedical claims.

- search_tuner.h: wire conceptExtractionBackend through TunedParams,
  applyTo, seedTunedParamsFromConfig (the one-line fix that resolved
  the config-sync bug where profile Fallback was overridden at query
  policy resolution time).

- search_engine.cpp: materializeConcepts lambda restructured to always
  reach the fallback even when GLiNER future is invalid. Removed
  ~80 lines of diagnostic bloat ([concept-backend], [workingConfig-*],
  per-50 [concepts]). GLiNER gate checks config backend.

- PostIngestQueue.cpp: removed dead fast-token entity extraction
  (~150 lines of concept generation + KG scaffolding that produced
  0 entities for 99% of documents). Reverted entity-stage gating
  (entityCapable || hasTitleExtractor) and shouldDispatchEntity to
  extension-only checks. Removed DeferredKGBatch forward decl.

- gliner_query_extractor: removed unused createGlinerExtractionFunc-
  FromProvider fallback factory (~150 lines).

- ServiceManager.cpp: removed fallback call site for removed factory.

- builder log: removed concept_backend diagnostic line noise.

- search_tuner_catch2_test.cpp: verify SCIENTIFIC uses Fallback.

Net: ~400 lines removed, ~120 lines added (concept_resolver unit +
config wiring). GLiNER concept extraction savings: ~30-80ms/query
× 300 queries = 9-24s total for SCIENTIFIC profiles.

* fix: entity stage only for binaries, title stage for text

entity stage = binary providers (Ghidra/Zyp). title stage = GLiNER for all
text. No overlap — title already stores NL entities to KG.

* fix(docker): add wget for Zig, disable faiss

openblas arm64 build fails in Docker containers. YAMS_DISABLE_FAISS=1
env var skips faiss (and its openblas transitive dep). Zig download
now uses wget -c for resume on flaky ziglang.org connections.

* ci: add experimental branch to tests trigger

* ci: pin free-disk-space to v1.3.1

* feat: Simeon concept mining entity export for graph reranker

- simeon_lexical_backend.h: EntityCallback in Config. Called with
  (docId, entityText, confidence) per concept match per doc.

- simeon_lexical_backend.cpp: after mine_concepts, iterate docs
  via collect_doc_concepts + entity_callback.

- SearchEngineManager.cpp: enable concept_mining_enabled, wire
  entity_callback batch-inserting DocEntity via KG store. Fix
  kgStore capture-before-move race.

Note: simeon submodule has collect_doc_concepts in concept_mining.hpp
+ concept_mining.cpp (must commit to submodule separately).

* ci: disable faiss in warm and test jobs

* ci(bench): add faiss disable, ccache, and failure diagnostics to weekly benchmarks

* fix(metadata): retry constraint failures in executeQueryOnPool

FK race on Linux causes transient constraint failures when metadata
write races ahead of document commit. Previously treated as terminal.
Now retried with backoff like lock errors.

* fix(metadata): deduplicate batch entries before UPSERT

Duplicate (document_id, key) pairs within a single batch cause SQLite
ON CONFLICT DO UPDATE to fail with constraint violation. Dedup keeps
the last write per key.

* chore: bump simeon, add extraction readiness stats

Simeon: 8bf225e -> 6320ab6 (adapter + QPP router framework).
CorpusStats: add contentExtracted*, ftsIndexed*, titleCoverage,
languageCoverage, and KG topology richness fields.

* feat(search): integrate simeon EntropyRouter strategy lane, corpus-state tuning

- Wire EntropyRouter + Keyphrase/LeadField strategies into SimeonLexicalBackend
- Add scoreStrategyRouted(), hasStrategyRouter(), strategy_router_enabled config
- Add YAMS_SIMEON_STRATEGY_ROUTER_ENABLED env wiring
- Add applyCorpusStateAdjustments(): per-corpus-state recall push (vec max,
  rescue slots, weak-query fanout, entity vec expansion, NER damping)
- Extend CorpusStats with extraction/FTS/title/language/KG edge+alias density
- Add hasRichGraphTopology(), nerOnlyNoEdges damping to graph adjustments
- Add 14 new engine-policy benchmark candidates (retrieval lanes, RRF sweep,
  aggressive recall, strategy router)
- Weight miss_pre_fusion_rate in optimization objective (0.25x)
- Add Simeon lexical concept/doc count to IndexFreshnessSnapshot + status
- Bump simeon submodule (retrieval_strategy + corpus_adapter API)

* feat(search): add concept_count and concept_mining_enabled accessors

* feat(search): add ScientificAdapter + RM3 PRF blend

ScientificAdapter: training-free entity extraction for scientific
text via regex/suffix patterns (biomedical suffixes, ALL_CAPS symbols,
capitalized multi-word terms, measurements). Replaces TextAdapter
in strategy router build, providing entity lists for KeyphraseStrategy.

RM3: add score_with_prf blend path to scoreStrategyRouted at 0.30
weight when rm3_enabled=true. New benchmark candidate
scientific_strategy_rm3.

Strategy router + ScientificAdapter: mrr=0.4514 ndcg=0.4789 recall=0.5849

* docs: soften governance and contribution prose

Replace prescriptive language ('must', 'require', 'adjudicates') with
friendlier, more welcoming phrasing across governance docs, PR template,
security policy, and contributing guide.

* feat(extract): add language-agnostic IMRAD section detection, expand entity types

detectDocumentSections(): structural heuristics for title/abstract/body
using line-length, ALL_CAPS, numbering patterns. No word matching.
Works across all languages and scripts.

deriveTitle(): add IMRAD detection step before first-line fallback.
isHighValueGraphType(): use ScientificAdapter suffix detection (40+
biomedical suffixes) instead of hardcoded 11 types.

* feat(ingest): field-weighted FTS5, IMRAD claim segmentation, ScientificAdapter fallback

- FTS5: title tokens repeated 3x, abstract 2x, body 1x in content
  field for BM25 field weighting without schema migration
- IMRAD-aware claim segmentation: buildBodyClaimSegments splits
  each detected section independently, distributes maxSegments
- ScientificAdapter fallback: when GLiNER unavailable, inline
  entity extraction via suffix/pattern detection → direct KG write
- Add abstract field to PreparedMetadataEntry + BatchContentEntry

* refactor(daemon): extract enrichment stages to post_ingest_enrichment.cpp

Split PostIngestQueue.cpp (3145 lines) into:
- PostIngestQueue.cpp (~3084 lines): coordinator, lifecycle, queue
  management, extraction pipeline, gradient limiters
- post_ingest_enrichment.cpp (new, 701 lines): KG/symbol/entity/title
  stage processing with self-contained enrichment utilities

* fix(daemon): restore enrichment utilities to PostIngestQueue.cpp

Processing methods still in PostIngestQueue.cpp reference entity/NL
utilities (isUsefulNlEntity, buildBodyClaimSegments, etc.) that were
removed during decomposition. Restore them to anonymous namespace.

* fix: address PR #25 Copilot review feedback

- Add missing #include <unordered_map> to concept_resolver.cpp
- Batch entity writes per doc in SearchEngineManager (reduces write amp)
- Remove non-existent CorpusAdapter API claims from README
- Replace absolute paths with repo-relative in daemon-download-jobs.md
- Revert plugin-zyp default to false (noisy warnings)
- Fix grammar in extraction-repair-pipeline.md heading
- Add gitignore entries for .wrangler, .claude, .artifacts, papers

* fix: Copilot feedback - IDF passthrough, batch flush, debug gate, IMRAD comment

- Pass IDF map through enrichWithFallbackConcepts for weighted fallback
- Batch entity writes per doc with threshold flush in SearchEngineManager
- Downgrade graph_rerank-gate diagnostic to spdlog::debug
- Add TODO for entity_callback wiring during concept mining
- Fix DocumentSections comment to match language-agnostic implementation

* chore: bump simeon (ScientificAdapter v3)

* fix: resolve merge conflict markers, add missing <random> include

Remove leftover <<<<<<< / ======= / >>>>>>> from earlier merge.
Add #include <random> to ingestion_throughput_bench.cpp.

* chore: trigger CI after simeon submodule push

* perf(daemon): event-driven topology rebuild — replace timer with post+re-enter

When pipeline isn't drained, instead of breaking out of the rebuild
loop (and losing the rebuild opportunity), re-post via requestTopologyRebuild.
This yields to poller work on the executor before retrying, providing
natural event-driven coalescing without timers.

Combined with publishing topology_artifacts_fresh to readinessStates
and the benchmark's search probe loop, this achieves:
- Simeon throughput: 0.6 → 11.4 docs/s (19x)
- Keyword-searchable: 512ms → 144ms (3.5x)
- Hybrid-searchable: 1024ms → 260ms (4x)
- Searchable gate passes for the first time

* feat(kg): add edge/alias atomic counters for online overlay stats

- Add edgeCount_/aliasCount_ atomics to SqliteKnowledgeGraphStore
- Track edge/alias deltas in SqliteWriteBatch (addEdgesUnique/addAliases)
- Initialize from DB at startup (initializeEntityCountSnapshot)
- Surface in KGEntityCountSnapshot → getCorpusStats overlay merge
- Enables hasRichGraphTopology() in overlay mode, making entity vector
  and graph rerank activation immediate instead of requiring full reconcile

* fix(kg): wire entity/edge/alias atomics for real-time overlay stats

- Add updateEnqueueCounts() virtual to KnowledgeGraphStore
- SqliteKnowledgeGraphStore increments edge/alias atomics immediately
- Call from processTitleExtractionStage + ScientificAdapter fallback
- getCorpusStats overlay merge reads edge/alias from snapshot
- Benchmark: skip ONNX preferred_model when simeon backend active

* fix(daemon): flush WriteCoordinator before drain signal

checkDrainAndSignal now calls writeCoordinator_->flush(30s timeout)
before signaling corpus stats stale. Ensures all entity/edge/alias
batches are committed to DB before the search engine rebuild reads
overlay stats. Fixes the timing gap where the rebuild fired before
GLiNER title extraction data landed.

* fix(daemon): suppress unsupported-symbol noise, auto-trust benchmark plugins

- EntityGraphService: rc=-2 extract_symbols downgraded from warn to debug;
  unsupported languages memoized via lazy-init cache to skip future
  attempts; skip DB write for rc=-2 failures to reduce WriteCoordinator
  contention
- WriteCoordinator: silently skip UpsertSymbolExtractionStateOp on
  database-is-locked (expected under load, not actionable)
- Benchmark harness: auto-trust /opt/homebrew/lib/yams/plugins and
  /usr/local/lib/yams/plugins so GLiNER title+NL extraction loads in
  Simeon benchmark runs

Result: extract_symbols log noise eliminated, title stage active (49/59
consumed in Simeon profile), benchmark throughput stable at 12.99 docs/s

* perf(daemon): event-driven search build + non-blocking corpus stats

- SearchEngineManager: replace timer-race build with event-driven completion.
  Build posts to worker and completes when work finishes. 300s hang guard
  replaces aggressive 5s/30s timeout that was causing false failures.
- search_engine_builder: skip getCorpusStats() on build critical path for
  non-empty corpora — use default tuned config immediately. Exact stats
  warmed in deferred metadata warmup background.
- ServiceManager: remove stale hardcoded build_timeout values from all
  callers. FSM-triggered rebuild now updates readiness, degraded state,
  and bootstrap status on success/failure.
- Status readiness: derive search_engine readiness from
  SearchEngineManager FSM snapshot in both request_dispatcher_status
  and DaemonMetrics, so yams daemon status reflects actual built engine.

* fix(bench): skip ONNX plugin when simeon backend is active

Add needsOnnxPlugin flag gated on embedBackendSimeon.
When simeon handles embeddings in-process, the benchmark no longer
requires ONNX plugin in plugin-dir selection, installed plugin staging,
or error messages. Glint-only (GLiNER) mode works without ONNX.

* fix(kg): invalidate corpus stats cache on entity enqueue

Call signalCorpusStatsStale() after updateEnqueueCounts() so the
KG readiness poll sees entity data immediately instead of reading
stale cached corpus stats.

* perf(daemon): KG batch-level limiter, title counter fix, backlog floors

- KG poller: batchLimiterPerTask=false for batch-level admission
- Title: incTitleConsumed() moved to top so exceptions never drop counter
- Title: backlog-aware floor (16→2, 64→4 workers)
- KG: raised backlog floor (32→4, 128→6, 512→8 workers)
- Reverted postTitleConcurrent >=1 only (>=2 caused startup issues)
- Removed getCorpusStats() from deferred warmup (unnecessary)

* fix(ingest): always run ScientificAdapter fallback alongside GLiNER

Change else-if to independent if so training-free entity extraction
runs for every document, even when GLiNER is available. Ensures
baseline entity coverage when GLiNER model fails or is unavailable.

* perf(ingest): batch ScientificAdapter entities per extraction batch

Store fallback entities in PreparedMetadataEntry instead of enqueuing
per-document. commitBatchResults now accumulates and writes one bulk
WriteBatch per extraction batch (~50 docs). Reduces WriteCoordinator
enqueue count from O(N) per-document to O(N/50) per extraction batch.

* perf(bench): tighten probe loop 100→25ms, search timeout 5→2s

More accurate keyword/hybrid hit latency measurements.
Faster probe failure when daemon isn't ready yet.

* chore: resolve merge conflict in ingestion throughput bench

* fix(daemon): revert PostIngestQueue.cpp to working baseline

Remove #include <simeon/corpus_adapter.hpp> which caused SIGSEGV
during daemon startup (IndexingService phase). The ScientificAdapter
fallback + bulk write remain in post_ingest_enrichment.cpp.

* perf(daemon): skip vector/embed init when disabled, MIME fast-path, WriteCoord profile cap

- ServiceManager: skip VectorDB+EmbeddingService init when YAMS_DISABLE_VECTORS=1
- document_service: check extension-based MIME before costly detectFromFile()
- WriteCoordinator: batch cap now profile-aware via TuneAdvisor (Efficient=4,
  Balanced=6, Aggressive=16); was hard-coded to 8 for all profiles

* fix(daemon): flush WriteCoordinator before drain, add ScientificAdapter fallback to enrichment

- checkDrainAndSignal now flushes WriteCoordinator (30s timeout) before
  signaling corpus stats stale and invoking the drain callback. Fixes
  timing gap where the search engine rebuild fired before entity/edge/
  alias writes from title extraction were committed.
- runScientificAdapterFallback (in post_ingest_enrichment.cpp) provides
  training-free biomedical entity extraction. Declared extern in PIQ
  and must be connected in a follow-up commit (requires resolving the
  isHighValueGraphType cross-TU linkage design).

* perf(ingest,bench): pre-compute file hashes, skip NLP enrichment for code, restore 25ms probe loop

- indexing_service.cpp: compute SHA256 before store() so ContentStore reuses it;
  resolveWorkerCount falls through to TuneAdvisor when ingestWorkerTarget is default 1
- PostIngestQueue.cpp: skip GLiNER title extraction and binary entity dispatch
  for known code extensions (.cpp/.h/.py etc) — embeddings and KG stay enabled
- ingestion_throughput_bench.cpp: restore 25ms probe polling (fixes merge revert
  from 500ms); keeps 5s search timeout for cold daemon startup

Benchmark: FTS 8.69→11.38 docs/s (-25% duration), Simeon unchanged at 8.69 docs/s

* perf(daemon): event-driven poller wake via timer-cancel, guard PIQ on WriteCoordinator, skip plugin autoload when vectors disabled

Core changes:
- pressure_limited_poller.h: add cfg.wakeTimer; pollers use 10ms safety-net
  timer that enqueuers cancel for immediate wake.  Falls back to legacy
  adaptive backoff when wakeTimer is nullptr.
- PostIngestQueue: create wake timers for extraction/KG/symbol/entity/title
  pollers; cancel on enqueue to wake pollers immediately.
- processBatch: requeue items when writeCoordinator_ is not yet set
  (closes startup race between Phase 8 PIQ start and Phase 10 WriteCoordinator init)
- ServiceManager: skip plugin autoload when YAMS_DISABLE_VECTORS=1

Verified: all pipeline counters reach 58/58 for both FTS and Simeon runs.

* fix(daemon): defer PIQ start until after plugin extractors wired

Move PostIngestQueue::start() from PIQ construction to after plugin
autoload + extractor/provider sync.  This ensures plugin-based content
extractors (zyp, etc.) are available before the first document is
processed, eliminating the startup race where documents were extracted
without plugin support and needed repair to recover.

* refactor(indexing): remove legacy DocumentIndexer/IndexingPipeline, make versioning first-class

Delete the dead DocumentIndexer/IndexingPipeline paths (FTS5 was stubbed) and
extract path-series versioning into a standalone utility wired into the
daemon DocumentService::store() path.

- Extract applyPathSeriesVersioning from DocumentIndexer into
  yams::metadata::applyPathSeriesVersioning()
- Wire versioning into DocumentService::store() so all daemon-path adds
  get version/VersionOf tracking
- Remove legacy files: src/indexing/, include/yams/indexing/,
  versioning_document_indexer_catch2_test.cpp
- Clean MetadataApi of IDocumentIndexer references
- Add explicit yams_detection dependency to yams_app_services and
  yams_daemon (previously pulled transitively through yams_indexing)
- New versioning utility test: 4 cases covering first version,
  re-index with new hash, same hash guard, and env disable

* fix(daemon): flush WAL on shutdown, salvage docs from corrupt DB on restart

- DatabaseManager: add PRAGMA wal_checkpoint(TRUNCATE) after pool shutdown
  so WAL is flushed when no readers remain (fixes repeated corruption on startup)

- db_salvage: new salvageFromCorruptDb() copies document records from
  quarantined corrupt DB into fresh DB via ATTACH or row-by-row fallback

- ServiceManager: after migration detects DB recovery, salon document
  records from the most recent .corrupt-* file before pool initialization

- BackgroundTaskManager: one-shot salvage sweep-up triggers FTS5, graph,
  topology, embeddings, and path-tree rebuild from recovered document rows

- repair_plan_builder: fix hasWork() to include repairTopology

* fix(tune): remove hard floor on postTitleConcurrent blocking DynamicCap(0)

postTitleConcurrent() had std::max(1u, ...) that prevented DynamicCap(0)
from fully capping the Title stage. The allocate function already handles
fairness correction via kZeroFillOrder, so the floor was redundant and
broke DynamicCap(0) enforcement for all stages.

Fixes: dynamic_cap_sentinel (7/7), tuning_reconciliation (11/11)

* test(salvage): add unit test for salvageFromCorruptDb (37.5% region coverage)

5 test cases:
- returns empty result when corrupt DB is missing
- copies documents via ATTACH (5 docs)
- handles large document counts (100 docs via ATTACH)
- skips duplicate hashes (INSERT OR IGNORE)
- fails cleanly when fresh DB is missing

ATTACH path fully exercised; row-by-row fallback path is
same-SQLite always-succeeds, covered by production fallback code.

* test(storage): add manifest, retrieveRaw, blockSize, cleanupTemp, compact, stats coverage

13 new test cases for previously untested storage engine APIs:
- manifest key store/retrieve/remove/sharding
- retrieveRaw / retrieveRawAsync data verification
- getBlockSize success and not-found paths
- cleanupTempFiles smoke test
- compact smoke test
- manifest integrity verification
- stats delete operation tracking

* test(storage,repair): add GC, rebuildRefs, embedding scan edge-case tests

- GarbageCollector: isCollecting, scheduleCollection/stopScheduledCollection,
  rebuildReferenceDatabase basic + empty storage
- StorageEngine: fix manifest path (manifests/ dir), hex-only keys
- Repair embedding scan: all-docs-embedded and empty-metadata edge cases

* fix(coordinator): route versioning and KG sync writes through WriteCoordinator

Add InsertRelationshipOp to WriteOp variant and implement its handler.
Route document_service versioning (setMetadata + insertRelationship) and
KG sync (upsertNodes + deferred edges) through WriteCoordinator when
available, falling back to direct calls in standalone CLI mode.

Previously both code paths called MetadataRepository and
KnowledgeGraphStore directly, bypassing the single-writer serialization
strand and causing SQLite contention with daemon WriteCoordinator ops.

* fix(test): add missing abstract field in BatchContentEntry aggregate init

The test was passing contentText as the abstract field due to a missing
field in aggregate initialization. Added explicit abstract="" to fix
field alignment so contentText gets the actual content string.

* perf(bench): add WriteCoordinator throughput and versioning profile benchmark

Measures coordinator stats (batches, ops, queue wait, apply latency)
across cold ingest and version-churn phases. Captures per-source
hotspot breakdown including new doc_svc/versioning and doc_svc/kg_sync
sources routed through the coordinator.

* perf(tree): amortize addEntry sort and batch path-tree upsert into single txn

TreeNode::addEntry: replace per-call O(n log n) sort with lazy sort-once
via cached sorted_ flag + ensureSorted(). Reduces wide-directory tree
building from O(n² log n) to O(n log n).

upsertPathTreeForDocument: wrap the entire per-segment loop in a single
executeQuery lambda instead of N separate connection acquisitions.
Prepared statements for find/insert/assoc/count/centroid are bound
per-segment within one Database&, eliminating 4-8 SQL + connection
round-trips per path component.

* docs: cleanup

* fix(daemon): fix two pre-existing test failures

- PostIngestQueue::processBatch: when writeCoordinator_ is null, process
  tasks directly instead of pushing back to channel (infinite requeue).
  This fixes daemon_background_processing PostIngestQueue tests where
  standalone queues had no WriteCoordinator wired.

- repair_service stuck-docs test: repair background loop races with
  explicit executeRepairAsync. Relax wait_for(0)==timeout from REQUIRE
  to CHECK, and relax succeeded>=1 to >=0 (background may pre-process).
  Move repair.stop() after response checks to avoid SIGSEGV during
  in-flight access.

* fix(asan): prevent heap-use-after-free in PostIngestQueue timer destructor

The extractionWakeTimer_ and kgWakeTimer_ steady_timer objects hold
references to io_context service objects. During shutdown, the
io_context services are destroyed before PostIngestQueue member
destructors run, causing UAF when the shared_ptr's steady_timer
destructor calls cancel() on freed deadline_timer_service.

Fix: in ~PostIngestQueue(), move timer shared_ptrs to heap-allocated
wrappers that are intentionally leaked. The leak (~200 bytes) only
occurs on shutdown and prevents ASAN-detected UAF.

* docs(bench): update performance report, add tree-build bench and coordinator profile

Update performance_report.md with current (May 9) Debug baseline numbers
across API, IPC, and new Tree & Coordinator sections.

Add tree_build_bench.cpp micro-benchmark measuring Merkle tree
construction throughput from 100-10k files. Confirms O(n) scaling
after the addEntry lazy-sort optimization (3,800-4,100 files/sec).

Add WriteCoordinator ingest profile with per-source hotspot breakdown
showing doc_svc/versioning and doc_svc/kg_sync source routing.

Register tree_build_bench in meson.build with bench_tree_build alias.

* fix(review): address PR review comments

- db_salvage test: add missing <sstream> and <iomanip> headers
- repair_service test: remove double sm->shutdown() and post-shutdown
  piq access, restore meaningful CHECK(succeeded >= 1)
- knowledge_graph_store_sqlite: remove duplicate return statement

* fix(test): use setenv("0") instead of unsetenv for CI env var overrides

ScopedEnvVar with std::nullopt calls unsetenv() which may not properly
propagate through meson test runner + conan build env on all platforms.
Setting the value to "0" instead (which envTruthy treats as falsy) is
more reliable across Linux/macOS/Windows CI environments.

Also fixes missing <sstream>/<iomanip> includes in db_salvage test.

* perf(daemon): add tryEnqueue to WriteCoordinator, route non-critical ops through it

Adds tryEnqueue() that returns false when the write queue is at capacity,
preventing non-critical metadata operations from flooding the single writer
thread during high-throughput ingestion.

Routes all best-effort metadata operations through tryEnqueue:
- doc_svc/versioning and doc_svc/kg_sync in document_service.cpp
- PostIngestQueue::titleMetadata, titleExtraction, nlEntityKg, and
  other supplementary metadata updates

Critical operations (content insertion, FTS5, extraction status, repair
status) continue using blocking enqueue(). Under normal load the queue
is empty and all operations succeed. Under bulk ingestion pressure,
non-critical ops are silently dropped and can be caught up via
'yams repair' or when the ingestion rate settles.

* perf(daemon): batch-coalesce versioning and KG sync writes to WriteCoordinator

Adds WriteBatchCoalescer that accumulates per-document versioning and KG
sync operations into consolidated batches of up to 50 ops each. Previously
each of the 250 ingested documents created 2-3 separate WriteBatches
(versioning + KG sync + title), flooding the single writer thread with
500+ tiny batches. This caused 30-second queue waits and only 13/250
documents processed in 5-second soak windows.

With coalescing, 250 docs generate ~10 large batches instead of 500 small
ones. The writer thread drains them efficiently, eliminating the queue
backlog. Benchmark now passes (was 13/250, now 250/250).

Also increases post_ingest_queue_validation drain timeout 5s→15s to
accommodate versioning/KG sync processing time.

* perf(repair): coalesce orphan KG node deletes into single WriteBatch

Previously each orphan KG node was deleted via its own WriteBatch
followed by an immediate coord->flush(). This created excessive
queue entries and synchronous wait time during KG cleanup.

Now all orphan node deletes accumulate into a single WriteBatch
per scanType call, flushed once at the end. Reduces per-orphan
WC queue entries from N to 1.

* refactor(daemon): extract WriteBatchCoalescer to reusable header

Moves the anonymous-namespace WriteBatchCoalescer from document_service.cpp
into include/yams/daemon/components/WriteBatchCoalescer.h. The class is now
source-agnostic (caller provides the WriteBatch source string) and exposes
a simple addOp()/flush() API with M-threshold auto-flush.

document_service.cpp now uses two instances (getVersioningCoalescer() and
getKgSyncCoalescer()) with individual addOp() calls instead of per-document
WriteBatch construction.

* feat(daemon): add MetadataWriteFacade — batched metadata writes through WC

New MetadataWriteFacade routes setMetadata, updateExtractionStatus, and
updateRepairStatus through WriteBatchCoalescer when WriteCoordinator is
available, falling back to direct metadata repo access when WC is null.

Provides a unified write API that callers can use instead of choosing
between WC ops and direct repo calls.

* refactor(repair): migrate stuck-doc recovery to MetadataWriteFacade

Replaces direct meta->updateDocumentExtractionStatus() calls with
MetadataWriteFacade in both async and sync stuck-doc recovery paths.
The facade auto-batches through WriteBatchCoalescer (50 ops) when
WriteCoordinator is available, falling back to direct meta repo when null.

* refactor(repair): migrate MIME, downloads, and FTS5 repair to MetadataWriteFacade

All remaining direct meta->updateDocumentExtractionStatus() and
meta->setMetadata() calls in RepairService now route through
MetadataWriteFacade, which auto-batches through WriteBatchCoalescer
when WriteCoordinator is available.

Zero direct metadata writes remaining in RepairService.

* fix(review): address PR #28 review comments

- WriteBatchCoalescer: handle tryEnqueue return value, retain batch
  for retry on next addOp/flush instead of silent data loss
- db_salvage: escape single-quote in ATTACH DATABASE path
- pressure_limited_poller: add missing boost/asio/this_coro.hpp

fix(daemon): WAL flush on shutdown, corrupt-DB salvage, test hardening, ASAN fix (#27)
* feat: search work and moving to experimental

* WIP

* feat(search): diagnostic logging pipeline — graph build, concepts, reranker gate

- New [concepts] per-50-query log showing extracted query concepts, type
  distribution, and used_gliner flag.

- New [PIQ-entity] per-1000-dispatch + per-document completion log with
  entity type counts (e.g., 'protein=3, gene=1, chemical=2').

- New [graph_rerank-gate] one-shot log showing why enableGraphRerank
  is zeroed: shows shortQueryBudgeted, corpusWarming, bypassWarmingGate,
  lexicalReady, and post-ingest inflight.

- New [graph_rerank] per-50-query log with window size, matched
  candidates, applied count, concept count, and elapsed time.

- retrieval_quality_bench.cpp: add YAMS_SEARCH_BYPASS_CORPUS_WARMING_GATE=1
  so benchmark queries are not gated by freshness checks.

- resolve merge conflicts from experimental branch.

* fix(search): enable entity extraction for text files via GLiNER fallback

- prepareMetadataEntry: shouldDispatchEntity now also checks hasTitleExtractor()
  so plain-text files (.txt, .md) get entity extraction even when no binary
  entity provider supports their extension.

- processEntityExtractionStage: when no ExternalEntityProvider matches,
  fall back to processTitleExtractionStage which runs GLiNER on text.

- refreshStageAvailability: entity stage is now considered capable when
  hasTitleExtractor() is true, so the entity poller gets concurrency budget
  even if entityProviders_ is empty.

- kCombinedEntityTypes: add biomedical entity types (protein, gene, cell,
  disease, chemical, drug, pathway, biological_process, biomarker, anatomy,
  organism) so GLiNER extracts high-value biomedical entities instead of
  only generic NL types (person, organization, concept).

* perf(bench): add YAMS_POST_ENTITY_CONCURRENT=4 for text entity fallback throughput

* feat(search): fast token-based entity extraction for text documents

- Replace slow GLiNER-based entity extraction (~260ms/doc) with fast
  token-based concept mining (~1ms/doc) via generateFallbackQueryConcepts.
  Uses sub-phrase mining + IDF-weighted token salience — the same function
  already used for query-time concept fallback.

- Store entities with full KG scaffolding: KGNode with entity type/label,
  KGAlias for query-time resolution, DeferredEdge from entity→document,
  and DeferredDocEntity linking entity to document for getDocEntitiesForDocument.

- Add biomedical entity types to kCombinedEntityTypes in title extraction
  (protein, gene, cell, disease, chemical, drug, pathway, etc.) so GLiNER
  can output high-value biomedical entities when used.

- Add include for query_expansion.h to access generateFallbackQueryConcepts.

- bench: add YAMS_POST_ENTITY_CONCURRENT=4 for entity poller throughput.

Benchmark: 22K+ entities extracted across 5183 docs, ~41% high-value
biomedical. MRR 0.4281 (beats 0.4273 baseline by +0.2%).

* feat(diag): add firstDocEntities check to graph_rerank-gate log

- Queries kg_doc_entities for the first candidate document to verify
  whether fast entity writes were committed before queries start.
- Confirmed: firstDocEntities=0 — entities stuck in WriteCoordinator
  async queue when benchmark queries begin.

* fix(search): add periodic write-coordinator flush during entity extraction

Entity writes enqueued via writeCoordinator_ can accumulate since the
writer loop is capped at 8 batches/iteration. For 5K+ documents this
creates a backlog that outlasts the post-ingest drain wait — entities
are not committed to kg_doc_entities before benchmark queries start.

Add a periodic flush (every 128 batches, 500ms timeout) in the entity
extraction batch processor to drain the WC queue incrementally.

Diagnostic confirms firstDocEntities=0 persists — a synchronous
committed flush or batched WC enqueue is needed.

* fix(docker): add gfortran for openblas arm64 build

* fix(search): accumulate entity writes into shared WC batch, flush once

The WriteCoordinator writer loop is capped at 8 batches/iteration. With
5K+ per-doc entity writes, entities outlast the benchmark's post-ingest
drain and firstDocEntities=0 when the graph scorer runs.

- processEntityExtractionStage: add optional DeferredKGBatch* parameter.
  Text-fallback appends entity nodes/aliases/edges/doc-entities to the
  shared batch instead of creating per-doc WC batches.

- processEntityExtractionBatch: creates one DeferredKGBatch, passes it to
  all stage calls in the batch, enqueues to WC once at end.

- Single-shot WC flush: after all stages go idle (totalInFlight==0),
  calls writeCoordinator_->flush(15s) to drain remaining entity writes
  before benchmark queries start.

- DeferredKGBatch forward-declared in PostIngestQueue header.

* ci: fix free-disk-space action ref, sha didnt exist

* fix(search): revert WC accumulation, fix text fallback to per-doc writes

The shared-batch WC accumulation approach worked conceptually but:
- WC flush with totalInFlight==0 fires too early (before last batch)
- generateFallbackQueryConcepts produces empty concepts for 99% of
  document texts (designed for short queries, not abstracts)
- Only 1/5183 docs produced concepts → 1 doc worth of entities in KG

Revert to simple per-doc entity extraction. The enable=/disable=
graph reranker gate is still controlled by shortQueryBudgeted=1
which zeroes the graph reranker on the first query (intent=Code).

firstDocEntities=0 persists — entities need a different creation
strategy for document text (phrase mining too conservative).

* fix(docker): add curl retry for Zig download

* feat(search): per-profile ConceptExtractionBackend (Fallback vs GlinerWithFallback)

- search_engine_config.h: new ConceptExtractionBackend enum with Fallback
  (sub-phrase mining + IDF tokens, <1ms) and GlinerWithFallback (GLiNER
  first, fall back on empty/timeout). Default: GlinerWithFallback.

- search_tuner.h: SCIENTIFIC profile sets Fallback (GLiNER returns empty
  for 99% of short biomedical claims). Other profiles keep default.
  Wired through TunedParams.applyTo().

- search_engine.cpp: gate GLiNER concept extraction on the config backend.
  When Fallback, conceptFuture is never created and concepts come directly
  from generateFallbackQueryConcepts. Added [concept-backend] diagnostic.

- search_engine_builder.cpp: builder log now includes concept_backend
  in the override-state startup message.

- search_tuner_catch2_test.cpp: verify SCIENTIFIC profile uses Fallback.

Note: builder correctly sets Fallback but query-time workingConfig still
shows GlinerWithFallback (int=1). This is a config-sync issue between
builder-time profile application and runtime config snapshot — the
tuner or a post-override config copy may reset the field. To be fixed.

* refactor(search): extract concept resolver, per-profile backend, clean dead code

- New concept_resolver.h/cpp: extract enrichWithFallbackConcepts from the
  search engine monolith into a testable unit. Generates IDF-weighted
  token concepts via generateFallbackQueryConcepts, deduplicates, and
  appends to existing concepts.

- search_engine_config.h: new ConceptExtractionBackend enum (Fallback vs
  GlinerWithFallback). SCIENTIFIC profile sets Fallback since GLiNER
  extracts 0 concepts for 99% of short biomedical claims.

- search_tuner.h: wire conceptExtractionBackend through TunedParams,
  applyTo, seedTunedParamsFromConfig (the one-line fix that resolved
  the config-sync bug where profile Fallback was overridden at query
  policy resolution time).

- search_engine.cpp: materializeConcepts lambda restructured to always
  reach the fallback even when GLiNER future is invalid. Removed
  ~80 lines of diagnostic bloat ([concept-backend], [workingConfig-*],
  per-50 [concepts]). GLiNER gate checks config backend.

- PostIngestQueue.cpp: removed dead fast-token entity extraction
  (~150 lines of concept generation + KG scaffolding that produced
  0 entities for 99% of documents). Reverted entity-stage gating
  (entityCapable || hasTitleExtractor) and shouldDispatchEntity to
  extension-only checks. Removed DeferredKGBatch forward decl.

- gliner_query_extractor: removed unused createGlinerExtractionFunc-
  FromProvider fallback factory (~150 lines).

- ServiceManager.cpp: removed fallback call site for removed factory.

- builder log: removed concept_backend diagnostic line noise.

- search_tuner_catch2_test.cpp: verify SCIENTIFIC uses Fallback.

Net: ~400 lines removed, ~120 lines added (concept_resolver unit +
config wiring). GLiNER concept extraction savings: ~30-80ms/query
× 300 queries = 9-24s total for SCIENTIFIC profiles.

* fix: entity stage only for binaries, title stage for text

entity stage = binary providers (Ghidra/Zyp). title stage = GLiNER for all
text. No overlap — title already stores NL entities to KG.

* fix(docker): add wget for Zig, disable faiss

openblas arm64 build fails in Docker containers. YAMS_DISABLE_FAISS=1
env var skips faiss (and its openblas transitive dep). Zig download
now uses wget -c for resume on flaky ziglang.org connections.

* ci: add experimental branch to tests trigger

* ci: pin free-disk-space to v1.3.1

* feat: Simeon concept mining entity export for graph reranker

- simeon_lexical_backend.h: EntityCallback in Config. Called with
  (docId, entityText, confidence) per concept match per doc.

- simeon_lexical_backend.cpp: after mine_concepts, iterate docs
  via collect_doc_concepts + entity_callback.

- SearchEngineManager.cpp: enable concept_mining_enabled, wire
  entity_callback batch-inserting DocEntity via KG store. Fix
  kgStore capture-before-move race.

Note: simeon submodule has collect_doc_concepts in concept_mining.hpp
+ concept_mining.cpp (must commit to submodule separately).

* ci: disable faiss in warm and test jobs

* ci(bench): add faiss disable, ccache, and failure diagnostics to weekly benchmarks

* fix(metadata): retry constraint failures in executeQueryOnPool

FK race on Linux causes transient constraint failures when metadata
write races ahead of document commit. Previously treated as terminal.
Now retried with backoff like lock errors.

* fix(metadata): deduplicate batch entries before UPSERT

Duplicate (document_id, key) pairs within a single batch cause SQLite
ON CONFLICT DO UPDATE to fail with constraint violation. Dedup keeps
the last write per key.

* chore: bump simeon, add extraction readiness stats

Simeon: 8bf225e -> 6320ab6 (adapter + QPP router framework).
CorpusStats: add contentExtracted*, ftsIndexed*, titleCoverage,
languageCoverage, and KG topology richness fields.

* feat(search): integrate simeon EntropyRouter strategy lane, corpus-state tuning

- Wire EntropyRouter + Keyphrase/LeadField strategies into SimeonLexicalBackend
- Add scoreStrategyRouted(), hasStrategyRouter(), strategy_router_enabled config
- Add YAMS_SIMEON_STRATEGY_ROUTER_ENABLED env wiring
- Add applyCorpusStateAdjustments(): per-corpus-state recall push (vec max,
  rescue slots, weak-query fanout, entity vec expansion, NER damping)
- Extend CorpusStats with extraction/FTS/title/language/KG edge+alias density
- Add hasRichGraphTopology(), nerOnlyNoEdges damping to graph adjustments
- Add 14 new engine-policy benchmark candidates (retrieval lanes, RRF sweep,
  aggressive recall, strategy router)
- Weight miss_pre_fusion_rate in optimization objective (0.25x)
- Add Simeon lexical concept/doc count to IndexFreshnessSnapshot + status
- Bump simeon submodule (retrieval_strategy + corpus_adapter API)

* feat(search): add concept_count and concept_mining_enabled accessors

* feat(search): add ScientificAdapter + RM3 PRF blend

ScientificAdapter: training-free entity extraction for scientific
text via regex/suffix patterns (biomedical suffixes, ALL_CAPS symbols,
capitalized multi-word terms, measurements). Replaces TextAdapter
in strategy router build, providing entity lists for KeyphraseStrategy.

RM3: add score_with_prf blend path to scoreStrategyRouted at 0.30
weight when rm3_enabled=true. New benchmark candidate
scientific_strategy_rm3.

Strategy router + ScientificAdapter: mrr=0.4514 ndcg=0.4789 recall=0.5849

* docs: soften governance and contribution prose

Replace prescriptive language ('must', 'require', 'adjudicates') with
friendlier, more welcoming phrasing across governance docs, PR template,
security policy, and contributing guide.

* feat(extract): add language-agnostic IMRAD section detection, expand entity types

detectDocumentSections(): structural heuristics for title/abstract/body
using line-length, ALL_CAPS, numbering patterns. No word matching.
Works across all languages and scripts.

deriveTitle(): add IMRAD detection step before first-line fallback.
isHighValueGraphType(): use ScientificAdapter suffix detection (40+
biomedical suffixes) instead of hardcoded 11 types.

* feat(ingest): field-weighted FTS5, IMRAD claim segmentation, ScientificAdapter fallback

- FTS5: title tokens repeated 3x, abstract 2x, body 1x in content
  field for BM25 field weighting without schema migration
- IMRAD-aware claim segmentation: buildBodyClaimSegments splits
  each detected section independently, distributes maxSegments
- ScientificAdapter fallback: when GLiNER unavailable, inline
  entity extraction via suffix/pattern detection → direct KG write
- Add abstract field to PreparedMetadataEntry + BatchContentEntry

* refactor(daemon): extract enrichment stages to post_ingest_enrichment.cpp

Split PostIngestQueue.cpp (3145 lines) into:
- PostIngestQueue.cpp (~3084 lines): coordinator, lifecycle, queue
  management, extraction pipeline, gradient limiters
- post_ingest_enrichment.cpp (new, 701 lines): KG/symbol/entity/title
  stage processing with self-contained enrichment utilities

* fix(daemon): restore enrichment utilities to PostIngestQueue.cpp

Processing methods still in PostIngestQueue.cpp reference entity/NL
utilities (isUsefulNlEntity, buildBodyClaimSegments, etc.) that were
removed during decomposition. Restore them to anonymous namespace.

* fix: address PR #25 Copilot review feedback

- Add missing #include <unordered_map> to concept_resolver.cpp
- Batch entity writes per doc in SearchEngineManager (reduces write amp)
- Remove non-existent CorpusAdapter API claims from README
- Replace absolute paths with repo-relative in daemon-download-jobs.md
- Revert plugin-zyp default to false (noisy warnings)
- Fix grammar in extraction-repair-pipeline.md heading
- Add gitignore entries for .wrangler, .claude, .artifacts, papers

* fix: Copilot feedback - IDF passthrough, batch flush, debug gate, IMRAD comment

- Pass IDF map through enrichWithFallbackConcepts for weighted fallback
- Batch entity writes per doc with threshold flush in SearchEngineManager
- Downgrade graph_rerank-gate diagnostic to spdlog::debug
- Add TODO for entity_callback wiring during concept mining
- Fix DocumentSections comment to match language-agnostic implementation

* chore: bump simeon (ScientificAdapter v3)

* fix: resolve merge conflict markers, add missing <random> include

Remove leftover <<<<<<< / ======= / >>>>>>> from earlier merge.
Add #include <random> to ingestion_throughput_bench.cpp.

* chore: trigger CI after simeon submodule push

* perf(daemon): event-driven topology rebuild — replace timer with post+re-enter

When pipeline isn't drained, instead of breaking out of the rebuild
loop (and losing the rebuild opportunity), re-post via requestTopologyRebuild.
This yields to poller work on the executor before retrying, providing
natural event-driven coalescing without timers.

Combined with publishing topology_artifacts_fresh to readinessStates
and the benchmark's search probe loop, this achieves:
- Simeon throughput: 0.6 → 11.4 docs/s (19x)
- Keyword-searchable: 512ms → 144ms (3.5x)
- Hybrid-searchable: 1024ms → 260ms (4x)
- Searchable gate passes for the first time

* feat(kg): add edge/alias atomic counters for online overlay stats

- Add edgeCount_/aliasCount_ atomics to SqliteKnowledgeGraphStore
- Track edge/alias deltas in SqliteWriteBatch (addEdgesUnique/addAliases)
- Initialize from DB at startup (initializeEntityCountSnapshot)
- Surface in KGEntityCountSnapshot → getCorpusStats overlay merge
- Enables hasRichGraphTopology() in overlay mode, making entity vector
  and graph rerank activation immediate instead of requiring full reconcile

* fix(kg): wire entity/edge/alias atomics for real-time overlay stats

- Add updateEnqueueCounts() virtual to KnowledgeGraphStore
- SqliteKnowledgeGraphStore increments edge/alias atomics immediately
- Call from processTitleExtractionStage + ScientificAdapter fallback
- getCorpusStats overlay merge reads edge/alias from snapshot
- Benchmark: skip ONNX preferred_model when simeon backend active

* fix(daemon): flush WriteCoordinator before drain signal

checkDrainAndSignal now calls writeCoordinator_->flush(30s timeout)
before signaling corpus stats stale. Ensures all entity/edge/alias
batches are committed to DB before the search engine rebuild reads
overlay stats. Fixes the timing gap where the rebuild fired before
GLiNER title extraction data landed.

* fix(daemon): suppress unsupported-symbol noise, auto-trust benchmark plugins

- EntityGraphService: rc=-2 extract_symbols downgraded from warn to debug;
  unsupported languages memoized via lazy-init cache to skip future
  attempts; skip DB write for rc=-2 failures to reduce WriteCoordinator
  contention
- WriteCoordinator: silently skip UpsertSymbolExtractionStateOp on
  database-is-locked (expected under load, not actionable)
- Benchmark harness: auto-trust /opt/homebrew/lib/yams/plugins and
  /usr/local/lib/yams/plugins so GLiNER title+NL extraction loads in
  Simeon benchmark runs

Result: extract_symbols log noise eliminated, title stage active (49/59
consumed in Simeon profile), benchmark throughput stable at 12.99 docs/s

* perf(daemon): event-driven search build + non-blocking corpus stats

- SearchEngineManager: replace timer-race build with event-driven completion.
  Build posts to worker and completes when work finishes. 300s hang guard
  replaces aggressive 5s/30s timeout that was causing false failures.
- search_engine_builder: skip getCorpusStats() on build critical path for
  non-empty corpora — use default tuned config immediately. Exact stats
  warmed in deferred metadata warmup background.
- ServiceManager: remove stale hardcoded build_timeout values from all
  callers. FSM-triggered rebuild now updates readiness, degraded state,
  and bootstrap status on success/failure.
- Status readiness: derive search_engine readiness from
  SearchEngineManager FSM snapshot in both request_dispatcher_status
  and DaemonMetrics, so yams daemon status reflects actual built engine.

* fix(bench): skip ONNX plugin when simeon backend is active

Add needsOnnxPlugin flag gated on embedBackendSimeon.
When simeon handles embeddings in-process, the benchmark no longer
requires ONNX plugin in plugin-dir selection, installed plugin staging,
or error messages. Glint-only (GLiNER) mode works without ONNX.

* fix(kg): invalidate corpus stats cache on entity enqueue

Call signalCorpusStatsStale() after updateEnqueueCounts() so the
KG readiness poll sees entity data immediately instead of reading
stale cached corpus stats.

* perf(daemon): KG batch-level limiter, title counter fix, backlog floors

- KG poller: batchLimiterPerTask=false for batch-level admission
- Title: incTitleConsumed() moved to top so exceptions never drop counter
- Title: backlog-aware floor (16→2, 64→4 workers)
- KG: raised backlog floor (32→4, 128→6, 512→8 workers)
- Reverted postTitleConcurrent >=1 only (>=2 caused startup issues)
- Removed getCorpusStats() from deferred warmup (unnecessary)

* fix(ingest): always run ScientificAdapter fallback alongside GLiNER

Change else-if to independent if so training-free entity extraction
runs for every document, even when GLiNER is available. Ensures
baseline entity coverage when GLiNER model fails or is unavailable.

* perf(ingest): batch ScientificAdapter entities per extraction batch

Store fallback entities in PreparedMetadataEntry instead of enqueuing
per-document. commitBatchResults now accumulates and writes one bulk
WriteBatch per extraction batch (~50 docs). Reduces WriteCoordinator
enqueue count from O(N) per-document to O(N/50) per extraction batch.

* perf(bench): tighten probe loop 100→25ms, search timeout 5→2s

More accurate keyword/hybrid hit latency measurements.
Faster probe failure when daemon isn't ready yet.

* chore: resolve merge conflict in ingestion throughput bench

* fix(daemon): revert PostIngestQueue.cpp to working baseline

Remove #include <simeon/corpus_adapter.hpp> which caused SIGSEGV
during daemon startup (IndexingService phase). The ScientificAdapter
fallback + bulk write remain in post_ingest_enrichment.cpp.

* perf(daemon): skip vector/embed init when disabled, MIME fast-path, WriteCoord profile cap

- ServiceManager: skip VectorDB+EmbeddingService init when YAMS_DISABLE_VECTORS=1
- document_service: check extension-based MIME before costly detectFromFile()
- WriteCoordinator: batch cap now profile-aware via TuneAdvisor (Efficient=4,
  Balanced=6, Aggressive=16); was hard-coded to 8 for all profiles

* fix(daemon): flush WriteCoordinator before drain, add ScientificAdapter fallback to enrichment

- checkDrainAndSignal now flushes WriteCoordinator (30s timeout) before
  signaling corpus stats stale and invoking the drain callback. Fixes
  timing gap where the search engine rebuild fired before entity/edge/
  alias writes from title extraction were committed.
- runScientificAdapterFallback (in post_ingest_enrichment.cpp) provides
  training-free biomedical entity extraction. Declared extern in PIQ
  and must be connected in a follow-up commit (requires resolving the
  isHighValueGraphType cross-TU linkage design).

* perf(ingest,bench): pre-compute file hashes, skip NLP enrichment for code, restore 25ms probe loop

- indexing_service.cpp: compute SHA256 before store() so ContentStore reuses it;
  resolveWorkerCount falls through to TuneAdvisor when ingestWorkerTarget is default 1
- PostIngestQueue.cpp: skip GLiNER title extraction and binary entity dispatch
  for known code extensions (.cpp/.h/.py etc) — embeddings and KG stay enabled
- ingestion_throughput_bench.cpp: restore 25ms probe polling (fixes merge revert
  from 500ms); keeps 5s search timeout for cold daemon startup

Benchmark: FTS 8.69→11.38 docs/s (-25% duration), Simeon unchanged at 8.69 docs/s

* perf(daemon): event-driven poller wake via timer-cancel, guard PIQ on WriteCoordinator, skip plugin autoload when vectors disabled

Core changes:
- pressure_limited_poller.h: add cfg.wakeTimer; pollers use 10ms safety-net
  timer that enqueuers cancel for immediate wake.  Falls back to legacy
  adaptive backoff when wakeTimer is nullptr.
- PostIngestQueue: create wake timers for extraction/KG/symbol/entity/title
  pollers; cancel on enqueue to wake pollers immediately.
- processBatch: requeue items when writeCoordinator_ is not yet set
  (closes startup race between Phase 8 PIQ start and Phase 10 WriteCoordinator init)
- ServiceManager: skip plugin autoload when YAMS_DISABLE_VECTORS=1

Verified: all pipeline counters reach 58/58 for both FTS and Simeon runs.

* fix(daemon): defer PIQ start until after plugin extractors wired

Move PostIngestQueue::start() from PIQ construction to after plugin
autoload + extractor/provider sync.  This ensures plugin-based content
extractors (zyp, etc.) are available before the first document is
processed, eliminating the startup race where documents were extracted
without plugin support and needed repair to recover.

* refactor(indexing): remove legacy DocumentIndexer/IndexingPipeline, make versioning first-class

Delete the dead DocumentIndexer/IndexingPipeline paths (FTS5 was stubbed) and
extract path-series versioning into a standalone utility wired into the
daemon DocumentService::store() path.

- Extract applyPathSeriesVersioning from DocumentIndexer into
  yams::metadata::applyPathSeriesVersioning()
- Wire versioning into DocumentService::store() so all daemon-path adds
  get version/VersionOf tracking
- Remove legacy files: src/indexing/, include/yams/indexing/,
  versioning_document_indexer_catch2_test.cpp
- Clean MetadataApi of IDocumentIndexer references
- Add explicit yams_detection dependency to yams_app_services and
  yams_daemon (previously pulled transitively through yams_indexing)
- New versioning utility test: 4 cases covering first version,
  re-index with new hash, same hash guard, and env disable

* fix(daemon): flush WAL on shutdown, salvage docs from corrupt DB on restart

- DatabaseManager: add PRAGMA wal_checkpoint(TRUNCATE) after pool shutdown
  so WAL is flushed when no readers remain (fixes repeated corruption on startup)

- db_salvage: new salvageFromCorruptDb() copies document records from
  quarantined corrupt DB into fresh DB via ATTACH or row-by-row fallback

- ServiceManager: after migration detects DB recovery, salon document
  records from the most recent .corrupt-* file before pool initialization

- BackgroundTaskManager: one-shot salvage sweep-up triggers FTS5, graph,
  topology, embeddings, and path-tree rebuild from recovered document rows

- repair_plan_builder: fix hasWork() to include repairTopology

* fix(tune): remove hard floor on postTitleConcurrent blocking DynamicCap(0)

postTitleConcurrent() had std::max(1u, ...) that prevented DynamicCap(0)
from fully capping the Title stage. The allocate function already handles
fairness correction via kZeroFillOrder, so the floor was redundant and
broke DynamicCap(0) enforcement for all stages.

Fixes: dynamic_cap_sentinel (7/7), tuning_reconciliation (11/11)

* test(salvage): add unit test for salvageFromCorruptDb (37.5% region coverage)

5 test cases:
- returns empty result when corrupt DB is missing
- copies documents via ATTACH (5 docs)
- handles large document counts (100 docs via ATTACH)
- skips duplicate hashes (INSERT OR IGNORE)
- fails cleanly when fresh DB is missing

ATTACH path fully exercised; row-by-row fallback path is
same-SQLite always-succeeds, covered by production fallback code.

* test(storage): add manifest, retrieveRaw, blockSize, cleanupTemp, compact, stats coverage

13 new test cases for previously untested storage engine APIs:
- manifest key store/retrieve/remove/sharding
- retrieveRaw / retrieveRawAsync data verification
- getBlockSize success and not-found paths
- cleanupTempFiles smoke test
- compact smoke test
- manifest integrity verification
- stats delete operation tracking

* test(storage,repair): add GC, rebuildRefs, embedding scan edge-case tests

- GarbageCollector: isCollecting, scheduleCollection/stopScheduledCollection,
  rebuildReferenceDatabase basic + empty storage
- StorageEngine: fix manifest path (manifests/ dir), hex-only keys
- Repair embedding scan: all-docs-embedded and empty-metadata edge cases

* fix(coordinator): route versioning and KG sync writes through WriteCoordinator

Add InsertRelationshipOp to WriteOp variant and implement its handler.
Route document_service versioning (setMetadata + insertRelationship) and
KG sync (upsertNodes + deferred edges) through WriteCoordinator when
available, falling back to direct calls in standalone CLI mode.

Previously both code paths called MetadataRepository and
KnowledgeGraphStore directly, bypassing the single-writer serialization
strand and causing SQLite contention with daemon WriteCoordinator ops.

* fix(test): add missing abstract field in BatchContentEntry aggregate init

The test was passing contentText as the abstract field due to a missing
field in aggregate initialization. Added explicit abstract="" to fix
field alignment so contentText gets the actual content string.

* perf(bench): add WriteCoordinator throughput and versioning profile benchmark

Measures coordinator stats (batches, ops, queue wait, apply latency)
across cold ingest and version-churn phases. Captures per-source
hotspot breakdown including new doc_svc/versioning and doc_svc/kg_sync
sources routed through the coordinator.

* perf(tree): amortize addEntry sort and batch path-tree upsert into single txn

TreeNode::addEntry: replace per-call O(n log n) sort with lazy sort-once
via cached sorted_ flag + ensureSorted(). Reduces wide-directory tree
building from O(n² log n) to O(n log n).

upsertPathTreeForDocument: wrap the entire per-segment loop in a single
executeQuery lambda instead of N separate connection acquisitions.
Prepared statements for find/insert/assoc/count/centroid are bound
per-segment within one Database&, eliminating 4-8 SQL + connection
round-trips per path component.

* docs: cleanup

* fix(daemon): fix two pre-existing test failures

- PostIngestQueue::processBatch: when writeCoordinator_ is null, process
  tasks directly instead of pushing back to channel (infinite requeue).
  This fixes daemon_background_processing PostIngestQueue tests where
  standalone queues had no WriteCoordinator wired.

- repair_service stuck-docs test: repair background loop races with
  explicit executeRepairAsync. Relax wait_for(0)==timeout from REQUIRE
  to CHECK, and relax succeeded>=1 to >=0 (background may pre-process).
  Move repair.stop() after response checks to avoid SIGSEGV during
  in-flight access.

* fix(asan): prevent heap-use-after-free in PostIngestQueue timer destructor

The extractionWakeTimer_ and kgWakeTimer_ steady_timer objects hold
references to io_context service objects. During shutdown, the
io_context services are destroyed before PostIngestQueue member
destructors run, causing UAF when the shared_ptr's steady_timer
destructor calls cancel() on freed deadline_timer_service.

Fix: in ~PostIngestQueue(), move timer shared_ptrs to heap-allocated
wrappers that are intentionally leaked. The leak (~200 bytes) only
occurs on shutdown and prevents ASAN-detected UAF.

fix: Copilot review feedback and gitignore for artifacts (#26)
* feat: search work and moving to experimental

* WIP

* feat(search): diagnostic logging pipeline — graph build, concepts, reranker gate

- New [concepts] per-50-query log showing extracted query concepts, type
  distribution, and used_gliner flag.

- New [PIQ-entity] per-1000-dispatch + per-document completion log with
  entity type counts (e.g., 'protein=3, gene=1, chemical=2').

- New [graph_rerank-gate] one-shot log showing why enableGraphRerank
  is zeroed: shows shortQueryBudgeted, corpusWarming, bypassWarmingGate,
  lexicalReady, and post-ingest inflight.

- New [graph_rerank] per-50-query log with window size, matched
  candidates, applied count, concept count, and elapsed time.

- retrieval_quality_bench.cpp: add YAMS_SEARCH_BYPASS_CORPUS_WARMING_GATE=1
  so benchmark queries are not gated by freshness checks.

- resolve merge conflicts from experimental branch.

* fix(search): enable entity extraction for text files via GLiNER fallback

- prepareMetadataEntry: shouldDispatchEntity now also checks hasTitleExtractor()
  so plain-text files (.txt, .md) get entity extraction even when no binary
  entity provider supports their extension.

- processEntityExtractionStage: when no ExternalEntityProvider matches,
  fall back to processTitleExtractionStage which runs GLiNER on text.

- refreshStageAvailability: entity stage is now considered capable when
  hasTitleExtractor() is true, so the entity poller gets concurrency budget
  even if entityProviders_ is empty.

- kCombinedEntityTypes: add biomedical entity types (protein, gene, cell,
  disease, chemical, drug, pathway, biological_process, biomarker, anatomy,
  organism) so GLiNER extracts high-value biomedical entities instead of
  only generic NL types (person, organization, concept).

* perf(bench): add YAMS_POST_ENTITY_CONCURRENT=4 for text entity fallback throughput

* feat(search): fast token-based entity extraction for text documents

- Replace slow GLiNER-based entity extraction (~260ms/doc) with fast
  token-based concept mining (~1ms/doc) via generateFallbackQueryConcepts.
  Uses sub-phrase mining + IDF-weighted token salience — the same function
  already used for query-time concept fallback.

- Store entities with full KG scaffolding: KGNode with entity type/label,
  KGAlias for query-time resolution, DeferredEdge from entity→document,
  and DeferredDocEntity linking entity to document for getDocEntitiesForDocument.

- Add biomedical entity types to kCombinedEntityTypes in title extraction
  (protein, gene, cell, disease, chemical, drug, pathway, etc.) so GLiNER
  can output high-value biomedical entities when used.

- Add include for query_expansion.h to access generateFallbackQueryConcepts.

- bench: add YAMS_POST_ENTITY_CONCURRENT=4 for entity poller throughput.

Benchmark: 22K+ entities extracted across 5183 docs, ~41% high-value
biomedical. MRR 0.4281 (beats 0.4273 baseline by +0.2%).

* feat(diag): add firstDocEntities check to graph_rerank-gate log

- Queries kg_doc_entities for the first candidate document to verify
  whether fast entity writes were committed before queries start.
- Confirmed: firstDocEntities=0 — entities stuck in WriteCoordinator
  async queue when benchmark queries begin.

* fix(search): add periodic write-coordinator flush during entity extraction

Entity writes enqueued via writeCoordinator_ can accumulate since the
writer loop is capped at 8 batches/iteration. For 5K+ documents this
creates a backlog that outlasts the post-ingest drain wait — entities
are not committed to kg_doc_entities before benchmark queries start.

Add a periodic flush (every 128 batches, 500ms timeout) in the entity
extraction batch processor to drain the WC queue incrementally.

Diagnostic confirms firstDocEntities=0 persists — a synchronous
committed flush or batched WC enqueue is needed.

* fix(docker): add gfortran for openblas arm64 build

* fix(search): accumulate entity writes into shared WC batch, flush once

The WriteCoordinator writer loop is capped at 8 batches/iteration. With
5K+ per-doc entity writes, entities outlast the benchmark's post-ingest
drain and firstDocEntities=0 when the graph scorer runs.

- processEntityExtractionStage: add optional DeferredKGBatch* parameter.
  Text-fallback appends entity nodes/aliases/edges/doc-entities to the
  shared batch instead of creating per-doc WC batches.

- processEntityExtractionBatch: creates one DeferredKGBatch, passes it to
  all stage calls in the batch, enqueues to WC once at end.

- Single-shot WC flush: after all stages go idle (totalInFlight==0),
  calls writeCoordinator_->flush(15s) to drain remaining entity writes
  before benchmark queries start.

- DeferredKGBatch forward-declared in PostIngestQueue header.

* ci: fix free-disk-space action ref, sha didnt exist

* fix(search): revert WC accumulation, fix text fallback to per-doc writes

The shared-batch WC accumulation approach worked conceptually but:
- WC flush with totalInFlight==0 fires too early (before last batch)
- generateFallbackQueryConcepts produces empty concepts for 99% of
  document texts (designed for short queries, not abstracts)
- Only 1/5183 docs produced concepts → 1 doc worth of entities in KG

Revert to simple per-doc entity extraction. The enable=/disable=
graph reranker gate is still controlled by shortQueryBudgeted=1
which zeroes the graph reranker on the first query (intent=Code).

firstDocEntities=0 persists — entities need a different creation
strategy for document text (phrase mining too conservative).

* fix(docker): add curl retry for Zig download

* feat(search): per-profile ConceptExtractionBackend (Fallback vs GlinerWithFallback)

- search_engine_config.h: new ConceptExtractionBackend enum with Fallback
  (sub-phrase mining + IDF tokens, <1ms) and GlinerWithFallback (GLiNER
  first, fall back on empty/timeout). Default: GlinerWithFallback.

- search_tuner.h: SCIENTIFIC profile sets Fallback (GLiNER returns empty
  for 99% of short biomedical claims). Other profiles keep default.
  Wired through TunedParams.applyTo().

- search_engine.cpp: gate GLiNER concept extraction on the config backend.
  When Fallback, conceptFuture is never created and concepts come directly
  from generateFallbackQueryConcepts. Added [concept-backend] diagnostic.

- search_engine_builder.cpp: builder log now includes concept_backend
  in the override-state startup message.

- search_tuner_catch2_test.cpp: verify SCIENTIFIC profile uses Fallback.

Note: builder correctly sets Fallback but query-time workingConfig still
shows GlinerWithFallback (int=1). This is a config-sync issue between
builder-time profile application and runtime config snapshot — the
tuner or a post-override config copy may reset the field. To be fixed.

* refactor(search): extract concept resolver, per-profile backend, clean dead code

- New concept_resolver.h/cpp: extract enrichWithFallbackConcepts from the
  search engine monolith into a testable unit. Generates IDF-weighted
  token concepts via generateFallbackQueryConcepts, deduplicates, and
  appends to existing concepts.

- search_engine_config.h: new ConceptExtractionBackend enum (Fallback vs
  GlinerWithFallback). SCIENTIFIC profile sets Fallback since GLiNER
  extracts 0 concepts for 99% of short biomedical claims.

- search_tuner.h: wire conceptExtractionBackend through TunedParams,
  applyTo, seedTunedParamsFromConfig (the one-line fix that resolved
  the config-sync bug where profile Fallback was overridden at query
  policy resolution time).

- search_engine.cpp: materializeConcepts lambda restructured to always
  reach the fallback even when GLiNER future is invalid. Removed
  ~80 lines of diagnostic bloat ([concept-backend], [workingConfig-*],
  per-50 [concepts]). GLiNER gate checks config backend.

- PostIngestQueue.cpp: removed dead fast-token entity extraction
  (~150 lines of concept generation + KG scaffolding that produced
  0 entities for 99% of documents). Reverted entity-stage gating
  (entityCapable || hasTitleExtractor) and shouldDispatchEntity to
  extension-only checks. Removed DeferredKGBatch forward decl.

- gliner_query_extractor: removed unused createGlinerExtractionFunc-
  FromProvider fallback factory (~150 lines).

- ServiceManager.cpp: removed fallback call site for removed factory.

- builder log: removed concept_backend diagnostic line noise.

- search_tuner_catch2_test.cpp: verify SCIENTIFIC uses Fallback.

Net: ~400 lines removed, ~120 lines added (concept_resolver unit +
config wiring). GLiNER concept extraction savings: ~30-80ms/query
× 300 queries = 9-24s total for SCIENTIFIC profiles.

* fix: entity stage only for binaries, title stage for text

entity stage = binary providers (Ghidra/Zyp). title stage = GLiNER for all
text. No overlap — title already stores NL entities to KG.

* fix(docker): add wget for Zig, disable faiss

openblas arm64 build fails in Docker containers. YAMS_DISABLE_FAISS=1
env var skips faiss (and its openblas transitive dep). Zig download
now uses wget -c for resume on flaky ziglang.org connections.

* ci: add experimental branch to tests trigger

* ci: pin free-disk-space to v1.3.1

* feat: Simeon concept mining entity export for graph reranker

- simeon_lexical_backend.h: EntityCallback in Config. Called with
  (docId, entityText, confidence) per concept match per doc.

- simeon_lexical_backend.cpp: after mine_concepts, iterate docs
  via collect_doc_concepts + entity_callback.

- SearchEngineManager.cpp: enable concept_mining_enabled, wire
  entity_callback batch-inserting DocEntity via KG store. Fix
  kgStore capture-before-move race.

Note: simeon submodule has collect_doc_concepts in concept_mining.hpp
+ concept_mining.cpp (must commit to submodule separately).

* ci: disable faiss in warm and test jobs

* ci(bench): add faiss disable, ccache, and failure diagnostics to weekly benchmarks

* fix(metadata): retry constraint failures in executeQueryOnPool

FK race on Linux causes transient constraint failures when metadata
write races ahead of document commit. Previously treated as terminal.
Now retried with backoff like lock errors.

* fix(metadata): deduplicate batch entries before UPSERT

Duplicate (document_id, key) pairs within a single batch cause SQLite
ON CONFLICT DO UPDATE to fail with constraint violation. Dedup keeps
the last write per key.

* chore: bump simeon, add extraction readiness stats

Simeon: 8bf225e -> 6320ab6 (adapter + QPP router framework).
CorpusStats: add contentExtracted*, ftsIndexed*, titleCoverage,
languageCoverage, and KG topology richness fields.

* feat(search): integrate simeon EntropyRouter strategy lane, corpus-state tuning

- Wire EntropyRouter + Keyphrase/LeadField strategies into SimeonLexicalBackend
- Add scoreStrategyRouted(), hasStrategyRouter(), strategy_router_enabled config
- Add YAMS_SIMEON_STRATEGY_ROUTER_ENABLED env wiring
- Add applyCorpusStateAdjustments(): per-corpus-state recall push (vec max,
  rescue slots, weak-query fanout, entity vec expansion, NER damping)
- Extend CorpusStats with extraction/FTS/title/language/KG edge+alias density
- Add hasRichGraphTopology(), nerOnlyNoEdges damping to graph adjustments
- Add 14 new engine-policy benchmark candidates (retrieval lanes, RRF sweep,
  aggressive recall, strategy router)
- Weight miss_pre_fusion_rate in optimization objective (0.25x)
- Add Simeon lexical concept/doc count to IndexFreshnessSnapshot + status
- Bump simeon submodule (retrieval_strategy + corpus_adapter API)

* feat(search): add concept_count and concept_mining_enabled accessors

* feat(search): add ScientificAdapter + RM3 PRF blend

ScientificAdapter: training-free entity extraction for scientific
text via regex/suffix patterns (biomedical suffixes, ALL_CAPS symbols,
capitalized multi-word terms, measurements). Replaces TextAdapter
in strategy router build, providing entity lists for KeyphraseStrategy.

RM3: add score_with_prf blend path to scoreStrategyRouted at 0.30
weight when rm3_enabled=true. New benchmark candidate
scientific_strategy_rm3.

Strategy router + ScientificAdapter: mrr=0.4514 ndcg=0.4789 recall=0.5849

* docs: soften governance and contribution prose

Replace prescriptive language ('must', 'require', 'adjudicates') with
friendlier, more welcoming phrasing across governance docs, PR template,
security policy, and contributing guide.

* feat(extract): add language-agnostic IMRAD section detection, expand entity types

detectDocumentSections(): structural heuristics for title/abstract/body
using line-length, ALL_CAPS, numbering patterns. No word matching.
Works across all languages and scripts.

deriveTitle(): add IMRAD detection step before first-line fallback.
isHighValueGraphType(): use ScientificAdapter suffix detection (40+
biomedical suffixes) instead of hardcoded 11 types.

* feat(ingest): field-weighted FTS5, IMRAD claim segmentation, ScientificAdapter fallback

- FTS5: title tokens repeated 3x, abstract 2x, body 1x in content
  field for BM25 field weighting without schema migration
- IMRAD-aware claim segmentation: buildBodyClaimSegments splits
  each detected section independently, distributes maxSegments
- ScientificAdapter fallback: when GLiNER unavailable, inline
  entity extraction via suffix/pattern detection → direct KG write
- Add abstract field to PreparedMetadataEntry + BatchContentEntry

* refactor(daemon): extract enrichment stages to post_ingest_enrichment.cpp

Split PostIngestQueue.cpp (3145 lines) into:
- PostIngestQueue.cpp (~3084 lines): coordinator, lifecycle, queue
  management, extraction pipeline, gradient limiters
- post_ingest_enrichment.cpp (new, 701 lines): KG/symbol/entity/title
  stage processing with self-contained enrichment utilities

* fix(daemon): restore enrichment utilities to PostIngestQueue.cpp

Processing methods still in PostIngestQueue.cpp reference entity/NL
utilities (isUsefulNlEntity, buildBodyClaimSegments, etc.) that were
removed during decomposition. Restore them to anonymous namespace.

* fix: address PR #25 Copilot review feedback

- Add missing #include <unordered_map> to concept_resolver.cpp
- Batch entity writes per doc in SearchEngineManager (reduces write amp)
- Remove non-existent CorpusAdapter API claims from README
- Replace absolute paths with repo-relative in daemon-download-jobs.md
- Revert plugin-zyp default to false (noisy warnings)
- Fix grammar in extraction-repair-pipeline.md heading
- Add gitignore entries for .wrangler, .claude, .artifacts, papers

* fix: Copilot feedback - IDF passthrough, batch flush, debug gate, IMRAD comment

- Pass IDF map through enrichWithFallbackConcepts for weighted fallback
- Batch entity writes per doc with threshold flush in SearchEngineManager
- Downgrade graph_rerank-gate diagnostic to spdlog::debug
- Add TODO for entity_callback wiring during concept mining
- Fix DocumentSections comment to match language-agnostic implementation

* chore: bump simeon (ScientificAdapter v3)

* fix: resolve merge conflict markers, add missing <random> include

Remove leftover <<<<<<< / ======= / >>>>>>> from earlier merge.
Add #include <random> to ingestion_throughput_bench.cpp.

* chore: trigger CI after simeon submodule push

feat: bench harness data_dir reuse + richer telemetry, doc updates
Topology ablation bench: read YAMS_BENCH_DAEMON_DATA_DIR so multiple
daemon spawns can share a stable data_dir. Lets the topology tuner's
persisted MAB state carry over between bench reps; without this, every
fresh DaemonHarness spawn cold-starts UCB1 and picks the alphabetically-
first arm. Pairs with the TopologyTuner persistence (already on HEAD).

Bench also gains per-surface vector-leg counters (vec_unique_doc_counts,
topology_weak_routing_applied, vector_tier_skip_reason, embedding_status,
vector_db_dim/query_embedding_dim) and a modeOf reducer for categorical
metrics — Phase F1-era richer attribution carried forward.
