~/.local/state/yams/sessions grows without bound: tool integrations
create a session per run (1,596 opencode-* and 109 mcp-grep-hot* files
out of 1,764 on one machine) and nothing ever removes them.
Add expireIdleSessions() next to the session store and run it from
RepairService's idle maintenance once a day, only while no client is
connected. A session file is deleted only when nobody has created,
opened, closed or modified it for [daemon.maintenance]
session_expiry_days (typed config, default 30, 0 disables), and it is
kept when it is:
- the current session,
- watching a directory that still exists,
- still tagged on documents (they stay reachable through `session
merge` / `discard`; without a metadata repository ownership is
unknown and nothing expires),
- not valid JSON (not ours to judge).
Tests build a store shaped like the audited one and check each rule,
plus the RepairService wiring against a real metadata repository and
that a connected client defers the scan.

vectors.db had no reclaim path at all. On a real install it had grown to
39.7 GB with 48% of its pages on the freelist (about 19 GB of dead
space), while yams.db already had a startup auto-VACUUM with a size,
free-page-ratio and free-disk check.
Move that decision into a shared sqlite_vacuum helper so both databases
follow the same rules, and let RepairService's background loop check
vectors.db once a day (15 minutes after start, typed config
[daemon.maintenance] vector_vacuum_interval_hours, 0 disables).
VACUUM holds the vectors.db write lock for the whole rewrite, so it only
starts while the daemon is idle: no client connections, resource
pressure below Warning, no queued or in-flight embedding writes, no
VectorIndexCoordinator rebuild or bulk load, and no on-demand repair.
It runs on its own connection with file-backed temp storage and a short
busy timeout, so a live writer makes it back off instead of waiting, and
a progress handler rolls it back as soon as any of those signals change
or shutdown starts. Readers on the owner's connection are unaffected in
WAL mode. Besides the data-dir free-space rule it also requires the temp
directory to hold a copy of the live pages.
Tests cover the thresholds (including the audited 39.7 GB / 48% case),
a real vacuum that shrinks a file, abort and live-writer back-off, the
admission truth table, and RepairService vacuuming a live VectorDatabase
file only when idle, which stays writable afterwards.

Migration 40 dropped the symbol tables and graph edges, but the daemon
could still adopt an external symbol_extractor_v1 plugin (for example a
0.19 plugin left in a user plugin directory) and rebuild them.
Remove the interface header, the ABI adapter, plugin adoption, the
EntityGraphService extract-and-write path, the post-ingest symbol
channel, the write-coordinator symbol ops, and the KG-store symbol
metadata and extraction-state API. The ABI loader and the external host
now refuse a plugin that declares the interface (or the legacy
symbol_extraction capability) with a one-time warning. Status no longer
reports symbol extractors, generated configs no longer write
[plugins.symbol_extraction] (an existing section still parses), and
the benchmark suite drops symbol_extraction_bench.
Tests that exercised the dropped tables or the v39 schema template are
removed; the rest run against the current schema.
BREAKING CHANGE: code-symbol extraction is gone. Removed: the
symbol_extractor_v1 plugin ABI, `yams config grammar` (list, download,
path, auto-enable, auto-disable), the grammar steps in `yams init`, the
meson option `plugin-symbols`, the conan option
`enable_symbol_extraction`, and the Windows installer SymbolPlugin
component. Databases migrate to schema 41; a v0.19 binary refuses to
open them, and symbol data dropped by migration 40 cannot be recovered.
Drop legacy Tree-sitter symbol extraction subsystem, associated database
tables, triggers, and AST edge types:
- Migration 40 drops symbol_metadata, document_symbol_extraction_state,
symbol_metadata_fts, associated triggers, and prunes historical bloated
topology snapshots while preserving active snapshot topology,
semantic_neighbor edges, and non-symbol observed_as provenance edges.
Exclude nl_entity:% nodes from kg_nodes / kg_edges pruning to preserve
canonicalized method-type technology entities.
Provides complete downSQL restoring symbol tables, indexes, FTS virtual table,
and sync triggers for clean v39 rollbacks.
- In EntityGraphService, ensure locally resolved documentDbId propagates to
WriteBatch for knowledgeGraphDocumentId to ensure accurate enrichment
token completion, and only populate batch->documentIdToDelete for snapshot
documents with a resolved document database ID.
- In SymbolEnricher and SearchService, restore one-directional symbol-contains-query
matching with non-empty checks to prevent short substrings matching broad queries.
- In tests/unit/metadata/symbol_metadata_schema_test.cpp, migrate test DB up to
version 39 so tests pass against their target version prior to v40 table drops.
- Remove Tree-sitter grammar download and compile workflows from CLI init
- Default plugin-symbols to false.
- Fix macOS daemon client and CLI executable resolution using
_NSGetExecutablePath with candidate fallbacks.
- Add migration validation tests and symbol enrichment unit tests.

* refactor(tuning): prune dormant runtime knobs
Remove unused tuning controls and adaptive search budget state. Extract testable ONNX slot reconciliation and search telemetry hydration seams, and correct the Apple Silicon sysctl value width.
* refactor(vector): retire dormant backends
Remove unused FAISS, model-infrastructure, VectorIndexManager, and TurboQuant paths while keeping Simeon PQ and float-vector storage.
Migrate unused V2.2 quantized schemas transactionally to V2.3. Databases containing non-default quantized formats or packed-code blobs fail closed with recovery guidance and no mutation.
* refactor(plugins): remove legacy SDK tooling
Remove the Ghidra and SDK submodules, their bespoke tests, and stale scan exclusions. Retain generic PluginProcess coverage against the repository mock fixture.
* build(vector): remove stale FAISS overrides
* refactor(ipc): remove dormant FSM snapshots
* refactor(ingest): unify bounded KG enqueue
* fix(plugins): harden allocation contracts
Keep ABI outputs null or fully initialized when allocations fail, and represent empty object payloads without relying on malloc(0).
* fix(storage): define empty object reads
Return a null buffer with zero length for successful empty-object reads instead of treating malloc(0) as an allocation contract.
* refactor(storage): trim through string views
* test: prune dormant harness helpers
Remove unused readiness and fixture helpers, and keep benchmark client-count doubling in a wide integer domain.
* chore(cpp): initialize analyzer-facing locals
* build(simeon): advance analyzer cleanup
* refactor(config): drop dead daemon client keys
* refactor(ipc): inject daemon client transport
Socket and in-process execution now share DaemonClient request dispatch, so CLI fallbacks do not need alternate service paths.
* refactor(retrieval): route CLI through daemon
Search and grep now use the same daemon handlers over socket or in-process transport. Live grep remains an explicit freshness inspection.
* refactor(graph): move CLI scope into daemon
Graph CLI requests now share daemon handlers across socket and in-process transports. CWD filtering occurs before pagination so scoped totals and pages stay correct.
* build: isolate test-only runtime controls
* refactor(metadata): decouple lock telemetry
* fix(services): return on request timeout
* fix(retrieval): enforce workspace scope
* fix(graph): scope nodes before pagination
* fix(grep): drop binary result lines
* fix(daemon): bound checkpoint wait
* fix(repair): use KG health checks

* perf(vector): skip unchanged PQ snapshots
* build(zyp): exclude bench from default build
* build: protect Meson files from formatter
* refactor: remove unreachable production APIs
* refactor(daemon): remove dormant runtime state
* fix(vector): harden daemon provider calls
Timed-out coroutines must own their client and requests. Provider discovery must also fail instead of returning synthetic embeddings in production.
* refactor(storage): remove unusable adapters
* fix(cli): unify in-process add requests
* fix(tsan): preserve async worker progress
* test(cli): isolate daemon-dependent suites
* fix(repair): expose queue backoff progress
* fix(release): repair package repo publish
Arch repo metadata and R2 uploads need to be reproducible from CI, with retry hardening for transient Cloudflare failures.
* fix(daemon): stop shutdown log storm
Init waiter must treat ShuttingDown as terminal so daemon shutdown tests do not flood Meson logs while the daemon is stopping.
* refactor(cli): delegate serve to MCP binary
Keep yams serve UX while removing MCP server linkage from yams-cli. The standalone MCP binary owns stdio serving and exits on stdin EOF.
* refactor(cli): move daemon path helpers
Keep CLI path resolution out of YamsDaemon so later link cuts can separate CLI and daemon internals. Full yams_daemon removal still needs a socket-only daemon-client split.
* refactor(daemon): split embedded client
* perf(search): add lean-guided benchmark gates
Add Lean topology/search models, ingestion ablation docs, and focused regression tests for topology and compression threshold behavior.
Extract search observability, keep benchmark-only ablation controls, and make retrieval quality benchmarks default to Simeon while preserving explicit ONNX opt-in.
* refactor(config): move daemon policies
* refactor(daemon): extract plugin runtime
* refactor(daemon): untangle service coordinators
Untangle CLI/MCP from daemon service coordinators and the daemon static lib.
- MetadataRepository uses a daemon-neutral tree-diff callback. The
GraphComponent wrapper moves to src/daemon/components/metadata_graph_bridge.cpp,
owned by the daemon library.
- WriteCoordinator moves to a dedicated build-only yams_write_coordinator
static lib. Drop ResourceGovernor coupling inside the writer loop; batch
sizing still respects config.maxBatchSize.
- AppContext gains enqueuePostIngest callback. ServiceManager wires it to
its own enqueuePostIngest; app services no longer call ServiceManager
directly.
- Embedding repair uses BulkIngestLease/BeginBulkIngestCallback instead of
concrete VectorIndexCoordinator::BulkScope. Daemon dispatchers provide a
lease factory backed by the real coordinator.
- CLI daemon_command uses config helpers instead of YamsDaemon::getXDGRuntimeDir.
- Remove explicit dependency('yams_daemon') from src/cli and tools/yams-mcp.
- Declare missing yams_extraction/yams_ingest deps on yams_app_services so
app services link cleanly without daemon.

* feat(bench): add xplan multi-arm experiment harness
Unified plan runner, ablation axes, REPORT/ablation docs, and
KPI snapshot so optimization loops stop living in shell matrices.
* feat(formal): expand topology/search Lean contracts
Boundary models for search provenance, construction gates,
and cluster/route objectives so Lean guides correctness while
xplan ranks performance levers.
* feat(search,topology): construction purity + graph expansion path
Raise topology build defaults (min edge 0.25, max component 64) and
split oversized CC pieces so hybrid assist is quality-positive on
scifact. Add GraphNeighbors expansion with medoid-anchor fallback,
structured helpers instead of nested session logic, and BEIR-default
xplan plans. Search engine extraction (fanout/classic pipeline) rides
along as the integration surface for routing.
* feat(topology): add KMeans engine and SGC identity contracts
Register kmeans in the factory with deterministic spherical k-means
over embeddings, and enforce SGC document-identity invariants in
debug builds with matching unit coverage.
* feat(daemon): topology readiness gates and selectable reranker
Drive topologyReady from published epoch/freshness/rebuild/dirty
ingest state (not just KG drain), surface those fields in search
stats, and wire onnx|simeon|auto|none cross-reranker selection.
* chore(search): drop meta_path tuner knobs
Meta-path routing is gone; remove dead TunedParams fields and the
ConfigResolver test for [search.meta_path].
* feat(bench): add topology_purity_validate plan
Repeats=3 validation matrix for construction-purity winners vs
topo_off so MRR deltas can clear run-to-run noise.
* chore: format add_command and config include order
Mechanical clang-format / include reorder only; no behavior change.
* feat(bench): decision-grade xplan loop for search engine
Document search-engine measurement in AGENTS; harden xplan with
repeats=3 plans, quality×latency primaries, mechanism metrics from
debug.jsonl, multi-rep log promotion, and archive superseded topology
plans.
* feat(graph): denser product semantic_neighbor topK
Raise default YAMS_GRAPH_SEMANTIC_TOPK fallback from 4 to 8 so product
graphs leave fewer degree-0 docs for GraphNeighbors expansion.
* feat(search): extract topology assist and cross-rerank seams
Pull topology assist into search_topology_stage (seed merge, skip
reasons, optional vector seed probe default 0). Extract cross_rerank
compute from search_engine. Wire probe via typed config/ConfigResolver.
* feat(bench): product-path search engine ablation plans
Add topology-off component, vector-weight, and tiered-execution xplan
plans (repeats=3) and wire them into the AGENTS measurement loop table.
* fix(ci): repair pre-push fallbacks
* feat(bench): lock-free mid-run builds + multi-corpus gates
xplan skips meson rebuild when the quality binary exists (flock +
YAMS_BENCH_FORCE_BUILD override) to stop multi-arm link races. Add
graph_vector weight and nfcorpus transfer-gate plans; document in AGENTS.
* fix(daemon): keep SearchEngine alive via shared_ptr cache
getCachedEngine previously published a raw pointer that metrics polling
used through rebuild, racing destructor of SearchEngine::Impl (TSAN).
Store and return a shared_ptr snapshot so diagnostic readers pin the
engine for the duration of getConfig/health checks.
Also adds the cautious vectorWeight 0.30→0.20 multi-corpus xplan plan.
* feat(search): route vectors through cached topology
Build and reuse validated topology snapshots, rank routed members by query similarity, and narrow the vector leg to the accepted document set with explicit work diagnostics.
Remove the retired HDBSCAN engine and vendor dependency, preserve typed topology policy through search tuning, and cover the runtime/configuration contracts.
* feat(bench): consolidate search decision plans
Enforce deterministic experiment identity and declared baselines, expose routed/global vector work metrics, and register the focused benchmark contracts.
Promote the compact repeats=3 routing-budget gate, archive superseded topology mechanism screens, and add multi-corpus product calibration plans.
* feat(search): refine topology vector routing
* fix(search): propagate daemon readiness
* feat(bench): measure generalized memory health
* fix(cli): honor in-process fallbacks
* ci: harden smolvm debug builds
* perf(search): route topology through filtered ANN
* feat(bench): measure read-write pressure
* perf(metadata): index symbol lookups on read pool
* fix(daemon): isolate startup reads and maintenance
* feat(bench): replay isolated generalized corpora
* feat(search): add evidence routing pipeline
Replace the blocking smolvm pre-push path with host ASan/TSan validation, harden sanitizer-sensitive smoke tests, and add recovery cleanup for malformed SQLite WAL sidecars.
* refactor(search): unify topology evidence path
Remove classic and sidecar fusion lanes so topology augments the recall-preserving ANN and lexical candidate pool through one product path.
* refactor(bench): prune superseded search lanes
Measure the topology-plus-ANN product path with stable experiment identity and remove obsolete sidecar and tiered controls.
* docs(search): retire stale experiment notes
Keep the benchmark handoff focused on the topology-plus-ANN product lane and its active decision plans.
* refactor(search): prune dead search surfaces
Remove unused fusion, reranker, policy, and router abstractions.
Bound topology materialization and keep document trace payloads opt-in.
* fix(cli): clear build warnings
* fix(xplan): reject stale run identity
* refactor(search)!: remove legacy query stack
Replace the unused AST/ranker/post-processor surface with focused facet aggregation used by product search.
BREAKING CHANGE: removes query parser, result ranker, search filter, and SearchResults container APIs from yams_search.
* refactor(search): type value stage traces
Remove synthetic ComponentResult markers for embedding and concept stages. Preserve failure and timeout states instead of overwriting them with fake successful results.
* refactor(search): isolate benchmark env overlays
Move test-only search environment parsing behind an injectable internal adapter. Keep all existing overlay keys and tuner pin semantics while restoring SearchEngineBuilder to composition.
* refactor(search): unify topology routing options
Snapshot topology policy once at the assist boundary and pass it through routing sessions and diagnostics. Remove repeated scalar copying without changing routing behavior or metric keys.
* fix(search): unify tuner config ownership
Use one complete config-to-params overlay for runtime seeding and no-tuner policy resolution. Reseed attached tuners on setConfig so reported and executed configuration cannot diverge.
* fix(search): snapshot tuner state per query
Read tuned config, params, and state under one lock before routing. Add a TSAN correlation test so adaptive observation cannot produce a torn logical query snapshot.
* fix(search): enforce topology routing contract
Generated configs must preserve hybrid-assist shadow routing, while daemon-backed search must abstain when published topology artifacts are stale. Keep standalone validation and global ANN recall intact.
* fix(daemon): let SQLite reclaim its file
Directly resizing a live database from sampled page counts can truncate pages allocated by concurrent writers. VACUUM must remain the only file-reclamation mechanism.
* fix(metadata): tolerate missing symbol FTS
Readiness lookups can race an unavailable optional FTS migration. Retain the indexed fast path, but retry against the base table when prepare or cached-statement execution proves the capability absent.
* build(fuzz): drop removed query parser target
The optional AFL build still referenced the deleted legacy query parser API and could no longer compile.
* fix(bench): include writes in drain oracle
A zero post-ingest queue is not durable drain while coordinated writes remain queued or in flight.
* fix(daemon): vacuum padded WAL databases safely
