* 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
* fix(storage): always verify compressed CRC
* 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(core): add assertions and harden daemon lifecycle
* fix(daemon): tighten shutdown lifecycle invariants
* fix(test): add PressureLimitedPoller capability-sleep shutdown test
* refactor(vector): harden backend contracts
Split the vector backend surface into narrower contracts and
move entity read paths to Result<> so callers can distinguish
backend errors from empty results.
Also fixes the TurboQuant lazy-init race, makes VectorDatabase
error state thread-safe, wires eager index preparation, and
adds regression plus memory-scaling benchmark coverage.
* fix(vector): address audit findings plus hardening
Fix the five confirmed bugs: coroutine lifetime hazard in
embedding_generator (await_with_timeout outliving captured state),
VectorSystemManager init retry latch poisoning, incremental HNSW
persistence race, vec0 registry key collisions, and simeon PMI
output_dim/config() drift.
Add invariant hardening: PostIngestQueue stage validation +
numChunks assertion, VectorSystemManager success postcondition,
VectorDatabase TurboQuant non-null assertions on all quantize/
dequantize paths, and sqlite_vec_backend Simeon PQ range and
divisibility preconditions.
Also adds regression coverage for init-retry and lock-busy paths
and a locked node snapshot helper for safe incremental HNSW
persistence.
* fix(test): add PressureLimitedPoller wake-timer shutdown tests
* chore(vector): resolve clang-tidy hygiene across queue, vdb, and sqlite-vec
Replace unprotected std::getenv calls with locked getenvCopy helpers,
add debug-level logging to previously-silent catch blocks in
PostIngestQueue, VectorDatabase, and SqliteVecBackend, wrap
PostIngestQueue timer-detach allocations in try-catch, and fix
unsigned-widening / optional-deref / unused-include hygiene.
Verified with LSP diagnostics and rebuilds of catch2_vector_submodule
and catch2_daemon_component_submodule.
* fix(daemon): harden PressureLimitedPoller inFlightCounter null check
* fix(daemon): harden PostIngestQueue wait_until deadline checks
* fix(daemon): clean up recovery sentinels regardless of salvage count
Previously the .recovered-* sentinel and .corrupt-* file cleanup
was gated on documentsSalvaged > 0, leaving quarantine
artifacts to accumulate on repeated crash/recovery cycles where
the corrupt DB had 0 salvageable docs.
Move cleanup outside the salvage-count guard so stale
quarantine artifacts are always removed after examination.
* feat(vec0): restore persisted ANN index on daemon restart
After vec0 rebuild, probe for vectors_<dim>_hnsw_meta shadow tables
and load a previously-persisted HNSW index. When found, the ANN
index is set directly on the vec0 table, skipping the O(n log n)
rebuild that was previously paid on every daemon restart.
Removes the stub restoreVec0AnnIndexIfPresentUnlocked() in favor
of inline restoration in rebuildVec0DimUnlocked(), which has
the vec0 table already created and ready for ann_index assignment.

* refactor(services): extract list hydration helpers
* refactor(daemon): extract metrics snapshot helpers
* refactor(daemon): extract metrics counter snapshot
* refactor(daemon): extract metrics resource snapshot
* feat(graph): add daemon-backed explore
Wire graph explore through daemon IPC, keep CLI rendering stable,
and fall back locally when daemon transport or protocol skew fails.
Also add graph context service/tests, improve graph follow-up hints,
and keep release builds working with the current JSON library.
* fix(services): prevent prune delete metadata orphans
* fix(cli): honor data-dir in graph explore
- bypass daemon explore when the CLI pins a data dir so\n temp fixtures do not resolve against a long-lived global DB\n- guard snippet truncation and ratio math to remove Fold-\n reported underflow and div-by-zero paths\n- clamp zero-based symbol lines before rendering graph\n context
* fix(daemon): make lifecycle stop completion safe
* fix(daemon): gate db-open startup against shutdown
* fix(metadata): serialize FTS indexed counter updates
* test(daemon): simulate vector lock contention cross-process
* test(daemon): isolate post-ingest identity batch
* style(daemon): normalize test include order
* refactor(graph): split cli graph helpers
Keep graph command paths smaller and easier to evolve.
Lock graph explore/topology contracts into focused presenter,
dispatcher, and support tests so follow-up refactors keep the
current IPC and hot-path behavior intact.
* fix(config): harden expand_tilde and fix Windows XDG state path doubling
- expand_tilde: handle bare ~ and ~/ explicitly to avoid std::out_of_range
on substr(2) for single-char input
- getXDGStateHome: on Windows, go up two levels from %LOCALAPPDATA%\yams\state
to %LOCALAPPDATA% so callers' xdg/yams append doesn't double the yams segment
* fix(static-analysis): add logging to empty catch blocks and fix nosemgrep syntax
* fix(static-analysis): strip trailing text from nosemgrep comments
* fix(doctor): add logging to daemon_check empty catch blocks
* fix(db_repair): add logging to empty catch blocks
* fix(chunking): add precondition checks for rabin polynomial and windowSize
* fix(safety): add null precondition checks for Fold proved null-deref sites
* fix(daemon): widen init-failure dispatch, add null/dbz preconditions
InitializationFailedEvent races with shutdown — async init
fails after teardown begins. Widen canDispatch to accept
Ready/ShuttingDown. Add static_assert on SnapshotRing N>0.
Add YAMS_PRECONDITION null guards on hex/stages/data/bytes.
