Fields

build: BuildIdentity

process: ProcessIdentity

note_search_ann_route_total: u64

Process-lifetime note-search vector route counts, independent of this report’s database file and reset only with the serving process.

note_search_fallback_route_total: u64

search_mechanism: SearchMechanismSnapshot

Pool-scoped, monotonic coordinator dispatch and note-candidate hydration counts used by ADR-166 G4/G5. Reset on pool reconstruction.

db_path: Option<String>

None for an in-memory backend — the file-backed sections then carry their own unavailability reasons.

wal_ceiling: WalCeilingDiagnostics

Explicit WAL ceiling policy for this already-open database.

disk_guard: DiskGuardDiagnostics

wal_file: Option<WalFileState>

checkpoint_counters: CheckpointCounters

checkpoint_probe: Option<CheckpointProbe>

checkpoint_probe_error: Option<String>

checkpoint_pin: CheckpointPinDiagnostics

Frame pin fields serialized beside checkpoint_probe at the report root.

reader_contention: ReaderContentionDiagnostics

Reader route, checkout saturation, and hold-lifecycle signals.

writer_contention: WriterContentionDiagnostics

Writer-pool and best-effort audit persistence signals.

size_composition: Option<DatabaseSizeComposition>

size_composition_error: Option<String>

graph_edge_integrity: Option<GraphEdgeIntegrity>

graph_edge_integrity_error: Option<String>

fts_segments: Option<FtsSegmentDiagnostics>

Current FTS5 segment structure, decoded from each index’s documented one-row structure record (shadow-table row id 10). This does not scan either corpus or %_idx table.

fts_segments_error: Option<String>

fts_maintenance: FtsMaintenanceCounters

Process-lifetime outcomes from the checkpoint task’s bounded FTS5 maintenance steps.

wal_pin: WalPinAttribution

collection_cost: CollectionCost

Per-section assembly cost for this report. See CollectionCost.
