- brain.fillSubtypes(rules): idempotent subtype back-fill for pre-8.0 data.
One rule per NounType/VerbType (literal default or per-entry function);
fills only entries still missing a subtype through the public update()/
updateRelation() paths; returns { scanned, filled, skipped, errors, byType }.
Full unit suite in tests/unit/brainy/fill-subtypes.test.ts.
- Fix getNouns/getVerbs pagination hasMore (peek one past the window) —
was permanently false, silently truncating every multi-page walk.
- find({ near }) without near.id now throws a teaching error instead of an
opaque storage sharding failure; CLI --threshold without --near applies a
plain score floor.
- CLI init/close audit: every one-shot command init()s, close()s, and exits
explicitly; delete the unmaintained interactive REPL; replace the cloud-era
storage subcommands with status/batch-delete; new types/validate commands.
- requireSubtype JSDoc now documents the 8.0 default-on contract; audit()
recommendation points at fillSubtypes.
- Docs: data-storage-architecture rewritten to the real 8.0 on-disk layout;
README storage section reflects filesystem+memory and snapshots; eli5 and
SEMANTIC_VFS /as-of/ semantics corrected; internal tracker IDs and
.strategy references scrubbed from published files.
The legacy backup/import/export/stats facade (src/api/DataAPI.ts) drifted
from the modern entity shape and every job it did now has a first-class
surface. Delete it and brain.data(), and rewire the CLI:
- data-stats → brain.stats() (full BrainyStats report: per-type breakdowns,
indexed fields, index health, storage backend, writer lock, version)
- clean → brain.clear()
- export → alias of snapshot; a db.persist() snapshot is the full-fidelity
export format (open with Brainy.load, load wholesale with brainy restore);
external data ingestion remains brainy import (UniversalImportAPI)
Rewiring clean onto brain.clear() exposed two real bugs, both fixed:
- clear() left this.graphIndex undefined forever — any graph-touching call
afterwards (relate, getNeighbors, stats) crashed. clear() now re-resolves
the graph index exactly as init() does and re-wires the shared UUID↔int
resolver, and re-resolves the metadata index with the same provider
fallback as init().
- storage.clear() reset the legacy totals but not the per-type/subtype
count rollups or id→type caches, so stats() reported phantom counts for
deleted entities. Both adapters now delegate derived-state reset to
reloadDerivedState(), the same path restore-from-snapshot uses.
One-shot CLI commands (data-stats, clean, snapshot/export, restore,
history, generation) now close the brain and exit explicitly — global
cache timers otherwise keep the process alive holding the writer lock.
Verified: build clean, 1383/1383 unit tests, 24/24 db-mvcc integration,
plus an end-to-end CLI smoke (add → data-stats → export → clean →
data-stats).
The __words__ keyword index stores 50-5000 entries per entity (one per
word), which inflated avg entries/entity well above the corruption
threshold of 100. This caused:
1. validateConsistency() to falsely detect corruption on every startup,
triggering unnecessary clearAllIndexData() + rebuild() cycles
2. getStats() to log false "Metadata index may be corrupted" warnings
and report inflated totalEntries/totalIds stats
Both methods now skip __words__ when counting, so stats and health
checks reflect metadata fields only (noun, type, createdAt, etc.).
Keyword search is unaffected since the __words__ field index itself
is not modified.
