nounCountsByType (read by stats().entitiesByType / counts.byTypeEnum) was
incremented in saveNoun_internal(), which runs on every noun write — including
the HNSW index re-saving a node whenever its neighbor links change. So per-type
counts grew with graph connectivity instead of entity count (an internal report
saw 8 documents read as 44). Moved the increment into saveNounMetadata_internal(),
gated on isNew + visibility, exactly parallel to the authoritative total; the
visibility-flip path adjusts it in lockstep too.
Tests: tests/unit/storage/stats-count-accuracy.test.ts (30 dense-type entities ->
exactly 30 across stats/counts/getNounCount) + de-theatricalized the >=2 assertion
in brainy-core.unit.test.ts to exact equality. Build green; 1455 unit green.
Part of the 8.0 readiness audit Phase 1; cold-reopen count rehydration is still WIP.
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).
Brainy 8.0 makes subtype required by default on every public write path
(`add`, `addMany`, `update`, `relate`, `relateMany`, `updateRelation`,
import). Per the locked C-1 contract, every entity and relation gets a
non-empty subtype string by the time the storage layer sees it.
OPT-OUT REMAINS FULLY SUPPORTED
The runtime flag is still consumer-controlled. Three opt-out paths
cover migration / legacy fixtures / typed escape:
- `new Brainy({ requireSubtype: false })` — last-resort: turn off the
contract entirely. Recommended only for migration windows or test
fixtures that legitimately can't supply a subtype.
- `new Brainy({ requireSubtype: { except: [NounType.Thing, ...] } })` —
per-type allowlist: strict everywhere except the listed types.
- `brain.requireSubtype(type, options)` — per-type registration with
optional vocabulary. Composes with the brain-wide flag.
Default is now `true`. Opt-out is explicit and documented; nothing
silently degrades.
TEST SWEEP
Bulk-applied `requireSubtype: false` to every `new Brainy({...})` call
site across 120 test files. Three sed patterns covered the shapes:
- `new Brainy({` → `new Brainy({ requireSubtype: false,`
- `new Brainy<T>({` → `new Brainy<T>({ requireSubtype: false,`
- `new Brainy()` → `new Brainy({ requireSubtype: false })`
tests/helpers/test-factory.ts → createTestConfig() defaults
`requireSubtype: false` so test files using the helper inherit the
opt-out without per-site edits.
The test sites that DO exercise subtype semantics (the
subtype-and-facets suite, the strict-mode-self-test suite, the verb-
subtype-and-enforcement suite, etc.) already pass real subtypes — they
were the 7.30.x acceptance tests for this contract. Those tests
continue to pass unchanged.
CHANGES
src/brainy.ts
- normalizeConfig() — `requireSubtype` default `false` → `true`.
Comment refreshed to document the three opt-out paths.
tests/* (120 files)
- Bulk-edited brain construction sites. No functional test changes; the
opt-out preserves the test author's original intent.
tests/helpers/test-factory.ts
- createTestConfig() base config gains `requireSubtype: false`.
NO-OP for consumers who were already passing subtype on every write.
For consumers who weren't, the upgrade path is one of the three opt-out
forms above. Migration recipe documented in 8.0 release notes (next
commit).
VERIFICATION
- npx tsc --noEmit: clean
- npm test: 1408 / 1409 (same pre-existing race-condition outstanding;
no other regressions from the flip)
- Store data opaquely in add() and update() instead of spreading object
properties into top-level metadata. data is for semantic search (HNSW),
metadata is for structured where-filter queries (MetadataIndex).
- Fix numeric range queries in MetadataIndex — use numeric-aware comparison
instead of lexicographic string comparison for normalized values.
- Add data field to RelateParams and Relation types for relationship content.
- Add where.type → where.noun alias in metadata-only find() path.
- Rewrite README: focused ~350 lines from 791, quick start first, feature
showcase with mini-snippets, organized doc links, no version callouts.
- Add DATA_MODEL.md and QUERY_OPERATORS.md reference docs.
- Remove 10 outdated/redundant doc files consolidated into API reference.
- Improve JSDoc on Entity, Relation, AddParams, FindParams, and core methods.
- Fix tests asserting data properties appear in metadata (data model violation).
- Deprecate verb.source/target in favor of from/to (public) and sourceId/targetId (storage).
BREAKING CHANGE: Remove hard delete option from deleteVerb() for consistent API
- Add complete metadata namespace architecture with O(1) soft delete performance
- Implement periodic cleanup system for old soft-deleted items
- Add restore methods for both nouns and verbs
- Require metadata contracts for all augmentations
- Eliminate namespace collisions with clean separation (_brainy, _augmentations, _audit)
- Optimize index performance using flattened dot-notation for O(1) lookups
- Add comprehensive augmentation safety system with type-safe access control
- Maintain full backward compatibility for existing data
- Add enterprise-grade cleanup with configurable age thresholds and batch processing
