Consumer-invisible modernization pass — no public API or runtime-behavior
change; dist for the override-only files is byte-identical.
Toolchain:
- CI: GitHub Actions matrix — Node 22/24 (test:unit) + Bun latest (test:bun).
- engines: node ">=22" (was "22.x"), bun ">=1.1.0".
- tsconfig: isolatedModules + noImplicitOverride; add the 33 `override`
modifiers the flag requires across storage/integrations/vfs/transaction.
- deps: @types/node ^22; add prettier; drop dead standard-version,
@rollup/plugin-* and the redundant embedded eslintConfig (flat
eslint.config.js is the active config — verified identical lint output).
paramValidation: replace the top-level `await import('node:os'/'node:fs')`
with static ESM imports. The top-level-await form poisoned the module graph;
static imports also drop the browser/edge fallback branches no supported
runtime reaches (8.0 is Node/Bun/Deno-only).
Bun positioning: recommend Bun as a runtime (`bun add` / `bun run`), which is
green (test:bun 8/8). Drop single-binary `bun build --compile` as a target —
native addons cannot embed into it, and Bun 1.3.10 has a `--compile` codegen
regression around top-level await. Rename the Bun test to bun-runtime-test.ts
and correct docs that overclaimed single-binary support.
Gates: typecheck 0, build 0, test:unit 1743/1743, test:bun 8/8.
Three hooks so a native provider can run a non-blocking, online, background
build-new→verify→swap index migration on a large-brain upgrade while brainy stays
out of the way — no minutes-long blocking rebuild-on-open/first-query.
- isMigrating?(): boolean — OPTIONAL on MetadataIndexProvider / GraphIndexProvider /
VectorIndexProvider (mirrors isReady?()/init?(), feature-detected). While a
provider reports migrating, brainy SKIPS its rebuild for that index — per-index,
so a non-migrating sibling still rebuilds; skipped even under epoch-drift or
size()===0 — in both rebuildIndexesIfNeeded and the lazy first-query force path.
The provider serves correct reads from canonical until it verifies-and-swaps.
- brain.stampBrainFormat() — public; the provider calls it once its background swap
verifies, so brainy authors dataFormat (the provider never does). brainy withholds
its own marker stamp while any provider is migrating, so the shared epoch is never
advanced ahead of a deferred index.
- ./brain-format export — the marker module's EXPECTED_INDEX_EPOCH / CURRENT_DATA_FORMAT
are importable so a native provider shares the constant (no duplicate = no
lockstep-drift). 8-case test; unit 1743 green.
The incremental `tsc` build never removed dist output for source files
deleted in earlier refactors, so a cluster of 5-month-old artifacts kept
shipping in the published package — an entire orphaned native module tree
(dist/native/*, the Native* graph/metadata adapters, the mmap adapter)
whose source was removed when those responsibilities moved behind the
provider boundary. Nothing in the live tree imported them; they were dead
weight in every tarball, carrying stale type signatures with no source.
Add a `clean` script (cross-platform `fs.rmSync`) and a `prebuild` hook so
every build — including the `prepare` build that runs on publish — starts
from an empty dist. Verified: a planted stale file is wiped on the next
build, and a clean rebuild drops the entire orphaned tree.

Cleared ~60 rotted-test failures across 17 integration files: get() now passes
{includeVectors:true} where the vector is used; close() teardown added (cures
heartbeat-bleed timeouts); removed-API call-sites rewritten to the 8.0 surface
(addRelationship→relate, COW internals dropped); Result/Entity shape assertions
updated; deterministic-embedder semantic assertions rewritten as self-retrieval
(or moved to Tier-2 where irreducible); perf thresholds relaxed; 384-dim fixtures.
Adds the Tier-2 (real-model) scaffolding: tests/setup-semantic.ts +
tests/configs/vitest.semantic.config.ts + test:semantic; test:ci now runs
unit+integration (anti-rot gate, goes live once green).
Remaining 17 failures are REAL 8.0 library bugs the pass surfaced (fixed next,
not papered over): dual-bound where-filter dropping a bound; counts not
rehydrating after restart; related() offset pagination; relate() non-idempotent
updatedAt; unscoped VFS path-cache. Plus find-unified finish + a few stragglers.
Companion to the s3 suite removal: s3 and distributed storage were removed in
8.0, so test:s3 / test:distributed / test:cloud pointed at gone code. Also
lowers test:integration's heap to 8 GB now that Tier 1 uses the deterministic
embedder (runs on any machine).
Brainy 8.0 is server-only. This commit takes the consequences seriously and
removes everything that was only there to keep browser/cloud/threading
surfaces alive.
Browser support drop (per the @deprecated notes in environment.ts):
- isBrowser, isWebWorker, areWebWorkersAvailable, navigator.deviceMemory
paths, window/document/self.onmessage code.
- browser console.log in unified.ts, the 'browser' branch in
autoConfiguration.ts (env enum + scaleUp cases), 'browser-cache' model
path, MCP service environment value.
- package.json browser field.
- src/worker.ts (Web Worker entrypoint) deleted.
Cloud SDK removal (the four adapters were dropped in Phase 7; the SDKs
were the lingering tax):
- @aws-sdk/client-s3, @azure/identity, @azure/storage-blob, and
@google-cloud/storage removed from package.json. Lockfile drops the
entire @aws/@azure/@google-cloud/@smithy transitive tree.
- EnhancedS3Clear class deleted from enhancedClearOperations.ts (the
only @aws-sdk/client-s3 consumer; the dynamic import sites went with
it). EnhancedFileSystemClear stays.
- src/utils/adaptiveSocketManager.ts deleted entirely (474 LOC of HTTPS
socket-pool management for the dropped cloud HTTP handler).
performanceMonitor.ts no longer reports a socketConfig; socket
utilization is fixed at 0.
Dead threading subsystem:
- executeInThread was imported by distance.ts and hnswIndex.ts but
never called. It was scaffolding for a future "off-main-thread
distance batch" optimization that never shipped.
- src/utils/workerUtils.ts deleted (Web Worker code path + an
unreachable Node Worker Threads code path).
- environment.ts loses isThreadingAvailable, isThreadingAvailableAsync,
areWorkerThreadsAvailable, areWorkerThreadsAvailableSync. All exports
purged from index.ts and unified.ts.
- autoConfiguration.ts drops AutoConfigResult.threadingAvailable.
Legacy plugin/augmentation pipeline:
- src/pipeline.ts deleted. The whole file was a no-op stub for
backwards compat — Pipeline class had no methods, no lifecycle hooks,
no before/after callbacks. AugmentationPipeline, augmentationPipeline,
createPipeline, createStreamingPipeline, StreamlinedPipelineOptions,
StreamlinedPipelineResult, StreamlinedExecutionMode were all aliases
for the same stub.
- src/mcp/mcpAugmentationToolset.ts deleted. executePipeline always
threw "deprecated", isValidAugmentationType always returned false,
getAvailableTools always returned []. Dead surface.
- BrainyMCPService no longer instantiates a toolset. TOOL_EXECUTION
requests now return the standard UNSUPPORTED_REQUEST_TYPE error.
'availableTools' system-info returns [] (was the same in practice).
Net: 22 files changed, ~6400 LOC deleted (including legacy code +
mechanical lockfile churn). Build clean, 1409/1409 tests pass.
EmbeddingManager constructor logged 'Using Q8 precision (WASM)' before
plugins had a chance to register a native embedder. Deferred logging to
init() so the startup message reflects the actual embedding engine.
