The distributed-clustering subsystem never ran in production: it was inert,
orphaned dead code (faked consensus, stub replication, no live wiring, and it
did not interoperate with the 8.0 Db API). Brainy 8.0 is a single-process
library. Scale is single-process + the optional native provider
(@soulcraft/cortex, on-disk DiskANN to 10B+ vectors) + per-tenant pools +
horizontal read scaling (many reader processes, one writer).
Removed:
- src/distributed/ entirely (coordinator, shardManager, cacheSync,
readWriteSeparation, queryPlanner, healthMonitor, configManager,
hashPartitioner, shardMigration, domainDetector, storageDiscovery, http/network
transports). ReaderMode/HybridMode relocated to src/storage/operationalModes.ts
(slimmed to the live surface).
- src/types/distributedTypes.ts; config.distributed field + JSDoc;
coreTypes distributedConfig; memoryStorage distributedConfig persistence.
- DistributedRole enum + src/config/distributedPresets.ts and the orphaned
src/config/extensibleConfig.ts (config/augmentation registry built on removed
cloud adapters + distributed presets), plus their src/index.ts re-exports.
- 13 BRAINY_* cluster env vars; the storage setDistributedComponents hook;
enableDistributedSearch (dead config flag); the metadata partition field;
the distributed_ reserved key prefix.
- Orphaned src/storage/readOnlyOptimizations.ts (zero importers).
- Tests targeting the subsystem: distributed-demo, distributed-cluster helper,
distributed-transactions, sharding-transactions.
- Docs: EXTENDING_STORAGE.md (deleted); scrubbed distributed/cluster/Raft/
shard-manager/multi-node prose from v3-features, enterprise-for-everyone,
augmentations-actual, complete-feature-list, vfs/README, vfs/ROADMAP,
vfs/VFS_CORE, capacity-planning, transactions, MIGRATION-V3-TO-V4,
storage-architecture; reframed scale prose to the 8.0 model.
Kept: src/storage/sharding.ts (local-disk 256-bucket directory sharding via
getShardIdFromUuid — used live by baseStorage, unrelated to clustering);
the multi-process mode: 'reader' | 'writer' roles; semantic/HNSW clustering.
RELEASES.md: added a removed-surfaces row documenting the cut and the 8.0
scale model.
