The COW version-control surface (fork, branches, checkout, commit,
getHistory/streamHistory, asOfCommit, brain.versions) is gone, along with
its subsystems: src/versioning/, the COW object store (CommitLog,
CommitObject, RefManager, TreeObject), HistoricalStorageAdapter, and the
TypeAwareHNSWIndex path it kept alive. The Db API (now/transact/asOf/
with/persist/restore) is the one versioning model in 8.0.
Survivors and replacements:
- BlobStorage survives (the VFS stores file content through it), relocated
to src/storage/blobStorage.ts with binaryDataCodec.ts; its adapter
interface is now BlobStoreAdapter, slimmed to the consumed surface
(write/read/has/delete/getMetadata + MIME-aware compression policy).
- brain.migrate() backup branches are replaced by persist-before-migrate:
MigrateOptions.backupTo persists a hard-link snapshot of the current
generation before any transform runs; MigrationResult.backupPath reports
it, and brain.restore(path) brings it back wholesale.
- CLI: cow.ts (fork/branch/checkout/history/migrate) is replaced by
snapshot.ts — snapshot <path>, restore <path>, history (tx-log),
generation.
- New public read API: brain.transactionLog({limit}) exposes the reified
tx-log (generation/timestamp/meta, newest first) that backs the CLI
history command; TxLogEntry is exported.
Tests: superseded suites deleted; fork/commit blocks excised from shared
suites; BlobStorage tests relocated + reworked against the slimmed store;
migration tests now prove the backupTo snapshot/restore round trip; new
transactionLog coverage in db-mvcc.
