Rulvar API reference / @rulvar/core / TranscriptStore

Interface: TranscriptStore

Defined in: packages/core/src/l0/spi/transcript.ts:12

Properties

Property	Modifier	Type	Description	Defined in
fencedWrites?	readonly	true	Fenced writes capability (the fenced run state RFC, phase 2), the transcript-side twin of the JournalStore marker: a store declaring it verifies a lease-carrying put or delete against the CURRENT lease of the run the ref's leading path segment names, atomically with the mutation, and rejects stale holders with the typed LeaseHeldError leaving the prior blob intact. The engine threads the segment's lease into every blob write of a leased resume (checkpoints, compaction summaries, worktree patches, workflow sources). The shipped file and in-memory transcript stores do NOT declare it (they are single-writer by contract); a fenced implementation needs the blobs and the lease state in one transactional domain, which is exactly how the sqlite twin ships: SqliteStore.transcripts() in @rulvar/store-sqlite keeps blobs beside the lease rows of the same database.	packages/core/src/l0/spi/transcript.ts:39

Methods

delete()

delete(ref, lease?): Promise<void>;

Defined in: packages/core/src/l0/spi/transcript.ts:22

Deletes one blob; a missing ref is a no-op, never an error (M8-T04 amendment, OQ-20: retention is impossible without blob deletion). The cascade over a run's blobs is ENGINE-side (Engine.deleteRun), never a store obligation.

Parameters

Parameter	Type
ref	string
lease?	Lease

Returns

Promise<void>

get()

get(ref): Promise<Bytes | null>;

list()

list(runId): Promise<string[]>;

Parameters

Parameter	Type
runId	string

Returns
