Class: IndexedDbArtifactCache

Defined in: src/prover/artifact-cache.ts:37

Caches an inner ArtifactSource's resolved sets in IndexedDB (browser). The first resolve for a shape fetches + stores; later resolves read from IndexedDB, so the multi-MB zkey isn't re-downloaded per proof.

Wrap the source you want cached — including a VerifiedArtifactSource, so only integrity-checked bytes are ever stored. Cache entries are keyed by (version, shape): bump version (e.g. the armada-circuits build id) whenever the artifacts change to invalidate stale entries, or call clear().
