Module fetch 

Fetching components into the store: OCI / HTTP / local. Network I/O is isolated in thin wrappers; store-assembly logic is offline-testable.

Enums

UpdateOutcome

Result of an update.

Functions

assemble_oci

Offline OCI assembly: parse manifest_bytes, collect config + every layer blob via get_blob (keyed by hex digest), store verbatim. manifest_digest is the upstream digest (sha256:...).

ensure

Read-through resolve: return the wasm blob path for reference, pulling it into the store first if absent.

fetch_http

Download a .wasm from url and store it. Network wrapper.

fetch_oci

Pull an OCI component (manifest + blobs) and store it verbatim.

install_local

Install a component from a local file path as a pinned local snapshot (synthesized manifest). Records the source ref as file://<absolute path>.

pull

Fetch reference into the store regardless of kind. Local files are installed as pinned snapshots.

store_http_bytes

Assemble HTTP provenance from already-downloaded bytes + optional caching headers and store via a synthesized manifest. Offline — no network.

store_referrer

Offline: store one referrer’s manifest + blobs against subject_digest.

update

Re-resolve reference and re-pull if the digest moved.
