Module interchange 

Canonical serialization, content hashing, export and import.

The interchange format is a JSON Bundle: records with their full (or viewer-filtered) histories. Hashes are SHA-256 over the canonical JSON form: UTF-8, object keys sorted by code point, no insignificant whitespace, numbers and strings as produced by serde_json.

Imported bundles are untrusted: size limits, format/version checks, hash verification, origin policy, history replay and full validation are all applied before anything is written.

Structs

Bundle

BundleEntry

ImportPolicy

Rules for accepting a bundle from elsewhere.

ImportReport

Enums

Completeness

Whether a bundle carries complete histories or a viewer-filtered view.

Constants

BUNDLE_FORMAT

Functions

canonical_json

Serialize to canonical JSON bytes.

content_hash

SHA-256 of the canonical JSON form.

export

Export records (and their histories) as viewer may see them. Records the viewer cannot see are silently omitted.

import

Import a verified, complete bundle. Events already present (same event id at the same position) are skipped, so re-importing is idempotent and a newer export of the same records only appends what is new.

parse_bundle

Parse and verify an untrusted bundle without writing anything.
