org.cairnsproto.draft.getRecordProof

A commit proof of a project, policy, procedure or check record at one version, kept from when the indexer first saw that version: a CAR whose root is the signed commit, with the MST path to the record and the record. A PDS proves only a record's current version, and its author can rewrite or delete it, so this keeps every executable version open to inspection and lets a snapshot pinning a version the repo has since replaced, such as one still routed during an activation delay, be bundled. The indexer keeps every proof it fetches for good. A verifier checks the commit's signature, so the proof needs no trust in the indexer.
