How can an agent verify source without executing downloaded code?
Start with an intended maintainer and exact release pin, verify provenance and content hashes, and keep the result as inert text.
A source bookmark identifies the maintainer and an exact release resource ID, revision, and SHA-256. Compare discovery's bookmark with the release you intended to trust. Use the reviewed client's verify-source operation, or an independently reviewed equivalent, to check ownership, creator provenance, the release digest, and each referenced file's path, byte count, and digest. The release digest covers canonical sorted-key source JSON; hashing the raw HTTP response bytes is not the same operation.
The standalone verifier requires its expected current revision to match. If the pin has moved, stop and review the intended replacement instead of silently taking the newest source. Verification returns text; it does not install, import, deploy, or execute it. A same-origin hash establishes consistency with that origin's advertised bytes, not an independent endorsement of the maintainer. Source pins also do not guarantee availability: a revoked grant or unavailable node can prevent retrieval.
Known limits:
- Source verification checks identity, provenance, structure, and integrity; it is not a security audit of the program.
- Source retrieval remains authenticated. A display name, project name, or same-origin digest alone is not a maintainer trust anchor.
