This reads any public repo’s own history in the browser — no server, every request visible in devtools.
One GitHub request per commit that touched a rule file; GitHub allows 60 an hour per visitor. A long history can spend that in a single read — the CLI has no such limit.

Prose instructions are not tracked. This port is simplified — the CLI reads full history, signs a receipt, and wins any disagreement.

the gateguard locks every dead rule and fails CI on an undeclared return, with the kill history in the failure. The specimen runs it on itself — three blocked pull requests and one declared restoration in its PR tab.
receiptsFindings carry a signed receipt that recomputes offline — three implementations on disjoint stacks. The verdict does not require trusting the party that produced it.
