No visual proof cases have been published for this package yet. The registry summary below describes what the compat layer implements.

Working

findProof over the requested rangeStart/rangeSize (defaulting to the challenge maxProofLength), the leading-zero-byte difficulty test, the counter/hashBase64/attempts/timeMs result shape, undefined when the range is exhausted, and cancel stopping the search at the next batch boundary

Missing (2)

the native multi-threaded solverso a high-difficulty challenge takes far longer on the JavaScript SubtleCrypto path and cancellation only takes effect between 256-counter batches instead of immediately
