The review of 2026-10-09: a digest over Go's JSON of a struct changes when a tag is renamed or a field
added, and another language cannot reproduce it. An act is now a flat map of named strings, and both
digests are over length-prefixed values in a fixed order, versioned; a test fails when a field is added
to Ask or Option without being added to the digest.
A warrant named the ask by id and the option by id, and the asker acted on whatever its record held
for them. Now the ask carries, for every option above acknowledge, the digest of exactly what it
performs (Option.Binds, ActDigest), the router puts the digest of the ask it took in the warrant
(Warrant.AskDigest), For refuses a warrant whose digest is not that of the ask the asker keeps, and
Option.Performs refuses an act the option did not bind. A warrant then authorises one act, as the
person was shown it, once.
