acceptance-protocol

Writes the protocol of a user acceptance round in docs/acceptance/: a checklist per test case (TC-XXX) from its Flow table and validations, and per use case that no test case covers from its scenario, alternative flows, and business rules, each row with columns for result, tester, date, and remark. Records the results a tester reports, then closes the round: every use case at Tested whose rows all passed and that no blocking question holds is proposed for Done, and set to Done after the user confirms. Use when the user asks to "prepare the acceptance test", "create the UAT checklist", "write the acceptance protocol", "record the acceptance results", "TC-002 step 4 failed", "close the acceptance round", "which use cases can go to Done", or mentions user acceptance testing, UAT, sign-off, or the Transition phase. It never changes a use case other than its Status line, and never sets a status without the user's word.
