v0.22.0

Added

• The framework declares a deviations type. A deviation records a knowing departure from a policy or a standard:
  the clauses it departs from, the person who accepted the risk, the day they accepted it, and the day somebody looks
  at it again. departs-from names those clauses one by one and refuses a bare policy or standard id, because a bare
  id claims a departure from every clause the rule carries. kac update --add-type deviations takes it, and kac new
  offers it beside the rest. Three rules run over a record. review-after-acceptance errors where the review date falls
  on or before the acceptance date, so a deviation cannot expire as it is written. not-open-ended warns where the
  record reads as a standing departure rather than a bounded one. expiry warns where a record is still active on a
  day its review-by has gone by, and stays a warning so a late review never makes deleting the record the cheapest
  way to a green build.
• A rule expression can call today(). It answers with the day the run happens, as an ISO date, so a rule compares
  it against a date field under the string comparison the grammar already uses between two dates. The day is read once
  for the whole run, so a corpus validated across midnight cannot answer one way for its first record and another for
  its last.

Changed

• The template's shape is at version 7. It carries the deviations page, its index and its record template, so a
  corpus running kac update is offered the type.

Fixed

• A field may name a part spelled unlike the record holding it. id-format read the whole entry as one id, so
  std-ERRORS.a-failure-says-what-happened failed: a standard's record id carries a mnemonic and its rules are
  heading slugs. The check now reads the record and leaves the part to ref-resolves, which is what answers for
  whether the part exists.
