docs(adr): ADR-0145 amended — the ui-only clock reads the fixed group's spec tags; D1 names the #18003 level-half amendment

Two clauses of the record, one note each, under ADR-0087's amendment spelling;
the status entry records the acceptance by PR #27251's merge. The decision
(one major after the retirement, never longer) is unchanged; nothing is
implemented.

 - the window binds in both directions: a tombstone that names a spec retirement ⛔ never leaves while the spec still
   carries that key's kit (the ui author would lose the remedy the spec still prints), and ⛔ never outlives it — except
   as D3 holds it: a named refusal D3 keeps outlives the kit by design (the `agedOutSpecKeyRefusal` twins are that case).

 - **Where R cannot be read** (no tag, no row, a history the reader cannot reach): the tombstone is not due. The batch
   reports it as undated, ⛔ never guesses a date — a wrong date removes a remedy early, which is option B by accident.
