Development record

itd-177 review residue: spc-55 names tests in lifecycle_test.go that do not exist (the equivalents live in claims_test.go under other names) and claims the gate reports a deletion as a marker known to the record's history, which no code holds; the stamp-only --json emits an empty spec object while the intent carries a spec_id; the two fix commits moved their issue records to resolved without a Resolves trailer (legal, but the trailer is the convention when the fixing change is the resolving one).
