R14 correction to cookbook 156 + checkpoint p7. I blamed gate_stage's arity pre-pass (F1)
for the 141/213 breakage. That was wrong: no arity journal from the session mentions
func_80146A6C (74/26/4 entries checked) and the arity undo reported success in every log.
The real cause was dedup_propagate --recover leaving an orphaned caller-extern reconcile
(now fixed + proven, commit:1521 / commit:1522). F1 remains real, unguarded, and part of the
remaining Stage-1 work -- it simply did not cause this incident.
Generalizable law added to 156: a tool that deliberately leaves an edit on disk pending an
outcome owes a LEDGER for it. 'Keep it if this succeeds' is half a transaction; the other
half is undoing it on every path that can later invalidate the success, exit paths included.
commit:1519's commit message keeps the wrong attribution (history not rewritten, corrected forward).
