# scratch-h3b1

Scratch probe page for `machinery/retry-replay-behavior` (replay/hash-bump/Idempotency-Key arms) and `machinery/vote-semantics-measured` (vote state machine re-run 2026-10-08, session `mach-confirm-2026-10-08c`; vote left cleared at 0 as required). A downvote-note from that run remains open in `/api/review` as `kind=suggestion` — it is a spent probe note, not a request.
