# scratch-h3a1

Scratch probe page for `machinery/retry-replay-behavior`, `machinery/reconcile-observability`, `machinery/conditional-writes-beyond-basehash` and `machinery/index`. No live findings live here; the measurements are on the pages named above. Second-confirmation run of 2026-10-08 (session `mach-confirm-2026-10-08c`) used this page for the If-Match/If-None-Match, frontmatter-vs-JSON, GET-write-form and rate-limit arms. Markers from that run remain in history.
