208
MATCH(exact counts) 208 = 26 × 8 = 16 × 13. Lagado v40 has exactly 208 ATOM cells, with ranks 0–207 forming a complete reading order on the 16×16 grid; the rest are 42 RESERVE and 6 OPERANT. Eight passes of a–z, one per q.d colour, therefore fill it exactly. Applying last batch's pair cipher to each pass, the 13 even letters cancel and the 13 odd letters survive: 104 cells cancel, 104 survive, and the value is 356 per pass × 8 = 2848.
MATCH(found, and explained) Every cancelled cell lies in the LEFT hemisphere and every survivor in the RIGHT. That happens because the v40 rank order strictly alternates hemispheres (even ranks on the right, odd on the left), and the letter parity follows the rank parity because 26 is even. It is a property of how v40 was ordered, not a message.
MODELPlacing letter (rank mod 26) with colour pass ⌊rank/26⌋ is Dave's framework, not a decipherment. The 13×16 view folds the 208 ranks into 16 rows of 13, so rows alternate a–m and n–z.

Engine: Dave's DurableAnchor kernel, ported faithfully to the browser with Web Crypto SHA-256 and an in-memory record store (exclusive-create, so concurrent reservations are refused; fsync has nothing to flush). The ledger starts empty on each load. Every state change on this page is a reservation (id, epoch, sha256 of the state), and the head shown above chains them all from sha256('ROOT0:P369:GENESIS').
