AIP-22: the measured shape of chain 2800 'today' (Motivation) gave the certificate grid and threshold of before stages 1 and 2; corrected in place with today's values (Falcon-512 every 32nd block, hybrid every 128th, at least seven per scheme) and a dated note (2026-10-12)

## Motivation ## Motivation
Chain 2800 today has the following measured shape (sources in the Specification): every validator refuses a commit unless it carries a valid Falcon-512 seal bound to its author, and the nine validators that run the primary client refuse every QBFT message on the hot path (proposal, prepare, commit, round-change) without one, since block 17,700,000; the second client, which runs the tenth validator, refuses any commit without one since block 18,131,633, while its proposal, prepare and round-change layers take effect at stage 4 below (`H_fin`, whose height is not yet set on chain 2800); every 128th block carries a hybrid Falcon-512 + SLH-DSA-SHA2-128s certificate over its parent under the block hash, with at least six valid seals per scheme of the ten validators; and `aere_getPqFinality` returns, on every validator, the Falcon seals it heard for a recent block, re-verified (ten of ten on 2026-09-22). A validator that is online therefore finalizes nothing without post-quantum seals. (Corrected 2026-10-09: until that date this paragraph said that the four message types are refused without a seal "since block 17,700,000 on both clients"; on chain 2800 the second client enforces its commit layer only, and its other three layers take effect at stage 4. See the Errata entry of that date.)
