It no longer describes all of consensus on chain 2800: since 2026-08-14 every anchor block must carry a certificate of validator post-quantum seals under its hash (Falcon-512, with SLH-DSA as well since 2026-09-04), and since 2026-09-05 every QBFT consensus message must carry a valid Falcon-512 seal of its author.

Since block 13,014,000 anchor blocks (every 32nd block, on every one since block 13,889,296) also carry, under the block hash, a certificate of validator Falcon-512 seals, and since 2026-08-14 a node rejects an anchor block with fewer than three valid seals (f+1 of nine; eight or nine are carried in practice). That is a post-quantum checkpoint about every 16 seconds, not a per-block quorum: the claim published on 2026-08-15 that from block 14,050,000 no block finalizes without a post-quantum quorum was wrong (the per-block rule armed at that height is retired in the shipped code in favour of the anchor rules) and was withdrawn on 2026-08-19.
