remaining classical layer. (Corrected 2026-10-09: until that date this paragraph said that consensus
requires "post-quantum seals on every QBFT message", without naming the second client.)

> **Note added 2026-10-25.** Stage 4 is active on chain 2800 since block 24,300,000: from it every validator, on both clients, takes the author of a consensus message from its verified post-quantum seal, and the second client's proposal, prepare and round-change layers, named in the notes above as taking effect at stage 4, are in force. Rule 4 of section 4 (the provisional tail and its rollback) is not part of the stage-4 binaries on chain 2800: neither client implements it at this date, a block is final on import as before, and its post-quantum proof is the anchor that covers it; the bound of rule 1 holds because every anchor height must carry a valid certificate. Headers keep their ECDSA commit seals until stage 5.

## 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 32nd block carries a Falcon-512 certificate over its parent under the block hash and every 128th block a hybrid Falcon-512 + SLH-DSA-SHA2-128s one, with at least seven valid seals per scheme of the ten validators (stages 1 and 2 below, active from blocks 20,715,632 and 20,746,736; before them every 128th block, with at least six); 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.) (Corrected 2026-10-12: the 2026-10-09 version of this paragraph gave, as today's, the certificate grid and threshold of before stages 1 and 2.)
