- AerePqFinalityTags: eth_getBlockByNumber("finalized"/"safe") answers the parent of the last canonical anchor that carries a
post-quantum certificate (v1 Falcon list or v2 scheme-tagged); monotonic, never moved back by a reorg. Fork choice, validity
and import are untouched.
- PqTipAdoptionGate / PropagatedBlockAdoptionGate: from the header-seal stage, a validator does not adopt a propagated block at
its own consensus tip without a post-quantum commit quorum for that exact hash, re-verified against the anchored registry.
Inert below that stage; readers and the sync path are not gated.
- ParallelSigning: SLH-DSA-SHA2-128s signing spreads the message-independent work (the hypertree layers' authentication paths
and the FORS trees) over the available cores; the output is byte-identical to Bouncy Castle 1.80 (SlhDsaParallelSigningTest
compares against the original for several keys and message lengths and counts the tasks that ran on the pool). Kill switch:
-Daere.pq.slhdsa.parallel=false. The engine files are regenerated from the pinned Bouncy Castle sources; the MIT licence stays
alongside them.
- Header-seal stage: a block re-proposed in a later round carries the seal of that round's proposer; the QBFT codec requires a
32-byte vanity field at every height. Comments translated to English throughout.
