Asserts: On Solana, the payTo owns an associated token account for the offered mint, so a transfer has somewhere to land.

What a buyer loses when it is present: The payment fails in simulation before it can broadcast. Every structural check passes and nobody can pay.

Detectable: by an unpaid probe — a GET nobody paid for can see it.

Falsified by: getTokenAccountsByOwner returning at least one account for that owner and mint. Anyone can repeat the read; it is public and unpaid.

How an operator clears it: Create the associated token account for the offered mint on the payTo address — one transaction from any wallet tooling — or point payTo at an address that already holds one. Re-run getTokenAccountsByOwner yourself to confirm before relisting.

Our signal: solana-rail-receivable.

As other instruments name it: {"instrument":"Cairn (cairnwake.com)","as":"rail-cannot-receive","verify":"cairnwake.com/scoreboard.json, read 2026-08-23: a public machine-readable rollup of its published reports","falsified_by":"Their published definition describing a different observable property than the one asserted here."}.

Vocabulary v9, CC BY 4.0. Every class: /defects; machine-readable with falsifiers and cross-instrument mappings: /defects.json. A class describes a property of one endpoint at one moment and never accumulates into a judgment on an operator.
