 * An approval transaction landing is not the same as the approvals being on
 * the books — re-read the chain (retrying across RPC propagation lag, the same
 * 3×750ms shape as redeem's post-transaction reads) and believe ONLY what it
 * says. An empty read can never count as granted, so a truncated RPC response
 * cannot fake success. Throws if every read attempt fails; the caller decides
 * how to report "chain state unknown". `readFn` is injected so tests can pin
 * the retry/verdict logic without an RPC.
