Prepare the EXACT otto_prepare_swap pair (envelope + prepareInput) that buys one of the executable Coinbase B20 tokenized equities on Base with USDC, as a LI.FI route through the fenced diamond whose receiver is the signing account. The token comes from the registry row named by executableEquityId and is never an input; the caller's registryCommitment must equal the commitment recomputed over the current record. The WORST PERMISSIBLE FILL (amount over the route's own floor) is checked against the equity's own Chainlink total-return mark and refused when it exceeds the pinned tolerance, or when the feed is frozen (> 24 h). Returns the pair unchanged plus a preview; never signs or submits — submit the pair through otto_submit_under_delegation under the end user's per-swap cap. Every envelope from this server is valid for 300 seconds from construction (valid_until); a stale envelope is refused by the verifier — request a fresh one.
