Conversation
Describes the settlement program's instructions/accounts/types for IDL-driven tooling (e.g. Solscan), since this is a native/Pinocchio program rather than an Anchor program and has no generated IDL. Several spots can't be fully expressed in the IDL grammar and are documented inline via `docs` fields instead: BeginSettle's dynamically-shaped tail (order count/bumps/transfer counts/pull amounts, which have no Borsh-expressible layout), and order_pda's PDA seed (a sha256 hash of the whole intent argument, not a plain field/account reference). Draft: we don't yet have a cheap way to validate that this IDL is actually correct - e.g. that it can build parsable/successful transactions for each instruction, and successfully parse real account data. That validation is intended as fast-follow work. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Summary
programs/settlement/idl/cow_settlement.json) describing the settlement program's instructions/accounts/types, for IDL-driven tooling (e.g. Solscan). This program is native/Pinocchio, not Anchor, so there's no generated IDL to start from.docsfields instead:BeginSettle's dynamically-shaped tail (order count / bumps / transfer counts / pull amounts) has no Borsh-expressible layout (no length prefixes, and a trailing array whose length is the sum of an earlier array).order_pda's PDA seed issha256(intent_bytes)— a hash of the whole instruction argument, not a plain field/account reference the PDA-seed grammar can point at.create_buffer's account list is padded to a chosen maximum (15) of indexed(buffer_pda_i, mint_i)pairs, since the real instruction accepts an unbounded number of them via remaining accounts.Stacked on #64 (discriminators), which is itself stacked on #63 (little-endian encoding) — the IDL only makes sense once both land.
Draft — why
We don't yet have a cheap way to actually validate this IDL against the real program: e.g. that it can build parsable/successful transactions for every defined instruction, and successfully parse real account data pulled from a running program. That validation is planned as fast-follow work; marking this draft until we have it.
