Protocol system prefix carried by components sourced from the pAMM price level stream. The
venue suffix is either a configured name (e.g. pricelevelstream:fermiswap) or, for
auto-detected pAMMs, the venue address (e.g. pricelevelstream:0x5979…); every such protocol
maps to the generic PropAMMSwapEncoder.
Protocol system prefix for pAMM components executed through the PropAMMRouter, so a stale maker
quote retries on Uniswap V3 instead of reverting the route. Venue suffixes follow
PRICE_LEVEL_STREAM_PREFIX; only whitelisted venues may use it. Calldata matches the direct
path, so both prefixes share PropAMMSwapEncoder and differ only in the executor.
