…measured gas Insert the assembled 355-byte runtime bytecode and its per-fork keccak256 code hash into the canonical paymaster section, replace the ~2,150 gas estimate with the measured validation-path cost, and add the reference artifacts asset file.
Present the reference contract as annotated EVM assembly (mnemonics, labels, per-block comments) alongside the compiled bytecode and code hash, matching the house style of the system-contract EIPs. The listing assembles byte-for-byte to the pinned runtime bytecode and hash.
…prose Describe the validation-path cost structurally (dispatch, three SIGPARAM reads, memory-only APPROVE, one cold SLOAD) rather than quoting a fork-specific gas figure, since the deployment fork is undetermined. Tighten the assets pointer and reproducibility note.
Remove the superseded assets/eip-8141/CanonicalPaymaster.sol (old 12h-delay, secp256k1-only, arbitrary-recipient withdrawal design with no rotation), which the assembled canonical paymaster in this PR supersedes. Introduce 15,000 as the recommended pay-frame gas_limit bound rather than referencing it as if defined elsewhere. Correct the admin-path claim that both finalize paths clear pending state before acting (rotation writes slot 0 before clearing, and has no external call to observe ordering). Harmonize two remaining "code match" phrasings to the runtime-code-hash-of-the-active-fork wording. Reword the assets closing line to point at the annotated listing as the reproducible source instead of a non-checked-in assembler.

Completes the canonical paymaster implementation with its assembled reference runtime, code hash, and annotated assembly. Continues #12012.
