Yorke Rhodes	c5c217f8ea	feat: embed package version in deployed bytecode (#4518) ... ### Description Embed NPM package version in all deployed contracts bytecode. Follows [similar pattern to published CLI version](3010e36ec9/typescript/cli/src/version.ts (L0-L1)). Should not be conflated with `Mailbox.VERSION` used for message encoding. ### Drive-by Changes Unfixes solidity NPM package version from typescript packages ### Backward compatibility No, only applies to new deployments or upgrades ### Testing Tested [changeset glob](https://changesets-docs.vercel.app/fixed-packages#using-glob-expressions) ```ts console.log(micromatch(['@hyperlane-xyz/sdk', '@hyperlane-xyz/core', '@hyperlane-xyz/cli'], ['@hyperlane-xyz/!(core)|*'])); ['@hyperlane-xyz/sdk', '@hyperlane-xyz/cli'] ``` Added test that version function is on ABI	2 months ago
Yorke Rhodes	cb404cb85c	feat: implement checkpoint fraud proofs (#4277) ... ### Description Implements 4 categories of checkpoint fraud proofs for use in future validator slashing protocol: 1. **premature**: if a checkpoint index is greater than the corresponding mailbox count, it is fraudulent 2. **non local**: if a checkpoint origin does not match the checkpoint's mailbox domain, it is fraudulent 3. **message id**: if a checkpoint message ID differs from the actual message ID (verified by merkle proof) at the checkpoint index, it is fraudulent 4. **root**: if a checkpoint root differs from the actual root (verified by merkle proof + root reconstruction) at the checkpoint index, it is fraudulent Notably this is implemented independently from signature verification to allow for multiple checkpoint signing schemes to reuse the same checkpoint logic. ### Related issues - Touches https://github.com/hyperlane-xyz/hyperlane-monorepo/issues/3799 - See https://github.com/hyperlane-xyz/hyperlane-monorepo/pull/2431 for previous discussions ### Backward compatibility Yes ### Testing Unit testing with fixtures in `vectors/merkle.json` that are generated by the rust merkle tree and proof code	4 months ago
