Summary

Two changes to fix the testnet compatibility test breakage on v4-next:

1. Fix test to match actual testnet deployment

  • Testnet was deployed without SponsoredFPC — remove it from genesis computation
  • Update expected genesis archive root to 0x15684c8c... (verified against on-chain testnet L1 rollup at 0xf6d0...c1 on Sepolia)
  • All 3 values verified on-chain: VK tree root, protocol contracts hash, genesis archive root

2. Bust test cache when pinned artifacts change

  • Mix hashes of pinned-protocol-contracts.tar.gz, pinned-build.tar.gz (VKs), and mock-protocol-circuits/pinned-build.tar.gz into the compatibility test cache prefix
  • This ensures the test re-runs whenever pinned artifacts are updated, preventing the CI cache from masking mismatches

On-chain verification

…act changes

- Remove SponsoredFPC from genesis computation (testnet deployed without it)
- Update expected genesis archive root (verified against on-chain testnet L1)
- Mix pinned artifact archive hashes into compatibility test cache prefix
  so the test cache busts when pinned-protocol-contracts.tar.gz or
  pinned-build.tar.gz change

fix: use git hash-object for pinned artifact hashing
d8e4637 
Replace cache_content_hash (which requires full CI environment) with
git hash-object for hashing pinned archive files directly.
@AztecBot
fix: revert to cache_content_hash for pinned artifact hashing
fda1203 
Previous CI failure was unrelated (docs/example/bootstrap.sh), not
the cache_content_hash call. Restore the correct approach.
