Consensus EigenDA V40

WAVM Module Root: 0x2c9a9d645ae56304c483709fc710a58a0935ed43893179fe4b275e1400503ea7

This consensus release supports ArbOS 40 w/ EigenDA.

v3.5.7: Stateless EigenDA Enablement Support

Containers: nitro-node, nitro-node-dev
Replay Artifact: consensus-eigenda-v32.3

This release introduces a simplification by removing EigenDA enablement from the L2 system config - effectively making it stateless. Having EigenDA as a first class citizen by being explicitly declared within global state created headaches for customers; i.e:

• Migrations from existing Arbitrum chains required performing additional operations by needing to enable EigenDA
• New chain deployments against an EigenDA RollupCreator contract required using a genesis system config with EigenDA=true.

For more context on the exact problem statement and proposed solution - please advise specification here.

NOTE: Properly upgrading to this version requires updating the wasm module root on your parent chain, this can be done via calling your Rollup contract's setWasmModuleRoot method via your UpgradeExecutor contract.

What's Changed

• feat: Make EigenDA enablement stateless by @ethenotethan in #108
• chore: Update Dockerfile to include v32.3 consensus release by @ethenotethan in #109

v3.5.6: Fix EigenDA Failover and Max Batch Size Limits

Containers: nitro-node, nitro-node-dev
Replay Artifact: consensus-eigenda-v32.2

This release addresses a critical validation bug affecting EigenDA message handling, introduces a fix for improper header parsing, and updates configuration defaults to prevent blob size overflows. Anyone running an earlier version is recommended to switch immediately.

NOTE: Properly upgrading to this version requires updating the wasm module root on your parent chain, this can be done via calling your Rollup contract's setWasmModuleRoot method via your UpgradeExecutor contract.

Bug Fix: Incorrect EigenDAHeaderByte Parsing

A critical issue was identified where validations failed due to the EigenDAHeaderByte being incorrectly set to 0xED. This value, when evaluated using bitwise AND with the hasBits mask against AnyTrust message header byte (0x80):

   11101101   (0xED)
&  10000000   (0x80)
-----------
   10000000   (result)

...falsely signaled that the message should be processed by an AnyTrust reader, even though it was an EigenDA sequencer message.
This behavior went undetected in our system tests due to a commutativity violation: the construction order of dapReaders differed between the replay and live node environments.

Fix: An override was introduced in the header verification logic to correctly interpret the EigenDAHeaderByte and prevent misclassification. Furthermore strict isomorphism with dapReaders initialization has been enforced across execution environments.

Configuration Fix: MaxEigenDABatchSize

The default MaxEigenDABatchSize was previously set to 16 MiB. However, when a rollup payload of exactly 16 MiB was dispersed, the EigenDA proxy would pad it to the next power of 2, exceeding the maximum allowed blob size and causing dispersal to fail.

Fix: The default value has been updated to ensure the payload, once encoded into blobs, does not exceed the 16 MiB limit.

Summary
