As mentioned on our last sync, I would prefer we try to keep reth 2.0 state compatible so we can roll this out without an EL hard fork. We can consider updating the gaslimit in future more lightweight el hf.

Still testing.
Next steps are running this live on a devnet and migrating validator nodes from v1 to v2 incrementally and ensure network stays live. Would definitely help to start code review.. I'll open this PR once these tests are done. |

Quick review, looks good, will wait for devnet testing and verification for a more detailed review.

- This conversion consumes only

- The PR description says byte-identical payload IDs are pinned by preserved vectors, but these assertions only compare IDs to each other. Any common change to the hash inputs or encoding still passes. Restore fixed expected payload-ID values generated by the pre-upgrade implementation.
// Test via PayloadAttributes::payload_id which calls berachain_payload_id
let id_no_pubkey = attributes_no_pubkey.payload_id(&parent);
let id_with_pubkey = attributes_with_pubkey.payload_id(&parent);
// Critical test: presence of pubkey should affect payload ID

In @.github/assets/hive/run_simulator.sh:
- Line 5: Update the directory change in run_simulator.sh so the script exits
immediately when changing to hivetests/ fails; preserve the existing
working-directory behavior on successful navigation.
- Line 29: Replace the predictable /tmp/log path in run_simulator.sh with a
mktemp-created file, store it in a variable, and use that variable both in the
tee pipeline and check_log. Add a trap to remove the temporary log on script
exit while preserving the existing logging behavior.

so invocations providing only simulator and limit arguments use the same default
as build_simulators.sh, allowing the existing Osaka EELS Amsterdam guard to
apply in CI.
In `@CLAUDE.md`:
- Line 29: Label the fenced directory-tree block in CLAUDE.md with the text
language by changing its opening fence to a text fence, while preserving the
block contents and closing fence.
In `@src/engine/payload.rs`:
- Around line 37-39: Update payload_id and berachain_payload_id to include
target_gas_limit in the payload ID using a presence marker followed by the
optional value as big-endian u64, ensuring different limits produce distinct
IDs; add a regression test covering differing target gas limits.
- Around line 253-259: Update the From<BerachainBuiltPayload> for
BerachainExecutionData implementation to pass value.requests into the V4 sidecar
conversion instead of discarding it through block_to_payload. Preserve request
bytes for non-empty Requests and add a test verifying the converted sidecar
retains them.
In `@src/evm/mod.rs`:
- Around line 253-256: Remove the inline system-call rationale comments at
src/evm/mod.rs lines 253-256 and the inline POL commit comments at

- This V1 description conflicts with the migration tests and actual layout: unpruned V1 receipts already reside in static files (

The V1 layout stored everything in a single MDBX database. V2 splits storage by access

Upgrade to Reth SDK v2.5.0 (Storage V2)
Upgrades bera-reth from reth v1.11.4 to reth v2.5.0 (initially v2.4.0, bumped in-flight), adopting the Storage V2 datadir layout and migrating every touched API surface. Behavior is intentionally preserved: no new opt-in reth features are enabled, engine runtime defaults are pinned to their pre-upgrade values, and on-disk formats are locked by golden byte-vector tests.
