The payload_inclusion_list_satisfaction map in fork choice was never being
populated. This meant should_extend_payload always returned false, causing
the Empty/Full tiebreaker to always favor Empty — resulting in payload
envelopes being orphaned even when they satisfied the inclusion list.
After importing a valid execution payload envelope, check whether its
transactions satisfy the cached inclusion list entries for that slot and
record the result in fork choice. This allows the tiebreaker to correctly
favor Full when the IL is satisfied.
Remove non-spec attestation deadline check that was incorrectly
rejecting ILs arriving in the first 1/3 of the slot. Per the heze
p2p-interface spec, ILs are valid when message.slot == current_slot
(with MAXIMUM_GOSSIP_CLOCK_DISPARITY allowance).
Also accept current_slot + 1 for clock disparity tolerance.
When engine_newPayloadV6 fails with a transient error (e.g. Besu's
ConcurrentModificationException), queue the envelope for retry instead
of permanently rejecting it. Matches Lodestar's behavior of retrying
on the next BlockImported event.
- Add RetryEnvelope variant to ReprocessQueueMessage
- On BlockImported, immediately dispatch any pending retry envelopes
- Fallback timeout of 1 slot in case no block arrives
- Max 3 retries per envelope to prevent infinite loops
- Only retry non-penalizing EL errors (transient failures)
In ePBS/Gloas, the execution payload is delivered via envelope, not
embedded in the beacon block. produce_inclusion_list was trying to
extract parent_hash from the beacon block's execution payload (which
doesn't exist), causing every IL fetch to fail.
Use cached_head.head_hash() which correctly tracks the execution
block hash through fork choice, including envelope imports.
Besu does not implement this method. Lodestar handles IL satisfaction
checking via the il_transactions param in newPayloadV6 instead of a
separate engine call. Skip the call and assume satisfied for now.
- Force engine_newPayloadV6 for Heze blocks (Besu supports V6 but
capability detection was falling through to broken V5 path)
- Pass parentHash to engine_getInclusionListV1 (was sending empty
params, Besu/Lodestar expect the parent block hash)
We have a legacy `TestRandom` trait which generates random types for testing and fuzzing.
This function overlaps with `arbitrary` which is used very commonly in the ecosystem.
Remove `TestRandom` and generate random type instances using `Arbitrary`.

Addresses issue #9220
The `payload_attestation_data` endpoint returns 400 when no block has been received for the requested slot. This causes the VC to log at CRIT level for what is expected behaviour per spec: validators should simply not submit a payload attestation when no block has been seen.
- Return 404 (Not Found) instead of 400 from `payload_attestation_data` when no block exists for the slot. This is consistent with other beacon api endpoints.
- Downgrade the VC log from `crit` to `debug` when a 503 is received, since this is an expected no-op per spec.
- Add `BlockNotFound` rejection type to `warp_utils`.
- Add a test asserting the 404 response for an empty slot.

Fixes a flaky CI failure in `data_column_reconstruction_at_deadline` where 2 `column_reconstruction` events are emitted instead of the expected 1.
- Change `queued_column_reconstructions` from `HashMap<Hash256, DelayKey>` to `HashMap<Hash256, Option<DelayKey>>`, where `None` indicates reconstruction was already dispatched.
- On dispatch (`ReadyColumnReconstruction`), set the entry to `None` instead of removing it. This prevents a subsequent gossip column from inserting a fresh reconstruction request into the now-vacant slot.
- Prune stale `None` entries on each dispatch to keep the map bounded.

- Avoid sending 0x00 block hashes for the safe and finalized block hashes post-Gloas.
- Add code to check this inside the mock EL, which will be reached in all Gloas beacon chain tests

We yolo'd to alpha 7. We're just changing the proposer preference to include dependent root, instead of checkpoint root. This way we can actually construct it within the VC without needing a view of fork choice.

- test_utils: Heze branch uses DataColumnSidecarGloas (shared format), keeps
heze_enabled() check ahead of gloas_enabled() so Heze blocks are handled first
- genesis.rs: Keep both Gloas and Heze bid initialisation in genesis_block()
