Add EIP: ePBS Mandatory Burn of Execution Rewards - #12130

Drop tax/income wording that could imply the burn is a levy on proposer
income. State that the protocol removes the burn from the builder's
gross bid before the proposer payment, so the burned portion is never
proposer revenue.

Rework the backwards-compatibility fallback to reuse the existing
value field in place instead of adding a gross_value field, which
avoids changing the ExecutionPayloadBid container layout.

Collapse Reference Implementation to a pointer: its helper duplicated
the Specification helper and its 14-item list restated the spec.

Remove the Security burn-observability subsection, which repeated the
Specification burn-observability and supply-accounting rules.

Reduce the attester subsection to its one normative line, and replace
the duplicated self-build risk text with a cross-reference.

Specify Gwei priority-fee accounting and Engine API results, encode deferred payable settlements, and bound PTC floor enforcement to a frozen same-slot view. Add incentive and adversarial analysis while consolidating rationale, tests, and security text to keep the unified EIP smaller.

Reject bids that would overwrite an unresolved settlement and require older vector entries to finalize before epoch rotation. Clarify that the one-slot PTC floor is probabilistic enforcement and can permit later canonicalization after expiry.

Mark the bid-floor domain as pending consensus-spec allocation, define priority-fee Engine API fields only for VALID responses, label floor vectors in ETH, and clarify testnet burn configuration. Align remaining security terminology with settlement rotation.

Aggregate priority fees in Wei and commit the resulting Gwei auction credit in signed bids so deferred settlement remains independent of uncommitted Engine API results.

Add objective floor evidence checks and bid-by-root recovery, define the zero-rate kill switch and PAYABLE/INVALID transitions, and update the rationale, security analysis, and test vectors.

Resolve payable settlements immediately when their stored priority-fee credit is zero, including the zero-numerator configuration, and limit payload-outcome dependencies to nonzero-credit entries.

Add lifecycle coverage, qualify floor-setting builder liability under EIP-7732, define the F/G metric for positive G, and retain the marginal credit explanation.

Keep below-floor subtrees filtered through the following slot so an honest proposer can create a competing branch, and document the resulting probabilistic deterrence condition.

Add a configurable haircut to the robust PTC floor, coordinate pre-proposal timing and evidence retention, clarify activation and information leakage, and update evaluation metrics and test cases.

Define next-slot proposer behavior as ordinary head selection after excluding the filtered subtree, and prevent bids or reports from crossing parent contexts.

Document short-reorg risk and self-build fallback, refine the deterrence loss term, and add post-reorg availability metrics and coverage.
