The /eth/v1/beacon/execution_proofs/{block_root} endpoint returns each
proof wrapped in a signed envelope ({message: {proof_type, proof_data,
public_input}, validator_index, signature}) and does not include slot,
block_hash, or block_root. The previous struct expected those fields at
the top level, so every proof unmarshalled empty and tripped a
"strconv.ParseUint: parsing \"\"" warning, leaving the proofs panel
blank.
Match Lighthouse's actual schema, decode proof_data from hex, and source
slot/block_root/block_hash from the slot page context.

The `div` template helper requires float64 args, but `len` returns int, so rendering any execution proof larger than 1 KB raised "wrong type for value; expected float64; got int" and 500'd the slot page. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Match the convention used for attestations, transactions, and other slot-page tabs. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
/eth/v1/beacon/execution_proofs/{block_root}Lighthouse endpoint returns each proof wrapped in a signed envelope ({message: {proof_type, proof_data, public_input}, validator_index, signature}) — not the flat{slot, block_hash, block_root, proof_data}shape Dora expected after Display optional execution proofs #593.Error parsing proof slot error="strconv.ParseUint: parsing \"\": invalid syntax", and the proofs panel was always empty.ExecutionProofto match Lighthouse, decodeproof_datafrom hex, and sourceslot/block_root/block_hashfrom the slot page context (since the API doesn't include them).Test plan
