Fix the envelope problem (BLOCKING) +The core issue: checkpoint sync doesn't download/store the execution payload envelope for the checkpoint block. Three approaches: + +**Option A — Download envelope during checkpoint sync (RECOMMENDED)** +- Extend `weak_subjectivity_state()` in `beacon_node/beacon_chain/src/builder.rs` (~line 425) to also download and store the checkpoint block's envelope +- The checkpoint sync server at `https://beacon.epbs-devnet-1.ethpandaops.io/` serves blocks via `/eth/v2/beacon/blocks/{slot}` which contains `signed_execution_payload_bid` +- BUT the envelope itself may need a separate endpoint. Check if `/eth/v1/beacon/execution_payload_envelopes/{block_root}` exists (it 404'd when I tried) +- If the envelope isn't available via HTTP, you'd need to either: + - Add envelope support to the checkpoint sync protocol + - Or compute it: fetch the execution payload from geth for that block hash and construct the envelope + +**Option B — Trigger P2P envelope lookup when missing** +- When `get_payload_envelope(&root)` returns `None`, instead of erroring or falling back, queue an envelope lookup via P2P (similar to how block lookups work) +- PR #68's lookup sync code may already have infrastructure for this — check `single_block_lookup.rs` and `network_context.rs` for envelope request methods +- `request_single_envelope()` exists at `network_context.rs` — this may be usable + +**Option C — Compute Full state from Pending state + payload** +- Load the Pending state, execute the payload against it to produce the Full state +- This requires having the execution payload data and running a state transition +- Complex and not ideal for the sync hot path + +### 2. Peer connectivity issues +- Node connects to 2-7 peers initially but drops to 0 quickly +- This happens even before block processing (the checkpoint sync instance lost peers before any blocks were processed) +- Might be related to: fork digest mismatch, status message incompatibility, or rate limiting +- The genesis sync test (with vibehouse) maintained peers better — investigate why checkpoint sync loses them +- Could also be a gossip subnet issue — the devnet only has ~10 nodes total + +### 3. EL sync coordination +- Geth starts and imports ~157 blocks but then stalls waiting for forkchoice updates from the CL +- Once the CL can process blocks, it will send forkchoice updates and geth will follow +- This is expected and not a bug — it's just downstream of fixing the envelope issue + +## Key Code Locations + +| What | File | Line | +|------|------|------| +| Checkpoint sync init | `beacon_node/beacon_chain/src/builder.rs` | ~425 (`weak_subjectivity_state`) | +| State storage | `beacon_node/store/src/hot_cold_store.rs` | ~1077 (`put_state`) | +| Hot state summary | `beacon_node/store/src/hot_cold_store.rs` | ~4220 (`HotStateSummary::new`) | +| Payload status check | `beacon_node/store/src/hot_cold_store.rs` | ~1864 (`get_hot_state_summary_payload_status`) | +| Parent state loading | `beacon_node/beacon_chain/src/block_verification.rs` | ~1960 (`load_parent`) | +| Envelope storage | `beacon_node/store/src/hot_cold_store.rs` | ~1064 (`put_payload_envelope`) | +| Envelope retrieval | `beacon_node/store/src/hot_cold_store.rs` | ~741 (`get_payload_envelope`) | +| Envelope P2P request | `beacon_node/network/src/sync/network_context.rs` | search for `request_single_envelope` | + +## Files Modified (uncommitted) + +1. **`beacon_node/store/src/hot_cold_store.rs`** — Bug 1 fix: handle missing previous_state_root summary in `get_hot_state_summary_payload_status` +2. **`beacon_node/beacon_chain/src/block_verification.rs`** — Bug 2 workaround: fallback to Pending when envelope missing + added `warn` to tracing imports + +## What's NOT the Problem +- Build: compiles fine in release (~2-4 min incremental) +- EL: geth syncs and connects, authrpc works +- P2P boot ENRs: correct, 11 entries, work for genesis sync +- Checkpoint sync download: block and state download fine +- Config: correct network config, fork schedule, genesis state + +## Useful Commands +```bash +# Check sync status +curl -s http://127.0.0.1:5053/eth/v1/node/syncing | jq . + +# Check devnet head +curl -s "https://beacon.epbs-devnet-1.ethpandaops.io/eth/v1/beacon/headers/head" | jq '.data.header.message.slot' + +# Check geth +docker logs geth-devnet-1 2>&1 | tail -20 + +# Check CL logs +tail -50 /tmp/lh-devnet.log + +# Rebuild after changes +export PATH="$HOME/.cargo/bin:$PATH" +cd /root/.openclaw/workspace/lighthouse-devnet-test +cargo build --release --bin lighthouse + +# Restart clean +pkill -f "lighthouse-devnet-test" 2>/dev/null;
