feat(sentry): land execution_payload / _gossip SSE events (flat shape) - #868
Merged
Conversation
The EIP-7732 execution_payload and execution_payload_gossip beacon-API events
carry a flat payload summary — {slot, builder_index, block_hash, block_root,
execution_optimistic} — not a full SignedExecutionPayloadEnvelope (see
beacon-APIs apis/eventstream/index.yaml). The sentry decoded them as the full
envelope, so every event failed to parse ("message missing") across all six CL
clients and both tables stayed empty since the glamsterdam rollout.
- Repin go-eth2-client + beacon to the builds that decode the flat event into
api/v1.ExecutionPayloadEvent and route it through the broker.
- New xatu proto ExecutionPayloadEvent; DecoratedEvent fields 249/255 repointed
from SignedExecutionPayloadEnvelope to it.
- Rewrite both sentry handlers + route flatteners to the flat shape.
- Migration 009 reshapes the (empty) tables to match the event: drop the
vestigial state_root + slot_number columns, add execution_optimistic to the
execution_payload table (the gossip event omits it, so its table does too).
Regenerated route .gen.go + proto; snapshot tests pass against a live
ClickHouse and parse the real captured wire samples.

- Remove now-unused execution_payload_envelope.proto import (buf lint) — no DecoratedEvent field references SignedExecutionPayloadEnvelope anymore. - Repin go-eth2-client + beacon to the merged #39/#78 commits. - Bump quic-go v0.59.0 -> v0.59.1 (GO-2026-5676).

The EIP-7732
execution_payload/execution_payload_gossipbeacon-API events carry a flat payload summary (slot, builder_index, block_hash, block_root, execution_optimistic), not a fullSignedExecutionPayloadEnvelope, so the sentry failed to parse them ("message missing") across all six CL clients and both tables stayed empty since the glamsterdam rollout. This repins go-eth2-client (#39) + beacon (#78) to decode the flat event, repoints the proto + handlers + route to it, and adds migration 009 reshaping the (empty) tables to match — dropping the vestigialstate_root/slot_numbercolumns and addingexecution_optimisticto the non-gossip table.Merge order is go-eth2-client#39 → beacon#78 → this, and migration 009 must deploy in lockstep with the consumoor image. Depends on ethpandaops/go-eth2-client#39, ethpandaops/beacon#78.
