Keep the accelerate polling, gateway gating, telemetry, and directly related tests and test-support changes. Full details: Behavior SafetyExplanation No explicit behavior-safety failure is introduced. The new gate uses the decoded block slot, applies in both CL→MumP2P and MumP2P→CL paths, and keeps arrival and stream recording before the gate. Polling swaps an immutable window atomically, retains it on failed polls, filters negative slots, and fails open for missing or expired coverage. Focused tests cover polling, startup priming, retention, selected and unselected slots, and the gateway CL-delivery path. The configuration and connection-metric changes also preserve their existing tested behavior. Full details: Over-EngineeringExplanation The new acceleration window cache and slot-passing signature changes support required behavior, and the gateway tests assert observable CL and stream outcomes.

Add focused tests for both forwarding gates.
These lines change whether beacon blocks reach Mump2P and the CL topic. Add observable tests that load a selected and an unselected slot, then verify that each inbound path publishes only the selected block. Use the existing gateway test fixture and assert publish results, not internal state.
As per coding guidelines, “Require focused tests for non-trivial behavior changes.” As per path instructions, “Prefer focused tests on changed behavior only.”

Reject a missing slots field before replacing the window.
If a 200 response omits slots or sets it to null, res.Slots is nil. With a positive to_slot, the code stores an empty map and ShouldAccelerateBlock returns false for every slot through the horizon. Preserve the previous window and add a regression test.

Two things, one small and one about coverage. The poll failure log formats a nil error. The gate itself has no test. Nothing asserts that a The staleness check looks like the blocker, but slot sits at a fixed offset in the SSZ payload, so a fixture re-slots to the current slot with an 8-byte write. Deleting the gate and skipping the stream emit each fail the new test. It needed three bits of scaffolding, described on that PR; the notable one is that CL -> mesh I would leave: |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Preserve fail-open behavior before the examined window.
Bootstrap examines only [to_slot-96, to_slot], but this condition classifies every older slot as examined. For example, with to_slot=120, slot 1 is withheld when it is absent from slots, although bootstrap did not examine it. Store or derive the lower bound and fail open below it. Add a focused regression test.
As per coding guidelines, "Flag changed paths that may silently alter semantics or break invariants. Require focused tests for non-trivial behavior changes."

We are not forwarding to the CL at all if this parameter is false correct?
If so, then do we have a way to verify that the messages really reach the CL, e.g. in grafana?
There was a problem hiding this comment.
If propagation_enabled is false, mesh beacon blocks are not published to the local CL (existing fleet-wide kill switch, not the slot gate); Grafana can confirm publishes via mump2p_gateway_cl_published_messages_per_topic_total.
