test: cover the ADR-0012 accelerate gate on the block path - #97
Conversation
ShouldAccelerateBlock was tested in isolation; the wiring that gives it effect was not. Nothing asserted that an unselected slot is actually withheld, or that the gate sits after arrival handling so measurement and the ADR-0011 stream run regardless of the verdict. The staleness check looks like the blocker, since every fixture is a captured block from months ago and processBeaconBlockArrival drops anything more than 3 slots off the clock. 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 and no re-signing. Scaffolding this needed: - an accelerate_slots route on LocalBootstrapServer, so the test drives the real poll rather than a stubbed window - SetPropagationEnabled on AppConfig. rig.AppCfg builds an AppConfig literal and never goes through the loader, which is the only place the propagation atomic was stored, so the fleet-wide switch is off in every newGateway-based test. The loader and the rotator callback now write through the same setter. - pollAccelerateSlots renamed to RefreshAccelerateSlots. The export_test.go hook was not visible outside message_router, so the gateway package could not drive a poll; with the poll exported the hook has nothing left to do. Verified by mutation: deleting the gate, and skipping the stream emit, each fail the test.

Drops the new exported mutator, and makes the CL assertion deterministic. Config: SetPropagationEnabled was an exported mutator on production config whose only new caller was a test, letting any package override the switch the dynamic-config callback owns. Validate now seeds propagationEnabled from PropagationEnabledRaw instead, so a hand-built AppConfig honours the field the same way a loaded one does, and the rig just sets the field. Validate runs only from LoadConfig and the rig, never after a rotation, so nothing clobbers a dynamic value. Configs built via LoadTestConfig are unaffected: that already round-trips through the loader. Assertion: statSendLib is drained by dumpServiceStat, which NewService starts and which runs its body once immediately. The window was tiny but real. The test now subscribes to the CL topic and reads the message back. Publishing the unselected slot first makes ordering carry the negative assertion, so there is no timeout to wait out and nothing to race. Also from review: blockSlotOffset replaces the bare 100, with a length guard; libp2p.NoListenAddrs, since publishing needs no peers; sub and messagesMap moved to t.Cleanup so a failed require does not leak them. Mutations re-checked, all three still fail: gate deleted, stream emit suppressed, and gate fed the clock instead of the header slot.
Second review pass. Validate had grown two writes to runtime state, so a second call on a config already in flight would silently revert a live dynamic-config override, re-enabling propagation an operator had switched off. Only LoadConfig calls it today, so it was latent, but the name promises a check and nothing enforced the ordering the comment relied on. InitDerived now owns every field mirroring yaml/env, Validate is a pure check again, and the doc says plainly that it is not safe on a config already in service. LoadConfig and the test rig both call it. This also picks up the two seeds the rig was missing. skipMessageFromSelf was the one that mattered: rig-built configs read false where production reads true, so the self-message guard on the mump2p block path was inert in exactly the tests that now reach it. aggregationIntervalMs was zero, which disabled the aggregator via its own d > 0 guard; seeding it turned out to be quiet, the suite is unchanged. Also from review: the CL assertion compares the delivered slot rather than the raw block, so a failure prints one number instead of two multi-kilobyte payloads.
Third review pass. blockAtSlot now reads its own rewrite back through DecodeBeaconBlockHeader. The offset is duplicated from the production decoder by necessity, and a drift would otherwise surface as an unexplained 5s timeout rather than pointing at the cause. The negative assertion rested on gossipsub delivering the two publishes in publish order. That holds today, but it is an assumption the test should not need. Review suggested backing it with statSendLib; that counter is drained by dumpServiceStat, which NewService starts and which runs its body once immediately, so it trades an ordering assumption for a timing one. Instead the test now requires the subscription to go idle after the on-list block. Verified by breaking the gate with the publishes reversed: the ordered case fails on the delivered slot, the reversed case fails on the idle window, so both orders are covered. Costs 250ms against local delivery that is immediate. Also folds the duplicated zero-means-default aggregation rule into one helper shared by InitDerived and Validate.

This adds one end-to-end test overprocessMumP2PMessage: an on-list slot reaches the CL, an unselected one does not, and both are streamed either way, since ADR-0012 keeps measurement outside the gate.Fixtures are months old and
processBeaconBlockArrivaldrops anything more than 3 slots stale, so the gate was unreachable. Slot sits at a fixed offset in the SSZ payload, so a fixture re-slots to the current slot with an 8-byte write and no re-signing.Three enablers:
accelerate_slotsroute onLocalBootstrapServer, so the test drives the real poll rather than a stubbed window.AppConfig.InitDerived.rig.AppCfgbuilds a config literal and never goes throughLoadConfig, so the atomics mirroring the yaml/env fields were unseeded: propagation was off in everynewGatewaytest, andskipMessageFromSelfreadfalsewhere production readstrue.Validatestays a pure check.pollAccelerateSlotsrenamed toRefreshAccelerateSlots. Theexport_test.gohook was invisible outsidemessage_router, so the gateway package could not drive a poll. It is deleted.Mutation-checked: deleting the gate, suppressing the ADR-0011 emit, and gating on the clock instead of the header slot each fail the test, in either publish order.
