Load hit and Fogo still wouldn't mis-sequence.
The order still held.
Burst window. Same wallet class. Same pair. I'm waiting for the usual smear... the part where congestion gives you a little blur to hide inside.
It doesn't show.
Fogo SVM PoH just keeps cutting.
Banking doesn't choke. No bulge, no ugly tail. It seals what's ready, flushes on the boundary, opens the next leader window like it never heard the noise. Same shape every 40ms.
I widen the trace.
Wrong slot range. Back. Filter again.
Vote deltas sit near the median. Turbine bands stay tight. No late tail behind the leader. p95 doesn't move. My congestion alarms never even arm.
Under load I expect weirdness. Not failure. Weirdness.
Flat.
Firedancer Validator client threads don't spike. Replay doesn't grow a limp. Scheduler lanes stay even...no tail to bargain with.
So I do it on purpose. I fire a cancel a hair late.
Original lands in slot 19288532.
Cancel accepted in 19288533.
Replace clears in 19288534.
Three windows. No overlap. No argument.
Fill prints against the original before the cancel sees daylight. Replace executes one slot later. Worse price by a few bps. Both valid.
State already moved.
I scroll faster like I can catch the bend mid-air. Compute doesn't flare. Banking latency on Fogo SVM layer-1 holds. Histograms stay clean at the edges.
I try larger size. Heavier write sets usually shake something loose... lock contention, scheduler jitter, some tiny asymmetry you can trade around.
Banking seals.
Vote pipeline extends.
Lockout depth increments. Finality stays inside its window.
Arrival vs execution timestamps stay compressed. Same-slot inclusion or next-slot inclusion. Nothing in between.
"Close" is binary here.
Same slot, or you're already paying it in the next one.
Another burst hits and my finger stalls over cancel.
Leader window narrowing.
If I nudge late again, I already know what happens. Execution prints. Replace lands one slot after. Worse price. Clean ordering.
No smear. No mercy.
So the adaptation is ugly... I start staging cancels earlier than I trust them. The config now has a "Fogo buffer" I didn't name. 12ms. Just sits there. On other chains I'd call it safety. Here it's admission.
New slot forms. Orders stack into it.
My config tab is still open. fee bump logic, latency thresholds, the parts that assumed congestion would distort something.
PoH ticks.
@Fogo Official Leader rotates.
Cancel staged. 12ms early. Not safety... just Fogo. Boundary nearing. The blur I wanted, I'm now building myself.
I send.
