Confirmed → Finalized

X-axis — the confirmed→finalized delta, in seconds — for each bundle, how long it took to go from “two-thirds voted” (confirmed) to irreversible (finalized), grouped into 0.25 s buckets.

Y-axis — count — how many of the 16 bundles fell into each bucket (they sum to 16).

The distribution is tight around ~12 s because finalization is near-deterministic — a block finalizes ~32 slots after it is produced. The dashed line marks that ~32-slot depth; the orange line is the median.

Why it matters for blockhashes: that ~12 s is exactly the staleness a finalized blockhash carries before you even submit — ~32 of your 150 validity slots, gone up front. (The README's blockhash-budget figure visualizes that trade against confirmed.)
