The pre-merge thresholds were tuned against a mock that injected +18 gusts. In
the actual storm_02, gusts-over-baseline peak at 12.1 m/s — so stumbleGust:17
was above every gust in the game and StumbleBack was unreachable dead code, and
shoveGustMin:8 (a low bar in the prototype's 12-38 units) had become a high bar
in ours and threw away most of the shove.
Retuned against the real storm profile (12 gust events, peaks 12.1..6.1, 4
knockdowns, maxExposure 1.55): stumbleGust 17→9, shoveGustMin 8→4. A wild night
now reads shoved (26s of 90) → stumbling (4) → floored (2); a calm day stays 0/0.
d.test.js now loads the real storm JSON via weather.loadStorm and asserts every
threshold is REACHABLE and correctly ordered — the guard the first tuning lacked.
This matters because decision 8 (B+C) reweights the downdraft this sprint, which
is exactly the kind of change that silently killed StumbleBack the first time.
Also pinned the emergent 'unbrace into a gust → stumble' behaviour.
