Re-fit the view-dependent settings to the camera's zoom step from 2 to 3

[ciaran-finnegan]

Why

The camera's zoom was stepped from position 2 to 3 at 08:45 today, to put more pixels on a plate at the stop. The silver pickup (172L66) stops with its plate 197–274 px wide, and on 6 Oct it waited about 50 s with 66 misread as 68/88/61. Settings fitted to the old view need re-fitting.

Measured

A 4K still at each position, matched with ORB features and a RANSAC similarity fit (1436 of 1500 matches were inliers). The analysis recovers a synthetic ×1.06 exactly.

	zoom 2	zoom 3
focus (autofocus)	78	97
sharpness	0.233	0.234
scale	1	×1.0556, centred at (0.501, 0.480), no rotation

What

• GATE_LOCAL_SWEEP_CLOUD_MIN_PLATE_PX default 220 → 232 (×1.056).
• GATE_EARLY_TRIGGER_PATCH default → 0,0.248,0.338,0.338: the same square, scaled and started at the left edge.
• GATE_PLATE_REGION unchanged, on purpose. The sweep crops at native 4K and then scales to 1920. Mapping the band outward would cancel the gain exactly; keeping it in place passes the 5.6 % through. The ~2.5 % of scenery lost at each edge holds no measured plate position.
• Camera notes: a new "Zoom step to position 3" section, covering the measurements, why each setting moved or didn't, the camera's own detection zone (unchanged, the lane stays inside it), the refocus nudge (now 3 → 4 → 3), and rollback.

Testing

Full suite 2489 OK (6 skipped). Defaults tests updated deliberately.
