新增可选第四委托「远距取证」：40m 处 1.2×3.2m 编号板 D40，夜间场景、静止。320 宽母片上板高要 ≥30px，并仍过原来的进光与总糊门槛。
板高与拖影共用同一放大率。28/50/85 在 40m 的投影高约 11.2 / 20.0 / 34.1px，只有更长焦距才能让远处的字够大。触控放大区不是成像尺寸。
原三项委托的公式、几何、命中与门槛不变。换镜组或旋钮只改实时取景；已拍底片连同当时的板高一起冻结。预览不算过关，按快门才记入。

In the same commission you can pin an already taken print as a reference and compare it with a later, non-adjacent print: lens, focus, aperture, shutter, exposure, subject blur, and pass or fail.
Switching commission or restarting clears the pin. The full print history stays. Live preview cannot be pinned as a print.

The motion-ok chip now says “No motion blur”. It only reports smear, not whether glyphs are optically readable when the subject is defocused.

Optional fourth commission: a 1.2×3.2 m identifier board D40 at 40 m, night scene, static. On the 320-wide master the projected board height must be ≥30 px, plus the original brightness and blur gates.
Board height uses the same magnification as motion smear. At 40 m the 28 / 50 / 85 mm lenses project about 11.2 / 20.0 / 34.1 px; only the longer lens makes distant glyphs large enough. The 48 px touch box is not image height.
The original three commissions keep their numbers, geometry, hits and thresholds. Changing lens or dials updates live view only; frozen prints keep the sampled board height. Preview is not a pass; a real shutter sample scores the task.

The live viewfinder image stays on screen with up to two frozen prints. You do not have to open the comparison dialog first.
The live thumbnail is the current viewfinder. Prints label exposure, defocus and smear. Later dial moves do not rewrite old frames. Live preview is not a commission score.

Viewfinder, aperture ring, shutter dial and prints are distinct. Tap a subject to focus. One control is primary, while exposure, depth of field and smear stay visible together.
Portrait: viewfinder above, camera body below. Landscape: viewfinder with side dials. The landscape bench is not scaled down to fit a phone portrait.
Each print freezes the actual settings at the shutter press so two frames can be compared. Optical rules, thresholds, commissions and history are unchanged. A saved classic preference remains.

A photographic viewfinder with separate portrait and landscape layouts. Tap a subject to focus, then choose shutter, aperture or focus controls.
Each shutter press freezes the actual image and settings. Compare it with the previous frame; later adjustments and task changes leave photos unchanged. Restarting clears the session film.
Lens options, task details and view preferences are in settings. Saved classic preferences remain available. Optical rules and acceptance thresholds are unchanged.

The optical bench and viewfinder are now the default view. Switch to the classic view while keeping current settings and sample progress.
Live previews and confirmed samples remain separate. Parameter changes mark earlier samples as no longer matching the current settings.
Review the recorded sample settings for all three commissions, with current settings and historical samples labelled separately.
