# The Fall — slightly tighter partial line protection
|
||
|
||
Compare `the-fall-extraordinary-v7-pane-coverage-tight-normal-1000` with `the-fall-extraordinary-v7-pane-coverage-normal-1000` in the harness. Reload or reopen the Card selector to refresh the catalog. The artwork, lettering, text mask, pane coverage, line-detection neighborhoods, overlay protection and shader settings are identical.
|
||
|
||
The only changed parameter is **lead-protection gamma: 1.00 → 0.85**. Protection becomes `protection ** 0.85` before the existing high-confidence clamp. This strengthens already detected partial protection (0.50 becomes approximately 0.555) without changing zero/full protection. It reduces finish on pale seam transitions; it does not globally dim pane interiors or identify new semantic pane boundaries.
|
||
|
||
| Parameter | Previous | Tight |
|
||
|---|---:|---:|
|
||
| Pane mask strength | 0.62–0.90 | unchanged |
|
||
| Saturation weighting thresholds | 0.08–0.58 | unchanged |
|
||
| Saturation smoothing radius | 20px | unchanged |
|
||
| Dark-ridge closing radius | 15px | unchanged |
|
||
| Ridge contrast thresholds | 0.025–0.085 | unchanged |
|
||
| Ridge brightness gate | 0.12–0.23 | unchanged |
|
||
| Line-analysis smoothing radius | 1.2px | unchanged |
|
||
| Coherence opening radius | 1px (3×3) | unchanged |
|
||
| Full-protection clamp threshold | 0.97 | unchanged |
|
||
| Partial-protection gamma | 1.00 | **0.85** |
|
||
|
||
All radii refer to the 2000×2800 master canvas. The change lowers 268,860 pixels in the 1000px map, averaging 1.04/255 across the entire texture, with a maximum reduction of 14/255. No pixel receives more finish. Some pale or textured areas remain because the detector still estimates divisions from raster pixels; this is a small comparison adjustment, not semantic pane tracing.

Build staged masks with:
|
||
|
||
```sh
|
||
python3 build-mask.py
|
||
```
|
||
|
||
Registered opaque grayscale maps are exported at 2000, 1000 and 500 pixels. The baseline and all pre-existing runtime PNGs are preserved. The separate candidate is installed in `../../card-harness/public/card-art/`; material comparison remains with the user. No typography, artwork, substrate settings, extra runtime textures or other printing masks are changed.
