pad_context — DRIVE pegtactile op

• Data kinds: table → table

• Call: import fullseye as fs; fs.ledger.pad_context(pad: 'dict', jitter_px: 'float' = 0.5, seed: 'int' = 7) -> 'dict' (to call the implementation directly, import pegtactile; pegtactile.pad_context(pad: 'dict', jitter_px: 'float' = 0.5, seed: 'int' = 7) -> 'dict'; from the registry, opsdrive.get("pad_context"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

膜の合成と読みで 1 回だけ作る道具: 画素中心の格子 (X, Y)、Cerruti 核、3 色の光源、無荷重の膜の背景とマーカーの基準像。

マーカーは `jitter_px` の一様ジッタで位相を散らす(印刷のばらつき程度)。**規則格子(0 px)は全マーカーが同じ副画素位相なので、

重心の pixel-locking が場全体の共通モードになり、せん断ゼロでも偽のせん断が出る**(PoC の門で 11 mN → 0.9 mN)。

`seed はジッタの乱数。返りの _model_cache・_sr_cache` は読みの内部キャッシュ。Raises ValueError: jitter < 0。
