#32: git diff/ls-files при дефолтном core.quotePath=true возвращают кириллицу в octal-виде → объект с кириллическим именем не распознавался в partial-load. Все git-вызовы теперь с `-c core.quotePath=false`. PY — в центральном run_git; PS — унифицировал inline-вызовы в хелпер Invoke-GitLines (паритет с py). v1.11. #33: img-grid падал ZeroDivisionError при -c 0 / некорректном -r. Добавлена валидация (cols>0, rows>=0, auto-rows max(1,...)). Pillow задокументирован как runtime-зависимость (README + python-porting-guide). overlay-grid.py получил версионный заголовок (v1.1). Тесты: runner error-кейсы db-dump-dt/db-load-dt/db-load-git (из PR #34). img-grid runner-кейс не вводили (py-only + Pillow-зависимость) — #33 проверен вручную.

# img-grid v1.1 — Overlay numbered grid on image
|
|
# Source: https://github.com/Nikolay-Shirokov/cc-1c-skills

"""Overlay a numbered grid on an image to help determine column/row proportions.
|
|
|
|
Usage: python overlay-grid.py <image> [-c COLS] [-r ROWS] [-o OUTPUT]
|
|
|
|
The grid helps an LLM count "squares" to determine exact column widths
|
|
and positions when analyzing printed forms for MXL template generation.
|
|
|
|
Numbers are rendered in a dedicated margin band outside the image content,
|
|
so they never overlap with the form and remain readable at any grid density.
