 - Center-coordinate test first failed on prior left-aligned mapping (0 != 66). New mapping passes at widths 360/400/480 using engine font metrics including 5px spaces. All 32 tests pass; rollback restores the previous copy exactly.

+- Inspected live 12px SimSun atlas: U+3002 ink bounding box `(2,5,6,9)` in a 12x12 cell leaves three empty rows below, reproducing the user's raised punctuation.
+- Anchored only U+3002 to the cell bottom: bbox `(2,8,6,12)`, same eight pixels and shape. All other atlas pixels and bytes remain identical. Updated builder to retain this placement on future generation; `fix_full_stop.py` patches existing TGA without rebuilding other glyphs.
+- Prepared matching loose atlas and in-place same-size `Textures.res` entry; bytes before and after that entry remain identical. No executable, metrics, UV table, script, or other punctuation changes.
+- 34 tests pass. Checked original/fixed glyph bounds and exact shape preservation; rollback of both files tested against backups in an isolated directory. Comparison PNG uses actual atlas pixels enlarged 8x.
+- Backup: `E:/DragonHD/backup_game/full-stop-20260920`. User explicitly authorized terminating the running game for installation. Real in-game appearance pending.
