GCDM

1. Kickoff & product direction

• Initialized the project (plan, stack, Ace3, /gcdm, SavedVariables).
• Target shifted from 11.2.7 → 12.1 (Secret Values / Duration Objects / AuraContainer awareness).
• Could not restore discontinued AyijeCDM; decided on a maintainable rewrite instead.
• Committed the plan; started implementation.

2. Core skin pipeline

• Viewer registry for Essential / Utility / Buff / Buff Bar.
• Scoped refresh: STYLE / LAYOUT / GLOW / GROUPS.
• Icon size, border, zoom, spacing, second Essential row size.
• Pixel snap, debug overlays / dumps (/gcdm log, later /gcdm icons).

3. Visual polish (long feedback loop)

• Fixed icon↔border gaps, zoom/mask issues, GCD swipe not filling to the border.
• Jagged swipe edges; glow under/over border; “insanity”-style fill behavior iterations.
• Hide pandemic / red edge chrome; Blizzard proc glow fit/scale/offset + per-button disable.
• Out-of-range / usability tint work; SharedMedia fonts (Expressway via LSM).

4. Layout & Edit Mode

• Custom Essential layout: spacing, max icons per row, row-2 size.
• Many Edit Mode / CDM Settings bugs: overlapping icons, wrong sizes, jagged Y, layout resets when opening Blizzard settings.
• Settled policy:
  • Defer viewer position snaps in Edit Mode UI.
  • Keep GCDM icon layout on.
  • Re-apply layout when CDM settings open/close.
• Power bar must remain visible in Edit Mode.

5. Bars, text, binds, extras

• Power bar: follow Essential width, min width, gap, textures/colors/ticks/curves, class profiles.
• Buff bars: solid/SharedMedia styles, width/height/spacing, icon gap, text visibility.
• Cooldown / stack / keybind / buff-bar name+duration text (per viewer).
• Keybind resolution; press overlay; aura sounds; profile share; migrations; enUS/ruRU.
• Behavior test harness (/gcdm test).
• GitHub remote/push setup when requested.

6. Geometry correctness (later builds)

• Shared Essential stride + border overlap when spacing = 0.
• Essential end gaps trimmed by 0.5 UI units.
• Power bar pin to Essential edges to kill ~2px side overhang vs the icon row.
• Pure math extracted to LayoutGeometry; constants centralized.
