+## ClassicAPI-first conversion audit — 2026-08-30
+
+The retained Extras modules were audited again against the current ClassicAPI
+API surface. The goal of this pass is the same architecture as
+ShaguTweaks-ClassicAPI itself:
+
+```
+Extras module
+    ↓
+ShaguTweaks.API
+    ↓
+ClassicAPI first
+    ↓
+central Vanilla fallback only when required
+```
+
+The conversion is paired with the ShaguTweaks-ClassicAPI branch
+`extras-classicapi-bridge`, which adds normalized wrappers for macro spell
+resolution, combat/focus verbs, debuff types, reach-aware unit range and
+container item link/count data.
+
+### Direct ClassicAPI-first modules
+
+- **Bag Item Click** — modifier state and container hyperlink via the bridge.
+- **Bag Search Bar** — container item ID/name/link via the bridge.
+- **Macro Icons** — `GetActionInfo` and `GetMacroSpell` via the bridge.
+- **Macro Tweaks** — container/item lookup plus `StartAttack`, `StopAttack`,
+  `FocusUnit` and `ClearFocus` via the bridge.
+- **Enable Raid Frames** — reach-aware `UnitInRange` and modifier state via
+  the bridge.
+- **Show Dispel Indicators** — normalized `GetDebuffType` via the bridge.
+- **Show Bags** — Shift/Control state via the bridge.
+- **Show Micro Menu** — Shift/Control state via the bridge.
+
+### Indirect ClassicAPI-first module
+
+- **Reagent Counter** uses the shared `ShaguTweaks.GetItemCount` helper. That
+  helper now obtains stack counts, item IDs and item names through
+  `ShaguTweaks.API`, so the module receives ClassicAPI container/item data
+  without duplicating API logic locally.
+
+### Modules intentionally remaining on native APIs
+
+The other retained modules were checked individually. Their relevant operations
+are FrameXML/UI functions or Vanilla game functions for which ClassicAPI does
+not expose a replacement required by this addon:
+
+- Dragonflight Gryphons
+- Floating Actionbar
+- Center Vertical Actionbar
+- Center Text Input Box
+- Enable Text Shadow
+- Chat Timestamps
+- Show Aggro Indicators
+- Show Combat Feedback
+- Use Compact Layout
+- Show Group Headers
+- Show Healing Predictions
+- Hide Party Frames
+- Use As Party Frames
+- Reveal World Map
+
+Examples include `CreateFrame`, anchoring/layout methods, chat-frame
+`AddMessage`, `UseContainerItem`, `GetContainerNumSlots`,
+`UnitHealth` / `UnitMana`, and WorldMap FrameXML functions. Replacing these
+with invented wrappers would add abstraction without adding ClassicAPI value.
+
+ClassicAPI does not currently expose an authoritative threat API, so
+**Show Aggro Indicators** keeps its cached target/target-of-target heuristic.
+
+### Central bridge additions
+
+The paired ShaguTweaks-ClassicAPI branch adds:
+
+- `API.GetMacroSpell`
+- `API.StartAttack`
+- `API.StopAttack`
+- `API.FocusUnit`
+- `API.ClearFocus`
+- `API.GetDebuffType`
+- `API.UnitInRange`
+- `API.GetContainerItemLink`
+- `API.GetContainerItemStackCount`
+
+`API.UnitInRange` prefers ClassicAPI's reach-aware 40-yard implementation.
+It explicitly handles the player's own frame and keeps the old interaction
+check only as a centralized compatibility fallback.
+
+`API.GetDebuffType` normalizes the different return layouts of
+ClassicAPI's positional aura API and Vanilla 1.12 `UnitDebuff`, so Extras no
+longer needs to branch on those signatures itself.
+
+### Conversion result
+
+No retained Extras module now performs its own ClassicAPI-versus-Vanilla
+selection for the converted API families. That policy lives in
+`ShaguTweaks.API`, matching the architecture of the main
+ShaguTweaks-ClassicAPI fork.
