+# ClassicAPI Adoption Backlog
+
+Opportunities to use [ClassicAPI](https://github.com/) (`C:\Git\ClassicAPI`, see
+`docs/API.md`) in SuperCleveRoidMacros. ClassicAPI is a client mod (sibling to
+nampower/SuperWoW) that backports the modern `C_*` API into the 1.12.1 client.
+We already gate nampower behind version detection — every ClassicAPI path below
+must follow the same pattern: **feature-detect, then fall back to the current
+implementation** so users without ClassicAPI are unaffected.
+
+API references are line numbers into `C:\Git\ClassicAPI\docs\API.md`.
+
+---
+
+## Tier 1 — high impact (new capabilities, not just refactors)
+
+### 1. `C_UnitAuras` — native aura data for any unit
+- **API:** `API.md:8670` — `GetAuraDataBySpellName(unit, name, filter)`,
+  `GetUnitAuraBySpellID(unit, spellID, filter)`, `GetAuraDataByIndex`.
+- Returns `spellId`, `dispelName` (`"Magic"`/`"Curse"`/`"Disease"`/`"Poison"`),
+  `applications` (stacks), `duration`.
+- **Unlocks:** `[dispellable]` / `[curse]` / `[magic]` target conditionals and
+  spellID-based (rank/locale-proof) aura matching.
+- **Replaces today:** pfUI libdebuff + tooltip scanning (`Conditionals.lua:1815+`).
+- **Caveat:** `expirationTime` is only populated for `unit=="player"`; it's `0`
+  for target/focus (vanilla server limitation). Target debuff *timers* still
+  need the existing libdebuff tracking — only presence/stacks/school/spellId
+  are reliable cross-unit.
+
+### 2. `C_Item.GetWeaponEnchantInfo()` — temp-enchant IDs
+- **API:** `API.md:7159` — returns 12-tuple including `enchantID` for main/off/ranged.
+- **Unlocks:** `[poison:<id>]` / `[weaponenchant:<id>]` conditionals — detect
+  *which* poison/oil/sharpening stone is applied, not just that one exists.
+- Vanilla's global only reports presence; this is a genuinely new capability
+  (rogue/shaman/enhance).
+
+### 3. `GetUnitSpeed(unit)` + `IsFalling()` / `IsSwimming()`
+- **API:** `API.md:8312`, `API.md:7629`.
+- **Replaces today:** MonkeySpeed addon dependency (which needs SuperWoW
+  `UnitPosition`) for `[moving]` — `Conditionals.lua:2981`.
+
+---
+
+## Tier 2 — replace custom scanning / extra deps
+
+### 4. `C_Spell.*` / `GetSpellInfo(spellID)`
+- **API:** `API.md:6649+` — `GetSpellCooldown`, `IsUsableSpell`, `IsSpellKnown`,
+  `SpellHasRange`, `GetSpellSchool`, `FindSpellBookSlotByID`.
+- **Replaces today:** spellbook scanning via `GetSpellName(i, BOOKTYPE_SPELL)`
+  (`Conditionals.lua:2500`) and the Slam-slot hack. Simplifies `[known]`,
+  `[usable]`, range checks.
+
+### 5. `C_Timer.After` / `NewTicker` (+ coroutines)
+- **API:** `API.md:8008+`.
+- **Replaces today:** manual `OnUpdate` frames (`Core.lua:5082`, `:80`, `:460`)
+  and the UnitXP aura-cleanup timer (`Conditionals.lua:1474`).
+
+### 6. `UnitGUID` / `UnitTokenFromGUID`
+- **API:** `API.md:8206+`.
+- **Replaces today:** SuperWoW GUIDs in ComboPointTracker (`ComboPointTracker.lua`).
+- **Verify first:** confirm GUID string format matches SuperWoW's before swapping.
+
+### 7. Native `focus` token + `FocusUnit`/`ClearFocus` + `PLAYER_FOCUS_CHANGED`
+- **API:** `API.md:2624+`.
+- **Replaces today:** custom/pfUI focus resolution (`Conditionals.lua:5799`, `:3148`).
+  Gives engine-backed `@focus` for non-pfUI users.
+
+---
+
+## Tier 3 — situational
+
+- **`C_NamePlate.GetNamePlates()` / `nameplateN` tokens** (`API.md:5742+`) —
+  alternative to UnitXP enemy enumeration for AoE counting (`Conditionals.lua:3099`).
+- **`GetShapeshiftFormID()` + `UPDATE_SHAPESHIFT_FORM`** (`API.md:7792`) —
+  cleaner stance/form conditionals.
+- **`CastSpellNoToggle` / numeric spellIDs in `/cast`** (`API.md:5336+`) —
+  rank-specific casting by ID, no-toggle behavior; could back a `/cast <spellID>`.
+- **State helpers** `IsStealthed` / `IsMounted` / `UnitStandState` (`API.md:7574+`) —
+  back simple `[stealth]` / `[mounted]` / `[standing]` conditionals.
+
+---
+
+## Cross-cutting requirement
+
+Gate **every** ClassicAPI path behind feature-detection with graceful fallback,
+mirroring the nampower `HasMinimumVersion` pattern (`Conditionals.lua:227`):
+
+```lua
+if C_UnitAuras and C_UnitAuras.GetAuraDataBySpellName then
+    -- ClassicAPI path
+else
+    -- existing libdebuff/tooltip path
+end
+```
