TooltipExtraData

## [1.4.0] - 2026-04-24

### Fixed
- Fixed a critical Lua error:
- attempted to index a table that cannot be indexed with secret keys.
- Replaced unsafe GUID-based table indexing with a safe Name-Realm key.
- Fixed player item level (ilvl) disappearing from tooltips after inspect updates.
- Fixed flickering of player ilvl/spec caused by tooltip re-rendering and stale state tracking.

### Changed
- Reworked inspect cache system to use a safe and stable key instead of GUID values.
- Improved tooltip rendering logic to verify actual line presence instead of relying only on internal state flags.
- Adjusted inspect request flow to allow re-fetching data when cache is missing without causing spam.

### Performance
- Prevented inspect requests while in combat.
- Added per-unit inspect throttling to avoid repeated inspect calls.
- Reduced reliance on OnUpdate for inspect triggering.
- Increased inspect ticker interval to lower CPU usage.
- Optimized inspect queue processing to minimize unnecessary API calls.

### Stability
- Improved compatibility with Retail security restrictions related to “secret” values.
- Hardened tooltip update behavior during rapid mouseover changes.
- Improved consistency of player info display across delayed inspect callbacks and tooltip refreshes.
