-| Widescreen | Currently **stretched 4:3**, not native — README discloses this | The big one. `WIDESCREEN-FOV-PLAN.md` Option B / CenterHUD path; needs the G-class sign-off decision (CenterHUD touches game code). |
+| Widescreen | Currently **stretched 4:3**, not native — README discloses this | **DONE 2026-09-23 (D334 world `d5d9a36a`, D335 HUD/front end `f62bceaf`)**: native at any aspect, default on, F10 toggle; Rule-2 approved. Owed: user HUD playtest at 16:9/21:9; D335a cosmetic. |
 | D237 | F10 overlay: mouse-wheel scroll, more settings, category grouping | Pure port-layer; wheel event already reaches the port. |
 | D314/D315 | F10 flicker (user-deprioritized) + main-vs-in-game menu scaling | D315 deferred from v0.3.0; bigger design question — lands naturally with the overlay work. |
 | D238 | Mouse sensitivity rework (master sens, RMB aim sens, Y-gain parity) | D304 already merged hipfire+F10 into one control; remainder is feel tuning in `input.c`. |
