+## T50g Acceptance
+
+| Asked | Done | Proof |
+|---|---|---|
+| Can a canvas or render surface be real on GPUI? | Yes, through `RenderImage`; nothing shares GPUI's device | gpui at 1a28cff: `paint_image`, `paint_surface` (NV12, Metal alone), no device hook; T50a review |
+| List what can be added | Every draft entry judged above: build, alias, host or blocked | this file; PRD chapter 44 |
+| Scope the owner chose | `RenderSurface` alone, chapter 44 | owner's answer, 2026-10-04 |
+| Linux, macOS, Windows, arm64 and x86_64 | Lib tests pass on all six; the gallery builds on five and passes clippy on macOS arm64 | CI run 37177191793 on b85955a |
+| Gallery example | Rendering page, its story in `stories.json` | ran on Linux: 720x360 in 22 ms, debug |
+| WebAssembly on the website | The story runs live from the wasm gallery | headless shots light and dark; `e2e/live.spec.ts` fails when the surface never redraws |
+| Docs | Rendering guide, `docs_render` compiled by `check.sh` | `e2e/docs.spec.ts` 24 passed |
+| Reviews | Each item in a herdr pane, codex `gpt-6.1-sol` at `max` | `tasks/reviews.md` |
+| Files at or under 500 lines | Largest new file 138 lines | `check.sh` |
+| Not done | Site not deployed; section notes clip at the frame's right edge on every story | owner's call; seen on MapView too |
