LayoutFurniImageView and LayoutAvatarImageView both fired async image
generation (TextureUtils.generateImage / SDK resetFigure callback) and
wrote the result back through setImageElement / setAvatarUrl with only
an isMounted / isDisposed component-level guard. If props changed
twice in rapid succession the older request could resolve last and
overwrite the newer image with a stale one, visible on slow
connections or fast scroll over grids of unique items.
Each effect now captures `const requestId = ++requestIdRef.current`
and threads it into every async callback (TextureUtils.generateImage,
the SDK's resetFigure listener, the cache write). When a callback
fires it bails if `requestIdRef.current !== requestId` — only the
latest effect's callbacks make it past the gate. A stale ENDED for
the previous figure now leaves the cache and the rendered url
unchanged.
Moves both bugs from "Open" to "Recently fixed" in
docs/ARCHITECTURE.md.
IGetImageListener.imageReady(result: IImageResult) takes a single
IImageResult object (with .id, .data, .image), but three call sites in
the client still used the old 3-arg destructure '(id, texture, image)
=> ...'. The renderer's RoomEngine.ts already passes
'new ImageResult(...)' to the listener, so the runtime payload matches
the new contract; the old call-site shape just type-errored.
Migrated:
- LayoutPetImageView (pet thumbnail loader)
- LayoutRoomObjectImageView (furniture thumbnail loader)
- useFurniturePresentWidget (gift box image generator)
Also tightened imageFailed handlers from 'imageFailed: null' to a
proper no-op arrow — the interface requires a callback.
React 19 dropped the no-arg useRef overload — the type-only useRef<T>()
form (no initial value) is gone, every call must pass an initial value.
The codebase had 15 occurrences of useRef<HTMLDivElement>() (DOM ref
pattern) all flagged by tsgo as 'Expected 1 arguments, but got 0'.
Mechanical sweep to useRef<HTMLDivElement>(null) — no behavior change,
React still hands out a ref object with .current set to null at mount.
Net tsgo error count: 57 -> 42.
Run eslint --fix across src/ to clear ~1900 mechanical lint errors
surfaced by the @typescript-eslint v8 + react-hooks v7 + react-compiler
upgrade in the React 19 modernization PR.
Issues fixed automatically:
- brace-style (Allman): try/catch one-liners reformatted to multi-line
- indent: tab-vs-space and depth corrections
- semi: missing trailing semicolons
- no-trailing-spaces
No semantic changes. Remaining 701 errors are real-code issues
(set-state-in-effect, rules-of-hooks, no-unsafe-* type checks) that
need manual per-file review.
