The project picker could permanently settle on the generic folder when its first project.icon answer was empty while the host capability was still warming. Empty answers now stay uncached, so reopening the project picker asks again and displays the returned project favicon or language mark in both project menu rows and the current project trigger in the composer/new-tab location chip.

Leo described the current regression as: “project icons are CURRENTLY generic rather than the reading heuristics thing we did before”. The existing project.icon heuristic remains the source of truth; this fix only prevents an empty first answer from masking it and ensures the current chip uses the same badge as the menu. Remote projects still avoid local icon reads.

Validation

• git diff --check
• Added ProjectBadge regression coverage for an empty answer followed by a real icon.
• Browser/unit execution is pending the checkout’s missing @base-ui/utils/useIsoLayoutEffect dependency.

Changelog

Fixed project picker rows and composer project chips so a later project icon answer replaces the generic folder.

web / react-apps-check (1): (fail) a pooled Settings page claimed by the host reports its paint once its first screen is in [1100.30ms]

Not re-run automatically: web / react-apps-check (1), web / react-apps-check are not machine failures.

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's; yours means the failing file is one this PR changes, also red on main that main's latest full suite fails the same way, seen on other PRs that it failed on another pull request's run lately.

red: cmux-next checks (god files, concurrency, crash safety, l10n); no finished base run on be5d73b to compare; do not merge until green; see lane-rules
red: web / Web status; no finished base run on be5d73b to compare; do not merge until green; see lane-rules

Tour of c63216bbbf (run): no media. The tour did not run: only webview code changed (12 path(s)), which the gallery advisory run checks in Linux Chromium on the pull request (its artifact holds any captures); add the media-tour-mac label, then re-add media-tour, to tour it on a Mac.
