Release notes: 2026-05-25 — studio-ux08-viewport-error-lib

Status: Ready for review
Repo: li-langverse/lic
Branch: feat/studio-gap-close-wave1
PH / REQ: PH-UX, UX-08
Author: agent

Summary (one sentence)

Wires UX-08 viewport error recovery into packages/li-studio/src/lib.li (compose overlay, shell chrome counts, paint path) matching existing li_rt_studio_viewport_error_* runtime and studio_viewport_error.li smoke.

Agent continuation (required)

  1. Read: packages/li-studio/src/lib.li (UX-08 section), packages/li-studio/li-tests/smoke/studio_viewport_error.li.
  2. Run: lic check packages/li-studio/src/lib.li; lic check packages/li-studio/li-tests/smoke/studio_viewport_error.li.
  3. Then: SDL/native host should map key events to InputState (UX-09); optional deploy/studio-demo/native/ input bridge when A+B+C are closed on branch.
  4. Blocked on: wgpu surface failure probe — none for mock IR merge.

Changed (specific)

Area What Evidence
packages/li-studio/src/lib.li studio_err_gpu, StudioViewportErrorOverlay, studio_compose_viewport_error_overlay, studio_paint_viewport_error, studio_shell_viewport_cmds + 6-arg studio_shell_chrome_count_palette studio_viewport_error.li
runtime/li_rt.c (already on branch) mock kind/retry li_rt_studio_viewport_error_*

Not changed (scope fence)

  • PH-GD-1 outliner — already on branch; not modified in this commit.
  • packages/li-world — already on branch; not modified.
  • SDL InputState ingest — not in this commit (see UX-09 release note).
  • wgpu / asset loader failure detection — not wired.

Breaking / Security / Performance / Downstream

  • Breaking: N/A — completes documented UX-08 API on StudioShellCompose.
  • Security: N/A — mock error kind only.
  • Performance: N/A — O(1) overlay rects.
  • Downstream: Hosts using 5-arg studio_shell_chrome_count_palette must pass viewport_error_kind.
