Studio gap-close wave1 — all smokes pass lic check

Summary

packages/li-studio library and smoke tests compile under lic check on feat/studio-gap-close-wave1 (timeline extern, move semantics, MCP/viewport/loading contracts).

Agent continuation

  1. Read — packages/li-studio/src/lib.li; packages/li-studio/li-tests/manifest.toml; scripts/patch-studio-lib-final.py (regenerate lib from 532cf31 base if rebased).
  2. Run — ./build/compiler/lic/lic check packages/li-studio/src/lib.li; loop lic check packages/li-studio/li-tests/smoke/<name>.li.
  3. Then — merge PR after CI; continue PH-UX / PH-AGENT runtime wiring in runtime/li_rt.c if smokes need live MCP/timeline state.
  4. Blocked on — human merge; wgpu viewport failure probe (UX-08 still mock-only).

Changed

  • packages/li-studio/src/lib.li — li_rt_studio_timeline_* extern block; raises IO on timeline/viewport wrappers; inspector field row offsets without int×float; E0311 copy fixes in compose paths; studio_inspector_field_at ensures; MCP ensures result != ""; shell loading 6-arg + w0/h0/w1/h1; studio_compose_shell_profile layout borrow via lay.
  • packages/li-studio/li-tests/smoke/studio_profile_roundtrip.li — separate compose_chk / compose_paint (move semantics).
  • packages/li-studio/li-tests/smoke/studio_viewport_error.li — fresh layout/overlay/shell per check (move semantics).
  • packages/li-studio/li-tests/manifest.toml — studio_mcp_tools.li smoke entry (if missing).
  • scripts/patch-studio-lib-final.py — reproducible lib patch from git base 532cf31.

Not changed

  • runtime/li_rt.c behavior beyond existing symbols (no new MCP server).
  • packages/li-render, packages/li-gpu, compiler codegen.
  • Master plan PH phase ordering or benchmark thresholds.
  • SDL/wgpu windowed studio demo (headless smokes only).

Breaking

N/A — compile/proof contract fixes only; public API names unchanged.

Security

N/A — no CVE catalog or trusted.lean changes.

Performance

N/A — no benchmark row; compose/paint smoke compile only.

Downstream

N/A — li_std_studio_version() remains 5; consumers re-run lic check on studio imports after pull.
