Agent repair and background progress verification — 2026-07-30

The Windows production renderer was built with the repository's exact headless command and launched from out/main.js on the off-screen Win32 desktop desktop-material-agent-repair-20260730. All interaction and capture used the fixed Lowlevel MCP endpoint; the visible desktop was never focused or touched.

Accepted surfaces

Command palette filtered to the new Codex/OpenCode and Cheap LFS actions

The palette retains the fuzzy/substring/regex mode, case toggle, full regex builder, and appearance control. Codex finds both repair actions and the Cheap LFS progress command. Pressing Enter on Fix CI with Codex/OpenCode opened the real provider composer directly:

Bounded failed-CI repair request in the real provider composer

The Build & Run panel rendered an elapsed clock, estimated finish, determinate progress, and an enabled close button while installation was active:

Active Build & Run task with elapsed and ETA progress

Closing the panel did not invoke Stop. Selecting Show background progress in the command palette reopened the same output. The test repository's install then failed independently of this UI change, and the reopened panel truthfully showed that terminal state:

Reopened background output after direct command-palette activation

Cheap LFS collapse/expand was verified in the focused DOM suite rather than by inventing an active transfer: the header remains visible, aria-expanded and aria-controls change correctly, and the detailed progress container toggles its hidden state.

Automated evidence

TypeScript: yarn tsc --noEmit passed.
Focused Windows tests: 42/42 passed across six files.
Targeted source lint passed after replacing the ARIA id's rejected Math.random() with a deterministic per-mount counter.
Repository-wide Prettier check passed.
Headless desktop and the exact launched Electron PID were closed after capture.
