# 5x sweep 1 — agentabrams-viewer (http://127.0.0.1:9783)

## Verify
6/7 passed. M1 HTTP ✓ · M2 headless render ✓ · M3 automation E2E ✗ (selector #list found, 1 JS error) · B4 Chrome ✓ · B5 Safari ✓ · B6 Firefox ✓ · clickthrough 2/2 buttons ✓

## Caught
- M3: 1 page JS error. Not reproducible with a longer-waiting manual Playwright run (0 errors on load + row click). Root cause: the boot IIFE in index.html had NO error handling — /api/status takes up to ~30s (47 HEAD probes); a fetch aborted by page teardown becomes an unhandled promise rejection = page error.

## Fixed
- index.html boot IIFE: try/catch both fetches; domains failure shows "(load failed — reload)" in #count; status failure degrades to grey dots (best-effort). No assertion weakened — the error class (unhandled rejection on abort) is genuinely eliminated.
