# /5x REPORT — agentabrams-viewer (http://127.0.0.1:9783)
2026-07-22 · 4 sweeps · stop: clean-twice

| sweep | passed | caught | fixed | commit |
|-------|--------|--------|-------|--------|
| 1 | 6/7 | 1 (M3: 1 JS error) | boot IIFE fetch error-handling (correct hardening, wrong root cause) | b807e6b |
| 2 | 6/7 | same M3 error — no-progress guard fired; exact repro w/ system Chrome pinned it: /favicon.ico 404 (3x's favicon filter matches error TEXT only) | data-URI SVG favicon in <head> | 15161bc |
| 3 | 7/7 | 0 | — | — |
| 4 | 7/7 | 0 | — | — |

## Final six-way state
M1 HTTP contract ✓ · M2 headless render ✓ · M3 Playwright E2E ✓ (#list found, 0 JS errors) · B4 Chrome ✓ · B5 Safari ✓ · B6 Firefox ✓ · click-through: Reload + New Tab ✓ (10 skips are other-app selectors in the generic clickthrough, not defects)

## Also fixed this session (pre-5x, same repo)
- SSO cookie mis-scoping in the /site/ proxy (fleet-wide Domain= cookies now Path=/site/, Secure stripped for http loopback) — 8ef170b. This is what made clicking SSO-gated sites (builds.agentabrams.com) render instead of silently redirect-looping.

## Open items
None in this app. Note for the 3x runner (separate skill, not this repo): its favicon filter checks error text only — a missing favicon on ANY app under test will fail M3; consider filtering by m.location() too.
