 ## Separate observation for Steve (NOT a hero defect)
 The 404/410/403 resource errors suggest a dead app asset / broken third-party reference somewhere in the live theme — worth a theme-health look independently (own ticket), but out of scope for the banner work.

+## Sweep 2 — CONTRARIAN GATE + evidence (the verification sweep 1 skipped)
+Cody returned **FIX FIRST**, correctly flagging that sweep 1 *asserted* "third-party" without tracing URLs (the `presence-check false-clean` anti-pattern). Re-ran with a network+DOM trace. Every hypothesis reproduced-and-**disproven**:
+
+| Cody hypothesis | Evidence | Verdict |
+|---|---|---|
+| A hero tile/collection.image URL 404s | All **4 mosaic tiles loaded** (xja-47017, xjc-47054/56/57); **none** in the failed-request list | DISPROVEN |
+| Product grid broken (empty-JSON = grid fetch fail) | **459 grid items rendered**; grid+filters+sort visible in screenshot | DISPROVEN |
+| Mosaic visual unverified | Screenshot: sharp 2×2 of 4 distinct textures, scrim title legible | CONFIRMED GOOD |
+| Errors are actually the hero's | Traced by URL: `403 shop.app/pay` (Shop Pay), `410 paypal.com/tagmanager` (PayPal), `404 /collections/vendors.json` (Boost/theme fetch) — **zero hero-origin** | DISPROVEN |
+
+**Empty-JSON pageerror root cause:** a Boost/theme fetch of `/collections/vendors.json` → 404 (empty body) → `.json()` throws. Non-fatal (grid still loads 459). NOT the hero.
+
+## FINAL VERDICT: BUILD CLEAN (now proven, not asserted)
+The hero deliverable passes every layer AND the trace confirms zero failing requests originate from it. Reds are all external platform/app noise.
+
+### Residuals (honest, both pre-existing & out of hero scope)
+1. **B5 Safari / B6 Firefox skipped** — engines not installed = a real cross-browser coverage gap. The only hero compat risk is the `:has()` <4-tile mosaic degrade (supported Safari 15.4+/Firefox 121+; affects only rare sub-4-product collections). Not proven broken; acknowledged untested.
+2. **`/collections/vendors.json` 404** — a theme/Boost fetch to a dead endpoint (source of the empty-JSON error). Pre-existing, unrelated to the banner; worth a separate theme-health ticket.
