BigCommerce follow-up: October 14, 2026 (.70, fresh scan)

Source: https://cornerstone-light-demo.mybigcommerce.com/all/chambray-towel/
Scan job ID prefix: 6efcb7653674
Scan time recorded in product.csv: 2026-10-14T14:54:28.579Z
Settings: Single Page, Recommended (two images), default ZIP and all verified versions ZIP.

RESULT
- Fresh default ZIP: 2 selected / 2 downloaded image files; no download-errors.csv.
- Fresh all-versions ZIP: 2 selected / 2 downloaded main files and nine page-version entries, no download-errors.csv.
- Both archives pass ZIP CRC checks and image decoding. Two main image files are byte-for-byte identical across exports.
- Original failed BigCommerce run remains 1/2; its failed-file retry recovered 0/2.
- First gallery image: the original failing main URL used /images/stencil/1280w/ and scan recorded 190,383 bytes. The later successful main URL used /images/stencil/960w/ and delivered 178,112 bytes, a 900x900 JPEG.
- The later successful main JPEG SHA-256 is the same as the 900x900 page version already present in the original all-versions ZIP. This is a newly selected URL, not a successful retry substitution.
- Second main image remains a 900x900 JPEG (67,701 bytes) with the same SHA-256 as the earlier successful file.
- The 500x500 page version that failed earlier now downloaded successfully.
- No failed-file retry was available or needed during the .70 fresh scan. This is NOT evidence that the new .70 verified-alternative fallback succeeded against a live failure.
- The standalone 409 asset request in the Windows server log referenced the original job 4ebe81f1..., whereas the fresh scan job used 6efcb765.... It therefore does not contradict the fresh ZIP result.
- The all-versions ZIP includes three extra byte-identical 900x900 page-version entries, so its nine extra entries are not nine distinct image contents.

SOURCE EVIDENCE
- image-details.csv / image-urls.txt: exported by the fresh scanner.
- default-image-hashes.csv / all-versions-image-hashes.csv: extracted from actual downloaded ZIP bytes.
- scan-screenshot.png and gallery-screenshot.png: supplied screenshots from the Windows test.
- No downloaded product photos are redistributed in this evidence archive.

SCOPE
One repeat scan of the same product URL on the same day, not platform-wide reliability testing. The source server response or scan-selected URL may differ on subsequent attempts. No assertion about the exact cause of the earlier mismatch.
