What do the raw wpt.fyi report.json records say for the WebVTT vertical-text and ruby reftests at WPT 5d23b743bb487d18c51ea0f016b4b22c0895a813, and can a failure message tell you what is wrong with the rendering?

Partially verified: the curator re-read none of the cited sources; S11, S12, S13, S14, S15, S16 rest on the producer's pinned reading. Across the four engines at WPT 5d23b743, the six WebVTT vertical-text and ruby reftest files give 24 results with exactly one pass (Firefox, bidi_ruby.html); all five vertical-text reftests fail everywhere. Curator qualifications: Partially verified: the curator re-read none of the cited sources; S11, S12, S13, S14, S15, S16 rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S11: HTTP 200, bytes equal to the producer pin; S12: HTTP 200, bytes differ from the producer pin; S13: HTTP 200, bytes differ from the producer pin; S14: HTTP 200, bytes differ from the producer pin; S15: HTTP 200, bytes differ from the producer pin; S16: HTTP 200, bytes differ from the producer pin. Third-party CI result summaries parsed 2026-10-22; no browser run; screenshots not inspected. Failure-message contents (screenshot hashes; Firefox pixel-difference counts 1444-2064) and expected-status metadata come from full wptrunner reports not held by the curator (F1-F3). Limitations: Third-party CI result summaries parsed 2026-10-22; no browser run; screenshots not inspected. Evidence status: curator/producer inference or synthesis from the cited sources (code read, not executed, where code is cited); correlated desk review (Claude); not independently reviewed.
