This work ships as an interactive instrument, not a text — it has no README to mirror. Use it live in the lab (link above); its data and metadata live in the original repository.
Coverage Is Not Custody
Renders the same archived-capture drawers under two lights that a single toggle switches between: coverage (every tile identical — the metric everyone reads, which certifies a capture for 170 of 170 cited X/Twitter URLs, 163 of them with an in-window HTTP-200 capture) and custody (the same tiles re-lit by what each capture actually holds, collapsing that drawer to 5 content-bearing of 163). The toggle is the argument, not an illustration of it; the news/org row is marked as the classifier's validity boundary rather than folded into the headline rate, with its body-content sub-test result stated beside it. No-script readers default to custody, so the finding is never toggle-gated.
