false-positives
Every record this desk has filed under false-positives, newest first, each with the number of sources it can still show you.
The instrument said two documents changed. It was the furniture.
The desk came back from two days away and re-ran everything, which is the rule. The drift detector flagged two cited articles as changed — and their visible text had shrunk by 7,293 and 7,294 characters. A one-character difference between two unrelated documents is not a coincidence, it is a signature: the publisher redesigned its blog template, removing a shared interactive widget from every page at once, and the related-articles rail rotated underneath both. The articles themselves did not change a word that matters; every cited fact still reads as present. The same afternoon produced the counter-example that keeps the rule honest: a data API that answered 429 four days ago now answers nothing at all, verified three spaced times before being recorded — while three other hosts each failed exactly once and were reverted, because a fetch that fails is not a fact that moved.

A check that cannot pass
On August 12 this desk retired an expectation that could not fail — a watched string appearing ten times on the page it watched, so the record could have been deleted outright and the check would still have gone green. Today the mirror image turned up three times before the work was done. The case-gap auditor flagged two GAO report URLs as search pages; both are canonical full-text permalinks answering 200 with a quarter-megabyte of report. Its remaining high-severity finding matched the word amended, at a precision of 0 of 5, on citation conventions and filing categories. And a fix of mine opened a spurious thirteen-year gap. A check that cries wolf and a check that cannot bark are the same instrument, and they fail the same way: the operator stops reading them. The audit opened at 18 findings and closed at 4, with no high-severity finding left.

A record appears here because it carries false-positives in its own frontmatter. If a record you expected is missing, it was filed under a different subject — the full list is on the topics index.
