How it actually arrives

An 8-K's meaning is in its item number, not its text. These are the items the filings containing this phrase were filed under. The first group is something that happened to the company. The second is the phrase turning up in the ordinary course of reporting, most often in an earnings release, which is a very different thing and is usually the larger number.

This is why a headline count on its own overstates the case. Where the routine number dominates, the phrase is being tracked as language rather than as events.

What it obligates

Our corpus holds 32 controls across 21 frameworks whose text speaks to this. Not a judgement: these controls say so, and each is one lookup from its source document. Ordered by how much each framework has to say about it, so the one that will cost you the most work is first. Every name opens that framework in the corpus.

What an auditor will ask you to produce

The artefacts named on those controls, most frequently cited first.

How it usually fails

Recorded when each control was verified against its source. This is where programmes that think they are covered turn out not to be.

Where this comes from

The left half is public record: SEC full-text search over 8-K filings, counted across a 7 day window against the equivalent window before it. You can check every row.

The right half is ours: 723 frameworks and 20,473 controls, 531 of those frameworks verified against their source documents, with the auditor evidence and common failure modes recorded control by control. Controls appear here because their own text names this term.
