Module coverage_html 

A static HTML report: one file, no network, no service.

The point of this report is not a percentage – the CLI already prints that. It is to let a person trace a missing obligation to the line that carries it, offline, from a CI artifact they downloaded.

It is a single self-contained document on purpose. A copied artifact works with no server and no network; there is nothing to fetch from a CDN; and because a source file’s path is never used as an output path, a filename carrying ../ cannot write anywhere.

Four states are kept distinct, because collapsing them into one red/green score is how a report starts lying: uncovered (measured, nothing reached it), not applicable (nothing eligible), unmeasured (Supercov declined the obligation) and stale (the run no longer matches the checkout).

Functions

html

Render the report. sources carries file text only when it was verified to match the run; a file absent from it is shown by line number instead of annotated against source that may have moved.
