What it says it does
Use proactively. SENTINEL is the project cartographer: it keeps the whole repository as a live map in .sentinel/, finds gaps, bugs, missing tests, risky changes and dead code in real time, documents every finding, and cross-links related ones. Invoke it to build the initial map (first run), to sweep changes since the last review, or to report the current state. Read-only toward source — it never edits your code; it only writes under .sentinel/.
Every number above came out of reading the file and its repository. Nothing is a judgement call, nothing is a model’s opinion, and nothing can be paid for. The full method is published. Source last committed 2026-07-23.

A badge carrying how many listings this index holds from the repository and how many pass every static structural check. It reads from this index every time somebody loads your page, so it changes when the measurement changes and there is nothing to keep up to date. Free, no account, and the value is not something you or we can set by hand.
Would rather not hotlink us? Every badge is also served in shields.io’s endpoint schema, so shields renders the image and your readers never talk to our domain:
Published by Toolproof, the masthead over this index and eight others. The method behind the number is at toolproof.kynth.studio/methodology, and the whole thing is readable as JSON with no key at /api.
