+# Published reports
+
+This branch is written by CI only; don't push to it by hand. It holds the
+latest reports of `main`, which the Observatory reads:
+
+- `cli.size.json`: byte and gzip size of the release `comline` binary.
+- `cli.coverage.json`: line and function coverage per crate.
+- `cli.compile.json`: a clean release build's seconds per crate.
+
+All three come from `.github/workflows/reports.yml` on every push to `main`;
+the formats are the Observatory's `DATA.md` (`size`, `coverage`, `compile`).
+Each report names the `main` commit it measured. Every publish is one commit
+here, so `git log -- cli.size.json` is the series.
