+recorded as `skipped` and still rolls up green, so a commit status on
+`next` does not by itself evidence an executed check (#152). Before
+#119, a warm layer cache also let the gate report success without
+executing anything, and replayed the previous build's console log so
+the lie looked like a real run. Note: `TODO.md` was deliberately
+deleted from this repo in f9a9569 (2026-03-01, #6); its content was
+folded into the README TODO section, which this draft reconstructs as
