+// Mechanical check for .github/ISSUE_TEMPLATE/*.yaml.
+//
+// Fail-closed by design: anything the checker cannot statically resolve is reported as an error
+// asking a human to extend the check, never passed through. A silently-broken issue form is
+// invisible in review — GitHub simply refuses to render it, or drops a prefilled value, and
+// nobody notices until a user hits it.
+//
+// Checks:
+//   1. Every template parses as YAML and satisfies GitHub's issue-form schema: known top-level
+//      keys, `name`/`description`/`body` present, known element types, unique non-empty ids,
+//      `markdown` blocks carry neither id nor validations, dropdown/checkboxes have options,
+//      and checkboxes use per-option `required` rather than `validations.required`.
+//   2. zh/en parity — templates pair by numeric prefix (0N ↔ 1N). The pair must expose the same
+//      element sequence (type, id, required, render, multiple) and the same title/type/labels,
+//      so a field added to one language cannot silently go missing in the other.
+//   3. The `issues/new?...` prefill contract. GitHub prefills an issue form from query params
+//      keyed by *field id*, so renaming or dropping an id silently breaks every link that used
+//      it — including links baked into already-installed extension builds, which keep sending
+//      the old param forever. Every such URL built in src/ is parsed from the TypeScript AST
+//      (not string-matched) and each of its params must resolve to a real id in every template
+//      the URL can select.
+//
+// Run with `--root=<path>` to check a tree other than this file's repo checkout.
