+# Pinned JSON Schema Test Suite
+
+This directory vendors the **complete** `tests/draft2020-12/` tree and the
+suite's `remotes/` fixtures from
+[JSON-Schema-Test-Suite](https://github.com/json-schema-org/JSON-Schema-Test-Suite)
+commit `80c87e8fca8b207a7a7ae944b875f0fcf889f46a` (MIT; see `LICENSE`).
+The GitHub archive SHA-256 is
+`eb54db8df07ddbfae5a1de447d97ba38377e1ccf5d96f2bf32b159af29a0b9d2`.
+
+The fixtures mirror upstream, except four trailing-space lines were normalized
+for diff hygiene. They are intended for fully offline validation: URLs under
+`http://localhost:1234/` identify files in
+`remotes/` and must never trigger network fetches. The historical selected
+subset in `../json_schema_import/` remains a separate regression corpus.
+
+Do not count the presence of these files as a conformance pass. The conformance
+tests exercise every required group, plus the optional format-assertion groups
+in their correct modes, without silent skips. Other optional groups are not
+claimed as complete.
