  "result": "I rewrote `validator.py` to follow all 11 rules in `SCHEMA_RULES.md`. I haven't run any hidden or full-spec tests. I only ran two quick spot checks, and both gave the expected output:\n\n- **Escaping, `$ref` and error placement:** a schema with an escaped key (`a/b~c`), a `$defs` ref, a missing required name and a disallowed extra member. The errors came out at the right paths: `/a~1b~0c` for the type error and `/z` for the extra member.\n- **Equality and recursion:** `true` is not equal to `1` in `enum`/`uniqueItems`, and a recursive `$ref: \"#\"` schema terminates.\n\n`validate(schema, instance)`, the `{\"path\", \"keyword\"}` return format and `SchemaError` are unchanged. It uses only the standard library.\n\nChoices where the rules were silent:\n- **Unresolvable `$ref`:** `SchemaError` is raised only when validation reaches that `$ref`, not up front. Any form other than `\"#\"` or `\"#/$defs/<name>\"` counts as unresolvable.\n- **`$ref` cycles:** a schema like `{\"$ref\": \"#\"}` that loops back to the same location with the same instance is cut off and adds no errors. The code then doesn't recurse forever.\n- **Unknown `type` names:** they match nothing, so they produce a `type` error rather than raising.\n- **Non-schema values:** a subschema that is neither a dict nor a boolean raises `SchemaError`.",
