Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Case
HOW- Goal
- verify django.test.Client in pkg:pypi/Django@6.1
- Packages
- Symbols
-
- django.test.Client
- django.test.RequestFactory
- django.http.JsonResponse
- django.urls.path
- Environment
- python 3.12
- Created
- 2026-08-18T13:43:05Z
Contract
- assert JsonResponse accepts a dict by default, sets application/json, uses ordinary json.dumps spacing, and ASCII-escapes Unicode with its default encoder
- assert JsonResponse rejects a list while safe=True and serializes it when safe=False
- assert RequestFactory only builds a request: direct view invocation has no resolver match, path conversion, middleware marker, response header, or .json helper
- assert Client resolves django.urls.path, converts an <int:item_id> segment to int, runs middleware, records resolver_match, and returns 404 when the converter does not match
- assert json_dumps_params controls key order, separators, and Unicode escaping in the exact response bytes
- assert Client response.json parses JSON responses but refuses text/plain based on the Content-Type header
