The bounded patcher could only ever fix defects whose failure output names
the source file. A pytest assertion that fails inside a test names only the
test: on ariadne build 404 the defective file appeared zero times in the whole
174KB console, and candidate selection returned ariadne/app.py, the wrong
file entirely.
Admit test files as readable candidates and follow their absolute imports back
to the module they exercise. Reading widens; writing does not. The patch
validator gates on allowed_path_prefixes alone, so a test file can now be read
for context and still never be patched - which also stops the classic bad fix
of silencing a failing test instead of repairing the code.
