info ~~warn~~ → info by review encoding-base64 tests/test_json.py:193:22

base64-like blob (44 bytes, compression ratio 1.25) (raw pass, confidence 0.60)
```
    data = b'\xd8\x07\xc1Tx$\x91F%\xf3\xf3I\xca\xd8@\x0c\xee\xc3\xab\xff\x7f\xd3\xcd\xcd\xf9\xc2\x10\xe4\xa1\xb01e'
    encoded_std = b'"2AfBVHgkkUYl8/NJythADO7Dq/9/083N+cIQ5KGwMWU="'
    encoded_url = b'"2AfBVHgkkUYl8_NJythADO7Dq_9_083N-cIQ5KGwMWU="'
    assert to_json(data, bytes_mode='base64') == encoded_url
```
dismissed LLM, confidence 0.97 Test fixture containing expected base64 encodings used to verify bytes serialization in a JSON library.
Reasoning
The flagged blob is a base64 literal in a unit test that checks to_json base64 encoding of a 32-byte binary sample against expected standard and URL-safe outputs. The raw pass flags any base64-like string, and this is a deliberate test fixture in a JSON library, not obfuscated or malicious code. It has no execution or network behaviour.

Reproduce This Scan

Run disclude locally to verify. These commands scan the published file; the "new in this release" marks come from comparing it with the previous release's file, which they don't repeat. Add --format sarif for SARIF output. Add --llm (with an API key in the environment) to include the LLM review.
