an explicitly documented local-development exception if necessary. Update the

- Line 23: Update the BINARY_MATCH_CHUNK_SIZE initialization to parse the
environment value safely with a fallback, and require the resulting chunk size
to be greater than zero before using it. Preserve the default behavior for
missing or invalid values so module import and chunk iteration cannot fail or
skip matching.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Catch response-processing errors per chunk.
The try still wraps the entire loop (Lines 192-206). A malformed successful response—for example, a JSON array causing response.get(...) to raise—exits the loop and skips every later chunk. Move the try inside the loop so this failure follows the stated “continue with next chunks” behavior.

Keep separate /binary/match entries when checksum is empty or "0" so same-basename binaries are not given identical OSS attribution.
Omit /binary/match payload entries that have empty/"0" checksum and tlsh, since there is nothing useful to match against.

Theresponse is Nonepath now correctlycontinues, but an exception raised while processing a successful response (e.g.,response.get("results", [])on a malformed payload) propagates out of the loop into the outerexcept, terminating iteration — every chunk after the failing one is silently skipped rather than attempted.
