Automated Dependabot Review — APPROVED ✅

Step 1: Code Review

Changes: Only uv.lock was modified (1 file, +3/-17). The lock resolves python-multipart from 0.0.28 → 0.0.31 with updated sdist/wheel hashes; platform wheels for cffi/cryptography are pruned consistently with this workspace's platform set.

Consistency: The description correctly lists the three releases (0.0.29, 0.0.30, 0.0.31) between the old and new versions. Lock hashes match the published python-multipart 0.0.31 wheel on PyPI. ✓

Correctness:

• 0.0.29: Handle malformed RFC 2231 continuations — purely defensive/correctness fix.
• 0.0.30: Parse application/x-www-form-urlencoded per the WHATWG URL standard (only & as separator, not ;). This is a behavioral tightening but aligns with the spec; any reliance on ; as a separator was non-conformant. Ignoring RFC 2231 extended name*/filename* parameters keeps the plain parameter authoritative per RFC 7578 §4.2.
• 0.0.31: Security hardening — bounds header field name size before validation (prevents resource exhaustion), validates Content-Length is non-negative in parse_form. These are defensive improvements with no user-visible regression risk.

python-multipart is a transitive dependency pulled in through dikw-core; the plugin layer does not call it directly, so the behavioural change in 0.0.30 does not affect plugin code. ✓

Security: This is a Dependabot security advisory PR. The 0.0.31 hardening (bounded header field name size, non-negative Content-Length check) closes potential DoS/resource exhaustion vectors in multipart parsing. Merging is recommended from a security standpoint. ✓

Test coverage: No functional code changes in this repository; the update is entirely in the lock file. ✓

Step 2: Regression Verification

CI ran the full test matrix on this branch.

Step 3: CI Results — PASSED ✅

Check	Result
test (3.12)	✅ success
test (3.13)	✅ success
analyze	✅ success
CodeQL	✅ success

Step 4: Merging

All steps passed. Squash-merging now.
