[claude]

LGTM — routine Renovate lockfile update, no code changes.

What was reviewed: the poetry.lock diff for chart_data_extractor, confirming the split into two matplotlib entries (3.10.9 for python<3.13, 3.11.0 for python>=3.13) is consistent with matplotlib 3.11's raised minimum Python requirement, and that hashes/dependency metadata are internally consistent.

Extended reasoning...

Overview

Single-file change to chart_data_extractor/poetry.lock, adding a new matplotlib 3.11.0 lock entry (for python_version >= 3.13) alongside the existing 3.10.9 entry (now marked python_version < 3.13). This is an automated Renovate dependency bump; no application source code is touched.

Security risks

None. This only updates a plotting library's lockfile metadata (hashes, wheel URLs, markers, dependency version constraints). Matplotlib is used for chart generation in a sandboxed code interpreter context, not for auth, crypto, or handling sensitive data.

Level of scrutiny

Low. This is a mechanical, bot-generated lockfile update with no logic changes. The added entry's dependency list (contourpy, cycler, fonttools, kiwisolver, numpy, packaging, pillow, pyparsing, python-dateutil) matches the existing entry's shape, and the version-marker split correctly reflects matplotlib 3.11 raising its minimum supported Python to 3.11.
