Review Comment:
Fixed in 49b2e0a2012eedef0a5b3ad40aa3c8d3ec9c45ea. Guarded compile row-limit
conversion against TypeError, ValueError and OverflowError, and use the bounded
10-row fallback for malformed/nonpositive values while preserving valid small
limits. Parametrized persisted-value regression tests fail before the fix and
pass after it.
Validation: chart unit suite 2604 passed, 3 skipped; pre-commit on changed
files passed, including mypy and pylint.
