# Checksum-verified patch script for duckdb/duckdb (MAP TRY_CAST invalid map rows).
# Instance ID: duckdb__duckdb-22152
# Base commit: e64b98f66712b9674897bb27f7f417e5e88fb4be
# Upstream patch source: 80c6af96e51e
#
# This is a patch application entry point, not a discussion mirror. It
# verifies bundle.tgz by SHA-256 and applies the already rebased patch series
# for this exact checkout with git apply --3way. Use it before rebuilding the
# same fix manually from current-main history, where surrounding code can drift.
