# Scope: gates for the Python bindings (geographdb-py/). This workflow is
# entirely independent of the Rust crate's Validate workflow.
#
# Path filter: the job only runs when files that could affect the Python
# bindings change. A Rust-only PR (touching src/ or the CLI)
# does NOT trigger this workflow, so it cannot break Rust-only CI.
#
# Security review:
#   Only trusted inputs (paths and branches from `on:` config) are referenced.
#   No untrusted user-supplied fields are interpolated into run: blocks.
