# Native builds for the release targets; see
# .agents/notes/implemented/architecture/2026-07-10-single-file-executable-sdk-runtime-distribution.md.
# A full target run retains one SDK wheel and three runtime wheels; subset
# dispatch retains the SDK wheel and selected runtime wheels. Bare executables
# and source closures are test inputs. Run manually, label a PR `build-exe`
# (remove and reapply to rerun), or call it from the Python release workflow.
# Checkout uses the triggering ref, so dispatch needs no separate ref input.
