#
# Linux gate — the enforcement point for invariant I5: "never deploy code that
# hasn't run on linux." Pushing to the HF Space deploys to prod and runs NO
# tests there, so this gate (wired as a pre-push hook) is the only check between
# a local change and production. It catches the class of bug that passes on Mac
# and broke prod: DuckDB struct/timestamp marshalling on the linux-x64 binding
# (R2) and the connection lifecycle (R5).
#
# Two legs:
#   (1) host vitest — unit/logic suite (fast; connection-reset + transforms).
#   (2) linux/amd64 DuckDB read-path smoke on the prod-pinned binding (the real
#       net for the Mac↔linux divergence).
#
# Requires Docker. Coverage grows: add parity / render-equivalence tests to the
# linux leg as they land (see scripts/linux-gate/README.md).
