# Python driver for the interop harness. Speaks the same neutral driver contract.
#
# Uses the project venv directly rather than `uv run`, for two reasons: uv would
# re-resolve the environment on every invocation, and the harness invokes this
# script many times (the health probe alone runs once per tier). The venv is
# created on first use, the way go.sh and rust.sh build their binaries on first
# use, so a cold build never happens inside a health probe -- a slow probe reads
# as an unavailable driver.
#
# On hosts without a cryptography wheel (FreeBSD, notably) that first `uv sync`
# compiles it from source and takes several minutes. Set BONEMESH_PY to an
# interpreter that already has `cryptography` installed to skip the venv entirely.
