name: Python SDK conformance and cross-impl determinism

# The `atrib` Python distribution (python/) is not a pnpm workspace member,
# so ci.yml's `pnpm -r test` never reaches it. This workflow runs the
# Python conformance suites, mypy strict, and the cross-implementation
# determinism judge (python/tests/cross_impl/), which drives the built
# @atrib/sdk through packages/sdk/scripts/cross-impl-vectors.mjs and
# byte-compares records/hashes/tokens across the two implementations
# (D136). Path-scoped to the byte-identity surface.
