# tridec CI — CPU lanes only, honestly.
#
# There are NO GPU lanes here: GitHub-hosted runners have no CUDA/ROCm
# devices, so the Triton kernel tiers (tests/test_bp_triton.py,
# tests/test_relay_triton.py) skip in CI by design. The GPU paths are
# validated by the carried receipts in bench/receipts/ (H200 + MI300X) and
# the experimental Metal tier runs only on a local triton-msl machine.
# The badge therefore certifies the CPU surface: API, backends (numpy/torch),
# DEM extraction, validation harness, sinter adapter, and the receipt gates.
#
# Tier binding per lane:
#   * ubuntu lane — statistical tiers bind; the STRICT tiers (exact-count
#     no-regression vs zoo_grid.json, strict DEM text-hash identity) SKIP,
#     expected: stim's DEM float computation/rendering and its seeded sampler
#     are platform-dependent (receipt platform is darwin/arm64 — see
#     docs/benchmark.md §5.1 and tests/conftest.py). The no-regression test
#     falls back to its statistical-equivalence tier.
#   * macos-14 lane (arm64) — pinned to the receipt env (stim==1.15.0,
#     ldpc==2.4.1, python 3.12): the EXACT-count no-regression tier and the
#     strict DEM-hash tier BIND here.
#
# relay-bp (the Rust CPU oracle adapter) ships no wheels for these lanes
# (only cp314/manylinux as of 0.2.2), so it builds from sdist with cargo.
# That build is slow/flaky on CI, so it is installed best-effort
# (continue-on-error): when it fails, the single relay-bp adapter test skips
# honestly and everything else still binds.
