## What
Full RFC §4 cleanup on top of the ephemeral containerized-runner
migration. The runner image bakes tilelang + the runtime/dev stack, so
CI stops building/copying per-run venvs and installs only tileops
(`--no-deps`) via `scripts/ci/install_tileops.sh`.
- **gpu-smoke**: drop `Set up Python`, `Resolve runtime state` (venv
hash/copy/mtime-sync/divergence guard), `Cleanup isolated fork state`;
install via `install_tileops.sh`; run with the image's `python3`;
trust-route PRs by collaborator permission (write/maintain/admin →
resident `nightly` pool; everyone else + lookup failure → `fork` pool,
fail-closed); reclaim the `/ci-cache` layout (no wheels, no tool-cache
prune); per-test `--timeout` + a `timeout-minutes` backstop so a wedged
kernel cannot hold the single runner.
- **nightly**: `setup_nightly_venv.sh` → `install_tileops.sh`; system
`python3`; cache env `/data7` → `/ci-cache`; per-test timeout on the
pytest runs.
- **runner-maintenance**: drop the retired `venv` runs-on label (→
`nightly`).
- **preflight**: pin CPU installs with `constraints.txt`.
- **pyproject / constraints**: tilelang as a compatibility range
(constraints pins its deps, not tilelang itself); pin `pytest-timeout`.
- **reclaim action + verify script**: `/ci-cache` layout, drop
`WHEEL_DIR`; trim stamp on the persistent cache.
- **delete**: `setup_nightly_venv.sh`, `ci_venv_hash.py` and their
obsolete tests.
## In scope vs follow-up
To keep CI dispatching, installing and importing cleanly on the new
stack, this PR DOES adapt the import surface: `gqa_fwd_fp8` guards its
`from tvm import tir` with a sentinel that raises a targeted error only
when the kernel is built, and the fp8-GQA / topk-selector
kernel-building smoke cases are skipped via a `tvm.tir` availability
gate (with a focused test for the gate). So **CI is green at import**,
not red.
**Out of scope (follow-up):** the actual kernel migration off `tvm.tir`
(`tir.call_extern` → `tilelang.language` `T.*`) and any other new-stack
kernel regressions surfaced by gpu-smoke (e.g. a build hang in
`FP8LightingIndexerKernel`). Those are tracked separately; until they
land, the corresponding smoke cases are skipped or fail on the per-test
timeout rather than wedging the runner.
