# Reproduce `waitcheck-tiny`

Sanitizer case `waitcheck-tiny` from run `2026-09-10T124939-34476548600` of the AORTA sanitizer nightly. This directory is the run area for that one case: its report, the sanitizer output the verdict came from, and the provenance below. Its logs, recipe copy and inputs were pruned for falling outside the nightly's log-retention window. See `index.html` for every file actually published here.

## Run

- Commit: `6a8c70da0addc997c2d7067a5ed28d043464d9b8`
- Date: 2026-09-10 12:49:39 UTC
- Target: `gfx950`
- Class: survey (observed-only, non-gating)
- Workflow run: https://github.com/ROCm/aorta/actions/runs/34476548600
- Container image: `rocm/pytorch:rocm10.0_ubuntu26.04_py3.14_pytorch_release_2.13.0@sha256:3174cb7061d94c427da96c0edef4adea28046fa3f3b2ff3948dc4e995665ff8c`

## Observed

- Verdict: `pass`
- Execution: `complete`
- Findings: 0

## Run it yourself

First, the checkout this run used:

```
git clone https://github.com/ROCm/aorta && cd aorta
git checkout 6a8c70da0addc997c2d7067a5ed28d043464d9b8
pip install -e .
```

Then rebuild the CI-built fixtures, which are not published here (see 'Artifacts not published' below). Run these from the repo root, the directory the clone above leaves you in:

- fixtures/isa/tiny.hsaco -- a gfx code object built from fixtures/kernels/tiny_vecadd.hip: `export PATH="$(python -c "from aorta.instrumentation.rocm_paths import resolve_rocm_roots; print(resolve_rocm_roots().llvm_bin_dir)"):${PATH}"`; `export LD_LIBRARY_PATH="${LD_LIBRARY_PATH:+${LD_LIBRARY_PATH}:}$(python -c "import os; from aorta.instrumentation.rocm_paths import resolve_rocm_roots as r; x = r(); print(os.pathsep.join(dict.fromkeys([str(x.core_lib_dir), str(x.lib_dir)])))")"`; `mkdir -p recipes/sanitizers/fixtures/isa`; `hipcc --genco --offload-arch=gfx950 recipes/sanitizers/fixtures/kernels/tiny_vecadd.hip -o tmp.o`; `if head -c 24 tmp.o | grep -qF __CLANG_OFFLOAD_BUNDLE__; then clang-offload-bundler --type=o --unbundle --input=tmp.o --targets=hipv4-amdgcn-amd-amdhsa--gfx950 --output=recipes/sanitizers/fixtures/isa/tiny.hsaco; else cp tmp.o recipes/sanitizers/fixtures/isa/tiny.hsaco; fi && rm -f tmp.o`. The conditional matters: --genco emits a raw code object on some ROCm builds and a clang-offload bundle on others, and the recorded digest is of the unbundled object.

The exact invocations the nightly used are in .github/workflows/sanitizers-nightly.yml.

Set `ROCJITSU_PREBUILT` (unpacked rocjitsu bundle supplying rj_waitcheck and the ConSan hook) before running.

Finally, the sweep itself:

```
aorta sweep run --recipe recipes/sanitizers/daily-waitcheck-tiny.yaml
```

## Artifacts not published

These are CI-built and too large to publish for every retained run. Rebuild them as above and check the digest matches.
