# Reproduce `waitcheck-lds-dispatch`

Sanitizer case `waitcheck-lds-dispatch` from run `2026-08-16-31946286609` 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: `b4be48fdd6dd7e12056a6141c93377feed9f1688`
- Date: 2026-08-16
- Target: `gfx950`
- Class: survey (observed-only, non-gating)
- Workflow run: https://github.com/ROCm/aorta/actions/runs/31946286609

## 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 b4be48fdd6dd7e12056a6141c93377feed9f1688
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/lds.hsaco -- a gfx code object built from fixtures/kernels/lds_reduce.hip: `export PATH="${ROCM_PATH:-${ROCM_HOME:-/opt/rocm}}/lib/llvm/bin:${PATH}"`; `mkdir -p recipes/sanitizers/fixtures/isa`; `hipcc --genco --offload-arch=gfx950 recipes/sanitizers/fixtures/kernels/lds_reduce.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/lds.hsaco; else cp tmp.o recipes/sanitizers/fixtures/isa/lds.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-lds-dispatch.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.
