Pull request overview
Updates the repository’s CI workflows to explicitly separate cache-producing jobs from cache-consuming/verification jobs, aiming to enforce cache read/write behavior at the GitHub Actions platform level during e2e and benchmark runs.
Changes:
- Add job-level cache-mode: write-only to cache producer jobs so they always seed fresh entries without restoring.
- Add job-level cache-mode: read to restore/verification jobs so cache writes are blocked by platform enforcement.
- Split the benchmark workflow into a warm-caches (write-only) phase and a benchmark (read) phase to measure seeded restores only.
| File | Description |
|---|---|
| .github/workflows/e2e-cache.yml | Applies job-level cache access modes across the cache e2e matrix to distinguish producers vs consumers. |
| .github/workflows/benchmark-cache-restore.yml | Constrains warmup to cache writes and benchmarking to cache reads to isolate restore performance measurement. |
