Every other job already passes persist-credentials: false. The MSRV job was the one still leaving the token in .git/config for the rest of the job, including while it builds and runs third-party code.
The macOS matrix does not define arch, so setup-python was always handed an empty architecture. Windows is the only job that varies it.
setup-uv keys on uv's host triple, the runner image and the Python patch version, so the 46 jobs shared 23 keys: Windows x86 with x64, 3.14 with 3.14t, every MSRV job with lint. One job per group saved and the rest restored a cache built for another interpreter, then skipped saving, so Windows x86 and the free-threaded jobs rebuilt gevent from source on every run. cache-suffix supplies what the key lacked, and setup-python now runs first so lint and MSRV stop keying on the runner's default Python. Prune before saving so 46 entries fit where 23 were already evicting within hours of the 10 GB limit.

Cache only source-built third-party wheels, with fallback restores across dependency changes. Share Linux/MSRV caches and separate Python ABIs and architectures.
Validated YAML/formatting and matrix keys. Cold and warm CI runs passed all 46 jobs; warm dependency installation time fell 42% from baseline.
