Two failures, two causes.
GitHub-hosted jobs never started: 'recent account payments have failed or
your spending limit needs to be increased'. Not a config problem. Public
repos get hosted runners free, so this may resolve itself; meanwhile every
job runs on spark-1, which is also the deployment architecture (Oracle
Ampere A1 is aarch64), so this is an improvement rather than a workaround.
The aarch64 job failed with exit 127 — cargo not found — and kept failing
after each fix. Cause: Swatinem/rust-cache's post-step prunes ~/.cargo.
That is correct on a GitHub-hosted runner where ~/.cargo is disposable, and
destructive on a self-hosted one where it is the real toolchain. It deleted
~/.cargo/bin/rustup after the first successful run, leaving every shim a
dangling symlink. The action is removed and the toolchain moved to
/opt/rust, wired through the runner's .env and .path, so it is out of reach
even if someone re-adds it. Caching bought nothing here anyway — the runner
keeps its target dir between runs.
