Every track row polled GitHub once a minute, spending up to three API requests per branch per viewer without shared caching or rate-limit backoff.
Cache checks for five minutes and share in-flight requests across viewers. Slow background row polling to five minutes, cache failures briefly, and pause installation requests until GitHub's retry/reset deadline. Report rate limiting explicitly and invalidate cached checks after Switchyard opens a PR.
Validation: 10 GitHub checks regression tests pass, covering concurrent readers, expiry, installation isolation, reset recovery, and permission failures. Reports can be up to five minutes old; the cache and cooldown are scoped to the server process.
