No job timeout · Test React Canary
No job sets `timeout-minutes`, so a hung step can run to GitHub's 6-hour default. Add `timeout-minutes` to each job.
jobs:
build:
runs-on: ubuntu-latest
timeout-minutes: 15Scheduled at the top of the hour · Test React Canary
The schedule fires at minute :00, GitHub's peak window, where scheduled runs get delayed or skipped. Shift to any other minute for the same cadence with less contention.
on:
schedule:
- cron: '19 0 * * *' # was '0 0 * * *' — any non-:00 minute avoids the herdScheduled workflow runs in forks · Test React Canary
The schedule has no repository guard, so forks that enable Actions inherit the cron and burn their own minutes. Gate the job with `if: github.repository == 'owner/repo'`.

nightly:
if: github.repository == 'owner/repo'

`upload-artifact` has no `retention-days`, so artifacts keep up to 90 days (storage cost). Set e.g. `retention-days: 7`.
