-Closed gates are a showstopper. Status sits before Play. The pack is polled three times a day at 08:00, 14:00, and 20:00 Asia/Kolkata. A Cloudflare Worker (`workers/status-ping`, cron `30 2,8,14 * * *` UTC) `POST`s GitHub `workflow_dispatch` for `.github/workflows/status-bake.yml`, because Actions `schedule` never registered on this repository. The bake itself still runs in Actions: `build_status.py`, then a pull request when `status.json` or `status-history.json` changed, then merge through `check`. Each bake also unions that day’s closed stations into `data/en/status-history.json` and refreshes the corporate service-update notice when it changed. The only Worker allowed is this status ping. There is no R2, KV, D1, Pages Function, or app-facing Worker. Closed means no board and no alight. Trains still pass. Transfer is true only when a note says the interchange facility is available. A “will not be available” interchange note, or a silent closed station, blocks a change. Status names one nearest open station, not a list of gates. Plan keeps Least and Fewest for the asked pair and offers Alternative via that one open substitute. Location is requested only after “Use my location.” Coordinates are not stored.
