Year Catalogs

Operations below act on the year selected at the top right. The shipped catalog lives at data/<year>.json in the repo; admin edits are stored as a server-side override in the year_overrides table and take effect for every visitor immediately.

Upload a <year>.json from your computer. The file is validated, saved as a server-side override, and shown immediately to every visitor. Use this when you've prepared a new year's catalog (or pulled an updated one from the repo) and want it live without rebuilding the container.
Save the selected year's catalog — including any server-side edits or computed travel matrix — to your computer as <year>.json. Commit it to data/ in the repo to ship those edits to fresh deployments.
Geocode any trails missing coordinates via Nominatim (OpenStreetMap, throttled to 1 req/sec), then fetch the full trail-to-trail drive-time matrix from OSRM. Stored on the catalog as travelMatrixMin — once present, reordering trails in the planner auto-updates each "Travel Next" value. Typically run once when first publishing a year.
Discard the server-side override for the selected year and revert to the shipped data/<year>.json. Use this if a test edit went wrong — riders see the official catalog again on their next load.
Same as Revert to Shipped, but prompts you for a year number first. Useful when an override exists for a year that isn't currently selected, or for cleanup of years no longer in the shipped manifest.
