Kōka turns deploys, jobs and faults into stations on an elevated railway — read top to bottom, departing on signal, held when the track isn't clear.
No dashboards full of equal tiles. The line is the model — you watch work move along it the way you watch a train approach the platform.
A green track releases the service onto the line; an amber node tells everyone it is moving right now. No silent rollouts.
When a batch hands off to a fanout, it shows as a teal transfer node — the handoff is a place on the map, not a hidden hop.
A held signal stops the line at the exact stop that failed, so the queue behind it is obvious and nothing departs into a fault.
The split-flap board is the same line, sorted as a schedule — destination, pier, and whether the signal is green.
Free for a single line. Add piers, transfer routes and signal levers as your mesh grows.
