Checks whether a set of scheduled appointments can feasibly be served by available vehicles given travel durations, time windows, and appointment times.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability halowerk-laufwerk-appointment-readiness-check-ca99764e -d '<json body>'
```

Example prompt: I have 3 drivers with shifts from 8am to 6pm and 10 customer appointments each with fixed appointment times and 30-minute service windows — can you check whether the fleet can realistically reach all of them on time given this travel duration matrix?

## When to prefer this

Use this endpoint when you need to validate whether a pre-scheduled set of appointments is operationally feasible before committing to customers — particularly when you have fixed appointment times (not just time windows), a known travel duration matrix, and a bounded fleet. Prefer this over general VRP solvers when the schedule is already defined and you need a readiness/feasibility verdict rather than an optimized route plan.

## Known failure modes

- Invalid duration matrix dimensions not matching jobs+vehicles count
- Job appointment_s or window outside vehicle shift range
- Missing required fields (id, point, demand, service_s, window, appointment_s) in jobs
- Vehicle capacity exceeded by cumulative job demand
- Matrix contains nulls for required travel legs causing incomplete feasibility check
- Exceeding max items limits (20 jobs, 4 vehicles, 21x21 matrix)

## Output

A JSON response indicating whether the set of appointments is feasible given vehicle shifts, capacities, travel durations, and appointment time constraints — likely including per-job or aggregate readiness status, and potentially flagging which appointments are at risk or unreachable.
