Duty Vigil

A volunteer rescue or ambulance service runs on people giving their own
time, around the clock — and the one thing that quietly breaks it is a
shift nobody's actually covering, usually discovered only when a call
comes in and there's nobody there. Holding the whole week in one
coordinator's head, or scattered across a chat group, is often the actual
weak point in a service built to be reliable.

Duty Vigil keeps that week properly instead. Each day shows its shifts as
a short chain, every one either covered by a named volunteer or flagged
plainly as open. Claiming a shift that already has someone down for it is
refused outright, so the roster can never quietly show two people covering
the same slot. A dedicated view lists every uncovered shift across the
coming weeks, soonest first, so a coordinator always has a real, ordered
answer to "what needs covering right now." A separate read compares each
volunteer's own share of shifts against the group's average, surfacing a
genuine imbalance only once there's enough of a pattern logged to judge it
fairly.

Duty Vigil coordinates coverage. It has no emergency-dispatch function of
any kind, and makes no claim about response time or the service's own
reliability — it only tracks who's down for what. It also holds no money
anywhere in it: volunteers give time, and nothing here is paid, owed or
tracked as a stipend or allowance of any kind.

Everything stays on the phone it's used on. There is no account, no
sign-in, and no data of any kind sent anywhere.
