# Accessibility and medical-logistics feasibility

## Mobility chain

- Airline/aircraft: equipment dimensions, weight, battery rules, charger voltage/adapter, advance assistance, curb/check-in/security/gate/boarding/arrival handoffs, boarding and seat-transfer method, damage reporting, and repair fallback.
- Ground transport: ramp/lift capacity, clear width, occupant-in-chair securement, transfer assumptions, luggage/family capacity, and backup provider.
- Hotel: continuous step-free entrance, door and lift clearances, room/bath turning space, shower/toilet/bed fit, equipment charging, and verified refrigerator type when needed.
- Public realm: gradients, surface and cobble quality, curb cuts, pinch points, lift/funicular dependencies, outage fallback, accessible-route time, toilets, rest, and charging.
- Attraction/tour: continuous route, doors/lifts, toilet, companion policy, vehicle transfers, evacuation caveat, and direct confirmation status.

## Dietary chain

Core recommendations require direct evidence of cross-contact controls appropriate to the stated need: preparation area, fryer, utensils, shared flour environment, staff protocol, and fallback food. Menu labels and reviews are discovery leads. Supply a concise verification script the traveler can send; do not contact venues without authorization.

## Medication chain

Using only traveler-supplied clinical requirements, verify transit cooler/gel-pack/security rules, monitoring, freeze protection, hotel storage reliability and access, power-failure backup, and nearby pharmacy or medical fallback. Include related transport, storage, monitoring, and contingency costs in the budget.

## Completion rule

Produce a hard-constraint table. Any unknown or failed critical link means **not ready**. Prominent uncertainty is not a substitute for feasibility.
