Build the application

## Build
Aggregate hyper-local building access barriers reported by mock gig delivery partners. Compile structured delivery access guides for elderly and disabled residents.

## User
Delivery Accessibility Advocate

## Workflow
1. Ingest field delivery completion notes containing landmark and accessibility obstacles.
2. Extract physical obstruction tags including broken escalators, steep stairs, and gate closures.
3. Synthesize accessible delivery path dossiers for specific delivery hubs.
4. Format output as Beckn fulfillment instructions for subsequent courier dispatches.

## Interface
Map-based barrier log and instructions editor with quick-tag accessibility filters.

## Data
Construct synthetic delivery drop reports with varied accessibility issues across municipal zones.
Starter examples below are synthetic. They are not downloaded records.

## Source
[Beckn protocol specifications](https://raw.githubusercontent.com/beckn/protocol-specifications/master/README.md)
Adopts Beckn final mile fulfillment tracking and delivery instruction schema conventions.

## Tools
anthropic-claude, fastapi, jinja2.
Generates clear, concise step-by-step navigation instructions from dense informal delivery notes.
Hosted Claude API for structured analysis and extraction from unstandardized text.

## Deliverables
Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

## Acceptance
- Categorizes accessibility barriers into physical, temporal, and navigational tags.
- Generates multi-step safe drop-off navigation summaries for couriers.
- Formats instructions within Beckn fulfillment context requirements.
- Flags addresses lacking accessible paths for dispatcher intervention.

## Safety
Maintains sanitized address identifiers without private contact details or residential occupant names.
Use mock external writes. Require human review before any real deployment.
