Lite mode: local-only dispatch workflow with browser storage, CSV export, and manual wipe

[evanqua]

Summary

Add a Lite mode that runs entirely in-browser with no backend persistence. In Lite mode, users create an event from scratch, run dispatch locally, export CSV, and optionally wipe all local data.

Motivation

Some teams need a privacy-first workflow where no user-entered operational or patient data is sent to cloud services. Lite mode also reduces setup friction and supports low/no-connectivity operations.

Proposed solution

• Add dedicated Lite routes under /lite in the same Next.js app.
• Build a separate Lite event creation page (do not reuse cloud create flow with mode toggles).
• Lite create page should include essential setup only:
  • Event name/date
  • Teams
  • Supervisors
  • Posts (text locations; no map UI)
  • Posting schedule
  • Equipment
• Do not support venue presets in Lite; users create event setup each session/event.
• Generate a local event ID in-browser and persist data locally (IndexedDB recommended).
• Route from Lite create to Lite dispatch using local ID (/lite/events/[localEventId]/dispatch).
• Add CSV export directly from Lite dispatch/end-event flow.
• Add “Wipe local data” action to clear all Lite records.
• Ensure Lite mode has no Firebase/Auth/Firestore/DataConnect writes or reads for event data.

Alternatives considered

• Reusing existing cloud event create/dispatch pages with conditional branches. Rejected due to heavy Firebase coupling and higher risk of accidental backend writes.
• Storing “non-HIPAA” setup data in backend while keeping patient data local.
  Rejected for Lite v1 to keep guarantees simple: no user-entered Lite data on backend.

Mockups / Examples

• User opens /lite
• User clicks Start Lite Mode
• User completes Lite event creation (no map/presets)
• User is taken to Lite dispatch
• User exports CSV
• User optionally wipes local data

Acceptance criteria

• Lite routes are accessible without cloud authentication.
• Lite mode stores event/dispatch data locally in-browser only.
• Lite mode performs zero Firebase/Auth/Firestore/DataConnect requests for Lite event data.
• Lite create supports teams, supervisors, posts, schedule, and equipment without maps/presets.
• Lite dispatch works from locally created event data and persists across page refresh.
• CSV export includes dispatch logs needed for post-event reporting.
• “Wipe local data” fully clears Lite records and returns user to Lite start page.
• Existing cloud routes and behavior remain unchanged.

Priority

High

Additional context

This issue is an umbrella for Lite v1. Child issues should be created for:

1. Lite routing/shell isolation
2. Lite create page
3. Lite local dispatch persistence
4. CSV export + wipe flow
