Error Toast and Location Validation

Migrated from: obs_vault

Parent: ../modules/UI Components.md

This note covers the user-facing toast system and the location checker used for map-data sanity checks.

Main Source Files

• src/ui/ErrorToast.js
• check-locations.js

What It Does

• ErrorToast renders transient warnings and errors and keeps the latest few visible.
• check-locations.js scans a packaged map for named locations and named geometry so search suggestions have something to work with.

Why It Matters

• This is the support surface for visible failures and for validating that search has meaningful input data.

Risks

• check-locations.js proves names exist, but not that search can actually resolve geometryId and floorId the way the UI needs.
• Toasts need to stay small and disposable or they can hide the map instead of explaining it.
