The /web/ prefix predated the /api/ split; today it just clutters every URL
without disambiguating anything. All 16 browser routes move to the apex
(/cases, /login, /magic, /events, /audio/...). The 6 /api/* routes are
unchanged. A new /->>/cases redirect closes the apex 404.
The open-redirect guard in magic.rs and case_actions.rs flips from a
positive whitelist (starts_with("/web/")) to a deny-list: same-origin path,
not protocol-relative, not under /api/, no \. The /api/ exclusion is now
load-bearing and covered by tests.
Pre-production: no transition redirects.
Introduces a system for broadcasting real-time events to the web UI.
This enables features like automatic page reloads when case data changes
in the background, improving the user experience by keeping the UI
synchronized with the backend.
Key components:
- `events` module: Contains the `CaseEventKind` enum, `CaseEvent`
struct, and `EventSender` type for managing the broadcast channel.
- SSE endpoint (`/web/events`): Streams events to connected browsers.
- Client-side JavaScript: Listens for events and triggers debounced page
reloads.
- Integration points: Workers and route handlers now emit events when
relevant state changes occur.
