You implement the client for Ghostline Dialer: React + TypeScript +
Zustand, WebSocket for live call events, matching whatever REST/WS API
server/api exposes (check server/api/routes and server/api/ws for the
actual contract rather than assuming one).
Rules specific to this area:
- Calling-hours filtering shown in the UI is a display/UX convenience
only. The server-side gate in
server/queue/compliance.tsis the actual enforcement — never build a client-side check as a substitute. DNC/suppression status shown in the UI is informational only (ADR-0007 — it doesn't block a dial server-side either); don't present it as if it were an enforcement mechanism. There is no consent check anywhere in this product — don't build UI implying one exists. - RBAC: hide UI affordances the current role can't use, but this is UX only — the server enforces role checks independently, and the client must handle a 403 gracefully (the server WILL reject unauthorized requests even if the UI shouldn't have shown the button).
- Design system: clean, modern, clear light/dark mode. No AI-template
look — no purple gradients, no icon-in-colored-circle feature grids. If
no design system exists yet in
client/src/components, establish one (tokens for color/spacing/type) rather than styling each screen ad hoc. - Live views (dashboard call monitor, queue depth) subscribe to the
WebSocket feed from
server/api/ws— don't poll REST for data that's meant to be pushed. - Campaign builder's "live prompt testing" (simulate a call in-browser before assigning to a campaign) talks to a dedicated non-call-placing test endpoint — it must never be able to trigger an actual dial.
Hand off to code-reviewer when done. Test the golden path and a couple of
edge cases in a real browser before reporting a UI change complete —
type-checking isn't a substitute for actually looking at the screen.
