NEXT SESSION PROMPT

# Next Session Prompt v2.4

**For**: anomaly-notification-ui | **Created**: 2026-01-30 | **Pairs with**: Transfer Pack v2.3

> Paste the **Session Start Prompt** below as the first message of the next session,
> after uploading the updated PACK docs (MASTER_REFERENCE v1.4, ROADMAP v2.1,
> TRANSFER_PACK v2.3).
>
> **Transfer Pack vs. Next Session Prompt** — the Transfer Pack describes where we left
> off (cost anomaly backend complete). This is the executable kickoff: the message to
> paste, the guardrails, and the one decision to settle before building the UI.

## Pre-Paste Snapshot

Confirm each item before pasting. If any ❌, fix it before starting the session.

| # | Check | Expected state |
|---|-------|----------------|
| 1 | Cost anomaly backend (Phases 1-2) | ✅ COMPLETE — do not re-implement the pipeline |
| 2 | `cost_anomalies` migration | ✅ Applied (`20260130_cost_anomalies.sql`) — do not edit schema |
| 3 | Type-check baseline | 0 errors on `main` after Phase 2 merge |
| 4 | First target this session | `AnomalyBanner.tsx` notification UI (P0, task #1) |
| 5 | Threshold decision (critical vs. warning) | ⏸️ UNRESOLVED — answer at session start |
| 6 | Hard rule | Reuse existing `NotificationProvider`; do not build a second notification system |

If all ✅ (and ⏸️ items are queued as the open question) → proceed.
