# Customer App Flow — Mermaid Diagrams

> Generated from `requirement/flow_customer.md` and cross-checked against the Figma
> handoff package (`requirement/Figma/` — git-ignored).
>
> **Legend (status pulled from a client_app audit, see `phase4-customer-flow.md`):**
> - 🟢 EXISTS — already shipped in client_app
> - 🟡 PARTIAL — close, but a key piece (UX, copy, or sub-state) is missing
> - 🔴 MISSING — no implementation in client_app yet

The flow is split into 6 sub-diagrams so each one stays readable. Screen IDs use
the Figma handoff naming (`S1`, `S6`, `S10`, …); see `Figma/handoff/png/` for the
909×540 renders and `Figma/screens/*.jsx` for the live source.

> **ESP screening removed (2026-05-12):** the S5 ESP multi-select chip
> screen is retired from the spec. Both verified and anonymous branches
> now go from `VerifChoiceSheet` straight to the `usp_seen?` gate. Any
> ESP code still in `client_app` is now tech debt to retire — see
> `TECH_DEBT.md`.
>
> **S5b USP is one-time-only (2026-05-12):** the USP screen now shows at
> most once per user. Gating is driven by a `usp_seen` flag that lives in
> two places:
> - **Local (SharedPreferences):** the runtime gate. Set to `true` when the
>   user dismisses the USP screen for the first time. Survives across
>   sessions on the same device.
> - **DB (`customers.usp_seen` column 🔴):** the cross-device source of truth.
>   Written when the user account is created (post-OTP, after JWT issuance
>   and `users` row insert) if local flag is already true, OR on any
>   subsequent USP dismissal once an account exists. Read on login/relogin
>   and hydrated back into local. "True wins" — if either side says seen,
>   the gate is closed.
>
> Anonymous users with no account only have the local flag; if they later
> upgrade to verified, account creation propagates the local flag to DB.
> Returning verified users on a fresh device will see USP at most once on
> that device (DB hydrate happens on login, after USP gate fires pre-OTP).
> Business has accepted this edge case.
>
> **Anchor mismatch:** flow_customer.md numbers ESP/USP under
> `5.1.2 Verification request (OTP)` for both branches, but Figma puts
> `VerifChoiceSheet` *before* ESP. The mermaid above follows Figma; reconcile in
> phase4 spec.
>
> **Post-OTP account lookup (added 2026-05-11):** the verified path is not
> always "new user". After a successful OTP, the backend looks up the phone
> number; if a row exists, the app overwrites the freshly-typed call_sign with
> the stored one. Then `has_transacted` decides routing:
> - `false` → S6 Paywall (Rp2.000 first-session) — user has an account but
>   never converted.
> - `true` → jump straight into `PickMethod` (the regular chat/voice +
>   duration + payment flow). USPb is already skipped because USPGateA
>   already evaluated pre-OTP on the verified branch.
>
> `has_transacted` is the persistent flag on the users table that flips the
> first-time pricing off forever. Backend phone-lookup behaviour already
> exists (see Phase 1 auto-link via phone); the app-side reconciliation +
> `has_transacted` plumbing is the new work.

  classDef partial fill:#fff4d6,stroke:#c69b3f
  class ChatRedirect,Aktif,Pembayaran,Selesai,AktifEmpty,PembayaranEmpty,SelesaiEmpty partial
```

**Data sources**
- Aktif → existing `GET /api/client/chat/session/active-with-unread` (0 or 1 row)
- Pembayaran → new `GET /api/client/payment-sessions/pending` (filters `status='pending' AND expires_at > NOW()`)
- Selesai → existing `GET /api/client/history`, migrated to cursor pagination (`{ items, next_cursor, has_more }`)

**Badges**
- Bottom-nav `chat` tab → red dot when Pembayaran `total > 0`
- `aktif` sub-tab pill → numeric badge from `unread_count`
- `pembayaran` sub-tab pill → numeric badge from `total`
- `selesai` sub-tab pill → no badge
