Stages 5.1, 5.3, 5.4 of the returning-user flow rework. All three §4
entry paths now require payment BEFORE pairing, matching the updated
mermaid spec.
* Spec (requirement/flow_customer.mermaid.md §4): payment block converges
three call-sites (bestie-yang-udah-kenal-online, bestie-baru,
offline-popup → cari bestie lain). PairRoute dispatches lama → targeted
pair, baru/cari-lain → §3 blast. §3 retains its post-payment-shared
contract.
* Stage 5.1 (client_app): PaymentDraft carries targetedMitraId +
topicSensitivity. bestie_history_list seeds the draft + pushes
/payment/entry (was legacy /payment). searching_screen branches on
draft.targetedMitraId for blast-vs-targeted dispatch.
payment_entry uses resetExceptTarget(); bestie_choice_sheet + home
_onCurhatBestieBaruPressed call explicit reset() before push so
the keepAlive draft can't leak stale targeting into a blast.
* Stage 5.3 (client_app): new BestieOfflineVariant.prePayReturning.
Bestie-history-list _BestieRow splits tappable from dim so offline
rows render dimmed but route taps into the popup. CTA "cari bestie
lain" resets the draft + pushes /payment/entry.
* Stage 5.4 (client_app): deleted legacy /payment route,
payment_screen.dart, payment_notifier.dart(+.g.dart). router cleaned.
* Tests (requirement/phase4-customer-flow.md + client_app/.maestro/):
six Maestro flows TS-01..TS-06 covering every §4 branching point,
all passing end-to-end. Shared onboarding prelude under
.maestro/subflows/. New helper scripts: accept_latest_pending,
force_mitra_offline, force_other_mitra_online,
reset_all_mitras_online, mitra_accept_latest_internal. New backend
_test endpoints to match. /reset-phone now cascade-deletes
customer_transactions (FK was blocking). /force-pairing-timeout
branches targeted (RETURNING_CHAT_TIMEOUT via
expireTargetedPairingRequest, now exported) vs blast (PAIRING_FAILED).
seed_history_session also outputs MITRA_NAME_RE (regex-escaped) for
reliable selectors against display names containing regex specials.
* mitra_app: dispose-during-deactivate guardrail for back-press on the
mitra chat screen after the customer's goodbye message. Pending real
emulator repro verification (carried over from 2026-05-15).
