[Bug]: payment request lists diverge after cross-device pay

[piotr-iohk]

What happened?

Two live wallets (iOS sim ios ↔ Android emu andi) each created 2 private payment requests (1k Lightning + 25k on-chain) and paid the other side’s requests. All 4 payments settled. Each Payment Requests list then showed 3 rows, and they did not match:

• iOS: 2× 25 000 + 1× 1 000 (missing one 1k)
• Android: 1× 25 000 + 2× 1 000 (missing one 25k)

The missing 1k did pay (iOS → Android LN, proof queued). The missing 25k did pay (Android → iOS on-chain e418fd9b…, iOS activity +25 000, proof queued). So this is a history-row drop, not a failed payment.

Not same-amount overwrite in the app list: IDs are paymentRequestId + counterparty + receiverPath. Hypothesis: after fulfill, one side drops the row when localRole is missing/unknown (history mapping skips those).

Seen twice (2026-09-01 and 2026-09-02) on #683 / #1178 builds.

Expected behavior

After 4 created + 4 paid requests between the same pair, both devices show the same 4 rows (2× 1k + 2× 25k).

Steps to Reproduce

1. Two wallets, private Paykit + contact payments enabled, same contact pair.
2. iOS creates 1k Lightning request; Android pays it.
3. Android creates 1k Lightning request; iOS pays it.
4. iOS creates 25k on-chain request; Android pays it (or the reverse order used in the recording).
5. Android creates 25k on-chain request; iOS pays it.
6. Open Payment Requests on both devices.

Bitkit Version

iOS #683 (489b1e6 / fix: lock incoming request amounts + later). Cross-tested vs Android #1178 (10ff0df).

Device / OS

iPhone 17 simulator, iOS 26.0 (paired with Pixel emulator)

Reproducibility

Always (2/2 sessions)

Additional context

• New wallets, regtest
• Lightning + on-chain
• Amount pad on incoming pay is fixed on this iOS build (Confirm, amount locked). Do not mix that into this bug.
• Proofs queued on all 4 pays (Queued a Paykit payment proof for private delivery). This bug is list/history only.
