# Account History

Displays the transaction history for a single account. Opened by tapping an account row in the accounts list.

---

## Fragment — `AccountHistoryFragment`

Receives the selected `MibAccount` via navigation arguments.

---

## Data Loading

On open, the fragment calls the appropriate bank API to fetch the first page of transactions:

| Bank | API |
|---|---|
| MIB | MIB transaction history endpoint (Blowfish-encrypted) |
| BML | BML transaction history endpoint (OAuth Bearer) |
| Fahipay | Fahipay wallet transaction list |

Results are mapped to a common display model and shown in a `RecyclerView`.

---

## Infinite Scroll

The list supports **infinite scroll** (pagination). When the user scrolls near the bottom of the loaded items, the next page is automatically fetched and appended. A loading spinner appears at the bottom while a page is in flight.

Page state (current page, total pages) is tracked in the fragment's `ViewModel`. If the last page has been reached the spinner is hidden and no further requests are made.

---

## Search / Filter

A search bar at the top of the screen filters the loaded transaction list by:
- Description / narrative text
- Amount string

Filtering is performed locally on already-loaded pages — it does not trigger a new API call. Clearing the search bar restores the full list.

---

## Transaction Rows

Each row shows:
- Transaction date and time
- Description / merchant name
- Debit or credit indicator
- Amount (hidden as `••••` when hide-amounts is active)
- Running balance (where available from the bank API)

---

## Image Loading

Some MIB transaction entries include merchant logo URLs. These are loaded asynchronously into the row's image view with a generic fallback icon. Images are cached in memory for the session.

---

## Empty State

If no transactions exist (new account or API returned empty list) an empty-state message is shown.
