+# 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.
