# Forge Server Bank

## Overview
The bank addon owns the SQF bridge for player accounts, cash and bank balances,
PIN/session handling, transfers, checkout charging, earnings deposits, and
credit-line repayment.

Account truth lives in the extension hot cache. SQF handles Arma-facing
validation, client messaging, session state, and payment integration with other
server addons.

## Dependencies
- `forge_server_main`
- `forge_server_common`
- `forge_server_extension` at runtime for bank extension calls
- `forge_server_org` at runtime for credit-line repayment
- `forge_client_bank` and `forge_client_notifications` for response RPCs

## Main Components
- `fnc_initBank.sqf` initializes all bank stores and helpers.
- `fnc_initModel.sqf` defines account defaults and migration behavior.
- `fnc_initPayloadBuilder.sqf` builds UI, checkout, and organization payment
  context.
- `fnc_initSessionManager.sqf` manages PIN and authorization session state.
- `fnc_initMessenger.sqf` sends account syncs, alerts, and notifications.
- `fnc_initStore.sqf` wraps hot bank calls and account mutations.

## Supported Operations
- initialize and hydrate player bank state
- deposit, withdraw, transfer, and deposit earnings
- validate PIN-backed sessions
- charge checkout previews and committed purchases
- repay organization credit lines with rollback on failure
- save hot bank state to durable storage

## Runtime Notes
`forge_server_main_fnc_saveHotState` saves bank hot state on disconnect and
mission shutdown. Store checkout and task rewards use this addon for
authoritative player balance changes.
