# Dashboard Behaviors

## Overview

The Dashboard is an admin-only, SSR-based overview page that displays financial summary cards across selected clients. It provides at-a-glance visibility into bank account balances, outstanding tasks, recent sales trends, expense breakdowns, and profit/loss summaries. Cards are loaded lazily via HTMX for progressive rendering.

## Routes

| Route | Handler | Purpose |
|-------|---------|---------|
| `GET /` | `::page` | Main dashboard page with stub cards |
| `GET /expense-card` | `::expense-card` | Expense pie chart (top 5 accounts, last month) |
| `GET /pnl-card` | `::pnl-card` | Profit & Loss bar chart (last month) |
| `GET /sales-card` | `::sales-card` | Gross sales bar chart (last 14 days) |
| `GET /bank-accounts-card` | `::bank-accounts-card` | Bank account balances and sync status |
| `GET /tasks-card` | `::tasks-card` | Unpaid invoices and uncategorized transactions |

## Behaviors

### Unit Test Behaviors

- `extract-client-ids` returns intersection of user's allowed clients and requested clients
- `is-admin?` returns true only when `user/role` equals `"admin"`
- Client trimming takes only first 20 clients from the valid set
- `clients-trimmed?` is true when the count of trimmed clients differs from valid clients
- Bank account card excludes accounts with `bank-account-type/cash`
- Bank account card displays ledger balance formatted as `$X,XXX.XX`
- Bank account card shows sync timestamp in `standard-time` format when present
- Sales chart queries use ISO date range from 14 days ago to tomorrow
- Expense pie chart queries use date range from 1 month ago to tomorrow
- P&L card aggregates accounts into `:sales` and `:cogs :payroll :controllable :fixed-overhead :ownership-controllable` categories
- Tasks card queries invoices with `invoice-status/unpaid` and transactions with `transaction-approval-status/requires-feedback`
- Tasks card only renders task sections when counts are non-zero

### Integration Test Behaviors

- Main page `GET /` returns 200 with base layout and 6 stub cards for admin users
- Each card endpoint returns 200 with HTML response containing chart canvas or data
- Bank accounts card performs Datomic pull for each client's bank accounts with nested Intuit/Yodlee/Plaid data
- Sales card executes Datomic query summing `sales-order/total` by ISO date
- Expense card executes Datomic query summing `invoice-expense-account/amount` by account name
- P&L card calls GraphQL `get-profit-and-loss-raw` with trimmed client IDs and last-month date range
- Tasks card executes two separate Datomic queries for unpaid invoices and uncategorized transactions
- Expense breakdown card (from `company/reports/expense`) executes query with optional vendor and account filters
- All card endpoints apply `wrap-trim-clients` and `wrap-admin` middleware
- Non-admin requests to any dashboard route receive 302 redirect to `/login`
- Unauthenticated requests receive 302 redirect to `/login` with `redirect-to` parameter

### UI Test Behaviors (SSR)

#### Happy Path: Dashboard Loads Successfully
1. Admin user navigates to `/`
2. Page renders with main navigation, client selector, and breadcrumb "Dashboard"
3. Six stub cards appear with loading spinners:
   - Expenses (pie chart)
   - Tasks
   - Bank Accounts (tall card, row-span-2)
   - Gross Sales, last 14 days (bar chart)
   - Profit and Loss, last month (horizontal bar chart)
   - Expense breakdown (bar chart, wide card)
4. Each stub card triggers `hx-get` on load to fetch its content
5. Cards progressively render with actual data
6. User sees bank account balances, task counts, sales chart, expense charts, and P&L summary

#### Card Interactions
- Bank Accounts card displays each client's name, account name, ledger balance, and last sync time
- When a bank account has Intuit/Yodlee/Plaid sync, the external balance and sync time display alongside the ledger balance
- Yodlee accounts additionally show "Pending Txs" with pending balance
- Tasks card shows "Pay now" link for unpaid invoices (links to unpaid invoices page with `date-range=year`)
- Tasks card shows "Review now" link for uncategorized transactions (links to requires-feedback transactions page)
- Expense breakdown card has Vendor and Account typeahead filters
- Changing Vendor or Account filter triggers HTMX request to reload the breakdown chart with filtered data
- Expense breakdown chart updates URL via `hx-push-url` with query params

#### Client Selection Effects
- User selects different clients from the client dropdown
- Page triggers `clientSelected` event on body
- HTMX swaps `#app-contents` with fresh dashboard content for newly selected clients
- All cards re-fetch with new client context
- If more than 20 clients selected, a yellow warning banner appears: "Warning: These reports are only for twenty of the selected customers. Please select a specific customer to see more detail."

## Edge Cases

### No Clients Selected
- Dashboard page renders but all cards show empty state
- Bank Accounts card renders empty list
- Sales chart shows empty bar chart with no data points
- Expense pie chart shows empty pie chart
- P&L card shows zero income and expenses
- Tasks card shows no task notifications (sections hidden when count is zero)

### Many Clients (Trimming Warning)
- When user has access to more than 20 clients and selects all, only first 20 are used
- Yellow warning banner displays below breadcrumb
- All card queries execute against trimmed client set only
- Warning persists across client selection changes until fewer than 21 clients selected

### No Data for Date Ranges
- Sales chart (14-day window): Empty chart renders with no bars when no sales orders exist
- Expense pie chart (last month): Empty pie chart renders when no invoices with expense accounts exist
- P&L card: Shows `$0.00` for both income and expenses
- Tasks card: No task sections render (conditional on non-zero counts)
- Bank Accounts: Accounts still display with zero/null balances if they exist but have no transactions

### Error Loading Individual Cards
- Each card loads independently via separate HTMX request
- Failure in one card endpoint does not prevent other cards from loading
- Stub card shows spinner until successful response or timeout
- Server errors in card endpoints return appropriate HTTP status without breaking page layout

### Permissions (Admin vs User)
- Only users with `user/role = "admin"` can access dashboard routes
- Non-admin authenticated users receive 302 redirect to `/login`
- Unauthenticated users receive 302 redirect to `/login` with `redirect-to` parameter
- Admin role is verified by `wrap-admin` middleware before any data queries execute

### Bank Account Sync States
- Account with no external sync (Intuit/Yodlee/Plaid): Shows only ledger balance and sync time
- Account with Intuit sync: Shows Intuit balance and last synced timestamp
- Account with Yodlee sync: Shows available balance, last synced timestamp, and pending balance
- Account with Plaid sync: Shows Plaid balance and last synced timestamp
- Missing/null balances display as `$0.00`

## Test Data Requirements

### Users
- Admin user (`:user/role "admin"`) with access to multiple clients
- Non-admin user (`:user/role "user"`) to test permission denial

### Clients (minimum 2, ideally 25+)
- Client with `client/name` and at least one bank account
- Mix of clients with Intuit, Yodlee, and Plaid synced accounts
- Client with `:bank-account-type/cash` account (should be excluded from display)

### Bank Accounts
- Bank account with `:bank-account/current-balance` and `:bank-account/current-balance-synced`
- Bank account linked to Intuit (`:bank-account/intuit-bank-account`)
- Bank account linked to Yodlee (`:bank-account/yodlee-account` with available + pending balance)
- Bank account linked to Plaid (`:bank-account/plaid-account`)

### Sales Orders
- Sales orders dated within last 14 days with `:sales-order/total`
- Sales orders dated outside 14-day window (should not appear)

### Invoices
- Invoices with `:invoice/expense-accounts` (with `:invoice-expense-account/amount` and `:account/name`) within last month
- Invoices with `:invoice/status :invoice-status/unpaid` within last year
- Invoices with `:invoice/outstanding-balance`
- Voided invoices (should be excluded from expense breakdown)

### Transactions
- Transactions with `:transaction/approval-status :transaction-approval-status/requires-feedback` within last year
- Transactions with `:transaction/amount`

### P&L Data
- Chart of accounts with categories `:sales`, `:cogs`, `:payroll`, `:controllable`, `:fixed-overhead`, `:ownership-controllable`
- Account balances within last month for selected clients

## Dependencies

### External Services
- **Datomic**: All card data queried from Datomic database
- **GraphQL endpoint**: P&L card calls `get-profit-and-loss-raw` (Lacinia GraphQL)
- **Intuit/Yodlee/Plaid**: Bank account sync data for external balances (data stored in Datomic)

### Frontend Libraries
- **HTMX**: Progressive card loading via `hx-get`/`hx-trigger`/`hx-swap`
- **Chart.js**: Canvas-based chart rendering (bar, pie, horizontal bar charts)
- **Alpine.js**: Chart data binding via `x-data`/`x-init` attributes

### Middleware Stack
- `wrap-admin`: Enforces admin-only access
- `wrap-client-redirect-unauthenticated`: Handles auth redirects
- `wrap-trim-clients`: Limits client scope to 20
- `wrap-hydrate-clients`: Populates client data in request
