## Known Gaps in Existing System (Pre-Work)

These are not new features — they are fixable holes in what's already built.
They must be resolved before new feature steps begin because later steps depend on correct foundations.

| Gap | Impact |
|---|---|
| Route DTOs missing RegionId | Can't link routes to regions via API |
| Store DTOs missing RouteId | Can't link stores to routes via API |
| Role endpoints have no [Authorize] | Anyone can read roles without authentication |
| JWT key & DB credentials in appsettings.json | Security risk in any shared/production environment |
| No input validation on any DTO | Bad data can enter the system silently |
| Item model is empty (no properties) | OrderItems reference items that have no data |

## Function Reference by Feature

Reference only, not a build plan — background material to consult while planning/implementing the
steps above and below. Service-layer function names and what each should do when implemented.
Names are illustrative (camelCase) — adapt to your language/framework conventions. None of the
functions below are implemented yet unless noted. User Management/RBAC functions aren't repeated
here — see `SRS_User_Management_Module.pdf`.

### 1. Order Management

| Function | What it does | Status |
|---|---|---|
| `createOrder(storeId, items[], salesRepId)` | Validates stock/credit, creates a new order in `pending` state. | Partially implemented - `OrderService.CreateAsync` exists, enforces store scope, blocks inactive stores, and applies the unverified-KYC order threshold from config. It still has no stock validation, credit-limit validation, approval flow, or order state machine. |
| `validateCreditLimit(storeId, orderAmount)` | Checks store's outstanding balance + new order value against its credit limit. | Not implemented - `Store` now has `CreditLimit` and `OutstandingBalance`, but there is no dedicated validator or order-time credit-limit enforcement yet. |
| `checkStockAvailability(items[])` | Confirms requested SKUs/quantities are available at the fulfilling warehouse. | Not implemented — depends on [02_stock_ledger.md](./02_stock_ledger.md). |
| `applyPricingAndDiscounts(orderId)` | Runs the active price list and eligible scheme rules against order lines. | Partially implemented — `OrderService.CreateAsync` resolves the price-list half via `PriceListService.ResolveUnitPriceAsync` (region-scoped → global → `Item.SalePrice`, or a caller-supplied `UnitPrice`); the scheme-discount half still depends on §11 Promotions below. |
| `submitOrderForApproval(orderId)` | Routes the order to the correct approver based on its value/discount threshold. | Not implemented — depends on [08_sales_agent_controls.md](./08_sales_agent_controls.md). |
| `approveOrder(orderId, approverId)` / `rejectOrder(orderId, reason)` | Moves order to `approved` or `rejected`, logging the actor. | Not implemented. |
| `updateOrderStatus(orderId, status)` | Transitions order through `pending → approved → picked → dispatched → delivered → invoiced`. | Not implemented — `Order` has no status field or state machine today. |
| `convertOrderToInvoice(orderId)` | Generates the invoice once the order is dispatched/delivered. | Not implemented — depends on §13 Finance & Accounting. |
| `createBackorder(orderId, unfulfilledItems[])` | Splits unfulfillable quantity into a linked backorder. | Not implemented. |
| `cancelOrder(orderId, reason)` | Cancels an order pre-dispatch and releases any reserved stock. | Not implemented — `OrderController` supports soft delete only, no reason code or stock release. |
| `getOrdersByStore(storeId)` / `getOrdersBySalesRep(salesRepId)` | Scoped order listings. | `getOrdersByStore` implemented (`GET /api/orders/store/{storeId}`). `getOrdersBySalesRep` not implemented. |
| `getOrderAnalytics(filters)` | Returns fill rate, average order value, rejection rate over a period. | Not implemented. |

### 2. Region Management

| Function | What it does | Status |
|---|---|---|
| `createRegion(name, boundaries)` | Creates a new region record. | Partially implemented — `RegionController` supports create with `Name` only, no `boundaries` field. |
| `assignAreaToRegion(areaId, regionId)` | Links an existing area under a region. | Not implemented — no `Area` entity exists in the schema. |
| `setRegionalTarget(regionId, period, targetValue)` | Sets the sales target for a region for a given period. | Not implemented. |
| `setRegionalBudget(regionId, period, budgetAmount)` | Allocates budget at the regional level. | Not implemented. |
| `mapAgencyToRegion(agencyId, regionId)` | Assigns a Regional Agency's contract scope to a region. | Not implemented — `RegionalAgency` is currently a `Role`, not a distinct agency entity; scope is via `UserRegionScope`. |
| `setRegionalTaxRule(regionId, ruleConfig)` | Overrides tax/pricing rules for a specific region. | Not implemented. |
| `getRegionHierarchy(regionId)` | Returns all areas/territories nested under a region. | Not implemented — see [user_management_PLAN.md](../user_management_PLAN.md) territory hierarchy prerequisite. |
| `getRegionDashboard(regionId, period)` | Aggregated KPIs: sales, fill rate, agency performance for the region. | Not implemented. |

### 3. Route Management

| Function | What it does | Status |
|---|---|---|
| `createRoute(name, areaId)` | Creates a new sales visit route within an area. | Partially implemented — `RouteController` supports create, but by `RegionId` not `areaId` (no `Area` entity exists). |
| `assignOutletsToRoute(routeId, outletIds[])` | Maps a set of stores to a route. | Partially implemented — a `Store` has a single `FK_RouteId`, set via `StoreController` create/update; no bulk-assign endpoint. |
| `assignRouteToSalesRep(routeId, salesRepId)` | Assigns ownership of a route to an SR. | Not implemented — only `UserRouteScope` exists (scope grant), not a single-owner assignment. |
| `optimizeRouteSequence(routeId)` | Reorders the visit sequence for efficiency (distance/priority-based). | Not implemented. |
| `recordRouteCheckIn(routeId, outletId, gpsCoords, timestamp)` | Logs an SR's arrival at an outlet. | Not implemented. |
| `recordRouteCheckOut(routeId, outletId, timestamp)` | Logs departure and closes out the visit. | Not implemented. |

### 4. Store (Outlet) Management

| Function | What it does | Status |
|---|---|---|
| `createStore(storeData, kycDocs)` | Onboards a new outlet with required KYC. | Partially implemented - store create exists, and KYC documents can now be uploaded/listed via separate `/api/stores/{id}/kyc-documents` endpoints rather than inline on create. |

| `updateStoreCreditLimit(storeId, newLimit, approverId)` | Changes a store's credit limit, subject to approval authority. | Implemented - `PUT /api/stores/{id}/credit-limit` updates `Store.CreditLimit` and requires the `stores.credit.update` permission plus role level >= 20. |
| `getStoreOutstandingBalance(storeId)` | Returns current receivables against the store. | Partially implemented - `GET /api/stores/{id}/outstanding-balance` returns the cached `OutstandingBalance`, `CreditLimit`, and available credit. It is not yet driven by Finance events or invoice/payment records. |
| `classifyStore(storeId, segment)` | Sets/updates the store's segment (key account, general trade, etc.). | Implemented - `PUT /api/stores/{id}/segment` updates the free-text `Store.Segment` field. |
| `deactivateStore(storeId, reason)` | Soft-deletes a store, blocking new orders against it. | Partially implemented — `DELETE /api/stores/{id}` soft-deletes via `IsActive`, no reason code captured. |
| `getStoreVisitHistory(storeId)` | Returns visit compliance history from Route Management. | Placeholder only - endpoint exists (`GET /api/stores/{id}/visit-history`) but currently returns an empty list until Route/Sales Visit Management lands. |
| `checkStoreSchemeEligibility(storeId, schemeId)` | Evaluates whether a store qualifies for a given promotion. | Placeholder only - endpoint exists (`GET /api/stores/{id}/schemes/{schemeId}/eligibility`) but currently returns a default eligible response until Promotions is implemented. |
| `getStoreSalesDashboard(storeId, period)` | Store-level sales and outstanding summary. | Partially implemented - `GET /api/stores/{id}/dashboard` aggregates order count, total order value, and last order date for the selected month. It does not yet include full sales/outstanding analytics from Finance. |

## Feature Summaries

### 00 — Existing Gap Fixes
Fix all known holes in the current codebase before new features are layered on top.
Includes DTO field gaps, missing authorization on role endpoints, secrets management,
and adding input validation across all existing endpoints.
**Gate**: All existing API endpoints behave correctly and securely before step 01 begins.

### 01 — Item Catalog
Define the Item entity with real properties (name, SKU, unit of measure, category, price tiers).
Items are the unit of stock — nothing in the stock ledger makes sense without them.
This step also covers the Item CRUD API and how items relate to orders.
**Gate**: An item can be created, updated, and referenced in an order with quantity and price.

### 02 — Stock Ledger
Introduce the concept of stock per location. Every warehouse (fixed or vehicle) holds a quantity
of each item. Stock is never edited directly — all changes happen through movement transactions
(load, sale, return, damage, adjustment). The current balance is always the running sum.
This is the single most important architectural decision for the whole system.
**Gate**: Stock balance for any item at any location can be queried. Every change is a traceable transaction.

### 03 — Ride Lifecycle
A ride is a session that turns a vehicle into a temporary warehouse. It has a state machine:
Draft → Open → Active → Closed. A vehicle can only be on one active ride at a time.
Two ride types exist: Delivery (pre-orders) and Sale (van sales). The ride tracks who is driving,
which route, which vehicle, and when it started and ended.
**Gate**: A ride can be created, opened, and closed. A vehicle's stock ledger is created when a ride opens.

### 04 — Loading Event
When a ride opens, stock must be physically loaded from a source warehouse onto the vehicle.
This is a two-party event: warehouse manager confirms what was dispatched, driver confirms what was received.
Discrepancies between the two are flagged immediately and require resolution before the ride goes active.
The loading event creates stock movement transactions that debit the warehouse and credit the vehicle.
**Gate**: Stock moves from warehouse to vehicle via a confirmed loading event. Any discrepancy is logged.

### 05 — Delivery Ride Execution
On a delivery ride, the driver fulfills pre-confirmed orders. Each order becomes a delivery task.
The driver marks each as delivered, partially delivered, or failed. Partially delivered orders
generate a credit note for the undelivered quantity. Customer confirmation (signature or OTP)
is required to mark a delivery complete. Stock movements are created per delivery event.
**Gate**: A delivery ride can execute all orders on its route and produce a delivery report.

### 06 — Sale Ride Execution
On a sale ride, the driver visits customers and creates invoices on the spot. No pre-orders exist.
The driver selects items, quantities, and prices (within approved discount limits), and the invoice
is generated immediately. Payment is collected (cash or credit) at the point of sale.
The vehicle's stock ledger decreases with each sale. The driver cannot sell more than what is loaded.
**Gate**: A sale ride can generate invoices in the field. Stock on vehicle decreases with each sale.

### 07 — Ride Close & Reconciliation
When a ride ends, the system performs a full reconciliation. The equation must balance:
  Opening Stock − Sales − Damages + Returns = Closing Stock (physical count)
  Cash Collected + Credit Extended = Total Sales − Returns
Any variance must be approved by a supervisor with a reason code before the ride can close.
Unresolved variances are logged as discrepancies against the agent's record.
**Gate**: A ride cannot close with an unexplained variance. All discrepancies are permanently recorded.

### 08 — Sales Agent Controls
Agents operate within boundaries set by their role level. This step wires role levels to business rules:
discount limits per agent level, credit limits per customer, maximum single-transaction value,
and approval chains for exceptions. Supervisors can grant one-time overrides logged against their account.
**Gate**: An agent cannot exceed their limits without a logged, authorized override.

### 09 — Fraud Controls & Audit Trail
A dedicated audit log records every sensitive event (who, what, when, from where).
Automated checks flag: returns without a matching prior sale, sales outside the geofenced route,
agents with consistently high variance rates, and cash collected below invoiced amounts.
Return approval requires supervisor sign-off before stock is credited. Anomaly reports are
surfaced to area managers on a scheduled basis.
**Gate**: Every sensitive event is logged immutably. Automated flags surface to the right level of management.

## Rules

1. A feature file must be filled in and reviewed before implementation begins on that step.
2. Status must be updated in this file whenever a step transitions.
3. If implementation reveals a design change, the feature file is updated and this plan is revised.
4. Steps must be done in dependency order — no skipping.
