Fix invoice ProjectName not pre-filling on edit; add to Details view

Edit GET now falls back to job.ProjectName for invoices created before the
column was added. Details view shows Project Name alongside Customer PO.

+## Project Overview
+
+A production-ready ASP.NET Core 8.0 MVC application for managing powder coating business operations. The application implements Clean Architecture with six projects across three layers (Domain, Application, Infrastructure) plus two presentation layers (Web MVC, RESTful API).
+
+## Essential Commands
+
+### Building and Running
+
+```bash
+# Build entire solution
+dotnet build
+
+# Run web application (MVC)
+cd src/PowderCoating.Web
+dotnet run
+# Access at: https://localhost:58461
+
+# Run web with auto-reload
+dotnet watch run
+
+# Run API
+cd src/PowderCoating.Api
+dotnet run
+# Swagger UI at root URL
+
+# Run tests
+dotnet test                                    # All tests
+dotnet test tests/PowderCoating.UnitTests      # Unit tests only
+dotnet test tests/PowderCoating.IntegrationTests  # Integration tests only
+```
+
+### Database Operations
+
+```bash
+# All EF commands run from Web project directory
+cd src/PowderCoating.Web
+
+# Create migration (must specify Infrastructure project)
+dotnet ef migrations add MigrationName --project ../PowderCoating.Infrastructure
+
+# Apply migrations
+dotnet ef database update --project ../PowderCoating.Infrastructure
+
+# Reset database (WARNING: deletes all data)
+dotnet ef database drop --project ../PowderCoating.Infrastructure
+dotnet ef database update --project ../PowderCoating.Infrastructure
+
+# List migrations
+dotnet ef migrations list --project ../PowderCoating.Infrastructure
+
+# Remove last migration (if not applied)
+dotnet ef migrations remove --project ../PowderCoating.Infrastructure
+```

+```
+
+## Architecture Overview
+
+### Clean Architecture Layers
+
+**Domain Layer (PowderCoating.Core)**
+- Contains business entities, enums, and repository interfaces
+- `BaseEntity` provides common properties for all entities (Id, CompanyId, CreatedAt, UpdatedAt, IsDeleted, audit fields)
+- All entities inherit from BaseEntity and support soft delete
+- No dependencies on other projects
+
+**Application Layer (PowderCoating.Application)**
+- DTOs organized by domain (Customer, Job, Equipment, Inventory, Maintenance)
+- AutoMapper profiles with reverse mappings
+- Service interfaces (IFileService, etc.)
+- No UI or infrastructure dependencies
+
+**Infrastructure Layer (PowderCoating.Infrastructure)**
+- `ApplicationDbContext` with global query filters for soft deletes and multi-tenancy
+- Generic `Repository<T>` implementing `IRepository<T>`
+- `UnitOfWork` implementing `IUnitOfWork` with lazy-loaded repositories
+- Seed data is triggered **manually** via Platform Management → Seed Data (not automatic on startup)
+
+**Presentation Layers**
+- `PowderCoating.Web`: MVC application with Razor views, Bootstrap 5 UI
+- `PowderCoating.Api`: RESTful API with JWT authentication, Swagger documentation
+
+### Key Design Patterns
+
+**Repository Pattern**
+- Generic `Repository<T>` in Infrastructure
+- All CRUD operations, search, pagination, eager loading support
+- Soft delete with `SoftDeleteAsync()` method
+
+**Unit of Work Pattern**
+- Coordinates multiple repositories
+- Transaction support: `BeginTransactionAsync()`, `CommitTransactionAsync()`, `RollbackTransactionAsync()`
+- Lazy instantiation of repositories
+- `SaveChangesAsync()` or `CompleteAsync()` to persist changes
+
+**Dependency Injection**
+- All dependencies registered in `Program.cs`
+- Controllers inject `IUnitOfWork` and `IMapper`
+- Services are scoped to request lifetime
+
+**Global Query Filters**
+- Soft deletes: All queries automatically filter `IsDeleted == false`
+- Multi-tenancy: Non-SuperAdmin users see only their company data
+- Bypass with `ignoreQueryFilters: true` parameter in repository methods
+
+### Multi-Tenancy Implementation
+
+- `CompanyId` foreign key on all business entities
+- `ITenantContext` injected into DbContext resolves current company
+- SuperAdmin role can view all companies
+- Global query filters enforce company isolation at database level
+- Users have both system role (SuperAdmin) and company role (CompanyAdmin, Manager, Worker, Viewer)
+
+## Data Access Rules (ENFORCE THESE)
+
+> **`ApplicationDbContext` is NEVER injected into a controller.**
+> All data access in controllers goes through `IUnitOfWork`. No exceptions outside the list below.
+> **This rule is enforced at startup:** `EnforceDataAccessArchitecture()` in `Program.cs` scans all
+> controllers at boot and throws if any non-exempt controller injects `ApplicationDbContext`.
+> Full rationale and permanent exceptions list: `docs/DATA_ACCESS_ARCHITECTURE.md`
+
+### Three tiers — use the right one:
+
+**Tier 1 — Simple CRUD** → `IUnitOfWork.EntityName` (generic `IRepository<T>`)
+```csharp
+var items = await _unitOfWork.CatalogItems.GetAllAsync();
+await _unitOfWork.Announcements.AddAsync(entity);
+await _unitOfWork.CompleteAsync();
+```
+
+**Tier 2 — Complex domain queries** → typed repositories on `IUnitOfWork`
+```csharp
+// Include chains and domain-specific queries belong in the repository, not the controller
+var job     = await _unitOfWork.Jobs.LoadForDetailsAsync(id);
+var invoice = await _unitOfWork.Invoices.LoadForViewAsync(id);
+var quote   = await _unitOfWork.Quotes.GetByApprovalTokenAsync(token);
+```
+Typed repositories: `IJobRepository`, `IInvoiceRepository`, `IQuoteRepository`,
+`ICustomerRepository`, `IBillRepository`, `IPurchaseOrderRepository`
+— defined in `Core/Interfaces/Repositories/`, implemented in `Infrastructure/Repositories/`
+
+**Tier 3 — Aggregate/reporting queries** → injected read services
+```csharp
+// P&L, AR aging, cycle time, powder usage — shaped DTOs, never tracked entities
+var aging = await _financialReports.GetArAgingAsync(companyId);
+```
+Services: `IFinancialReportService`, `IOperationalReportService`
+— defined in `Core/Interfaces/Services/`, implemented in `Infrastructure/Services/`
+
+### Permanent exceptions (ApplicationDbContext allowed — intentional, documented):
+`StripeWebhookController`, `WebhooksController`, `PaymentController`, `RegistrationController`,
+`DataExportController`, `AccountDataExportController`, `DataPurgeController`,
+`SystemInfoController`, `SystemLogsController`, `CompanyHealthController`
+
+If you think you need a new exception, you almost certainly don't. Check the spec first.
+
+---
+
+## Data Access Patterns
+
+### Common Controller Pattern
+
+```csharp
+public class ExampleController : Controller
+{
+    private readonly IUnitOfWork _unitOfWork;
+    private readonly IMapper _mapper;
+
+    public ExampleController(IUnitOfWork unitOfWork, IMapper mapper)
+    {
+        _unitOfWork = unitOfWork;
+        _mapper = mapper;
+    }
+
+    public async Task<IActionResult> Index()
+    {
+        var entities = await _unitOfWork.Examples.GetAllAsync();
+        var dtos = _mapper.Map<List<ExampleDto>>(entities);
+        return View(dtos);
+    }
+
+    [HttpPost]
+    public async Task<IActionResult> Create(CreateExampleDto dto)
+    {
+        var entity = _mapper.Map<Example>(dto);
+        await _unitOfWork.Examples.AddAsync(entity);
+        await _unitOfWork.CompleteAsync();
+        return RedirectToAction(nameof(Index));
+    }
+
+    public async Task<IActionResult> Delete(int id)
+    {
+        await _unitOfWork.Examples.SoftDeleteAsync(id);
+        await _unitOfWork.CompleteAsync();
+        return RedirectToAction(nameof(Index));
+    }
+}
+```
+
+### Using Unit of Work Repositories
+
+All entity repositories are available via `IUnitOfWork` properties:
+- `_unitOfWork.Customers`
+- `_unitOfWork.Jobs`
+- `_unitOfWork.JobItems`
+- `_unitOfWork.Quotes`
+- `_unitOfWork.InventoryItems`
+- `_unitOfWork.Equipment`
+- `_unitOfWork.MaintenanceRecords`
+- Plus additional entities (Suppliers, JobPhotos, JobNotes, etc.)
+
+### Eager Loading Related Data
+
+```csharp
+// Load customer with related data
+var customer = await _unitOfWork.Customers.GetByIdAsync(
+    id,
+    c => c.Jobs,
+    c => c.Quotes,
+    c => c.PricingTier
+);
+
+// Find with predicate and includes
+var activeJobs = await _unitOfWork.Jobs.FindAsync(
+    j => j.Status != JobStatus.Completed,
+    j => j.Customer,
+    j => j.JobItems
+);
+```
+
+### Pagination
+
+```csharp
+var pagedJobs = await _unitOfWork.Jobs.GetPagedAsync(
+    pageNumber: 1,
+    pageSize: 25,
+    j => j.Status == JobStatus.InPreparation,
+    j => j.Customer
+);
+```
+
+## Important Domain Concepts
+
+### Job Lifecycle
+

+```
+
+### Launch Settings (src/PowderCoating.Web/Properties/launchSettings.json)
+
+Default ports:
+- HTTPS: 58461
+- HTTP: 58462
+
+## Authentication & Authorization
+
+### System Roles
+- **SuperAdmin**: Platform-wide access, sees all companies and deleted records
+- **Administrator**: Company admin
+- **Manager**: Operations management
+- **Employee**: Create/edit jobs and quotes
+- **ShopFloor**: Update job status
+- **ReadOnly**: View-only access
+
+### Custom Authorization Policies
+
+Defined in `PowderCoating.Shared/Constants/AppConstants.cs`:
+- `RequireAdministratorRole`
+- `CanManageJobs`
+- `CanManageInventory`
+- `CanManageUsers`
+- `CanViewData`
+
+Apply with `[Authorize(Policy = "PolicyName")]` on controllers/actions.
+
+### JWT Authentication (API Only)
+
+API uses JWT Bearer tokens. Web uses cookie-based Identity authentication.
+
+## AutoMapper Configuration
+
+AutoMapper is registered as singleton in `Program.cs`:
+```csharp
+builder.Services.AddSingleton(provider => new MapperConfiguration(cfg =>
+{
+    cfg.AddMaps(typeof(ApplicationAssemblyMarker).Assembly);
+}).CreateMapper());
+```
+
+All profiles in `Application/Mappings/` are auto-discovered. Profiles include reverse mappings for entity ↔ DTO conversion.
+
+## Logging
+
+Serilog configured to write:
+- Console (structured logs)
+- File: `logs/powdercoating-{Date}.txt` (rolling daily)
+
+Access via constructor injection:
+```csharp
+private readonly ILogger<ExampleController> _logger;
+```
+
+## Common Development Tasks
+
+### Adding a New Entity
+
+1. Create entity class in `Core/Entities/` inheriting from `BaseEntity`
+2. Add DbSet to `ApplicationDbContext`
+3. Register repository property in `IUnitOfWork` interface
+4. Add lazy-loaded property in `UnitOfWork` implementation
+5. Create migration: `dotnet ef migrations add AddEntityName --project ../PowderCoating.Infrastructure`
+6. Apply migration: `dotnet ef database update --project ../PowderCoating.Infrastructure`
+
+### Adding a New Controller
+
+1. Create DTOs in `Application/DTOs/`
+2. Create AutoMapper profile in `Application/Mappings/`
+3. Create controller in `Web/Controllers/`
+4. Create views in `Web/Views/[ControllerName]/`
+5. Add navigation link in `Views/Shared/_Layout.cshtml`
+
+### Working with Soft Deletes
+
+```csharp
+// Soft delete (sets IsDeleted = true)
+await _unitOfWork.Customers.SoftDeleteAsync(id);
+await _unitOfWork.CompleteAsync();
+
+// Physical delete (use sparingly)
+await _unitOfWork.Customers.DeleteAsync(entity);
+await _unitOfWork.CompleteAsync();
+
+// Include deleted records in query
+var allCustomers = await _unitOfWork.Customers.GetAllAsync(ignoreQueryFilters: true);
+```
+
+### Bypassing Multi-Tenancy Filters
+
+Only for SuperAdmin users:
+```csharp
+// See all companies' data
+var allJobs = await _unitOfWork.Jobs.GetAllAsync(ignoreQueryFilters: true);
+```
+
+## Implemented Modules
+
+All modules below are fully implemented with controllers, views, and migrations applied.
+
+### Operations
+- **Jobs** — full lifecycle (16 statuses), worker assignment, time entries, rework tracking, shop access codes, job templates
+- **Quotes** — multi-item pricing engine, AI Photo Quoting (Anthropic Codex Sonnet 4.6), quote-to-job conversion, customer approval portal, online payment
+- **Invoices** — create from job, partial payments, voids, PDF download, email send; 1:1 Job→Invoice enforced by unique index
+- **Deposits** — record against customer/job/quote; auto-applied to invoices on creation; receipt PDF via QuestPDF
+- **Customers** — commercial and non-commercial types, pricing tiers, tax exempt flag + certificate upload, credit limits
+- **Oven Scheduler** — batch jobs into named ovens, capacity planning, suggested batches
+
+### Inventory & Purchasing
+- **Inventory** — stock tracking, transactions, reorder alerts, powder coverage/efficiency fields
+- **Vendors** — supplier management, payment terms, linked to inventory items
+- **Purchase Orders** — create/submit/receive POs, convert to vendor bills
+- **Accounts Payable** — vendor bills, AP ledger, payment tracking
+
+### Shop Management
+- **Shop Workers** — roles (Coater, Sandblaster, etc.), assignment to jobs and maintenance tasks
+- **Equipment & Maintenance** — equipment status lifecycle, scheduled/completed maintenance records
+- **Catalog Items** — pre-priced service catalog with default prices
+- **Pricing Tiers** — customer discount tiers; use `CompanyAdminOnly` policy (not `RequireAdministratorRole`)
+
+### Billing & Payments
+- **Stripe** — subscription plans, checkout sessions, customer portal, webhooks (`/stripe/webhook`)
+- **Stripe Connect** — embedded payments, OAuth flow for tenant onboarding
+- **Twilio SMS** — `ISmsService` fully implemented; webhook at `POST /Webhooks/TwilioSms`
+
+### Platform (SuperAdmin only)
+- **Platform Users** — create/manage SuperAdmin accounts
+- **Companies** — view/manage all tenant companies
+- **Seed Data** — manual seeding via Platform Management UI (not automatic)
+- **Subscription Plans** — `SubscriptionPlanConfig` controls per-plan limits and pricing
+
+### Other
+- **Help Center** — 14 fully-written articles at `Views/Help/`
+- **Setup Wizard** — 10-step onboarding wizard at `SetupWizardController`
+- **Reports** — 24 report actions including P&L, AR Aging, Powder Usage, Job Cycle Time, PDF exports
+- **Gift Certificates** — issue, redeem, track balance
+- **Announcements** — platform-wide announcements to tenants
+
+### Key Pricing Rules
+- Custom powder (no inventory item + `PowderToOrder` > 0): charge for the **full ordered quantity**, not just calculated usage
+- In-stock inventory powder: charge for calculated usage only (surface area × lbs/sqft × unit cost)
+- Tax exempt customers (`Customer.IsTaxExempt`): `TaxPercent` defaults to 0 on quote and invoice create; customer dropdown marks exempt customers with ★
+
+### Pricing Routing Flags — Must Stay In Sync Across All Three Layers
+
+`PricingCalculationService.CalculateQuoteItemPriceAsync` routes each item to the correct pricing path using boolean flags. **These flags MUST exist identically on `QuoteItem`, `JobItem`, and `CreateQuoteItemDto`, AND be mapped in all three `JobItemAssemblyService.CreateJobItem` overloads.**
+
+| Flag | Effect if missing on JobItem |
+|------|------------------------------|
+| `IsAiItem` | Job repriced as calculated item; oven cost double-charged on every save |
+| `IsGenericItem` | ManualUnitPrice ignored; price recalculated from surface area |
+| `IsLaborItem` | Item repriced at surface-area rate instead of hours × labor rate |
+| `IsSalesItem` | ManualUnitPrice ignored; item repriced using coat/surface math |
+
+**Checklist when adding a new pricing routing flag:**
+1. Add the property to `QuoteItem` (Core/Entities)
+2. Add the property to `JobItem` (Core/Entities)
+3. Add it to `CreateQuoteItemDto` (Application/DTOs)
+4. Add it to `JobItemSeed` (private class in JobItemAssemblyService)
+5. Map it in all three `JobItemAssemblyService.CreateJobItem` overloads
+6. Include it in every `existingItemsData` JSON block in job views (`Edit.cshtml`, `EditItems.cshtml`) and in all job controller actions that build `CreateQuoteItemDto` from a `JobItem`
+7. Add a migration if the field is new on a persisted entity
+8. The structural test `PricingRoutingFlags_ExistOnBothQuoteItemAndJobItem` in `JobItemAssemblyServiceTests` will fail until steps 1–3 are done — this is intentional
+
+### Branding
+- Application name: **Powder Coating Logix**
+- PCL logo: `wwwroot/images/pcl-logo.png` — used in sidebar header (when no tenant logo), login/register pages, sidebar footer
+- Sidebar footer always shows PCL logo linking to `http://www.powdercoatinglogix.com`
+- Tenant companies can upload their own logo (stored in Azure Blob `companylogos` container); it replaces the PCL logo in the sidebar header
+
+## Known Issues
+
+- Entity Framework warnings about global query filters on related entities (non-critical, informational only)
+
+## File Upload Configuration
+
+Limits defined in `AppConstants.cs`:
+- Max file size: 10 MB
+- Allowed extensions: jpg, jpeg, png, gif, pdf, doc, docx, xls, xlsx
+
+## Testing Strategy
+
+- **Unit Tests**: Test business logic in isolation
+- **Integration Tests**: Test full request pipeline with test database
+- Use xUnit framework
+- Mock `IUnitOfWork` in unit tests
+
+## Extending the System
+
+### Adding AI Features
+
+AI uses Anthropic Codex Sonnet 4.6 via `IAiQuoteService`. Configure the key under `AI:Anthropic:ApiKey` in `appsettings.json`.
+1. Create service interface in `Application/Interfaces/`
+2. Implement in `Infrastructure/Services/` calling the Anthropic client
+3. Inject into controllers via DI
+
+### SignalR Hubs
+
+Two hubs are already implemented and mapped in `Program.cs`:
+- `NotificationHub` → `/hubs/notifications` (company-scoped push notifications)
+- `ShopHub` → `/hubs/shop` (real-time shop floor updates)
+
+To add a new hub:
+1. Create hub class in `Web/Hubs/`
+2. Map hub in `Program.cs`: `app.MapHub<YourHub>("/hubpath")`
+3. Use JavaScript client in views to connect
+
+### Adding API Endpoints
+
+1. Create controller in `Api/Controllers/` with `[ApiController]` attribute
+2. Return `ActionResult<T>` types
+3. Use `[Authorize]` for protected endpoints
+4. Document with XML comments for Swagger
+
+## Project Dependencies
+
+Key NuGet packages:
+- **AutoMapper 16.0.0**: Entity-to-DTO mapping
+- **Entity Framework Core 8.0.11**: ORM and database access
+- **Serilog.AspNetCore 8.0.3**: Structured logging
+- **Microsoft.AspNetCore.Identity.UI 8.0.11**: Authentication
+- **Swashbuckle.AspNetCore 7.2.0**: API documentation (API project)
+
+## Security Considerations
+
+- Password requirements: 8+ chars, uppercase, lowercase, digit
+- HTTPS enforced in production
+- SQL injection prevented by EF Core parameterization
+- XSS protection via Razor encoding
+- CSRF tokens on all forms (automatic with ASP.NET Core)
+- Sensitive settings (connection strings, API keys) should use User Secrets in development and Azure Key Vault in production
+
+## Active design work
+A visual redesign is in progress. If the user asks about UI changes, dashboard/jobs/board styling, or the new design tokens, read `design_handoff_pcl_redesign/README.md` and follow `design_handoff_pcl_redesign/AGENTS.md` for that work.

+Your job is to generate NCalc expressions that calculate either a fixed price or a surface area
+from user-supplied field values.
+
+CRITICAL: NCalc function names are CASE-SENSITIVE and must be ALL LOWERCASE.
+Supported built-in functions (always write these exactly as shown):
+  if(condition, trueValue, falseValue)   — conditional expression
+  abs(x)                                 — absolute value
+  round(x, digits)                       — round to N decimal places
+  max(a, b)                              — larger of two values
+  min(a, b)                              — smaller of two values
+  pow(base, exponent)                    — exponentiation
+  sqrt(x)                                — square root
+Standard operators: +  -  *  /  %
+Comparison operators: <  >  <=  >=  ==  !=
+Boolean operators: &&  ||  !
+
+Do NOT use: IF, Abs, Round, Max, Min, Pow, Sqrt (uppercase versions) — NCalc will reject them.
+
+The user will describe a custom fabricated item (e.g., 'Roof curb', 'Electrical enclosure',
+'Tubular frame') and you must produce a pricing formula template.
+
+Respond ONLY with a valid JSON object matching this exact schema — no markdown, no explanation:
+
+{
+  ""name"": ""string — short template name (e.g. 'Roof Curb', 'Electrical Enclosure')"",
+  ""outputMode"": ""FixedRate"" | ""SurfaceAreaSqFt"",
+  ""fields"": [
+    {
+      ""name"": ""snake_case_variable_name"",
+      ""label"": ""Human-readable label"",
+      ""unit"": ""in / ft / mm / cm / qty / lbs — or empty string"",
+      ""defaultValue"": number
+    }
+  ],
+  ""formula"": ""NCalc expression using field name variables and optionally 'rate'"",
+  ""defaultRate"": number or null,
+  ""rateLabel"": ""string label for the rate field, e.g. '$/sq ft' — null if no rate"",
+  ""reasoning"": ""1-2 sentences explaining how the formula was derived"",
+  ""verificationInputs"": { ""variable_name"": number },
+  ""verificationResult"": number
+}
+
+Built-in shop-rate variables (injected automatically at eval time — do NOT redeclare them as fields):
+  standard_labor_rate       — shop billing rate in $/hr (e.g.  hours * standard_labor_rate)
+  additional_coat_labor_pct — extra-coat labor surcharge 0–100 (e.g.  cost * (1 + additional_coat_labor_pct/100))
+  markup_pct                — general markup percentage 0–100   (e.g.  cost * (1 + markup_pct/100))
+
+Rules:
+- Use FixedRate when the formula directly calculates a dollar amount (e.g. surface area × rate per sqft)
+- Use SurfaceAreaSqFt when the formula calculates square footage and the standard pricing engine handles the rest
+- Always include a 'rate' variable when outputMode is FixedRate and the price scales with dimensions, UNLESS the formula already uses standard_labor_rate or another built-in
+- Field names must be valid NCalc identifiers (letters, digits, underscores; no spaces or hyphens)
+- Do NOT include standard_labor_rate, additional_coat_labor_pct, or markup_pct in the fields array — they are injected automatically
+- verificationInputs and verificationResult must use the exact field names and formula you generated
+- Surface area formulas for box shapes: 2*(L*W + L*H + W*H) where L/W/H are in the same unit; convert to sqft if needed
+- For inch inputs convert to sqft: divide by 144 (sqin→sqft) or use /12 per side before multiplying
