Why Isolated Worker for CloudZen - -#### ? Requirement 1: .NET 8 Support - -CloudZen targets .NET 8 across all projects. The in-process model **only supports .NET 6**. - -```xml - -net8.0 - - -net8.0 -``` - -#### ? Requirement 2: Security Through Process Isolation - -`SendEmailFunction` and `ChatFunction` handle sensitive API keys (Brevo SMTP, Anthropic). Process isolation provides: -- Better security boundaries -- Isolated memory space -- Reduced attack surface - -```csharp -// Sensitive configuration accessed in isolated process -var smtpKey = _config["BREVO_SMTP_KEY"]; // Email delivery -var aiKey = _config["ANTHROPIC_API_KEY"]; // AI chatbot -``` - -#### ? Requirement 3: Full ASP.NET Core Integration - -CloudZen.Api leverages ASP.NET Core features extensively: - -```csharp -// Security headers via extension methods -req.HttpContext.Response.AddSecurityHeaders(); - -// Client IP extraction for rate limiting -var clientIp = req.GetClientIpAddress(); - -// Full IActionResult support -return new OkObjectResult(new { success = true }); -return new BadRequestObjectResult(new { error = "Invalid" }); -return new ObjectResult(new { error = "Rate limited" }) -{ - StatusCode = StatusCodes.Status429TooManyRequests -}; -``` - -#### ? Requirement 4: Constructor Dependency Injection - -Clean, testable code with proper DI patterns: - -```csharp -public class SendEmailFunction -{ - private readonly ILogger _logger; - private readonly IConfiguration _config; - private readonly IRateLimiterService _rateLimiter; - - public SendEmailFunction( - ILogger logger, - IConfiguration config, - IRateLimiterService rateLimiter) - { - _logger = logger; - _config = config; - _rateLimiter = rateLimiter; - } -} -``` - -#### ? Requirement 5: Custom Services and Middleware - -Rate limiting service registered at startup: - -```csharp -// Api\Program.cs -builder.Services.AddMemoryCache(); -builder.Services.AddSingleton(); -builder.ConfigureFunctionsWebApplication(); -``` - -#### ? Requirement 6: Future-Proof Architecture - -- In-process model ends support **November 2026** -- Isolated worker is Microsoft's **strategic investment** -- New features only added to isolated worker model - ---- - -## Migration Guide (If Starting from In-Process) - -If you encounter legacy in-process Azure Functions code and need to migrate: - -### Step 1: Update Project File - -```xml - - - - net6.0 - V4 - - - - - - - - - - net8.0 - V4 - Exe - enable - enable - - - - - - - - -``` - -### Step 2: Update Namespaces - -```csharp -// BEFORE: In-Process -using Microsoft.Azure.WebJobs; -using Microsoft.Azure.WebJobs.Extensions.Http; - -// AFTER: Isolated Worker -using Microsoft.Azure.Functions.Worker; -``` - -### Step 3: Update Function Attributes - -```csharp -// BEFORE: In-Process -[FunctionName("SendEmail")] -public static async Task Run(...) - -// AFTER: Isolated Worker -[Function("SendEmail")] -public async Task Run(...) -``` - -### Step 4: Create Program.cs - -```csharp -// New file: Api\Program.cs -using Microsoft.Azure.Functions.Worker; -using Microsoft.Azure.Functions.Worker.Builder; -using Microsoft.Extensions.DependencyInjection; -using Microsoft.Extensions.Hosting; - -var builder = FunctionsApplication.CreateBuilder(args); - -builder.ConfigureFunctionsWebApplication(); - -// Register your services -builder.Services.AddSingleton(); - -var host = builder.Build(); -host.Run(); -``` - -### Step 5: Convert Static Classes to Instance Classes - -```csharp -// BEFORE: In-Process (static) -public static class MyFunction -{ - [FunctionName("MyFunction")] - public static async Task Run( - [HttpTrigger(...)] HttpRequest req, - ILogger log) - { - // Use log parameter - } -} - -// AFTER: Isolated Worker (instance) -public class MyFunction -{ - private readonly ILogger _logger; - - public MyFunction(ILogger logger) - { - _logger = logger; - } - - [Function("MyFunction")] - public async Task Run( - [HttpTrigger(...)] HttpRequest req) - { - // Use _logger field - } -} -``` - -### Step 6: Update host.json - -```json -{ - "version": "2.0", - "logging": { - "applicationInsights": { - "samplingSettings": { - "isEnabled": true, - "excludedTypes": "Request" - }, - "enableLiveMetricsFilters": true - } - } -} -``` - ---- - -## Troubleshooting - -### Error: "Microsoft.Azure.Functions.Worker not found" - -**Symptoms:** -``` -CS0234: The type or namespace name 'Azure' does not exist in the namespace 'Microsoft' -``` - -**Cause:** Corrupted build artifacts or packages not restored. - -**Solution:** -```powershell -# Clean build artifacts -Remove-Item -Recurse -Force Api\obj, Api\bin -ErrorAction SilentlyContinue - -# Restore packages -dotnet restore Api\CloudZen.Api.csproj - -# Rebuild -dotnet build Api\CloudZen.Api.csproj -``` - -### Error: Blazor Project Including Api Files - -**Symptoms:** -``` -CS0234: The type or namespace name 'Azure' does not exist in the namespace 'Microsoft' -``` -(Error appears when building CloudZen.csproj, not CloudZen.Api.csproj) - -**Cause:** Default glob patterns in Blazor project include all subfolders. - -**Solution:** Add exclusion to `CloudZen.csproj`: -```xml - - $(DefaultItemExcludes);Api\** - -``` - -### Error: Duplicate Assembly Attributes - -**Symptoms:** -``` -CS0579: Duplicate 'System.Reflection.AssemblyCompanyAttribute' attribute -``` - -**Cause:** Corrupted obj folders with stale generated files. - -**Solution:** -```powershell -# Remove all build artifacts -Remove-Item -Recurse -Force obj, bin -ErrorAction SilentlyContinue -Remove-Item -Recurse -Force Api\obj, Api\bin -ErrorAction SilentlyContinue - -# Restore and rebuild -dotnet restore CloudZen.sln -dotnet build CloudZen.sln -``` - -### Error: Function Not Found at Runtime - -**Symptoms:** Function deploys but returns 404. - -**Cause:** Missing `host.json` or incorrect route configuration. - -**Solution:** Verify `Api\host.json` exists: -```json -{ - "version": "2.0", - "extensions": { - "http": { - "routePrefix": "api" - } - } -} -``` - -### Error: Cold Start Taking Too Long - -**Symptoms:** First request takes 10+ seconds. - -**Cause:** Isolated worker has inherently longer cold starts due to process initialization. - -**Solutions:** -1.

The .NET isolated worker SDK generates a `.azurefunctions` folder during `dotnet publish` that the Azure Functions runtime requires to discover functions. When this folder is silently excluded from the uploaded artifact, the deploy job pushes an incomplete package to Azure. - -**The failure chain:** -``` -dotnet publish → ✅ .azurefunctions/ generated in ./output -upload-artifact@v4 → ❌ .azurefunctions/ silently excluded (hidden folder) -download-artifact → artifact missing .azurefunctions/ -deploy to Azure → incomplete package deployed -Azure Functions host → "0 functions found" → all routes return 404 -``` - -### Resolution -Add `include-hidden-files: true` to the `upload-artifact@v4` step in `.github/workflows/azure-functions.yml`: - -```yaml -- name: Upload build artifact - uses: actions/upload-artifact@v4 - with: - name: function-app - path: ./output - include-hidden-files: true # Required for .azurefunctions folder -``` - -### Related Issues That Can Cause the Same Symptom -These were also fixed during the same investigation: - -1. **Invalid JSON comments in `host.json`** — JSON does not support `//` comments. If `host.json` contains `//` commented-out blocks, the Azure Functions host fails to parse it, preventing function discovery. Visual Studio's editor tolerates JSONC, but the Azure runtime does not. - -2. **Worker process crash on startup due to missing CORS config** — If neither `AllowedOrigins` nor `ProductionOrigin` environment variables are set in Azure App Settings, the `Program.cs` CORS configuration throws an `InvalidOperationException`, crashing the worker process before it can report its functions. The fix was to add `ProductionOrigin` as a fallback before throwing: - ```csharp - // Priority: AllowedOrigins → ProductionOrigin → Dev defaults → throw - if (configuredOrigins is not null && configuredOrigins.Length > 0) - allowedOrigins = configuredOrigins; - else if (!string.IsNullOrEmpty(productionOrigin)) - allowedOrigins = [productionOrigin]; - else if (isDevelopment) - allowedOrigins = new[] { "https://localhost:7243", "http://localhost:5054" }; - else - throw new InvalidOperationException("CORS 'AllowedOrigins' or 'ProductionOrigin' must be configured."); - ``` - -### Verification -After deploying, confirm in **Azure Portal > Function App > Functions** that both `Chat` and `SendEmail` appear, or check Log Stream for: -``` -2 functions found (Custom) -2 functions loaded -``` - ---- - -## Quick Reference: Development URLs - -| Component | Default URL | -|-----------|-------------| -| Blazor App (IIS Express) | `https://localhost:44370` | -| Blazor App (Kestrel) | `https://localhost:5001` | -| Azure Function | `http://localhost:7071` or `http://localhost:7257` | -| Azurite Blob | `http://127.0.0.1:10000` | -| Azurite Queue | `http://127.0.0.1:10001` | -| Azurite Table | `http://127.0.0.1:10002` | - ---- - -## Quick Reference: Key Files - -| Purpose | File Path | -|---------|-----------| -| Azure Function Config | `Api/local.settings.json` | -| Azure Function Host Config | `Api/host.json` | -| Blazor Dev Config | `wwwroot/appsettings.Development.json` | -| Blazor Prod Config | `wwwroot/appsettings.json` | -| CORS Settings | `Api/Security/InputValidator.cs` | -| Email Function | `Api/Functions/SendEmailFunction.cs` | -| Chat Function | `Api/Functions/ChatFunction.cs` | -| Email Service (Blazor) | `Services/ApiEmailService.cs` | -| CI/CD Workflow | `.github/workflows/azure-functions.yml` | - ---- - -*Last Updated: March 2026* diff --git a/docs/01-architecture/API_ENDPOINTS.md b/docs/01-architecture/API_ENDPOINTS.md new file mode 100644 index 0000000..8e4a0b3 --- /dev/null +++ b/docs/01-architecture/API_ENDPOINTS.md @@ -0,0 +1,210 @@ +# API Endpoints Reference + +All endpoints are Azure Functions (Isolated Worker, .NET 8) behind `/api/`.

Overview + +The CloudZen AI Chatbot is a website-embedded conversational assistant that answers visitor questions about CloudZen's services, process, and portfolio. It converts visitors into leads by guiding them toward booking a free consultation, while protecting against abuse with multi-layered rate limiting, input validation, and conversation caps. + +The chatbot uses Anthropic Claude as the AI backend. All API communication is proxied through Azure Functions so that the API key and knowledge base are never exposed to the browser. It is **not** a general-purpose AI assistant -- it is scoped exclusively to CloudZen's business context. + +### Key Design Principles + +| Principle | Implementation | +|---|---| +| **Security first** | API key stays server-side; knowledge base never sent to client | +| **Cost control** | Capped tokens, capped messages, capped reply length, conversation history trimming | +| **Lead conversion** | 5-question limit then CTA to book consultation; system prompt always redirects to outreach | +| **Jargon-free** | System prompt enforces plain English, 1-2 sentence responses | +| **Abuse resistant** | Per-IP rate limiting, input validation, off-topic rejection via prompt | + +--- + +## 2.

It is scoped exclusively to CloudZen's business context and trained via a server-side knowledge base that is never exposed to the client. - -### Key Design Principles - -| Principle | Implementation | -|---|---| -| **Security first** | API key stays server-side; knowledge base never sent to client | -| **Cost control** | Capped tokens, capped messages, capped reply length, conversation history trimming | -| **Lead conversion** | 5-question limit → CTA to book consultation; system prompt always redirects to outreach | -| **Jargon-free** | System prompt enforces plain English, 1-2 sentence responses | -| **Abuse resistant** | Per-IP rate limiting, input validation, off-topic rejection via prompt | - ---- - -## 2.

Anti-Over-Engineering Rules + +### MUST NOT in MVP Phase + +- ❌ **Generic repositories** — Use specific repositories per aggregate. Don't build `IRepository` until you have 5+ entities with identical patterns. +- ❌ **CQRS read models** — Use the same EF model for reads and writes until query performance proves otherwise. +- ❌ **Event sourcing** — Use simple database updates. Event sourcing is v2+ complexity. +- ❌ **Microservices** — Start as a modular monolith. Extract services only when you have a proven scaling bottleneck. +- ❌ **Message queues** — Use direct method calls. Add MediatR notifications for in-process events. Queues come when you need cross-service communication. +- ❌ **Custom middleware** — Use built-in ASP.NET middleware. Write custom only when built-in can't solve the problem. +- ❌ **Abstract factories** — Inject services directly. Factory pattern when you have 3+ implementations to choose from at runtime. +- ❌ **Specification pattern** — Use LINQ Where clauses. Specifications when you have 5+ reusable query filters. +- ❌ **Custom result types** — Use `IActionResult` or simple exceptions. Result when error handling becomes a pattern. +- ❌ **GraphQL** — Use REST. GraphQL when you have 10+ clients with different data needs. + +### MUST DO in MVP Phase + +- ✅ **Clean Architecture layers** — Separation of concerns is free and prevents rewrites. +- ✅ **Interfaces for external services** — `IPaymentService` so you can swap providers later. +- ✅ **Input validation** — FluentValidation on every command. Non-negotiable. +- ✅ **Authentication & authorization** — `[Authorize]` on every endpoint. Default deny. +- ✅ **One happy-path test per feature** — Minimum viable test coverage. +- ✅ **Code-behind pattern** — `.razor` + `.razor.cs` from day one. Costs nothing, prevents technical debt. +- ✅ **Parameterized queries** — Never concatenate SQL. Ever. +- ✅ **Structured logging** — `ILogger` with structured parameters. Costs nothing, saves debugging time. +- ✅ **Dependency injection** — Always. No `new SomeService()` in business logic. + +## 5.

This gives AI models immediate structured context: - -```markdown -## Quick Reference - -| Item | Value | -|------|-------| -| **Endpoint** | `POST /api/example` | -| **Frontend Component** | `Features/X/Components/Main.razor` | -| **Backend Function** | `Api/Features/X/ExampleFunction.cs` | -| **Key Integration** | [external service or pattern] | -| **Entry Point** | [how users reach this feature] | -``` - -### Rule 5: Heading Hierarchy - -- Use H1 (`#`) only once — the document title -- Use H2 (`##`) for major sections -- Use H3 (`###`) for subsections -- Never skip levels (no H2 → H4) -- **No emoji** in headings — they cause parsing inconsistencies across models - -### Rule 6: Structured Data - -Prefer tables over prose for factual/reference information: - -- Configuration settings → table -- Component listings → table -- API fields → table with Type, Required, Constraints columns -- Error handling → table with Error, User Message, HTTP Status columns -- Constants → table with Name, Value, Description columns - -### Rule 7: Code Blocks - -Always specify the language in fenced code blocks for syntax highlighting: - -```csharp -// Good -public async Task DoSomething() { } -``` - -```json -{ "key": "value" } -``` - -### Rule 8: Cross-References - -Every cross-reference must include a brief description of what the linked document adds: - -```markdown -- [`API_ENDPOINTS.md`](../01-architecture/API_ENDPOINTS.md) — Full endpoint specification with request/response schemas -- [`02_ui_color_design_system.md`](../06-patterns/02_ui_color_design_system.md) — Sidebar and component color usage -``` - -Never use bare links without context. - -### Rule 9: Self-Contained Content - -Each document must be understandable without reading other documents. This means: -- Define acronyms on first use -- Include enough context to understand the feature independently -- Cross-reference for depth, but don't require it for comprehension - -### Rule 10: ASCII-Safe Content - -For maximum compatibility across AI model tokenizers: -- Use ASCII arrows (`->`, `-->`) instead of Unicode (`→`, `⟶`) -- Use ASCII dashes (`--`) instead of em-dashes (`—`) -- Use `[x]` and `[ ]` instead of `✅` and `❌` in tables -- Replace `•` bullets with `-` -- Avoid decorative emoji entirely - -### Rule 11: File Naming - -Files in `docs/` subdirectories follow numbered prefix convention: -``` -XX_CATEGORY_NAME.md -``` -Examples: `01_FEATURE_CONTACT_FORM.md`, `02_FEATURE_APPOINTMENT_SYSTEM.md` - -### Rule 12: Directory Index - -Each `docs/` subdirectory MUST have a `README.md` that: -- Has its own metadata block -- Lists all documents in the directory with a summary table -- Includes cross-references to related directories - ---- - -## Verification Checklist - -After applying the pattern, verify: - -- [ ] Metadata block is the first content in the file -- [ ] Scope boundaries are stated (what's NOT covered) -- [ ] Table of Contents is present (if 3+ sections) -- [ ] Quick Reference table exists (for feature docs) -- [ ] No emoji in headings -- [ ] All code blocks have language specifiers -- [ ] Cross-references include descriptions -- [ ] Structured data uses tables, not prose -- [ ] Heading hierarchy is correct (H1 > H2 > H3, no skips) -- [ ] ASCII-safe characters used throughout -- [ ] Last Updated date is current -- [ ] Parent README.md index is updated (if new doc) - ---- - -## Template for New Feature Documentation - -```markdown -> **Document**: [Feature Name] -> **Scope**: [What this doc covers] -> **Audience**: AI assistants, developers -> **Last Updated**: [Month Year] - -# [Feature Name] - -## Table of Contents - -1.

Failure modes are enumerated. Steady state is quantified. + +### Step 2 — Design the Experiment + +Create a formal experiment with hypothesis, method, and abort criteria. + +1. **State the hypothesis** — "When the payment gateway returns 503 for 30 seconds, the order service queues payments and retries successfully after recovery, with zero data loss." +2. **Define blast radius** — Scope the experiment: single pod, single AZ, single service, or broader. +3. **Set abort criteria** — Define conditions that immediately stop the experiment: error rate > 5%, data inconsistency detected, customer-facing impact. +4. **Plan observation** — Identify which dashboards, metrics, and logs to watch during the experiment. +5. **Document rollback** — Step-by-step procedure to restore normal operation if the experiment goes wrong. + +**✅ Validation checkpoint:** Experiment document is reviewed and approved. Abort criteria are automated where possible. + +### Step 3 — Prepare the Environment + +Set up the infrastructure for safe chaos injection. + +1. **Choose the tool** — Select the appropriate chaos tool for the failure type (see reference guide). +2. **Configure injection scope** — Target specific services, pods, or network paths — never inject chaos broadly without controls. +3. **Verify monitoring** — Confirm dashboards and alerts are operational and can detect the injected failure. +4. **Notify stakeholders** — Ensure the team knows an experiment is running and when to expect it. +5. **Prepare rollback automation** — Script the rollback so it can be executed in under 60 seconds. + +**✅ Validation checkpoint:** Tool is configured. Monitoring is verified. Team is notified. Rollback is tested. + +### Step 4 — Execute and Observe + +Run the experiment with disciplined observation. + +1. **Record baseline** — Capture steady-state metrics immediately before injection. +2. **Inject the failure** — Start the chaos experiment with the defined parameters. +3. **Observe continuously** — Watch dashboards, logs, and traces in real time. Note any unexpected behavior. +4. **Check abort criteria** — Continuously evaluate whether abort conditions are met. +5. **Stop injection** — After the planned duration, remove the failure condition. +6. **Monitor recovery** — Observe how long the system takes to return to steady state. + +**✅ Validation checkpoint:** Experiment ran to completion (or was aborted safely). Observations are documented. + +### Step 5 — Analyze and Harden + +Turn findings into resilience improvements. + +1. **Compare hypothesis vs. reality** — Did the system behave as expected?

Stating the Obvious + +The most common anti-pattern — comments that add zero information. + +```csharp +// ❌ ANTI-PATTERN: Restating the code +var order = await repository.GetByIdAsync(orderId); // Get order by ID +customer.Name = request.Name; // Set customer name +if (order == null) return NotFound(); // Return not found if null +count++; // Increment count +var total = items.Sum(i => i.Price); // Calculate total price + +// ✅ No comment needed — the code is self-explanatory +var order = await repository.GetByIdAsync(orderId); +customer.Name = request.Name; +if (order is null) return NotFound(); +``` + +### 2. Journal Comments + +Comments tracking change history — that's what git is for. + +```csharp +// ❌ ANTI-PATTERN: Change log in code +// 2024-01-15: Added validation for negative amounts (John) +// 2024-02-01: Fixed bug where zero amount was allowed (Jane) +// 2024-03-10: Added currency validation (John) +public Result Validate(Money amount) { } + +// ✅ Use git blame / git log for history +``` + +### 3. Commented-Out Code + +Dead code disguised as comments — creates confusion about intent. + +```csharp +// ❌ ANTI-PATTERN: Commented-out code +public async Task ProcessAsync() +{ + // var oldResult = await _legacyService.ProcessAsync(); + // if (oldResult.IsFailure) + // await _fallback.HandleAsync(oldResult.Error); + var result = await _newService.ProcessAsync(); +} + +// ✅ Delete it — git has the history if you need it back +public async Task ProcessAsync() +{ + var result = await _newService.ProcessAsync(); +} +``` + +### 4. Noise Comments + +Comments required by misguided coding standards. + +```csharp +// ❌ ANTI-PATTERN: Noise on every member +/// +/// Gets or sets the name. +/// +public string Name { get; set; } + +/// +/// Default constructor. +/// +public Customer() { } + +// ✅ Skip docs on self-explanatory members +// Only document when there's non-obvious behavior: +/// +/// Gets the customer's display name, falling back to email prefix when name is empty. +/// +public string DisplayName => string.IsNullOrWhiteSpace(Name) + ? Email.Split('@')[0] + : Name; +``` + +### 5. Misleading Comments + +Comments that don't match the actual code behavior. + +```csharp +// ❌ ANTI-PATTERN: Comment says one thing, code does another +// Returns null if not found +public Order GetOrder(int id) => + _orders.First(o => o.Id == id); // Actually throws if not found! + +// ✅ Comment and code must agree +/// Order does not exist. +public Order GetOrder(int id) => + _orders.FirstOrDefault(o => o.Id == id) + ?? throw new NotFoundException(nameof(Order), id); +``` + +### 6. TODO Comments That Never Get Done + +```csharp +// ❌ ANTI-PATTERN: Stale TODOs +// TODO: Add validation (added 2 years ago) +// HACK: Temporary fix for performance (been here 18 months) +// FIXME: This breaks when amount is zero + +// ✅ Create a tracked issue instead +// If a TODO is truly needed short-term: +// TODO(#1234): Switch to batch processing after PaymentGateway v3 migration +``` + +## When Comments ARE Valuable + +### Business Rules Not Obvious from Code +```csharp +// Escrow funds held for 24h after buyer confirmation (regulatory requirement, SEC Rule 15c3-3) +await HoldFundsAsync(order, TimeSpan.FromHours(24), ct); + +// Fees waived for transactions under $10 per marketing promotion Q1-2025 +if (amount < Money.USD(10)) return Money.Zero("USD"); +``` + +### Workarounds with References +```csharp +// Workaround for EF Core bug #28571 — GroupBy with nullable navigation +// Remove after upgrading to EF Core 9.x +var results = await _context.Escrows + .Where(e => e.Status != null) + .GroupBy(e => e.Status!) + .ToListAsync(ct); +``` + +### Performance Justifications +```csharp +// Using compiled regex — this runs in hot path (~10K invocations/sec) +private static readonly Regex EmailPattern = + new(@"^[^@\s]+@[^@\s]+\.[^@\s]+$", RegexOptions.Compiled); + +// Pre-allocate to avoid list resizing — typical batch is 500-1000 items +var results = new List(capacity: 1024); +``` + +### Complex Algorithm Intent +```csharp +// Two-phase commit: first reserve funds in payment gateway, +// then persist order state. If persistence fails, release the reservation. +// This prevents orphaned fund holds. +``` + +## Review Checklist + +When reviewing comments, ask: +1. Does this comment add information not available from the code? +2. Could the code be rewritten to eliminate the need for this comment? +3. Is the comment accurate (matches what the code actually does)? +4. Is this a stale TODO that should be a tracked issue? +5. Is this commented-out code that should be deleted? diff --git a/.github/skills/code-documenter/references/jsdoc-tsdoc.md b/.github/skills/code-documenter/references/jsdoc-tsdoc.md new file mode 100644 index 0000000..c97772e --- /dev/null +++ b/.github/skills/code-documenter/references/jsdoc-tsdoc.md @@ -0,0 +1,161 @@ +# JSDoc / TSDoc Reference + +Guide for generating JavaScript and TypeScript documentation comments. + +## TSDoc Standard (TypeScript) + +### Function Documentation +```typescript +/** + * Calculates the order fee based on transaction amount and order type. + * + * @param amount - The transaction amount in the specified currency. + * @param orderType - The type of order determining the fee schedule. + * @returns The calculated fee as a Money value object. + * @throws {@link InvalidAmountError} When amount is negative or zero. + * + * @example + * ```ts + * const fee = calculateEscrowFee(Money.usd(1000), EscrowType.Standard);

architectural layers are affected. + +1. **Identify the domain concept** — Map the requirement to domain entities, value objects, and aggregates. +2. **Determine the slice** — Is this a new vertical slice (command + handler + validator + endpoint) or a cross-cutting change? +3. **Check existing patterns** — Scan the codebase for similar features to maintain consistency. +4. **Plan the layers** — Identify which layers need changes: Domain, Application, Infrastructure, Presentation. + +**✅ Checkpoint: Domain concepts identified, slice type determined, affected layers mapped before writing code.** + +### Step 2 — Implement Domain and Application Layers + +Build the core business logic following DDD and CQRS patterns. + +1. **Domain entities** — Create or update entities with rich behavior, value objects, and domain events. +2. **Command/Query records** — Define `IRequest` records with descriptive names. +3. **Handlers** — Implement `IRequestHandler` with single-responsibility logic. +4. **Validators** — Create FluentValidation validators for all commands. +5. **Pipeline behaviors** — Leverage existing `ValidationBehavior<,>`, `LoggingBehavior<,>` via MediatR pipeline. + +**✅ Checkpoint: Domain model compiles, handler logic is testable in isolation, validators cover all inputs.** + +### Step 3 — Implement Infrastructure Layer + +Wire up data access, external services, and cross-cutting concerns. + +1. **EF Core configuration** — Add entity configurations with `IEntityTypeConfiguration`. +2. **Repository implementation** — Implement repository interfaces defined in the Application layer. +3. **Migrations** — Create and test EF Core migrations for schema changes. +4. **External services** — Implement adapters for third-party APIs with Polly resilience policies. + +**✅ Checkpoint: Migrations apply cleanly, repository queries are efficient (check with SQL logging), external calls have retry policies.** + +### Step 4 — Implement Presentation Layer + +Expose the feature through minimal API endpoints. + +1. **Define endpoints** — Create typed endpoint classes using `IEndpointRouteBuilder` extensions. +2. **Map routes** — Use `app.MapGet/Post/Put/Delete` with route groups for versioning. +3. **Add authorization** — Apply `[Authorize(Policy = "...")]` or `.RequireAuthorization()` on endpoints. +4. **Configure serialization** — Use `TypedResults` for compile-time response type checking. +5. **Add OpenAPI metadata** — Use `.WithName()`, `.Produces()`, `.WithTags()` for Swagger docs. + +**✅ Checkpoint: Endpoints respond correctly, authorization enforced, Swagger shows correct schemas.** + +### Step 5 — Test and Validate + +Verify correctness across all layers. + +1. **Unit tests** — Test handlers, validators, and domain logic in isolation with mocked dependencies. +2. **Integration tests** — Use `WebApplicationFactory` with test database for end-to-end endpoint testing. +3. **Build verification** — Run `dotnet build` with `TreatWarningsAsErrors` and `dotnet test` with coverage. +4. **AOT compatibility** — Verify trimming warnings are resolved if targeting Native AOT. + +**✅ Checkpoint: All tests pass, no build warnings, coverage meets team threshold.** + +## Quick Reference + +### Vertical Slice — Command + Handler + Endpoint + +```csharp +// Application/Features/Escrows/CreateEscrow/CreateOrderCommand.cs

`AsNoTracking()` for all read-only queries +- Apply Polly resilience policies on all external HTTP calls + +### MUST NOT + +- Do not inject `IConfiguration` directly into services — use `IOptions` pattern +- Do not put business logic in controllers or endpoints — delegate to MediatR handlers +- Do not use `DbContext` directly in handlers — access through repository interfaces +- Do not hardcode connection strings or secrets — use `dotnet user-secrets` or Key Vault +- Do not skip migrations — every schema change must have a corresponding migration +- Do not use `async void` — always return

to be someone or something else? + +### Threats by Component + +| Component | Threat | Example | +|-----------|--------|---------| +| API Endpoint | Identity spoofing | Forged JWT tokens, stolen session cookies | +| External Service | Service impersonation | DNS hijacking redirecting API calls | +| Message Queue | Origin spoofing | Unauthorized publisher sends malicious messages | +| Database | Connection spoofing | Attacker connects with stolen credentials | +| SignalR Hub | Circuit hijacking | Reconnecting to another user's Blazor circuit | + +### Detection Questions +- [ ] Is every endpoint protected with authentication? +- [ ] Are JWT tokens validated for issuer, audience, expiry, and signing key? +- [ ] Is mutual TLS used for service-to-service communication? +- [ ] Are message queue publishers authenticated? +- [ ] Is session fixation prevented (new session ID after login)? + +### Mitigations +- **Entra ID / OIDC** for interactive authentication +- **Managed Identity** for Azure service-to-service +- **Mutual TLS** for critical internal services +- **Message signing** (HMAC) for queue-based communication +- **Certificate pinning** for external payment gateway calls + +## T — Tampering (Integrity Threats) + +**Core Question:** Can an attacker modify data in transit or at rest? + +### Threats by Component + +| Component | Threat | Example | +|-----------|--------|---------| +| HTTP Request | Parameter manipulation | Changing order amount in POST body | +| Database | Data modification | SQL injection modifying order records | +| Config Files | Config tampering | Modified connection strings or feature flags | +| Log Files | Log manipulation | Attacker erasing evidence of access | +| API Response | Response injection | MITM modifying API response data | + +### Detection Questions +- [ ] Is all data in transit encrypted with TLS 1.2+? +- [ ] Is input validation enforced server-side (not just client)? +- [ ] Are critical database operations logged in immutable audit trail? +- [ ] Are configuration files integrity-checked? +- [ ] Is anti-forgery (CSRF) protection enabled on state-changing endpoints? + +### Mitigations +- **TLS

**EF Core parameterized queries** — never concatenate SQL + +## R — Repudiation (Accountability Threats) + +**Core Question:** Can a user deny performing an action? + +### Key Scenarios for Escrow Platform +- Buyer denies initiating an order transaction +- Seller denies confirming delivery +- Admin denies modifying order terms +- User denies authorizing a fund release + +### Mitigations +- **Structured audit logging** with user identity, timestamp, IP, correlation ID +- **Tamper-proof log storage** (Azure Monitor, immutable blob, or append-only DB) +- **Digital signatures** on order

access data they shouldn't see? + +### Threats by Component + +| Component | Threat | Example | +|-----------|--------|---------| +| API Response | Data leakage | Stack traces in error responses | +| Database | Data exposure | SQL injection extracting user records | +| Logs | PII in logs | Passwords, tokens, SSNs in log files | +| Client Storage | Client exposure | Sensitive data in localStorage | +| Config Files | Secret exposure | API keys in committed `appsettings.json` | +| HTTP Headers | Server info | `Server: Kestrel`, `X-Powered-By: ASP.NET` | + +### Mitigations +- **Data classification** — label data as Public/Internal/Confidential/Restricted +- **Encrypt at rest** — TDE for SQL, Data Protection API for fields +- **Sanitize errors** — generic messages in production +- **Never log secrets/PII** — use structured logging with redaction +- **Remove server headers** — strip `Server`, `X-Powered-By` +- **Classify and control** — access controls per data classification + +## D — Denial of Service (Availability Threats) + +**Core Question:** Can an attacker make the system unavailable? + +### Mitigations +- **Rate limiting** (`AddRateLimiter` in ASP.NET Core 7+) +- **Request size limits** (`MaxRequestBodySize`, file upload limits) +- **Query pagination** — never `ToListAsync()` unbounded +- **Circuit breakers** (Polly) on external service calls +- **Timeout policies** on all async operations +- **Bulkhead isolation** for critical vs. non-critical paths +- **Auto-scaling** with health probes + +## E — Elevation of Privilege (Authorization Threats) + +**Core Question:** Can an attacker gain higher privileges than intended? + +### Mitigations +- **Policy-based authorization** — `[Authorize(Policy = "EscrowAdmin")]` +- **Resource-based auth** — verify ownership before access +- **IDOR prevention** — use GUIDs, filter by authenticated user +- **Safe deserialization** — no `BinaryFormatter`, no `TypeNameHandling.All` +- **Path validation** —

CloudZen helps small and medium-sized businesses modernize their technology. " + + "We build custom systems, migrate to the cloud, automate workflows, and create data dashboards — " + + "so you can focus on growing your business instead of wrestling with outdated tools.

"); + }), + + new("How does the Build & Grow model work?", builder => + { + builder.AddMarkupContent(0, + "

Our process has three simple stages:

" + + "
    " + + "
  1. Discover — We learn about your business, goals, and pain points in a free consultation.
    2. " + + "
  2. Build — We design and develop your solution in short stages, with weekly check-ins so you see progress every step of the way.
    3. " + + "
  3. Launch & Grow — We deploy, train your team, and provide ongoing support as your business evolves.
    4. " + + "
"); + }), + + new("How much do your services cost?", builder => + { + builder.AddMarkupContent(0, + "

We use a flat-fee project model — no hourly surprises. After your free consultation, " + + "we provide a clear proposal with a fixed price based on your project scope. " + + "The initial consultation is always free with no obligation.

"); + }), + + new("How do I get started?", builder => + { + builder.AddMarkupContent(0, + "

Easy — book a free 30-minute consultation. " + + "We'll discuss your needs, answer your questions, and outline how we can help. " + + "No commitment required. You can also email us at " + + "info@cloud-zen.net " + + "and we'll respond within 24 hours.

"); + }), + + new("What technologies do you use?", builder => + { + builder.AddMarkupContent(0, + "

We work with modern, proven technologies including .NET, Blazor, Azure cloud services, " + + "PostgreSQL, and AI-powered tools. But we're technology-agnostic — we choose the best tools " + + "for your specific needs, not the other way around.

"); + }), + + new("How long do projects typically take?", builder => + { + builder.AddMarkupContent(0, + "

Timelines depend on scope, but most projects follow our staged approach:

" + + "
    " + + "
  • Small automation or dashboard — 2 to 4 weeks
    • " + + "
  • System modernization — 1 to 3 months
    • " + + "
  • Full custom platform — 3 to 6 months
    • " + + "
" + + "

We break every project into short stages so you see progress weekly — no disappearing for months.

"); + }), + + new("Do you offer ongoing support after launch?", builder => + { + builder.AddMarkupContent(0, + "

Yes. We don't build and vanish. After launch, we offer ongoing support and maintenance to keep " + + "your system running smoothly. We can also iterate on your solution as your business grows and needs evolve.

"); + }), + + new("What industries do you work with?", builder => + { + builder.AddMarkupContent(0, + "

We work across industries — our focus is on small and medium businesses that need " + + "better technology without the overhead of a full IT department. We've helped companies in professional services, " + + "logistics, healthcare administration, retail operations, and more.

"); + }), + + new("Is my data secure?", builder => + { + builder.AddMarkupContent(0, + "

We take security seriously. Our website uses HTTPS encryption, strict security headers, and " + + "all secrets are managed through Azure Key Vault. We follow industry best practices for input validation, " + + "rate limiting, and data protection. For full details, see our " + + "Privacy Policy.

"); + }), + + new("What if I'm not sure what I need?", builder => + { + builder.AddMarkupContent(0, + "

That's exactly what the free consultation is for. Many of our clients start with a vague feeling that " + + "\"things could be better\" — and we help them identify specific improvements that will have the biggest " + + "impact. No jargon, no pressure. Just a conversation about your goals.
