feat: Document completed tasks across multiple components

- Added completed tasks documentation for Scheduler WebService, ImpactIndex, Models, Queue, Storage.Mongo, Worker, Signals, Signer, UI, Zastava.Observer, Zastava.Webhook, Zastava.Core, Cryptography.Kms, Cryptography, and Plugin. - Each task includes ID, status, owners, dependencies, descriptions, and exit criteria to ensure clarity and traceability. - Enhanced integration and unit testing coverage across various components to validate functionality and compliance with specifications.

+# Aggregation-Only Guard Library Reference

+> **Related tasks:** `WEB-AOC-19-001`, `WEB-AOC-19-003`, `DEVOPS-AOC-19-001`

+
+The Aggregation-Only Contract (AOC) guard library enforces the canonical ingestion
+rules described in `docs/ingestion/aggregation-only-contract.md`. Service owners
+should use the guard whenever raw advisory or VEX payloads are accepted so that
+forbidden fields are rejected long before they reach MongoDB.
+
+## Packages
+
+### `StellaOps.Aoc`
+- `IAocGuard` / `AocWriteGuard` — validate JSON payloads and emit `AocGuardResult`.
+- `AocGuardOptions` — toggles for signature enforcement, tenant requirements, and required top-level fields.
+- `AocViolation` / `AocViolationCode` — structured violations surfaced to callers.
+- `ServiceCollectionExtensions.AddAocGuard()` — DI helper that registers the singleton guard.
+- `AocGuardExtensions.ValidateOrThrow()` — throws `AocGuardException` when validation fails.
+
+### `StellaOps.Aoc.AspNetCore`
+- `AocGuardEndpointFilter<TRequest>` — Minimal API endpoint filter that evaluates request payloads through the guard before invoking handlers.
+- `AocHttpResults.Problem()` — Produces a RFC 7807 payload that includes violation codes, suitable for API responses.
+
+## Minimal API integration
+
+```csharp
+using StellaOps.Aoc;
+using StellaOps.Aoc.AspNetCore.Routing;
+using StellaOps.Aoc.AspNetCore.Results;
+
+var builder = WebApplication.CreateBuilder(args);
+
+builder.Services.AddAocGuard();
+builder.Services.Configure<AocGuardOptions>(options =>
+{
+    options.RequireSignatureMetadata = true;
+    options.RequireTenant = true;
+});
+
+var app = builder.Build();
+
+app.MapPost("/ingest", async (IngestionRequest request, IAocGuard guard, ILogger<Program> logger) =>
+    {
+        // additional application logic
+        return Results.Accepted();
+    })
+    .AddEndpointFilter(new AocGuardEndpointFilter<IngestionRequest>(
+        request => new object?[] { request.Payload },
+        serializerOptions: null,
+        guardOptions: null))
+    .ProducesProblem(StatusCodes.Status400BadRequest)
+    .WithTags("AOC");
+
+app.UseExceptionHandler(errorApp =>
+{
+    errorApp.Run(async context =>
+    {
+        var exceptionHandler = context.Features.Get<IExceptionHandlerFeature>();
+        if (exceptionHandler?.Error is AocGuardException guardException)
+        {
+            var result = AocHttpResults.Problem(context, guardException);
+            await result.ExecuteAsync(context);
+            return;
+        }
+
+        context.Response.StatusCode = StatusCodes.Status500InternalServerError;
+    });
+});
+```
+
+Key points:
+- Register the guard singleton before wiring repositories or worker services.
+- Use `AocGuardEndpointFilter<TRequest>` to protect Minimal API endpoints. The `payloadSelector`
+  can yield multiple payloads (e.g. batch ingestion) and the filter will validate each one.
+- Wrap guard exceptions with `AocHttpResults.Problem` to ensure clients receive machine-readables codes (`ERR_AOC_00x`).
+
+## Worker / repository usage
+
+Inject `IAocGuard` (or a module-specific wrapper such as `IVexRawWriteGuard`) anywhere documents
+are persisted. Call `ValidateOrThrow` before writes to guarantee fail-fast behaviour, for example:
+
+```csharp
+public sealed class AdvisoryRawRepository
+{
+    private readonly IAocGuard _guard;
+
+    public AdvisoryRawRepository(IAocGuard guard) => _guard = guard;
+
+    public Task WriteAsync(JsonDocument document, CancellationToken cancellationToken)
+    {
+        _guard.ValidateOrThrow(document.RootElement);
+        // proceed with storage logic
+    }
+}
+```
+
+## Configuration tips
+
+- Adjust `AocGuardOptions.RequiredTopLevelFields` when staging new schema changes. All configured names are case-insensitive.
+- Set `RequireSignatureMetadata = false` for legacy feeds that do not provide signature envelopes yet; track the waiver in the module backlog.
+- Use module-specific wrappers (`AddConcelierAocGuards`, `AddExcititorAocGuards`) to combine guard registration with domain exceptions and metrics.
+
+## Testing guidance
+
+- Unit-test guard behaviour with fixture payloads (see `src/Aoc/__Tests`).
+- Service-level tests should assert that ingestion endpoints return `ERR_AOC_*` codes via `AocHttpResults`.
+- CI must run `stella aoc verify` once CLI support lands (`DEVOPS-AOC-19-002`).
+- Roslyn analyzer enforcement (`WEB-AOC-19-003`) will ensure the guard is registered; keep services wired through the shared extensions to prepare for that gate.
