@@ -612,6 +612,23 @@ SQLite auth storage should use startup migrations with a `schema_version` table.
 Migrations should run inside transactions and fail startup if the database
 schema is newer than the running binary understands.
 
+The v1 auth store uses `Microsoft.Data.Sqlite` and creates the
+`schema_version`, `api_keys`, and `api_key_audit` tables through
+`SqliteAuthStoreMigrator`. `AuthStoreMigrationHostedService` runs those
+migrations at gateway startup when API-key authentication and
+`Authentication:RunMigrationsOnStartup` are enabled. A database with a newer
+schema version fails startup instead of being modified by an older gateway
+binary.
+
+`IApiKeyStore` reads stored key records and exposes an active-key lookup that
+excludes rows with `revoked_utc` set. Hash verification belongs to the API-key
+hashing layer, but the store preserves the `secret_hash` bytes, display name,
+scopes, timestamps, and revocation state needed by that layer.
+
+`IApiKeyAuditStore` appends audit events to `api_key_audit` and returns recent
+events for diagnostics and future administrative tools. Audit records store key
+ids and event metadata only; they do not store raw API key secrets.

+## Build And Test
+
+Build the SDK-style worker project with the .NET SDK MSBuild entry point. The
+project targets .NET Framework 4.8, but the SDK resolver comes from the .NET SDK
+installation:
+
+```powershell
+dotnet msbuild src\MxGateway.Worker\MxGateway.Worker.csproj /restore /p:Configuration=Debug /p:Platform=x86
+```
+
+`docs/toolchain-links.md` records the Visual Studio MSBuild executable for
+classic .NET Framework and COM interop builds:
+
+```powershell
+& "C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\MSBuild\Current\Bin\MSBuild.exe" src\MxGateway.Worker\MxGateway.Worker.csproj /p:Configuration=Debug /p:Platform=x86
+```
+
+Run the worker tests with the same platform target:
+
+```powershell
+dotnet test src\MxGateway.Worker.Tests\MxGateway.Worker.Tests.csproj -p:Platform=x86
+```
+
+The only MXAccess interop reference belongs in `MxGateway.Worker`. Gateway and
+test projects may reference the worker project for metadata and scaffold tests,
+but they must not reference `ArchestrA.MXAccess.dll` directly.
