BuildPhases creates ordered phases: DataFetch→Transform (conditional on redaction/normalization/sorting)→WriteOutput→GenerateManifest→Sign (conditional on Mirror format). `IExportProfileRepository` interface with GetByIdAsync, GetActiveProfilesAsync, CreateAsync, UpdateAsync. `InMemoryExportProfileRepository` implementation with ConcurrentDictionary keyed by (TenantId, ProfileId). Changed ExportProfile from class to record to support `with` expressions in plan updates. Created tests: `ExportScopeResolverTests.cs` (21 test cases for scope resolution, validation, deterministic sampling, estimation), `ExportPlannerTests.cs` (12 test cases for plan creation, validation, cancellation, phase generation, correlation tracking). Core project builds successfully with 0 errors. | Implementer |
+| 2025-12-07 | **EXPORT-SVC-35-001 DONE:** Bootstrapped exporter service with Postgres migrations for export data layer. Created `Configuration/ExportCenterOptions.cs` in Core with: `ExportCenterOptions` (DatabaseOptions, ObjectStoreOptions, TimelineOptions, SigningOptions, QuotaOptions), `DatabaseOptions` (ConnectionString, ApplyMigrationsAtStartup). Created domain models in `Domain/`: `ExportProfile.cs` (ProfileId, TenantId, Name, Description, Kind, Status, ScopeJson, FormatJson, SigningJson, Schedule, timestamps; enums ExportProfileKind AdHoc/Scheduled/EventDriven/Continuous, ExportProfileStatus Draft/Active/Paused/Archived), `ExportRun.cs` (RunId, ProfileId, TenantId, Status, Trigger, CorrelationId, InitiatedBy, item counts, TotalSizeBytes, ErrorJson; enums ExportRunStatus Queued→Cancelled, ExportRunTrigger Manual/Scheduled/Event/Api), `ExportInput.cs` (InputId, RunId, TenantId, Kind, Status, SourceRef, Name, ContentHash, SizeBytes, MetadataJson; enums ExportInputKind Sbom/Vex/Attestation/ScanReport/PolicyResult/Evidence/RiskBundle/Advisory, ExportInputStatus Pending→Skipped), `ExportDistribution.cs` (DistributionId, RunId, TenantId, Kind, Status, Target, ArtifactPath, ArtifactHash, SizeBytes, ContentType, MetadataJson, AttemptCount; enums ExportDistributionKind FileSystem/AmazonS3/Mirror/OfflineKit/Webhook, ExportDistributionStatus Pending→Cancelled). Created database infrastructure in Infrastructure `Db/`: `MigrationScript.cs` (version parsing, SHA256 checksum, line-ending normalization), `MigrationLoader.cs` (loads embedded SQL resources ordered by version), `ExportCenterDataSource.cs` (NpgsqlDataSource with tenant session config via `app.current_tenant`), `ExportCenterMigrationRunner.cs` (applies migrations with checksum validation), `ExportCenterDbServiceExtensions.cs` (DI registration, `ExportCenterMigrationHostedService` for startup migrations). Created `Db/Migrations/001_initial_schema.sql` with schemas export_center/export_center_app, `require_current_tenant()` function, tables (export_profiles, export_runs, export_inputs, export_distributions) with RLS policies, indexes (tenant_status, profile_created, correlation), FK constraints, `update_updated_at` trigger. Updated csproj to add Npgsql 8.0.3 and EmbeddedResource for SQL files. Added tests: `MigrationScriptTests.cs` (version parsing, SHA256 determinism, line-ending normalization), `MigrationLoaderTests.cs` (resource loading, ordering, validation), `ExportProfileTests.cs`/`ExportRunTests.cs`/`ExportInputTests.cs`/`ExportDistributionTests.cs` (domain model construction, enum value verification). Core and Infrastructure projects build successfully with 0 errors. | Implementer |
+| 2025-12-07 | **EXPORT-RISK-70-001 DONE:** Integrated risk bundle builds into offline kit packaging with checksum verification. Added to `OfflineKitModels.cs`: `OfflineKitRiskBundleEntry` record (kind, exportId, bundleId, inputsHash, providers[], rootHash, artifact, checksum, createdAt), `OfflineKitRiskProviderInfo` record (providerId, source, snapshotDate, optional), `OfflineKitRiskBundleRequest` record. Added to `OfflineKitPackager.cs`: `RiskBundlesDir` constant ("risk-bundles"), `RiskBundleFileName` constant ("export-risk-bundle-v1.tgz"), `AddRiskBundle` method (writes bundle to risk-bundles/ directory with SHA256 checksum), `CreateRiskBundleEntry` method (creates manifest entry with provider info). Updated `OfflineKitDistributor.cs`: Added risk bundle detection in `DistributeToMirror` method (checks for risk-bundles/export-risk-bundle-v1.tgz, computes hash, adds entry with CLI example "stella risk-bundle verify/import"). Added tests in `OfflineKitPackagerTests.cs`: `AddRiskBundle_CreatesArtifactAndChecksum`, `AddRiskBundle_PreservesBytesExactly`, `AddRiskBundle_RejectsOverwrite`, `CreateRiskBundleEntry_HasCorrectKind`, `CreateRiskBundleEntry_HasCorrectPaths`, `CreateRiskBundleEntry_IncludesProviderInfo`. Updated `DirectoryStructure_FollowsOfflineKitLayout` test to include risk-bundles directory. Core library builds successfully with 0 errors. | Implementer |
