+
+## Unblocking Plan: Orchestrator SDK Integration
+
+### Blocker Analysis
+
+**Root Cause:** Task 8 (EXCITITOR-ORCH-32/33) is blocked on selecting and confirming the orchestrator SDK version for Excititor worker adoption.
+
+**Blocked Tasks (1 total):**
+- EXCITITOR-ORCH-32/33: Adopt orchestrator worker SDK; honor pause/throttle/retry with deterministic checkpoints
+
+**What's Already Done:**
+- ✅ Storage backend decision: Postgres append-only store selected
+- ✅ Schema freeze: Overlay contract v1.0.0 frozen
+- ✅ Tasks 1-6 and 9-10 completed
+- ✅ Evidence/attestation endpoints re-enabled
+
+### Context
+
+The Excititor worker needs to adopt the platform's orchestrator SDK to support:
+- **Pause/Resume:** Graceful handling of worker pause signals
+- **Throttle:** Rate limiting based on system load
+- **Retry:** Automatic retry with exponential backoff
+- **Checkpointing:** Deterministic progress tracking on Postgres store
+
+### SDK Options
+
+#### Option A: StellaOps.Scheduler.Worker SDK
+**Status:** Exists in codebase
+**Location:** `src/Scheduler/__Libraries/StellaOps.Scheduler.Worker/`
+
+**Features:**
+- Job scheduling with cron expressions
+- State machine for job lifecycle
+- PostgreSQL-backed checkpoints
+- Retry policies
+
+**Integration:**
+```csharp
+// Register in Excititor.Worker DI
+services.AddSchedulerWorker(options =>
+{
+    options.WorkerId = "excititor-worker";
+    options.CheckpointStore = "postgres";
+});
+
+// Implement IScheduledJob
+public class VexIngestionJob : IScheduledJob
+{
+    public string CronExpression => "*/5 * * * *"; // Every 5 minutes
+
+    public async Task ExecuteAsync(CancellationToken cancellationToken)
+    {
+        // Ingest VEX documents
+    }
+}
+```
+
+#### Option B: Generic Orchestrator SDK (New)
+**Status:** Proposed
+**Location:** Would be `src/__Libraries/StellaOps.Orchestrator.Sdk/`
+
+**Features:**
+- Event-driven worker pattern
+- Distributed checkpointing
+- Pause/throttle/retry primitives
+- Tenant-aware work distribution
+
+**Considerations:**
+- Requires new SDK development
+- More flexible than Scheduler.Worker
+- Higher initial investment
+
+#### Option C: Minimal Custom Implementation
+**Status:** Can implement directly
+**Location:** `src/Excititor/StellaOps.Excititor.Worker/`
+
+**Features:**
+- Simple polling loop with checkpoint
+- Manual retry logic
+- Direct Postgres checkpoint storage
+
+**Trade-offs:**
+- Fastest to implement
+- Less reusable
+- May duplicate patterns from other workers
+
+### Unblocking Recommendation
+
+**Recommended: Option A (StellaOps.Scheduler.Worker SDK)**
+
+**Rationale:**
+1. SDK already exists in codebase
+2. PostgreSQL checkpointing is proven
+3. Consistent with other module workers
+4. Retry/backoff policies are implemented
+5. Lower risk than new SDK development
+

+                throw;
+            }
+        }
+    }

+## Unblocking Plan: Category C Migrations
+
+### Blocker Analysis
+
+**Root Cause:** Data migrations for 4 tables (scheduler.audit, vuln.merge_events, vex.timeline_events, notify.deliveries) require production downtime to safely migrate data to partitioned tables and swap table names.
+
+**Blocked Tasks (14 total):**
+- Phase 2 (scheduler.audit): 2.3, 2.4, 2.5, 2.8, 2.9
+- Phase 3 (vuln.merge_events): 3.3, 3.4, 3.5, 3.7
+- Phase 4 (vex.timeline_events): 4.2, 4.3, 4.4
+- Phase 5 (notify.deliveries): 5.2, 5.3, 5.4
+
+**What's Already Done:**
+- ✅ Phase 1: Infrastructure (partition management functions)
+- ✅ Phase 6: Automation & Monitoring (maintenance job, health monitor)
+- ✅ Partitioned tables created for all 4 schemas
+- ✅ BRIN indexes added on temporal columns
+- ✅ Initial monthly partitions created
+
+### Unblocking Options
+
+#### Option A: Scheduled Maintenance Window (Recommended)
+**Effort:** 4-8 hours downtime
+**Risk:** Low (proven approach)
+
+1. **Schedule Window:** Coordinate with ops team for off-peak maintenance window
+   - Recommended: Weekend early morning (02:00-06:00 UTC)
+   - Notify stakeholders 1 week in advance
+   - Prepare rollback scripts
+
+2. **Execute Sequentially:**
+   ```
+   For each table (scheduler.audit → vuln.merge_events → vex.timeline_events → notify.deliveries):
+     1. Disable application writes (feature flag/maintenance mode)
+     2. Run data migration: INSERT INTO {table}_partitioned SELECT * FROM {table}
+     3. Verify row counts match
+     4. Swap table names (ALTER TABLE ... RENAME)
+     5. Update application config/queries if needed
+     6. Validate partition distribution
+     7. Re-enable writes
+   ```
+
+3. **Validation:**
+   - Run partition health checks
+   - Verify BRIN index efficiency
+   - Monitor query performance for 24h
+
+#### Option B: Zero-Downtime Online Migration
+**Effort:** 2-3 days implementation + 1 week migration window
+**Risk:** Medium (more complex)
+
+1. **Implement Dual-Write Trigger:**
+   ```sql
+   CREATE TRIGGER trg_dual_write_{table}
+     AFTER INSERT ON {schema}.{table}
+     FOR EACH ROW EXECUTE FUNCTION {schema}.dual_write_{table}();
+   ```
+
+2. **Backfill Historical Data:**
+   - Run batched INSERT in background (10k rows/batch)
+   - Monitor replication lag
+   - Target: 48-72h for full backfill
+
+3. **Cutover:**
+   - Verify row counts match
+   - Brief write pause (<30s)
+   - Swap table names
+   - Drop dual-write trigger
+
+#### Option C: Incremental Per-Table Migration
+**Effort:** 4 separate windows (1-2h each)
+**Risk:** Low (smaller scope per window)
+
+Migrate one table at a time across 4 separate maintenance windows:
+- Week 1: scheduler.audit (lowest impact)
+- Week 2: notify.deliveries
+- Week 3: vex.timeline_events
+- Week 4: vuln.merge_events (highest volume)

+

+
+## Unblocking Plan: Native Analyzer Persistence Integration
+
+### Blocker Analysis
+
+**Root Cause:** Design decision needed for how Scanner.Worker should persist Unknowns records. Two architectural approaches are available, and the choice affects the dependency graph and testability.
+
+**Blocked Tasks (2 total):**
+- NUC-003B: Wire native analyzer outputs to Unknowns (persistence layer decision)
+- NUC-004: Integrate with native analyzer (blocked by NUC-003B)
+
+**What's Already Done:**
+- ✅ NUC-001: UnknownKind enum values added
+- ✅ NUC-002: NativeUnknownContext model created
+- ✅ NUC-003: NativeUnknownClassifier service implemented
+- ✅ NUC-003A: Scanner.Worker references Unknowns.Core
+- ✅ NUC-005: Unit tests (14 tests passing)
+
+### Design Options
+
+#### Option A: Direct Postgres Reference (Simpler)
+**Pros:** Fewer abstractions, direct persistence, matches existing patterns
+**Cons:** Tighter coupling, harder to test without database
+
+```
+Scanner.Worker → Unknowns.Core
+Scanner.Worker → Unknowns.Storage.Postgres
+```
+
+**Implementation:**
+1. Add project reference: `Scanner.Worker → Unknowns.Storage.Postgres`
+2. Register `IUnknownRepository` from Postgres storage in DI
+3. Call repository directly from analyzer output handler:
+   ```csharp
+   // In native analyzer output handler
+   var unknown = _classifier.Classify(binaryContext);
+   await _unknownRepository.CreateAsync(unknown, ct);
+   ```
+
+#### Option B: Abstraction Layer (Recommended)
+**Pros:** Decoupled, testable, supports different storage backends
+**Cons:** Additional abstraction layer
+
+```
+Scanner.Worker → Unknowns.Core (IUnknownPersister)
+Scanner.WebService → Unknowns.Storage.Postgres (PostgresUnknownPersister)
+```
+
+**Implementation:**
+1. Create `IUnknownPersister` interface in Unknowns.Core:
+   ```csharp
+   public interface IUnknownPersister
+   {
+       Task PersistAsync(Unknown unknown, CancellationToken ct = default);
+       Task PersistBatchAsync(IEnumerable<Unknown> unknowns, CancellationToken ct = default);
+   }
+   ```
+
+2. Implement in Unknowns.Storage.Postgres:
+   ```csharp
+   public class PostgresUnknownPersister : IUnknownPersister
+   {
+       private readonly IUnknownRepository _repository;
+       // ...
+   }
+   ```
+
+3. Scanner.Worker depends only on IUnknownPersister
+4. DI registration in Scanner.WebService wires PostgresUnknownPersister
+
+#### Option C: Event-Based (Decoupled)
+**Pros:** Fully decoupled, async processing, audit trail
+**Cons:** More complex, eventual consistency
+
+```
+Scanner.Worker → publishes UnknownCreatedEvent
+Unknowns.Worker → consumes event → persists to Postgres
+```
+
+**Implementation:**
+1. Scanner.Worker publishes `UnknownCreatedEvent` to message bus
+2. Unknowns module has its own worker that consumes events
+3. Events stored in event store for replay/audit
+
+### Unblocking Tasks
+
+| Task | Description | Owner | Due |
+|------|-------------|-------|-----|
+| UNBLOCK-3500-001 | Review design options with Architecture Guild | Unknowns Guild | TBD |
+| UNBLOCK-3500-002 | Document chosen approach in ADR | Architecture Guild | After review |

+| UNBLOCK-3500-005 | Complete NUC-004 native analyzer integration | Scanner Guild | After 004 |
+
+### Recommended Decision
+
+**Recommendation:** Option B (Abstraction Layer)
+
+**Rationale:**
+1. **Consistency:** Matches existing patterns in codebase (e.g., IVexRepository abstraction)
+2. **Testability:** Scanner.Worker tests can use in-memory persister
+3. **Flexibility:** Allows future storage backends (e.g., CAS, Redis cache)
+4. **Separation:** Keeps Scanner.Worker focused on scanning, not storage details
+
+### Decision Template
+
+```markdown
+## ADR: Unknowns Persistence Integration
+
+**Status:** PROPOSED
+**Date:** TBD
+**Decision:** [A/B/C]
+**Rationale:** [Reasoning]
+**Consequences:** [Impact on codebase]
+**Approved by:** @architecture-guild
+```
+
+### Next Steps
+
+1. Schedule architecture review (15-30 min)
+2. Document decision in ADR
+3. Implement chosen approach
+4. Unblock NUC-003B and NUC-004

+## Unblocking Plan: Integration Tests
+
+### Blocker Analysis
+
+**Root Cause:** REACH-013 (Integration tests with end-to-end flow) requires mock setup for `IReachabilityGraphService` and `ICallGraphAccessor` fixtures which are not yet available.
+
+**Blocked Tasks (1 total):**
+- REACH-013: Integration tests with end-to-end flow
+
+**What's Already Done:**
+- ✅ REACH-001 through REACH-012: All core implementation complete
+- ✅ REACH-014, REACH-015: Documentation and metrics
+- ✅ SurfaceQueryServiceTests: Unit tests passing
+
+### Missing Test Infrastructure
+
+1. **IReachabilityGraphService Mock:**
+   - Needs to return pre-built call graphs
+   - Should support multiple test scenarios (reachable, unreachable, partial)
+
+2. **ICallGraphAccessor Fixture:**
+   - Requires sample call graph data
+   - Should represent realistic application structure
+
+3. **ISurfaceRepository Mock:**
+   - Needs surface/trigger test data
+   - Should support lookup by (CVE, ecosystem, package, version)
+
+### Unblocking Options
+
+#### Option A: In-Memory Test Fixtures (Recommended)
+**Effort:** 1-2 days
+**Risk:** Low
+
+1. **Create Test Call Graph Builder:**
+   ```csharp
+   public class TestCallGraphBuilder
+   {
+       public static CallGraph CreateSimpleWebApi()
+       {
+           // Creates: Entrypoint → Controller → Service → VulnerableLib.Method()
+       }
+
+       public static CallGraph CreateWithMultiplePaths()
+       {
+           // Multiple entrypoints, branching paths to sink
+       }
+
+       public static CallGraph CreateUnreachable()
+       {
+           // Sink exists but no path from entrypoints
+       }
+   }
+   ```
+
+2. **Create Test Surface Data:**
+   ```csharp
+   public class TestSurfaceBuilder
+   {
+       public static VulnSurface CreateForCve(string cveId, params string[] triggerMethods)
+       {
+           return new VulnSurface
+           {
+               CveId = cveId,
+               Ecosystem = "npm",
+               Package = "test-package",
+               Triggers = triggerMethods.Select(m => new TriggerMethod(m)).ToList()
+           };
+       }
+   }
+   ```
+
+3. **Wire Into Integration Tests:**
+   ```csharp
+   public class ReachabilityIntegrationTests
+   {
+       private readonly InMemorySurfaceRepository _surfaceRepo;
+       private readonly InMemoryCallGraphAccessor _graphAccessor;
+       private readonly SurfaceAwareReachabilityAnalyzer _analyzer;
+
+       [Fact]
+       public async Task Confirmed_WhenSurfaceTriggerIsReachable()
+       {
+           // Arrange
+           var graph = TestCallGraphBuilder.CreateSimpleWebApi();
+           var surface = TestSurfaceBuilder.CreateForCve("CVE-2024-1234", "VulnerableLib.Deserialize");
+           _surfaceRepo.Add(surface);
+           _graphAccessor.Set(graph);
+
+           // Act
+           var result = await _analyzer.AnalyzeVulnerabilityAsync(graph, vuln, CancellationToken.None);
+
+           // Assert
+           Assert.Equal(ReachabilityConfidenceTier.Confirmed, result.ConfidenceTier);
+       }
+   }
+   ```
+
+#### Option B: Testcontainers with Real Services
+**Effort:** 3-5 days
+**Risk:** Medium (infrastructure complexity)
+
+Full E2E with containerized services:
+1. PostgreSQL with surface data
+2. Scanner API with call graph endpoints
+3. Test orchestration via Testcontainers
+
+#### Option C: Contract Tests
+**Effort:** 1 day
+**Risk:** Low (but less coverage)
+
+Test service contracts without full E2E:
+1. Verify SurfaceQueryService returns correct format
+2. Verify ReachabilityAnalyzer accepts expected inputs
+3. Verify result format matches API contract

+## Unblocking Plan: CycloneDX 1.7 Support
+
+### Blocker Analysis
+
+**Root Cause:** CycloneDX.Core NuGet package version 10.0.2 does not expose `SpecificationVersion.v1_7` enum value. The CycloneDX 1.7 specification was released October 2025, but the .NET library has not yet been updated to support it.
+
+**Blocked Tasks (5 total):**
+- 1.1 Research CycloneDX.Core 10.0.2+ (library doesn't support v1_7)
+- 1.3 Update Specification Version (cannot set `SpecificationVersion.v1_7`)
+- 1.4 Update Media Type Constants (should follow code upgrade)
+- 1.5 Update Documentation (docs should reflect actual code)
+- 1.7 Validate Acceptance Criteria (cannot validate without implementation)
+
+**What's Already Done:**
+- ✅ Updated CycloneDX.Core to 10.0.2
+- ✅ All tests pass with CycloneDX 1.6
+- ✅ Signal mapping documentation complete (Task 2)
+- ✅ EPSS clarification documentation complete (Task 3)
+- ✅ Alignment report complete (Task 4)
+
+### Unblocking Options
+
+#### Option A: Wait for Upstream Library (Recommended if timeline allows)
+**Effort:** 0 (monitoring only)
+**Risk:** Unknown timeline
+
+1. **Monitor CycloneDX.Core Releases:**
+   - GitHub: https://github.com/CycloneDX/cyclonedx-dotnet-library/releases
+   - NuGet: https://www.nuget.org/packages/CycloneDX.Core
+   - Subscribe to release notifications
+
+2. **Track Issue:**
+   - Search/create issue for v1_7 support on GitHub
+   - Engage with maintainers if urgent
+
+3. **When Available:**
+   - Update package reference
+   - Change `SpecificationVersion.v1_6` → `SpecificationVersion.v1_7`
+   - Update media type strings
+   - Run tests and validate
+
+#### Option B: Fork and Patch (For urgent timeline)
+**Effort:** 1-2 days
+**Risk:** Maintenance overhead
+
+1. **Fork Repository:**
+   ```bash
+   git clone https://github.com/CycloneDX/cyclonedx-dotnet-library
+   ```
+
+2. **Add v1_7 Enum Value:**
+   - File: `CycloneDX.Core/Enums/SpecificationVersion.cs`
+   - Add: `v1_7 = 7`
+
+3. **Update Serialization:**
+   - Add v1_7 handling in JSON/XML serializers
+   - Map to spec version string "1.7"
+
+4. **Build and Publish:**
+   - Build forked package
+   - Publish to private NuGet feed (configured in `nuget.config`)
+   - Reference: `<PackageReference Include="CycloneDX.Core" Version="10.0.3-stellaops" />`
+
+5. **Track Upstream:**
+   - Submit PR to upstream with v1_7 support
+   - Plan migration back to official package when released
+
+#### Option C: String-Based Workaround (Minimal changes)
+**Effort:** 0.5 days
+**Risk:** Bypasses type safety
+
+1. **Create Extension:**
+   ```csharp
+   // File: src/Scanner/__Libraries/StellaOps.Scanner.Emit/Extensions/CycloneDxExtensions.cs
+
+   public static class CycloneDxExtensions
+   {
+       /// <summary>
+       /// Workaround for CycloneDX.Core not yet supporting v1_7.
+       /// Sets spec version string directly in serialized output.
+       /// </summary>
+       public static void SetSpecVersion17(this Bom bom)
+       {
+           // For JSON serialization, post-process to replace "specVersion": "1.6"
+           // with "specVersion": "1.7"
+       }
+   }
+   ```
+
+2. **Post-Process Serialization:**
+   - Serialize with v1_6
+   - Replace version string in output: `"specVersion": "1.6"` → `"specVersion": "1.7"`
+   - Update media type headers separately
+
+3. **Limitations:**
+   - Doesn't validate 1.7-specific fields
+   - Requires migration when official support arrives
+
+#### Option D: Defer to CycloneDX 1.6 (Pragmatic)
+**Effort:** 0
+**Risk:** None (already working)
+
+1. **Document Decision:**
+   - CycloneDX 1.6 is current StellaOps baseline
+   - 1.7 upgrade planned for when library supports it
+   - No breaking changes expected between 1.6 and 1.7
+
+2. **Update Sprint Status:**
+   - Mark tasks 1.3-1.7 as DEFERRED (not BLOCKED)
+   - Create tracking issue for future upgrade
+   - Set milestone for Q1 2026
+
+3. **Alignment Impact:**
+   - Current alignment: 95%
+   - v1_7 is minor enhancement, not blocking requirement
+   - All critical features already compliant
+
+### Unblocking Tasks
+
+| Task | Description | Owner | Due |
+|------|-------------|-------|-----|
+| UNBLOCK-5000-001 | Create GitHub issue to track CycloneDX.Core v1_7 support | Scanner Guild | Immediate |
+| UNBLOCK-5000-002 | Subscribe to CycloneDX.Core release notifications | Scanner Guild | Immediate |
+| UNBLOCK-5000-003 | Decide on approach (A, B, C, or D) based on timeline | Tech Lead | TBD |
+| UNBLOCK-5000-004 | If Option B: Fork and add v1_7 enum | Scanner Guild | If urgent |
+| UNBLOCK-5000-005 | Update sprint when library available | Scanner Guild | When released |
+
+### Recommended Action
+
+**If timeline is flexible:** Option D (defer) - document 1.6 as current baseline, upgrade when library supports 1.7.
+
+**If timeline is urgent:** Option B (fork) - fork library, add v1_7, use private feed, submit PR upstream.

+## Unblocking Plan: UI Integration
+
+### Blocker Analysis
+
+**Root Cause:** Two tasks remain blocked due to missing infrastructure:
+
+1. **UI-011 (PR View Component):** The RiskDriftCard cannot be integrated into PR view because the PR view component does not exist in the Angular application.
+
+2. **UI-025 (CLI Integration Tests):** End-to-end tests require a running Scanner/API instance which is not available in CI.
+
+**Blocked Tasks (2 total):**
+- UI-011: Integrate RiskDriftCard into PR view (component missing)
+- UI-025: Integration tests for CLI (E2E infrastructure missing)
+
+**What's Already Done:**
+- ✅ UI-001 through UI-010: PathViewer, RiskDriftCard, API service, scan detail integration
+- ✅ UI-012 through UI-024: Unit tests, DSSE attestation, CLI commands, SARIF output
+- ✅ All core functionality implemented and tested
+
+### Unblocking Options
+
+#### UI-011: PR View Component
+
+##### Option A: Create PR View Component (New Feature)
+**Effort:** 3-5 days
+**Recommendation:** Defer to separate sprint
+
+The PR view functionality requires:
+1. GitHub/GitLab webhook integration
+2. PR metadata storage
+3. PR-to-scan association
+4. PR summary component
+5. Comment posting API
+
+This is a substantial feature that should be its own sprint (suggested: SPRINT_3600_0005_0001_pr_integration).
+
+##### Option B: Add to Existing Scan Detail (Quick Win)
+**Effort:** 0.5 days
+**Recommendation:** Already done (UI-010)
+
+RiskDriftCard is already integrated into scan-detail-page. PR-specific display can be added later when PR view exists.
+
+##### Option C: Mark as DEFERRED
+**Effort:** 0
+**Recommendation:** Mark task as DEFERRED, not BLOCKED
+
+Since the PR view component is a separate feature, this task should be marked DEFERRED until the PR view sprint is created and completed.
+
+#### UI-025: CLI Integration Tests
+
+##### Option A: Testcontainers-Based E2E
+**Effort:** 2-3 days
+**Recommendation:** Preferred approach
+
+1. Use Testcontainers to spin up Scanner API in test:
+   ```csharp
+   public class DriftCliIntegrationTests : IAsyncLifetime
+   {
+       private PostgreSqlContainer _postgres;
+       private IContainer _scannerApi;
+
+       public async Task InitializeAsync()
+       {
+           _postgres = new PostgreSqlBuilder().Build();
+           await _postgres.StartAsync();
+
+           _scannerApi = new ContainerBuilder()
+               .WithImage("stellaops/scanner:latest")
+               .WithEnvironment("ConnectionStrings__Postgres", _postgres.GetConnectionString())
+               .WithPortBinding(8080, true)
+               .Build();
+           await _scannerApi.StartAsync();
+       }
+   }
+   ```
+
+2. Run CLI against containerized API
+3. Verify output formats (table, JSON, SARIF)
+
+##### Option B: Mock HTTP Client
+**Effort:** 1 day
+**Recommendation:** Already have unit tests
+
+Mock the HTTP client in CLI tests to simulate API responses. This is what UI-019 through UI-024 already do.
+
+##### Option C: Manual E2E Test Suite
+**Effort:** 0.5 days
+**Recommendation:** Document manual test procedure
+
+Create `docs/testing/drift-cli-e2e-tests.md` with manual test procedures:
+1. Prerequisites (running API, test data)
+2. Test scenarios
+3. Expected outputs
+4. Verification checklist
+
+### Unblocking Tasks
+
+| Task | Description | Owner | Due |
+|------|-------------|-------|-----|
+| UNBLOCK-3600-001 | Update UI-011 status to DEFERRED (awaiting PR view sprint) | UI Guild | Immediate |
+| UNBLOCK-3600-002 | Create tracking issue for PR view sprint | Project Mgmt | This sprint |
+| UNBLOCK-3600-003 | Implement Testcontainers E2E for UI-025 | CLI Guild | Optional |
+| UNBLOCK-3600-004 | Document manual E2E test procedure | QA Guild | Alternative |
+| UNBLOCK-3600-005 | Mark UI-025 as DEFERRED if Testcontainers not feasible | Project Mgmt | If needed |
+
+### Recommended Actions
+
+1. **UI-011:** Change status from BLOCKED to DEFERRED. Create SPRINT_3600_0005 for PR integration as a separate feature.
+
+2. **UI-025:** Either implement Testcontainers E2E tests OR mark as DEFERRED with documented manual test procedure.
+
+### Status Update
+
+| Task | Current | Recommended | Reason |
+|------|---------|-------------|--------|
+| UI-011 | BLOCKED | DEFERRED | PR view is separate feature |
+| UI-025 | BLOCKED | DEFERRED or DONE | Manual tests acceptable |
