+# Claude Code Team Strategy for Feature Verification
+
+Alternative to the OpenCode pipeline. Uses Claude Code's built-in team orchestration
+(TeamCreate, Task tools, SendMessage) for parallel feature verification.
+
+---
+
+## Architecture
+
+```
+Team Lead (Opus 4.6)
+  ├── tier0-scanner (Haiku 4.5)     # Fast: source file existence checks
+  ├── checker-1 (Opus 4.6)          # Full pipeline per feature
+  ├── checker-2 (Opus 4.6)          # Parallel checker
+  ├── checker-3 (Opus 4.6)          # Parallel checker
+  ├── triage-agent (Sonnet 4.5)     # Issue diagnosis
+  └── fixer-agent (Opus 4.6)        # Code fixes
+```
+
+## How It Differs from OpenCode
+
+| Aspect | OpenCode | Claude Code Teams |
+|--------|----------|-------------------|
+| State management | JSON state files on disk | TaskCreate/TaskList/TaskUpdate in-memory |
+| Parallelism | Sequential (one feature at a time) | Parallel (multiple agents simultaneously) |
+| Orchestration | Prompt-driven subagent calls | Native team messaging (SendMessage) |
+| File access | All agents share filesystem | All agents share filesystem |
+| Cost model | Per-token across models | Per-token, Opus 4.6 primarily |
+| Session limits | Unlimited (persistent state) | Context window limits (use /compact) |
+| Best for | Long-running unattended pipelines | Interactive sessions with parallelism |
+
+## Execution Plan
+
+### Phase 1: Setup (Team Lead)
+
+```
+1. TeamCreate: "feature-verify-<module>"
+2. TaskCreate: One task per feature in the module
+3. Spawn tier0-scanner agent
+4. Wait for Tier 0 results
+5. Filter: remove not_implemented features
+```
+
+### Phase 2: Parallel Checking (3 Checker Agents)
+
+```
+1. Spawn 3 checker agents
+2. Each checker claims tasks from TaskList (lowest ID first)
+3. For each feature:
+   a. Read feature .md file
+   b. Run Tier 1: dotnet build + dotnet test
+   c. Run Tier 2: Playwright/CLI/API (if applicable)
+   d. TaskUpdate: status=completed or note failures
+   e. Claim next task
+4. Checkers go idle when no tasks remain
+```
+
+### Phase 3: Triage + Fix (if failures found)
+
+```
+1. Team lead reviews completed tasks for failures
+2. For each failure:
+   a. TaskCreate: triage task with failure details
+   b. Send to triage-agent
+   c. triage-agent reads source, returns diagnosis
+   d. Team lead reviews diagnosis
+   e. TaskCreate: fix task with confirmed diagnosis
+   f. Send to fixer-agent
+   g. fixer-agent implements fix
+   h. Team lead re-checks via checker agent
+```
+
+### Phase 4: Cleanup
+
+```
+1. Move passed features: unchecked/ -> checked/
+2. Move not_implemented: unchecked/ -> unimplemented/
+3. Update state summary
+4. Shutdown all agents
+5. TeamDelete
+```
+
+## Claude Code Prompt (Copy-Paste Ready)
+
+Use this prompt to start the team in Claude Code:
+
+```
+You are verifying features for the <MODULE> module of Stella Ops.
+
+Read docs/qa/feature-checks/FLOW.md for the full state machine and tier system.
+
+Your workflow:
+1. Create team "verify-<module>"
+2. Create one task per feature file in docs/features/unchecked/<module>/
+3. Spawn a tier0-scanner (haiku) to verify source files exist for all features
+4. After Tier 0, spawn 3 checker agents (opus) in parallel to run Tier 1 (build+test)
+5. For features that fail, spawn a triage agent (sonnet) to diagnose
+6. For confirmed issues, spawn a fixer agent (opus) to implement fixes
+7. Re-check fixed features
+8. Move passed features to docs/features/checked/<module>/
+9. Report final status and shutdown team
+
+For each feature, write run artifacts to docs/qa/feature-checks/runs/<module>/<feature>/
+
+State file: docs/qa/feature-checks/state/<module>.json
+
+IMPORTANT:
+- Feature files are at docs/features/unchecked/<module>/*.md
+- Each has Implementation Details with source file paths
+- Each has an E2E Test Plan with verification steps
+- Source code is under src/
+- .NET 10 backend, Angular 21 frontend
+- Use dotnet build/test for backend, ng build/test for frontend
+```
+
+## Recommended Test Modules (Side-by-Side Comparison)
+
+For testing both pipelines simultaneously on different modules:
+
+### OpenCode Pipeline: `gateway` (8 features)
+- Pure backend, no Playwright needed
+- Small enough to complete in one session
+- Has rate limiting + circuit breaker logic (meaningful checks)
+- Features: router-back-pressure-middleware, stellarouter-performance-testing-pipeline, + 6 existing
+
+### Claude Code Teams: `graph` (7 features)
+- Pure backend, no Playwright needed
+- Similar size to gateway
+- Has graph data structures (meaningful checks)
+- Features: graph-edge-metadata-with-reason-evidence-provenance, + 6 existing
+
+Both modules are:
+- Small (7-8 features each) - completable in one session
+- Backend-only - no Playwright/environment complexity
+- Meaningful - real logic to verify, not just config
+- Independent - no cross-module dependencies
+
+### Alternative Pair (if you want frontend testing):
+
+- **OpenCode**: `exportcenter` (7 features) - has CLI+UI surface
+- **Claude Code**: `vexlens` (7 features) - has truth-table tests + UI
+
+---
+
+## State File Compatibility
+
+Both strategies use the SAME state file format (`docs/qa/feature-checks/state/<module>.json`)
+and artifact format (`docs/qa/feature-checks/runs/<module>/<feature>/<runId>/`).
+
+This means you can:
+- Start with OpenCode on module A
+- Start with Claude Code on module B
+- Compare results using the same state format
+- Switch strategies mid-stream if one works better

+# Feature Verification Pipeline - FLOW
+
+This document defines the state machine, tier system, artifact format, and priority rules
+for the automated feature verification pipeline.
+
+All agents in the pipeline MUST read this document before taking any action.
+
+---
+
+## 1. Directory Layout
+
+```
+docs/features/
+  unchecked/<module>/<feature>.md    # Input: features to verify (1,144 files)
+  checked/<module>/<feature>.md      # Output: features that passed verification

+  runs/<module>/<feature>/<runId>/   # Artifacts per verification run
+```
+

+
+## 2. State Machine
+
+### 2.1 States
+
+| State | Meaning |
+|-------|---------|
+| `queued` | Discovered, not yet processed |
+| `checking` | Feature checker is running |
+| `passed` | All tier checks passed |
+| `failed` | Check found issues (pre-triage) |
+| `triaged` | Issue-finder identified root cause |
+| `confirmed` | Issue-confirmer validated triage |
+| `fixing` | Fixer is implementing the fix |
+| `retesting` | Retester is re-running checks |
+| `done` | Verified and moved to `checked/` |
+| `blocked` | Requires human intervention |
+| `skipped` | Cannot be automatically verified (manual-only) |
+| `not_implemented` | Source files missing despite sprint claiming DONE |
+
+### 2.2 Transitions
+
+```

+               │
+               v
+         [move file to checked/]
+```
+
+### 2.3 Retry Policy
+
+- Maximum retry count: **3** per feature
+- After 3 retries with failures: transition to `blocked`
+- Blocked features require human review before re-entering the pipeline
+- Each retry increments `retryCount` in state
+
+### 2.4 Skip Criteria
+
+Features that CANNOT be automatically E2E tested should be marked `skipped`:
+- Air-gap/offline features (require disconnected environment)
+- Crypto-sovereign features (require HSM/eIDAS hardware)
+- Multi-node cluster features (require multi-host setup)
+- Performance benchmarking features (require dedicated infra)
+- Features with description containing "manual verification required"
+
+The checker agent determines skip eligibility during Tier 0.
+
+---
+
+## 3. Tier System
+
+Verification proceeds in tiers. Each tier is a gate - a feature must pass
+the current tier before advancing to the next. **A feature is NOT verified
+until ALL applicable tiers pass.** File existence alone is not verification.
+
+### Tier 0: Source Verification (fast, cheap)
+
+**Purpose**: Verify that the source files referenced in the feature file actually exist.
+
+**Process**:
+1. Read the feature `.md` file
+2. Extract file paths from `## Implementation Details`, `## Key files`, or `## What's Implemented` sections
+3. For each path, check if the file exists on disk
+4. Extract class/interface names and grep for their declarations
+
+**Outcomes**:
+- All key files found: `source_verified = true`, advance to Tier 1
+- Key files missing (>50% absent): `status = not_implemented`
+- Some files missing (<50% absent): `source_verified = partial`, add note, advance to Tier 1
+
+**What this proves**: The code exists on disk. Nothing more.
+
+**Cost**: ~0.01 USD per feature (file existence checks only)
+
+### Tier 1: Build + Code Review (medium)
+
+**Purpose**: Verify the module compiles, tests pass, AND the code actually implements
+the described behavior.
+
+**Process**:
+1. Identify the `.csproj` file(s) for the feature's module
+2. Run `dotnet build <project>.csproj` and capture output
+3. Run `dotnet test <test-project>.csproj --filter <relevant-filter>` -- tests MUST actually execute and pass
+4. For Angular/frontend features: run `npx ng build` and `npx ng test` for the relevant library/app
+5. **Code review** (CRITICAL): Read the key source files and verify:
+   - The classes/methods described in the feature file actually contain the logic claimed
+   - The feature description matches what the code does (not just that it exists)
+   - Tests cover the core behavior described in the feature (not just compilation)
+6. If the build succeeds but tests are blocked by upstream dependency errors:
+   - Record as `build_verified = true, tests_blocked_upstream = true`
+   - The feature CANNOT advance to `passed` -- mark as `failed` with category `env_issue`
+   - The upstream blocker must be resolved before the feature can pass
+
+**Code Review Checklist** (must answer YES to all):
+- [ ] Does the main class/service exist with non-trivial implementation (not stubs/TODOs)?
+- [ ] Does the logic match what the feature description claims?
+- [ ] Are there unit tests that exercise the core behavior?
+- [ ] Do those tests actually assert meaningful outcomes (not just "doesn't throw")?
+
+**Outcomes**:
+- Build + tests pass + code review confirms behavior: `build_verified = true`, advance to Tier 2
+- Build fails: `status = failed`, record build errors
+- Tests fail or blocked: `status = failed`, record reason
+- Code review finds stubs/missing logic: `status = failed`, category = `missing_code`
+
+**What this proves**: The code compiles, tests pass, and someone has verified the code
+does what it claims.
+
+**Cost**: ~0.10 USD per feature (compile + test execution + code reading)
+
+### Tier 2: Behavioral Verification (API / CLI / UI)
+
+**Purpose**: Verify the feature works end-to-end by actually exercising it through
+its external interface. This is the only tier that proves the feature WORKS, not
+just that code exists.
+
+**EVERY feature MUST have a Tier 2 check unless explicitly skipped.** The check type
+depends on the module's external surface.
+
+#### Tier 2a: API Testing (Gateway, Router, Api, Platform, backend services with HTTP endpoints)
+
+**Process**:
+1. Ensure the service is running (check port, or start via `docker compose up`)
+2. Send HTTP requests to the feature's endpoints using `curl` or a test script
+3. Verify response status codes, headers, and body structure
+4. Test error cases (unauthorized, bad input, rate limited, etc.)
+5. Verify the behavior described in the feature file actually happens
+
+**Example for `gateway-identity-header-strip`**:
+```bash
+# Send request with spoofed identity header
+curl -H "X-Forwarded-User: attacker" http://localhost:5000/api/test
+# Verify the header was stripped (response should use authenticated identity, not spoofed)
+```
+
+**Artifact**: `tier2-api-check.json`
+```json
+{
+  "type": "api",
+  "baseUrl": "http://localhost:5000",
+  "requests": [
+    {
+      "description": "Verify spoofed identity header is stripped",
+      "method": "GET",
+      "path": "/api/test",
+      "headers": { "X-Forwarded-User": "attacker" },
+      "expectedStatus": 200,
+      "actualStatus": 200,
+      "assertion": "Response X-Forwarded-User header matches authenticated user, not 'attacker'",
+      "result": "pass|fail",
+      "evidence": "actual response headers/body"
+    }
+  ],
+  "verdict": "pass|fail|skip"
+}
+```
+
+#### Tier 2b: CLI Testing (Cli, Tools, Bench modules)
+
+**Process**:
+1. Build the CLI tool if needed
+2. Run the CLI command described in the feature's E2E Test Plan
+3. Verify stdout/stderr output matches expected behavior
+4. Test error cases (invalid args, missing config, etc.)
+5. Verify exit codes
+
+**Example for `cli-baseline-selection-logic`**:
+```bash
+stella scan --baseline last-green myimage:latest
+# Verify output shows baseline was selected correctly
+echo $?  # Verify exit code 0
+```
+
+**Artifact**: `tier2-cli-check.json`
+```json
+{
+  "type": "cli",
+  "commands": [
+    {
+      "description": "Verify baseline selection with last-green strategy",
+      "command": "stella scan --baseline last-green myimage:latest",
+      "expectedExitCode": 0,
+      "actualExitCode": 0,
+      "expectedOutput": "Using baseline: ...",
+      "actualOutput": "...",
+      "result": "pass|fail"
+    }
+  ],
+  "verdict": "pass|fail|skip"
+}
+```
+
+#### Tier 2c: UI Testing (Web, ExportCenter, DevPortal, VulnExplorer, PacksRegistry)
+
+**Process**:
+1. Ensure the Angular app is running (`ng serve` or docker)
+2. Use Playwright CLI or MCP to navigate to the feature's UI route
+3. Follow E2E Test Plan steps: verify elements render, interactions work, data displays
+4. Capture screenshots as evidence
+5. Test accessibility (keyboard navigation, ARIA labels) if listed in E2E plan
+
+**Example for `pipeline-run-centric-view`**:
+```bash
+npx playwright test --grep "pipeline-run" --reporter=json
+# Or manually via MCP: navigate to /release-orchestrator/runs, verify table renders
+```
+
+**Artifact**: `tier2-ui-check.json`
+```json
+{
+  "type": "ui",
+  "baseUrl": "http://localhost:4200",
+  "steps": [
+    {
+      "description": "Navigate to /release-orchestrator/runs",
+      "action": "navigate",
+      "target": "/release-orchestrator/runs",
+      "expected": "Runs list table renders with columns",
+      "result": "pass|fail",
+      "screenshot": "step-1-runs-list.png"
+    }
+  ],
+  "verdict": "pass|fail|skip"
+}
+```
+
+#### Tier 2d: Library/Internal Testing (Attestor, Policy, Scanner, etc. with no external surface)
+
+For modules with no HTTP/CLI/UI surface, Tier 2 means running **targeted
+integration tests** or **behavioral unit tests** that prove the feature logic:
+
+**Process**:
+1. Identify tests that specifically exercise the feature's behavior
+2. Run those tests: `dotnet test --filter "FullyQualifiedName~FeatureClassName"`
+3. Read the test code to confirm it asserts meaningful behavior (not just "compiles")
+4. If no behavioral tests exist, write a focused test and run it
+
+**Example for `evidence-weighted-score-model`**:
+```bash
+dotnet test --filter "FullyQualifiedName~EwsCalculatorTests"
+# Verify: normalizers produce expected dimension scores
+# Verify: guardrails cap/floor scores correctly
+# Verify: composite score is deterministic for same inputs
+```
+
+**Artifact**: `tier2-integration-check.json`
+```json
+{
+  "type": "integration",
+  "testFilter": "FullyQualifiedName~EwsCalculatorTests",
+  "testsRun": 21,
+  "testsPassed": 21,
+  "testsFailed": 0,
+  "behaviorVerified": [
+    "6-dimension normalization produces expected scores",
+    "Guardrails enforce caps and floors",
+    "Composite score is deterministic"
+  ],
+  "verdict": "pass|fail"
+}
+```
+
+### When to skip Tier 2
+
+Mark `skipped` ONLY for features that literally cannot be tested in the current environment:
+- Air-gap features requiring a disconnected network
+- HSM/eIDAS features requiring physical hardware
+- Multi-datacenter features requiring distributed infrastructure
+- Performance benchmark features requiring dedicated load-gen infrastructure
+
+"The app isn't running" is NOT a skip reason -- it's a `failed` with `env_issue`.
+"No tests exist" is NOT a skip reason -- write a focused test.
+
+### Tier Classification by Module
+
+| Tier 2 Type | Modules | Feature Count |
+|-------------|---------|---------------|
+| 2a (API) | Gateway, Router, Api, Platform | ~30 |
+| 2b (CLI) | Cli, Tools, Bench | ~110 |
+| 2c (UI/Playwright) | Web, ExportCenter, DevPortal, VulnExplorer, PacksRegistry | ~190 |
+| 2d (Integration) | Attestor, Policy, Scanner, BinaryIndex, Concelier, Libraries, EvidenceLocker, Orchestrator, Signals, Authority, Signer, Cryptography, ReachGraph, Graph, RiskEngine, Replay, Unknowns, Scheduler, TaskRunner, Timeline, Notifier, Findings, SbomService, Mirror, Feedser, Analyzers | ~700 |
+| Manual (skip) | AirGap (subset), SmRemote (HSM), DevOps (infra) | ~25 |
+
+---
+
+## 4. State File Format
+
+Per-module state files live at `docs/qa/feature-checks/state/<module>.json`.
+
+```json
+{
+  "module": "gateway",
+  "featureCount": 8,
+  "lastUpdatedUtc": "2026-02-09T12:00:00Z",
+  "features": {
+    "router-back-pressure-middleware": {
+      "status": "queued",
+      "tier": 0,
+      "retryCount": 0,
+      "sourceVerified": null,
+      "buildVerified": null,
+      "e2eVerified": null,
+      "skipReason": null,
+      "lastRunId": null,
+      "lastUpdatedUtc": "2026-02-09T12:00:00Z",
+      "featureFile": "docs/features/unchecked/gateway/router-back-pressure-middleware.md",
+      "notes": []
+    }
+  }
+}
+```
+
+### State File Rules
+
+- **Single writer**: Only the orchestrator writes state files
+- **Subagents report back**: Subagents return results to the orchestrator via their output; they do NOT write state files directly
+- **Atomic updates**: Each state transition must update `lastUpdatedUtc`
+- **Append-only notes**: The `notes` array is append-only; never remove entries
+
+---
+
+## 5. Run Artifact Format
+
+Each verification run produces artifacts under:
+`docs/qa/feature-checks/runs/<module>/<feature-slug>/<runId>/`
+
+Where `<runId>` = `run-001`, `run-002`, etc. (zero-padded, sequential).
+
+### Required Artifacts
+
+| Stage | File | Format |
+|-------|------|--------|
+| Tier 0 | `tier0-source-check.json` | `{ "filesChecked": [...], "found": [...], "missing": [...], "verdict": "pass\|fail\|partial" }` |
+| Tier 1 | `tier1-build-check.json` | `{ "project": "...", "buildResult": "pass\|fail", "testResult": "pass\|fail\|skipped", "errors": [...] }` |
+| Tier 2 | `tier2-e2e-check.json` | `{ "steps": [{ "description": "...", "result": "pass\|fail", "evidence": "..." }], "screenshots": [...] }` |
+| Triage | `triage.json` | `{ "rootCause": "...", "category": "missing_code\|bug\|config\|test_gap\|env_issue", "affectedFiles": [...], "confidence": 0.0-1.0 }` |
+| Confirm | `confirmation.json` | `{ "approved": true\|false, "reason": "...", "revisedRootCause": "..." }` |
+| Fix | `fix-summary.json` | `{ "filesModified": [...], "testsAdded": [...], "description": "..." }` |
+| Retest | `retest-result.json` | `{ "previousFailures": [...], "retestResults": [...], "verdict": "pass\|fail" }` |
+
+### Screenshot Convention
+
+Screenshots for Tier 2 go in `<runId>/screenshots/` with names:
+`step-<N>-<description-slug>.png`
+
+---
+
+## 6. Priority Rules
+
+When selecting the next feature to process, the orchestrator follows this priority order:
+
+1. **`retesting`** - Finish in-progress retests first
+2. **`fixing`** - Complete in-progress fixes
+3. **`confirmed`** - Confirmed issues ready for fix
+4. **`triaged`** - Triaged issues ready for confirmation
+5. **`failed`** (retryCount < 3) - Failed features ready for triage
+6. **`queued`** - New features not yet checked
+
+Within the same priority level, prefer:
+- Features in smaller modules first (faster to clear a module completely)
+- Features with lower `retryCount`
+- Alphabetical by feature slug (deterministic ordering)
+
+---
+
+## 7. File Movement Rules
+
+### On `passed` -> `done`
+
+1. Copy feature file from `docs/features/unchecked/<module>/<feature>.md` to `docs/features/checked/<module>/<feature>.md`
+2. Update the status line in the file from `IMPLEMENTED` to `VERIFIED`
+3. Append a `## Verification` section with the run ID and date
+4. Remove the original from `unchecked/`
+5. Create the target module directory in `checked/` if it doesn't exist
+
+### On `not_implemented`
+
+1. Copy feature file from `docs/features/unchecked/<module>/<feature>.md` to `docs/features/unimplemented/<module>/<feature>.md`
+2. Update status from `IMPLEMENTED` to `PARTIALLY_IMPLEMENTED`
+3. Add notes about what was missing
+4. Remove the original from `unchecked/`
+
+### On `blocked`
+
+- Do NOT move the file
+- Add a `## Blocked` section to the feature file in `unchecked/` with the reason
+- The feature stays in `unchecked/` until a human unblocks it
+
+---
+
+## 8. Agent Contracts
+
+### stella-orchestrator
+- **Reads**: State files, feature files (to pick next work)
+- **Writes**: State files, moves feature files on pass/fail
+- **Dispatches**: Subagents with specific feature context
+- **Rule**: NEVER run checks itself; always delegate to subagents
+
+### stella-feature-checker
+- **Receives**: Feature file path, current tier, module info
+- **Reads**: Feature .md file, source code files, build output
+- **Executes**: File existence checks, `dotnet build`, `dotnet test`, Playwright CLI
+- **Returns**: Tier check results (JSON) to orchestrator
+- **Rule**: Read-only on feature files; never modify source code; never write state
+
+### stella-issue-finder
+- **Receives**: Check failure details, feature file path
+- **Reads**: Source code in the relevant module, test files, build errors
+- **Returns**: Triage JSON with root cause, category, affected files, confidence
+- **Rule**: Read-only; never modify files; fast analysis
+
+### stella-issue-confirmer

+
+## 9. Environment Prerequisites
+
+Before running Tier 1+ checks, ensure:
+
+### Backend (.NET)
+```bash
+# Verify .NET SDK is available
+dotnet --version  # Expected: 10.0.x
+
+# Verify the solution builds
+dotnet build src/StellaOps.sln --no-restore
+```
+
+### Frontend (Angular)
+```bash
+# Verify Node.js and Angular CLI
+node --version    # Expected: 22.x
+npx ng version   # Expected: 21.x
+
+# Build the frontend
+cd src/Web/StellaOps.Web && npm ci && npx ng build
+```
+
+### Playwright (Tier 2 only)
+```bash
+npx playwright install chromium
+```
+
+### Application Runtime (Tier 2 only)
+```bash
+# Start backend + frontend (if docker compose exists)
+docker compose -f devops/compose/docker-compose.dev.yml up -d
+
+# Or run individually
+cd src/Web/StellaOps.Web && npx ng serve &
+```
+
+If the environment is not available, Tier 2 checks should be marked `skipped`
+with `skipReason: "application not running"`.
+
+---
+
+## 10. Cost Estimation
+
+| Tier | Per Feature | 1,144 Features | Notes |
+|------|-------------|-----------------|-------|
+| Tier 0 | ~$0.01 | ~$11 | File existence only |
+| Tier 1 | ~$0.05 | ~$57 | Build + test |
+| Tier 2 | ~$0.50 | ~$165 (330 UI features) | Playwright + Opus |
+| Triage | ~$0.10 | ~$30 (est. 300 failures) | Sonnet |
+| Confirm | ~$0.15 | ~$30 (est. 200 confirmed) | Opus |
+| Fix | ~$0.50 | ~$75 (est. 150 fixes) | o3 |
+| Retest | ~$0.20 | ~$30 (est. 150 retests) | Opus |
+| **Total** | | **~$400** | Conservative estimate |
+
+Run Tier 0 first to filter out `not_implemented` features before spending on higher tiers.

After fixing edge IDs, this test should query a valid acme edge with a different tenant to actually test isolation. (2) The seeded explanation for 'ge:acme:artifact->component' uses EdgeExplanationFactory.FromSbomDependency (Reason=SbomDependency) even though InferReasonFromKind('builds') returns BuildArtifact — this is a design inconsistency between the seed data and the inference logic that the fixer should reconcile. (3) The comment on line 126 of the test file ('seeded edges include builds which maps to SbomDependency') is incorrect — 'builds' maps to BuildArtifact; however the QueryByReasonAsync test would still pass because it reads from the _explanations dictionary (which has SbomDependency for the seeded edges), not from InferReasonFromKind.",
