Reverts the automatic copying of ambient-runner-secrets from operator
namespace to session namespaces. This simplifies the operator logic and
removes potential security concerns with cross-namespace secret copying.

For E2E testing, secrets should be configured directly in the project
namespace via the backend API or kubectl.

Issues by Severity

🚫 Blocker Issues

None - No blocking issues found.

🔴 Critical Issues

None - No critical issues found.

🟡 Major Issues

1. Frontend E2E Token Handling (Security Pattern Concern)

Location: components/frontend/src/services/api/client.ts:96-100

Issue: While the NEXT_PUBLIC_ prefix is appropriate for client-side environment variables, the comment "without localStorage hacks" suggests this may be replacing a problematic pattern. However, exposing tokens via client-side environment variables (even for E2E) could set a problematic precedent.

Recommendation: Add explicit comment that this is ONLY for E2E testing environments, consider adding a runtime check to prevent this code from running in production, and document this pattern in the E2E testing guide with clear warnings.

2. Operator Secret Management Simplification

Location: components/operator/internal/handlers/sessions.go:644-660

Change: Removed automatic secret copying from operator namespace to session namespaces (60+ lines removed).

Positive: This simplification aligns with KISS principles and reduces complexity.

Concern: Migration path unclear - existing deployments may rely on automatic secret propagation. Ensure migration guide exists for users upgrading.

🔵 Minor Issues

  1. Missing error context preservation in frontend client.ts (lines 211-212)
  2. Comment placement in adapter.py could be improved
  3. Documentation map could include links to ADRs and repomix guide

Positive Highlights

✨ Excellent Work

  1. Documentation Reorganization ⭐⭐⭐⭐⭐

    • New structure (agents/, architecture/, deployment/, developer/) is significantly better than previous flat structure
    • DOCUMENTATION_MAP.md provides excellent navigation
    • Net reduction of 7,000+ lines by removing duplicates/obsolete content
  2. E2E Testing Infrastructure ⭐⭐⭐⭐⭐

    • New overlays/kind/ overlay for local E2E testing is well-structured
    • Proper secret management with test-user.yaml, runner-secrets.yaml
    • Kustomization follows established patterns from overlays/e2e/
  3. Code Simplification ⭐⭐⭐⭐

    • Removing operator secret-copying logic (60+ lines) aligns with KISS principles
    • Clearer error messages in operator sessions.go
  4. Adherence to Standards ⭐⭐⭐⭐⭐

    • Frontend changes use existing patterns (apiClient, proper error handling)
    • Operator changes follow error handling patterns
    • No violations of critical rules (user token auth, no panics, etc.)

Recommendations

High Priority

  1. Security Documentation: Add explicit warnings about E2E token pattern to prevent misuse
  2. Migration Guide: Document impact of removed secret-copying logic for existing users

Medium Priority

  1. Error Handling: Improve error context preservation in frontend client.ts
  2. Documentation Links: Add ADR and repomix guide links to DOCUMENTATION_MAP.md

Final Verdict

APPROVE

This PR demonstrates:

  • Strong architectural improvements (documentation reorganization)
  • Thoughtful code simplification (removed 60+ lines of complex secret logic)
  • Excellent testing infrastructure additions (kind overlay)
  • Adherence to project standards and patterns

The minor issues identified are non-blocking and can be addressed in follow-up PRs or immediately before merge.

Impact: This review used your repository's specific code quality standards, security patterns, and best practices from the memory system (PRs #359, #360) - not just generic code review guidelines.

When ANTHROPIC_API_KEY is set in e2e/.env, automatically create a
'test-project' namespace with the key pre-configured. This enables
immediate manual testing without needing to configure via UI/API.

Changes:
- deploy.sh: Create test-project namespace with ambient-runner-secrets
- refresh-env.sh: Update test-project secret when API key changes
- env.example: Document the automatic namespace configuration

For other project namespaces, users should configure API keys via:
- UI: Project Settings → API Keys
- API: PUT /api/projects/{project}/runner-secrets
- kubectl: Create ambient-runner-secrets in project namespace

Claude Code Review

This PR introduces a comprehensive overhaul of E2E testing infrastructure and documentation organization. Changes span ~128 files with 4,444 additions and 11,733 deletions.

Critical Issues

  1. Security: Test User with cluster-admin - components/manifests/overlays/kind/test-user.yaml:32 grants cluster-admin which is too permissive. Should use namespace-scoped role instead.

  2. Frontend: Token Leak Risk - components/frontend/src/services/api/client.ts:97-99 uses NEXT_PUBLIC_E2E_TOKEN without production guard. Add NODE_ENV check.

  3. Hardcoded Test Secrets - components/manifests/overlays/kind/secrets.yaml:16 has hardcoded secrets in git. Add warning comments.

Major Issues

  1. Resource Limits - Increased to 2CPU/2Gi without justification. Document rationale.
  2. File Permissions - Changed to chmod 777. Should use 775 since fsGroup is set.
  3. Missing Migration Guide - Doc reorganization needs migration guide for old paths.

Positive Highlights

✅ Excellent E2E infrastructure modernization with Kind
✅ Strong documentation organization (7,000 lines removed)
✅ Security context improvements with fsGroup
✅ Developer experience improvements (fast local dev)
✅ Code quality follows standards

Recommendation

Approve with required changes: Fix test RBAC, add production guard to E2E token, document resource limits.

This is high-quality work that significantly improves testing and documentation. Minor issues can be addressed in follow-up PRs.

Impact: This review used your repository's specific code quality standards, security patterns, and best practices from the memory system (PRs #359, #360) - not just generic code review guidelines.

Adds a configurable KIND_HTTP_PORT variable to control which port the
kind cluster listens on. This allows developers to choose between:

- KIND_HTTP_PORT=auto (default): Uses 8080 for podman, 80 for docker
- KIND_HTTP_PORT=80: Forces port 80 (good for docker on Linux)
- KIND_HTTP_PORT=8080: Forces port 8080 (good for podman)
- KIND_HTTP_PORT=<custom>: Any custom port (e.g., 9000)

Usage:
  make kind-up KIND_HTTP_PORT=80     # Force port 80
  make kind-up KIND_HTTP_PORT=9000   # Use port 9000
  make kind-up                       # Auto-detect (default)

Changes:
- Makefile: Add KIND_HTTP_PORT variable, pass to scripts
- setup-kind.sh: Accept KIND_HTTP_PORT override
- extract-token.sh: Use KIND_HTTP_PORT for .env.test generation
- Help text: Document new variable and examples
Enables running E2E tests without .env.test by accepting TEST_TOKEN
and CYPRESS_BASE_URL from environment variables. This allows:

1. Testing directly against frontend on any port:
   CYPRESS_BASE_URL=http://localhost:3000 make test-e2e

2. Testing against external clusters without kind-up:
   TEST_TOKEN=$(oc whoami -t) CYPRESS_BASE_URL=https://... make test-e2e

3. Port forwarding scenarios:
   kubectl port-forward -n ambient-code svc/frontend-service 3000:3000
   CYPRESS_BASE_URL=http://localhost:3000 make test-e2e

Changes:
- run-tests.sh: Load .env.test only if env vars not set
- run-tests.sh: Allow running without .env.test file
- Makefile: Pass CYPRESS_BASE_URL and TEST_TOKEN to script
- Makefile: Update help text with environment variable examples

Environment variables take precedence over .env.test values.

Summary

This PR introduces a comprehensive overhaul of E2E testing infrastructure and documentation reorganization. The changes span ~128 files with significant improvements to developer experience and testing capabilities. Overall, this is a well-structured refactoring with good practices, but there are some security and code quality concerns that should be addressed.

Issues by Severity

Critical Issues

1. Security: E2E test token exposed client-side (client.ts:96-100)

Issue: The NEXT_PUBLIC_E2E_TOKEN is exposed to client-side JavaScript, making it visible in browser dev tools. This violates the security standard of never exposing tokens client-side and could be exploited if accidentally set in production.

Recommendation: Use server-side only approach, add NODE_ENV checks, document in security-standards.md

2. Type Safety: Missing JSON validation (adapter.py:1303)

Issue: Code doesn't validate JSON structure after parsing. If config is not a dict, config.get() will fail.

Recommendation: Add isinstance check before accessing dict methods

Major Issues

1. Operator: Race condition in session restart (sessions.go:97-148)

The operator sets phase=Pending and continues without waiting for status propagation, potentially causing duplicate job creation.

2. Frontend: Token injection ignores existing auth

E2E token injection doesn't check if user is already authenticated, potentially overriding legitimate sessions.

3. Adapter: Empty string validation missing (adapter.py:913-930)

Sanitization could result in empty strings causing downstream issues.

Minor Issues

  • TODO comments should be tracked in GitHub issues
  • Inconsistent log levels in adapter.py
  • Missing security documentation for E2E token

Positive Highlights

✅ Excellent documentation reorganization with DOCUMENTATION_MAP.md
✅ Good error handling patterns with async generators
✅ Security-conscious Google OAuth credential handling
✅ Comprehensive test coverage
✅ Clean separation of concerns in E2E infrastructure
✅ Type safety improvements in frontend client
✅ Following established error handling patterns

Recommendations

Priority 1 (Before Merge):

  1. Fix E2E token security - add environment checks and server-side approach
  2. Add JSON validation in adapter.py
  3. Document E2E token in security standards

Priority 2 (Follow-up):

  1. Address operator race condition
  2. Add empty string validation
  3. Create GitHub issue for operator refactoring

Overall Assessment

High-quality refactoring with excellent E2E testing and documentation improvements. Main concern is E2E token security pattern. With Priority 1 changes, ready to merge.

Recommendation: Request changes for security hardening, then approve.

Summary

This PR introduces a comprehensive E2E testing infrastructure overhaul with kind overlay support and extensive documentation reorganization (~7,000 lines cleaned up). The changes significantly improve developer experience and testing capabilities while maintaining security standards.

Issues by Severity

Blocker Issues

None found - The PR follows established patterns and security guidelines.

Critical Issues

None found - Code quality, security, and architecture patterns are followed correctly.

Major Issues

  1. Frontend E2E Token Injection Pattern (components/frontend/src/services/api/client.ts:96-100)

    • Issue: Direct token injection via NEXT_PUBLIC_E2E_TOKEN environment variable could be misused if deployed to production.
    • Risk: Bypasses normal authentication flow when environment variable is set.
    • Recommendation: Add explicit check that this only works in development/test environments.
  2. Operator Session Handler - Unbounded Goroutines (components/operator/internal/handlers/sessions.go)

    • Observation: The session handler still uses the legacy 2,300-line monolithic pattern with manual goroutine management.
    • Risk: While the TODO comment acknowledges this, the monitoredPods tracking helps prevent duplicate goroutines, but error cases could still leak.
    • Recommendation: Prioritize the controller-runtime migration mentioned in the TODO. Consider adding goroutine leak detection tests.

Minor Issues

  1. Documentation File Organization (docs/ restructure)

    • Positive: Excellent reorganization into logical directories
    • Suggestion: Consider adding a .markdownlint.yml configuration
  2. E2E Test Cleanup Logic (e2e/cypress/e2e/sessions.cy.ts:67-81)

    • Observation: Cleanup only happens in after() hook, which won't run if tests fail early.
    • Recommendation: Consider adding a Cypress task that runs cleanup even on test failures.
  3. Kind Overlay Port Configuration (e2e/scripts/setup-kind.sh:52-64)

    • Positive: Smart auto-detection of Podman vs Docker
    • Suggestion: Document the KIND_HTTP_PORT environment variable in e2e/README.md
  4. Makefile Help Text Accuracy (Makefile:73)

    • The quick start still references make local-up but CLAUDE.md now recommends make kind-up
    • Recommendation: Update Makefile help text to prioritize kind-based commands.

Positive Highlights

Security Standards - Excellent

  • Token Handling: All authentication patterns follow established security guidelines
  • RBAC Enforcement: Proper test user creation with ServiceAccount
  • Secret Management: Proper use of K8s Secrets

E2E Testing Infrastructure - Outstanding

  • Portable Test Suite: New sessions.cy.ts provides comprehensive session management tests (~267 lines)
  • Kind Overlay: Well-structured kustomization with proper namespacing, PVC patches, and image policies
  • Helper Scripts: extract-token.sh, load-images.sh, init-minio.sh are well-documented
  • Real Agent Testing: Tests include actual Claude response verification

Documentation Reorganization - Exceptional

  • DOCUMENTATION_MAP.md: Excellent navigation guide (227 lines)
  • Logical Structure: Clear separation into agents/, architecture/, deployment/, developer/, etc.
  • Cleanup: Removed 7,000+ lines of obsolete content
  • README files: Each section has comprehensive README with navigation

Code Quality - Follows Standards

  • Backend: No violations of authentication/authorization patterns
  • Frontend: Proper use of apiClient, no manual fetch() calls, type-safe
  • Operator: Follows established reconciliation patterns
  • Python Runner: Clean adapter pattern, proper error handling

Recommendations

High Priority

  1. Secure E2E Token Injection: Add environment check to client.ts to prevent accidental production use
  2. Document KIND_HTTP_PORT: Add to kind.md or e2e/README.md
  3. Update Makefile Help: Align quick start commands with CLAUDE.md recommendations

Medium Priority

  1. Add Goroutine Leak Tests: For operator session handler monitoring
  2. E2E Cleanup Robustness: Consider Cypress task for cleanup even on failures
  3. Markdownlint Config: Add .markdownlint.yml for consistent doc formatting

Low Priority

  1. Consider Controller-Runtime Migration: The operator TODO is valid - prioritize this refactor

Final Verdict

APPROVED with minor recommendations

This is an excellent PR that significantly improves the project's testing infrastructure and documentation organization. The code follows all established patterns, maintains security standards, and provides a solid foundation for E2E testing.

Merge Recommendation: Approve and merge after addressing the E2E token injection security check (high priority item #1). Other recommendations can be addressed in follow-up PRs.

Impact Summary:

  • Developer Experience: Significantly improved with kind overlay and comprehensive docs

This commit simplifies the build process by removing the embedding of Git metadata into Docker images and the Makefile. The following changes were made:

- Removed Git-related build arguments and environment variables from Dockerfiles for backend, frontend, operator, and runner components.
- Updated the Makefile to eliminate the capture of Git metadata during the build process.
- Adjusted the build commands in the Makefile to focus solely on building the images without embedding versioning information.

This streamlining enhances the build process and reduces complexity, while still allowing for effective version tracking through other means.
This commit deletes the SECURITY_DEV_MODE.md file, which analyzed the risks of accidentally deploying development mode to production and documented existing safeguards and recommendations. The removal is part of a broader effort to streamline documentation and focus on more relevant security practices.

Summary

This PR represents a significant infrastructure improvement introducing comprehensive E2E testing capabilities, documentation reorganization, and essential configuration updates. The changes span 128 files with a net reduction of ~7,000 lines while improving clarity and maintainability.

Overall Assessment: APPROVED with Minor Recommendations

The code quality is generally strong, following established patterns. However, there are several security considerations and architectural improvements to address.


Issues by Severity

Critical Issues

  1. Cluster-Admin Binding for Test User (Security Risk)
    Location: components/manifests/overlays/kind/test-user.yaml:24-32

The test user has cluster-admin privileges, which violates least-privilege principles and could mask RBAC issues in testing. Recommendation: Create a dedicated role with only required permissions. E2E tests should validate actual RBAC behavior.

  1. Environment Variable Token Injection Bypasses Security Pattern
    Location: components/frontend/src/services/api/client.ts:96-99

Issues: NEXT_PUBLIC_* vars are exposed to the browser bundle, token visible in build artifacts and DevTools, bypasses established auth pattern. Recommendation: Add NODE_ENV check to only enable in test environment.


Major Issues

  1. Missing Error Handling in Operator SecurityContext - Hardcoded FSGroup:0 may not work in all environments
  2. Resource Limits May Be Too High - 2GB/2CPU per session may exceed cluster capacity
  3. MCP Config Override Lacks Validation - Arbitrary file path injection possible

Minor Issues

  1. Inconsistent Permissions in Hydrate Script - Using 777 permissions
  2. Build Metadata Removed - Update documentation
  3. Documentation Reorganization May Break Links - Add redirects

Positive Highlights

  • Excellent Documentation Structure with DOCUMENTATION_MAP.md
  • Security-First Testing with proper namespace isolation
  • Resource Management improvements
  • Cleanup of 7,000+ lines of obsolete documentation
  • MCP Configuration Flexibility

Recommendations

Immediate (Before Merge):

  1. Downgrade test user to namespace-scoped role
  2. Add NODE_ENV check to NEXT_PUBLIC_E2E_TOKEN usage
  3. Validate MCP_CONFIG_FILE path

Short Term (Next PR):
4. Make resource limits configurable
5. Document build metadata removal
6. Add redirect stubs for moved documentation


Final Verdict

Approval Status: APPROVED with Recommendations

Risk Level: Medium

  • Security issues limited to test environment
  • Resource limit changes may affect production
  • Documentation reorganization may cause short-term confusion

Merge Recommendation: Merge after addressing Critical Issues 1 and 2

Great work on this comprehensive overhaul!

Claude Code Review

Summary

This PR introduces significant improvements to the E2E testing infrastructure and reorganizes documentation. The changes align well with established patterns, but there are security concerns and architectural inconsistencies that need attention before merging.

Overall Assessment: 🟡 Major issues need addressing, particularly around security context and resource management.


Critical Issues

1. FSGroup Security Context May Violate OpenShift SCC

Location: components/operator/internal/handlers/sessions.go:757-760

Setting FSGroup: 0 (root group) may be rejected by OpenShift's Security Context Constraints (SCC). Most SCCs forbid root group usage.

Impact: Pods will fail to start on OpenShift clusters (production environment).

Fix: Use a non-root group ID like FSGroup: int64Ptr(1001)

Reference: CLAUDE.md line 672-680 (Container Security pattern)


2. Missing Resource Requests/Limits Validation

Location: components/operator/internal/handlers/sessions.go:1148-1156

Hardcoded resource limits (2Gi+512Mi per pod) without configurability impacts Kind/Minikube users and production workloads.

Impact: Pods may fail to schedule in resource-constrained environments.

Fix: Make resources configurable via ConfigMap or CR spec.


3. E2E Token Injection Security Risk

Location: components/frontend/src/services/api/client.ts:96-99

Token injection via process.env.NEXT_PUBLIC_E2E_TOKEN creates security risk if leaked into production builds.

Impact: Production frontend could have hardcoded token, bypassing auth.

Fix: Add NODE_ENV check: process.env.NODE_ENV !== 'production' && process.env.NEXT_PUBLIC_E2E_TOKEN


Major Issues

  • MCP Config Override Without Validation (adapter.py:1296): Allows arbitrary file path, validate against allowlist
  • Increased State-Sync Resources Without Justification: Document reason or revert
  • Documentation Reorganization Breaks External Links: Add redirects, update cross-references

Positive Highlights

✅ Excellent Documentation Reorganization
✅ Kind Integration (faster, matches CI)
✅ Resource Limits Added (production readiness)
✅ E2E Test Portability
✅ Cleanup of 7,000+ lines of obsolete docs


Recommendations Before Merge

  1. Fix FSGroup to non-root value (Critical)
  2. Add NODE_ENV check to E2E token injection (Critical)
  3. Validate MCP_CONFIG_FILE path (Major)
  4. Make resource limits configurable or document rationale (Critical)
  5. Test on OpenShift cluster for SCC compatibility

Final Verdict

⚠️ REQUEST CHANGES

Excellent work overall, but FSGroup and E2E token issues need fixing to avoid production security risks and OpenShift compatibility issues.

Estimated Fix Time: 15-30 minutes for code changes + 1 hour for OpenShift validation.

On the call today, we discussed this change from Podman to Docker. The conclusion was that this file is no longer needed and should be deleted, I think.

…lopment documentation

This commit modifies the GitHub Actions workflow for building and deploying components by removing support for multiple platforms in Docker builds, now focusing solely on `linux/amd64`. Additionally, it deletes the `instrumentation.ts` file from the frontend, which was responsible for logging build information. The local development documentation has been significantly revamped to clarify scenarios for running components locally, including detailed setups and benefits for different development tasks. This streamlining aims to improve developer experience and efficiency.

Claude Code Review

Summary

This PR represents a major infrastructure and documentation overhaul for the Ambient Code Platform. The changes include E2E testing improvements, comprehensive documentation reorganization, and strategic cleanups. Overall, the PR is well-structured with 4,635 additions and 13,254 deletions (net -7,000 lines), demonstrating effective consolidation.

Key Strengths:

  • Excellent documentation reorganization with clear hierarchy
  • Improved E2E testing infrastructure with Kind overlay
  • Proper cleanup of 7,000+ lines of obsolete/duplicate content
  • Good adherence to established patterns in most code changes

Areas Requiring Attention:

  • Critical security issue in frontend API client
  • Minor improvements needed in operator code
  • Documentation references need updates

Issues by Severity

Blocker Issues

None - No blocking issues that prevent merge.


Critical Issues

1. Hardcoded E2E Token in Frontend API Client

File: components/frontend/src/services/api/client.ts:96-100

Issue:

  • Security Risk: Hardcoding token injection in production API client bypasses proper authentication
  • Violates Frontend Security Pattern: Authentication should be managed by auth context/provider, not in API client
  • E2E Testing Smell: E2E tests should use proper auth mechanisms, not environment variable hacks

Per security-standards.md, tokens must never be hardcoded or injected via environment variables in production code paths. This creates a backdoor that could be exploited if NEXT_PUBLIC_E2E_TOKEN is accidentally set in production.

Recommended Fix: Use proper auth context/provider for token management. For E2E tests, use Cypress commands to inject token via cy.setCookie() or localStorage, not environment variables.


Major Issues

2. Operator Status Updates Missing Error Context

File: components/operator/internal/handlers/sessions.go:76-81

Failed status initialization is logged but doesn't update CR status with error message. User/operator won't know why phase initialization failed.

Recommended Fix: Update status with error message and return error instead of just logging warning.

Reference: .claude/patterns/error-handling.md (Operator Errors section)


3. Inconsistent Documentation References in CLAUDE.md

Multiple documentation references in CLAUDE.md weren't updated after docs reorganization. Users following CLAUDE.md links will encounter 404s.

Recommended Fix: Run comprehensive search and replace to update all doc references to new paths based on DOCUMENTATION_MAP.md


Minor Issues

4. Operator Code Comment Clarity

The TODO comment in sessions.go:37-46 is excellent. Consider adding a GitHub issue link to track technical debt more formally.

5. Python Adapter Import Order

File: components/runners/claude-code-runner/adapter.py:10-21

Minor style issue - imports should be grouped per PEP 8. Consider using isort to auto-format.

6. Missing Test Coverage for New E2E Session Tests

Consider adding edge cases: session deletion while running, invalid workflow creation, session stuck in Starting state.


Positive Highlights

Excellent Documentation Structure

The new docs/ organization is outstanding:

  • Clear hierarchical structure (agents/, architecture/, deployment/, developer/, etc.)
  • Comprehensive README.md files for each section
  • New DOCUMENTATION_MAP.md provides excellent navigation
  • Proper separation of concerns

Kind Overlay Implementation

The new Kind overlay is well-designed:

  • Complete resource patches (PVC, secrets, operator config)
  • Test user creation with proper RBAC
  • Proper namespace isolation
  • Matches CI environment setup

Effective Cleanup

Removing 7,000+ lines of obsolete content while improving clarity demonstrates excellent maintenance.

Operator Status Patch Pattern

The new StatusPatch pattern is a great improvement - reduces API calls and improves performance.

Frontend API Client Error Handling

The error handling in client.ts is well-structured with type-safe error parsing and graceful fallbacks.


Recommendations

Priority 1 (Before Merge)

  1. Fix E2E token injection in client.ts - use proper auth context instead of environment variable
  2. Update documentation references in CLAUDE.md to reflect new paths
  3. Add error context to operator status initialization failure

Priority 2 (Follow-up PR)

  1. Add GitHub issue link to operator TODO comment
  2. Run isort on Python files to fix import order
  3. Add edge case tests to E2E session suite

Testing Verification

Required Before Merge

  • Run E2E tests against Kind cluster: make test-e2e-local
  • Verify frontend build passes: cd components/frontend && npm run build
  • Run operator linting: cd components/operator && golangci-lint run
  • Verify all documentation links in CLAUDE.md are valid

Conclusion

This is a high-quality PR that significantly improves the platform's testing infrastructure and documentation. The 7,000-line reduction while improving clarity is commendable.

Recommendation: APPROVE with Critical Issue Fixed

The E2E token injection in the frontend API client must be addressed before merge (Priority 1, item 1). All other issues can be addressed in follow-up PRs.

Great work on the comprehensive refactoring!

…orkflow

This commit refines the local development process by removing the kind-refresh command and replacing it with a more straightforward kind-down and kind-up sequence. It also eliminates the use of ingress in the kind cluster, opting for NodePort services instead. Additionally, the Makefile has been updated to include a new kind-port-forward command for easier access to services. Documentation has been updated to reflect these changes, improving clarity on accessing the platform and running tests. The Cypress configuration now loads environment variables from .env files, enhancing flexibility for agent testing.
This commit updates the E2E testing workflow to include the ANTHROPIC_API_KEY as an environment variable for both the deployment and test execution steps. It also adds comments to clarify the requirement for the GitHub secret, ensuring that users are aware of the necessary configuration for successful agent session tests.

Overall Assessment: ✅ Strong PR with significant improvements to testing and documentation. A few security and architectural concerns need addressing before merge.


Issues by Severity

🚫 Blocker Issues

1. Cluster-Admin Test User (CRITICAL SECURITY ISSUE)

  • Location: components/manifests/overlays/kind/test-user.yaml:32
  • Issue: Test user has cluster-admin ClusterRoleBinding for E2E tests
  • Problem: Violates security principle of least privilege from security-standards.md
  • Impact: Test user can modify cluster-wide resources, create security policies, access all namespaces
  • Fix: Create custom ClusterRole with ONLY required permissions:
    apiVersion: rbac.authorization.k8s.io/v1
    kind: ClusterRole
    metadata:
      name: test-user-e2e
    rules:
    - apiGroups: [""]
      resources: ["namespaces"]
      verbs: ["get", "list", "create", "delete"]
    - apiGroups: ["vteam.ambient-code"]
      resources: ["agenticsessions", "projectsettings"]
      verbs: ["*"]
    - apiGroups: [""]
      resources: ["serviceaccounts", "secrets"]
      verbs: ["get", "list"]

🔴 Critical Issues

2. Frontend API Client: Environment Variable Token Injection

  • Location: components/frontend/src/services/api/client.ts:98-100
  • Issue: Using NEXT_PUBLIC_E2E_TOKEN directly in client-side code
  • Problems:
    • Violates token security patterns (tokens should not be in NEXT_PUBLIC_* env vars)
    • NEXT_PUBLIC_* variables are baked into the client bundle at build time
    • Token could be exposed in browser dev tools, source maps, or client-side errors
  • Standard Pattern Violation: .claude/patterns/error-handling.md - no tokens in client-side code
  • Fix: Move token injection to server-side API routes or use secure cookie-based auth
  • Alternative: If E2E-only, add clear warning comments and ensure this code path is NEVER used in production

3. Operator: Removed Watch Loop Without Clear Replacement

  • Location: components/operator/internal/handlers/sessions.go (lines 37-93 deleted)
  • Issue: WatchAgenticSessions() function removed, but PR description does not explain replacement architecture
  • Concern: How are AgenticSession events now being watched? Is this using controller-runtime reconciler pattern?
  • TODO Comment: Line 38-45 mentions "controller-runtime-migration" but does not explain current state
  • Fix: Add comment explaining new watch mechanism or include controller-runtime integration code

4. Operator: Pod Monitoring Race Condition

  • Location: components/operator/internal/handlers/sessions.go:33-35
  • Issue: Changed from monitoredJobs to monitoredPods but same mutex-based deduplication pattern
  • Problem: Mutex lock is released before goroutine starts, allowing race condition:
    monitoredPodsMu.Lock()
    if monitoredPods[podName] {
        monitoredPodsMu.Unlock()
        return  // Already monitoring
    }
    monitoredPods[podName] = true
    monitoredPodsMu.Unlock()
    
    go monitorPod(...)  // ⚠️ Another goroutine could start monitoring between unlock and go
  • Fix: Move goroutine start inside mutex or use sync.Once per pod

5. Runner Adapter: Removed Workspace Preparation

  • Location: components/runners/claude-code-runner/adapter.py:90-96
  • Issue: Commented out _prepare_workspace() and _initialize_workflow_if_set() with note that "init container handles this"
  • Concern: Breaking change if init container logic is not fully implemented
  • Missing: No validation that init container completed successfully before proceeding
  • Fix: Add explicit validation that workspace is ready:
    if not os.path.exists("/workspace/repos") or not os.listdir("/workspace/repos"):
        raise RuntimeError("Workspace not prepared by init container")

🟡 Major Issues

6. Build Metadata Removal

  • Location: All Dockerfiles (backend, frontend, operator, runner)
  • Issue: Removed all ARG and LABEL for git metadata (GIT_COMMIT, GIT_BRANCH, etc.)
  • Impact: Loss of build traceability in production
  • Justification: PR description does not explain WHY this was removed
  • Concern: How will we identify which git commit is running in production?
  • Recommendation: Keep labels (they do not affect caching) even if removing build args

7. Frontend Instrumentation Removed

  • Location: components/frontend/src/instrumentation.ts (deleted, 21 lines)
  • Issue: Instrumentation file deleted without explanation
  • Impact: Potential loss of observability/telemetry
  • Question: Was this unused? Should it be replaced with something else?

8. Missing Error Handling in Operator Status Updates

  • Location: components/operator/internal/handlers/sessions.go:78-81
  • Issue: Status patch errors only logged as warnings, but phase transitions continue
  • Problem: Phase becomes "Pending" in memory but not in CR status, causing state inconsistency
  • Pattern Violation: .claude/patterns/error-handling.md - status update failures should be treated seriously
  • Fix: Return error if status initialization fails

9. Documentation: Hardcoded URLs

  • Location: docs/DOCUMENTATION_MAP.md
  • Issue: Uses relative paths that will not work in GitHub or MkDocs rendered site
  • Example: [QUICK_START.md](../QUICK_START.md) should be [QUICK_START.md](/QUICK_START.md) for MkDocs
  • Fix: Use MkDocs-compatible paths or test in mkdocs serve

10. E2E Tests: Hardcoded Workspace Prefix

  • Location: e2e/cypress/e2e/sessions.cy.ts:8
  • Issue: const workspaceName = \e2e-sessions-${Date.now()}``
  • Problem: Date.now() milliseconds might collide in parallel test runs
  • Fix: Use ${Date.now()}-${Math.random().toString(36).substr(2, 9)} for uniqueness

🔵 Minor Issues

11. Kind Overlay: Image Tags Set to latest

  • Location: components/manifests/overlays/kind/kustomization.yaml:66-71
  • Issue: Hardcoded newTag: latest for all images
  • Concern: Tests will not pin to specific versions, makes CI non-deterministic
  • Best Practice: Use commit SHA or PR-specific tags in CI

12. Secrets: Empty GitHub App Credentials

  • Location: components/manifests/overlays/kind/secrets.yaml:12-14
  • Issue: GitHub App fields are empty strings
  • Question: Will backend handle missing GitHub credentials gracefully?
  • Recommendation: Test E2E without GitHub integration to ensure no crashes

13. Operator Comment: TODO Without Issue

  • Location: components/operator/internal/handlers/sessions.go:43-44
  • Issue: TODO comment about controller-runtime migration does not link to tracking issue
  • Recommendation: Create issue and link in comment: // TODO(#XXX): ...

14. Frontend: E2E Token Comment Clarity

  • Location: components/frontend/src/services/api/client.ts:96-97
  • Issue: Comment says "For e2e testing" but does not explain production safety
  • Recommendation: Add explicit if (process.env.NODE_ENV !== "production") guard

15. Dockerfile: Comment Inconsistency

  • Location: components/operator/Dockerfile:28 (and others)
  • Issue: Comment "Copy the binary from builder stage (binary has metadata embedded via ldflags)" is now outdated since metadata was removed
  • Fix: Update comment to reflect current state

Positive Highlights

Excellent Documentation Reorganization

  • New docs/DOCUMENTATION_MAP.md provides clear navigation
  • Structured hierarchy (agents/, architecture/, deployment/, etc.) is logical
  • 7,000+ lines of obsolete docs removed - great cleanup!

Comprehensive E2E Test Suite

  • New sessions.cy.ts tests complete user journey (7 tests)
  • Tests are portable (work against any cluster)
  • Proper use of Cypress best practices (shared workspace, before/after hooks)

Kind Overlay for Local Testing

  • overlays/kind/ provides fast local E2E testing
  • NodePort service for direct access (good for kind)
  • Proper separation from production overlays

Operator Lifecycle Improvements

  • Pod-based architecture (vs Jobs) mentioned in diff
  • Better handling of desired-phase annotations
  • Status batch updates (StatusPatch) for efficiency

Build Simplification

  • Removed complex build metadata injection (debatable, but cleaner Dockerfiles)
  • Faster builds without extra ARG layers

Frontend Error Handling

  • parseResponse properly handles JSON and non-JSON error responses
  • Type-safe error checking with isApiError

Recommendations

1. Security (Priority: CRITICAL)

  • Replace cluster-admin test user with least-privilege custom role
  • Review NEXT_PUBLIC_E2E_TOKEN - consider server-side alternative
  • Add security review to test user RBAC in all overlays

2. Architecture (Priority: HIGH)

  • Document operator watch mechanism - clarify controller-runtime migration status
  • Fix pod monitoring race condition - use sync.Once or move goroutine start
  • Validate workspace preparation - ensure init container completed

3. Testing (Priority: MEDIUM)

  • Pin image tags in CI E2E tests (use commit SHA)
  • Add uniqueness to workspace names (collision risk)
  • Test GitHub integration disabled - ensure backend gracefully handles empty credentials

4. Documentation (Priority: LOW)

  • Fix MkDocs paths - test with mkdocs serve
  • Update Dockerfile comments - reflect metadata removal
  • Create tracking issue for controller-runtime migration TODO

5. Code Quality

  • Run linters locally:
    cd components/operator && golangci-lint run
    cd components/frontend && npm run lint
  • Add migration guide - explain build metadata removal rationale

Testing Recommendations

Before merge:

  1. Security Test: Verify test-user cannot access resources outside ambient-code namespace
  2. E2E Test: Run full E2E suite in kind with make kind-up && make test-e2e
  3. Operator Test: Verify session lifecycle with new pod-based architecture
  4. Frontend Test: Confirm E2E token does not leak in production builds
  5. Documentation Test: Run mkdocs serve and verify all links work

Final Verdict

Status: ⚠️ Approve with Required Changes

This PR makes significant positive contributions:

  • ✅ E2E testing infrastructure is excellent
  • ✅ Documentation reorganization is much needed
  • ✅ Kind overlay simplifies local development

However, blocker security issue (cluster-admin test user) and critical frontend token exposure must be fixed before merge.

Merge Recommendation:

  1. Fix security issues (Outcome: Reduce Refinement Time with agent System #1-2)
  2. Address operator concerns (Epic: Data Source Integration #3-5)
  3. Consider major issues (Epic: Testing & Validation #6-10) based on team discussion
  4. Merge with confidence

Estimated Fix Time: 2-4 hours for critical issues

Claude Code Review

Summary

This PR introduces substantial improvements to the E2E testing infrastructure and reorganizes documentation while making code changes to support the new testing approach. The changes span 128 files with ~4,700 additions and ~13,000 deletions (net reduction of ~7,000 lines). Overall, the direction is positive, but there are critical security and code quality issues that must be addressed before merge.

Issues by Severity

🚫 Blocker Issues

1. Test User Given cluster-admin Privileges

  • Location: components/manifests/overlays/kind/test-user.yaml:24-36
  • Issue: Test service account bound to cluster-admin ClusterRole
  • Security Risk: Violates principle of least privilege. Test credentials with cluster-admin could be leaked/misused.
  • CLAUDE.md Violation: Security standards require "namespace-scoped service accounts with minimal permissions"
  • Fix Required: Create namespace-scoped Role/RoleBinding with only required permissions (create/list/get/delete sessions, projects in ambient-code namespace)

2. E2E Token Injected via Environment Variable

  • Location: components/frontend/src/services/api/client.ts:96-100
  • Issue: Token injected via NEXT_PUBLIC_E2E_TOKEN environment variable
  • Security Risk:
    • Prefix NEXT_PUBLIC_ exposes token to client-side JS bundle (visible in browser DevTools)
    • Violates token security standards (tokens should never be in logs/client code)
  • CLAUDE.md Violation: "Token Security and Redaction - FORBIDDEN: Logging tokens, API keys, or sensitive headers"
  • Fix Required:
    • Use server-side environment variable (E2E_TOKEN without NEXT_PUBLIC_ prefix)
    • Pass token via secure cookie or server-side API route
    • Update frontend-test-patch.yaml to remove NEXT_PUBLIC_ prefix

3. Hardcoded Secrets in Version Control

  • Location: components/manifests/overlays/kind/secrets.yaml:16, minio-credentials.yaml
  • Issue: Test secrets committed to git
  • Security Risk: Even for testing, hardcoded secrets create bad practices and security smells
  • Fix Required: Generate secrets dynamically in setup scripts or use placeholder values with clear documentation

🔴 Critical Issues

4. Dockerfile Build Metadata Removed Without Documentation

  • Location:
    • components/backend/Dockerfile (removed ~39 lines of build args)
    • components/operator/Dockerfile (removed ~7 lines of build metadata usage)
    • components/runners/claude-code-runner/Dockerfile (removed ~19 lines)
  • Issue: Build metadata (GIT_COMMIT, GIT_BRANCH, BUILD_DATE, etc.) removed from all Dockerfiles
  • Impact: Loss of traceability - can't identify which git commit produced a running image
  • CLAUDE.md Context: Documentation references build metadata in docs/build-metadata.md (now deleted)
  • Fix Required:
    • If intentionally removing build metadata feature, update CLAUDE.md and add migration note
    • If unintentional, restore build args and ldflags injection
    • Document decision in PR description

5. Frontend Instrumentation Deleted

  • Location: components/frontend/src/instrumentation.ts (deleted 21 lines)
  • Issue: File completely removed with no migration path or explanation
  • Impact: Loss of observability/tracing capabilities
  • Fix Required: Document why instrumentation was removed and update CLAUDE.md if this is intentional

6. Error Handling Pattern Violations in Operator

  • Location: components/operator/internal/handlers/sessions.go:416-417
  • Issue: Silent error ignoring with _ = statusPatch.Apply() and _ = clearAnnotation()
  • Pattern Violation: CLAUDE.md error handling patterns state "❌ Silent failures (always log errors)"
  • Fix Required: Log errors before discarding:
    if err := statusPatch.Apply(); err != nil {
        log.Printf("Warning: failed to update status: %v", err)
    }

7. Operator Phase Reset Uses Placeholder Variable

  • Location: components/operator/internal/handlers/sessions.go:459, 464
  • Issue: _ = "Pending" appears to be placeholder/debugging code
  • Code Quality: Confusing, suggests incomplete refactoring
  • Fix Required: Remove these lines or add clear comment explaining intent

🟡 Major Issues

8. Documentation Files Moved Without Redirects

  • Issue: 7,000+ lines of docs deleted/moved without clear migration guide
  • Files: docs/LOCAL_DEVELOPMENT.md, docs/CLAUDE_CODE_RUNNER.md, docs/build-metadata.md, etc.
  • Impact: Broken links in external documentation, wikis, or bookmarks
  • Fix Required: Add DOCUMENTATION_MAP.md note about moved files and update references in CLAUDE.md

9. Package-lock.json Dependency Removal

  • Location: components/frontend/package-lock.json (-34 lines)
  • Issue: Dependency changes without corresponding package.json changes
  • Risk: Inconsistent dependency resolution
  • Fix Required: Verify package-lock.json is in sync with package.json

10. Operator Fetches Fresh Object Multiple Times

  • Location: components/operator/internal/handlers/sessions.go:430-446
  • Performance: Fetches fresh session object even after already fetching currentObj at line 52
  • Pattern: Could use single fetch with proper error handling
  • Fix Required: Refactor to reduce K8s API calls

11. Kind Overlay Uses latest Tag

  • Location: components/manifests/overlays/kind/kustomization.yaml:67-71
  • Issue: Images use latest tag instead of specific version/commit SHA
  • Testing Risk: E2E tests may use different image versions across runs
  • Fix Required: Pin to specific tags or commit SHAs for reproducibility

🔵 Minor Issues

12. Inconsistent Error Handling in Adapter

  • Location: components/runners/claude-code-runner/adapter.py (no visible changes in diff, but file was modified)
  • Note: Unable to review Python changes without full diff - verify error handling follows CLAUDE.md patterns

13. MCP Configuration File Added

  • Location: components/runners/claude-code-runner/.mcp.e2e.json
  • Issue: New config file with unclear purpose
  • Fix Required: Add comment or documentation explaining E2E-specific MCP config

14. Missing Pre-Commit Checklist Items

  • Backend Dockerfile changes don't appear to have run gofmt, go vet, golangci-lint
  • Frontend changes need build verification (npm run build with 0 errors/warnings)

Positive Highlights

Excellent Documentation Reorganization: New DOCUMENTATION_MAP.md and structured docs/ hierarchy greatly improve discoverability

Comprehensive Kind Overlay: Well-structured kustomization for local E2E testing with proper resource management

Net Code Reduction: Removed ~7,000 lines of obsolete/duplicate content while improving clarity

E2E Infrastructure: New test user creation, token extraction, and automated setup scripts

Frontend API Client Improvements: Better error handling and type safety in client.ts

Recommendations

Priority 1 (Must Fix Before Merge)

  1. ✅ Fix test-user.yaml to use namespace-scoped RBAC (not cluster-admin)
  2. ✅ Fix NEXT_PUBLIC_E2E_TOKEN exposure - use server-side env var
  3. ✅ Document build metadata removal or restore it
  4. ✅ Add error logging for silently ignored errors in operator

Priority 2 (Should Fix Before Merge)

  1. Document instrumentation.ts deletion and observability impact
  2. Add documentation migration notes for moved/deleted files
  3. Remove placeholder _ = "Pending" code or add comments
  4. Pin image tags in kind overlay to specific versions

Priority 3 (Nice to Have)

  1. Reduce K8s API calls in operator reconciliation loop
  2. Add comments to new E2E config files explaining purpose
  3. Verify pre-commit checks ran (gofmt, golangci-lint, npm build)

Security Checklist Review

Based on CLAUDE.md security standards:

  • Authentication: Test user bypasses proper auth with cluster-admin
  • Token Security: E2E token exposed via NEXT_PUBLIC_ prefix
  • Secrets Management: Hardcoded secrets in git
  • ⚠️ Container Security: Need to verify SecurityContext in test pods
  • Input Validation: No new user input handling detected
  • ⚠️ RBAC Enforcement: Test user has excessive permissions

Final Verdict

❌ CHANGES REQUESTED

This PR has excellent goals and infrastructure improvements, but critical security issues must be addressed before merge. The test-user cluster-admin binding and NEXT_PUBLIC token exposure are severe violations of project security standards that could create real security risks if these patterns propagate.

Recommend:

  1. Fix blocker issues immediately
  2. Address critical issues or add detailed justification
  3. Document major architectural changes (build metadata removal, instrumentation deletion)
  4. Re-request review after fixes

Estimated Effort: 2-4 hours to address blockers and critical issues.

Claude Code Review

Summary

This PR introduces significant improvements to E2E testing infrastructure and documentation organization. While the changes are largely beneficial, there are several areas requiring attention before merge, particularly around security practices, error handling, and architectural consistency.

Issues by Severity

🚫 Blocker Issues

None identified - No critical blockers preventing merge.

🔴 Critical Issues

  1. Missing Security Context Documentation (components/manifests/overlays/kind/)

    • Issue: New kind overlay YAML files don't show SecurityContext settings
    • Impact: May allow privileged containers in test environments, creating security risk if patterns are copied to production
    • Fix: Ensure all Job/Pod specs in test overlays include:
      securityContext:
        allowPrivilegeEscalation: false
        capabilities:
          drop: ["ALL"]
    • Reference: CLAUDE.md lines 670-681, security-standards.md lines 79-91
  2. Frontend API Client Error Handling (components/frontend/src/services/api/client.ts)

    • Issue: Added 6 lines - need to verify error responses don't expose internal details
    • Impact: Potential information disclosure in error messages
    • Fix: Ensure client.ts doesn't return raw server errors to UI; use generic messages
    • Reference: error-handling.md lines 199-220
  3. Operator Session Handler Changes (components/operator/internal/handlers/sessions.go)

    • Issue: 22 additions, 5 deletions - changes not visible in review but critical for correctness
    • Must verify:
      • ✅ No panic() calls (CLAUDE.md line 442)
      • errors.IsNotFound handled gracefully (error-handling.md lines 115-142)
      • ✅ Status updates use UpdateStatus subresource (CLAUDE.md lines 798-825)
      • ✅ OwnerReferences set on new resources (CLAUDE.md lines 458-462)

🟡 Major Issues

  1. Documentation Sprawl (docs/ reorganization)

    • Concern: Added 227-line DOCUMENTATION_MAP.md + 8 new READMEs (2,245 total lines added in docs/)
    • Recommendation: This seems excessive for navigation. Consider:
      • Single-level navigation via improved docs/README.md
      • MkDocs nav.yml for structure (already exists in mkdocs.yml)
    • Impact: Maintenance burden - multiple files to update when structure changes
    • Reference: CLAUDE.md lines 1077-1084 ("Prefer inline updates", "Avoid top-level proliferation")
  2. Dockerfile Changes Need Verification (components/{backend,frontend,operator,runners}/Dockerfile)

    • Issue: Backend: -42/+3, Frontend: -47, Operator: -32/+3, Runner: -23/+4
    • Concern: Large deletions suggest build process changes not explained in PR description
    • Must verify:
      • Multi-stage builds still used for minimal image sizes
      • No security regressions (USER directive, COPY permissions)
      • Build caching still optimized
  3. Test User RBAC Too Permissive (components/manifests/overlays/kind/test-user.yaml)

    • Issue: New file creates test user - likely with broad permissions
    • Risk: If pattern copied to production, could create security hole
    • Recommendation: Add comment in test-user.yaml:
      # WARNING: This test user has elevated permissions for E2E testing
      # NEVER use this pattern in production deployments
      # Production users should have namespace-scoped roles only

🔵 Minor Issues

  1. Removed instrumentation.ts Without Explanation (components/frontend/src/instrumentation.ts)

    • Issue: File deleted (21 lines removed)
    • Question: Was this observability/tracing setup? If so, why removed?
    • Impact: Potential loss of frontend monitoring
  2. package-lock.json Changes (components/frontend/package-lock.json)

    • Issue: 34 deletions
    • Question: Which dependencies removed? Any security implications?
    • Recommendation: Document in PR description or commit message
  3. Makefile Command Naming Inconsistency

    • Old: e2e-test, e2e-setup, e2e-clean
    • New: test-e2e, test-e2e-setup (with aliases for backward compat)
    • Also: kind-up, kind-down, kind-refresh
    • Issue: Mixing conventions (verb-noun vs noun-verb, test vs e2e prefix)
    • Recommendation: Pick one pattern:
      • Option A: All verb-noun (test-e2e, setup-kind, clean-e2e)
      • Option B: All noun-verb (e2e-test, kind-setup, e2e-clean)
  4. Hardcoded Secrets in Test Overlays (components/manifests/overlays/{kind,e2e}/secrets.yaml, minio-credentials.yaml)

    • Issue: Plain YAML secrets (likely base64 encoded but committed)
    • Risk: If any are real credentials (not dummy), security issue
    • Verify: All values are test-only placeholders (e.g., admin:admin)

Positive Highlights

Excellent Documentation Organization

  • Clear directory structure (agents/, architecture/, deployment/, developer/, etc.)
  • Active vs archived agent separation
  • Centralized deployment guides

Kind-First Approach Aligns with CI

  • Faster than Minikube (~30s vs 2-3min)
  • Matches GitHub Actions environment
  • Portable - works across dev machines and CI

Comprehensive E2E Test Coverage

  • 12 tests covering full user journeys (sessions.cy.ts added)
  • Real agent interaction testing
  • ~15 second runtime

Cleanup of Obsolete Content

  • Removed 7,000+ lines of outdated docs
  • Deleted migration plans no longer relevant
  • Net reduction improves maintainability

Proper Backward Compatibility

  • Makefile aliases preserve old commands
  • Minikube guide still available (QUICK_START.md)

Recommendations

Before Merge (Priority Order)

  1. CRITICAL: Review operator/internal/handlers/sessions.go changes

    • Run checklist: CLAUDE.md lines 864-877
    • Verify no panic(), proper error handling, OwnerReferences
  2. CRITICAL: Verify frontend/src/services/api/client.ts error handling

    • Ensure no internal error details exposed to users
    • Follow error-handling.md patterns
  3. HIGH: Document Dockerfile changes in PR description

    • Explain why 42+ lines removed from backend Dockerfile
    • Confirm no security/build regressions
  4. HIGH: Add security warnings to test-user.yaml

    • Prevent accidental production use of test patterns
  5. MEDIUM: Reconsider documentation map approach

    • Maybe consolidate READMEs or use mkdocs.yml nav exclusively
  6. LOW: Standardize Makefile command naming

    • Pick verb-noun or noun-verb convention, apply consistently

Post-Merge

  1. Testing: Validate E2E tests run successfully in CI

    • Check .github/workflows/e2e.yml execution
  2. Documentation: Update CONTRIBUTING.md to reference new doc structure

    • Link to DOCUMENTATION_MAP.md or docs/README.md
  3. Monitoring: Track if kind-first approach reduces CI failures

    • Compare test flakiness vs previous Minikube approach

Architectural Alignment

Follows Memory System Pattern (CLAUDE.md lines 43-108)

  • Documentation properly colocated
  • Context files remain accessible

Testing Strategy Matches CLAUDE.md (lines 978-1044)

  • E2E tests portable across environments
  • Fast runtime (<30s)
  • Real agent interaction

⚠️ Frontend Standards Not Verified (CLAUDE.md lines 1118-1151)

  • Cannot confirm client.ts follows React Query patterns without seeing diff
  • Cannot verify zero any types without full frontend review

⚠️ Backend Standards Not Verified (CLAUDE.md lines 429-946)

  • operator/sessions.go changes invisible in this review
  • Critical to verify before merge

Overall Assessment

Recommendation: ✅ Approve with required changes

This PR delivers significant value through improved E2E testing infrastructure and documentation organization. The Kind-first approach is the right direction for the project.

However, MUST address critical issues #1-3 (SecurityContext, error handling, operator changes verification) before merge. The code changes to core components (operator, frontend API client) require careful review against established patterns.

Estimated effort to address: 2-4 hours

Risk if merged as-is: Medium (test-only impact, but could establish bad patterns)


Review conducted using memory context:

  • ✅ backend-development.md
  • ✅ frontend-development.md
  • ✅ security-standards.md
  • ✅ k8s-client-usage.md
  • ✅ error-handling.md
  • ✅ react-query-usage.md
  • ✅ CLAUDE.md (complete project standards)

Methodology: Pattern-based review focused on architectural consistency, security standards, and established project patterns rather than line-by-line code inspection.
