PR Review Report: PR #20 - AK.Web.Gen2

Executive Summary

This PR implements critical authentication fixes for the PMS micro-frontend, introducing a dynamic AuthLink Apollo middleware to resolve stale JWT token issues. It also adds identity bootstrapping for fresh logins and implements a Strategy pattern for KPI data loading. While the core changes are architecturally sound and address real security concerns, there are test hygiene issues and commented-out code that need resolution before merge.

Overall Assessment: The AuthLink implementation is a critical security fix that addresses a fundamental flaw where static context was evaluated once at startup before token exchange completed. The Strategy pattern implementation for KPI data loading demonstrates good separation of concerns.

Critical Findings

CRITICAL: AuthLink Implementation - Security Fix

File: projects/pms/src/app/core/interceptors/auth-link.ts (NEW)

The Problem Being Fixed: The previous implementation used defaultOptions.context which was evaluated once at config time before the token exchange completed. This resulted in stale/empty Authorization headers on GraphQL requests after fresh login.

The Solution:

// AuthLink reads token dynamically from localStorage on EACH request
export class AuthLink extends ApolloLink {
    private static request(operation: Operation, forward?: NextLink) {
        const accessToken = AuthLink.getAccessToken(); // Fresh read every time
        if (accessToken) {
            operation.setContext({
                headers: {
                    ...operation.getContext()['headers'],
                    Authorization: `Bearer ${accessToken}`,
                },
            });
        }
        return forward ? forward(operation) : null;
    }
}

Applied To All Apollo Clients:

Default client (PMS GraphQL)
Named clients: pms, hrms, dpt, orchestrator

Security Considerations:

Properly guards against SSR (typeof window === 'undefined')
Handles private browsing mode gracefully (try/catch around localStorage)
Uses ACCESS_TOKEN_KEY constant for consistent key naming

Recommendation: APPROVED - This is a critical security fix that resolves authentication race conditions.

HIGH: Identity Service Bootstrap

File: projects/pms/src/app/core/services/identity.service.ts

Changes:

Added identityReady$ BehaviorSubject to signal when identity context is initialized
Implements bootstrapIdentityForFreshLogin() method
Dashboard component now waits for identityReady$ before loading data

Code Pattern:

// DRR-2026-02-20: Bootstrap identity on fresh login
if (!this.targetIdentityContext$.value) {
    this.bootstrapIdentityForFreshLogin();
} else {
    this.identityReadySubject$.next(true);
}

Impact: Prevents "not authorized" errors on fresh login by ensuring identity context is established before API calls.

Recommendation: APPROVED - Properly handles the identity initialization race condition.

MEDIUM: Strategy Pattern for KPI Data Loading

New Files:

projects/pms/src/app/features/setting-kpi/strategies/kpi-data-loading.strategy.ts
projects/pms/src/app/features/setting-kpi/strategies/settings-kpi.strategy.ts
projects/pms/src/app/features/setting-kpi/strategies/review-kpi.strategy.ts
projects/pms/src/app/features/setting-kpi/strategies/monitoring-kpi.strategy.ts

Implementation: Abstract strategy class with three concrete implementations:

Strategy	Behavior
`SettingsKPIStrategy`	Returns empty array if no job position, else fetches by hierarchy
`ReviewKPIStrategy`	Same as Settings - returns empty array if no job position
`MonitoringKPIStrategy`	Always fetches ALL KPIs (admin/HR only) using new `kpiDetailsForMonitoringAll` query

New GraphQL Query:

query KpiDetailsForMonitoringAll {
    kpiDetailsForMonitoringAll { ... }
}

Recommendation: APPROVED - Clean separation of concerns, properly documented with DRR reference.

WARNING: Test File Hygiene Issues

Issue 1: Commented-Out Test Code (Do Not Merge)

File: projects/pms/src/app/core/services/auth-logout-integration.service.spec.ts

afterEach(() => {
    // Restore window.location
    // window.location = originalWindowLocation;  // <-- COMMENTED OUT
});

File: projects/pms/src/app/features/competency/components/assessment/self-assessment/self-assessment.component.spec.ts

it('should hide dialog', () => {
    component.showConfirmDialog = true;
    // component.cancelSubmission();  // <-- COMMENTED OUT
    expect(component.showConfirmDialog).toBeFalse();
});

Recommendation: Either restore the code or delete the test. Commented-out code should not be committed.

Issue 2: Integration Test Deletion

Deleted Files:

projects/pms/src/app/features/kpi-approval/tests/index.ts
projects/pms/src/app/features/kpi-approval/tests/integration-test-utils.ts
projects/pms/src/app/features/kpi-approval/tests/kpi-approval.integration.spec.ts
projects/pms/src/app/features/kpi-approval/tests/test-config.ts

Impact: Integration test coverage removed. Verify this is intentional and that E2E tests (Playwright) provide adequate coverage.

Issue 3: Multiple Spec Files Deleted

Deleted Spec Files:

kpi-approval.service.spec.ts
kpi-monitoring.component.spec.ts
kpi-review-history.component.spec.ts
kpi-settings.component.spec.ts
kpi-submission-history.component.spec.ts
kpi.service.spec.ts

Recommendation: Verify these deletions are intentional. If tests were failing and removed rather than fixed, this reduces test coverage.

WARNING: Service Bug Fix

File: projects/pms/src/app/features/kpi-approval/services/kpi-approval.service.ts

Fix: Added null check for approverId to avoid GraphQL validation errors:

// Return empty array if no current employee (avoids GraphQL validation error)
if (!approverId) {
    this.pendingApprovalsSubject$.next([]);
    return new BehaviorSubject<ApprovalStatus[]>([]).asObservable();
}

Also added error propagation:

catchError(error => {
    const errorMessage = this.extractError(error);
    this.errorSubject$.next(errorMessage);  // <-- Now propagates to error$
    return throwError(() => errorMessage);
})

Recommendation: APPROVED - Proper defensive programming.

INFO: Duplicate Test Code Fixed

File: projects/pms/src/app/features/settings/components/workflow-configuration/status-color-mapping.service.spec.ts

Issue: Multiple duplicate lines removed:

// Before (duplicate):
const op = controller.expectOne(UPSERT_GENERAL_SETTINGS);
const op = controller.expectOne(UPSERT_GENERAL_SETTINGS);  // Duplicate removed

// Before (duplicate test definition):
it('should return value string on successful save', done => { ... });
it('should return value string on successful save', done => { ... });  // Duplicate removed

Recommendation: APPROVED - Code cleanup.

Code Quality Assessment

Positive Patterns

DRR Comments: Design Rationale Records included (DRR-2026-02-20)
JSDoc Documentation: Comprehensive comments on AuthLink and strategies
Error Handling: Proper try/catch around localStorage access
RxJS Patterns: Proper use of BehaviorSubject, takeUntilDestroyed
Dependency Injection: Modern inject() function used instead of constructor injection

Areas for Improvement

Test Coverage: Significant test file deletions need justification
Commented Code: Two instances of commented-out test code should be resolved
GraphQL Context: AuthLink removes need for authService.getAuthContext() in defaultOptions but it's still used in getAllKPIsForMonitoring() - verify consistency

Architecture Compliance

Principle	Status	Notes
Feature-Based Architecture	PASS	Changes confined to features/ directory
Standalone Components	PASS	No NgModule changes detected
Strategy Pattern	PASS	Proper abstraction for KPI loading
Apollo Link Chain	PASS	AuthLink -> CustomerIdLink -> TargetIdentityLink -> HttpLink
Barrel Exports	PASS	strategies/index.ts properly exports all strategies

Security Review

Check	Status	Notes
Token Storage	PASS	Uses localStorage with proper guards
SSR Safety	PASS	Checks `typeof window` before localStorage access
Private Mode	PASS	try/catch handles localStorage unavailability
Authorization Header	PASS	Proper `Bearer ${token}` format
Token Refresh	N/A	Not in scope - handled by token exchange initializer

Performance Implications

AuthLink Overhead: Minimal - localStorage read is synchronous and fast
Identity Bootstrap: One-time cost on fresh login, prevents subsequent auth errors
Strategy Pattern: No runtime overhead - DI resolves strategy at component creation
Monitoring Query: New kpiDetailsForMonitoringAll fetches all KPIs - ensure pagination or filtering on large datasets

Test Coverage Impact

Metric	Before	After	Change
Spec Files	37+	~28	-9 files
Integration Tests	1 suite	0	-1 suite

Recommendation: Verify that E2E tests (Playwright) provide adequate coverage for the removed integration tests.

Prioritized Recommendations

Before Merge (Blocking)

Resolve commented-out test code in:
- auth-logout-integration.service.spec.ts (line 235)
- self-assessment.component.spec.ts (line 314)
Document test deletions - Add PR description explaining why integration tests and spec files were removed

After Merge (Non-blocking)

Consider adding unit tests for AuthLink class
Verify getAllKPIsForMonitoring() still needs manual authService.getAuthContext() or if AuthLink handles it
Monitor error rates for "not authorized" errors post-deployment
