Roadmap: v17.6+ Post-v17.5 Enhancements

Created: 2026-01-25 Status: Complete (Audit/Recheck Finished) Dependencies: v17.5 (Performance Tracking & Circuit Breaker)

Overview

This roadmap covers follow-up work after the v17.5+ implementation. These enhancements build on the performance tracking, circuit breaker, and load testing infrastructure to improve resilience, observability, and data quality.

Estimated Total Time: 8-12 hours


Phase 1: Load Testing Baseline Establishment

Priority: HIGH Estimated Time: 2-3 hours Dependencies: v17.5 load testing infrastructure

Objective

Establish baseline performance metrics by running comprehensive load tests against the current implementation. These baselines will be used for:

  • Regression detection in future releases
  • Capacity planning
  • SLA/SLO definition
  • Infrastructure optimization decisions

Tasks

Task 1.1: Run Smoke Test and Document Results

Time: 30 minutes

# Run smoke test
npm run test:load:smoke

# Document results in baseline report

Expected Metrics:

  • Request success rate: >99%
  • p95 latency: <1000ms
  • p99 latency: <2000ms
  • No errors or timeouts

Deliverable: docs/testing/baseline-metrics.md (initial section)

Task 1.2: Run Search API Load Test

Time: 1 hour

# Run realistic load test
npm run test:load

# Analyze results
k6 run --out json=results/search-api-baseline.json tests/load/search-api.k6.js

Test Scenarios:

  1. Keyword search (no filters)
  2. Category filtered search
  3. Geo-proximity search
  4. Combined filters
  5. Crisis query handling

Expected Metrics:

  • Throughput: 50+ req/sec sustained
  • p95 latency: <500ms
  • p99 latency: <1000ms
  • Error rate: <5%

Deliverable: Baseline metrics documented with timestamps and environment details

Task 1.3: Run Sustained Load Test

Time: 45 minutes

# Run 30-minute sustained load test
npm run test:load:sustained

Observe:

  • Memory usage over time (no leaks)
  • CPU usage stability
  • Database connection pool behavior
  • Circuit breaker state (should remain CLOSED)
  • IndexedDB performance degradation (if any)

Expected Metrics:

  • Stable latency throughout duration
  • No memory leaks (flat memory usage)
  • Consistent error rate (<5%)

Deliverable: Long-duration stability report

Task 1.4: Run Spike Test

Time: 30 minutes

# Run spike test
npm run test:load:spike

Observe:

  • Recovery time after spike
  • Circuit breaker behavior under stress
  • Error rate during spike
  • Graceful degradation to JSON fallback

Expected Metrics:

  • Circuit breaker opens during spike (expected)
  • Recovers within 30s after spike ends
  • No permanent degradation after recovery

Deliverable: Spike test report with circuit breaker telemetry

Task 1.5: Create Baseline Documentation

Time: 30 minutes

File: docs/testing/baseline-metrics.md

Structure:

- Error rate increase: >2%
- Circuit breaker false-opens: >0

## Next Review: 2026-02-25

Deliverable: Complete baseline documentation


Phase 2: Integration Tests for Circuit Breaker

Priority: MEDIUM Estimated Time: 3-4 hours Dependencies: v17.5 circuit breaker implementation

Objective

Add integration tests that simulate real database failures to validate circuit breaker behavior in production-like scenarios. Current tests use mocked functions; integration tests will use test databases or simulated network failures.

Tasks

Task 2.1: Create Test Infrastructure

Time: 1.5 hours

File: tests/integration/circuit-breaker-db.test.ts

Setup:

  • Use Supabase local development setup (if available)
  • OR use test database with controllable downtime
  • OR use network interception (Playwright/MSW at network level)

Test Utilities:

// tests/integration/utils/db-simulator.ts

/**
 * Simulates database failures for integration testing
 */
export class DatabaseSimulator {
  private shouldFail = false
  private failureCount = 0

  /**
   * Make next N database calls fail
   */
  simulateFailure(count: number): void {
    this.shouldFail = true
    this.failureCount = count
  }

  /**
   * Restore normal database behavior
   */
  restore(): void {
    this.shouldFail = false
    this.failureCount = 0
  }

  /**
   * Check if should fail this call
   */
  shouldFailThisCall(): boolean {
    if (!this.shouldFail || this.failureCount <= 0) {
      return false
    }
    this.failureCount--
    return true
  }
}

Deliverable: Test infrastructure for simulating failures

Task 2.2: Write Integration Tests

Time: 1.5 hours

Test Cases:

  1. Circuit Opens on Repeated Failures
it('should open circuit after threshold failures', async () => {
  // Simulate 3 database failures (threshold)
  dbSimulator.simulateFailure(3)

  // Make requests that will fail
  await searchServices(...) // Fail 1
  await searchServices(...) // Fail 2
  await searchServices(...) // Fail 3

  // Circuit should be open
  const stats = getSupabaseBreakerStats()
  expect(stats.state).toBe('OPEN')

  // Next request should fast-fail (<1ms)
  const start = performance.now()
  await searchServices(...)
  const duration = performance.now() - start
  expect(duration).toBeLessThan(1)
})
  1. Automatic Recovery via HALF_OPEN
it('should recover automatically after timeout', async () => {
  // Open circuit
  dbSimulator.simulateFailure(3)
  // ... make failing requests ...

  // Wait for timeout (30s default)
  await new Promise(resolve => setTimeout(resolve, 31000))

  // Restore database
  dbSimulator.restore()

  // Next request should attempt HALF_OPEN
  const stats1 = getSupabaseBreakerStats()
  expect(stats1.state).toBe('HALF_OPEN')

  // Successful request should close circuit
  await searchServices(...)

  const stats2 = getSupabaseBreakerStats()
  expect(stats2.state).toBe('CLOSED')
})
  1. Fallback to JSON on Circuit Open
it("should fallback to JSON when circuit is open", async () => {
  // Open circuit
  dbSimulator.simulateFailure(3)
  // ... make failing requests ...

  // Search should still work via JSON fallback
  const results = await searchServices({ query: "food bank" })
  expect(results).toBeTruthy()
  expect(results.length).toBeGreaterThan(0)

  // Verify data came from JSON, not database
  // (check logs or metadata)
})
  1. Circuit Remains Open on Continued Failures
it('should remain open if recovery fails', async () => {
  // Open circuit
  dbSimulator.simulateFailure(10)
  // ... open circuit ...

  // Wait for HALF_OPEN
  await new Promise(resolve => setTimeout(resolve, 31000))

  // Next request fails (database still down)
  await searchServices(...)

  // Circuit should reopen
  const stats = getSupabaseBreakerStats()
  expect(stats.state).toBe('OPEN')
})
  1. Analytics Graceful Degradation
it('should skip analytics when circuit is open', async () => {
  // Open circuit
  dbSimulator.simulateFailure(3)
  // ... open circuit ...

  // Analytics call should not throw
  expect(async () => {
    await trackEvent({...})
  }).not.toThrow()

  // Analytics should be queued or dropped (logged)
  // Verify via logs
})
  1. Service Management Falls Back
it("should return null for service lookups when circuit open", async () => {
  // Open circuit
  dbSimulator.simulateFailure(3)
  // ... open circuit ...

  // Service lookup should return null (graceful)
  const service = await getServiceById("some-id")
  expect(service).toBeNull()
})
  1. Offline Sync Respects Circuit State
it("should skip sync when circuit is open", async () => {
  // Open circuit
  dbSimulator.simulateFailure(3)
  // ... open circuit ...

  // Sync should skip immediately
  const result = await syncServices()
  expect(result.status).toBe("error")
  expect(result.error).toContain("Circuit breaker open")
})
  1. Circuit Telemetry Logs State Transitions
it('should log all state transitions', async () => {
  const logs: string[] = []
  // Mock logger to capture logs

  // CLOSED → OPEN
  dbSimulator.simulateFailure(3)
  // ... open circuit ...
  expect(logs).toContain('CLOSED → OPEN')

  // OPEN → HALF_OPEN
  await new Promise(resolve => setTimeout(resolve, 31000))
  await searchServices(...)
  expect(logs).toContain('OPEN → HALF_OPEN')

  // HALF_OPEN → CLOSED
  dbSimulator.restore()
  await searchServices(...)
  expect(logs).toContain('HALF_OPEN → CLOSED')
})

Phase 3: French Translation Workflow

Priority: LOW (Manual Work Required) Estimated Time: 2-3 hours (automation) + User Time (translation) Dependencies: None

Objective

Create helper tools to streamline the manual French translation workflow. The workflow still requires external translation handling and human review, but we can make it more efficient.

Tasks

Task 3.1: Create Translation Helper Script

Time: 1.5 hours

  prompt += `- Preserve meaning, no new claims\n`
  prompt += `- Use natural, conversational Canadian French\n`
  prompt += `- Keep technical terms appropriate (e.g., "email" → "courriel")\n\n`
  prompt += `**Format:** For each service, provide the French translation.\n\n`
  prompt += `---\n\n`

  batch.services.forEach((service, idx) => {

Deliverable: Translation helper script with CLI

Task 3.2: Update Workflow Documentation

Time: 30 minutes

File: docs/workflows/french-translation-workflow.md (update)

Add Section:

## Using the Translation Helper

### Step 1: Generate Prompts

For each batch, generate a translation prompt:

```bash
npm run translate:prompt docs/audits/v17-5/ai-results/access-script-fr/input/batch-001.json
```

This creates a markdown file at: docs/audits/v17-5/ai-results/access-script-fr/prompts/batch-001-prompt.md

Step 2: Translate Using Your Preferred AI Service

  1. Open the prompt file
  2. Copy the entire content
  3. Paste into Claude, ChatGPT, or DeepL
  4. Copy the AI's response
  5. Save to a text file: batch-001-response.txt

Step 3: Parse and Validate

Parse the AI response back into JSON format:

npm run translate:parse \
  docs/audits/v17-5/ai-results/access-script-fr/input/batch-001.json \
  batch-001-response.txt

This will:

  • Parse the AI response
  • Validate translations
  • Save output to output/batch-001.json

Step 4: Review and Correct

If validation fails, manually review and correct the output JSON file.

Then validate again:

npm run translate:validate docs/audits/v17-5/ai-results/access-script-fr/output/batch-001.json

Step 5: Merge All Batches

Once all batches are validated:

npm run merge-ai-enrichment -- \
  docs/audits/v17-5/ai-results/access-script-fr/output/batch-*.json

Step 6: Rebuild

npm run build  # Regenerates embeddings
**Deliverable:** Updated workflow documentation

#### Task 3.3: Add Tests for Helper Script

**Time:** 1 hour

**File:** `tests/unit/batch-translate-helper.test.ts`

**Test Cases:**
- Generate prompt with correct format
- Parse AI response correctly
- Validate complete translations
- Detect missing translations
- Warn on potential English words in French
- Handle malformed AI responses

**Deliverable:** Test suite for translation helper

---

## Phase 4: Authorization Protection Discussion

**Priority:** MEDIUM (Requires Decision)
**Estimated Time:** 1-2 hours (investigation) + Implementation TBD
**Dependencies:** v17.5 circuit breaker

### Objective

Investigate and decide whether to add circuit breaker protection to authorization checks in `lib/auth/authorization.ts`. This is a security vs. resilience trade-off that requires careful consideration.

### Tasks

#### Task 4.1: Security Analysis

**Time:** 30 minutes

**Questions to Answer:**

1. **What happens if authorization checks fail-open?**
   - Could users access resources they shouldn't?
   - Could service owners edit services they don't own?
   - Could non-admins access admin functions?

2. **What happens if authorization checks fail-closed?**
   - Users cannot access their own resources during outage
   - Service owners cannot manage their listings
   - All authenticated actions fail

3. **Current fallback behavior:**
   - Review `assertServiceOwnership()` - throws on failure
   - Review `assertOrganizationMembership()` - throws on failure
   - Review `assertPermission()` - throws on failure
   - All use `createServerClient()` which requires database

**Deliverable:** Security analysis document

#### Task 4.2: Examine Usage Patterns

**Time:** 30 minutes

**Analyze All Call Sites:**

```bash
# Find all authorization function calls
grep -r "assertServiceOwnership\|assertOrganizationMembership\|assertPermission" app/ lib/

Categorize by Risk:

  • High Risk: Ownership transfers, deletions, role changes
  • Medium Risk: Service edits, member invites
  • Low Risk: Read operations, analytics viewing

Deliverable: Usage pattern analysis with risk categorization

Task 4.3: Propose Solution Options

Time: 30 minutes

Option 1: Fail-Closed (Current Behavior)

  • ✅ Secure by default
  • ❌ Total service outage during DB failure
  • ❌ No graceful degradation

Option 2: Fail-Open with Audit Logging

  • ✅ Service remains available
  • ⚠️ Security risk during outage
  • ✅ Audit logs for review after recovery
  • Implementation: Skip authorization checks when circuit open, log all actions

Option 3: Cached Authorization

  • ✅ Secure
  • ✅ Resilient (if cache hit)
  • ⚠️ Complex invalidation logic
  • Implementation: Cache membership/ownership in Redis/memory for 5-10 minutes

Option 4: Tiered Approach

  • ✅ Balanced security and resilience
  • ✅ Low-risk operations remain available
  • ❌ High-risk operations fail-closed
  • Implementation:
    export async function assertServiceOwnership(
      supabase: SupabaseClient,
      userId: string,
      serviceId: string,
      allowedRoles: Role[] = [],
      riskLevel: 'high' | 'medium' | 'low' = 'medium'
    ): Promise<void> {
      try {
        const { data, error } = await withCircuitBreaker(
          async () => supabase.from('organization_members')...
        )
        // ... existing logic ...
      } catch (error) {
        if (error instanceof CircuitOpenError) {
          if (riskLevel === 'high') {
            // Fail-closed for high-risk operations
            throw new AuthorizationError('Service temporarily unavailable')
          } else {
            // Allow with audit log for low/medium risk
            logger.warn('Authorization bypassed: Circuit breaker open', {
              userId,
              serviceId,
              riskLevel,
            })
            return // Allow
          }
        }
        throw error
      }
    }
    

Option 5: Read-Only Mode

  • ✅ Secure (no writes)
  • ✅ Users can still browse/search
  • ⚠️ Cannot make changes during outage
  • Implementation: Allow read operations, fail-closed for write operations

Deliverable: Solution options with pros/cons

Task 4.4: Decision Document

  1. Implement and test helper script
  2. Update documentation
  3. Run on one batch as proof-of-concept
  4. User completes remaining batches at their pace

Phase 4: Authorization (If Approved)

  1. Create ADR and get stakeholder approval
  2. Implement chosen strategy in feature branch
  3. Comprehensive security testing
  4. Gradual rollout: staging → 10% → 50% → 100%
  5. Monitor audit logs closely for 2 weeks
  6. Roll back if any security concerns detected

Future Considerations

Performance Monitoring Dashboard

  • Real-time circuit breaker status visualization
  • Performance metrics graphs (p50/p95/p99 over time)
  • Alerting on threshold violations
  • Integration with Axiom/Sentry for production

Automated Load Testing in CI

  • Scheduled weekly load tests
  • Automatic baseline comparison
  • Regression alerts on pull requests

Enhanced Circuit Breaker

  • Per-operation circuit breakers (separate for auth, analytics, services)
  • Dynamic threshold adjustment based on historical failure rates
  • Predictive circuit opening based on latency trends

Multi-Region Resilience

  • Database replica failover
  • Cross-region circuit breaker coordination
  • Geo-distributed load balancing

Notes

  • Load tests should be run during off-peak hours to avoid impacting real users
  • Integration tests with 30s+ timeouts should be clearly marked in CI
  • Authorization changes require security team approval before implementation
  • Translation workflow is inherently manual due to quality requirements
