=== ALERTS ===

🔴 HIGH PRIORITY:

  unvalidated-input [security] [blocking]
  ├─ Trend: +150% (2 → 5 occurrences)
  ├─ Affected: api-dev in compute-api, network-api
  └─ Action: Consider team training on input validation patterns

  missing-status-condition [correctness] [blocking]
  ├─ Trend: +100% (3 → 6 occurrences)
  ├─ Affected: api-dev across all services
  └─ Action: Review status condition checklist in api-dev runbook

🟡 WATCH:

  storage-init-race [correctness] [warning]
  ├─ Trend: new (0 → 3 occurrences)
  ├─ Affected: api-dev in compute-api
  └─ Action: Monitor; may indicate new pattern emerging

=== IMPROVEMENTS ===

✅ hardcoded-value
   ├─ Trend: -60% (5 → 2 occurrences)
   └─ Team is improving on avoiding hardcoded values

✅ import-ordering
   ├─ Trend: resolved (3 → 0 occurrences)
   └─ Convention now consistently followed

=== CROSS-SERVICE INSIGHTS ===

Services with most findings:
  1. compute-api:  15 findings (8 patterns)
  2. network-api:  10 findings (6 patterns)
  3. storage-api:   5 findings (4 patterns)

Pattern correlation:
  - missing-status-condition appears across ALL services
  - storage-init-race concentrated in compute-api (investigate)

=== RECOMMENDATIONS ===

1. Address unvalidated-input trend
   - Add validation examples to api-dev runbook
   - Consider pre-commit validation hook

2. Investigate storage-init-race
   - New pattern in compute-api
   - Check if network-api/storage-api have similar code

3. Celebrate improvements
   - hardcoded-value and import-ordering trending down
   - Team learning is working

=== ACTIONABLE ALERTS ===

IMMEDIATE ACTION REQUIRED:

1. unvalidated-input is increasing rapidly
   Severity: blocking | Trend: +150%

   Recommended actions:
   - Review recent PRs for validation patterns
   - Update api-dev runbook with validation checklist
   - Consider adding validation to PR template

2. missing-status-condition spreading across services
   Severity: blocking | Trend: +100%

   Recommended actions:
   - Add status condition check to code-reviewer priority list
   - Create shared utility for status condition updates
   - Add to api-dev workflow checklist

MONITOR:

3. storage-init-race is a new pattern
   Severity: warning | Occurrences: 3

   Recommended actions:
   - Document pattern in api-dev runbook
   - Check other services for similar code
   - Consider adding to validation scripts
