Write and validate test coverage

Execute integration tests for multi-team deliverables and handoff flows

Verifying that frontend, backend, and infrastructure pieces actually work together in realistic scenarios before handing off to production ops.

• · feature from multiple teams (frontend, backend, infrastructure)
• · integration test specs

• · integration test report
• · failure analysis
• · handoff verification

• · pytest
• · playwright
• · curl
• · container orchestration

• · all components deployed to staging
• · test environment mirrors production

• · timing flake if async not awaited
• · data isolation broken if shared test DB

• · end-to-end flow verification
• · async handling
• · data cleanup between tests
• · environment parity check
• · failure diagnostics (logs, network traces)
