# Pre/Post Parity Report (Table/Chart/Filter/Interaction/Matrix)

Last updated: 2026-02-11

## Scope

Routes: `/wip-overview`, `/wip-detail`, `/hold-overview`, `/hold-detail`, `/hold-history`, `/resource`, `/resource-history`, `/qc-gate`, `/job-query`, `/excel-query`, `/query-tool`, `/tmtt-defect`.

## Method

- Pre-migration baseline:
  - `baseline_interaction_evidence.json`
  - `baseline_route_query_contracts.json`
  - `baseline_api_payload_contracts.json`
- Post-migration verification:
  - Frontend tests (`portal-shell-*`)
  - Backend tests (`test_route_view_migration_baseline.py`, `test_cutover_gates.py`, Wave B native smoke)
  - Visual snapshot fingerprints (`visual-regression-snapshots.json`)

## Page-by-Page Outcome

## Summary
