Advanced Viz Report

Summary

• Added PosteriorPlot and SequentialBoundaryChart as lazy-loaded Recharts chunks in results flows.
• Added BayesianSection and wired the sequential chart into SequentialDesignSection.
• Added 8 new tests:
  • PosteriorPlot.test.tsx: 3
  • SequentialBoundaryChart.test.tsx: 3
  • a11y-bayesian-sequential.test.tsx: 2

Bundle Sizes

• Main JS: index-CMOwwYOH.js - 422.56 kB raw, 121.81 kB gzip
• Posterior chunk: PosteriorPlot-HSvvBNYq.js - 15.86 kB raw, 5.80 kB gzip
• Sequential chunk: SequentialBoundaryChart-D-70Cle9.js - 2.08 kB raw, 0.91 kB gzip
• Existing Recharts support chunks still split out:
  • CartesianChart-p8mC2DmH.js - 353.03 kB raw, 105.43 kB gzip
  • LineChart-L_foBXTA.js - 4.62 kB raw, 1.94 kB gzip

Verification

• python scripts\generate_frontend_api_types.py --check -> pass
• npm.cmd run test:unit -- src/components/PosteriorPlot.test.tsx src/components/SequentialBoundaryChart.test.tsx src/test/a11y-bayesian-sequential.test.tsx -> pass
• npm.cmd run test:unit -> fails on pre-existing src/i18n.test.tsx because src/i18n/index.ts does not expose an i18next instance with changeLanguage
• npm.cmd run build -> pass
• scripts\verify_all.cmd --with-e2e -> blocked before frontend verification by pre-existing backend/runtime issues:
  • default DB path: sqlite3.OperationalError: no such column: key_id
  • fresh temp DB path: TypeError: register_http_runtime() got an unexpected keyword argument 'repository'

Chart Snapshots

• Posterior plot:
  • Smooth posterior bell curve with a light filled area under the full density.
  • Darker shaded band across the credibility interval centered around the posterior mean.
  • Optional dashed prior line when prior inputs are supplied.
• Sequential boundary chart:
  • Two mirrored red boundary curves descending from high early-look z thresholds toward the final look.
  • Gray dashed reference lines at z = 1.96 and z = -1.96.
  • Optional vertical dashed marker for the current look.

Notes

• Full git status --short cannot be empty after this task because the repo already had many unrelated modified and untracked files before implementation.
