99 Club Studio v1.22.2 patch instructions

Baseline

Apply this patch directly over v1.21.3.

Do not apply v1.22 or v1.22.1 first. Those were internal/withdrawn Angles QA builds and are superseded by this package.

What this patch contains

  • Angles & Turns Stage 1, visually reliability-reviewed: 104 active subtypes / 416 deterministic entries.
  • Angles visual-polish pass: larger protected figures, clearer turn/label layouts, improved line/point/triangle spacing and rebuilt 1°/5°/10° dual-scale protractor.
  • Pie Chart variety expansion: 37 subtypes × 16 deterministic variants = 592 pool entries, with structural/chart-layout variation and anti-repetition selection.
  • Explicit estimation/measurement marking, working/explanation frames and teacher rubrics.
  • Conventional vertical y-axis titles for bar/time/line graphs.

Deployment

  1. Apply the ZIP contents at repository root, preserving paths.
  2. Deploy normally.
  3. Hard-refresh /tools/99-club/custom/ after deployment because Custom asset cache versions changed.
  4. Check one question from each Angles family, a protractor question, several Pie Chart questions from the same family, and pupil/answer PDF export.

The public 99 Club page and public Help remain unchanged.
