QA report — Custom Worksheets Graphical Statistics Stage 1

Automated checks run against the Stage 1 module:

• JavaScript syntax check: PASS
• Y3 bar-chart pool: 68 generated instances, 17 stable subtypes: PASS
• Y4 bar-chart pool: 116 generated instances, 29 stable subtypes: PASS
• Y4 time-graph pool: 44 generated instances, 11 stable subtypes: PASS
• Y5 line-graph pool: 80 generated instances, 20 stable subtypes: PASS
• Y6 line-graph pool: 104 generated instances, 26 stable subtypes: PASS
• Prompt/answer/visual metadata present: PASS
• Stable keys unique within each pool: PASS
• Series lengths aligned to category/x arrays: PASS
• y-axis bounds valid: PASS
• deterministic mixed text + graph generation: PASS
• same-subtype graph replacement: PASS
• multi-page visual preview packing: PASS
• multi-page PDF document creation: PASS

Regression boundary:

• If a sheet contains no visual questions, generation delegates to the existing generator and PDF/preview layout.
• The new scripts load only on /tools/99-club/custom/.
• Public /tools/99-club/ is untouched by this patch.

Known Stage 1 limitation: This is the first integration build and should be browser-tested in the actual site before promoting the hidden Custom Worksheets module publicly.
