audit-render

name: audit-render description: Audit the browser rendering pipeline for scissor/clipping bypass bugs. Use when touching browser-buffer.ts, canvas-painter.ts, or adding new visual features.

Audit the rendering pipeline to ensure every canvas-level drawing path respects the scissor (overflow:hidden) system.

1. Spawn the render-pipeline-audit agent as a background agent.

2. Wait for it to complete.

3. Present findings:

   • Must Fix: Any buffer→painter channel missing scissor capture or painter clipping
   • Should Fix: Channels with bounds-checking but no scissor clipping (low risk)
   • OK: Channels that are safe (cell-grid bounded or fully scissor-aware)

4. If issues are found, suggest the fix pattern:

   • Add clipRect? field to the data type
   • Capture scissorStack[top] at write time, skip if fully outside
   • Apply ctx.save() / ctx.rect(clipRect) / ctx.clip() / ctx.restore() in the painter
   • Add tests for: capture, skip, paint-clip, no-clip-when-absent
