CYCLE 4 Stress Plan v0.1

Date: 2026-04-19Status: startedFocus: D03 (review), robustness audit, final cycle decision.

Goals

1. Rerun D03 with a revised operating criterion to recover condom/degenerative coexistence.2. Perform sensitivity stress tests on thresholds (Phi, Loss_U, ambiguous band).3. Consolidate reproducibility audit on D02/A01/D03.

Work packages

WP1 - D03 Revision

• Redefine "ambiguous" class with non-adaptive pre-registered rule.- Compare at least 2 robust classification schemes.- Output: results_D03_cycle4_v0_1.md.

WP2 - Stress/Ablation

• Stress on input noise and distributional shift.- Ablation on proxy components (jaccard, soft_overlap, loss_u).- Output: stress_ablation_cycle4_v0_1.md.

WP3 - Final Audit

• Replay of runs with declared seeds.- Check log consistency and aggregate metrics.- Output: CYCLE_4_REPORT.md.

Cycle 4 exit criterion

• validated if global protocol criteria met;- revise if partial but not robust evidence;- reject if falsified criteria.
