feat(m3): TS-token effectiveness check (T3.3) — change_rate=0.98/50 ≫ 0.5 target
- eval/ts_effectiveness.py: perturbation sensitivity (hard perturb vs light
InfoNCE positives) + must-see-TS overlap sanity.
- Measured on stage1_final.pt: 49/50 held-out answers change under strong
perturbation → proves the TS modality is actually consumed.
- Stage1 (frozen LLM) structurally emits some JSON/prose but cannot yet do
task-quality answers → deferred to M5 pure-LLM baseline comparison.
- Mark T3.3/T3.4 (M3 exit) done.
