Notes	MMLU-collapse hypothesis FALSIFIED: dropping MMLU-Pi from FAIL bucket does not protect MMLU

Lineage

Continues the capability-vectors sweep. Phase 1 best was v2 (HA20 8/20, MMLU collapse 58→2). Phase 2 explores multi-token / hard-pairs / counterfactual / agent-only / activation-steering recipes.

See https://github.com/AlexWortega/capability-vectors for repo + per-experiment README, and phase2/results/all_variants.csv for the live results table.
