# candidate_02 — Quantization deformation atlas

Assigned by Phase 4 (`research/candidate_ranking.md`). Core gaps: G01 (+G02, then G04/G05).

**First falsifier:** Qwen3-0.6B FP16 vs Q4 probe drift vs seed/dataset noise floor: 10 properties × 5 seeds × 2 datasets.

Status: assigned — prototyping starts after the mandatory substrate
(expH capture-cost frontier, expA/expD noise floors, map-cards v0).
Hypothesis will be registered in `hypothesis.md` before any run (charter §10).
