MS-2 of multi-step composition. Extends the derivation model so a chain mixes text-quantity operands and COMPARATIVE-scalar operands (twice->x2, 'N times'->xN, half->x0.5), self-verifying the whole chain with completeness over body+question and question-target matching. - model.py: Step gains comparative flag. - comparatives.py: ComparativeScalar gains number_token (the '<N> times' number, so completeness counts the consumed body quantity); comparative_step(cs) bridges a scalar into a Step (operand grounded by cue, not a text value token). - verify.py: self_verifies exempts comparative operands from value-grounding (clause 1) — they are cue-grounded (clause 2); completeness (Counter) counts a digit comparative's number_token as consuming the body quantity. Adds target_units to select_self_verified: a chain whose answer_unit isn't the asked unit is dropped (question-target match; empty target_units imposes no constraint). Proves the multi-step shapes from the gold structures: 0024 (text sum then 'three times' scale -> 438), 0033 father-chain (digit-comparative '7 times' + fixed 'half' + text add -> 47). Full 0033 DAG (quantity reuse + the question's 25) deferred. 25 MS-2 tests; full derivation surface 69/69 (3a/3b/comparatives/ms1/ms2); ruff clean; smoke 67. Not wired into serving (model ready for MS-3 target-guided search).
