ShadowDecision already carries the V3.4 5-factor breakdown (base_leverage, dc_lev_mult, regime_size_mult, market_ob_mult, esof_size_mult), but the journal row and CH DDL dropped it — so a DARK soak would record decisions WITHOUT the factor decomposition that V3.4 exists to expose. Thread it through: - 22_violet_decisions.sql: 5 additive Nullable(Float64) breakdown columns. NULL on the legacy base-only path; populated once the launcher feeds live factor planes. Note added: on a pre-existing table use ALTER ... ADD COLUMN instead of the CREATE IF NOT EXISTS (no live table yet — VIOLET is DARK, never soaked). - shadow_journal.py: DecisionRow gains the 5 Optional[float] fields (ge=0.0, finite-guarded); journal() populates them via getattr(..., None) so the base-only path and duck-typed reject tests stay NULL/rejected rather than raising on attribute access. - test_violet_shadow_journal.py: breakdown round-trips on the full path; NULL on base-only; a negative multiplier is rejected at the row guard. The existing DecisionRow-fields == DDL-columns parity test still holds with the new columns. violet-only; no shared-file edits; no soak. 29 violet tests green (7 journal + 22 engine/DDL-apply).
