VIOLET OA: partial spec PASS 9 — economics + observability completeness (OA backlog complete)

VIOLET_PART_SPEC_OA_TODO_PASS9.md — the final parallelizable pass, discharging VIOLET's binding V1
economics/observability inheritance. Six independent units extending contracts_v3 (Provenance/
EconomicsRow/DecisionDivergenceRow/SoakReadiness):
  43. Observability/economics contracts.
  44. DDL-first exactly-one-row-per-event economics sink (ReplacingMergeTree key, event_seq,
      wait_for_async_insert=1, reject-at-source) — the PINK duplicate-emission fix.
  45. Provenance + per-trade PnL feedback (capital = anchor + Σ trade-realized; never a balance
      snapshot — shared-account foreign-fill immunity).
  46. Factor-plane divergence monitor v2 (per-factor VIOLET-vs-BLUE abs_err, DDL-first).
  47. Soak-readiness aggregator (consolidate all reports → SoakReadiness GO/NO_GO).
  48. Soak-readiness @gate — GO iff parity≥thr ∧ latency ∧ determinism ∧ one-row ∧ isolation;
      EXPECTED NO_GO today by design (CRITICAL #1), the gate makes it machine-checked (not forced green).

DDL-first + row-set==DDL parity + reject-at-source discipline throughout; never writes a production
table (new dolphin_violet tables only); ch_writer.py not edited.

OA BACKLOG COMPLETE: PASS 1–9 (~48 independent contracts_v3-keyed units) cover the full
parallelizable DARK surface of V0→V6. Remaining work is non-parallelizable + Claude's: parity
root-cause, review of all passes, integration, E2E, VBT re-cert, real-key V4 smoke, live execution.
