VIOLET_PART_SPEC_OA_TODO.md carves the self-contained pending items from the VIOLET plan so a
separate agent can work without colliding with in-flight files:
1. Parity-pin tests for sizing.py's hand-replicated arithmetic (regime/ob/strength/dc) vs the
real NDAlphaEngine methods — test-only.
2. Multi-exchange OB provider seam (VioletVenueOBProvider scaffold + interface + design note)
— the BingX/3rd-party swap point, NOT wired live.
3. Base-fraction sizing study (analysis script + report) — pure read-only analysis, no
behavior change.
Each task: exact affected (new-only) files, V-TYPES + DARK + never-touch-shared rules, required
tests + pass criteria. Includes an explicit COMMIT/BRANCH policy (own git worktree, or partial
commits with `git commit -- <paths>`) prompted by today's three shared-index collisions.
