Triage outcome: not merge-ready.

Blocking factors:

• Merge conflicts (DIRTY/conflicting)
• Large multi-feature blast radius in one PR
• No active checks currently attached

Please split into smaller PRs (API, UI panels, theme/system changes), rebase on latest main, and rerun full quality gate.

Triage enforcement update from maintainers:\n\nStatus: not mergeable in current form.\n\nBlocking reasons:\n- PR is conflicting with main.\n- Large multi-feature scope (trading ops + backtesting + bridge panels) with high review surface.\n- Missing completed review/check cycle for this branch state.\n\nRequired path forward:\n1) Rebase and split into phased PRs by feature area.\n2) Add per-phase acceptance criteria and tests.\n3) Land incrementally behind guarded UI flags if needed.\n\nRecommendation: close and relaunch as phased implementation PRs.\n

Tracking replacement scope in #540. Recommend closing this PR in favor of the scoped implementation issue.
