jgrusewski 938ea3f0cd docs: spec — IBKR consolidation (OPRA-backed XSP-VRP + UCITS multistrat routing)
One fused venue-consolidation spec, two bounded components, execution coded-but-suspended:

- Component A (centerpiece): a `vrp` sleeve rebuilt on REAL OPRA option data (XSP
  put-credit-spreads, 2013→). Databento OPRA.PILLAR verified empirically (XSP/SPX bars
  back to 2013-04-01). Put-call-parity forward + IV-inversion 20Δ strike + real-mark
  defined-risk P&L, frozen into an xsp_option_bars PIT table. Wired to forward engine +
  reconciliation gate + merged CVaR sizing + cockpit. Supersedes the parked flat-VIX
  synthetic spec (biased placeholder).
- Component B (thin): UCITS-legal execution routing for the existing multistrat — modeled
  track UNCHANGED (models US underlyings, long history); adds a US→UCITS instrument map +
  `--venue ucits` execute path. PRIIPs blocks US ETFs on a Dutch retail account.

Both exec legs ship SUSPENDED (C1/C2/C3 pattern) — neither XSP options nor UCITS-Euronext
can be paper-executed on the US-style DU9600528 account. Crypto stays structurally on Bybit
(perp edges; IBKR can't host). Marks 2026-07-11 synthetic-VRP spec SUPERSEDED.
