> V2 documentation parity slice — crankless BST matching, V2 API reference, place_order_v2 tutorial, and Quant Hub vault roles.

# Week of June 23, 2026

Documentation sync for the hardened V2 architecture (per `V2_DOCS_SYNC_SPEC`).

## Documentation

* **[Unified portfolio](../overview/unified-portfolio)** — added crankless BST matching flow, V1/V2 comparison table, and architecture diagrams.
* **[V2 API endpoints](../developers/api-v2)** — new narrative reference for `/api/v2/portfolio`, `/markets/orderbook`, `/leaderboard`, and `/referrals/validate`.
* **[Building on QuantDesk](../developers/building-on-quantdesk)** — new `place_order_v2` integrator tutorial with seat claims and side encoding.
* **[Copy trading](../social/copy-trading)** — documented Quant Hub vault leader roles and the 100bps slippage band.
* **[Order book](../trading/order-book)** — linked V2 BST depth to the orderbook API route.

## Polish (validation follow-up)

* **[Building on QuantDesk](../developers/building-on-quantdesk)** — added `initialize_portfolio` step before seat claim.
* **[Portfolio parsing](../developers/portfolio-parsing)** — complete 2,360-byte offset map with nested struct sizes.
* **[Order book](../trading/order-book)** — crankless BST matching section moved here from Overview for clearer IA.
* **[Unified portfolio](../overview/unified-portfolio)** — slimmed to portfolio focus; links to Trading for execution depth.
* **[V2 API endpoints](../developers/api-v2)** — softened internal table naming in portfolio route description.
