Status: Planned  
Track: `functional`  
Lineage role: `canonical`  
Previous state: `012-platform-convergence-c3`

This pack defines a functional interoperability layer on top of the C3 convergence baseline.

Primary intent:

*   make TraderX an FDC3 2.2-capable application that can exchange ticker context with desktop ecosystem apps,
*   support intent-driven ticket launch workflows (trade and order ticket prefilled from ticker context),
*   preserve existing TraderX trade/order/position behavior when FDC3 is unavailable,
*   provide deterministic tests that demonstrate FDC3 behavior against mocked and real demo-agent environments.

Core artifacts:

*   `spec.md`
*   `requirements/functional-delta.md`
*   `requirements/nonfunctional-delta.md`
*   `research.md`
*   `data-model.md`
*   `quickstart.md`
*   `contracts/contract-delta.md`
*   `system/architecture.model.json`
*   `system/architecture.md`
*   `system/runtime-topology.md`
*   `generation/generation-hook.md`
*   `tests/smoke/README.md`

Target runtime behavior:

*   Standard FDC3 context exchange (`fdc3.instrument`) between TraderX and external apps.
*   Standard intent handling (`ViewOrders`) and outbound intent raising (`ViewChart`, `ViewQuote`).
*   Custom intent handling for prefilled ticket launch (`TraderX.CreateTradeTicket`, `TraderX.CreateOrderTicket`).
*   Two-tab Sail demo profile with ticket-launch controls on tab `One` and news on tab `Two`.
*   Documented workaround debt for current Sail callback reliability and non-CDM symbology normalization.

Blotters default to **All tickers**. Use each blotter's **Filter on selected ticker** control to follow shared FDC3 instrument selection locally. See the [context contract](https://deploy-preview-472--lucky-concha-f3599f.netlify.app/specs/fdc3-intent-interoperability/contracts/contract-delta.md) and [acceptance scenarios](https://deploy-preview-472--lucky-concha-f3599f.netlify.app/specs/fdc3-intent-interoperability/spec.md) for account, empty-context and live-event semantics.
