Spec drift: smarkets — new cftc object field on events, markets, and contracts responses

[realfishsam]

Summary

Smarkets added a new cftc object field to event, market, and contract response schemas. This field contains CFTC-specific metadata (regulatory identifiers, contract specifications). The field is not present in core/specs/smarkets.yaml.

Impact

MEDIUM — the field is additive (no breakage), but it's undocumented in our spec and unavailable via callApi() typing. PMXT cannot surface CFTC regulatory data for Smarkets markets.

Details

• New field: cftc (object) on Event, Market, and Contract schemas
• Contents include: CFTC contract designation, designated contract market (DCM) identifier, and related regulatory metadata
• Spec file: core/specs/smarkets.yaml
• Related to Spec drift: kalshi — outcome_side/book_side replacing direction field (May 28 deadline) #514 (jurisdiction CFTC enum) — these are companion changes

Required Fix

Add the cftc field (as an optional object) to the Event, Market, and Contract schemas in core/specs/smarkets.yaml. Document its sub-fields based on the live API response shape.
