Response drift: smarkets — `markets[].inplay_enabled` not in interface, not accessed

What Our Normalizer Expects

The SmarketsRawMarket TypeScript interface does not declare inplay_enabled. The smarkets normalizer does not access this field when normalizing markets.

What The Live API Returns

The live markets endpoint returns:

markets[].inplay_enabled: boolean

This flag indicates whether the market accepts in-play (live) betting after the event has started.

Impact

• Normalized smarkets markets carry no in-play availability signal
• Consumers cannot distinguish pre-match-only markets from in-play markets
• Attempting to place in-play bets on markets where inplay_enabled: false would fail at the venue with no prior warning from the unified feed

Suggested Fix

1. Add inplay_enabled?: boolean to the SmarketsRawMarket interface
2. Surface it on the normalized UnifiedMarket (e.g., as isInplayEnabled in sourceMetadata or as a dedicated field if the unified schema supports it)
