Get Current Round

Returns the header of the number-entry screen for a room: the open round with its close time and seed commitment, the lucky number and the last two results. Call it after the player picks a room and again when a round closes.

Rules

Lotto only: the route is under /g/lotto, so system maintenance and Lotto's own maintenance window both answer 503 99915.

POST with a JSON body even though it is a read.

Body key is roomId (lower-case d), the room number from GET …/rooms.

Validation failures answer 400 99911 with the generic description "Bad request."; unlike the other LOTTO POST endpoints, the field is not named.

round is null when no round is open yet; poll again. Its roundId (lower-case d) is what tickets/create, my-bets, my-result and provably-fair take.

drawAt always equals closeAt: the draw happens as soon as betting closes.

lucky is null when the feature is off or no round has settled yet.

recentResults holds up to the 2 latest settled numbers, newest first, and is always an array ([] when none); it is filled even when the lucky feature is off.

The room must serve the session currency (99955).

LOTTO sends no round_started event: call this again after SSE round_settled or once closeAt passes to get the next round.

Flow

Accept LOTTO only; validate roomId; check the session game.

Check the game is available; load the room (must exist and be active) and check it serves the session currency.

Add the open round for room + currency, or null.

Add the last 2 settled numbers, and the lucky number when the feature is on.
