Function: selectRelevantTurns()

function selectRelevantTurns<M, TC>(
  turns: readonly HistoryTurn<M, TC>[],
  queryText: string,
  options: SelectRelevantTurnsOptions,
): HistoryTurn<M, TC>[];

Defined in: src/batteries/context/thrift/relevance.ts:295

Select which turns to replay by RELEVANCE to the current query: always keep the most recent keepRecent turns, and among the OLDER turns keep any whose relevanceToQuery score against the query's content words clears a floor that scales with how much of the older-history budget is already spoken for (see scaledRelevanceFloor). Walks the ENTIRE history — there is no turn-count cap — so a turn from far in the past survives if it is genuinely relevant, which a recency-only policy (see selectNaiveTurns) can never do.
