Variable: RELEVANCE_FLOOR_MIN

const RELEVANCE_FLOOR_MIN: 0.125 = 0.125;

Defined in: src/batteries/context/thrift/relevance.ts:44

The relevance floor's lower bound — the minimum fraction of the current query's content words a turn must share to be kept, used when the window is nearly empty (permissive: keep almost anything that shares ANY real overlap).

Remarks

CALIBRATED against a relevance oracle over a 94-turn stress corpus, triple-confirmed across three model families acting as independent judges (gpt-5.5, gemini-3.5-flash, claude-haiku-4.5): the F1-optimal floor (best balance of precision and recall when window budget is abundant) landed at 0.125 for gpt-5.5 and claude-haiku-4.5 exactly, and 0.111 for gemini-3.5-flash — 0.125 was chosen as the shared default (a hair stricter than gemini's number, i.e. slightly more permissive than not, which the calibration run characterized as "slightly permissive" rather than under-inclusive — the safer direction to err when the window has room to spare).
