Data: fleet-sessions-30d-2026-09-15 (complete census, 1,731 sessions) · thread ground truth computed by blast_radius.py against signatures/cassette-decision.json, itself a floor: sessions that never name the work slip through even here. 32 sessions carry list-rollup data only (their full exports failed); costs are provider billing rollups. Identifiers truncated, engineers pseudonymized, paths shortened to their last two segments; titles outside the thread and its look-alike matches are withheld, so match counts for searches beyond the preset ones are a floor.
