  "description": "PeerSympathy salvage variant: enter peers at peer's reaction_close on T (same trading day as the leader's print) instead of T+1 next_open. Hypothesis: peers move in the SAME intraday session as the leader (NVDA prints BMO -> AVGO/AMD rally same day's market hours), not on T+1 gap which already absorbed the news overnight. Filing-time bucket allow-list restricts to BMO + regular_hours leader prints; AMC filings are excluded because their reaction_date = T+1 means peer's reaction_close on T+1 is already ~20 trading hours after the news, defeating the same-session sympathy thesis. All other parameters identical to v1 baseline.",
