1. FIRC0002 L2–L10 results (run 7): rebuilt panel, core + extended + event-study + survivorship results, construct-validity rows, 33 regenerated tables with notes, 442 macros, 17 figures

   …

   AR-FIRC0002-1: trigger (a) not fired (wins. EW spread +3.9 pp NW t 2.06 / plain 1.81, CI covers 0; wins. FM +1.88 pp/SD t 2.41);
   trigger (b) not fired on the literal criterion (large-vs-small gradient persists in sorts, contrast t 1.83 firm / 1.55 two-way,
   wild p 0.22) but the largest-1,000 1-y CDA t is 3.02 (IWV model) vs 1.12 beta-only / 1.21 market-adjusted / 0.51 FF6;
   trigger (c') not fired (size-tercile attrition; AI-quintile attrition = X1).
