What this list does and does not cover
85 people who took the stand, reconciled against the day accounts on August 24, 2026. Witnesses are named in court and in reporting far more reliably than exhibits or searches, so this is close to complete for the sittings covered -- but it holds only those who have testified, and the defense case and the Commonwealth's rebuttal were still running when it was compiled. Four names are spelled differently by different outlets; see the discrepancy index.
