+## POST-PASS — two findings from another session, handled differently
+
+**1. Ashcroft is not an attacker, and the cut is three. APPLIED in v0.9.** Reading the two
+narrated fights showed Dominic attacking at `vs 1`, four times. Confirmed against the sheet
+rather than the log: `weapons: []`, and his only combat skill is Firearm (Pistol) 43 with
+nothing to fire. So the four-player cut fights with Renshaw and Bhattacharya on compact
+pistols and Braithwaite on a knife — **a quarter of the party out of any fight.**
+
+A defect I introduced. *"He carries no weapon, and the GM must not fix it"* was written as
+characterisation and never checked against a fight. The fix is to **say it, not repair it**:
+his player is told before the game that Dodge, First Aid, Insight and the anchor are his
+set-piece, the scaling note states the three-attacker arithmetic, and EXPOSURE names it as
+part of why violence at four players is party-ending. Arming him would have cost the
+character for a problem that was really a briefing failure.
+
+**2. The bimodality has a mechanism — VERIFIED, deliberately NOT published.** Both sides
+disable at half max HP, so every disable thins the return fire and makes the next likelier;
+nothing pulls the fight back toward the middle once it tips. First blood is a true coin in
+the cut and worth **43 points of wipe rate** (49.7% / 50.3% at mean round 1.7 → 23.1% against
+66.5% wipes), against a 14-point swing at six-vs-six. It reproduces exactly here.
+
+**It stays out of the scenario for now, and the reason is the point.** It comes from
+`tools/first-blood.mjs`, a reading tool with no guarded baseline — and this house's rule is
+that a GM-facing page may not carry a figure that cannot be re-derived. The published
+"decided by round five" numbers came out of the guarded lineage and can be checked by anyone
+who doubts them. **"Round five is where it becomes legible, not where it happens" is the
+better sentence, and it is not yet a citable one.** If the measurement gets a guarded home,
+reframe the paragraph around the first disabling blow.
