       126 of 126 rows agree, and the undamaged library is unchanged at 4,252.
 
+      **Widened again, this time across designs.** `bridge/DumpDamaged.java`
+      takes `every:N` and samples the library rather than naming designs, which
+      is how the shapes and construction a hand-picked list never covers get
+      asked about. At `every:40` that is 1,638 states, and it found two more:
+
+      - **A weapon too big for one location** has the rest of itself in the
+        next one, and it is one weapon. A Victor VTR-9Ka's autocannon fills
+        nine slots of an arm and one of the torso beside it; blowing the arm
+        off left helm counting a whole autocannon that was no longer there,
+        worth 465 points of offence. The halves are now paired - but only when
+        there are exactly two of them and they account for the whole item. A
+        Chameleon Light Polarization Shield is spread over half a design a slot
+        at a time *by construction*, and pairing on the name alone took a
+        Scarecrow's shield out with its arm.
+      - **An engine only runs hot when it is hit if it is a fusion or fission
+        plant.** An internal combustion engine takes the critical and makes no
+        extra heat, so a SecurityMech with its engine shot out is worth what it
+        was.
+
+- [ ] **What the sampled damage corpus still disagrees about.** Four kinds, all
+      found by `every:40` and none of them yet understood. Reproduce with
+      `DumpDamaged.java out.jsonl every:40`; the curated list is what the
+      committed test runs, and it passes at 154 of 154.
+
+      - **A blown-off arm holding a big gun**, +8 to +9 defensive on a Cerberus
+        MR-V3, an Ebony MEB-12, a Huron Warrior and a Thunder Hawk TDK-7S. All
+        four carry a Gauss Rifle or a TSEMP Cannon in the arm, which suggests
+        an explosive penalty MegaMek keeps charging for a weapon that is gone.
+      - **Modular armour on a stripped design**, +97.5 on an Enforcer III
+        ENF-7D - exactly 39 points of plate at 2.5. MegaMek counts modular
+        armour as part of the location's armour, so stripping the location
+        takes it too; helm adds it on top of a location it has already zeroed.
+      - **A Devastator DVS-X10 MUSE EARTH's movement gear**, hundreds of points
+        out on a hip or leg actuator hit and a few points out on a gyro hit.
+        An XTR one-off, so it is likely a movement system helm reads and
+        MegaMek recomputes differently once the legs are damaged.
+      - **A Scarecrow UCU-F4 run dry**, 3 points of defence. The smallest of
+        them and probably an explosive penalty on a magazine one of us empties
+        and the other does not.
+
 - [x] **A catalogue small enough to ship.** `helm catalogue` writes the fields
       the rules actually read and drops the rest: the bridge dumps a
       `namesVector`, a `techAdvancement` and several static tables on every one
