 The defence ladder is legible in the log too — `Ben → Redcap A: 26 SUCCESS — dodged
 (10 vs 45, -30 for defences already spent)` — a 75% dodge meeting the second attack of the
 round at 45.
+
+## R-264 — the harness was fighting a different animal
+
+Reading a narrated supporter fight (R-263, the first time any fight in this project could
+be read rather than totalled) showed it being hit on `armR` and `head`. It has wings. It
+has never had arms. Three defects, all in the pipeline every published number comes from.
+
+**1. It located hits by species, not body plan.** `simulate.mjs` read `defender.species`
+where the game writes `spec.bodyPlan ?? spec.species ?? "baseline"` into `speciesProfile`
+(build-packs.mjs:294). Four creatures were fought human-shaped: the barghest, the kelpie
+and the church grim on two legs with arms, and **the supporter with no wings at all**, so
+the fight its own tactics call the one the agents can win could not occur in a measured
+fight.
+
+**2. Armour was one scalar for the whole creature.** `worn + naturalArmour`, applied
+everywhere, and the harness's locations had no armour field at all. So bare wings, the
+grounded halving and the vital exemption — R-254 and R-255, most of a session's design —
+were invisible to every number. Worn armour was summed the same way, which put a stab
+vest on a cleaner's head.
+
+**3. Nothing was ever grounded.** A wing could be ruined and the creature kept flying,
+because the harness never changed a body mid-fight.
+
+**The fix, in the game's own order.** Locate first, then apply what that location carries:
+`locationArmourFor(slot.armour + naturalArmourOn(slot, exposedHideFor(hide, grounded,
+kind)), worn, kind)`, every term imported. A ruined wing now calls `groundedPlanFor`, and
+the wounds carry across by severity through `remapLocationDamage` — the same function the
+actor's `_preUpdate` uses.
+
+**A bug of mine that no guard would have caught.** `remapLocationDamage` returns
+`{ damage, moved, rescaled }` and my first draft passed the whole object where a damage
+map was expected, so **every wound a creature was carrying was forgiven the moment it came
+down**. check-lethality would have passed it happily: fewer wounds means a longer fight,
+which reads as a number moving, and the whole point of this commit is that numbers move.
+Found by probing a landing by hand, not by the suite. The engine destructures it the same
+way at ringbrp.mjs:462, which is where I should have looked first.
+
+**What it cost. 20 of 47 creatures moved, 18 deadlier and 2 less.**
+
+| | wiped | down of 4 |
+|---|---|---|
+| **The supporter** | 69.3% → **25.1%** | 3.38 → 2.16 |
+| The stanchion | 31.9% → 37.4% | 2.29 → 2.52 |
+| Nuckelavee | 16% → 20.3% | 1.70 → 1.98 |
+| Long walker | 64.1% → 68% | 3.18 → 3.32 |
+
+The supporter falls from second deadliest in the book to fourth, and that is the correct
+direction: it was being measured as a 30-hit-point creature in uniform armour 9 that could
+not be grounded, and it is actually a creature you can put on the floor, after which most
+of it is armour 4. The small rises everywhere else are the party's own armour no longer
+covering locations it never protected — a torso vest stops covering a head.
+
+Focus fire was re-recorded too: 30 of 47 measurable now rather than 31, worth 8 points
+against a pair and 12 against three or more, best case 3 × Spriggan at 38.9% → 55.5%.
+
+**And check-focus caught the page overclaiming, which is what it is for.** Its claim-check
+failed on the new numbers: focus fire still helps in all 30, but only 28 clear their own
+noise where all 31 once did, and the page said "each time". The guard was asserting more
+than the page needs to: the bestiary prints the above-noise COUNT from the artifact and so
+cannot overstate it however it moves, and what the page actually asserts outright is that
+concentrating fire helps. The guard now checks exactly that, and the page rewrote itself
+to "in 28 of them" on regeneration.
