+## ⚠ CRITS NEVER ROLL FROM WEAPON FIRE — the trigger is un-exported + the sink is a stub (2026-07-29) [T1]
+The authored crit machinery exists and is reconstructed — `Mech__DamageZone::CriticalHit @0049ccc4`
+(half the damage to armour, half to ONE critical subsystem chosen by `criticalWeight`, capped by
+`damagePercentage`) — but **nothing in the port calls it**. Raw byte-scan of the binary: exactly ONE
+call site, `@0x4a0461`, inside the **un-exported gap** (no decomp covers `0x4a03xx-0x4a05xx` — the
+same dark region as the `0x37c/0x388/0x38c` pick writer), so the crit TRIGGER CONDITIONS (per-hit
+chance? threshold crossing?) are unknown and unreconstructed. Second layer:
+`MechSubsystem::TakeDamage` is an **empty bring-up stub** (`btstubs.cpp:179`), so even a wired
+caller would measure a delta of 0 through `ApplyDamageAndMeasure` (and the weapon-family overrides
+chain to the engine base whose private-zone write is the zero-`damageScale` no-op — see the
+subsystem-zone finding above). Net: **the Critical view lights ONLY on zone destruction
+(`SendSubsystemDamage`, direct pin) or ammo cook-off (`DistributeCriticalHit`, direct pin), never
+from accumulating fire.** The DISPLAY is fine — the paper doll shows ZONE ARMOR, the Critical panel
+shows SUBSYSTEM crits (different data by design); the panel's near-permanent emptiness is the gap.
+Field signature (night 6, Conn Man): "Armor panel damage. Critical damage display did not show any
+crits." **#28 (vital-subsystem-crit death path) is very likely blocked by the same missing caller.**
+Recovery: raw-disasm the `@0x4a04xx` container (#60-class gap work) for the trigger; dump
+MechSubsystem vtable `0050e210` slot `+0x24` for the real TakeDamage body; wire both. Tracker: #80.
