Subject: [PATCH] docs: vehicleSubSystems follow-ups -- recharge dial + leak
 wipe done

Mark SegmentArc270 (recharge dial) and BitMapInverseWipe::Execute (LeakGauge) done;
refine the remaining follow-up list with the honest blocker/scope for each (seek
plot blocked on attribute + sampler; eject wipe needs a new base; secondary lamp/
counter raw reads = the heat-leaf-branch re-base; ConfigMapGauge overlay needs the
ModeManager).

 ## Remaining polish (non-blocking follow-ups)
-- Two minor cluster children deferred as marked NULLs: the `SegmentArc270` recharge dial (WeaponCluster) +
-  the `BitMapInverseWipeScalar` eject wipe (BallisticWeaponCluster) — their ctors are placeholders in
-  btl4gaug.hpp (the `SegmentArc270` @004c6244 body + a `BitMapInverseWipeScalar` class need reconstruction).
-- `SeekVoltageGraph::Execute` + `BitMapInverseWipe::Execute` are minimal-safe (vtable-complete, non-crashing)
-  — the full seek-voltage plot + the reveal-wipe column math are deferred.
-- Many cluster child value pointers read raw subsystem offsets (0x31c/0x324/0x334/0x364/0x43c/…) still on
-  the non-byte-exact heat-leaf branch — marked BEST-EFFORT; they render but may show wrong/zero data. The
-  authentic fix is the heat-leaf-branch re-base (the same §10 deferred item for the Sensor RadarPercent
-  gauge) or per-field bridges like the aux-screen one.
-- `ConfigMapGauge`'s control-mapper state loop is guarded off (raw App ModeManager offsets, `DAT_00518eb8`
-  unrecovered).
+- ✅ **`SegmentArc270` recharge dial DONE** — reconstructed (@004c6244, engine SegmentArc + a Scalar
+  connection + the 0.75 span factor) + wired into WeaponCluster, reading the real `PercentDone` attribute.
+  Render-verified: the green segmented recharge circles draw in the weapon panels.
+- ✅ **`BitMapInverseWipe::Execute` (LeakGauge) DONE** — the authentic vertical-segment reveal wipe
+  (@004c5d08), driven by the `CoolantMassLeakRate` attribute.
+- **`SeekVoltageGraph::Execute`** (the seek-voltage curve plot in the Energy/Myomer clusters) — still a
+  minimal-safe no-op. BLOCKED: it needs (a) the four seek-voltage attribute indices resolved (the ctor's
+  `FindAttributeIndex` still returns -1 — the summarised stub) and (b) the subsystem's live seek-voltage
+  sampler (`Emitter` vtbl+0x3c) — so even a reconstructed plot would draw nothing until those land.
+- **`BitMapInverseWipeScalar` eject wipe** (BallisticWeaponCluster) — still a marked NULL. Needs a new base
+  class (the unnamed @004c5e84 wipe base, vtable 0x518a58) + the @004c61c8 ctor. Very low value (the eject
+  indicator only shows during a reload).
+- **Secondary raw value-pointer reads** — the fail/jam/fire lamps + ammo counters read raw subsystem offsets
+  (0x31c/0x320/0x324/0x334/0x364/0x43c/…) on the non-byte-exact heat-leaf branch → they render but show
+  wrong/zero data. NOTE: the KEY gauges already read via the engine ATTRIBUTE system and show real data
+  (temperature bars, the recharge dial, generator voltage, coolant leak); only these secondary lamps/counters
+  are affected. The authentic fix is the heat-leaf-branch re-base (the same §10 deferred item for the Sensor
+  RadarPercent gauge) — a large, regression-risky change to the working combat/heat subsystem code — or a set
+  of per-field bridges like the aux-screen one.
+- **`ConfigMapGauge`'s control-mapper state overlay** — guarded off (raw App ModeManager offsets, `DAT_00518eb8`
+  unrecovered); the base joystick bitmap draws.
 - The **separate** dev-gauge window (960×384) didn't appear in the headless test run (the panels render in
   `BT_DEV_GAUGES_DOCK=1` docked mode); the separate-window path is existing dev-gauge infra, unrelated to
   this reconstruction.
