# Sweep36 editable supported sweep

Open `sweep36-supported.blend` in Blender5.2. Playback and editing use native
Geometry Nodes, ordinary drivers and animation curves. No external geometry
cache, custom playback handler or Python execution is required.

Select `Sweep36 | Constructive supported action`. Play frames1–240 at60fps;
frame241 is the exact four-second endpoint. `Body contribution` is the public
control:0 removes the added body participation,0.5 reduces it and1 restores the
selected supported sweep. Its0–1range is one coupled family. Turn, travel,
rotation and lowering are driven together; six helper values are outputs rather
than independent certified controls. The original feet remain fixed throughout.

At1, the family uses nominal10degree turn,0.070forward travel,0.012lowering,
9degree pitch and−0.010lateral travel. Native curves multiply those amplitudes;
they are not all simultaneously reached. Do not interpret the material pivot as
a recovered physical center of pressure. The movement uses authored constraints,
not measured forces or a complete source-motion reconstruction.

## Shape ownership

The original `C164 | Body-owned convex core` receives rigid placement before
composition, preserving its exact shape. Both original independent180 upper
thigh tasks receive their own transformed hip and fixed ankle. The198 analytic
lower ellipse/taper and currentG endpoint finish each thigh. The existing0.12
constant-width hip union combines those source parts. No height-weighted final
surface warp remains. The original shoulders, analytic arms, tail and neck
attachment use the same rigid body transform; head attention stays independent.

Original transverse thigh scales, material topology, ellipse/taper parameters,
arm material length and section profiles remain the source. The lower attachment
is not globally convex even at rest; the documented guarantees are positive
sections, retained radius behavior and bounded sampled centerline curvature.
Both hidden ankle closures and actual composed contours are checked separately.

The original arms embed part of their medial surfaces inside the Body. This
candidate retains that relationship and tests it for increased penetration at
the same local arm articulation. It does not claim zero arm/body intersections.
The broom has a separate clearance test outside the intended hand grip.

## Editable scope

Change Body contribution, inspect the whole action, then return to1. Native
verification changed0.25,0.75and0, restored exactly, saved/reopened with scripts
disabled and repeated an edit/reset. The visual package also includes actual
0/0.5/1renders. Values outside0–1, independently disconnected helper drivers,
other inherited pose controls, different steps or different arm trajectories
need new profile, attachment, contact and visual checks.

The source geometry and profile tasks remain editable. Do not sculpt evaluated
output and expect its material ownership to update. Original named attributes
encode material rows, radius profiles, hidden closure and pigment ownership;
changing their source topology requires regenerating or transferring that data.

The extension sources are included for audit and rebuilding inside the Mozu
repository. They import preserved ancestor scripts and source assets and are
not a standalone Blender addon. The saved native itself is self-contained.
Windows pilot/source replicas retired after verified Mac backup must be restored
before rebuilding; `replica-backups.json` gives the exact paths and SHA256 values.

## Limits

This is an owner-review candidate. No adopted model/motion registry is replaced.
The fifteen architecture issues and eleven full-motion release gates remain
open at their original scope. Main-agent implementation and review do not
constitute independent sign-off. Runtime export, arbitrary combined controls,
physical load recovery, stepping, pickup/release and new hand/finger design are
outside this change. See REPORT.md and the bound evidence for the checked domain.
