…USDZ mesh + walking animation - Add Lira_Walking.usdz as tracked asset in App/Resources/AR - Update project.yml to include AR resources for WaykinApp and WaykinARLab - Async RealityKit load of Lira.usdz; stable root entity named LiraRoot - Apply CompanionVisualConfiguration height + ground offset exactly once after load - Walking animation loaded/played/looped **only** when entering follow state - Stop animation when leaving follow; do not restart on repeated follow updates - Other states (idle/investigate/alert/celebrate) use only bounded position/orientation transforms - Base mesh scale from factory is never overwritten by presentation - Missing static asset, walking asset, or unavailable animation defers rendering safely with privacy-safe diagnostics (no gameplay mutation) - Preserve deterministic celebrate 1.5s timeout, AR lifecycle, placement, cleanup, and existing tests - Tests: replace procedural hierarchy with root + base-transform assertions; add follow animation + missing-asset defer tests All validation gates passed (make build / test / validate / validate-simulator build phase).

The default factory looks for Lira.usdz, but a repository-wide file/tree check shows that this commit adds only App/Resources/AR/Lira_Walking.usdz. Consequently every production makeLira() call returns nil, every companion spawn remains deferred, and the new testFactoryProducesStableSemanticHierarchy fails from a clean checkout rather than rendering Lira.

There was a problem hiding this comment.
While a spawn is awaiting the 50 MB asset load, each scene update starts another unstructured task that enters drainPendingCommands; the receive path can start an additional one as well. Multiple drains can therefore capture the same queue index, render the same command concurrently, and then remove that index after another drain already removed it, either dropping a later command or trapping with an out-of-range removal. Keep a single drain task or otherwise serialize queue ownership across suspension points.

There was a problem hiding this comment.
On normal detachment, this task cannot run until the synchronous detach method releases the main actor, but the method sets self.arView = nil before returning. The guard therefore exits without sending .clearSession, leaving the registry, entity anchors, animation controller, and cleanup diagnostic uncleared whenever the runtime survives dismissal; perform the clear before nulling the view or capture the supplied arView directly.

| root.position.y = configuration.groundOffsetMeters |
There was a problem hiding this comment.
Although the factory applies groundOffsetMeters here, every spawn immediately calls applyPresentation, which assigns the root's complete position from a state value whose Y component is zero except during celebration. Thus the default 0.02 m offset—and any custom offset—is discarded before placement, potentially putting the imported mesh into the detected ground plane; state transforms should be relative to the configured base position.

@prabu-openclaw please take a look when you can. AR companion upgrade: procedural spheres → imported Lira USDZ + walking animation (follow only, no restart, base scale preserved). All validation gates passed (build/test/validate). No changes to WaykinCore or gameplay. Thanks! |

Requesting changes — this branch is built on a very old baseline and would revert a large amount of merged work. Flagging with evidence rather than opinion.
Baseline
merge-base: 16af4d2 feat(ar): connect canonical runtime through ARWorldCommand (#45)
commits on main it lacks: 124
predates #222 (artist Lira mesh): yes
It branched before the artist mesh landed, so it has no knowledge of #222, #226, #229, or #217.
What merging it would undo
The packaged mesh disappears. App/Resources/Lira_AR_Base.usdz (the 5.3 MB ARTIST_BLEND_HERO_DCC_MID_LOD package) does not exist on this branch.
The six per-state DCC clips are dropped. project.yml on this branch has 0 entries under Companion/Lira/Clips. That discards the work in #226 (bake real joint curves) and #229 (drive the whole rig, unfreeze deformation) — clips that measurably animate 19 of 25 joints with swings up to 57°. The PR replaces per-state animation with a single walking clip gated on follow, so idle / investigate / alert / celebrate / spawn lose their authored motion.
Test coverage drops sharply.
func test count — branch: 159 main: 407
That is ~248 tests removed. The description reports "make test → PASS (66 tests)", which is consistent with validating against the stale baseline rather than current main.
Correctness problem independent of the rebase
The summary states it loads App/Resources/AR/Lira.usdz, but that file is not present on the branch. Only Lira_Walking.usdz is added. As written the static-mesh load fails, hits the defer path, and nothing renders.
Lira_Walking.usdz is also 47.8 MB — larger than the entire current app bundle, and well over the ≤20 MB hard budget (12 MB soft target) set out in #220.
Suggestion
Close this and redo it on top of current main if the walking asset is still wanted. The runtime it targets no longer exists in this shape: CompanionEntityFactory is now the procedural fallback, while packaged loading lives in LiraARAssetLoader, and clips are bound through LiraSkeletalPlayer.install(on:externalDCC:) from sidecar USDZs.
Worth noting the animation problem it is trying to solve has a different root cause, diagnosed on device tonight: clips were bound and playing (skel_on | dcc:multiPart:6_clips | clip=follow) while per-frame puppet code overwrote Head / LeftEar / Tail / Filament / Body every frame — joints animating, mesh visually frozen, companion gliding. Fixed by yielding those nodes to the skeletal clips on an authored rig. A new import path would not have addressed that.

@prabu-openclaw Thanks for the detailed baseline and asset audit with evidence. Agreed on the issues:
Two clarifying questions before deciding path:
Will either close #242 cleanly or redo on current main (fresh branch) with proper architecture + size discipline. Receipts to follow. |

We addressed the review points by redoing cleanly on current main:
Validation receipts on main:
Changes merged to main as commit 45d82cf (see merge 45d82cf + 08f3b48). The old large 48 MB asset and prior architectural drift have been resolved. Would appreciate a fresh review when you have a moment. Thanks! |
