Conversation
…hing (#2934) Three commands the embed API advertises reported success while doing nothing. Each was broken at a different link, so each needed a different fix. SET_CAMERA had no actuator at all. handler.ts called the store's setCameraRotation, which was `set({ cameraRotation })` and stopped there: every orientation entry point on the camera is relative (orbit, the 90° rotate steppers) or names a direction (setPresetView), so an absolute azimuth/elevation pair had nothing to reach. The host received a requestId ack AND a CAMERA_CHANGED echo of its own numbers while the view never moved. Adds Camera.setRotation(azimuth, elevation) — the inverse of Camera.getRotation, keeping the target and orbit distance, normalizing azimuth into 0-360, clamping elevation to MIN_PHI off the poles (as orbit does), rejecting non-finite angles, and cancelling any in-flight tween so the next update() cannot erase the pose. cameraSlice.setCameraRotation now drives it through a new CameraCallbacks.setCameraRotation, the same shape setProjectionMode already used, registered in Viewport.tsx. RESET_COLORS cleared the wrong channel, wrong in both directions. SET_COLORS bakes into geometryResult.meshes[].color via updateMeshColors; clearPendingColorUpdates empties pendingColorUpdates, the transient overlay channel the lens, IDS, clash and schedule overlays own. So the host's own override survived the reset and another subsystem's claim was destroyed by it. updateMeshColors takes `{ override: true }`, which captures the colors it displaces into meshColorBackup (first write per entity wins), and the new resetMeshColors restores those, re-queues them for the renderer, and leaves pendingColorUpdates alone. The loader's deferred IFC style pass deliberately does NOT pass `override`: those colors are the model's, and backing them up would make a reset strip the model's own styling. ENTITY_HOVERED had zero emit sites in apps/viewer-embed. The SDK's tests pass because they call harness.emit('ENTITY_HOVERED', ...) themselves, proving the SDK dispatches an event the viewer never sent. The viewer's hover pipeline (useMouseControls' throttled renderer.pick -> setHoverState) was already reachable but gated on hoverTooltipsEnabled, which defaults false and has no embed chrome to toggle it; the embed now forces it on (safe — it never renders HoverTooltip) and emits on each hover-target change, subscribing to hoverState.entityId so a pointer drifting within one mesh does not re-post. SET_CAMERA's `zoom` stays unapplied and is now documented as reserved rather than silently dropped: it has no defined meaning on the viewer side and guessing one is worse than saying so. Tests assert effects, not messages — a recording double is what let these ship inert. New: camera-absolute-rotation.test.ts (real pose), the first cameraSlice.test.ts (recording proxy over cameraCallbacks, the same probe that showed zero callbacks), resetMeshColors cases in dataSlice.test.ts (both ownership directions, plus the IFC-style-colors case), handler.effects.test.ts (bridge driven against the real slices) and ENTITY_HOVERED cases in EmbedViewer.test.ts (captured at window.parent.postMessage). Each was checked by reverting the fix.

Every case in camera-absolute-rotation.test.ts started from a camera whose
`up` was already world Y — the one state in which the reset at the end of
`setRotation` cannot be observed. Verified by mutation: deleting
`this.state.camera.up = { x: 0, y: 1, z: 0 }` left all nine tests green.
It matters because `getRotation` derives azimuth from the UP vector whenever
it has a horizontal component (`upLen > 0.01`) and only falls back to the
position when up is vertical. A camera restored from a BCF viewpoint takes
its up straight from the file (Viewport.tsx:926, `camera.setUp(viewpoint.up…)`),
so a top-down viewpoint arrives with up = (0, 0, -1). Measured with the reset
removed: `setRotation(120, 30)` writes the right position but `getRotation`
reports azimuth 0 — the same "the command did nothing" symptom as #2934, one
layer down.
The new case sets that pose up explicitly, asserts the precondition (stale up
reports azimuth 0), then pins the round trip and the re-seated up. The
deletion mutation now fails.

Replay rotations received before renderer registration.
setCameraRotation() treats the actuator as optional, then records the rotation. If SET_CAMERA arrives before Viewport registers callbacks, the command is acknowledged without moving the renderer. setCameraCallbacks() later only stores the callback object, so the recorded rotation is never applied.
Retain the latest unactuated rotation and apply it when setCameraCallbacks() receives setCameraRotation, or delay command completion until the actuator exists. Add a test that registers the callback after the command and asserts one actuator call.

Do not propagate a non-finite target.
isUsableDistance() replaces a bad radius, but it does not validate target. setTarget() permits non-finite coordinates. A non-finite target makes every new position coordinate non-finite at Lines 523-527, so setRotation() does not recover the pose as its contract states.
Validate the target before resetting animation and calculating the position. Use a documented finite fallback or reject the command without further mutation. Add a regression test for a non-finite target.

The change is right -- SET_COLORS never wrote that channel -- but a host that had been sending RESET_COLORS to clear a lens, IDS, clash or schedule overlay was relying on that side effect, and it is gone. That is a behaviour change on a published surface, not only a fix. RESET_COLORS restores only the entities in the viewer's primary geometryResult, which addModel (modelSlice.ts) sets from the FIRST model only. In a federated embed both commands ack success and the later models stay recoloured. Verified by running, against the real slice via createDataSlice: backup after SET : [[1,[1,0,0,1]]] <- 999 absent pending after SET : [[1,[0,1,0,1]],[999,[0,1,0,1]]] <- 999 IS sent pending after RST : [[1,[1,0,0,1]]] <- 999 never restored And with geometryResult null, updateMeshColors returns before the backup capture, so meshColorBackup stays null and resetMeshColors is a silent no-op: NULL: pending after SET : [[1,[0,1,0,1]]] NULL: backup after SET : null NULL: pending after RST : [[1,[0,1,0,1]]] Documenting, not fixing: a real fix has to decide whether the backup key space becomes model-scoped (expressIds are per-model and the federation registry maps them to globalIds) or whether the command refuses what it cannot back up instead of acking it. That is a design call, not a patch.

All three confirmed. One fixed, two handed back with recommendations — pushed Reproduced rather than reasoned aboutProbe against the real Your numbers reproduce exactly, including the unreachable "Federation mode" branch in Fixed: the changeset gap
Handed back 1: the federation fix is not contained, and I would rather not guess
Recommendation: take your second option for now — refuse the entities it cannot back up rather than acking them — and file the model-scoped backup separately. Guessing the id space would restore colours onto the wrong entities in a federation, which is worse than the current under-clear. Handed back 2: the auto-close linkage, verified
Not touched: hover picking forced on

Closes the three inert commands in #2934. All three were genuinely inert, each broken at a different link — "advertised but doesn't work" was one symptom over three causes.
SET_CAMERA — sender and handler existed; the store action was a dead end
grepfound exactly one caller ofsetCameraRotation(the bridge), and the action only wrote a field.CameraCallbackshad no absolute-orientation member —orbit/rotateLeft/rotateRightare relative,setPresetViewnames a direction — andCamerahadgetRotation()with no inverse.New
Camera.setRotation(azimuth, elevation)— the inverse ofgetRotation: keeps target and orbit distance, normalises azimuth, clamps elevation off the poles, rejects non-finite input, and cancels an in-flight tween soupdate()cannot erase the pose. Nine tests on the real camera pose, including no drift over 20 repeats and tween supersession; each confirmed load-bearing by reverting the fix.RESET_COLORS — wired to the wrong channel, and wrong in both directions
SET_COLORSbakes intogeometryResult.meshes[].color;RESET_COLORSwas clearingpendingColorUpdates— a different channel.pendingColorUpdatesis written byuseClash.ts(7 sites),useIDS.ts,useOverlayCompositor.ts,useCompareOverlay.ts,ClashPanel.tsxand the SDK viewer adapter. A hostRESET_COLORSdestroyed whichever of those held a claim.Worth noting for the ownership model: the documented records (
lib/clash/visibility-ownership.ts,lens-visibility-ownership.ts) cover the visibility channels only. There is no colour-ownership record, so the correct fix is to not touch that channel at all rather than to release it.updateMeshColors(updates, { override: true })now captures displaced colours into ameshColorBackup(first write per entity wins) andresetMeshColors()restores them, leavingpendingColorUpdatesuntouched.This is a correction to an earlier attempt on
upstream/embed-dead-surface-fixes, which backed up unconditionally —useIfcLoader.ts:1803runs the deferred IFC style pass through the same action, so that version would have stripped the model's own IFC colours back to pre-style defaults. Theoverrideflag confines the backup to host overrides; both halves are pinned.ENTITY_HOVERED — declared and SDK-plumbed, never emitted
grep -rn "ENTITY_HOVERED" apps/viewer-embed/srcreturned nothing. The protocol declares it and the SDK tests pass by callingharness.emitthemselves, so nothing downstream noticed. Two links missing: the hover pipeline is gated onhoverTooltipsEnabled, which defaultsfalsewith no embed chrome to toggle it, and there was no emit effect. Both fixed inEmbedViewer.tsx.Tests enter at
setHoverState— the store action the pick path calls — and assert what reacheswindow.parent.postMessage, including no re-post on pointer drift within a mesh and a fresh post on a new entity.Deliberately not fixed
zoomonSET_CAMERAhas no defined viewer-side meaning (factor? distance? relative to what?). Now documented as reserved in both packages rather than silently dropped.CAMERA_CHANGEDnever fires for real navigation) and the eight URL params are out of scope and remain open — this PR does not close Embed API: SET_CAMERA, RESET_COLORS and ENTITY_HOVERED are inert, and 8 URL params are never applied #2934 on its own.Limits
