Struct RunOutput 

pub struct RunOutput {
    pub snapshot: Vec<(String, u32, Option<SolidDisplay>)>,
    pub report: SceneBuildReport,
    pub provenance: Vec<(String, String)>,
    pub entity_origin: Vec<(String, String)>,
    pub assembly_poses: Vec<(String, Value)>,
    pub assembly_fixed: Vec<(String, bool)>,
    pub moved_solids: Vec<String>,
    pub imported_colors: Vec<(String, String)>,
}

The delta a SceneRunner::run produces: the displayed KERNEL solids IN ORDER plus the run’s SceneBuildReport. The applier walks snapshot in order, reusing or replacing each entry (see the field docs).

Fields

snapshot: Vec<(String, u32, Option<SolidDisplay>)>

The displayed KERNEL solids IN ORDER. display: Some = freshly tessellated (new, or the handle changed since last emit); None = UNCHANGED — the applier keeps its existing SolidDisplay for this name, whose source_handle equals handle.

report: SceneBuildReport

provenance: Vec<(String, String)>

Eager PROVENANCE: name -> creating-feature id for the run’s FINAL resident SOLIDS (same last-writer-wins fold as the display snapshot). Shipped WITH the run so the main thread can answer SOLID provenance without a cold execute_history — critical once the run lives on a background thread and the main-side registry is cold.

entity_origin: Vec<(String, String)>

Eager ENTITY ORIGIN: face/edge NAME -> ORIGINATING feature id (FIRST writer in timeline order, never pruned — see SceneLayout::entity_origin). Shipped beside provenance so creating_feature can answer “which feature gave this face/edge its name?” (the “Edit owning feature” context action + the Info tab’s creatingFeature) with no cold re-run. Crosses the background-worker seam, so the serde round-trip test asserts it survives.

assembly_poses: Vec<(String, Value)>

Assembly-solver POSE write-backs from this run’s constraint tail: (component feature id, {translate, rotateEulerDeg}) — read RUNNER-SIDE (the kernel assembly session is thread-local to the thread/worker that ran execute_history, so only the runner can see it) and shipped here so the engine folds them into the owning ACOMP features’ inputParams (the pose-authority contract, build-spec §6 step 4). Empty on a no-motion solve — a satisfied assembly must not churn feature fingerprints. #[serde(default)] keeps pre-assembly serialized replies deserializing.

assembly_fixed: Vec<(String, bool)>

isFixed write-backs riding the same fold (the Fixed-constraint lane grounds a component); shape mirrors Self::assembly_poses.

moved_solids: Vec<String>

Names of solids the solve re-posed IN PLACE this run (the display seam: their producing feature may have replayed reused, yet their geometry moved). The runner already defeated the handle-unchanged reuse fast path for these (their snapshot entries arrive Some, freshly tessellated); shipped for observability/tests. Empty on zero-mate/no-motion runs.

imported_colors: Vec<(String, String)>

IMPORTED COLOURS: entity name -> "#RRGGBB" for every solid/face this run left a color scene-metadata record on (STEP presentation entities, read by brep_kernel::io/appearance.rs and stamped by IMPORT3D).

Read RUNNER-SIDE for the same reason as assembly_poses: the kernel’s scene-metadata store is thread-local to whoever ran execute_history, so a main-thread read under a background runner sees nothing. The applier folds these into the engine’s own crate::metadata::MetadataStore WITHOUT overwriting, so the Info window shows an imported colour and a user’s edit of it still wins.

Filtered to the names this run actually produced, so a colour left in the (never-cleared) kernel store by a previous document cannot bleed into this one.
