Objective

Implement the complete callable signature surface for imaging abstractions, Skia adapter, PrimMesher, SimpleRenderer, and MeshFoundry.

Deliverables

Map codec interfaces, managed-image data, meshing geometry/types, renderer interfaces, and all public methods and properties.
Keep native Skia and codec implementation details behind optional adapter boundaries.
Preserve generic and collection element types used by downstream samples and tests.
Use standardized failing bodies only.

Validation

Reach 100% catalog coverage for the five owned assemblies.
Build all owned crates and their docs on the default feature set.
Compile representative downstream calls for mesh construction and rendering.

Prerequisite

Stage 0 project setup is complete. Do not implement production behavior in this milestone.

Project constraints

Implement the public surface in native Rust only; no CLR hosting, FFI bridge, subprocess, RPC, or C# fallback.
Preserve recognizable API concepts while applying the documented Rust mapping rules.
Do not weaken parity requirements or add functional behavior outside this issue.
Update the API mapping, coverage report, public docs, and relevant handover status in the same change.

Implemented and pushed in commit 8ca986d. Generated the complete failure-only Rust signature surface for LibreMetaverse.Imaging.Abstractions, LibreMetaverse.Imaging.Skia, LibreMetaverse.PrimMesher, LibreMetaverse.Rendering.Simple, and LibreMetaverse.Rendering.MeshFoundry: 23 catalog types and 250 callable members. Added project-owned codec/bitmap boundary types (no SkiaSharp or platform-native dependency), preserved generic and collection element mappings, wired the owned crates, updated the mapping ledger, coverage report, README, and handover, and added representative typed PrimMesh/SimpleRenderer/MeshFoundry downstream compile calls plus exact NotImplemented member-ID assertions. Review verified exact catalog type/member-ID equality and standardized failing bodies. Gates passed: shim and mapping generator checks, cargo fmt, git diff --check, focused five-crate cargo check, workspace cargo check, workspace test compile (--no-run), workspace clippy with -D warnings, workspace docs, and the focused rendering_shims test (2 passed). The documented Stage 0 generated behavioral parity suite remains intentionally red and was not treated as a shim gate.
