CNA-VGAP-040: Avatar rendering evidence uses a synthetic one-bone quad; no renderer test draws the bundled 19-bone avatar content

Evidence basis: source-verified at the pinned commit; tests exist (not executed for this page). Claims on this page were checked by reading the CNA source at commit 009d40f5; unless a sentence says otherwise, nothing here was built or executed. Nothing on this page was executed unless the Evidence section says so.

The three avatar pixel programs build their own one-bone quad and run on EasyGL, Vulkan and (through the EasyGL parity corpus) OpenGL4; no renderer test draws the shipped avatar meshes, skeleton or animations.

Identifier: CNA-VGAP-040
Category: Verification gap
Subsystem: Testing & evidence
Status: Open
Verified against: CNA 009d40f5 (009d40f5dd085c4e674d3479675fac84b12b3e0a)
Evidence basis: Source-verified: read at TARGET, not executed
Tests touching this area: Yes: see Current tests
Affected contract: AvatarRenderer real rendering (EnableRealRenderingEXT/DrawRealEXT) with the bundled content

Expected behaviour

The shipped avatar content should be drawn by at least one renderer test with checked output.

Actual behaviour at TARGET

avatar_real_render_integration_test.cpp builds a quad bound to bone 0 (BuildOneBoneQuadModel) and checks three pixels. It and the attach-part and tint-routing programs are registered in EasyGL's and Vulkan's example lists and, via EasyGLParityCorpus.cmake, for OpenGL4.

Source locations

modules/gamer-services/examples/avatar_real_render_integration_test.cpp — BuildOneBoneQuadModel
modules/renderers/easygl/examples/CMakeLists.txt — avatar program registration
modules/renderers/vulkan/examples/CMakeLists.txt — avatar program registration
modules/renderers/opengl4/examples/EasyGLParityCorpus.cmake — the same programs for OpenGL4

Evidence

Checked by reading at 009d40f5; not executed. Corrected from the candidate: OpenGL4 also registers the three programs.

Focused reproduction

No focused reproduction is known. Nothing has been invented here; the evidence above is what exists.

Current tests

Three synthetic pixel programs on three renderers; host unit tests of the avatar API.

Regression test

A render of the bundled avatar at a fixed pose and camera against a golden, on one renderer at least.

Blast radius

Evidence only: regressions in the bundled content or its skinning would not be caught.

Workaround

No workaround is known.
