D3D9 resource forwarding consolidation — 2026-09-22

Pass-5 recommendations 4/5/7: eleven resource wrappers did nothing except call the existing IDirect3DShader9 handler with the same six handler arguments. Their API records now name that handler directly; generated dispatch preserves each API's identity, id, hash, argument count and calling convention.

Query9 Release is deliberately not aliased: it retires an outstanding GPU query before entering shared release. The common resource release still owns parent-device and internally retained allocation handling. Neither body changes. The D3D8 DeleteVertexShader caller now invokes the same shared release directly, preserving its outer three-word stack cleanup. Existing Node fixtures resolve handler names through the API metadata rather than naming deleted wrappers.

test-d3d9-resource-aliases.js creates real buffers, declarations, state blocks and EVENT queries. All twelve family operations go through API-name lookup and generated dispatch. Assertions cover external reference counts, parent-device ownership, GetDevice NULL/success paths, output guards, exact stack advancement and final parent-reference balance. A separate declaration goes through D3D8 DeleteVertexShader. Structural assertions forbid reintroduced forwarding bodies and preserve specialized Query9 Release; deleting one alias in memory makes the test fail. This is a consolidation regression, not a native lifetime oracle.

Verification:

• New name/dispatch/lifetime regression and its missing-alias negative control.
• Existing buffers, EVENT query, direct/worker occlusion query, selective and typed state blocks, material/light, viewport/scissor, typed/float constants, clip-plane, adapter/parent-lifetime and real COM-to-software-renderer tests pass (the latter is Node-only, with no DOM/WebGL).
• Metadata generation, append-only API ids, generated dispatch freshness, hash table, handler ESP, generated epilogues, fragment balance, quiet inventory and test-tier membership pass. Metadata comparison against HEAD confirms only the eleven intended handler aliases differ.

The duplication baseline tightens from 134 groups / 522 allowed members to 131 / 509. Eleven forwarding functions disappear, Texture9 GetDevice is no longer a duplicate-group member, and the stale VB clipper fallback allowance is removed (its ABI was changed in the earlier clipper correction). No new allowances are added. Quiet inventory remains 248 manual + 22 metadata entries.

No browser sweep, native capture, performance measurement or full-release build is claimed. Remaining COM/string duplication, quiet API behavior and the queued SHRegGetUSValueA native capture keep the overall review open.
