 The gate emits only engine-bound Chromium claims backed by the compiled Blender native/WASM path. P7/P8/P9 history remains immutable evidence, the authorized provenance baseline is not historical restoration, and the remaining inventory is not silently marked complete. P11-004 is the terminal pointer until a separately authorized continuation is created.
+- authorized continuation: `WBV2-P12-000`

+Domain expansion may continue under a new manifest root. This does not change P11 evidence or the authorized-rebaseline-only release scope.

+Domain expansion is authorized after P11 engine-bound evidence. P12 first builds a conservative capability ledger from existing receipts, then adds scene, authoring, viewport, and non-mesh coverage.

+This ledger reuses existing P1-P6, P10, and P11 manifests as read-only evidence. It records current artifact drift instead of rewriting historical hashes and does not rerun already completed Blender or Chromium checks. Only P10/P11 engine-bound receipts are treated as current engine evidence; the remaining inventory stays explicit.

+The domain gate combines the conservative batch ledger with engine-bound Chromium receipts for scene/object, material/animation, and viewport/non-mesh behavior. Existing evidence was reused read-only; only verified domain claims are emitted. The remaining inventory and provenance limitations stay explicit. P12-005 is the terminal pointer until a separately authorized continuation is created.
