 Result on 2026-07-18:
 
-- canonical pipeline now uses a fixed MSRV/toolchain, policy checks,
-  full-format workspace test command, `clippy`/`doc`/`cargo deny` gates and
-  typed manifest parsing in `xtask`;
-- `rpath`/offline mode is still useful for synthetic local checks;
-- full online dependency resolution remains unavailable in the sandbox.
+- canonical pipeline passes locally with Rust 1.97.1: formatting, policy,
+  shader provenance, workspace tests, `clippy`, docs and `cargo deny` are
+  executed through `cargo xtask ci`;
+- internal path dependencies are version-pinned and the Windows-only winit
+  graph enables only `rwh_06`, excluding Unix window-system dependencies;
+- `cargo deny` runs without advisory exceptions in the supported Windows graph.

+- Windows x86_64 local smoke passed again on 2026-07-18 with Rust 1.97.1, the
   system Vulkan loader 1.4.350, and an AMD Radeon Pro WX 3200 Series;
 - the smoke created a Win32 surface and swapchain, presented 300 frames,
   exercised a controlled resize (three observed resize events and two
   swapchain recreations), and shut down with zero validation warnings and
   errors;
-- the result is configuration-specific evidence, not a substitute for the
