initial seed: retrofit campaign lineage from local working trees

panvk-bifrost campaigns (r1..r4 Vulkan compositor + r5.video1 Vulkan video decode) shipped before this repo existed; the deliverable patches live in marfrit-packages, but the reasoning chain, phase docs, and source-state evidence lived only in local working trees on the development host. This retrofit imports: - mesa-panvk-bifrost/ — r1..r4 era phase docs (iter1..iter18) (libmali stub blobs at iter18/blob/ excluded — 109MB of RE artifacts replaced with a README pointer) - mesa-panvk-bifrost-video/ — sibling campaign phase docs + probe - evidence/ — frozen .tgz source snapshots at each milestone (basis for the 0005 patch diff generation) Future iterations should branch off here from day one, so each iter is a commit rather than a snapshot. See [[feedback-session-local-process-pins]] for the process drift this retrofit closes. Total: 1.9 MB across 124 files. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

+→ 240 frames / 4.352s = ~55.1 FPS sustained.
+  Almost certainly vsync-locked to display refresh (60Hz on PineTab2).
+  user+sys CPU = 0.43s out of 4.35s wall → ~10% CPU, the rest is GPU+vsync wait.
+
+===== OPERATOR VISUAL CONFIRMATION =====
+2026-05-19, mfritsche: "Ich hab' ihn gesehen." — vkcube's rotating textured
+cube was visually verified on the PineTab2 screen during the run.
+
+===== DMESG =====
+No panfrost faults, no MMU faults, no GPU error messages logged during or
+after the 3 vkcube runs.
+
+===== KEY OBSERVATIONS =====
+
+1. PanVk-Bifrost handles the canonical Vulkan reference application end-to-end:
+   - VK_KHR_wayland_surface creates a surface against the Plasma compositor
+   - VK_KHR_swapchain allocates swapchain images
+   - vkAcquireNextImageKHR + vkQueuePresentKHR cycle works for 240 frames
+   - Rotating MVP matrix per frame, textured cube vertex buffer, depth test
+   - 55 FPS sustained on a single-core (MC1) Mali-G52 — vsync-locked
+
+2. The "present support = false" line in vulkaninfo (from an off-line surface
+   query) is misleading — with an actual Wayland surface in play, vkcube
+   negotiates a present-capable swapchain without issues.
+
+3. Validation layer reports zero warnings even with --validate.
+
+4. This is the first real-app smoke test in this campaign and it passes
+   without any code path failing.
