🎯 Problem

qvac-fabric v10549.4.0 adds Ternary Bonsai support on CPU, Metal, CUDA and Vulkan (tetherto/qvac-fabric-llm.cpp#283–#286). @qvac/fabric still builds against 10549.3.0.

📝 How

• packages/fabric/vcpkg.json: qvac-fabric version>= 10549.3.0 → 10549.4.0.
• packages/fabric/package.json: 0.17.0 → 0.17.1.
• packages/fabric/CHANGELOG.md: a 0.17.1 entry listing what the fabric bump carries. It also records the Windows backend-module packaging from QVAC-25088 feat[windows]: support dynamic backend loading #4520, which landed after 0.17.0 with no changelog entry and ships in this release.

fabric is the only package that depends on the qvac-fabric vcpkg port (git grep -l "qvac-fabric" origin/main -- "packages/*/vcpkg.json"). The addons on the npm @qvac/fabric runtime (llm-llamacpp, embed-llamacpp, model-fit, ocr-ggml, translation-nmtcpp, classification-ggml, vla-ggml) get 0.17.1 through their existing ^0.17.0 range, so none of them is bumped here. default-registry.baseline is untouched.

Links:

• Fabric: QVAC-25280: add Ternary Bonsai Vulkan support qvac-fabric-llm.cpp#286, tag v10549.4.0 → b9bf3a820
• Registry: QVAC-25280 bump[qvac-fabric]: publish 10549.4.0 qvac-registry-vcpkg#386 (merged)
• Validation (overlay, closed unmerged after the registry merges): QVAC-25280 chore: DO NOT MERGE, overlay-validate the 1 fabric consumer against qvac-fabric 10549.4.0 #4696

🧪 Tested

• Phase A validated the consumers against temp-10549 @ b9bf3a820 in QVAC-25280 chore: DO NOT MERGE, overlay-validate the 1 fabric consumer against qvac-fabric 10549.4.0 #4696: Fabric, Classification-ggml, VLA and nx (llm, embed, model-fit, ocr, translation) plus the mobile lanes are all green.
• The registry port was built locally at @10549.4.0 with isolated roots.
• The registry PR has merged, so version>= 10549.4.0 resolves from the published port.

⚠️ Breaking
