Move ALL paged-attention content out of the stock backend/cpp/llama-cpp backend and into backend/cpp/llama-cpp-localai-paged, so the stock backend is pure upstream llama.cpp and the paged backend owns and applies its own vendored patch series. - Delete the dead early-exploration scaffold backend/cpp/llama-cpp/paged/ (kernel/w4a16 Marlin scaffold, standalone paged_kv_manager, bench/loadgen, its own 0001-0002 patches, dense-era design docs, tests). Zero references repo-wide. - Move backend/cpp/llama-cpp/patches/ (the 28-patch paged series + paged/README + 3 operational docs, plus the kernel/ scaffold patch and the top-level paged README/BENCHMARKS) to backend/cpp/llama-cpp-localai-paged/patches/. The stock backend keeps no patches/ dir; it had no non-paged base patches. - Purify the stock backend: remove the LLAMA_PAGED make variable, the patches/paged apply loop, and the LLAMA_PAGED passthrough to prepare.sh; remove the paged-series handling from prepare.sh. The stock llama.cpp target now only clones the pin and applies its own (currently empty) base patches/ series. The runtime paged option hooks in the shared grpc-server.cpp are untouched (inert without the patches). - The paged backend's Makefile now applies its OWN patches/paged/0*.patch onto each freshly cloned tree via strict git apply (apply-paged-patches), after the copied stock infra clones the pin and applies base patches. - Repoint every reference to the old patches/paged path: the upstream canary workflow + apply script, bump_deps.yaml, gallery/index.yaml, the docs, backend/index.yaml, backend-matrix.yml, the top-level Makefile comments, and the moved PIN_SYNC / README docs. Drop the now-removed LLAMA_PAGED=on build-toggle from comments. Verified: the full 28-patch series applies strict-clean (git apply, exit 0) to a clean ggml-org/llama.cpp checkout at the pinned c299a92c, and the repointed canary apply script resolves and applies the series end to end.
