# Meshnet llama.cpp patch stack

This directory is the only project-owned fork boundary for llama.cpp. It is
locked to `e920c523e3b8a0163fe498af5bf90df35ff51d25`; changing the pin requires
updating the recorded tree/blob assumptions and reviewing every patch anew.

## Ordered series

1. `0001-cmake-reserve-meshnet-patch-stack-abi-marker.patch` adds only an
   interface-library marker used to prove the patched source was configured.
   It has no execution, transport, model-loading, or semantic effect.

Future patches may implement only the ADR-0020 local seams: range-aware tensor
loading, endpoint ownership, architecture-defined intermediate boundaries, and
layer-filtered KV/session mapping. Meshnet routing, Tracker, gRPC, relay,
billing, authentication, and telemetry must remain outside this directory.

`scripts/llama_cpp_dependency.py fetch` reads the in-repo manifest and checks out
only its exact commit as detached HEAD in `build/llama.cpp/source`, an ignored
build workspace. It verifies the exact commit/tree and baseline blobs before use. A
later offline `fetch` may reuse that cache only after the same clean identity
verification; an attached branch, tag/repository override, arbitrary destination,
symlinked workspace, dirty checkout, ignored injected file, or tracked-file
modification hidden by Git index flags is refused. The tool
validates every patch digest and context
with `git apply --check`, then applies the series in `patches/series` order.
Tracked executable modes are checked physically when Git reports
`core.filemode=true`; on mounted filesystems without POSIX mode fidelity, the
locked index tree remains the canonical mode record while every working-file
blob is independently re-hashed.

## Current semantic boundary

The stock pinned build is **infrastructure evidence only**. Per DGR-017,
GLM-5.2 can use a dense-MLA compatibility fallback at this point; a successful
build or `llama-cli --version` does not show native DSA/IndexShare, GLM semantic
acceptance, numerical parity, performance, or route certification. DGR-018 and
DGR-019 own those checks. Dense Llama remains only a later structural fixture.
