codingest-mcp — MCP server frontend for code-tree graphs.
The entire server (tool surface, Cypher pipeline, code-tree
activation on set_root_dir, file watching) is imported from the
kglite-mcp-server library crate; this binary is only the process
shell. The one thing it injects is the code-tree builder: via
[kglite_mcp_server::CodeTreeHooks] it points the server's
set_root_dir build path at THIS workspace's codingest crate.
KGLite deleted its own in-tree code_tree on 2026-07-16, so the
server now REFUSES to build a workspace without builder hooks —
injecting them here is what keeps the MCP surface working, and it
makes codingest the sole builder behind it. Graph correctness is
guarded by the frozen golden digests in crates/codingest/tests/
(see PARITY.md), captured while codingest was verified byte-for-byte
identical to the last in-sync in-tree authority.
