One shared, detached daemon per project root: every `codegraph serve --mcp` is a thin stdio<->socket proxy (Unix socket / Windows named pipe) to it, so N agents in one repo share a single file watcher, SQLite connection, and tree-sitter warm-up instead of N copies. The daemon outlives any single session and reaps via client-refcount + idle timeout; `CODEGRAPH_NO_DAEMON=1` opts out. Hardened during review: detached-process lifecycle (preserves the #277 watchdog via the proxy; the daemon no longer orphans on host SIGKILL), atomic lockfile + pid-verified stale-clear (no double-daemon on concurrent startup), realpath root canonicalization. Validated on macOS, Linux (Docker - 3x fewer inotify watches for 3 agents), and Windows (named pipes); A/B confirms byte-identical tool output vs direct mode. Closes #411.

* Resolved package version, computed once at module load.
|
|
*
|
|
* The version string is the rendezvous datum between cooperating daemon and
|
|
* proxy processes: the daemon advertises its version in the hello line, and
|
|
* the proxy refuses to share IPC across a mismatch (falls back to direct
|
|
* mode). Keeping the resolution in one place avoids drift between the CLI
|
|
* `--version` output (which reads `package.json` directly) and the daemon
|
|
* handshake.
|
|
*
|
|
* Resolution strategy: read the bundled `package.json` two levels up from
|
|
* this file — same relative position whether we're loaded from `src/mcp/` or
|
|
* the `dist/mcp/` output, since `tsc` preserves the layout. If reading fails
|
|
* (e.g. the package was unpacked oddly), fall back to "0.0.0-unknown" — a
|
|
* sentinel that will never match a real version, so the proxy harmlessly
|
|
* falls back to direct mode.
