`dsh-system-prompt` accepts `includeHarnessIdentity: false`, while `dsh-agent-spine-demo` forwards that setting and accepts `toolBash: false`. A deployment can therefore own an exact persona and replace the spine's native Bash without duplicate prompt or tool registrations. Existing defaults remain unchanged.
Both plugins are included in the Python runtime closure. The persistent Bash closure also includes the PTY service/local backend and the sandbox services required by that backend. Because `node-pty` executes a native `spawn-helper`, each packaged runtime executable ships with an architecture-matched `-spawn-helper` sibling. A pinned `node-pty` patch resolves that sibling only when present (or when `DSH_NODE_PTY_SPAWN_HELPER` explicitly selects one), preserving upstream lookup in ordinary Node runs; the executable and runtime-wheel builders fail before publication when the helper is absent, mismatched, or not executable.

A pinned `node-pty` patch resolves that sibling only when present, preserving upstream lookup in ordinary Node runs. The explicit `DSH_NODE_PTY_SPAWN_HELPER` override remains for a current external consumer that supplies a non-sibling helper. The executable and runtime-wheel builders inspect ELF or thin Mach-O headers and fail before publication when the helper is absent, mismatched, or not executable.
