[0.1.1] - 2026-08-10

ExecutionPlane.Process.Transport.Surface.capabilities/1 guarded its with clause on is_atom/1 alone. nil is an atom, so a missing surface_kind satisfied the guard and was forwarded to the adapter registry, which reported {:unsupported_surface_kind, nil} instead of the {:invalid_execution_surface, opts} the function defines for that case. The same shape made the function's own nil -> clause unreachable.
The guest bridge frame decoder read length from outside a bitstring match without pinning it. That works on current Elixir, is a hard error on newer releases, and reads ambiguously against Kernel.length/1.

Dead code the compiler had proved unreachable: two chunk || "" fallbacks where decode_bytes/1 always returns a binary on that path, a normalize_env_value/1 boolean clause already covered by the atom clause above it, and a keyword_list?/1 catch-all whose callers all guard on is_list/1.
