Introduce the framed guest_channel_transport with shared deadlines and
std::jthread ownership, metadata-only retired-schema quarantine with
fail-closed integrity, stateless frozen-catalog validators with
capability pinned to zero, and the generic local-service proxy with
descriptor-pinned endpoints, alias-only guest sockets, audit-gated
delivery, and a Linux managed runtime capability derived only from a
registry-bound operational factory. Sage vocabulary is confined to
src/adapters/sage.
Model and PTY cannot self-report pass or failure. Glove now runs
each refinement-eval-v1 session through a declarative evaluator that
checks bounded fixture assertions (termination cause, exit code, max
latency, required and forbidden transcript literals) against audited
resource events, then binds the evaluated outcome inside the
authenticated receipt digest. Capability advances to version 1 with
the evaluator landed.
