Add bench/ — a 4-category × easy/medium/hard task matrix (shell, code, git,
multi) and a runner that drives the live TUI over tmux and grades each task by
a `podman exec` verify snippet (exit 0 == PASS), never by the model's
self-reported summary (which the weak CPU model fabricates). Tasks run in the
agent's real cwd with bare filenames so the suite measures task completion, not
the model's absolute-path discipline. Completion is detected off the viewport-
independent `is thinking…` footer (the TUI is full-screen, so capture-pane
scrollback is not chat history).
First baseline (qwen2.5:3b): 2/12 PASS, high variance. Surfaces the next
harness-addressable improvements — `<native>` tag leakage and bare
tool-call-as-text — now measurable against this suite. Findings doc updated.

Replace the overloaded "text + no tool call = done" terminator that made the
weak CPU model stall mid-task or give up after a failing command. Termination
is now a structural `DONE:` text sentinel; a text-only turn is resolved by an
output-aware verdict (DONE: marker / unresolved non-zero exit / no action /
filler language) and re-prompted with an exit-code-aware nudge, bounded by
MAX_NUDGES on top of max_turns. On exhaustion the summary is honest rather than
echoing the model's false "run successfully" — it reports when no tool ran or a
command exited non-zero. Live-validated on qwen2.5:3b: the multi-step stall is
fixed (proj3 completes end-to-end, ground-truth confirmed); the nudge fires on
a 126; residual give-up is model-bound. 23 offline unit assertions pass.

Live 3B-vs-7B command-entry results, observed failure modes (early stall,
give-up-on-error, tool hallucination), Goose/opencode loop-termination
research, and the output-aware dynamic-nudge-loop design to implement.
