Build run_with_feedback that wraps subprocess.run, captures stdout, stderr, exit code, and duration, truncates output deterministically, and appends a JSONL record the next turn and the verification gate both read.
- Three demo commands to exercise the runner: one success, one failure, one slow
- Token budget: deterministic head plus tail with a
...truncated N lines...marker

- Telemetry pipelines (OTel, Langfuse). Feedback is for the next turn; telemetry is for the operator.
- Redaction passes and rotation policy. Lesson exercise prompts cover those.
