step / failure / output(13 PRs) reflects ongoing investment in guardrails and reliability patterns across the agentic workflow stack.Sentiment reflects tech debt language: The negative lean (-0.085) is consistent with historical patterns where fix/error/failure terminology depresses polarity scores despite representing healthy engineering hygiene.
