`claude --print --output-format json` reports its own failures (API error, usage limit, error_max_turns) as the result envelope on stdout and leaves stderr empty, so ask_pm()'s stderr-only message logged "claude exited 1: " with nothing after it, twice on 2026-10-31. describe_cli_failure() now logs the envelope's diagnostic fields plus stdout/stderr tails, redacted (sk-ant-, Bearer/token, URL userinfo). PM_DECISION_MAX_TURNS (default 1, unchanged) makes the max-turns remedy a ConfigMap change if the envelope turns out to say error_max_turns. Co-Authored-By: Claude Opus 5.5 <[email protected]>
