  "sourceFinding": "prompt.ts initializes step=0, increments step before evaluating step>=agent.steps, and appends MAX_STEPS_PROMPT as assistant when last step. Frozen steps=1 therefore inserts the warning in the first model request. Both actual SSE responses contain that same text; backend reports only one completion token per case, so returned prefilled assistant text is not equivalent to newly generated token count. This configuration-confounded pilot does not assess default coding-agent quality. Original configuration, output and failure remain unchanged.",
