    "Native --print --mode json emits JSON event wrappers; score the first assistant text inside message_end, not the wrapper. Both first assistant texts match actual backend SSE content exactly. Raw event streams contain private runtime/model paths and remain private with hashes; public event streams are explicitly sanitized projections.",

Each original has one forward, zero denied retries, no callable tools, response tool calls or native tool-execution events. Default coding system prompt is replaced by the frozen event-row instruction.",

    "Backend SSE usage totals 377 prompt / 68 completion tokens. Pi separates 123 cached input tokens, reporting 254 uncached input plus 123 cacheRead. Its configured zero model prices do not measure total operating cost. Native 5.114s / 5.259s are total process wall clocks, not isolated inference latency.",

Recorder preserves request and buffered response entity bytes with regenerated HTTP framing; no real-time chunk latency claim.
