Public summary
GPT-6 Astra Max partial_post_task_metrics_snapshot_with_build_and_live_load ledger: 63m 51.9s (qualified snapshot span) wall-clock, 14.07M processed, and $20.53 Standard API-equivalent estimate from a qualified cumulative root-session snapshot, not a subscription invoice.

Recorded caveats
- The supplied token and cost totals are cumulative root-session snapshot values that include the beginning of the metrics follow-up; they are not a clean isolated generation-turn score.
- The raw parser did not recognize response_item user records, so the displayed wall-clock is a schema-aware recovered span rather than the parser's raw duration.
- Wall-clock includes tools and idle gaps, not model-only compute.
- Output tokens include hidden reasoning, visible prose/code, and tool-call JSON.
- Cache reads are discounted, so processed-token volume overstates cost.
- Supplied CDP input and FPS evidence is retained, but the archive operator only independently rebuilt and live-loaded the game; no fresh keyboard/mouse flight replay was run.
- Vinext's build IDs and chunk hashes are non-deterministic, so the successful clean build does not byte-match the submitted production tree.
- Blind visual evaluation remains outstanding.
Visible evidence gaps
- clean isolated generation-turn token and timing receipt
- fresh independent keyboard and mouse flight replay
- blind-evaluation record
