Request coverage

Request	Evidence condition	Outcome
NVIDIA recipe with slight modifications	Pinned source, exact launch, explicit delta	r2 configuration; upstream inference controls retained
Controlled A/B against current r11	Fresh controls and matched independent checks	Initial context baseline18/18 versus candidate17/18; native results
Tools, JSON, vision and synthetic agent tasks	Independent deterministic checks	Both passed applicable checks; repository-scale coding remains untested
Retry/debug the failed case and investigate configuration	Preserve original failure; predeclared repeats and conditional single-variable arm	Unchanged r2 full replay18/18; failed case3/3 follow-ups. Diagnostic did not reproduce the miss; no configuration cause or repair established. MTP-off condition not met
Preserve working deployment	Exact identity/config hashes and authenticated route	Final restoration verified original r11 and direct/routed checks2/2 each
Promotion	Separate authorization and complete qualification	Not authorized or performed

This closed scout and diagnostic does not provide a candidate performance ranking, sustained-concurrency qualification, four simultaneous327K requests, repository-scale coding score or endurance result. The initial failure remains failed. Subsequent passes are reported separately and do not establish a general failure probability or prove any causal component.
