Performance intelligence

• added a unified run timeline for process identity, focus, PresentMon telemetry, system pressure, settings snapshots, contamination signals, and protocol provenance
• added stable-segment metrics, causal A/B and A/B/A comparison, next-best-test selection, and differential file/registry learning for more reliable conclusions

Detection and advice

• expanded engine, install-marker, process, settings-file, registry, and Steam metadata coverage, with confidence-aware evidence fusion instead of single-signal guesses
• improved settings cache invalidation and snapshot enrichment so recommendations use the values that were actually observed for the current game and run
• restricted automatic optimization to one certified, reversible change at a time, with exact readback verification, rollback metadata, and measurable retest criteria

Overlay, capture, and reliability

• kept GameUP Overlay external, read-only, and injection-free, including in multiplayer and anti-cheat environments; injection-only safety gates do not block the normal overlay path
• upgraded PresentMon result processing with provenance, focus/contamination filtering, richer diagnostics, stable-window analysis, and replay/fuzz regression coverage
