Erik 3ee8ec537a perf(diag): complete trustworthy Slice A capture tooling
Correct whole-frame GPU timestamps so they bracket only the accepted render transaction and associate delayed query results with the owning CPU frame. Add route-wide frame-history summaries, fixed-camera screenshot comparison, process counters, contention traces, a pinned Arwic workload, and credential-safe launch disclosure.

The reference hardware/display contract now keeps local and RDP populations separate and defines the screenshot and re-baseline rules needed by later prepared-content gates.

Performance reference configuration

The machine-readable contract is 2026-07-24-performance-reference-configuration.json. It fixes the reference CPU/GPU/driver/OS, graphical settings, routes, display paths, screenshot rule, and re-baseline policy used by the Modern Runtime Architecture plan.

Only the physical AMD display path is authoritative for frame-time, CPU, and GPU acceptance gates. Remote Desktop runs are intentionally retained as a separate diagnostic population: they validate the connected route, resource lifetime, allocation attribution, and major regressions, but the 32 Hz remote presentation path cannot establish maximum throughput.

The connected routes pin the client-only world-time override at noon. The dense-town route uses ACE's canonical Arwic point-of-interest arrival and a fixed six-second retail-input turn before its screenshot and checkpoint.

Screenshot comparison uses a per-channel tolerance of 2 and permits at most 0.1% differing unmasked pixels. Dynamic particles or similarly nondeterministic pixels require an explicit same-resolution alpha mask; a failure is not accepted by silently increasing the global tolerance.
