orisys-sdk-perf-plan.md moved to D:\orisys_ws\docs\performance\ as part of the 2026-09-27 workspace cleanup. docs/filters.md and examples/filters/README.md now name the new location; the _perf/ measurement scripts they also cited are deleted (the document keeps every measured number). Also ignore .scratch/, the new per-task scratch directory (see D:\orisys_ws\AGENTS.md).
