Reuse the exact selected advertised descriptor for SDK output validation instead of compiling the entire cached catalog for every fresh parity-test client. Retain actual catalog discovery, schema validation, and all result assertions under the existing worker heap limit.
Send shell pm uninstall --user 0 through the shared quoted command boundary. Align tool guidance and Evidence limitations with the selected request scope while preserving device refusal diagnostics.
Validation: two provider controls failed before the fix and pass afterward; three public CLI/MCP scenarios capture exact arguments and equivalent success facts; nineteen command/SDK contract checks, check:fast and docs:check pass. No real device, multi-user data preservation, vendor/APEX behavior or performance measurement. Refs #4673.
