- sunset_scale_migration_test, lineup tests: call StrategyMigrator,
  where cloud moved the migration statics.
- agent_weapon_test: export/import through StrategyImportExportService,
  where cloud moved zip and file-drop handling.
- strategy_switch_side_test: open the strategy with loadFromHive (cloud's
  open path) and mock path_provider for its storage directory.
- strategy_page_session_provider_test: assert the hydrated lineup as a
  graph origin.
- text_widget_resilience_test: tap into edit mode first, since main's
  markdown text only mounts a TextField while editing; shorten the
  growth sample so it fits the harness column.

Assertions are unchanged except where they named removed API.
