/**
|
|
* Unit tests for PRAutoBlogger_Gen_History_Query.
|
|
*
|
|
* Tests cover:
|
|
* (1) get_run_io() extracts input_system and input_user from request_json.
|
|
* (2) get_run_io() sets output_pruned correctly for different meta_json states.
|
|
* (3) get_run_io() marks null output for log-only stages (no run_stages row).
|
|
* (4) get_page() returns empty result when wpdb is null.
|
|
*
|
|
* NOTE: PHP is unavailable in the sandbox. Structure self-verified before
|
|
* push (see PR description for grep + brace-count output).
