Developers can change behaviour with filters. A few of the most useful:

Filter	Purpose
`updoc_key_pages`	Change the key pages. Hosts are enforced afterwards
`updoc_owned_data`	Change the options, option patterns and tables an item owns
`updoc_probe_allowed_hosts`	Hosts a probe may contact. Add subsite hosts here
`updoc_check_seconds`	Deadline of one after-check (default 120)
`updoc_settle_seconds`	Settle pause (default 5, capped at 5)
`updoc_log_path`	The PHP error log path to read
`updoc_observer_inline`	Whether an observed update is checked in the request that installed it (default true)

// Allow checks to visit a subsite on its own domain.
add_filter( 'updoc_probe_allowed_hosts', function ( $hosts ) {
	$hosts[] = 'shop.example.com';
	return $hosts;
} );

Cron hooks are updoc_run_step, updoc_scheduler (hourly) and updoc_maintenance (twice daily). Actions updoc_proposal_created, updoc_proposal_executed, updoc_run_outcome and updoc_run_finished let other code react to runs.
