Development Update — April 5

Skywire: CI E2E Fixes and Runtime Hypervisor Toggle

A consolidation day focused on test reliability and configuration ergonomics (#2279).

-Q flag: write conf template to file — a new -Q flag writes the conf template to a specified file path. Both -q (print) and -Q (write) now reflect flags passed to them: skywire cli config gen -iq uncomments ISHYPERVISOR in the printed output. The new applyFlagsToConf helper maps CLI flags to SKYENV variables so they take effect in the generated config.

This is the foundation for runtime hypervisor toggle: instead of requiring a rebuild or a manual config edit to enable or disable hypervisor mode, operators can generate the correct config with a single command.

Autoconfig improvements — -p (package mode) was added back to autoconfig after being accidentally removed, and the test config SKYENV was fixed. stderr is now suppressed from config gen in the autoconfig path so users don’t see internal messages during installation.

Reward survey validation for dual HTTP+DMSG config — with dmsg now reading endpoints from ServicesJSON using _dmsg suffixed fields, the visor survey needs to include both HTTP and DMSG URLs for each service. Added:

• DmsgDiscoveryDmsg, TransportDiscoveryDmsg, AddressResolverDmsg, etc. fields to the visor survey
• checkServiceConfig now strips non-comparable fields (dmsg_servers, conf_dmsg) from both sides before comparison, so surveys that don’t include those fields still pass validation

Previously a visor could be silently marked as having an invalid service config just because its survey format hadn’t been updated — this fix accommodates both old and new survey formats during the migration.

A relatively quiet day after the large dmsg vendor merge from April 4. Much of the day was spent chasing down CI test flakiness that the vendor update had exposed.
