devcontainer.json is the input
sshpod discovers .devcontainer/devcontainer.json in specification order and interprets it. The Dev Container specification is the compatibility target, not an sshpod-specific workspace format.
sshpodis early-stage software. Version 0.1.x implements a deliberately limited vertical slice — discover adevcontainer.json, create or start its container, report its status, and stop it. It does not implement the full Dev Container specification. The roadmap tracks what is verified as complete.
