IC currently relies on sfdx-project.json to establish the namespace for scratch orgs in module configuration. Our team develops against a repository that includes sfdx-project.json with a namespace value that is used to spin up orgs with a tool that is external to IC. Our development model, however, requires us to use non-namespaced orgs for development. That produces a mismatch between the namespaced org that IC expects and the connected non-namespaced org, resulting in errors with symbol resolution and test execution.
If IC could query the actual scratch org to determine the namespace, that would resolve our issue.
