+Use ConfigKit's optional-search behavior when automatic discovery finds no file:
+continue with embedded defaults, underlays, and explicit CLI settings, then
+validate what the requested command needs. Require sufficient configuration for
+the operation, not the existence of a main configuration file.

+Resource inspection can work without a main file. Processing can run when its
+required selections and inputs are otherwise supplied through supported
+mechanisms. Report missing command-specific settings clearly; do not invent an
+implicit model or profile selection to make incomplete execution settings pass.
+Inspection must accurately show that no main file was selected.

+Define filesystem context explicitly where overlays or relative resource inputs
+need it; do not infer a base from unsuccessful search candidates. Preserve the

-**Recommendation:** use ConfigKit's optional-search behavior: continue with

-This follows the native absent-main lifecycle and supports lightweight command
-invocations. It requires clear errors for missing command-specific inputs and
-inspection that accurately shows that no main file was selected.

-**Alternative:** require a discovered configuration file for configuration-dependent
-commands, while keeping help/version independent. This gives deployments a
-mandatory configuration anchor, but rejects otherwise sufficient defaults and
-CLI settings and adds a requirement without an identified domain need. Explicit
-file errors remain terminal under either choice.
