Because the runtime is itself spec-compliant, Go's lax matching only ever fabricated paths the runtime could never resolve, producing the ENOTDIR crash family and mounting/uploading files no import can reach.

 ## Notes
 
+- Any legacy Function name positional arguments are accepted and ignored. The command always
+ serves every discovered Function, matching the current Go behavior while preserving invocations
+ such as `supabase functions serve <Function name>`.
 - The hidden `--all` flag is still parsed but ignored; the native port always serves every discovered function, matching the Go command.
 - Each restart re-reads config, rebuilds per-function bind mounts, recreates the `supabase_edge_runtime_<project>` container, and best-effort reloads Kong afterwards.
 - The command creates or reuses Docker resources derived from the resolved project id:
