Common Response Envelope

Every route returns:

{
  "status": "success"
}

Field format and behavior:

Field	JSON type	Format	Presence rules
status	string	success or error	Always present
data	object/null	Route-specific data	Present only for some successful responses
code	integer/null	Error code	Typically 1 on status=error; usually omitted on success
message	string/null	Diagnostic message	Usually present on status=error; usually omitted on success

Parsing recommendation:

• Always parse by status first.
• Treat data as route-specific and optional.
• Do not rely on message text for business logic; use code and route context.
