Editorial context
Confidence: low
Likely practical consequence — participants will need to verify order settings and minimum order size requirements before the changes are deployed. The next observable signal will be the publication of exact new specifications or a notice of the actual implementation of the update. Substantial uncertainty remains due to the lack of concrete values and independent verification.
