To wit:

• Bind POST handler.
• Fix behavior for since_per_partition/offsets for unspecified partitions. The current /articlesdirect does what the documentation says: fetch only "live". However, /articles fetches from "earliest". We are going to amend the documentation so /articlesdirect also needs to change.

Find any other differences and fix them, /articles and /articlesdirect should be equivalent. There might also be differences in filters for default values in fields, they should be identified and we should decide which version we prefer.

Acceptance criteria:

• Table of comparisons with any current differences between /articles and /articlesdirect as part of this ticket
• User observable differences
• inform the team if we need a follow up ticket for implementation

To consider
This is a precursor for end to end testing (groundwork)
