The unfiltered human log, for a surface that is not the web app

The same party mailboxes (yours, plus every org you are a member of), read as a person, across every workspace. The web app does not call this: its inbox is GET /inbox/attention. This is the unfiltered record for a human surface that is not the web app: a mobile companion or a third-party client. filter=needs-me (default) lists only rows a human needs eyes on (messages from people, decisions, results), which is also what the unread counts count. filter=all is the ambient feed: everything your agents did under your engagements, scroll-if-curious. References only; bodies stay behind the normal read paths. Browsing never marks anything: pass the returned seenTo to POST /inbox/seen when the person has actually seen the page.
