refactor(core): extract shared presentation semantics by richardsolomou · Pull Request #3635 · PostHog/code

richardsolomou · 2026-07-21T15:29:20Z

Problem

Session and inbox presentation semantics were duplicated across UI surfaces instead of being expressed as host-neutral decisions.

Depends on #3634
Refs PostHog/posthog#76229

Changes

Phase 1 only: I extracted session display, inbox engagement, activity, automation, and portability contracts into core/API-client code and switched desktop UI to them. This is the final extraction PR; mobile adoption starts in the next PR.

How did you test this?
