# Phase 75 Summary

Status: implemented on `main`

## Goal

Make research-trajectory continuity explicit across topic status, current-topic
memory, and session-start restart surfaces.

## What Landed

- new durable helper:
  `research/knowledge-hub/knowledge_hub/research_trajectory_support.py`
- topic-scoped `research_trajectory.active.json|md` now materializes from
  trajectory collaborator-memory rows
- `topic_status`, current-topic memory, and session-start artifacts now expose
  trajectory status, summary, and durable paths
- continuity now names related and recently active adjacent topics instead of
  leaving recent trajectory inside raw memory rows

## Outcome

Phase `75` is complete.
`v1.48` now has durable collaborator-profile and trajectory continuity
surfaces, ready for Phase `76`.
