# Phase 74 Summary

Status: implemented on `main`

## Goal

Open `v1.48` by making collaborator-profile continuity explicit across runtime
bundle, status, session-start, and current-topic memory.

## What Landed

- topic-scoped collaborator-profile artifacts are now normalized through the
  runtime bundle
- `topic_status`, `topic_next`, and `refresh_runtime_context` now surface
  collaborator profile directly
- `current_topic.json|md` now carries collaborator-profile status, summary, and
  durable paths
- session-start artifacts now include collaborator-profile paths
- runtime-bundle schema now exposes a stable top-level `collaborator_profile`
  contract

## Outcome

Phase `74` is complete.
`v1.48` is active on a verified collaborator-profile continuity baseline.
