# Requirements Snapshot: v1.48 Collaborator Memory And Continuity Maturity

## Completed Requirements

- ✓ `REQ-CPROF-01`: topic-scoped collaborator profiles are derived into
  `collaborator_profile.active.json|md`
- ✓ `REQ-CPROF-02`: runtime bundle, status, current-topic memory, and
  session-start artifacts surface collaborator-profile status, summary, and
  durable paths
- ✓ `REQ-TRAJ-01`: durable `research_trajectory.active.json|md` materializes
  recent trajectory continuity for the active topic
- ✓ `REQ-TRAJ-02`: current-topic memory, status, and session-start surfaces
  explain continuity in terms of recent trajectory
- ✓ `REQ-MODE-01`: learned route and lane preferences are projected into a
  durable `mode_learning.active.json|md` surface
- ✓ `REQ-MODE-02`: learned mode guidance is bounded, reviewable, and exposed
  through runtime surfaces instead of hidden heuristics
- ✓ `REQ-VERIFY-01`: the milestone closes with a non-mocked collaborator
  continuity acceptance path through production CLI surfaces

## Validation Summary

- production runtime/status/current-topic/session-start continuity surfaces
- isolated acceptance:
  `run_collaborator_continuity_acceptance.py --json`
- full test suite green
