# REQ-tv-p00002: Collaborative Requirement Review System

**Level**: PRD | **Status**: Draft | **Implements**: REQ-tv-p00001

## Assertions

A. The system SHALL support threaded comments anchored to specific positions within requirement text.

B. The system SHALL support status change workflows with approval gates for transitions between Draft, Active, and Deprecated states.

C. Comment positions SHALL survive content changes through hash-based drift detection and fallback resolution strategies.

D. Review data SHALL be stored in git branches following the `reviews/{package}/{user}` naming convention.

E. Review packages SHALL group related requirements for coordinated review workflows.

F. The system SHALL function offline with git-based synchronization when connectivity is available.

G. The system SHALL provide a Flask API server for real-time review operations.

H. The review UI SHALL integrate with the existing trace_view HTML output as a collapsible panel.

## Rationale

The collaborative review system enables teams to review requirements without modifying the source specification files. By using git branches and JSON storage, the system maintains full audit trails compatible with FDA 21 CFR Part 11 requirements. Position-anchored comments allow precise feedback that survives requirement edits through intelligent re-anchoring.

The package system supports sprint-based or topic-based review workflows, while the branch-per-user model enables offline work with eventual consistency through git merge operations.
