## Goal

${epic.goal}

${epic.value}

## Problem or opportunity

${epic.problem}

## Constraints

${epic.constraints.map((item) => `- ${item}`).join('\n')}

## Features

No child Features have been defined or approved. Feature discovery must preserve this Epic boundary and requires a separate human **Approved for Solution** decision before Architecture solution work begins.

## Original source

${sourceList(epic)}

### Legacy implementation evidence

The approved catalogue was mined from legacy revision \`${epic.legacy_revision}\`.

# Review the approved Epic catalogue

These ten Epics define the documented product boundary mined from materially implemented legacy behavior. \`3DARCH-EP-1\` owns the engineering foundation; every remaining Epic describes a user experience or usage outcome.

Planned-only capabilities—including VR entry, whiteboards, extra Archwiz domains, exports, and undo—remain outside this catalogue until separately evidenced and approved.

# Review the product roadmap baseline

The current roadmap records the approved Epic catalogue without inventing sequence, dates, Feature scope, or delivery commitments. All Epics remain in \`IN_BACKLOG\`; future horizon and dependency decisions require separate evidence and human approval.
