trellis-zero-to-mvp

Create a Trellis MVP task tree from a full requirements document. Use when Codex receives a product brief, requirements document, PRD, zero-to-MVP request, large capability-building request, or partially implemented project and must do read-only analysis, assign stable REQ/AC IDs, build full requirement and MVP coverage matrices, lock project contracts, identify existing implementation evidence, use progressive batch and sub-agent planning to form a complete MVP parent/child task tree, draft PRD/design/implementation artifacts, and create Trellis tasks only after user confirmation; do not write application code.
