# softcopy-proof-check

## Purpose

Create ownership evidence checklists and missing-proof reports.

## Triggers

- Proof or ownership review is required
- `development_mode` is known or needs checklist generation

## Non-triggers

- Generic drafting
- Repository scan without filing context

## Required outputs

- `softcopy/outputs/proof_check/ownership_evidence.candidate.yaml`
- `softcopy/outputs/proof_check/proof_checklist.md`
- `softcopy/outputs/proof_check/missing_proofs.md`

## Hard rules

- Use `development_mode`, never `ownership_mode`
- Distinguish required vs optional documents
- Do not overwrite an existing approved `softcopy/ownership_evidence.yaml`

## Workflow summary

1. Read confirmed or candidate development mode.
2. Generate proof checklist.
3. Mark missing and provided documents separately.
