# Investigations

This directory holds research reports, experiments, comparisons, and draft workflow proposals for Video Workbench.

Investigation files are not stable operating rules by themselves. Accepted conclusions must be promoted into `README.md`, `VIDEO_WORKBENCH.md`, `docs/`, or project templates before they become durable workflow rules.

Notes:

- The first prompt-quality investigation over-weighted character and MV identity scenarios. It is retained as historical evidence.
- The V2 prompt-quality investigation is the accepted basis for shifting final image prompt ownership to Codex.
- The text-to-image / image-to-image execution-boundary investigation records local workflow policy only. It does not validate final image quality.
- Any historical `makeup-still/` directory recommendation inside old investigation files is superseded by the current `visual-system/` rule.
