## Summary
- integrate the current `platform-dev` branch into `dev`
- bring the latest platform work from the integration branch into the main development branch
- include the recent findings lifecycle backfill removal slice together with the already accumulated `platform-dev` changes
## Scope
- source branch: `platform-dev`
- target branch: `dev`
- branch role: integration PR, not a single-feature PR
## Validation
- branch state reviewed before PR creation
- `platform-dev` is ahead of `dev` with the expected integration history
- this PR intentionally carries the accumulated `platform-dev` commits into `dev`
## Notes
- this is the correct merge direction for the current workflow, where feature branches land in `platform-dev` first and `platform-dev` is then merged into `dev`
- after merging, `platform-dev` can be recreated fresh from `dev` as usual
