DOCA.6:3 - Forces
| Force | Tension |
| Immediate and later value | A candidate outside the current front can preserve a useful later option. |
| Preservation and cost | Saving a short account can be cheap; maintaining data access, expertise, equipment, or supplier availability may not be. |
| Paths and uncertainty | A path helps expose dependencies but can make an unqualified future appear inevitable. |
| Diversity and comparability | Opportunities can serve different contributions and horizons without sharing one meaningful score. |
| Lineage and change | Revisions need a recoverable basis without preserving every obsolete candidate as live. |
| Revisit and inertia | Retention needs an action-changing reason and a stop, not an indefinite promise to reconsider. |
