Decision Making (agent-native)
Rank contract changes and verify findings by impact on primary actor goals and invariants — output to decisions.md, sorted findings[], and fix.md sections.
Fix target classification
Before writing fix.md, set fix_target on each finding in run.json:
| Signal | fix_target |
|---|
| Missing UI, bug, invariant violation on live product, a11y on existing screen | product |
| Scope change, new workflow/invariant, defer feature, contract wrong | contract |
Default: product when fix_target is unset. Product fixes belong in fix.md → coding session. Contract items belong in fix.md → /lamina-design delta prompt only.
Decision filter
Does this finding change a specific design or implementation decision? If not, dig deeper or drop.
Impact × effort (verify findings)
| Impact | high | medium | low |
|---|
| Definition | Blocks workflow, invariant violation, primary actor stuck | Friction with workaround | Polish |
| Effort | high | medium | low |
|---|
| Definition | Cross-workflow contract change | Localized screen/scenario | Copy/label fix |
Sort: high impact + low effort first; then high impact + high effort. Record rationale in decisions.md.
Primary actor filter
When actors conflict:
- Does option serve primary persona goals completely?
- If no → deprioritize or cut; if yes → design fully for their scenario.
- Log trade-off in
decisions.md with rejected actor impact noted.
Used when reconciling parallel persona panel outputs.
Evidence weighting
| Source | Weight |
|---|
| Invariant probe failure on live product | highest |
| Actor walk blocker (repro steps) | high |
| Walkthrough/repo grounding | medium |
| Assumption in design | low — mark to-verify |
Never rank invented analytics above reproduced actor failures.
