# Baseline Compare / Drift Target Image Sidecar

## Not Implementation Truth

This target image is visual direction only. It is not runtime implementation truth, not a product capability claim, and not a substitute for later repo, RBAC, data, audit, and browser verification.

## Transformation Table

| Current state | Target direction |
| --- | --- |
| Browser fixture returned 404 for the compare route. | Target is bounded to route-verified compare/readiness guidance. |
| Raw diff risk can dominate first read. | Drift impact and evidence gaps lead before raw diff. |
| Assignment, freshness, and operation truth need separation. | Baseline, compare freshness, evidence gap, and run proof are distinct. |

## Repo-Truth Classification

| Element in target image | Classification | Implementation note |
| --- | --- | --- |
| Baseline compare route | repo-verified | Route exists, fixture blocked. |
| BaselineProfile and OperationRun concepts | repo-verified | Existing models. |
| Drift impact clusters | plausible-existing | Must map to compare result data. |
| Evidence gap scoring | foundation-only | Product direction only. |
| Exception workflow from drawer | conceptual-future-state | Separate spec required. |

## Conceptual Elements Requiring Verification

- Baseline assignment data source
- Compare freshness calculation
- Drift impact grouping
- Evidence gap display and customer-safe wording

## Implementation Notes

Later implementation should put impact before raw diff and keep compare actions authorized, audited, and OperationRun-backed.

## Do Not Implement Blindly

Do not invent drift scores, evidence scores, or exception workflows from this visual.
