# Bridge review evidence after a workflow model changes

Illustrative planning brief; no automatic product import.

Synthetic planning case: Model v1 permits A→B and B→C. Model v2 retains A→B, removes B→C, and adds B→D and D→C. Existing passing traces all name v1.

## Decision

Retain applicable A→B evidence with its original version and inspect it against v2. The removed B→C route cannot prove either new v2 edge; plan B→D and D→C checks explicitly.

## Owned work

- Record both model identities
  - Owner role: Model owner
  - Acceptance evidence: The retained, removed and added edges are explicit.
- Check evidence applicability edge by edge
  - Owner role: Reviewer
  - Acceptance evidence: Same endpoint C is not substituted for proof of passing through D.
- Rehearse the changed route
  - Owner role: Delivery owner
  - Acceptance evidence: v2 traces include B→D→C with intermediate evidence.

## Workflow

1. Record both model identities. Check: The retained, removed and added edges are explicit.
2. Check evidence applicability edge by edge. Check: Same endpoint C is not substituted for proof of passing through D.
3. Rehearse the changed route. Check: v2 traces include B→D→C with intermediate evidence.

## Judgment

Model version tags identify invented contracts, not product release compatibility or complete proof of unchanged behavior.


## Filled manual planning note

Retain applicable A→B evidence with its original version and inspect it against v2. The removed B→C route cannot prove either new v2 edge; plan B→D and D→C checks explicitly. v2’s declared edge set has three edges. Only A→B is shared with v1. Old B→C success reaches the same C endpoint but does not traverse the new intermediate D or its outgoing edge. Model version tags identify invented contracts, not product release compatibility or complete proof of unchanged behavior.


## Working artifact

- Retained edge / A → B / Check old-proof applicability
- Removed edge / B → C / Preserve as historical evidence
- Added route / B → D → C / Assign two new transition checks


## Workflow questions

### Must every old result be discarded?

No. Relevant retained behavior may keep evidence after an applicability check.

### Is an unchanged final outcome enough?

No when the accepted model requires new intermediate behavior.

## Product connection

Use the owned checks and downloaded brief to discuss this planning decision alongside your TeamBoostAI tasks. Confirm available fields, roles and account features separately. The example is manual; it does not calculate live analytics, create work or run an experiment in the product.

Confirm account availability before adopting this manual outline.

## Original worked case

Synthetic records, manual planning only. No account import or live analytics.

### Inspect the invented case records

Edge | v1 status | v2 status | Evidence action
--- | --- | --- | ---
A → B | Allowed | Retained | Check applicability of old proof
B → C | Allowed | Removed | Historical only; not new-route proof
B → D | Absent | Added | New check
D → C | Absent | Added | New check

### Reasoning

v2’s declared edge set has three edges. Only A→B is shared with v1. Old B→C success reaches the same C endpoint but does not traverse the new intermediate D or its outgoing edge.

### Bounded result

Retain applicable A→B evidence with its original version and inspect it against v2. The removed B→C route cannot prove either new v2 edge; plan B→D and D→C checks explicitly.

### Distinct decision

The artifact bridges changed graph edges across versions rather than copying an acceptance label or updating documentation.

### Limits

Model version tags identify invented contracts, not product release compatibility or complete proof of unchanged behavior.
