# Review both sides of a state-transition guard

Illustrative planning brief; no automatic product import.

Synthetic planning case: A manual state model permits ready→accepted only when receiving approval is present. The only rehearsal starts ready with approval present; it reaches accepted.

## Decision

The allowed transition is exercised, but its false-guard boundary is not. Add a ready-state case with approval absent whose expected outcome is remaining ready with a recorded rejection.

## Owned work

- Declare the guard and rejection state
  - Owner role: Model owner
  - Acceptance evidence: Approval presence is the sole toy guard; rejection preserves ready.
- Create both origin-state fixtures
  - Owner role: Rehearsal owner
  - Acceptance evidence: The false-guard case genuinely starts ready without approval.
- Inspect state after rejected transition
  - Owner role: Reviewer
  - Acceptance evidence: Evidence includes rejection and unchanged state, not just a displayed error.

## Workflow

1. Declare the guard and rejection state. Check: Approval presence is the sole toy guard; rejection preserves ready.
2. Create both origin-state fixtures. Check: The false-guard case genuinely starts ready without approval.
3. Inspect state after rejected transition. Check: Evidence includes rejection and unchanged state, not just a displayed error.

## Judgment

Approval is an invented model flag. The page does not assert native permissions, enforcement or authorization features.


## Filled manual planning note

The allowed transition is exercised, but its false-guard boundary is not. Add a ready-state case with approval absent whose expected outcome is remaining ready with a recorded rejection. The same origin state and requested transition have two supplied guard values. One successful true-guard case cannot establish the false-guard rejection or its unchanged state. Approval is an invented model flag. The page does not assert native permissions, enforcement or authorization features.


## Working artifact

- True guard / Start ready; approval present / Expect accepted
- False guard / Start ready; approval absent / Expect rejection and ready
- State preservation / Inspect resulting state explicitly / No silent intermediate acceptance


## Workflow questions

### Does an invalid-combination test prove this guard?

Only if it exercises this starting state, guard and expected unchanged result; a role/operation grid alone does not.

### Can I infer rejection from no accepted output?

No. Verify the resulting state and rejection evidence explicitly.

## 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

Starting state | Approval guard | Expected result | Current evidence
--- | --- | --- | ---
Ready | Present | Accepted | One matching rehearsal
Ready | Absent | Remain ready; reject transition | Unexercised

### Reasoning

The same origin state and requested transition have two supplied guard values. One successful true-guard case cannot establish the false-guard rejection or its unchanged state.

### Bounded result

The allowed transition is exercised, but its false-guard boundary is not. Add a ready-state case with approval absent whose expected outcome is remaining ready with a recorded rejection.

### Distinct decision

This checks both truth values of a state-transition guard and the rejected transition’s preserved state.

### Limits

Approval is an invented model flag. The page does not assert native permissions, enforcement or authorization features.
