# Spec

## Goal

- What problem does this change solve?
- What user or system outcome must become true?

## Scope

- In scope:
- Out of scope:

## Key Scenarios

Use these scenarios as the BDD outer loop. Each scenario should describe observable behavior, not implementation steps.

If a User Story exists, reference its scenario id or locator here instead of copying the full story into `spec.md` as a second truth source.

### Scenario 1

Given
- a clear starting state

When
- the actor performs the target action

Then
- the expected observable outcome happens

### Scenario 2

Given
- an important variant or edge condition

When
- the relevant action occurs

Then
- the system still behaves within the intended boundary

## Behavior Evidence

- Story scenario mapping:
- Scenario coverage:
- Expected evidence locator:
- Freshness rule:
- Execution ledger acceptance locator:
- `not_applicable` rationale, if this is not a behavior-bearing change:

## Exceptions And Boundaries

- Failure modes:
- Operational boundaries:
- Rollback or fallback expectations:

## Acceptance Criteria

- [ ] Target outcome is observable
- [ ] Key scenarios are covered
- [ ] Important boundary behavior is defined
- [ ] Validation evidence is identified
- [ ] Behavior evidence can be consumed by review, merge-ready, and closeout
