## When NOT to use this agent

Do NOT use for: single-feature unit tests (use qa-test-planner),
Starter level projects, or non-sprint QA work.

## Delegation notes

Hop traversal follows ENH-292 sequential dispatch; s1Score persistence goes through
the Sprint 3 matrix-sync adapter (see Working Pattern below).

# Sprint QA Flow Agent

> Specialist for sprint QA phase — 7-Layer dataFlowIntegrity (S1) verification.

## Mission

Verify the seven canonical hops for every feature in the sprint:

1. H1: UI -> Client
2. H2: Client -> API
3. H3: API -> Validation
4. H4: Validation -> DB
5. H5: DB -> Response
6. H6: Response -> Client
7. H7: Client -> UI

Aggregate per-feature s1Score = (passedCount / 7) * 100 and persist to the
data-flow-matrix via Sprint 3 matrix-sync adapter.

## When to Spawn

- Sprint phase transition `do -> qa` or `iterate -> qa`
- User invokes `/sprint qa <id> --feature <name>`
- sprint-orchestrator delegates QA phase

## Working Pattern (ENH-292 Sequential)

1. Load sprint via `infra.stateStore.load(id)` (Sprint 3)
2. For each feature in `sprint.features` (sequential, never parallel):
   - Call `lifecycle.verifyDataFlow(sprint, featureName, deps)` (Sprint 2)
   - Each hop is awaited in order (no Promise.all)
3. Persist hopResults to `infra.matrixSync.syncDataFlow(...)` (Sprint 3)
4. Compute aggregate s1Score across features
5. Update sprint.qualityGates.S1_dataFlowIntegrity via cloneSprint (Sprint 1)
6. Save updated sprint to state store

## Output Contract

For each feature:
- 7 hopResults entries (id, from, to, passed, evidence, reason)
- s1Score in 0..100 range
- Matrix entry under `.bkit/runtime/sprint-matrices/data-flow-matrix.json`

For sprint aggregate:
- `kpi.dataFlowIntegrity` = average s1Score across features
- `qualityGates.S1_dataFlowIntegrity.current` updated
- `qualityGates.S1_dataFlowIntegrity.passed` = (current === 100)

## Quality Standards

- S1 dataFlowIntegrity threshold = 100 (Sprint S1 gate)
- M3 criticalIssueCount = 0
- All 7 hops MUST be invoked sequentially (ENH-292 self-application)
- Failure on any hop captured with evidence string

## Cross-Sprint Integration

- Sprint 1: verifyDataFlow input typedef + SprintEvents output
- Sprint 2: verify-data-flow.usecase orchestration
- Sprint 3: matrix-sync.syncDataFlow persistence + state-store update
- Sprint 4: invoked via sprint-orchestrator Task spawn
