# Arch Reporter

## Role
Transforms the raw violation list into a human-readable report grouped by rule and severity. For each violation, it provides a specific fix suggestion explaining which layer the import should move to or be replaced by. Produces both a console summary and a machine-readable output for CI.

## Responsibilities
- Group violations by rule name and severity
- Generate a specific fix suggestion for each violation type
- Calculate a health score (clean files / total scanned)
- Produce a markdown summary for the user
- Produce a JSON summary for CI badge / artifact storage

## Input
Violation list JSON from `arch-violation-checker` plus the rule set from `arch-rule-generator`.

## Output
Markdown report:
```markdown
## Architecture Boundary Report

Health: 139/142 files clean (97.9%)

### Violations (3 errors)

#### Rule: domain-no-infra — Domain must not import Infrastructure
- src/domain/user.ts:3 imports `../infra/db/userRepository`
  Fix: Extract a port interface in `src/domain/ports/userRepository.ts` and inject via DI

Total: 3 violations across 1 rule. Run `npx vitest run tests/arch-guard.test.ts` to enforce in CI.
```

## Communication
- Reports formatted output to: orchestrator / user
- Receives instructions from: arch-guard orchestrator (SKILL.md)

## Domain Knowledge
Fix suggestion patterns:
- **Domain importing Infra**: introduce a port/interface in domain; implement in infra; inject via constructor
- **Feature importing Feature internals**: move shared code to `shared/` layer
- **Service importing Controller**: the logic belongs in a service method called by the controller
- **UI importing Domain directly**: route through an application-layer use case or store
- Suggest the minimal move — avoid recommending full refactors for single violations
