ehoandClaude Opus 4.8 a828e604d1 docs(backlog): add Phase 8 — platform/DX/showcase (WP-37..46)
New phase from the 5-item analysis: linked showcase snippets + animations,
runnable scaffolding generators (pages/wizards/context/SSP), dependency graph +
declarative boundaries, PII hardening (branded Bsn VO + masked-value atom +
persisted no-PII audit) doubling as a privacy showcase, and Vitest coverage.
Goal: both a teaching showcase and a production starter template. Sequenced with
priorities + dependencies in the README.

WP-38 — Dependency graph + declarative boundaries

Status: todo Phase: 8 — platform/DX/showcase Priority: P1

Why

Bounded-context + atomic-layer boundaries are enforced only by hand-duplicated no-restricted-imports blocks in eslint.config.mjs — pass/fail, no graph, and brittle: the new-context skill literally says "grep the config and copy a block", and herregistratie is missing its explicit ban block (asymmetry). We want to see the dependencies AND enforce them from one declarative source.

Decisions

  • Step 1 — tool fork: dependency-cruiser (recommended: graph + CI rules on plain Angular) vs Sheriff (tag-based, DDD/atomic-native, weaker graph). Decide before building.
  • Encode context + layer rules once (contexts shared/auth/registratie/herregistratie/brief/beheer/ showcase; layers domain/application/infrastructure/contracts/ui); fix the herregistratie gap.
  • Keep ESLint for the intra-file rules it does better (domain↛@angular, ApiClient value-import confinement, no-explicit-any); migrate only the cross-module direction rules to the new tool.
  • Emit a graph the showcase/teaching can reuse (feeds WP-39).

Files

  • New: .dependency-cruiser.js (or sheriff.config.ts); npm run graph + validate script.
  • scripts/ci-local.sh + .github/workflows/ci.yml — add depcruise --validate (non-optional).
  • eslint.config.mjs — remove the migrated direction rules (keep the rest).
  • New doc docs/reference/architecture/dependencies.md; embed the graph in a Foundations page.
  • .claude/skills/new-context/SKILL.md — point at the single declarative source.

Acceptance criteria

  • One declarative config expresses all allowed context/layer edges; herregistratie included.
  • npm run graph produces an architecture graph (SVG/HTML); validate runs in npm run ci.
  • A deliberately-illegal import fails the validate step (proven, then reverted).
  • No loss of enforcement vs the old ESLint blocks; npm run ci green.
