ehoandClaude Sonnet 5 e7156c5132 feat(WP-67): merge behandelportal into this repo as a monorepo
Restructures into apps/ssp + apps/behandelportal (two Angular projects)
plus libs/shared + libs/beheer (cross-app libraries), replacing WP-61's
separate sibling repo. That split had already produced real drift: a
hand-vendored copy of the backend's OpenAPI doc, a shared/ui+layout tree
forked and silently diverging (7 files), and beheer + the styles.scss
token bridge duplicated byte-for-byte across both repos.

- git mv the SSP's src/app/* into apps/ssp/; fold shared/, beheer/,
  environments/, the Storybook docs/*.mdx, and styles.scss into
  libs/shared + libs/beheer (all confirmed identical between the two
  repos before merging). auth stays deliberately duplicated per
  ADR-0002 (actor-specific, expected to diverge) - amended there.
- One generated API client (libs/shared), no more vendored swagger.json.
- .dependency-cruiser split into a base factory + one config per app,
  and Storybook into .storybook-ssp/.storybook-behandelportal - both
  forced by the @auth/* alias resolving to different directories per app.
- SiteHeaderComponent/ShellComponent gained HEADER_NAV_ITEMS/
  HEADER_ADMIN_LINKS/DEBUG_PANEL injection tokens so each app supplies
  its own nav/admin-links/dev-panel instead of one being hardcoded.
- CLAUDE.md, ARCHITECTURE.md, dependencies.md, and ADR-0002 updated;
  WP-67 backlog entry documents the full decision trail.

npm run ci green (lint, dep:check x2, 360 tests across ssp/
behandelportal/shared/beheer, both localized builds, backend tests,
snippet + api-client drift); both dev servers, both Storybook
instances, and docker compose verified working.

The old sibling repo (/home/eho/repos/behandelportal) is left
untouched, not deleted.

Dependencies & boundaries

How the app's bounded-context and atomic-layer boundaries are declared, enforced, and visualized (WP-38, generalized for the two-app monorepo by WP-67). One declarative source — .dependency-cruiser.base.js (a rule factory) plus one thin .dependency-cruiser.<app>.js per app — both guards the edges and draws the graph, replacing the per-context no-restricted-imports blocks that previously had to be hand-copied (and that had left herregistratie uncovered). Each app is cruised separately, against its own tsconfig.json: a single merged tsconfig can't resolve both apps' @auth/* alias at once (each points at a different physical directory), so there is no single global config file.

The rules (single source: .dependency-cruiser.base.js)

Bounded-context direction — dependencies point inward; every app context may use libs/shared and libs/beheer, nothing imports showcase:

Context (apps/ssp) May import
auth libs/shared, libs/beheer
registratie libs/shared, libs/beheer
herregistratie registratie, libs/shared, libs/beheer
brief libs/shared, libs/beheer
showcase everything in apps/ssp (sanctioned teaching page)
Context (apps/behandelportal) May import
auth libs/shared, libs/beheer
behandeling libs/shared, libs/beheer

libs/shared is the base (no feature context, no libs/beheer — that direction is forbidden too, so shared never grows a dependency on a peer library). libs/beheer is a real bounded context (admin/stamdata), used identically by both apps — it may depend on libs/shared, never the reverse. An app may not import the other app's source directly.

Atomic-layer rules: domain/ is framework-free (no Angular); contracts/ import nothing (pure wire DTOs, ADR-0001); ui/ + layout/ never import infrastructure/ directly (reach data through an application store/command — type-only DTO imports are fine); the generated ApiClient is a value only inside infrastructure/ (+ libs/shared/src/upload). Plus no circular dependencies. These apply uniformly across an app's tree and both libraries — no debug-state exception anymore (WP-67 moved the dev panel component out of libs/shared into apps/ssp since it's genuinely SSP-specific, coupled to BigProfileStore; the shared ShellComponent hosts whichever app-provided component the DEBUG_PANEL injection token supplies, or none).

See the graph

npm run dep:graph      # regenerates docs/reference/architecture/dependency-graph.md (mermaid) — one diagram per app

dependency-graph.md is the generated, committed view — contexts × atomic layers, edges are real imports. It renders on the git host; regenerate + commit after a structural change.

Enforce

npm run dep:check      # runs both apps' configs; fails on any forbidden edge; part of `npm run ci` and CI

A violation prints the offending from → to and the rule name. dep:check runs in the local gate (scripts/ci-local.sh) and the frontend CI job.

What still lives in ESLint

Only the non-dependency rules: @typescript-eslint/no-explicit-any and the angular-eslint template accessibility bundle (see eslint.config.mjs, scoped to {apps,libs}/**). Everything about who may import whom is in dependency-cruiser.

Adding a context

Add one context entry to the relevant app's object literal in .dependency-cruiser.ssp.js (or .dependency-cruiser.behandelportal.js) — passed straight into the shared buildConfig factory in .dependency-cruiser.base.js (and the tsconfig path alias + lazy route) — no more hand-copying ESLint blocks. The new-context skill / gen:context (plopfile.mjs, ssp-only today) covers the full checklist.
