# RD-03 — Move the portal home into its own `overzicht` context

Status: done
Source: PLAN.md Phase 0

## Why

The dashboard is the portal home, but it lives inside `registratie` — a context that
`.dependency-cruiser.ssp.js` declares as `registratie: []`, permitted to import no other
context. Three concrete symptoms:

- Its six sections span four concerns: registratie data (3), aanvragen (1), cross-context
  action links to `/herregistratie` `/intake` `/brief` `/concepts` (1), and admin links to
  `/beheer/*` (1).
- The cross-context coupling is **invisible to the linter**, because
  `wat-wilt-u-doen.section.ts` links by route _string_. `npm run dep:check` passes and gives
  false assurance on exactly this file.
- `beheer-links.section.ts:6` imports `ADMIN_LINKS` from `../../../shell/nav.config` — a
  context reaching into the app frame.

Splitting the dashboard into sections is what makes this fixable at all. That is the
refactor's first real payoff.

## Read first

- `apps/ssp/src/app/registratie/ui/dashboard.page.ts` (42 lines, pure composition)
- `apps/ssp/src/app/registratie/ui/dashboard/` — the six sections
- `.dependency-cruiser.ssp.js` — the `CONTEXT_ALLOWED` map (5 lines)
- `libs/shared/src/layout/site-header/nav-config.ts` — the `HEADER_ADMIN_LINKS` token
- `libs/shared/src/layout/site-header/site-header.component.ts:99` — how to inject it
- `apps/ssp/src/app/app.config.ts:72` — where `ADMIN_LINKS` is already provided to the token
- `plopfile.mjs`, the `context` generator
- CLAUDE.md decision 1 (DDD contexts and layers)

## Decisions (pre-made, don't relitigate)

1. **New context name: `overzicht`.** Dutch, per CLAUDE.md ("domain contexts are Dutch"), and
   it matches the page's own title, "Mijn overzicht".

2. **Only the page and the two _navigation_ sections move.** These three:
   - `dashboard.page.ts` → `overzicht/ui/overzicht.page.ts` (class `OverzichtPage`, selector
     `app-overzicht-page`)
   - `dashboard/wat-wilt-u-doen.section.ts` → `overzicht/ui/wat-wilt-u-doen.section.ts`
   - `dashboard/beheer-links.section.ts` → `overzicht/ui/beheer-links.section.ts`

3. **The four data sections STAY in `registratie/ui/dashboard/`** — `mijn-aanvragen`,
   `wat-moet-ik-regelen`, `mijn-registratie`, `specialismen`. They render registratie data and
   belong beside `BigProfileStore`/`AanvragenStore`. Do not move them, and do not move their
   three story files.

4. **Declare `overzicht: ['registratie']`** in `.dependency-cruiser.ssp.js` — the second
   sanctioned cross-feature edge, mirroring `herregistratie: ['registratie']`. The generator
   inserts `overzicht: []`; you must change it.

5. **`beheer-links.section.ts` injects `HEADER_ADMIN_LINKS`**, exactly as
   `site-header.component.ts:99` does. Drop the `shell/nav.config` import entirely.
   `app.config.ts:72` already provides `ADMIN_LINKS` to that token, and the `AdminLink` doc
   comment already says it is "Consumed by the site header's admin nav AND (per app) a
   dashboard's own Beheer section". The direct import was always the anomaly.

6. **KEEP the route at `/dashboard`.** Four e2e specs assert it (`e2e/smoke.spec.ts:18`,
   `e2e/brief-v2.spec.ts:33`, `e2e/error-state.spec.ts:16,18`), and it is a user-visible URL.
   Only the `loadComponent` import path and the class name change. Add a one-line comment in
   `app.routes.ts` saying the path stays `dashboard` deliberately while the context is
   `overzicht`, so the mismatch reads as a decision and not an oversight.

7. **Use `npm run gen:context`, then correct three things.** The generator gets the folders,
   the `@overzicht/*` tsconfig alias, and the dep-cruiser entry right. It gets three things
   wrong for this case:
   - it writes `overzicht: []` → change to `['registratie']` (decision 4)
   - it scaffolds a **new** `overzicht.page.ts` from a template → delete it, the real page is
     the moved `dashboard.page.ts`
   - it adds a **new** `path: 'overzicht'` route → delete that block, and instead repoint the
     existing `dashboard` route (decision 6)

8. **Delete the empty layer folders the generator creates.** `overzicht` has no `domain/`,
   `application/`, `infrastructure/` or `contracts/` — it is composition only. Remove those
   four `.gitkeep` directories rather than keeping scaffolding for work that does not exist.

9. **The page keeps its 8 imports.** CLAUDE.md has no import-count rule; one `import` per
   rendered section is exactly right. Do not introduce an `OVERZICHT_SECTIONS` const to get
   the number down — that trades a self-documenting array for an indirection, and this repo
   deliberately has no barrels.

## Files

Move (use `git mv` so the rename is visible in review):

| From                                                                   | To                                                         |
| ---------------------------------------------------------------------- | ---------------------------------------------------------- |
| `apps/ssp/src/app/registratie/ui/dashboard.page.ts`                    | `apps/ssp/src/app/overzicht/ui/overzicht.page.ts`          |
| `apps/ssp/src/app/registratie/ui/dashboard/wat-wilt-u-doen.section.ts` | `apps/ssp/src/app/overzicht/ui/wat-wilt-u-doen.section.ts` |
| `apps/ssp/src/app/registratie/ui/dashboard/beheer-links.section.ts`    | `apps/ssp/src/app/overzicht/ui/beheer-links.section.ts`    |

Edit: `apps/ssp/tsconfig.json` (alias), `.dependency-cruiser.ssp.js` (edge),
`apps/ssp/src/app/app.routes.ts` (import path + class + comment),
`apps/ssp/src/app/overzicht/ui/beheer-links.section.ts` (token),
`apps/ssp/src/app/overzicht/ui/overzicht.page.ts` (class, selector, section import paths).

## Steps

1. Run `npm run gen:context` and answer `overzicht`.
2. Delete the generated `overzicht/ui/overzicht.page.ts` and the four empty layer folders.
3. Delete the generated `path: 'overzicht'` route block from `app.routes.ts`.
4. Change the generated `overzicht: []` to `overzicht: ['registratie']`.
5. `git mv` the three files per the table above.
6. Rename the page's class to `OverzichtPage` and its selector to `app-overzicht-page`; fix
   its six section import paths (four now via `@registratie/ui/dashboard/…`, two local).
7. Repoint the existing `dashboard` route to `@overzicht/ui/overzicht.page` / `OverzichtPage`
   and add the comment from decision 6.
8. Rewrite `beheer-links.section.ts` to inject `HEADER_ADMIN_LINKS` per decision 5.
9. Update this ticket's `Status:` to `done` and the README's RD-03 row to `done`.
10. Commit all of it together.

## Acceptance criteria

```bash
npm run dep:check     # exits 0 — proves overzicht: ['registratie'] is accepted
npm run ci            # exits 0
```

Then prove the boundary is real, not decorative:

```bash
# Add a temporary import of a herregistratie file to overzicht/ui/overzicht.page.ts.
# `npm run dep:check` MUST fail (overzicht may reach registratie only). Then revert.
```

And prove the section still renders for an admin:

```bash
grep -n "HEADER_ADMIN_LINKS" apps/ssp/src/app/overzicht/ui/beheer-links.section.ts   # present
grep -rn "shell/nav.config" apps/ssp/src/app/overzicht/                              # no match
```

## Verification

`npm run ci`. No story or `.mdx` file moves in this ticket — the three section stories stay
in `registratie` — so `--full` is not strictly required. Run it once anyway, because this is
a structural move and Storybook globs the app's stories by path.

Manual check, since e2e is not in the local GREEN one-liner: `npm start`, open
`http://localhost:4200/dashboard`, confirm all six sections render, then `?role=admin` and
confirm the Beheer section appears (and is absent without it).

## Out of scope

- Renaming the route to `/overzicht`. It needs a redirect and touches four e2e specs.
  Recorded in PLAN.md as deliberately out of scope.
- Moving the four data sections (decision 3).
- Story titles — that is RD-04.
- Turning `wat-wilt-u-doen`'s action list into a token beside `NAV_ITEMS`. PLAN.md Phase 0
  step 6 lists it as a "consider"; leave it for now, since route strings on a landing page
  are legitimate once the page lives in a context whose job is cross-context linking.

## Risks

- **The generator's three wrong outputs** (decision 7). If you skip the corrections,
  `dep:check` still passes with the boundary silently missing — the exact failure mode
  `plopfile.mjs`'s own comment warns about for `create-frontend.mjs`.
- **`messages.xlf` / `messages.en.xlf` carry `<context context-type="sourcefile">` paths**
  that these moves make stale. Nothing checks them and `$localize` ids are the identity, so
  `ng build --localize` stays green. Do **not** hand-edit the xlf files to chase paths.
- **Do not change any `$localize` id.** Every id in the three moved files stays byte
  identical; only the file's location changes. A changed id needs a new English `<target>` or
  the localize gate fails.
- **`git mv`, not delete-and-create**, or the review loses the rename and the diff looks like
  300 new lines.
