The Rijkshuisstijl restyle (7a582ae) trimmed the dashboard action-card grid and
dropped the card linking to /intake, orphaning the branching herregistratie intake
questionnaire (reachable only by typing the URL; the breadcrumb still expected it).
Restore the action card (localized). The route, page and branching wizard were
intact — only the entry point was missing.

Implement-now:
- G1: keep PII out of persistent storage — never persist BSN (only `naam`);
move both wizard drafts (address/email, work data) localStorage → sessionStorage
so they clear on tab close.
- G2: validate storage reads before trusting the cast — shape/tag guard in every
restore() (mirrors the parse* HTTP boundary); corrupt/foreign shape → start fresh.
- G3: already satisfied (debug-state redacts via mask.ts).
Show-the-seam (hook + doc, not fully built):
- G4: problemFieldErrors() maps a server validation envelope (ASP.NET
ValidationProblemDetails `errors`) to the field-keyed map the wizards already
render; returns {} until the backend sends it. +spec.
- G5: documented the retry/backoff seam at the adapter GET loader; reads may
retry, mutating submits never do.
Out of scope (named): unsaved-changes warning (persistence prevents data loss),
real auth/tokens, axe-core in CI.
Gate green: lint, check:tokens, build, test 79/79.

Wrap every user-facing Dutch string in Angular's first-party i18n — `i18n`/
`i18n-<attr>` in templates, `$localize` in TS (value-objects, machines, commands,
label constants, shared-component defaults). Source locale stays nl; a second
locale is now a translation file, not a code change.
- M3: ~145 strings localized with stable @@ ids across registratie,
herregistratie, auth, shared/ui, shared/layout. Skipped: showcase, debug-state,
scenario interceptor, generated client, specs/stories, raw status enum tags,
internal parse* diagnostics.
- M4: single shared JA_NEE (localized labels) in radio-group; both wizard copies
removed.
Gate green: lint, check:tokens, build, test 77/77.

- H1: tasksFromProfile takes the server's eligibleForHerregistratie decision
instead of recomputing isHerregistratieEligible — the FE renders the rule,
doesn't own it (ADR-0001). Policy reference impl kept for tests.
- M1: one shared runSubmit(fn, fallback) wrapper; the 4 submit-* commands keep
only their payload mapping. +spec.
- M2: whenTag() kernel helper removes 10 repeated `as Extract<U,{tag}>` casts
across the wizard/form components.
M4 (shared JA_NEE) folded into the upcoming i18n pass (clean dedup needs
$localize labels to sit in shared without breaking the English-shared-UI rule).
L1 already resolved by the restyle commit.

Domain reference data already lives in the backend (per ADR-0001); the only
residual "move" was ~90 inlined Dutch UI strings with no i18n layer.
- Wire @angular/localize ($localize) — Angular first-party, no third-party lib
- Pin the pattern on shared/ui/async: Dutch fallbacks → language-agnostic
input()s with localizable $localize defaults (English-shared-UI rule)
- CLAUDE.md: drop i18n (now in scope) + stale "real backend"/"OpenAPI codegen"
(both already shipped); document the $localize convention
Bulk string sweep deferred to Step 2 to avoid touching ~36 files twice.

Chrome: two-tier Rijksoverheid header (white brand bar + lint-blue
breadcrumb bar, route-driven), dark multi-column footer, white page
surface. Session shown via a shared SESSION_PORT token (keeps shared/
free of the auth context).
Overview ("Mijn overzicht") rebuilt to the NL Design System #392 pattern:
side-nav + "Wat moet ik regelen" task list (derived) + "Mijn registratie"
cards. New shared components: card, task-list, side-nav; pure
tasksFromProfile (+spec).
Wizards: grey form panel, connected numbered stepper, form-field
"(verplicht)" markers + styled description/error, full-width inputs.
Propagated to login, detail, change-request, address-fields.
Bug fixes:
- wizard-shell: add FormsModule so NgForm intercepts submit (wizards now
advance; no native GET leaking choices into the URL).
- wizard-shell: error-summary links focus the field instead of navigating
(a fragment href resolved against <base href="/"> reloaded to "/" and
bounced to login).
- wizard-shell: error-summary focus only on the rising edge, so typing
while errors are shown no longer scrolls the page up.

Move the authoritative business rules off the frontend into a real backend,
realising the BFF-lite + decision-DTO design (ADR-0001) that until now lived
only in static mock JSON.
Backend (backend/):
- ASP.NET Core (.NET 10) minimal API, contract-first, Swagger UI at /swagger.
- DDD Domain/ rules layer: profession derivation + applicable policy questions
(DiplomaRules), herregistratie eligibility + reason (HerregistratieRule),
scholing threshold (IntakePolicy), submit rejections + reference generation
(SubmissionRules). In-memory seeded data, ProblemDetails (RFC 7807) errors.
- 27 xUnit tests: rule units + endpoint integration incl. BRP no-address and
DUO not-found fallbacks and 422 submit paths.
Frontend (only infrastructure/ + contracts/ change, as the architecture promised):
- NSwag-generated typed client (api-client.ts), routed through Angular HttpClient
via a small fetch adapter so the ?scenario= interceptor still applies.
- GET adapters use resource({ loader: client.x }); submit commands call the client
and map ProblemDetails -> err. The hardcoded uren==0 / manual-diploma rules are
deleted (now server-side). Domain, stores, UI and format validators unchanged.
- Deleted the now-dead public/mock/*.json.
Tooling/docs:
- npm start proxies /api -> backend; npm run gen:api regenerates the client;
docker compose up runs both (bind mounts use :z for SELinux/Fedora).
- backend/README.md walkthrough: adding a policy question is a one-file backend
change, no FE change, no client regen. Updated CLAUDE.md + ARCHITECTURE.md.

A floating, read-only panel that renders the current root-store state
(SessionStore + BigProfileStore) live via the json pipe. Whole thing is
gated by isDevMode() so it never renders or ships in production.
- Observer only — no new store/library/state pattern (PRD prime directive).
- BigProfileStore resolved lazily on first open; its httpResources fetch
eagerly on construction, so we avoid a personal-data fetch on pages that
don't use it.
- bsn masked before render; no persistence/logging/network in the feature.
- maskBsn has a unit spec; UI exercised via a Devtools Storybook story,
per repo convention (no TestBed component tests).

A progressive teaching guide (docs/fp-tea-atomic-design.md): FP fundamentals,
The Elm Architecture, and atomic design, taught Elm-then-this-app with the real
store/machine/value-object code, plus four recipes and a glossary. It owns the
teaching arc and cross-references ARCHITECTURE.md/ADR-0001 rather than duplicating
them. Documents reality where the PRD diverged (no state-debug-view feature; per-
wizard stores; reduce vs update naming) and flags the absent debug view as an open
question. Adds pointer links from ARCHITECTURE.md and CLAUDE.md.

The editable address block (straat/postcode/woonplaats) was hand-built inline in
two places — the registratie wizard and the change-request form. Factor it into one
pure presentational organism (values in, errors in, per-field change out) grouped in
a fieldset/legend, and adopt it in both. Behaviour, validation and state flow are
unchanged: the wizard still dispatches SetField (flipping adresHerkomst on edit) and
the change-request form still parses the postcode on submit. Storybook entry added;
other field clusters left inline by design (single-use or genuinely divergent).

Checkpoint of in-progress work: the registration wizard (address prefill,
DUO diploma lookup, policy questions), decision-DTO contracts, parse-don't-

- radio-group: the Utrecht radio paints its dot only with the
`utrecht-radio-button--checked` class (not the native :checked); we set
[checked] but not the class, so a selected radio looked empty. Bind the class
too. The intake step-1 choice now visibly selects.
- data-row: drop the border-block-end on the last row (:host:last-child) so a
summary ends cleanly instead of showing a trailing empty row (visible in the
concepts discriminated-unions card).

A second wizard demonstrating a BRANCHING flow: the visible steps are derived
from the answers by a pure `visibleSteps` function rather than stored, so
answering "buiten Nederland gewerkt? -> ja" or reporting few hours adds steps
and the progress denominator changes live. Same Elm-style store + RemoteData
patterns as the fixed wizard; answers persist to localStorage.
- intake.machine.ts: IntakeState union + Answers + visibleSteps + pure reduce (+spec)
- intake-wizard organism, intake.page, submit-intake command
- new radio-group atom (ControlValueAccessor) in shared/ui
- /intake route + dashboard link + concepts showcase section
- tighten Aantekening.type to a 'Specialisme' | 'Aantekening' union
- README + ARCHITECTURE updated
Verified live end-to-end (branches add steps 4->5->6, review, submit) with no
console errors; build, unit tests, and Storybook all green.

Step 1 was a single field, making the wizard feel thin. Add "Aantal jaren
werkzaam" beside "Gewerkte uren" on the same step (no new step): Draft/Valid
gain `jaren`, `next` validates both step-1 fields before advancing, and
`validate` parses it for the submitted payload. Verified live: an empty jaren
blocks advancing with an inline error.

Walking through the running app surfaced two issues:
- login-form's `submit` output collided with the native DOM `submit` event
bubbling to <app-login-form>, so login() also fired with an Event (not the
BSN string) — "bsn.trim is not a function". Renamed the output to `submitted`
(matching the other forms).
- The static mock herregistratie deadline (2027-09-01) sat outside the 12-month
eligibility window, so the wizard was correctly hidden. Moved it to 2027-03-01
so "verloopt binnenkort" is true and the flow is demoable.

Plain-language walkthrough of the bounded-context layering and the state
management (RemoteData, the Elm-style store, combining services, optimistic
updates, value objects), with a glossary — aimed at a junior with no functional
programming background.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Reorganise from atomic-design-only folders into bounded contexts
(auth / registratie / herregistratie) over a shared kernel, each split into
domain / application / infrastructure / ui layers. Dependencies point inward;
the domain layer is framework-free. Path aliases (@shared/@auth/@registratie/
@herregistratie) make import direction explicit.
State management (Elm-style, native TS, no new deps):
- shared/application/store.ts — createStore(init, update): pure reducer + signal
- shared/application/remote-data.ts — add map/map2/map3/andThen combinators so
several services fold into one RemoteData; <app-async> gains an [rd] input
- registratie/application/big-profile.store.ts — root singleton combining the
BIG-register and BRP services via map2 into one state; holds the optimistic
herregistratie flag shared with the dashboard
- herregistratie: machine gains a WizardMsg union + pure reduce; submit is a
command that calls infra and dispatches the result, with optimistic update +
rollback against the shared store
- auth: SessionStore + DigiD adapter + functional route guard; login establishes
the session, protected routes use canActivate
Rich domain: registration.policy.ts (statusColor/label, herregistratie
eligibility, invariants); BigNummer/Postcode/Uren value objects with smart
constructors. status-badge is now domain-free (colour/label inputs).
Specs for the reducer, RemoteData combinators, and eligibility policy.

A teaching page pairing each pattern's impossible-state-permitting "before"
with the "after" the type system enforces: discriminated unions, the
RemoteData fold, parse-don't-validate (live), and the wizard state machine.
Composition-only — no new atoms. Linked from the dashboard.

Model the multi-step form as one tagged union: step/errors exist only while
Editing, and Submitting/Submitted/Failed carry a parsed Valid payload. So
"submitting while a field is invalid" and "success screen with errors set"
are unrepresentable by construction.
Pure transitions (next/back/submit/resolve) with a spec covering the key
invariants; illegal events are no-ops. The page becomes pure composition.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Add smart constructors parsePostcode/parseUren returning Result<string, Brand>.
The constructor is the only way to mint a Postcode/Uren, so a validated value
is a distinct type from a raw string.
change-request-form now emits a ChangeRequest carrying a parsed Postcode, and
its field errors come straight from the parser's Result — no parallel "is it
valid" flag that can drift out of sync with the value.

Each status variant now owns its own data: only Geregistreerd carries a
herregistratieDatum; Geschorst/Doorgehaald carry their own dates + reason.
A struck-off registration can no longer hold a future herregistratie date —
that impossible combination is gone from the type.
- status-badge keys color off the tag via a switch + assertNever
- registration-summary renders only the rows a variant's data supports
- registration.json nests the status; stories cover all three variants

Introduce RemoteData<E,T> (Loading | Empty | Failure | Success) plus
fromResource and an exhaustive foldRemote. The data lives ON the state,
so "loaded without value" or "error with stale value" are unrepresentable.
AsyncComponent now derives a single rd() and pulls value/error out via the
fold instead of a loose State string. Public API (resource/isEmpty inputs,
the four slot directives, the ASYNC array) is unchanged, so the dashboard,
detail page, and async stories need no edits.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The shared foundation for the "make impossible states impossible" work:
- assertNever for compile-time exhaustiveness in union switches
- Result<E,T> + ok/err constructors (plain objects, no classes)
- Brand<T,B> for nominal types
No runtime dependency — this is the whole "library".

- Fix full-bleed header/footer (align-items:stretch + block hosts; centered
content column via shared --app-content-max).
- New templates/page-shell (back-link + heading + intro + content, narrow mode);
all pages refactored to compose it.
- Async state management with native httpResource + <app-async> wrapper that
renders exactly one of loading/empty/error/loaded (impossible states
unrepresentable); delayed spinner + skeleton atoms for slow/fast connections.
- Scenario interceptor (?scenario=slow|loading|empty|error) to demo every state.
- Storybook: spinner/skeleton/page-shell/async-states stories.
- README rewritten as a guide (atomic design, reuse benefits, state handling).
