Add a "PII — maskeren & parsen" section to /concepts demonstrating the WP-40 pieces with FP + atomic design, framed for AVG art. 9 / data-minimisation: a live <app-masked-value> atom (masked BSN that reveals on click; real reveal is step-up + audited in behandel-scherm) and a live parseBsn elfproef parse. Both show the real linked source via the WP-39 snippet mechanism (new showcase regions in bsn.ts + pii.ts, registered in gen-snippets.mjs). Delivers WP-42's showcase demo; the persisted-audit half stays pending WP-41. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# WP-42 — Privacy & security showcase page
|
|
|
|
Status: partial — mask/parse showcase done; audit half pending WP-41
|
|
Phase: 8 — platform/DX/showcase
|
|
Priority: P2
|
|
Depends on: WP-40, WP-41
|
|
|
|
## Outcome (mask/parse half — done, on user request ahead of WP-41)
|
|
|
|
Added a "6 · PII — maskeren & parsen" section to `/concepts` demonstrating the WP-40 pieces with
|
|
FP + atomic design, framed for AVG art. 9 / data-minimisation: a live `<app-masked-value>` atom
|
|
(masked-by-default BSN that reveals on click; note points to the real step-up + audited reveal in
|
|
behandel-scherm) and a live `parseBsn` elfproef parse mirroring the postcode demo. Both show the
|
|
real linked source via the WP-39 snippet mechanism (`// #region showcase:parseBsn` in bsn.ts,
|
|
`showcase:mask` in pii.ts, registered in `gen-snippets.mjs` → `snippets.generated.ts`, drift-gated).
|
|
No i18n (showcase is Dutch-only teaching text). No behaviour change outside the showcase.
|
|
|
|
**Still pending (needs WP-41):** the "log PII / no-PII audit trail" half — visualizing the
|
|
persisted authz/reveal audit — plus an optional Foundations MDX writeup.
|
|
|
|
## Why
|
|
|
|
Once the reusable privacy pieces exist (WP-40 masked-value atom + pure maskers, WP-41 persisted
|
|
no-PII audit), showcase them as a teaching artifact: how to **mask** and **log** PII safely with FP
|
|
(pure functional core) + atomic design (the masked-value atom), tied to the existing reveal +
|
|
step-up + capability slice.
|
|
|
|
## Decisions
|
|
|
|
- A Foundations MDX + a small `showcase` demo (showcase context may read every context).
|
|
- Teach the principles explicitly: data-minimisation, PII out of logs, masked-by-default +
|
|
audited reveal, server as authority — framed for a Dutch register (AVG art. 9, BIO).
|
|
- Reuse WP-39's linked-snippet mechanism so the shown code can't drift.
|
|
|
|
## Files
|
|
|
|
- New `src/docs/privacy-security.mdx` (Foundations).
|
|
- New/extended `showcase` demo wiring `<app-masked-value>`, the pure maskers, and the reveal flow.
|
|
|
|
## Acceptance criteria
|
|
|
|
- [ ] Page demonstrates mask + no-PII logging with live components and linked (non-drifting) code.
|
|
- [ ] Explains the register rationale (AVG/BIO/data-minimisation) concisely.
|
|
- [ ] Storybook a11y green; `npm run ci` green.
