- Gateway-host op regel 18 en in Configuration: maos.dedyn.io -> ipfs.maos.dedyn.io
  (config.ts gatewayUrl() en de CSP in next.config.ts)
- Upload-flow (quick + crypto): proxyIPFS -> handleLocalUpload() -> .data/files/
  met auto-pin, i.p.v. Kubo /api/v0/add
- Nieuwe sectie 'Lokale opslag (.data/) en de gateway-route': endpoint-tabel voor
  pins/files, opslaglayout, het feit dat een lokale CID geen echte IPFS-CID is,
  en GET /ipfs/<cid> inclusief content-type, Content-Disposition en foutpaden
- src/lib/api.ts (bestaat niet meer) -> src/lib/api/ als module-tabel; het
  achtergebleven api.ts.bak benoemd
- route.ts: ~320 -> 121 regels, met verwijzing naar proxy-ipfs.ts en write-auth.ts
- mapToKuboAPI-lijst: dode mappings /pins en /files/upload weg, met de reden
- Pages-tabel en API-flow noemden pins/files nog als Kubo-afhankelijk
- Schema en het bestaande write-auth-gedeelte ongemoeid
- Warnt expliciet dat .data/ nog niet in .gitignore staat

+`pins`, `pins/<cid>` en `files/upload` hebben **geen** mapping: `proxyIPFS()`
+onderschept die paden vóór de Kubo-vertaling en serveert ze lokaal (zie onder).
+Voeg hier dus geen `pin/*`- of `add`-tak toe zonder `proxyIPFS()` en
+`isMutatingRequest()` mee te wijzigen.
+
+---
+
+## Lokale opslag (`.data/`) en de gateway-route
+
+### Pins en files gaan niet naar Kubo
+
+`proxyIPFS()` (`src/app/api/[...path]/proxy-ipfs.ts`) behandelt `pins`,
+`pins/<cid>` en `files/*` volledig zelf. Deze paden bereiken de Kubo RPC nooit,
+ongeacht of `KUBO_API_URL` wel of niet gezet is — de lokale opslag werkt dus
+ook zonder Kubo.
+
+| Portal-endpoint | Handler | Effect |
+|---|---|---|
+| `GET /api/pins` | `handleLocalPins` | Leest `.data/pins.json` → Kubo-vorm `{ Keys: { <cid>: { Type } } }` |
+| `POST /api/pins` | `handleLocalPins` | `localAddPin(cid, name, size)` |
+| `DELETE /api/pins/<cid>` | `handleLocalPins` | `localRemovePin(cid)` |
+| `POST /api/files/upload` | `handleLocalUpload` | `localSaveFile()` + auto-pin |
+| `GET /api/files` | `handleLocalListFiles` | `localListFiles()` |
+| `GET /api/files/<cid>` | `handleLocalGetFile` | Serveert `.data/files/<cid>-<naam>` als attachment |
+| `DELETE /api/files/<cid>` | `handleLocalDeleteFile` | `localDeleteFile(cid)` |
+
+### Opslaglayout
+
+| Pad | Inhoud |
+|---|---|
+| `.data/pins.json` | `Record<cid, { cid, name, size, created }>` — `src/lib/local-pins.ts` |
+| `.data/files/<cid>-<naam>` | De ruwe bestandsbytes — `src/lib/local-files.ts` |
+| `.data/files.json` | `Record<cid, { cid, name, size, modified, path }>` |
+
+De "CID" van een lokaal opgeslagen bestand is geen echte IPFS-CID maar
+`"Qm" + sha256(inhoud).slice(0, 44)` (`generateCid()` in `local-files.ts`).
+Content is daarmee adresseerbaar binnen deze portal, maar niet op een
+ander IPFS-netwerk. `.data/` is runtime-state: het ontstaat bij het eerst
+uploaden en moet in een deploy een volume zijn, want een rebuild wist hem anders
+leeg. ⚠️ `.data/` staat op dit moment **niet** in `.gitignore` — voeg die regel
+toe voordat er per ongeluk runtime-state gecommit wordt.
+
+### `GET /ipfs/<cid>` — de gateway-route
+
+`src/app/ipfs/[cid]/route.ts` is de gateway die deze share-links bedient.
+`gatewayLink()` in `src/lib/helpers.ts` bouwt alle deel-links als
+`<NEXT_PUBLIC_GATEWAY_URL>/ipfs/<cid>`, wat precies dit pad volgt.
+
+| Request | Gedrag |
+|---|---|
+| `GET /ipfs/<cid>` | Valideert het CID-prefix (`Qm`/`bafy`/`bafk`), daarna `POST <KUBO_API_URL>/api/v0/cat?arg=<cid>`, met Basic auth als `KUBO_BASIC_AUTH` gezet is |
+| `GET /ipfs/<cid>?filename=…` | Zet `Content-Disposition: inline; filename="…"` |
+
+De response draagt het `Content-Type` dat Kubo terugstuurt, met
+`application/octet-stream` als fallback als upstream niets bruikbaars stuurt.
+De body wordt volledig in geheugen geladen (`arrayBuffer()`) — voor grote
+bestanden is dat nog geen streaming. Foutpaden: `400` (ongeldig CID), `501`
+(zonder `KUBO_API_URL`), de Kubo-status zelf, of `502` bij een netwerkfout.
+
+---
+
+## Write authentication
+
+Muterende `/api/*`-endpoints eisen een token; lees-endpoints blijven publiek.
+Ingang: `authorizeWrite()` in `src/app/api/[...path]/write-auth.ts`, aangeroepen
+vanuit `POST` en `DELETE` in `route.ts`. De waarde komt uit
+`ipfsWriteToken()` in `src/lib/config.ts` (env `IPFS_WRITE_TOKEN`).
+
+| Endpoint | Methode | Write-gate |
+|---|---|---|
+| `/api/add` | POST | ✅ |
+| `/api/files/upload` | POST | ✅ |
+| `/api/files/<cid>` | DELETE | ✅ |
+| `/api/pins` | POST | ✅ |
+| `/api/pins/<cid>` | DELETE | ✅ |
+| `/api/ipns/publish`, `/api/ipns/keys/gen/<naam>` | POST | ✅ |
+| `/api/users/<naam>` | DELETE | ✅ |
+| `/api/explorer/{ls,cat,stat,resolve}/<cid>` | POST | ❌ lees-only |
+| `/api/pins`, `/api/files`, `/api/explorer/*`, `/api/health` | GET | ❌ publiek |
+| `/ipfs/<cid>` (gateway) | GET | ❌ publiek |
+| `/api/users` (registratie) | POST | ❌ open — eigen auth van Python-backend |
+
+**Toegang tot een mutatie — één van beide volstaat:**
+
+1. `Authorization: Bearer $IPFS_WRITE_TOKEN` (MAOS → portal, server-to-server).
+   Vergelijking is constant-time via SHA-256 digests (`crypto.timingSafeEqual`).
+2. De bestaande portalsessie-JWT cookie `ipfs-portal-session` — identieke
+   verificatie als `src/middleware.ts`. Zónder dit pad zouden de eigen
+   upload-/pin-pagina's van de portal kapotgaan.
+
+Geen van beide → `401` (geen `Authorization`-header) of `403` (header aanwezig,
+verkeerde waarde), met `WWW-Authenticate: Bearer`.
+
+**`IPFS_WRITE_TOKEN` niet geconfigureerd** → writes blijven **open** met een
+eenmalige luide waarschuwing in de log. `src/lib/config.ts` heeft geen
+"required in production"-patroon (alleen defaults, in tegenstelling tot
+`JWT_SECRET` in `auth-server.ts`), en een harde fail zou elke nog niet
+geprovisioneerde deploy direct breken — vandaar bewust fail-open + waarschuwing.
+
+**Besluit — publieke lees-endpoints**: `GET /api/pins` en `GET /api/files`
+blijven anoniem toegankelijk. Ze lekken alleen metadata (CID's, namen, maten);
+content is sowieso publiek via de gateway. Ze achter de sessie zetten zou de
+publieke explorer (pin-badges) én MAOS' pin-status/inventory-reads breken — die
+sturen vandaag geen `Authorization`-header op GET. Zodra MAOS ook GET's met
+Bearer verstuurt kan dit alsnog achter de gate.
+
+**Rest-risico**: `POST /api/users` (registratie én admin-aanmaak, zelfde
+endpoint) blijft open — een registrant heeft noch token noch sessie. De
+Python-backend is daar de autoriteit (`X-Admin-Key` + doorgestuurd
+`X-Session-Token`).
