+# File Info v1 Design
+
+## 1. Doel
+File info voegt nu waarde toe omdat de huidige UI sterk gericht is op navigatie en acties, maar nog weinig context geeft over het geselecteerde item zelf. Een compacte read-only infomodal helpt bij controle vóór rename/move/delete, bij het onderscheiden van vergelijkbare items, en bij snelle inspectie van een directory of bestand zonder de workspace te verlaten.
+
+Dit past goed binnen de dual-pane workflow zolang het een lichte, tijdelijke overlay blijft en geen extra paneel of blijvende schermruimte vraagt.
+
+## 2. Startgedrag
+Aanbevolen v1-gedrag:
+- Mac: `Cmd+Enter`
+- Windows/Linux: `Ctrl+Enter`
+- Alleen actief bij exact 1 geselecteerd item
+- Geen extra zichtbare knop in topbar of functiebalk in v1
+
+Reden:
+- De interface blijft rustig
+- De feature blijft beschikbaar voor power users
+- Het voorkomt nieuwe visuele drukte in de bestaande workspace
+
+Latere uitbreiding:
+- Een functiebalkknop zoals `Info` of `F9` kan later logisch zijn, maar hoort niet in deze slice
+
+## 3. Scope
+In scope voor v1:
+- Exact 1 file
+- Exact 1 directory
+- Read-only modal
+- Geen acties vanuit de modal
+- Geen thumbnails
+- Geen preview, edit of playback in deze modal
+
+Niet in scope:
+- Multi-select info
+- Bestandsinhoud tonen
+- Directory tree analyse
+- Checksums/hashes
+- ACL/permissions-editor
+
+## 4. Minimale informatievelden
+Aanbevolen minimale velden in v1:
+- `name`
+- `path`
+- `type`
+- `size`
+- `modified`
+- `root`
+- `extension` voor files waar zinvol
+- `content_type` voor files waar zinvol
+- `owner`
+- `group`
+
+Toelichting:
+- `name`, `path`, `type`, `modified` en `root` zijn bijna altijd nuttig
+- `size` is nuttig voor files; voor directories alleen als veilig/goedkoop beschikbaar
+- `extension` is nuttig voor file-context
+- `content_type` is nuttig als lichte afgeleide metadata, niet als zware contentanalyse
+- `owner/group` is nuttig voor troubleshooting op mounted storage
+
+## 5. Directory-info
+Veilige v1-richting voor directories:
+- Toon:
+  - naam
+  - pad
+  - type = directory
+  - modified time
+  - root/context
+  - owner/group indien beschikbaar
+- Toon niet standaard:
+  - recursieve grootte
+  - totale child count via diepe scan
+
+Aanbeveling:
+- Geen recursieve directorygrootte in v1
+- Geen child count tenzij die goedkoop via directe listing kan worden opgehaald en duidelijk als shallow count wordt gelabeld
+
+Motivatie:
+- Grote trees kunnen duur zijn
+- Dit verhoogt regressierisico en latentie zonder kernwaarde voor v1
+
+## 6. Backend-impact
+Aanbevolen backendrichting:
+- Nieuw read-only endpoint, bijvoorbeeld:
+  - `GET /api/files/info?path=...`
+
+Herbruik bestaande infrastructuur:
+- `path_guard` voor alle padvalidatie
+- bestaande whitelist/root containment
+- bestaande not-found/type/security foutmapping
+- bestaande filesystem-adapter voor `stat`-achtige metadata
+
+Veiligheidsmodel:
+- Alleen metadata lezen
+- Geen filesystem-mutatie
+- Geen directory traversal buiten whitelist
+- Geen volgen van escapes buiten toegestane roots
+
+Waarschijnlijk benodigde backendvelden in response:
+- `name`
+- `path`
+- `type`
+- `size`
+- `modified`
+- `root`
+- `extension`
+- `content_type`
+- `owner`
+- `group`
+
+## 7. Frontend-impact
+Aanbevolen UI-richting:
+- Aparte info-modal
+- Geen hergebruik van de tekst-viewer of edit-modal
+- Zelfde lichte modalstructuur als bestaande modals, voor consistentie
+
+Gedrag:
+- Open via `Cmd+Enter` of `Ctrl+Enter`
+- Sluiten via `X` en `Escape`
+- Terwijl modal open is, geen paneelkeyboardnavigatie
+- Geen interferentie met gewone `Enter`
+
+Samenwerking met bestaande openflows:
+- Gewoon `Enter` blijft directory openen en video openen waar nu al afgesproken
+- `Cmd/Ctrl+Enter` wordt exclusief voor File Info
+- Daardoor blijft bestaand open-gedrag intact
+
+## 8. Regressierisico
+Belangrijkste risico's:
+- Keyboardconflict met bestaand `Enter`
+- Focusconflict met bestaande modals
+- Onbedoeld openen bij multi-select of lege selectie
+- Verwarring met bestaande view/edit/video flows
+
+Laag-risico aanpak:
+- Alleen reageren bij exact 1 selectie
+- Alleen `Cmd/Ctrl+Enter`, niet gewone `Enter`
+- Eigen modal-open check in de globale keyboard handler
+- Geen wijziging aan bestaande browse/selectie/open-directory logica
+
+## 9. Teststrategie
+Backend golden tests:
+- file info success
+- directory info success
+- path not found
+- traversal blocked
+- invalid root alias
+- file/directory response shape
+
+UI smoke/regressietests:
+- info-modal container aanwezig
+- keyboard wiring voor `Cmd/Ctrl+Enter` aanwezig
+- geen extra zichtbare knop toegevoegd in functiebalk/topbar
+
+Handmatige validatie:
+- Exact 1 file geselecteerd -> info opent
+- Exact 1 directory geselecteerd -> info opent
+- Multi-select -> niets doen
+- Lege selectie -> niets doen
+- `Escape` sluit modal
+- Gewone `Enter` blijft bestaande open-semantiek houden
+
+## 10. Aanbeveling
+Aanbevolen v1-richting met laag regressierisico:
+- Nieuw read-only endpoint `GET /api/files/info?path=...`
+- Aparte compacte info-modal
+- Alleen openen via `Cmd+Enter` op Mac en `Ctrl+Enter` op Windows/Linux
+- Alleen bij exact 1 geselecteerd item
+- Directory-info beperkt houden tot goedkope metadata
+- Geen zichtbare extra knop in deze fase
+
+Dit levert een bruikbare infofunctie op zonder de huidige dual-pane workflow, keyboardflow of bestaande modals onnodig te verstoren.
