# `workspaces.files.write`

Write a file into the hosted sandbox (≤1 MiB; scratch only — store state flows through mozaik push/proposals).

- **method + path**: `PUT /v1/workspaces/{ws}/file`
- **TR label**: Sandbox dosyası yazıldı
- **auth**: authenticated · scope gates: any of `admin`, `sandbox:use` — “Sandbox kullanımı için sandbox:use yetkisi gerekli”
- **agentPolicy**: `workspace` — writes confined to the caller's own draft workspace or staging — every token kind executes it directly.
- **effects**: `provider`, `db`
- **idempotency**: server — the platform derives the key
- **wraps**: — (no command inside)
