+## How the local-file connector works
+
+`local.html` reads a dropped or chosen file's bytes once, right there in the tab — nothing is uploaded. It identifies the KDBX format from the file's first 8 bytes via the shared `packages/router` package (the same format-detection logic every chooser page uses, so which implementation reads a given format is decided in exactly one place), then embeds the matching implementation (currently only `0x67.html`) in an iframe and hands it the bytes it already read, over the same same-origin message protocol (`packages/embed-protocol`) the cloud connectors use. There is no second file picker: the file is never re-selected on the embedded app's own upload screen, because the app never shows one when opened this way. A file that's recognized but has no implementation yet (KeePass 1.x `.kdb`, a KDBX pre-release) is reported inline instead of embedding anything; a completely unrecognized file gets the same treatment.
+
+On save, since there is nowhere to write back to, the local connector downloads the updated bytes the same way `0x67.html` would if opened standalone — the only piece of this connector that's genuinely local-specific.
+
 ## How the Google Drive connector works
 
 `cloud-google-drive.html` never parses or decrypts anything itself. It signs in to Google, lets the user pick a `.kdbx` file with the Google Picker, downloads its bytes, then embeds the real `0x67.html` app in an iframe and hands it those bytes. All the unlocking, browsing, and editing is the ordinary, unmodified app; the connector only fetches the file and writes it back.

 ## Local storage
 
-Opening a database from local disk needs nothing but the file itself: no account, no sign-in, no network connection. `router.html` and `0x67.html` work completely offline, so a vault on a USB drive or a personal laptop opens the same way whether there's an internet connection or not. Nothing about the file goes anywhere — there's no vendor, no OAuth exchange, and no service to trust beyond the browser itself. Opening a local file needs no account of any kind and is open to every visitor.
