Saving a file via puter.ui.showSaveFilePicker from a third-party website (popup flow) consistently failed with a DataCloneError alert after clicking Save, and saving over an existing filename showed a raw error instead of the Replace/Cancel prompt. Two bugs: 1. privacy_aware_path is a curried factory (world => fspath => ...), and initgui.js is the only module that imports it directly — so the popup save handler's privacy_aware_path(res.path) returned the inner function, which postMessage cannot structured-clone. Every other call site resolves the bare name to the correctly bound window.privacy_aware_path global, which is why only the external-site popup flow was broken. Use the global at the call site and import the factory under a distinct name so a bare call can't silently resolve to it again. 2. The v2 backend returns `conflict` for a same-name write, but the v1 wire contract is `item_with_same_name_exists` + `entry_name`, which the GUI's save dialogs key on to offer the overwrite prompt. Restore the legacy code/field on the write-conflict error and carry HttpError.fields through the /batch per-op error serializer. Verified end-to-end against a local backend: fresh save resolves the caller's promise with the signed saved_file and closes the popup; saving an existing name shows Replace/Cancel and Replace overwrites. Backend suite shows no new failures.
