Summary

  • Browse on the folder memory-source now opens the OS-native directory chooser and stores the absolute path it returns.
  • The webkitdirectory fallback can no longer store a value that cannot work: when File.path is absent it reports an error next to the field instead of saving the bare directory name.
  • Backed by rfd, already in this shell — no new dependency, no dialog plugin, no capability-allowlist entry.
  • Hand-typed absolute paths are untouched. That is the current workaround and people are relying on it.

Problem

AddMemorySourceFields.tsx rendered Browse as <input type="file" webkitdirectory>. That element carries no filesystem path. Chromium exposes one on the non-standard File.path only when the renderer has filesystem-aware integration, which the code's own comment said outright. Outside that renderer the handler fell through to:

} else if (first.webkitRelativePath) {
  onChange(first.webkitRelativePath.split('/')[0]);   // the folder NAME, location discarded
}

A user who picked a folder got a source storing docs. Every sync then failed, once per cycle, indefinitely:

WRN pipeline tick failed pipeline_id="workspace:folder:src_d9a41ccf…"
    error=not found: folder does not exist: docs

Re-adding the same folder with a hand-typed absolute path worked immediately on the same build, same reader, same module. Only the path form differed.

The failure surfaces at sync time, far from the picker that caused it, and it never stops. Nothing in between could repair it, because there is nothing to repair: docs is not a relative path, it is a name whose location was thrown away.

Why openhuman#5830 / tinycortex#158 do not cover this

Those resolve a relative path against the workspace, which is correct and unrelated. Resolving docs gives <workspace>/docs — still not the directory the user chose. The user would get a different wrong answer with a better error message.

Solution

1. A native chooser (pick_directory_via_dialog)

What the app already had, since the brief asked. There is no @tauri-apps/plugin-dialog anywhere in this repo, and no existing frontend directory-picker helper. What does exist is artifact_commands::save_artifact_via_dialog (#3162) — a native Save-As dialog driven by the rfd crate, declared in app/src-tauri/Cargo.toml with default-features = false + xdg-portal (which is what keeps Linux off GTK). Its module doc records that it deliberately talks to the OS dialog APIs directly rather than pulling a Tauri dialog/fs plugin, after a schemars version conflict.

So this follows that precedent instead of adding the plugin the issue suggested: a sibling command in a new directory_picker module, ~15 lines, using the same rfd::AsyncFileDialog already compiled into this shell. No new dependency, no plugin, no capability entry, no permissions surface to get wrong across three platforms.

It takes no input and returns only what the user chose in an OS-owned dialog, so unlike the artifact commands there is no path to re-validate — that is noted in the module docs so the asymmetry does not read as an oversight.

2. Never store an unusable value

Selection logic moved into folderPicker.ts as two pure-ish functions returning a tagged result:

outcome meaning what the UI does
{ ok: true, path } an absolute path store it
cancelled user dismissed the chooser nothing, silently
unavailable no native chooser here fall back to the directory input
no-absolute-path a directory was chosen, its location is unknown show an error, store nothing

webkitRelativePath is deliberately no longer consulted as a fallback. Its first segment is the defect, not a degraded-but-usable answer.

3. Existence validation at save time — considered, and not added

The native chooser can only return a directory that exists, so the path this PR fixes is covered by construction. A hand-typed path that does not exist yet is a legitimate thing to configure ahead of creating it, which is why the issue asks for a hint rather than a rejection. Checking it from the renderer would need a new filesystem-read command and a new trust boundary for what is explicitly only a hint, and that is a bigger change than the defect warrants. Worth doing as its own piece if the hint is still wanted.

Testing

app/src/components/intelligence/__tests__/folderPicker.test.ts — 10 tests, all passing.

Revert-check

Restoring the pre-fix fallback (return { ok: true, path: webkitRelativePath.split('/')[0] }) fails the new assertions, reproducing the exact production value from the issue:

× refuses to produce a path when the renderer does not expose File.path
  AssertionError: expected { ok: true, path: 'docs' } to deeply equal { ok: false, … }
× never returns the bare directory name for any nesting depth
  AssertionError: expected true to be false

Tests  2 failed | 8 passed (10)

The other 8 keep passing, so the two that fail are the two that pin this defect.

Checks run

check result
vitest (the one new file) 10 passed
pnpm typecheck clean
pnpm i18n:check clean
pnpm i18n:english:check total unexpected English: 0
eslint (changed files) clean
prettier --check clean
cargo fmt --check (app/src-tauri) clean

Per the brief I did not run the full suite or a full build.

The Rust does not compile locally in this session — a cargo check of the Tauri shell is a full build of that crate. Instead I verified the two APIs against the exact vendored source (rfd-0.15.4): AsyncFileDialog::pick_folder(self) -> impl Future<Output = Option<FileHandle>> (file_dialog.rs:253) and FileHandle::path(&self) -> &Path (file_handle/native.rs:136) — the same pair save_artifact_via_dialog already uses in this crate. The rest is two lines in lib.rs. The Tauri lane covers it; flagging it rather than implying a check I did not run.

Also verified mod directory_picker; landed unguarded — it sits directly after mod deep_link_ipc_windows;, which consumed the #[cfg(target_os = "windows")] above it. A module declaration inserted next to a cfg is an easy way to silently platform-gate something that must exist everywhere.

i18n

One new key, memorySources.folderPathUnavailable, with a real translation in all 14 locale files (ar, bn, de, en, es, fr, hi, id, it, ko, pl, pt, ru, zh-CN). No em dashes, per the repo rule. i18n:english:check confirms none was left as English.

The error text avoids naming the mechanism and says what to do instead: "Could not determine where that folder is. Type its full path instead."

Impact

Desktop and browser. No migration, no schema change, no config change. Existing folder sources are untouched — this only changes what a new selection can produce. A source already poisoned with a bare name still needs re-adding; nothing here can recover the location that was discarded when it was saved.

Submission Checklist

  • Tests added: folderPicker.test.ts, 10 cases. Failure path is the revert-check above, plus explicit coverage of cancellation, an unavailable dialog, a blank return, and Windows separators.
  • N/A: diff coverage. The changed frontend lines are covered by the new test; the ~15 Rust lines are a dialog invocation with no branching logic to assert without a real OS dialog.
  • N/A: no feature rows added, removed, or renamed.
  • N/A: no feature IDs affected.
  • No new external network dependencies introduced. rfd was already a dependency of this shell.
  • N/A: does not touch release-cut surfaces.
  • Linked issue closed via Closes tinyhumansai/openhuman#5831.

Impact (platform)

Desktop (macOS/Windows/Linux) gains the native chooser; a browser context keeps the input fallback and now fails visibly instead of silently. No performance, security, migration, or compatibility implications.

Behavior Changes

  • Intended behavior change: Browse opens a native chooser; a selection that yields no absolute path is refused with a visible error rather than silently stored.
  • User-visible effect: folder sources added via Browse now sync. A failed selection says so immediately instead of failing at every sync forever.

Parity Contract

  • Legacy behavior preserved: hand-typed absolute paths, and the File.path derivation where the renderer supplies one, both behave as before.
  • Guard/fallback/dispatch parity checks: the webkitdirectory input remains the fallback for browser contexts and hosts with no working dialog; only its unusable output was removed.

… a bare folder name

The folder memory-source picker is an `<input type="file" webkitdirectory>`.
That element carries no filesystem path: Chromium exposes one on the
non-standard `File.path` only when the renderer has filesystem-aware
integration. Outside that renderer the handler fell back to

    onChange(first.webkitRelativePath.split('/')[0]);

which is the chosen directory's NAME with its location discarded. A user who
picked a folder got a source storing `docs`, and every sync then failed
forever with `folder does not exist: docs`. Re-adding the same folder with a
hand-typed absolute path worked immediately on the same build.

Browse now calls the OS-native directory chooser through a new
`pick_directory_via_dialog` Tauri command, which returns an absolute path in
every renderer and on every platform. It is backed by `rfd`, already in this
shell for `save_artifact_via_dialog` (tinyhumansai#3162), so there is no new dependency,
no dialog plugin, and no capability-allowlist entry.

The `webkitdirectory` input is kept as the fallback for a browser context and
for a host with no working dialog, but it can no longer produce a bad value:
when `File.path` is absent it reports `no-absolute-path` and the field shows
an error instead of saving a name that cannot resolve. Hand-typed absolute
paths are untouched, which matters because that is the current workaround.

Not added: existence validation at save time. The native chooser can only
return a directory that exists, so the path this fixes is already covered by
construction, and a hand-typed path that does not exist yet is a legitimate
thing to configure ahead of creating it. Checking it from the renderer would
need a new filesystem-read command and a new trust boundary for what the
issue itself asks be only a hint.

📝 Walkthrough

Walkthrough

The folder memory-source picker now uses a native Tauri directory dialog, validates absolute paths, supports a browser fallback, reports unresolved paths, and adds localized error messages. Tests cover native and browser path-selection outcomes.

Changes

Folder picker integration

Layer / File(s) Summary
Native directory dialog
app/src-tauri/src/directory_picker.rs, app/src-tauri/src/lib.rs
Adds and registers pick_directory_via_dialog. The command returns an absolute path, cancellation, or an error.
Path resolution and validation
app/src/components/intelligence/folderPicker.ts, app/src/components/intelligence/__tests__/folderPicker.test.ts
Adds typed picker results, native invocation handling, browser path extraction, and tests for cancellation, unavailable dialogs, invalid paths, and platform separators.
Folder field behavior and messages
app/src/components/intelligence/AddMemorySourceFields.tsx, app/src/lib/i18n/*.ts
Uses the native picker with a hidden-input fallback. Displays an alert when the folder path cannot be determined. Adds translations for supported locales.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟠 High · up to b8943

Browse can still save the wrong location, such as a parent folder or file path, which may cause unintended files to be indexed or syncs to fail. The selected absolute path is also written to logs and may expose private directory names. These issues should be fixed before merge.

Poem

A rabbit taps Browse beneath the moon,
The native chooser answers soon.
Full paths hop safely through the gate,
A fallback waits when Tauri is late.
Translations bloom in every row,
And folder paths now clearly show.

P1 Badge Grant the picker command in the main-window capability

In the shipped desktop context, this invoke is denied by Tauri's ACL because pick_directory_via_dialog was registered in generate_handler! but was not added to any permission TOML or to capabilities/default.json; the neighboring artifact dialog commands require explicit allow-artifact-* grants. The catch then converts that denial to unavailable, so Browse falls back to the pathless webkitdirectory input and the new native chooser never opens. Add an allow permission for this command and include it in the main-window capability.

For /Users/you/notes/readme.md with notes/readme.md, this returns /Users/you, one level above the selected folder.

Closing this — the native chooser it adds cannot run in the renderer the app ships. Recording the findings so none of the work is lost.

What was right, and should come back

The refuse-to-store guard is correct and valuable. On main, picking a folder in a non-CEF renderer silently stores the bare directory name and produces a source that looks configured and can never sync (#5831). With this PR the field reports the failure instead. That behaviour was verified by hand: Browse produced "Could not determine where that folder is. Type its full path instead." rather than silently saving docs.

The Rust half is also correctly wired — mod directory_picker; (lib.rs:46) and directory_picker::pick_directory_via_dialog in the invoke_handler (lib.rs:3375). Nothing is wrong there.

Why it cannot work as written

folderPicker.ts:93-96 gates the native path on isTauri():

export async function pickDirectoryNatively(): Promise<FolderPickResult> {
  if (!isTauri()) return { ok: false, reason: 'unavailable' };

and isTauri() (common.ts:30-44) requires window.__TAURI_INTERNALS__.invoke, logging "isTauri() -> false: IPC bridge not wired (CEF bootstrap…)" when absent.

The app runs CEF. Measured on a live build: 66 CEF helper processes, a per-user cef/ directory, and the shell starting its own transport because Tauri IPC does not exist there:

[webview_apis] server listening on 127.0.0.1:53495 (OS-assigned ephemeral)
[webview_apis] bridge ready on port 53495

So isTauri() is correctly false, pickDirectoryNatively() short-circuits to unavailable, the webkitdirectory fallback runs, cannot produce a path, and the user sees the error. Browse is unusable in the shipping renderer.

Worth stating plainly to avoid repeating it: this PR moved off File.path because that only exists under CEF, and landed on a transport that only exists under Wry. Wry has never shipped.

Why CI did not catch it

folderPicker.test.ts mocks the invoke layer, so it passes whether or not the transport exists. The defect is only observable by clicking Browse in a running CEF build. A test that mocks the transport proves the logic, never the wiring.

What a replacement needs

  1. Reach the shell over the transport that works under CEFwebview_apis is the obvious candidate; confirm against a command that demonstrably works in a running build rather than assuming.
  2. Work in both renderers, and say explicitly how each reaches it.
  3. Keep this PR's guard verbatim. It is the part that protects users when no path can be obtained.
  4. Reconsider whether isTauri() is the right gate, or whether the question is "can I reach the shell?" rather than "am I under Tauri?".

#5831 stays open — the defect it describes is real and still unfixed. Only this approach is being withdrawn.

Current workaround for users: type an absolute path. That works today and is unaffected by any of this.

Folder picker silently stores only the directory NAME when File.path is unavailable, creating a source that can never sync
