Two first-run walls hit by git clonebun installbun run desktop on Linux.

#1664resource path ../../frontend/dist doesn't exist

frontend/dist is a bundle.resources entry; Tauri's build script refuses to compile when it is missing, even under tauri dev where Vite serves the UI. scripts/desktop-dev.mjs now creates the placeholder before spawning tauri dev. Regression test pins the ordering.

#1665 — AMD GPU never detected on source installs

uv sync restores the lockfile CUDA torch (CPU-only on AMD) and dev:api uses uv run, which re-syncs before every launch, so a hand-swapped ROCm wheel was reverted on the next start. OMNIVOICE_TORCH_VARIANT=rocm was only honoured by the packaged app bootstrap (bootstrap.rs).

  • scripts/setup.py: performs the same swap after the sync (same pins/index as bootstrap.rs, idempotent, warns instead of failing) — Linux only, opt-in only, default path unchanged.
  • scripts/dev-backend.mjs: uv run --no-sync when the variant is set.
  • Test guards pin/index drift against bootstrap.rs; docs/install/linux.md documents the source-install path.

Verified on an RX 6800 XT (Ubuntu 24.04 distrobox): detect_host_caps().family == "rocm", torch 2.8.0+rocm6.4. Full tests/ suite passes locally.

🤖 Generated with Claude Code

The source-install workflow now creates frontend/dist before tauri dev and supports opt-in AMD ROCm Torch packages through OMNIVOICE_TORCH_VARIANT=rocm. This prevents fresh-clone failures and preserves ROCm packages after uv sync. Review the non-fatal ROCm reinstall path and configured package index for environment compatibility.

frontend/dist is a bundle.resources entry, and Tauri's build script refuses
to compile when a listed resource path is missing — even under tauri dev,
where Vite serves the UI and dist is never produced. A fresh clone died with
"resource path `../../frontend/dist` doesn't exist". Create the placeholder
before spawning tauri dev; regression test pins the ordering.

uv sync always restores the lockfile's CUDA torch build (CPU-only on AMD),
and dev:api's uv run re-synced before every launch, so a hand-swapped ROCm
wheel was reverted by the next bun run desktop. The opt-in only existed in
the packaged app's bootstrap.rs. scripts/setup.py now performs the same
swap after the sync (same pins/index, idempotent, warns on failure) and
dev-backend.mjs launches uv run --no-sync when the variant is set. Test
guards pin/index drift against bootstrap.rs.

Greptile Summary

The PR repairs fresh-clone desktop development startup and adds an opt-in ROCm PyTorch setup path for Linux source installs.

  • Creates the required frontend/dist resource before launching Tauri development.
  • Reinstalls pinned ROCm PyTorch packages after dependency synchronization and prevents the backend launch from immediately reverting them.
  • Documents and regression-tests both source-install workflows.

Important Files Changed

Filename Overview
scripts/desktop-dev-launch.mjs Creates the required frontend distribution placeholder before spawning the workspace-local Tauri development command.
scripts/desktop-dev.mjs Delegates Tauri startup to the new resource-preparation helper while preserving environment repair and exit handling.
scripts/dev-backend.mjs Adds uv run --no-sync only for explicit ROCm source launches so the installed ROCm wheel remains active.
scripts/setup.py Adds a Linux-only, explicitly opted-in ROCm PyTorch reinstall using the pinned package family and configured index.
tests/test_desktop_dev_dist_placeholder.py Verifies that the resource directory is created before Tauri is spawned and that arguments and environment are preserved.
tests/test_setup_rocm_variant.py Pins ROCm opt-in behavior, package versions, index parity, and backend no-sync argument construction.

📝 Walkthrough

Walkthrough

The change adds opt-in ROCm Torch installation for Linux source setups, prevents backend dependency resynchronization for ROCm launches, and centralizes Tauri resource-directory creation before desktop startup.

Changes

Desktop setup fixes

Layer / File(s) Summary
ROCm Torch setup flow
scripts/setup.py, docs/install/linux.md, tests/test_setup_rocm_variant.py
Linux source setup supports explicit ROCm selection, configurable indexes, pinned package reinstalls, and runtime validation.
ROCm-aware backend launch
scripts/dev-backend.mjs, tests/test_setup_rocm_variant.py, CHANGELOG.md
The backend uses uv --no-sync when ROCm is selected. Runtime tests validate variant handling, and the changelog records the macOS subprocess fallback fix.
Desktop resource directory creation
scripts/desktop-dev-launch.mjs, scripts/desktop-dev.mjs, tests/test_desktop_dev_dist_placeholder.py, CHANGELOG.md
The launcher creates frontend/dist before Tauri startup. The test uses a dynamic working directory and verifies the generated path.

Full details: Cross-Platform Default Parity

Explanation

No default-mode platform divergence was introduced. The default bun run desktop path now calls launchTauriDev, which uses platform-native path.join and recursive directory creation without an OS branch, then performs the same Tauri spawn on macOS, Windows, and Linux. The ROCm changes are explicit opt-in through OMNIVOICE_TORCH_VARIANT=rocm; setup applies them only on Linux, and uvRunArgs changes arguments only when that variable is set. With the variable unset or set to auto, the existing behavior remains unchanged.

Full details: I18n Completeness (21 Locales)

Explanation

No frontend files changed in the PR diff from merge base 032c5ab to HEAD. Therefore, the PR adds or changes no frontend t('...') keys and introduces no frontend user-facing strings that bypass i18n.

Full details: Local-First Guarantee

Explanation

The PR adds a non-allowed outbound download for opt-in source ROCm setup. scripts/setup.py:51,70-89,211-213 runs uv pip install against https://download.pytorch.org/whl/rocm6.4 when OMNIVOICE_TORCH_VARIANT=rocm, and OMNIVOICE_TORCH_INDEX permits any user-supplied external index; this path is activated by bun run setup:api in package.json. No new account, API key, or telemetry behavior was found, but PyTorch package traffic is outside the permitted GitHub Issues and HuggingFace traffic.

Resolution

Remove the automatic ROCm wheel download and the arbitrary remote index override from source setup. Detect an existing ROCm installation and continue offline; require users to provide wheels through a local path or configured local cache, or vendor the required packages. Update the ROCm documentation and tests so bun run desktop performs no non-permitted network request.

Full details: Backward Compatibility

Explanation

PASS — The feature diff changes only launch/setup scripts, documentation, and tests; it adds no database or schema changes, and no migration is required. The ROCm path is opt-in and only reinstalls pinned Torch packages in the current venv; it does not remove or relocate omnivoice_data, database files, engine installations, or model caches. The desktop helper creates only frontend/dist, while the default non-ROCm launch path remains unchanged.
