2026-05-13: Fix Tauri Prod — Wrong DB Path and Wrong Version

Fix: Tauri Prod — Wrong DB Path and Wrong Version

Problems

1. Seeded demo data instead of real production data

npm run tauri:prod builds and opens Strata.app. The app showed seeded demo data instead of the user’s real assets.

Root cause: Two separate database files, neither pointing to the same location:

• Docker prod (npm run docker:prod): backend/.data/strata.db ← real data
• Tauri prod (.app): ~/Library/Application Support/Strata/strata.db ← created fresh → seeded

The user expects tauri:prod and docker:prod to share the same strata.db — the intended workflow is: run web app → close → open desktop app → see the same data.

2. Version displays 1.1.0-2-gc6c9ce4-dirty

Should display 1.1.0. Root cause:

• tauri-build.sh does not set VERSION_OVERRIDE, unlike docker:prod
• git describe --tags --dirty --always returns the full string with commit count and dirty suffix
• src-tauri/build.rs calls version.mjs --json directly (no VERSION_OVERRIDE)
• Git tree is dirty: front/.astro/types.d.ts + src-tauri/Cargo.lock are modified

Fixes

Fix 1: Share DB between Docker prod and Tauri prod

Change data_dir() in src-tauri/src/lib.rs: Remove the dev/prod branch — always use <repo>/backend/.data/, same as the dev build and Docker:

repo/backend/.data/

// Before (prod branch):
fn data_dir() -> std::path::PathBuf {
    if is_dev_build() {
    } else {
        // ~/Library/Application Support/Strata/
    }
}

// After (unified):
fn data_dir() -> std::path::PathBuf {
    // Both dev and prod Tauri builds use backend/.data/
    // This matches Docker dev (strata-dev.db) and Docker prod (strata.db)
    let manifest = std::path::Path::new(env!("CARGO_MANIFEST_DIR"));
    let repo_root = manifest.parent().expect("CARGO_MANIFEST_DIR has no parent");
    repo_root.join("backend").join(".data")
}

Remove the now-unused dirs crate:

• src-tauri/Cargo.toml: remove dirs = "6"
• src-tauri/build.rs: no change needed (dirs not used there)

Fix 2: Correct version in tauri-build.sh

Add VERSION_OVERRIDE to scripts/tauri-build.sh (mirrors docker:prod behavior):

# After the root npm install, before any build steps:
export VERSION_OVERRIDE="$(git describe --tags --abbrev=0 2>/dev/null)"

Add cargo:rerun-if-env-changed to src-tauri/build.rs:

println!("cargo:rerun-if-env-changed=VERSION_OVERRIDE");

This ensures cargo reruns build.rs when VERSION_OVERRIDE changes (otherwise cached).

Files Changed

File	Change
src-tauri/src/lib.rs	Simplify data_dir() — always return backend/.data/
src-tauri/Cargo.toml	Remove dirs = "6" dependency
scripts/tauri-build.sh	Add export VERSION_OVERRIDE before build steps
src-tauri/build.rs	Add cargo:rerun-if-env-changed=VERSION_OVERRIDE
docs/src/content/docs/DesktopApp.md	Update DB path docs — prod now uses backend/.data/

Acceptance Criteria

1. npm run tauri:prod opens app showing real production assets (from backend/.data/strata.db)
2. Version displays 1.1.0 (or latest clean tag) — no -dirty, no commit count
3. File → Reveal Data Folder opens backend/.data/ in both dev and prod Tauri builds
4. DesktopApp.md updated to reflect shared DB path

Execution Summary

Commit: 6558f43

Actual changes

• src-tauri/src/lib.rs: Simplified data_dir() — removed prod branch pointing to ~/Library/Application Support/Strata/; both dev and prod now return backend/.data/
• src-tauri/Cargo.toml: Removed dirs = "6" (no longer needed)
• src-tauri/Cargo.lock: Auto-updated by cargo (dirs and its transitive deps removed)
• scripts/tauri-build.sh: Added export VERSION_OVERRIDE="$(git describe --tags --abbrev=0 2>/dev/null || true)" after root npm install
• src-tauri/build.rs: Added cargo:rerun-if-env-changed=VERSION_OVERRIDE
• docs/src/content/docs/DesktopApp.md: Updated all DB path references; architecture diagram updated

Deviations from plan

None. All changes implemented exactly as planned.

Test results

Gate	Result
Backend unit	⏭ not affected
Backend e2e	⏭ not affected
Frontend unit	⏭ not affected
Frontend e2e	⏭ not affected
Infra (tauri-build.sh)	✅ full build succeeded; version shows 1.1.0 (production); Strata.app produced

Key discoveries

• The -dirty in the version string came from front/.astro/types.d.ts and src-tauri/Cargo.lock being modified in the working tree — VERSION_OVERRIDE bypasses all git describe output cleanly.
• dirs crate was the only external dependency added solely for the ~/Library/Application Support/ prod path; removing it reduces the dependency surface.
