2. Missing icons → user generated placeholder via PowerShell `System.Drawing` + `pnpm tauri icon`.
3. `notify::Watcher` trait not in scope (E0599) and `tokio::JoinHandle` ≠ `tauri::async_runtime::JoinHandle` (E0308 ×2) in `watch.rs` — fixed in commit `ab75ca9`.
4. `tauri-plugin-autostart` doesn't accept a `{"args":[…]}` block in `tauri.conf.json` — args go through the Rust `init()` call only. Removed the JSON entry in commit `8c25b01`.
- **Pivoted from cap estimation to real `/usage` data.** First version showed 999% red ring because the placeholder caps (200k/2M) were wildly under what a Max user actually does. Tier-detection from `.claude.json` improved defaults but still wasn't right; user pointed out they'd previously had an app showing real subscription %. Investigated and found:
- `/usage` slash command output isn't reachable via `claude --print` (LLM intercepts the literal string).
- The data isn't cached anywhere on disk between invocations.
- The OAuth credentials at `~/.claude/.credentials.json` work, but reusing them to call an undocumented endpoint felt fragile.
- **Solution: PTY-drive `claude` itself.** New `src-tauri/src/cli_usage.rs` spawns claude via `portable-pty`, sends `/usage`, parses the three rendered bars (Current session / Current week all / Current week Sonnet). 5-min refresh + manual button. ~3-5s per fetch. (commit `db9a10a`)
- **Bring-up gotchas while wiring the PTY drive on Windows:**
1. Settings UI was non-interactive earlier because of two compounding bugs — a) Save was silently failing because the autostart plugin threw "OS error 2" in dev builds (target\debug exe path is unstable) and we let it abort the save; b) my PowerShell `mouse_event` clicks weren't reaching WebView2 (legacy API on a transparent borderless host), making me think the user's clicks were broken too. Real-mouse clicks worked once Save stopped getting blocked. Fix: best-effort autostart toggle (commit `9786437`).
2. `paths::resolve_roots` was canonicalizing UNC paths to `\\?\UNC\…` form, which broke `Path::parent()` and made tier detection silently fail. Stopped canonicalizing (commit `c5c38d1`).
3. Default `wsl.exe -- claude` invokes a non-interactive non-login shell with no PATH; resolved by defaulting to `wsl.exe -d Ubuntu bash -lc claude` on Windows when wsl.exe is detected (commit `7504990`). The `-d Ubuntu` matters because user's default WSL distro was `docker-desktop` (Alpine; no claude, no bash).
4. Title bar buttons were inside `data-tauri-drag-region`; needed explicit `data-tauri-drag-region="false"` per button so clicks don't get interpreted as drag-start.
- **Final UX polish (this session):** widget made resizable (220×240 min, 300×320 default), inline-SVG ring scales via viewBox, background opacity bumped to 93% so files behind don't bleed through, scrollbar bug from `border + width: 100vw` overflow killed via `box-sizing: border-box` reset + `body { overflow: hidden }` (commits `f90bb3b`, `c38d895`).
- **Status:** widget is live on Windows showing real subscription percentages (72% session at end of session). 18 commits on `main`, all pushed. User is happy.
- Toolchain (rust/node/pnpm) NOT installed in this WSL environment — that's expected; the build runs on the Windows host. `cargo check` / `pnpm install` not run from here.
