Leads on Tauri - Linux, Windows, macOS

The Leads desk is not a per-OS binary. One Rust shell (desktop/src-tauri) opens the splash, starts the Python gateway, then navigates the WebView to http://127.0.0.1:<port>/#/leads. The navin-dist sidecar (Linux / Windows / macOS / macos-x64) does not embed Leads logic: it is the same frozen Python as Career, Marketing, Tenders and Trading. PyInstaller collects navin.leads on every OS. Sidecar and smoke tests import navin.leads.desk_cli before the bundle is shipped.

WebView origins

is_desktop_app_url (Rust) and isDesktopAppUrl (TypeScript) keep the hash in the app.

OS	Typical origin	Example that stays in the WebView
Linux	`http://127.0.0.1:<port>`	`http://127.0.0.1:8766/#/leads?lead=abc`
Windows	splash `https://tauri.localhost` (WebView2), then loopback	`https://tauri.localhost/#/leads?pane=book`
macOS	`tauri://localhost`	`tauri://localhost/#/leads`

on_navigation: internal URL → stay. External URL → OS browser, navigation denied. on_new_window: target=_blank on #/leads applies the hash on the main window (apply_in_app_navigation). Official portals leave.

gateway-opener.json capability: platforms linux, macOS, windows. Remote hosts: http://127.0.0.1:*, http://tauri.localhost, https://tauri.localhost (WebView2), tauri://localhost. https://** permissions for Hunter, SIRENE, Apollo, and the rest.

Splash vs UI bundle

frontendDist points at desktop/ui: boot page only. Studio UI is the Vite build served by the gateway:

Source: webui/
Build: tsc -p tsconfig.build.json && vite build
Output: navin/web/dist/ (lazy chunk LeadsWorkspace-*.js)

A per-OS tauri build does not add Leads code. Integration check = same interceptor + same opener + same dist.

Links and tests

Provider catalog: webui/src/lib/leads-catalog-urls.json - every URL leaves the IDE (every_leads_catalog_url_leaves_the_ide).
Rust tests: tauri_custom_protocol_stays_in_the_webview (all three origins plus ?lead= / ?pane=book).
JS tests: webui/src/lib/desktop.test.ts, leads-api.test.ts, leads-ui.test.ts.
Wiring: tests/test_leads_wiring.py, tests/test_desk_tauri_packaging.py (opener on 3 OS, sidecars without leads / heartbeat).

The agent sandbox allows writes under ~/.navin/leads.
