IPC layer

Mimic uses Tauri's invoke() for all Rust ↔ TypeScript communication. src/lib/ipc.ts wraps every IPC call and provides mock fallbacks for browser preview.

Commands

Command	Parameters	Returns	Description
scan_profiles	configPath, credentialsPath	CloudProfile[]	Read ~/.aws/config + SSO/STS cache

logout_profile	profileName, configPath, credentialsPath	void	Clear active profile + cache
try_silent_refresh	profileName, configPath	boolean	Attempt aws sso login --no-browser
check_auth_status	profileName, configPath, credentialsPath	AuthStatus	Check SSO cache expiry
load_app_config	none	AppConfig	Read ~/.config/mimic/config.json
save_app_config	config	void	Write ~/.config/mimic/config.json
set_default_profile	profileName	void	Write active_profile.sh
clear_default_profile	none	void	Clear active_profile.sh
set_app_presence	mode	void	Show/hide dock icon
cancel_login	profileName	void	SIGKILL child process
cancel_identity_sync	sessionName	void	Cancel in-progress sync
update_tray	profiles	void	Rebuild tray menu

Browser preview fallback

When __TAURI_INTERNALS__ is not available (browser preview via npm run dev), IPC calls fall back to:

• Mock data (src/lib/mockData.ts)
• localStorage for config operations

This allows frontend development without the Tauri backend running.

Throttling

The sync_profiles_for_identity_provider command enforces a 50ms minimum interval between API calls to avoid throttling from Identity Center.
