- host plugins.rs: PERMISSIONS, parse_permissions, ScriptPlugin.permissions/problems (None = legacy,
full API), validate_plugin (file name, 2 MiB, UTF-8 text without binary bytes, header with @name
and @version, valid @permissions, network:none refused when the code calls network APIs),
source_findings, PluginStore::install (atomic rename, never enables, keeps the enabled state on
update) / remove / is_enabled / file_hash. start/stop scripts run the module body, construction,
start() and stop() inside window.<global>.withPlugin(id, grants, fn) when the runtime has it.
- runtime permissions.ts: parsePermissions, scopePluginApi (undeclared gated members throw a
PluginPermissionError; scope().ui gated like api.ui), createPluginContext (the view of the plugin
whose code runs; legacy = full API). A declaration and guard rail, not a sandbox.
- The `commands` permission name comes from the parallel palette-commands work (its API lands there).
tao's thread event target and the single-instance message window are visible
1 px unowned top-level windows. taskkill /PID (WM_CLOSE, no /F) closes only the
first such window in z-order; a minimized app window sinks below them, so the
close destroyed a helper and the app kept running. route_helper_closes
subclasses those helpers and forwards WM_CLOSE to the app window.
tauri 2 (runtime-wry build_gtk with the window's GtkBox) packs every child
webview into the window box, stacked and with set_position/set_size ignored,
so tab webviews landed under the shell instead of over their panes.
place_child/attach_shell move them into a GtkOverlay (shell as base layer)
and allocate each at its exact rect via get-child-position; placed_rect
reports the placement (GTK children have no position). Windows/macOS keep
set_position/set_size.
set_tab_visible shows/hides a tab webview and sets
ICoreWebView2_19::SetMemoryUsageTargetLevel (LOW when hidden, NORMAL when
shown). Hidden tabs keep running; the browser trims their working set.
Site-agnostic parts of the X app, behind a small site adapter:
- crates/waybetter-host: webview-label security policy and tab rect
clamp, account profiles with native-owned accounts (AccountRules),
plugin store with bundled-plugin upgrades (PluginHost), signed
data-only hotfix channel, update scheduling and crash handshake, tab
payloads/link routing/tab-chrome validation, and (feature "tauri")
webview helpers and the Windows system menu.
- packages/runtime: DOM hub, request hub, plugin API core, OKLab theme
color model, split-view rail hiding, link routing and account
reporting, each configured by a SiteAdapter.
- packages/shell: address bar, pane, link-drop, profile, palette and
update-chip models, and window controls with the Tauri API injected.
Tests moved/adapted from the app: 45 Rust (headless), 40 TypeScript.
