Client Extensions

Plugins can only mount into PayIncus-approved extension slots. They cannot directly modify the main frontend source code.

User Slots

user.sidebar.extra
user.dashboard.cards
user.instance.detail.panels
user.instance.renew.widgets
user.wallet.extra
user.ticket.extra
public.market.cards

Admin Slots

admin.plugins.settings
admin.sidebar.extra
admin.dashboard.widgets
admin.instance.detail.panels
admin.user.detail.panels
admin.billing.extra
admin.ticket.extra

Plugin pages are loaded in sandboxed iframes. A plugin can read its own public config, but it cannot bypass permissions or call admin APIs from the user portal.
