Package application implements the client-application subdomain of the subscription module: managing the subscribe clients and previewing their delivery templates.

Package deduction provides functionality for calculating remaining amounts in subscription billing systems, supporting various time units and traffic-based calculations.

Package delivery implements the subscription delivery subdomain of the subscription module: token-authenticated rendering of client configs via the adapter, with notice placeholders for expired/exhausted subscriptions.

Package fulfillment applies a paid order's business effect: creating, renewing or traffic-resetting the user subscription in the fulfillment transaction, idempotent via the inbox marker.

Package inventory reserves and restores plan stock for orders, each at most once per order through inbox markers.

Package nodeaccess serves the subscription side of node access to the other modules (ADR-001 rule 4): the subscriptions the network may serve, found by token, id or node scope together with their plans, and the cache invalidation when an account's access ends.

Package period holds the subscription module's calendar rules: the time units that size a subscription term and the traffic reset cycles of a plan.

Package plan implements the subscription plan management subdomain of the subscription module: plan and group CRUD, ordering and token resets.

Package quotatask processes the admin-scheduled quota grants: extending subscription time and crediting gift money for a scope of subscriptions.

Package render builds the client configurations of subscription delivery and template previews: it maps nodes to the proxies a client template renders and executes the template in the application's output format.

Package repo holds the subscription module's repository implementations: plans and groups, user subscriptions with their traffic accounting and cache bridges, client applications and provider entitlements (ADR-001 step-6 preparation).

Package selfsub implements the user self-service subscription management of the subscription module: viewing, token reset, notes, and the two-phase cancellation whose refund stage the billing module settles.

Package storefront implements the public subscription listings of the subscription module.

Package subtest is the subscription module's behaviour-test fixture: a SQLite database with the module's tables and a miniredis cache behind the module's real repositories.

Package sweep implements the subscription lifecycle sweep: marking traffic-exceeded and expired subscriptions finished, then firing the retryable side effects (owner notification, cache invalidation).

Package trafficreset applies the plans' calendar traffic resets: on the 1st of every month, monthly on the start day and yearly on the start date (the rules live in period).

Package trafficusage owns idempotent subscription usage accounting.

Package trial grants the registration trial subscription.

Package usersub implements the admin-side user subscription management of the subscription module.
