+
+**Serving subscriptions from the service.** Pass
+`reporting_subscriptions=ReportingSubscriptionServiceOptions(...)` to
+`ReliableReportingService`. Without it, capabilities, responses and worker
+turns are unchanged.
+
+```python
+from adcp.reporting.service_subscriptions import ReportingSubscriptionServiceOptions
+
+reporting = ReliableReportingService(
+    store=store,
+    account_context=resolve_account_context,  # also receives subscription generations
+    reporting_subscriptions=ReportingSubscriptionServiceOptions(
+        engine=engine,
+        list_principals=list_subscribing_principals,
+        resolve_principal=resolve_authenticated_principal,
+        definitions={"daily_v1": daily_definition},  # content-addressed, per offering
+    ),
+)
+```
+
+What the service does with it:
+
+- **Planning.** Each worker turn first plans every listed principal's frozen
+  owed set, then executes those obligations alongside the account
+  configurations.
+  - A subscription generation is one per (account, principal,
+    `subscription_id`, version, resolved `offering_id`). Its `consumer_id` is
+    the principal's `subject`.
+  - Each generation is installed through the same trusted path as
+    `configure()`. `account_context` receives it with
+    `configuration.subscription` set and returns the source route, currency
+    and advertised offering. The service validates these as it does for an
+    account configuration.
+  - Obligations are written only for periods ending by
+    `min(engine through, turn clock)`. Each carries exactly that period's
+    media buys and is never rewritten.
+  - A subscription that cannot be planned is recorded in
+    `turn.subscription_errors` and reported to `planning_error_handler` (or
+    the worker error handler). It never stops another subscription or an
+    account configuration.
+- **Capabilities.** The service adds `configuration_tasks`, the
+  `subscriptions` block, `standard_dimensions` on every offering, the feature
+  id and the principal section, at the release each caller is served.
+  - Callers served below 3.3 see the pre-3.3 block.
+  - The adcp#8585 offering fields reach only 3.3.0-beta.2 callers.
+  - Advertise `adcp.principal` yourself. The service refuses to advertise
+    subscriptions without it.
+- **Status.** `get_reporting_status` summary and periods views gain
+  `subscription_coverage[]`.
+- **Visibility.** Ledger reads and `sync_reporting_status` are scoped by the
+  caller's `consumer_id`, so a principal sees only its own subscription
+  periods. The caller resolver must therefore yield the principal's `subject`;
+  the service checks `resolve_principal` against it.
+
+**Grants: access means access.** `AuthorizedAccount.allowed_tasks` carries the
+grant's `authorization.allowed_tasks`.
+
+- Coverage continues only while the grant lists `get_reporting_status`; a grant
+  reduced below that ends coverage exactly like a revocation.
+- For a caller holding subscription generations on the account, the service
+  checks each reporting task against the current grant:
+  - `get_reporting_status`;
+  - `get_media_buy_delivery` exact reads;
+  - `sync_reporting_status`;
+  - `sync_reporting_receipts`.
+
+  A task the grant does not list fails with `ACCOUNT_NOT_FOUND`.
+- There is no window after a loss of authority: a revoked account is unknown to
+  every task, receipts and statuses included.
+- To let a buyer finish reconciliation, keep a reduced grant (for example
+  `get_reporting_status`, `sync_reporting_receipts` and `sync_reporting_status`)
+  rather than revoking.
+
+The beta.2 spec text still describes a post-revocation window; the beta.3
+change replaces it with this rule.
+
+**Limits.** These are not served yet:
+
+- the service refuses `production` options;
+- subscriptions that resolve a managed or receipt-reconciled offering;
+- status notifications for subscription generations: a PostgreSQL store with
+  them enabled refuses an owed set. `PgReportingLedgerStore` otherwise holds
+  owed sets, after the generation-key widening described in
+  [ledger migrations](reporting-ledger-migration.md).
+
+Keep the engine's `status_retention_days` equal to the service's.

+## Reporting-subscription generations: the widened key (AdCP 3.3)
+
+Reporting subscriptions keep one generation per resolved offering of a
+subscription version, so the generation key gains `offering_id`:
+`(account_id, consumer_id, delivery_config_id, delivery_config_version, offering_id)`.
+`ReportingConfigurationGenerationKey.offering_id` is `None` for every
+account-level generation, and their digests, work keys and persisted scopes are
+unchanged.
+
+In PostgreSQL this is a **stopped-worker maintenance upgrade**:
+
+1. Stop every reporting worker. Workers of earlier releases refuse the widened
+   schema; mixed-version workers are unsupported.
+2. Run `create_schema()` (or your usual migration entry point) once with the new
+   release. Under the schema lock it widens the key in place and losslessly:
+   - `reporting_configurations` gains `offering_id` (`''` for existing rows),
+     and its primary key includes it;
+   - `reporting_obligations` gains `offering_id`, and its period unique index
+     includes it;
+   - `reporting_consumer_statuses` gains `offering_id`;
+   - the SDK's own references (reconciliation records, materializer discovery,
+     status scope checkpoints, production generations) are re-pointed at the
+     widened key. They hold account-level generations only, enforced by a
+     `CHECK`, until each feature serves subscriptions.
+3. Restart the workers on the new release.
+
+A foreign key outside the SDK that references `reporting_configurations`
+refuses the upgrade with a maintenance error, rather than being dropped.
+Re-point it at the widened key, then run the upgrade. The upgrade is
+idempotent; a fresh schema is created in the widened layout directly.
