Introduces a new "timeseries" microservice and module family (model, api, mongodb, service) that records the history of Thing properties and serves it back over HTTP, WebSocket and Connectivity. Ingestion is opt-in per property via the WoT ditto:timeseries annotation and is forward-only. ThingPersistenceActor hands modified events to a per-node publisher, which resolves the Thing's model and writes matching properties through the timeseries shard region. Nothing is backfilled, and deployments without the service pay nothing: the publisher is left null when the feature toggle is off. Storage uses native MongoDB Time Series collections, one per namespace, so per-namespace retention and dropping a tenant stay cheap. Retention defaults to 90 days with per-namespace overrides, reconciled onto existing collections via collMod on a namespace's first write after a restart. Reads are authorized per path under a dedicated READ_TS permission, since a property's history discloses more than its current value. The single-Thing endpoint supports keyset pagination, sort order, aggregation, time-zone-aware bucketing and linear fill. Cross-Thing aggregation (GET /timeseries/things) spans one namespace with groupBy and an RQL filter over ingest-time tags. Authorization is decided live and never stored alongside the data: a namespace-wide grant gates the request before any storage is touched, then every contributing Thing is verified against its own policy per path, because namespace root entries merge additively and a Thing's own policy can still revoke. Guard rails bound the cost at 100 paths per query and 1000 verified Things; exceeding either fails the request rather than returning a truncated answer. The backend sits behind a TimeseriesAdapter interface with an explicit capability declaration, so a backend that cannot push an aggregation down falls back to a shared compute kernel. A conformance suite pins both paths to identical results. Also adds the Ditto Protocol adapters and the "aggregate" topic action, the Helm chart gated behind timeseries.enabled=false, OpenAPI definitions, documentation and UI support.
