Normalized owner activity events

Returns one deterministic timeline across the requested chains and the owner's complete 256-address EVC account family, spanning the owner at ID 0 through subaccount ID 255. Account identities are excluded from request logs and persisted endpoint telemetry. Coverage is aggregated across chains and reports incomplete reward claims or unclassified multiply intent as partial. Unsupported sources and indexer synchronization state are explicit in meta.coverage. Any positive safe-integer chain ID is accepted; chains without V3 Activity indexing return HTTP 200 with an empty timeline and per-chain unsupported coverage. Governance actor and before/after enrichment, underlying-asset metadata and valuation, and swap asset/vault mapping can be unavailable. Missing normalized values stay absent, source fields remain in payload, and coverage continues to describe indexed event-family availability. Transient projection failures retain indexed events and report partial coverage rather than authoritative unsupported or complete coverage.
