NAV time-series of bound wallets, by address (fan-out)

By-address fan-out of the flow-adjusted NAV curve (persisted hourly snapshots + ledger net-deposits) — one call returns each provider's series for a user's addresses. Pass `walletAddress` (repeatable); `slices[i]` matches `GET /v1/me/wallets/{id}/nav-curve`; unbound addresses land in `warnings`. `window` = 1D/1W/1M/ALL (default ALL). This is the STATEFUL curve (needs binding); for a visitor/unbound address use the stateless `/v1/portfolio/nav`.
