ListFundNavHistory

Keyed by the ALLOCATION (the product's registry key — today equal to the service id) rather than the service, so a hidden allocation such as the fee fund can serve its holders' history later without a second route. from/to are unix seconds, inclusive; 0 means "from the first mark" / "up to now".

A fund's valuation log over the requested window (oldest first), and the caller's participation through it. participation steps at every mark and every change to the caller's units (subscribe, redeem, fee charge, in-kind issuance, book fill) and always ends at the window's end — "now" unless to was given — priced off the live holding, so the last point equals the position card. Empty marks means the fund is still on the seed NAV (or no mark fell in the window); it is not an error. truncated is true when more marks fell in the window than the cap allows and the OLDEST were dropped.
