DPDD incorrectly states "immediate" access to PPDB products

      Description

      Section 3.3 says:

      The described alert processing design relies on the “living” Level 1 database that contains the objects and sources detected on difference images. [...] As these get updated and added to, their updated contents becomes visible (query-able) immediately.

      This is inaccurate, as the database baseline requires users to access a replicated version of the PPDB, and the timescale for that replication is not yet decided. DMS-REQ-0004 requires that the nightly products be accessible in less than L1PublicT, which is currently 24 hours.

      I think it is generally expected we can replicate the database much faster than once per day, but I don't believe there's a solid number we can provide.
