Spade oracle has real-time source of truth on all sector states

[xmcai2016]

ETA: 2024-02-29

• sqlite dumps on sector state across the network
• dependency for MPL50 in observing chain state and enabling deal proposing
• nv21 will require investment here in oct/nov (rebranding from “Deals Oracle” - change in scope due to FIP to remove deals on Filecoin)

This will probably be more than just spade oracle, and a more general oracle, no?

Spade user story: every ~2 hours I want to see the state and metadata of every sector on Filecoin today.

Expected consumers of the Oracle:

• Retrieval Bot v2
• Singularity
• Fil+ CID checker
• filecoin-tracker.com
• Dashboards owned by Network Growth
• and of course, Spade itself

@jlogelin to add expected dev tasks to the tasklist above after spec is finalized.

closing - out of scope as we'll use the one bundled as part of spade broker for now.
