Is there a full "research tree" for all of the upgrades possible for gear, items, and housing?

Similar to XCOM 2 and it's ridiculously crazy research tree, is there a flowchart guide as to what possible upgrades there are in the game, and how to go about getting them?

For instance, there are some which I don't know the full extent of how it upgrades, but at least have a partial idea:

  • Housing
    • Tent (Free) -> Pay off 5,000 Mile debt to Tom, -> House (98k Bells) -> ???
  • Tools
    • Flimsy Tools -> Pay off 5,000 Mile debt to Tom -> Unlock Nook Miles+ -> Redeem 3000 Nook Miles for "Pretty Good Tools" kit -> ???
  • Quality of Life
    • Pay off 5,000 Mile debt to Tom -> Unlock Nook Miles+ -> Redeem 800 Nook Miles for "Tool Ring" -> ???
  • Inventory
    • Pay off 5,000 Mile debt to Tom -> Unlock Nook Miles+ -> Redeem 5000 Nook Miles for "Bigger Pockets" -> ???

Solution 1:

Well it's not a tree—it's single-path, though not necessarily sequential for the tools.

House upgrades

  • Tent (5k miles)
  • House and storage feature (98k bells)
  • Larger floor plan (198k bells)
  • Room in back of house (348k bells)
  • Larger house and external decorations (548k bells)
  • Rooms on left and right of first floor (758k bells)
  • Second floor (1.2m bells)
  • Basement (2.5m bells)

Tools

  • Flimsy (through story)
  • Regular (through story)
  • Colorful/Outdoorsy (customized) in upgraded Nook's Cranny
  • Golden (see requirements)

To my knowledge, as of now there are no further "quality of life" or inventory upgrades.
