...is the watering can still partially full of water, because if Oliver put a watering can full of water into his backpack without closely observing this operation, that suggests his brain has some concerning blind spots whenever Oliver is not paying close attention to it.

Yes. The watering can looks like it could still water up to 25 more parsnips!

Oliver did not technically put it back into his backpack yet, as the last thing he decided to do was to water things, and then he didn't decide to do anything else.

Admittedly it is a little odd that the watering can is both in his hands and also taking up room in his backpack. Nevertheless.

It is not even slightly lost on Oliver that this seems like the signature of a manifested, full-dimensional world whose structure is based on some simpler world that had the form of a computer game programmed in a way where it used simple data structures to track things rather than a physics engine.  Several things have been pointing in this direction but this one is pretty strong.

Can Oliver, perhaps by giving way to his own instincts, store the watering can in the backpack and take it out again very quickly and without spilling anything?  And is it then still partially full of water?

The best way to do that would be to form an intention to do something with the mixed seeds. Oliver was already halfway to doing that a moment ago anyway.

So: Mixed seed intention!

(seeds out, watering can into backpack)

Then: Watering can intention!

(watering can out, seeds into backpack)

The watering can is still more than half full! The contents of the backpack all appear to be dry! Except for the inside of the watering can, which as already noted, is wet! But it seems important to spell things out when it comes to Oliver!

Quite.  The thing with the backpack has diminished some of Oliver's manic momentum, but he's still interested in planting those "mixed seeds", maybe a bit separate from his Parsnips Patch.

He wants to know how much the mixed seeds sell for before they're planted; whether he knows what they'll grow into before they're planted, or how much that will sell for; or if he knows what they'll grow into only after they're planted and maybe watered; if he knows, before or after planting, how long it'll take.

Oliver acquired the mixed seeds last night when cutting the weeds. Not all of the weeds yielded seeds, just one did. It's hard to tell what they're going to grow into; could be a number of seasonally appropriate things, and will take varying amounts of time to grow, depending on what they are. You can't sell mixed seeds.

Do the mixed seeds go into one patch, or several?  He's going to plant and water them and see when, at which stage, he knows anything more about them.

Just one patch. It's not obvious during the planting process what they actually are. They're planted and watered!

Oliver is such a dutiful farmer.

More like a brief manic high, but it's wearing off with nothing left to plant.

What's the price of wood, stone, fiber, if he can tell?  And is hay indeed 25?

Sell prices:

- Wood: 2G
- Stone: 2G
- Fiber: 1G
- Hay: 0G

Can he tell what the buying prices of those goods would be?

Buy prices:

- Wood: 10G
- Stone: 20G
- Fiber: not available for purchase
- Hay: 50G

Huh.  Interesting.  Not obviously patterned on the surface of things.

Next up, does he have anywhere obvious that acts as a storage container?  Besides the crate that turns things into money - oh, he'll check that crate to see what happened to the 1 small fish taco that Emily put there.

Oliver does not have any storage containers right now, but he could make a chest out of 50 wood, if he had 50 wood!

The shipping crate is now empty.

All right then.  He'll go inside his cabin and try to drop 1 wood on the floor there.

It takes a special sort of focused concentration to get just one wood, and then a different kind of mmph effort to drop it, but Oliver pulls it off. There is now one wood on the floor inside the farmhouse. Does Oliver linger near it?

He does not storm out of the cabin right away.  He is wondering, first, if he has any sense of writing materials--or maybe writing immaterials--such as might be used to compose a reply to Emily's letter.  There were questions in it, which hints at the possibility of answering her, though maybe she just had in mind their next physical meeting.

He isn't particularly trying to stay right next to the wood within the cabin, or keep his attention on it, though probably his mind does keep rounding every 5 seconds on the question of whether the wood will vanish.

The wood flies up off the floor and back into Oliver's hands, rejoining the stack of wood he was still holding from before.

There is no immediately obvious way to acquire paper, other than the paper Emily's letter was written on. That paper is blank on the back.

There is also no immediately obvious way to acquire ink, or a pen, or a pencil. Does Oliver perchance have one in his luggage that he brought from home?

He's got a pen if his luggage still exists.

...does Emily's salad recipe have a selling price?

Nope, you can't sell recipes.

And for that matter, Oliver is not entirely sure where that recipe notecard went, though he does remember what it said.

He won't complain about not being able to write and sell lots of recipe copies on strips torn off the back of Emily's letter, so long as the other means of obtaining money has not been turned off.

Oliver steps out of the cabin.  Does his luggage follow him and leap into his inventory now that he's, like, paying attention to that?

The luggage acts like ordinary mundane luggage from Oliver's former life!

One wonders what bizarre outlandish things Oliver will realize, over time, he managed to pack. One hopes they are not too bizarre or too outlandish.

Nothing world-breaking, he's pretty sure, unless a laptop or a laptop charger or a Kindle will do that.  He sort of hasn't been poking at thoughts about those items in case the world breaks them.

He hasn't avoided calling attention to the cellphone that was in his pocket.  Is it still there?  Does it have a selling price?  Or a buying price?

It is still there! So far we know that Oliver can use it as a timepiece or a torch. Oliver could sell it as a torch if he wants, for 5G. Cell phones are not for sale by anyone currently in possession of a cash register.

He figured.

Actually Oliver should've checked this before he looked at his cellphone, but does he automatically know the time even after putting the cellphone away?  ...can he tell that he knows the time from a mysterious source rather than from having just looked at his cellphone?  (Also, what time is it.)
