The Beginning Stops at the End

Question

After a few minutes of thought, the password finally becomes obvious. You can sense your body shivering as you slide the letters into correct position with quivering fingers. The 'D' at the last slot slides into an 'E', and a creaking of intricate mechanisms welcomes you in. To your dismay, you find another door, waiting for two four-letter passwords to be entered.

$\qquad \;\;$

"Ugh, I should've known. It couldn't be that easy.", you groan. Looking around in utter despair, you spy a note lurking from one of the cracks. You pick it up; it reads:

Store cut into pieces confine chef rooster. Jump schusses heavens speaks pouches bag foot covering. Slide cut break cleaner immerse hose.

Can you crack the code once again?

Answer 1

I was almost there and had the same sequence as hexomino, but I have found the passwords. They are:

SHIP and DOCK

First part of the note:

Store: SHOP
cut into pieces: CHOP
confine: COOP (verb, as in "coop up")
chef: COOK
rooster: COCK

Second part:

Jump: SKIP
schusses: SKIS
heavens: SKYS ("skies")
speaks: SAYS
pouches: SACS
bag: SACK
foot covering: SOCK

Third part:

Slide: SLIP
cut: SNIP
break: SNAP
cleaner: SOAP
immerse: SOAK
hose: SOCK

Note that

each word in the three sequences is formed by changing one letter in the previous word.

Then note that

the first and last word are similar in each sequence, and changing one letter in each gives us a word that comes at the beginning of all three sequences. The only word that fits is SHIP, so SHIP is the first password.

The last word

could be various words: LOCK, ROCK, etc, but the title says "The Beginning stops at the End". If the beginning is SHIP, then the end must be DOCK (a ship stops at a dock).

EDIT: cleaned up

Answer 2

I think the answers are

Start here: SHOP
Finish here: SOCK

Reasoning

Each word or phrase corresponds to a four letter word and we connect one to the next by changing one letter. The second sentence needs to be read backwards to make the links work.
