With the black king on h7 Black’s position is also lost. 
1.Ke7 Ra6 (1...Kg6 2.Ke6 Kh7 3.Kf5+–; 1...Ra1 2.Ke6 Ra5 3.Kf5+–) 2.Kd7 g6 (2...Kg6 3.Kc7 Ra1 4.Kd6 Ra5 5.Ke6+–) 3.Kc7 Ra1 4.Kd6 Ra5 5.Ke6 Kg7 6.Rd8 Ra6+ 7.Rd6 Rxa7 8.Rd7+ Rxd7 9.Kxd7+–.

But triangulation doesn't work if black can pass, so perhaps Shankland's comment would have been correct with black's king on h7.

Oh dang, I take it all back. If black can pass then the pawn ending isn't lost either. 1.Rc8 Rxa7 2.Rc7+ Rxc7 3.Kxc7 Kf6 4.Kd6 g6 5.Kd5 "pass" 1/2-1/2

Somehow Shereshevsky's correct "This position or the position with the king on h7 is hopeless for Black. He loses the e5-pawn because of zugzwang." became Shankland's incorrect "Black would make a draw if he could pass here."

I agree with you 1.Rc8 wins. Incidentally white could have answered previous 56...Ra1-a5+ with 57.Kd5-c6 directly (choice of wins). 
Also your 1.Kc6 wins, e.g. 1...Kg6!? 2.Kb6 Ra1 3.Rb8.

With the black king on h7 can black draw without the move?

1.Kc6 Ra1!? 

or 1.Ke6 Kg6!? (not saying those actually draw)

but 1.Ke7 looks good because: 
1...Ra1 2.Ke6 Ra5 3.Kd6,
1...Kg6 2.Ke6 Kh7 3.Kd6,
1...g6 2.Kd6 Kg7 3.Rc8.

I didn't spend much time on it though, 
e.g. 1.Ke7 Ra6!? looks tricky.
There is also 1.Kc7 Ra1 2.Kc6 with similar triangulation ideas. But triangulation doesn't work if black can pass, so perhaps Shankland's comment would have been correct with black's king on h7.

In Theoretical Rook Endgames, 2023, P. 255, Sam Shankland surprisingly claims, that in the game Spassky-Torre after 57.Kd6  "Black would make a draw if he could pass here". But White wins easily by liquidation to a pawn ending via 1.Rc8 or 1.Kc6.

Spassky – Torre (1982)


D. 1

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

The central pawns here too (like in Carlsen-So, 2021, after 3...e5) are fixed (e4-e5). As will be shown later, the position of the black central pawn on e6 is more favorable, but even on e5, Black is usually able to make a draw. In the Spassky-Torre game, the passed pawn is not far advanced, and in the King's flank, the pawns are almost in their original positions. Therefore, different pawn setups are possible.

The game went as follows (in brackets are the marks given by Shereshevsky): 

35...Rd1+ 36.Kh2 h5 (?) 37.h4 (?) Rd2? 38.Kg3? Rd3+ 39.f3 Rd2? (?) 40.Ra8+ (?!) Kh7 41.a4 (?) Ra2 42.a5 f6 (?) 43.a6 Kg6 44.a7 Kh7 45.Kh2 Ra1 46.g3 Ra2+ 47.Kg1 Kg6 48.f4 Kf7 49.fxe5 fxe5 50.Kf1 Ra1+ 51.Kf2 Ra3 52.Ke2 Kg6 53.Kd2 Ra4 54.Kc3 Ra1 55.Kc4 Kf7 56.Kd5 Ra5+ 57.Kd6 Kg6 58.Ke6 Ra1 59.Kxe5 Kf7 60.Kf5 Ra5+ 61.e5 g6+ 62.Ke4. 1–0

In the analysis of the game, Shereshevsky believes that the e5-f6-g7-h5 set-up is definitely losing (Mikhail Shereshevsky, Endgame Strategy. The Revised and Expanded Edition of a Chess Classic. New In Chess 2022, p. 154). According to him, the move 36...h5 is a losing mistake because White wins by forcing Black to play f7-f6. After 37.Ra5 f6, according to Shereshevsky, White wins, pushing the pawn to a7. 

Shereshevsky's viewpoint is that, instead of 42...f6, Black can draw by 42...g6. This assessment is also wrong, because Shereshevsky assumes that with Black's pawns e5-f7-g6-h5 set-up pushing the pawn to the seventh rank does not win. This is not so, and with accurate play, White should win.

The following analysis demonstrates that 
1) The pawn structure e5-f6-g7-h5 of Black can remain viable if Black initiates proactive counterplay (as it is clear from the Carlsen-So thread), and 
2) after the result-changing error 37...Rd2? Black cannot save the game with 42...g6.


1) e5-f6-g7-h5 set-up

In the game, this setup occurred after 42... f6, when Black's position was already lost. However, before that Black had several opportunities to reach a draw with f6 set-up.

In the game after 35...Rd1+ 36.Kh2 h5 Spassky played 37.h4. Shereshevsky gives 37.h4 a question mark and claims that “White wins by 37.Ra5! f6 38.h4!”. But the position is drawn. 

D. 1 after 35...Rd1+ 36.Kh2 h5 37․Ra5 f6 38․ h4

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

Black has many ways to draw, for example, 38...Kh7 39.a4 Ra1 40.Ra7 Kh6 41.a5 g5 42.hxg5+ fxg5=. 

After 35...Rd1+ 36.Kh2 h5 37.h4 Torre`s move 37...Rd2? is a decisive mistake. Black throws away the draw which was possible by 37...f6 (D. 2) or 37...Kh7 (D. 3).   

D. 2 after 35...Rd1+ 36.Kh2 h5 37.h4 f6

37...f6 38.f3 Kh7 39.Ra7 Kh6 40.a4 Ra1 41.a5 g5 42.Ra6 (42.hxg5+ fxg5! 43.a6 Ra3 44.Ra8 Kg7 45.Kg1 Ra1+! 46.Kf2 Ra2+! 47.Kg3 Ra3=) 42...Kg7 43.Kg3 Ra3 44.Ra8 g4 45.a6 gxf3 46.gxf3 Ra2=.

D. 3 after 35...Rd1+ 36.Kh2 h5 37.h4 Kh7

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

38.Ra7 f6 39.a4 Rd4 40.f3 f5! 41.exf5 Rxh4+ 42.Kg3 Rf4!=. 

In the game Spassky played correctly 41.a4 which wins (other winning moves are 41.Ra7 and 41.Kh2). Shereshevsky gave this move a question mark and 41.Ra5 an exclamation mark, but this is the wrong way round. 

D. 4 after 35...Rd1+ 36.Kh2 h5 37.h4 Rd2? 38.Kg3? Rd3+ 39.f3 Rd2? 40.Ra8+ Kh7 41.Ra5

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

After 41.Ra5? Black draws by 41...f6! 42.Ra8 Ra2 43.a4 g5 44.a5 Kg7 45.a6 Ra3! (cf. thread Carlsen-So (2021), D. 3-2 after 7...Kg7!) 46.a7 g4!=.   

As we have seen, in the D. 1-4 Black was able to implement the straightforward plan Kg8-h7-h6 followed by g7-g5. In some lines Black could also implement the g6-f5 plan. 

Back to the game after 37.h4.

D. 5

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

This is the game position after 37.h4. 

37...Rd2? 38.Kg3? 

These are result-changing errors yet neither the players nor Shereshevsky take notice of them.
With the rook on 1. rank which reduces severely the mobility of the white king, Black could without any problem implement the Kh7-h6 and g7-g5 plan. 
After 37...Rd2? White could have won by 38.Ra8+ or 38.f3. 

38...Rd3+ 39.f3 Rd2?   
Black voluntarily abandons its optimum position on the third rank and throws away the draw which was possible by 39...f6 or 39...Kh7.   

40.Ra8+ Kh7 41.a4  

See notes to D. 2. 

41...Ra2 42.a5 f6   

The decisive mistake according to Shereshevsky but the position was already lost. Shereshevsky's recommendation of 42...g6 also loses (see D. 7). 

D. 6

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

If the rook were on a3 (see note to 39...Rd2?), Black would draw by g5. 

43.a6 Kg6 44.a7 Kh7 45.Kh2 Ra1 46.g3 Ra2+ 47.Kg1 Kg6 48.f4 Kf7 49.fxe5 fxe5 50.Kf1 Ra1+ 51.Kf2 Ra3 52.Ke2 Kg6 53.Kd2 Ra4 54.Kc3 Ra1 55.Kc4 Kf7 56.Kd5 Ra5+ 57.Kd6 Kg6 58.Ke6 Ra1 59.Kxe5 Kf7 60.Kf5 Ra5+ 61.e5 g6+ 62.Ke4. 1-0. 


2) e5-f7-g6-h5 set-up


D. 7

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

Instead of 42...f6 played by Torre Shereshevsky suggested 42...g6: "Correct was 42...g6!, after which the play carried out by Spassky in the game would not have given White any chance of success. He would not have succeeded in creating a passed pawn on the e-file". However, as we shall see, this move also cannot save the game.

43.Ra7!

White must prevent f7-f5. 43.a6? f5! 44.Kh2 Ra1! 45.a7 f4! 46.Re8 Rxa7! 47.Rxe5 Kg7 48.Rb5 Ra1 49.Rb4 Kf6=.

43...Kg7 44.a6 Kf8 45.Ra8+ Kg7

D. 8

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

46.Kh2!

46.a7? is here premature and allows Black to draw by 46...f6!

D. 8-1 Variation 46.a7? f6!

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *

46.Kh2 Ra1! 48.g3

D. 8-2

* * * * * * * *

* * * * * * * *
* * * * * * * *

48...Ra2+! 49.Kg1 g5= or 49...Ra1+ 50.Kf2 g5 (50...Ra2+ 51.Ke3 Ra3+ 52.Kd2 g5=)․ 

After 46.Kh2! (D. 8) Black has several tries, but all does not help. 
 
Back to the main line, D. 8. 

46...Ra4

46...Ra4 aims to prevent 47.g3, because after 47...f6! White can not respond with 48.f4. 

If 46...Ra1, then the only way to win is 47.g3. After 47...f6 the simplest way to win is 48.f4 exf4 49.gxf4+–.   

The plan f7-f6 and g6-g5 plan does not succeed, because with the White's pawn on g2 Black is unable to create a passed pawn (cf. the line 46...Ra4 47.g3? f6! 48. 48.Kg2 g5). 46...f6 47.Kg1! g5 48.hxg5! fxg5 49.a7! g4 (49...h4 50.Kf1 Kh7 51.Ke1+–) 50.fxg4! hxg4 51.g3+–. 

D. 9

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

47.a7!

The only winning move. Here 47.g3? is a fatal mistake: 47...f6! 48.Kg2 g5 49.Kf2 Ra2+ 50.Ke3 Ra3+! 51.Ke2 Kh7! 52.a7 gxh4 53.gxh4 Kg7 54.Kd2 Ra2+ (54...Kh7? 55.Rf8! Rxa7 56.Rxf6!+–) 55.Kc3 Ra1=. 

47...Ra2 48.Kg1 Ra1+ 49.Kf2 Ra2+ 50.Ke3 Ra3+ 51.Kd2 Ra2+ 52.Kc3 Ra3+ 53.Kb4 Ra2 54.Kc5 Kf6 55.g4 

White advances his pawn to g5 and at the appropriate moment exchanges his passed pawn for the Black pawn on f7. 

55...Kg7 56.g5 Ra3 57.Kd5 Ra5+ 58.Kd6 Kh7 59.Kc6 Ra1 60.Rd8 Rxa7 61.Rd7! Ra6+ 62.Kb5 Ra1 63.Rxf7+! Kg8 64.Rf6! Kg7 65.Kc5+–.
