Morning is Karl's bay, needing to sabotage the fireworks and kill Harriet. From the start sprint left around the map hugging the edge, dropping under the bridge near Pick's apartment and then down towards the waterfront under the other bridges, then right until warehouse 2 is directly ahead. Tag the one guard who moves left of the warehouse (as their position is important to know for the escape) then follow behind them to the left of the warehouse, jump up onto the pipework, and follow this round over the top of the fireworks storage. Drop down, sabotage the fireworks, then use the hole in the side of warehouse 1 to sneak inside. Wait a moment for the eternalist on the warehouse floor to turn around, sprint across the entrance and jump up both balconies, then sprint around the top to the connecting gangway door into warehouse 2. From there jump up on the right hand side onto the roof beams, over the top of where Amador is hooked up, and in the back right corner there is a bottle next to a gun and some ammo. Throw the bottle into the laser mines on Harriet's window, which will probably alert one of the eternalists from inside Harriet's private area but hopefully shouldn't interrupt her speech. Wait for the eternalist to investigate the noise then head over the roof beams and get on top of the private room - take the bottle that is up there. Quickly drop down and hop into the private room through the window and hide in the corner. Make sure Harriet is tagged and wait for the speech to finish. The tag makes it easy to track her movement as she walks upstairs - there is a brief moment when she reaches the top of the stairs where she will be facing away from the entrance to her private room, which is when you can sneak out and melee kill her - the eternalist crouched looking at the wall won't notice. Move to the right and look down at the door - throw the bottle at the button to open it then back into the corner. Wait for the eternalists inside to stop investigating, then when they are turned away and the eternalist outside (who got tagged earlier) is turned away, drop down, go through the door and sprint away retracing the route to the exit.

But of course, on my final successful run, I then sprinted slap bang into an NPC Julianna mine! Julianna then triggered (there is a weird quirk in her NPC mines will be spawned in set locations before she invades?) so I had to quickly divert to hack the tunnels back open, which luckily is just left of the route back with some health I could pick up too. I then triggered another of her mines near Pick's apartment, but luckily neither alerted any eternalists and I didn't run into Juliana so I just about got away.
