Q: Swapping eggs puzzle (parity?)

Q: The Last Challenge

Infinity MilestoneThis question is a continuation of this one, and you might want to read it if you haven't already. 'Another code-name,' I think. 'There's no way that's his real name'. Nonetheless, I type in 'ANONYMOUS' and the other monitors immediately blank out. There is no light left in the room except the li...

Feb 8 at 23:04, by bobble
If a post is low-quality and should be deleted (e.g. breaks rules or is a blatantly worse duplicate answer), please don't just edit in LQP to add spoilers. It doesn't fix the fundamental issues.
Clicking the "Edit" button means you're saying "I can make this a completely acceptable answer, by our standards, with an edit". If the answer is unacceptable for its content, then adding spoilers does nothing to fix the content

Q: Dirac notation for English

Mariia MykhailovaDirac notation is very expressive: now only does it allow to write quantum states and operations more concisely, it can be used to shorten written English words and phrases! Here are some examples: What is shown on the hidden photo?

Hey everyone! I'm currently finishing up the first draft of my FTC entry puzzle, and I would really appreciate if someone could help look it over before I post it and before the challenge window closes. If I don't get a response in the next 4-5 hours or so, I'll just post it directly
 
If that doesn't work, you can also bribe the bot so it happens to malfunction and update a few hours later :P

@msh210 yes
crossword progress: 103/180
 
I have a quarter-baked idea about the C4 and would like at least a few minutes to contemplate it futilely before getting a further hint.
 
What is the idea baking in?
 
(For the avoidance of doubt, almost certainly there's nothing to it.)
@bobble Cerebrospinal fluid, I guess?
Well, if my idea had any actual merit I've been unable to find it. No longer contemplating it now.
 
9:19 PM
@Jafe exciting!
 
10:04 PM
@GarethMcCaughan My favorite marinade.
C4 hint 2: "King" appears at the start of the clue for a good reason.
@Jafe Looking forward to it.
 
That hint kinda fits with some of my quarter-baked pseudo-semi-pre-ideas.

Q: This escape room sucked! Did I do something wrong?

HTMSomeone told me that I should put a link to Fortnightly Topic Challenge #50: Escape Rooms... whatever that is, I guess. PSE, I need your help.
