Couple of technical things. Some of this is probably hard to reproduce locally since you need a bunch of Drydock/Harbormaster config or other weird custom stuff to activate some of the sections. I can likely tweak anything you can't easily sort out -- I think it's all pretty simple, just hard to get the elements to show up.

• I think we should leave active landing operations on top, they seem pretty important? This element should only be visible when it's highly relevant (active operation ongoing, or failure) so I think it's OK to let it stay up top?

• "Related changes affecting these files" has lost a header/box:

• "Unit Tests" table is getting some weird header stuff since it's still and old-style box:

• Custom revision header warnings no longer work. Here's master (warning provided by a custom field):

...but it's gone in this patch:

• I'm getting this stack trace locally, not sure what the root cause is. I can chase it down:

• These elements looks a little odd, particularly with the margins (probably not new):

• The "Z" key ("haunted comments") isn't working for me.

Product/design stuff:

• This feels good to me overall, doesn't seem weird or anything. Like Diffusion, I think we can probably refine some stuff, but big picture feels totally reasonable.
• Author in sidebar is maybe weird on revisions, which are strongly-authored to me, but this is a general question we have a little bit of product tension on across all the new stuff. I don't think we need to resolve it immediately.

• Landing operations now on top
• Legalpad Warning now correctly spaced
• Moved author to Subheader
• Remove 'noBox' from Recent Similar Revisions
• Unit Test have better headers
• Revision warnings should appear

not sure about haunt mode or that error_log.

• remove wrap_id? can't find what this does

Blame indicates it went with arc_project which doesn't exist anymore.

This is ready for re-review

I'll figure out what's up with that error log, one sec..
