SCHK
Schwab 1000 Index ETF
stock NYSE ETF

I'd move the entire emergency fund into sgov. Shorter duration. I wouldn't bother trying to maximize returns on the emergency fund. Sure, you probably will do better with SHV with a rate cut, but you don't know that for sure and the whole point of the E-fund is you need to be able to cash out tomorrow without getting screwed if rates rise (however unlikely).
I'd replace sgov with Vangaurd's VBIL. Same duration but cheaper 0.06 ER. Saves you about $30 bucks per 100k. It's a free lunch every year so why not?
401k looks good.
Roth looks good too. One caveat; if you believe SCG is a drag, something to be avoided, you may want to snip the small cap tails off your core indexes and fully address them with Avantis ETFs. ie pair VOO or SCHK with AVUV instead of VTI.
The international allocation is light. But 20% is more than a lot of people. It's acceptable. Vanguard would recommend you double it to 40%. They are big on the classic investing ideas where P/E ratios matter. Lot's of people shit on Vanguard for "being wrong" on expected returns for the past several years. But loading up on value is not about winning today, it's about loading up the spring cheaply for several years and then experiencing an incredible era of out-performance when the spring is sprung.

Look to add SCHG, SCHK, SCHX. Think about pausing the single stocks and build those core etf positions. Echo the Roth IRA comments, max that thing out with the same/similar etfs. Saw that you’re also planning on getting out, you can roll your TSP into an IRA when you get out so also consider maximizing the match on your TSP until you get out. Good job, keep going.

Netflix, Meta, Amazon. Still DCA'ing into SCHK, DGRO, SCHD.
