I reiterate the advice you've been given to save more now. You have basically all of your eggs in two baskets: your house, and your pension. Both of those things "feel" certain, but they're not. Some of us are old enough to remember when the CA real estate market was in the doldrums -- not just for a year or two, but more like a decade. While it is unlikely that will happen again, almost all of your own personal assets are betting it doesn't. And note that interest rates are already rising, which necessarily cuts into the affordability of already-unaffordable prices. So it is prudent to base your future planning on the assumption that you may not get as much from the house as you think you will.
As to the pension, last I heard, many CA jurisdictions are struggling with funding their pension obligations. I do not profess to be an expert in anything to do with CA. But over the past 4 decades or so, many folks who relied on pensions for retirement found themselves receiving less than they anticipated, or dealing with other benefit changes (e.g., maybe your lifetime paid medical insurance goes away even if the payment stays the same). Again, given how much of your retirement is based on the pension performing exactly as it is currently projected to, it is reasonable to look at the "what ifs" so you have a plan if the shit does hit the fan.
And this is where having your own 'stache of investments/cash can come into play. Sure, there's no guarantee the markets will perform well, either. But the more sources of income you have, the more likely it is that at least one or two will continue to provide what you need if/when the others go through a bad spell. Think of it like a chair, where the more legs you have, the more stable you are. Right now, you have the classic 3-legged stool of pension, SS, and home. That's awesome! You're definitely better off than the vast majority of people. But if you prop that up with a load of your own personal investments, now it's a chair, and is even more stable.
The other benefit of investing more now is that it habituates you to living on a slightly lower income. At worst, saving $$ now will tell you that you really want to maintain your current lifestyle, which tells you that you should plan to work longer if you find you need to (i.e., if your pension/home equity wouldn't be able to meet your current income when you want to retire). And at best, you find that cutting back on spending doesn't actually decrease your happiness, which means you don't need as much for the future, which means you can retire earlier on less.
Finally, you don't actually need to decide now. You have at least a decade to decide, and many, many things will change before that time comes, and the decisions you make now will have a major impact on where you are then. My recommendation is always to prepare to be retired at the earliest possible time -- meaning to save more now, so that if you hit 52 and are ready to go, you are in a position to do so. Then, if you hit 52 and your pension/home aren't paying out as much as you'd hoped, you have the flexibility to adjust your plan, because you have both cash (to cover you if you're ready to quit) and time (to continue working and build up the pension more if you're not willing to live on the reduced income).
