If the noise has shown up coincidentally with your riding on the first few truly warm and humid days this year in your area, I'd look for aluminum-on-aluminum "twinning," a term I learned from a materials engineer, if only to eliminate that possibility. Creaking comes and goes when it turns warm and humid around here with my aluminum handlebars and aluminum stems on various of my bikes.

Titanium bikes certainly aren't indestructible. But, I am also leaning towards a wheel problem from your description. It doesn't hurt to inspect the whole bike from seat to cranks.
Do you have a spare wheelset that you can try?
That likely eliminates many of the fatigue related issues mentioned above.
I've had wheels that I've built up pop and ping for a while before settling down. And, I've wondered if it was due to spoke windup. Perhaps uneven spoke tension. The oil mentioned above might help.
You might true the wheel, even out the spoke tensions, and try to find a neutral position for the spoke nipples.
If you had a good local wheelbuilder, the person might be able to inspect and touch up the wheels a bit.

One of the first wheels I built made strange noises - that stopped after the first ride in the rain. I think it was the spokes at the crossing.

Is this a disc brake bike? The symptoms are exactly what happens when a disc brake rotor is slightly out of true, especially since it goes away when you lean to one side.
BTW - I'll have to tell my friend that the cracked frame that he sent back to Lynskey was supposed to be indestructible.

In that case, the spokes might be settling and the builder may not have de-stressed them completely. Check the tension/true regularly and maybe get them adjusted after 1,000 miles.

the rotor is going to be held in position better than the wheel's rim. However, if the caliper assembly is not installed as it should be/not secure, the frame may allow for enough localized brake area to flex. The frame tweaking could result in the pads to skim the rotor intermittently.
Check the caliper assembly's mounting hardware for witness marks as evidence for movement.

With disc brake the hub cold be loose and with your weight on it, cause the disc to rub. When the disc and pads heat up they will expand causing contact. The pads do not wear out evenly, could be one pad has more material and when you lean or turn, causes rubbing.
In the end, I'm guessing the brakes

I’m also guessing rotor. When you turn a bike things get a little cross loaded. I have a brake noise on my MTB that only appears turning.
Worse with one sided mechanical calipers because you usually adjust them pretty close.
Or maybe it’s something stuck in the tire
