the 45 day limit driver is the crew module batteries but analysis is ongoing to add another 45 days
Did that ever get resolved?
Yes, they talked about how if the batteries are good during the first forty-five days, then the probability of degradation in the batteries during the second 45 days is the same as at the beginning of the first 45 days, so the batteries seem good to go for at least another month.

Yes: asked and answered during the press conference. the battery components (all the way down to the cell level) are monitored more or less continuously. Statistically, the battery as a whole Will continue to be usable for 45 days after the first failure occurs. Thus, the 45-day countdown is being continuously reset to "45" until that first failure occurs.

The impression I got was that the batteries are being evaluated on a regular (daily?) basis, and they've shown no degradation to date. So essentially, from a battery POV, the 45 clock resets with each evaluation.

NASA and Boeing continue working to increase their understanding of the Starliner spacecraft’s propulsion system before the return of agency astronauts Butch Wilmore and Suni Williams to Earth from the International Space Station. Teams are conducting ground tests at the agency’s White Sands Test Facility in New Mexico using a new Reaction Control System thruster previously planned for use on a future Starliner flight.
Wilmore and Williams provided an update Wednesday about their flight on Starliner and work aboard the space station during an Earth to space call. Following the crew news conference, NASA’s Commercial Crew Program Manager Steve Stich and Boeing Commercial Crew Program Manager and Vice President Mark Nappi spoke extensively about the mission and testing plans ahead of the Crew Flight Test return. Listen to a replay of the leadership briefing.
After an agency-level readiness review later this month, NASA and Boeing plan to select a new target return date for the Crew Flight Test. Following this review, NASA plans to host a televised briefing and will share more details on that when finalized.
Follow the commercial crew blog, @commercial_crew on X, and commercial crew on Facebook for the latest mission updates.

It was clearly stated and re-iterated in a (somewhat lengthy) response to the question. The conference is still available to replay on YouTube:

This is a bit of a misleading summary (nitpicking on the word
failure) and not really representative of how batteries work.
There is likely redundancy in Starliner for individual battery cells, sub modules, and full packs. However, if there was cell / module / pack
failure it could cause the pack to be immediate unusable, not start a 45 day clock.
Here is what was actually stated in presser:
We had set a certain risk level relevant for the batteries that was equivalent to about 45 days prior to the mission.
...
We look at the individual cells and how they're performing relative to each other and and if a cell or even a sub module in the battery had lower voltages or lower output, that could be an indicative of some kind of health issue relative to that particular part of the battery.
And so we get all this data on the ground. We've been watching it or the entire flight. And so we don't really see any degradation in any of the cells.
...
So when we look at that, you know essentially if you don't see any signs that the battery is degrading or any of the cells are degrading, then your risk level for any given day is the same therefore.
Distilling it down:
There is a range of acceptable voltages, internal resistance, pack output that are within the risk profile / level.
Since all the cells / modules / packs have stayed within the risk profile / level, we are at the same level of risk.

I get that the "the crew is stranded" narrative is a false one...
But is it safe to say the "vehicle has performed exceptionally well" also false?
Is the leak issue limited to the expendable service module or is it also in the main capsule?

And that's a better answer than Stich gave during the presser. See the previous press conference for Stich's better answer.
Is anyone else annoyed at the ignorant question by the Spectrum reporter about docking port availability? Waste of 2-3 valuable minutes, right there. (I'll show myself out.)

I thought that question a better use of time than reporters trying to nuance their way to get Stitch and Nappi to tell when Suni and Butch will be brought back, over and over and over.
I was really surprised when (I don't remember who) said that (paraphrasing) "we would rather have a gap between Crew 8 and Crew 9 than we would bring them home before we have a perfect answer for the thruster issue."
Really? And what if you *can't* replicate the problem?

The leak is in the service module. More specifically the thruster doghouse.

So what does this mean for the Dragon mission to rescue the stranded Starliner crew? Youtubers everywhere want, no need, to know (I'll see myself out 
)
There is no currently planned Dragon mission to "rescue" the Starliner crew. Wilmore and Williams are NOT stranded, as said clearly by Steve Stich during a past conference.

I can see no reason to not take NASA at its word. Wilmore and Williams are NOT stranded as implied by so many uninformed posters. Starliner is NOT stuck at the ISS. The mission IS being extended specifically to give the experts as much time as possible to monitor the situation with the thrusters and the helium leaks on the Service Module with the aim of gathering as much data as possible in order to better understand the dynamics of the anomalies, seeing as the Service Module won't be recovered for study. Wilmore and Williams WILL return at the mission conclusion in their own spacecraft, Starliner. The spacecraft itself is functioning properly and is not seeing anything that might be a cause for concern. There is no need for a rescue mission. Some people here need to take a chill pill and just enjoy watching the professionals guide the mission.

There is a bunch of pearl-clutching in some circles about the impact of grounding Falcon 9 on the "stranded" astronauts. It says something that these folks don't view this as evidence of the value of having two providers.

Astronauts Butch Wilmore and Suni Williams, crew members of NASA’s Boeing Crew Flight Test mission, performed a host of research activities and other roles aboard the International Space Station. Wilmore and Williams give the microgravity laboratory a complement of nine people working through daily tasks.
On Monday, Wilmore and Williams reviewed the procedures for using the Fluid Systems Servicer, which drains, purges, and circulates fluids on systems aboard the space station. Wilmore then refilled coolant loops in the water pump assembly located in the Columbus module. Tuesday saw the pair take turns during the morning pedaling on an exercise cycle while attached to heart and breathing sensors that measured their aerobic capacity. The duo then split up as Wilmore serviced a pair of research freezers that preserve scientific samples and Williams installed hardware on an experiment that explores atmospheric reentry and thermal protection systems.
The seven-member Expedition 71 crew joined the two Boeing Crew Flight Test astronauts to practice an emergency drill in collaboration with mission controllers. The teams aboard the orbital outpost and on the ground coordinated communications and reviewed procedures in the unlikely event of a pressure leak, chemical leak, or fire aboard the space station. Following that, Wilmore and Williams spoke to reporters from the space station, answering questions about their mission and the Starliner vehicle. NASA and Boeing managers also discussed the Crew Flight Test mission with the media in an audio teleconference afterward. Watch the crew news conference here and listen to the media briefing here. The duo also completed life support work refilling temperature loops with water in the Tranquility module’s internal thermal control system.
Advanced biology research also was underway aboard the orbiting lab on Thursday with astronauts exploring how living in space affects the human body and mind. Williams extracted DNA to identify microbe samples collected from station water systems. Results from the genetic biotechnology experiment may improve ways to keep crews healthy and spacecraft systems clean on future missions.
NASA astronaut Michael Barratt also assisted Wilmore, who spent all day servicing a pair of spacesuits in the Quest airlock. The duo cleaned the suits’ cooling loops and checked the communication systems ahead of a spacewalk planned for July 29.

Sorry if my humor was too subtle. It was a joke at the expense of the YT clickbaiters as well as the "Boeing can do no good/SpaceX can do no wrong" crowd.

With Falcon 9 grounded, it's not entirely out of probability that (should CFT's solutions be integrated fast enough on later Service Modules) that Starliner 1 could lift off. Wouldn't that be a thing to shush the overly-zealous SX fans?
Not likely, of course: ULA's busy trying to complete Vulcan certification, the second Starliner might be in pieces as it's readied/fixed/tested for S1, and S1's crew might be in a "Wait...what?" situation to fly so soon.
The whole point of CFT's emphasis on the "Test" part of their mission name is to avoid a "CFT-2." All else about the spacecraft's doing fine.

You mean to serve a crew rotation in place of Crew-9? Or just next spring in its normal slot? If it's to replace Crew-9, not a chance. Starliner may be fine to complete its mission, but there's going to be A LOT of reviews/findings/risk items that are going to have to be worked before NASA will certify it for crew rotations.
If you mean will it be able to work into its normal slot, that has a lot higher probability.
