The video confirms Boeing will be taking advantage of the "commercial SLS" option in their lander bid, just as I've speculated:

Cross posting a link to the new Boeing HLS bid post, which currently has info/video on the engines and such:

Two industry Q&A logs:

Industry Q&A log 1, which has this interesting clarification about "SLS-derived commercial cargo vehicle"

Quote
19. Q: Can NASA provide SLS as GFE? If not, what does NASA mean in the BAA when it states that
Offerors could propose to use an SLS-derived commercial cargo vehicle solution; what is a
“commercial” SLS?

A: No, NASA cannot provide SLS as GFE. As provided in contract section H clause, Contractor Use
of Government-furnished Equipment, Property, or Information, while an Offeror may propose to
utilize GFE not otherwise listed in the solicitation, the use of such GFE is “subject to its
availability… and the Performing Organization’s ability and willingness to provide [it].” NASA has
assessed that the current manifest, funding levels, and schedules do not allow for the provision
of a GFE SLS flight for HLS use by 2024.

Further, as stated in section 4.4.3.5.2 of the BAA, Offerors are required to propose how they will
deliver HLS to the Moon using commercial launch vehicle(s). And while a commercial launch
vehicle approach does not prevent or preclude offerors from negotiating with the SLS prime
contractors directly to provide an SLS-derived commercial cargo vehicle solution for the Artemis
launch mission(s), NASA providing SLS as GFE is not a commercial launch approach as required
by the BAA.

Finally, as defined at 42 U.S.C. 18302(10), the term “Space Launch System” means the
government-owned civil launch system developed, managed, and operated by NASA to serve as
a key component to expand human presence beyond low-Earth orbit. Thus, by definition, SLS is
government-owned and not commercial. But as provided in BAA section 4.4.3.5.2, Offerors may
negotiate directly with the SLS prime contractors to propose the use of an “SLS-derived
commercial cargo vehicle solution” (emphasis added).

Industry Q&A log 2, where someone asked whether they can replace SLS/Orion with a commercial alternative, I wonder who could this be  ;)

Quote
44. Q: In 4.4.3.1. Technical Design Concept, NASA has referenced that HLS has to interface and
dock with Gateway or Orion for crew transfer. Can industry propose a commercial crew lunar
service that would provide an alternative crew vehicle to Orion that HLS can interface and
dock with? Will Orion (and the SLS launch of Orion) be considered as Commercial Service
similar to how the BAA addresses SLS for HLS?

A: Orion launched on SLS is NASA's crew launch baseline for Appendix H. For the 2024
demonstration mission, HLS must interface with Gateway or Orion. For 2026 missions and
beyond, interfacing with Gateway is required.

This actually has some interesting implications. Boeing, whom we know is bidding a lander to be launched on SLS, wouldn't be likely to ask this question. They wouldn't need to ask NASA to get them an SLS when they can build one themselves. So the fact that this question was asked at all suggests someone else was interested.

The rest of the answer is a nice clarification about what NASA meant by "SLS-derived." Seems to just be a bureaucratic word-dodge, i.e: "SLS is defined to be a government thing, so we can't call what you're using SLS, even though it totally is."

Not necessarily. Boeing is interested in using SLS doesn't mean they know what the RFP language would be like for allowing this, it's not like they're writing the RFP themselves (one would hope not). So it's entirely possible they're surprised by the RFP language just as you have been. Providing SLS as GFE would be much easier for Boeing than having to piece it together themselves and proving it won't affect government missions.

Continuing from previous summaries:
ConOps | Up/Down mass | Requirements Docs

From the BAA and Whitepapers:

* Contract timeline: Ten month base contract with multiple awardees. The firm fixed price of each Offeror for their respective initial landers would be set at this time. After those ten months, up to two contractors would be selected for Option A. Those contractors would then go on to finish development of their landers.  If two contractors are selected, one would perform its demonstration flight in 2024, the other in 2025.  Option B, the development of a more sustainable vehicle, would be selected two months after the Option A vehicle CDR, selecting only from the Option A providers.

Just adding a little bit to this (very good) summary, the BAA provides the following on the timeline and the number of contractors:

Quote from: HLS BAA
1.3 Human Landing System Acquisition Strategy

1.3.1 Acquisition Strategy Overview [...]

While NASA reserves the right to change its HLS acquisition strategy at any time, NASA is currently planning to award Base Contract Line Item Numbers (CLINs) to up to four contractors; exercise Option A CLINs for up to two of those contractors; and later exercise Option B CLINs for either one or two Option A contractors. NASA estimates that individual award values for this Appendix will be valued in excess of 1 billion dollars. Initial proposals to Appendix H shall include a firm-fixed-price (FFP) for the Base period and Option A period, and no price for the Option B period (to be priced at a later date). [...]

1.3.2 Overview of Contract Periods of Performance

To achieve a 2024 crewed HLS demonstration mission and a 2026 HLS demonstration mission that exhibits increased sustainability, NASA has structured this solicitation with the following discrete periods of performance that align with those objectives: 

Base period: Contract award through 10 months

-CLIN 001 – Base: 2024 HLS Design and Development. 2024 Design and Development, excepting long lead items. [...]

Option A period: October 2020 through 2024 flight demonstration.

[...] incorporation of a firm fixed-price for Option A at the time of initial contract award does not guarantee exercise of the Option A cited in the contract.

-CLIN 005 – Option A: 2024 HLS DDT&E and Demonstration Mission. 2024 mission Design, Development, Test and Evaluation and flight demonstration (excepting detachable docking adapter work, if proposed, to be performed under CLIN009). [...]

Option B: Approximately 2 months after 2024 HLS CDR through 2026 flight demonstration.

The 2026 sustainability demonstration mission is referred to as “Option B” throughout this solicitation. Unlike the Base and Option A CLINs, an Option B firm fixed-price will not be incorporated into the contract at the time of initial award.

-DDT&E for the 2026 HLS demonstration mission. Specific CLINs are to be determined at a later date.

As noted above, NASA anticipates exercising Option A for up to two contractors. NASA, at its sole discretion, will select one contractor to perform its demonstration flight first, in 2024, and one contractor to perform its demonstration mission in 2025. This may result in the second contractor incurring unforeseen expenses (e.g., storage, staffing, etc.). To accommodate this situation, NASA will effectuate any necessary contractual changes, as well as any corresponding requests for equitable adjustment [...].

1.3.3 Option B Scope of Work

To support increased sustainability after the 2024 demonstration mission, NASA anticipates funding the DDT&E necessary to evolve one or more contractors’ initial HLS designs for a 2026 flight demonstration of a sustainable HLS.

https://sam.gov/opp/7e3ad9e2ec964008a7f419ae8a8511a4/view

So NASA can start off with up to 4 contractors but 10 months later must downselect to up to 2 providers for Option A (under Option A, one provider will get a 2024 mission and the other provider will get a mission in 2025). For option B (sustainable HLS in 2026), NASA may decide to keep the same 2 providers or downselect to only one provider.  Jim Bridenstine has mentionned at a House hearing that he wanted to have 3 providers and then downselect to 2. But that may depend on funding.

P.S. Incidentally, the timeline for the awards hasn't been updated since February 10, 2020. It stills says:

Quote from: NASA (February 10, 2020 Notice)
The purpose of this notice is to post the following update:  NASA now anticipates that awards for the NextSTEP-2 Appendix H Human Landing System BAA will be made in late March or early April, 2020.

Awards should be in mid-April according to Jeff Foust:

Quote from: Jeff Foust
NASA is expected to announce [...] awards for human lunar lander study contracts, by the middle of April.

https://spacenews.com/nasa-planning-reorganization-of-human-spaceflight-directorate/

I am assuming that he means Appendix H of Nextstep (Human Landing Systems) will be awarded in mid-april since Appendix E (Human Landing System Studies) has already been awarded (see the post above).

Here is Boeing's dual SLS architecture presented in August 2019. The Ascent Element (AE, 10.9 t) and Descent Element (DE, 22.0 t) are launched on the first SLS and dock with Gateway in NRO. The second SLS launches the Transfer Element (TE, 9.2 t) with Orion. TLI payload is 43 t without Orion on Block IB. Co-manifest payload is 12.5 t with Orion.

Boeing's dual SLS architecture ... AE ... DE ... TE ...

Seems like Boeing is simply renaming the deck chairs, I guess since the deck chairs... errr... the "Elements" can't be rearranged?  And then they throw in some tonnages, and we're still no closer to actually landing on the Moon in 2024.
Sometimes I just flat out don't get it.

Well that's one way to sell another SLS.

I really don't feel this proposal has any advantage worth pursuing. It's still a 3 stage solution with all the development costs 3 elemetns require. 2 launches vs a max of 4 (if EUS wasn't seveloped and used) but still involves 2 docking/integration events to get the TE from Orion to the DE then Orion docks to the AE. No propellant transfer of  to the DE.... so what? Russia does it all the time on ISS.

The cabin is minimal, only 2 crew...

What is the architecture evolution?  Does this eliminate comanifested cargo on Orion for follow up flights or do they reuse the AE and the 2nd SLS launch is a new TE, DE and extra propellant?

They avoid rendevous of AE and DE on first mission but not on 2nd mission when new DE will be needed. I'm assuming 2nd mission will require SLS 1B to carry new DE and tanker to refuel AE and TE.

No advantage over competitors that are using commercial LVs. Relying on SLS 1B is huge disadvantage especially as it development could and most likely will slip given SLS history.

This stage I'm picking National Team as best option.

Here is what the paper says on the transfer element:
Quote
For the mission scenarios given in this report, the TE does the transfer to LLO burns to place the Lander into LLO, but it does not carry any return‐to‐NRHO propellant; it operates in an expendable mode. In other analysis (not included in here) the TE
carries the modest additional propellant needed for it to depart LLO, by itself and return to NRHO.

Rubio, Blumenthal Urge NASA to Expand Partnerships With Private Sector to Support Lunar Exploration Programs

Quote from: Senators Rubio and Blumenthal
Dear Administrator Bridenstine:
 
We write in support of the Artemis program and, in particular, NASA’s Human Landing System (HLS) program. Further, we write to highlight the importance of establishing repeatable, large cargo delivery services to the lunar surface to support the goal of developing a sustainable presence on the Moon.[...]

We urge you to proceed with the HLS acquisition as currently planned.

What could one infer from this letter? Is there some politics at play that’s delaying the HLS awards and Bridenstine possibly lobbied the pair of senators for this public show of support and urging to awards contracts?

I think your looking too deep into this, Rubio as a Senator for Florida (home of KSC) usually puts out a statement when a big NASA contract is being signed. Furthermore, he’s got the aerospace companies that are congregated around the Space Coast (Blue Origin, Boeing Space etc) whispering in his ear, so him sticking up for commercial space interests (like he does in this statement) isn’t unusual. Blumenthal is an odd one though, which aerospace conglomerate is based in Connecticut? Has he commented on space policy before? Whatever the reason for Blumenthal’s involvement, it’s nice to see senior figures from both sides of Congress acknowledge HLS’ importance as a program and support NASA’s current strategy for it. Bodes well for Artemis’ continued survival if a administration-change occurs.
