I'm having ChatGPT compare to the prior version and they seem highly similar.

When ChatGPT isn't being lobotomized about a topic it's quite fun to interact with. e.g. You can give it a prompt like "i'm looking for whether the writer of the more recent doc has created a loophole for themselves to fail to deliver shares in the coming weeks" and it'll go all conspiratorial.

Take a look at "Equity trade Capture & Reporting". The items that stand out to me as being useable:

Although it is an unlikely event, NSCC will process and accept Shortened Settlement (T0 Same Day Settling) orders submitted prior to 1:30 PM ET, if Exchanges are closed

PCF stands for "Portfolio Composition File". So it sounds like if an exchange closed, the participant could submit their PCF file early (before in-the-money options are automatically exercised at end of trading day).

PCF files for the following trade date will be accepted or, ETF Agents/ Sponsors have the choice to allow NSCC to Carry Forward prior days PCF for Standard baskets only. NSCC does not carry forward Create, Redeem, Cash or Custom PCF’s, these basket types may be submitted in primary or next day supplemental cycle.

It sounds like this would allow participants to essentially submit their prior day's PCF file--again, this would be before in-the-money options were automatically exercised).

Both those loopholes become irrelevant if DFV exercises early.
