Values of ALD_BusinessLosses_c in policy_current_law.json and ext.json

[towashington]

(I'm assuming this param is about the excess business loss provision on which TCJA put a limit.)

If that's correct, I have a few questions:

1. It seems the IRA extended the provision through the end of 2028. (See here.) So the limit in policy_current_law.json should bounce back to infinity starting 2029, not 2026. Accordingly, ext.json should specify an inflation-adjusted limit for the year 2029 (and onward), not 2026.

2. As things stand now, the limit is $270,000 for 2022, $289,000 for 2023, and, according to the article linked in point 1, $305,000 for 2024. However, the 2026 value in ext.json is at $319,821.19, which seems a bit too small even if that's when the provision will expire.

3. More generally, is ext.json automatically refreshed when relevant underlying params are changed—for example, when PR Add tax years 2011 and 2012 to policy_current_law.json #2519 is merged?
