I think the key points in your post here are “rightly or wrongly”.
Could you give some examples of how the “declassification process is quite unclear”
Could you explain the “leeway” that a former President has in deciding which classified documents to declassify and how he does it. What are the constricting factors? What are the various ways that a former President can declassify classified documents?
I mean, there must be some established regulatory procedures on these points and you seem to be very familiar with them. I’d be genuinely interested to know.
A former president cannot declassify anything. A currently sitting presdient can but there are well documented procedures to do so.
Former President Donald Trump claimed this week that he had the authority to declassify documents just by thinking about it. While presidents have broad authority to declassify material, but there is a detailed process unlike what Trump described. Here's a look at how declassification works.

There's also a detailed process for declassification with rules laid out under executive order. Typically, if a president wants to declassify something, he checks with the agency in charge, which has broad say in whether the information becomes public, Gerstell said. If documents are declassified, there’s usually a painstaking process of blacking out what information still stays secret. “It’s not a question of a concept being declassified, or boxes of documents. It’s a word by word determination,” he said.
The declassification order must be memorialized and any agencies that are affected have to be notified, Moss said. The individual documents then have to be re-marked to show they’re no longer considered classified.“It’s not clear what Jedi-like lawyers said that you could declassify things with a thought, but the courts are unlikely to embrace that claim,” said Jonathan Turley, a George Washington University law professor who was a Republican witness during the first impeachment proceedings against Trump in 2019.
The Justice Department has said there is no indication that Trump took any steps to declassify the documents seized from his Florida home.
