This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1 · go to the accepted answer.
Post #57 describes the usual case. This is about the unusual one.
Visible particulate is a strong signal in the other direction: it is a reason to stop and ask rather than to filter and proceed.
That is what the documentation says. What happens in practice is usually close.

Clarity is a weak test. A solution can lose a significant fraction of its active content to degradation or adsorption while remaining perfectly clear.
Answering the question post #62 raises rather than the one it answers.

It reads as pedantry until the day it does not.

Second-hand, so weight it accordingly.

A guess, clearly labelled as one.
Everything in post #71 holds. The case it does not cover is the one I have.

Happy to be corrected if someone holds better data than mine.
Building on post #72 rather than restating it.
Temperature excursions in transit are common and are not all equal. A few hours warm is a different event from three days warm, and neither is visible in the vial on arrival.
That is the practical version. The rigorous version is longer and says the same thing.
Post #72 answers the question as asked. The question underneath it is different.

Adding it because I spent an afternoon working it out and nobody should have to twice.

Adding the measurement that post #79 says would settle it.

Happy to be the one who is wrong here if it settles the question.

Coming back to post #83, because the follow-up matters more than the original answer.
Visible particulate is a strong signal in the other direction: it is a reason to stop and ask rather than to filter and proceed.
Reporting the observation and leaving the explanation open deliberately.
Understood, and I withdraw the assumption I opened with.

Not the whole picture, but the part of it I can speak to.
