@martingalloar & @codeHorse87 - I did some updates to the diag_* examples and fixed some bugs along the way. let me know if anything needs to be adjusted.

[randomstr1ng]

@martingalloar - done with checking all example scripts (as far as I was able to). Identified some issues in the core modules which are fixed now.

please review and merge if you do not see any other issues.

thank you!

hi @martingalloar ,

just want to check if we can merge the PR?

Thank you!

[martingalloar]

Sorry for the delay, I do have some additional/related changes in progress but we might want to split and break those down into a separate PR. let me do a final review on examples and we should be ready to merge!

[randomstr1ng]

no worries - I also do have some additional changes and bugfixes but those are related to the HoneSAP PR. I will also submit them in a separate PR.

thank you!

[martingalloar]

Pushed d826e13 with fixes for the Python 3 migration edge cases: strict SAPNI decoding restored, bodyless IGS HTTP handled, SAP Router route/framing covered, and example error handling hardened. Focused regressions pass; broader unit run still has the existing SAPRFCTHStruct round-trip failures.

[martingalloar]

@randomstr1ng whenever possible please check the changes I just pushed! Unless you see something off I believe it's in a very good shape now, and it's actually a great addition!

@martingalloar thank you for your enhancements and review. Looks all good on my end. So I think we can merge this and proceed with the next steps.
