What needs review:

• My changes to ./development/internal_api.md - I did a minor text formatting change, and I added a line acknowledging the 50 second limit. Is there another place / way I should be providing this info?
• Code examples exist in ./administration/logs.md, ./administration/troubleshooting/log_parsing.md I'd appreciate a quick check by an engineer to see if the response formats need an update.

Reassigning to @sean_carroll for review. @m_gill, thanks for pinging me!
