# EPF5 Dev Update - Week 15 ## Weekly Highlights Attended EPF5 weekly standup, office hours, and our in-house meeting which happens three times a week (Monday, Wednesday, and Friday). For this week, I continued adding tracing to the following folders: fork_choice_store, fork_choice_control, metrics, and slashing_protection. Here is the commit [link](https://github.com/Karrenbelt/grandine/commit/ef61fe838c8a471180e11c7c1b14f7b9d4290dee), which is currently tied to Karrenbelt repo. ![Screenshot 2024-09-21 at 23.20.15](https://hackmd.io/_uploads/Hylh_H-0pC.png) * An image showing what the tracing log output looks like. ![Screenshot 2024-09-21 at 23.21.55](https://hackmd.io/_uploads/BJbYHb0a0.png) I sent this to saulius so he can review and make any corrections if needed. Next week, I will continue with the tracing and also work on the fuzz script I'm writing, which is still a little messy at the moment.
