Rules:
- The messages can go as far back as the beginning of the 7 day period (the moment you found out about your assassin is after you)
- You can only send the messages if you have cell signal (maybe don’t hide in the woods, you assassin might be there, and you don’t get a do-over 🙃)
- Your phone is immune to damage and malware (although spyware and keyloggers can still be on there, but they can’t affect the system, just on “read only” mode). Auto-updates are now disabled by default
- If assassin got your phone, they could send false messages to trick your past self. (Don’t lose your phone!)
- At the end of 7 days, the Assassin will just drop dead due to time travel limitations, time travelers cannot survive longer than 7 days in the past (yes, the assassin is a time traveler 😉)

What time travel rules? See: https://tvtropes.org/pmwiki/pmwiki.php/Main/TemporalMutability
Going with “overwriting the timeline,”
buy yourself an hour to live on the first day, should be easy enough
make fat cash with options trading in minutes
buy hella security
repeat until the seven days have passed
I would also rig a “dead man’s switch” on my phone in case the assassin ever does get me, to reset things (by telling my past self of my current situation, so they can avoid it).
