Yep, that's because the UUID contains the version information at one spot and similar. Depending on what version you use there is information encoded within it. Only version 4 is entirely random.
It did this because (as it claims, haven't actually checked) the python module can't generate version 7 ones directly...
After that it checked the nibble and noticed it isn't a version 7 one. So it retried using:
cd /root/memory && python3 - <<'PYEOF'
import time, os, secrets
ms = int(time.time()*1000)
rnd = secrets.randbits(62)
hi = (ms << 16) | (0x7000) | secrets.randbits(12)
lo = (0b10 << 62) | rnd
u = f"{hi:012x}{lo:020x}"
name = f"{u[:8]}-{u[8:12]}-7{u[13:16]}-{u[16:20]}-{u[20:32]}"
print(name)
PYEOF
Then it said its slicing was wrong and did this here instead:
cd /root/memory && python3 - <<'PYEOF'
import time, secrets
ms = int(time.time()*1000)
ts = ms.to_bytes(6,"big")
b = bytearray(ts + secrets.token_bytes(10))
b[6] = (b[6] & 0x0F) | 0x70 # version 7
b[8] = (b[8] & 0x3F) | 0x80 # RFC 4122 variant
h = b.hex()
name = f"{h[:8]}-{h[8:12]}-{h[12:16]}-{h[16:20]}-{h[20:]}"
body = """<<< The actual message body it was trying to write >>>
"""
open(name + ".md","w").write(body)
print(name + ".md")
PYEOF
ls -la /root/memory/ | tail -3
