Label: reading notes for pwntools-demo.py and owned-hello.c.
Do not install pwntools for this page. Neither file was run. No pipe bytes were captured.

What the documentation supports, from the pages read:
- The stable introduction identifies itself as pwntools 4.15.0 documentation.
- It shows `from pwn import *` and says the library is a large toolkit.
- It says interacting with processes uses pwnlib.tubes.process.
- The process page says process() spawns a new process and wraps it for communication.
- The introduction's examples call sendline and recvline. Those examples are not this course's files.

What this course's files do, as source:
- owned-hello.c reads with fgets into an 8-byte array, then prints hello-from-owned if the read succeeds.
- The Linux fgets(3) page says fgets reads at most one less than the size it is given and stores a terminating null.
- pwntools-demo.py would start ./owned-hello and send the line desk. This note does not include captured pipe bytes. The script closes without receiving a line, so its source does not establish an observed greeting.
- A source trace, not a captured run: if fgets succeeds, the C file prints hello-from-owned.

What the primer does not do:
- It does not grant permission to start a program.
- It does not find a bug, change a mitigation, or finish a challenge.
- It does not include a setting that turns randomization off. The process page documents such a setting. This file does not use it, and this course does not ask you to.

Stop conditions if a later install is allowed on a machine you control:
- Stop if the program is not the owned hello you just built.
- Stop if you are about to change a host mitigation or a kernel policy.
- Stop if the platform forbids publishing what you did, and you were about to post it.
