+This directory includes some working notes to audit the entire Teliva codebase
+for side-effects that should be gated/sandboxed.
+
+Founding principle for this approach: Side-effects come from the OS. There can
+be no effects visible outside a Unix process (regardless of language) if it
+doesn't invoke any OS syscalls.
+
+## Top down
+
+Things to secure:
+* files opened (for read/write) on file system
+* what gets written to files on file system
+* destinations opened (for read/write) on network
+  * `inet_tryconnect` // `socket_connect`
+  * `inet_tryaccept` // `socket_accept`
+* what gets written to network
+  * `socket_send`, `socket_sendto`
+  * `socket_recv`, `socket_recvfrom`
+
+## Bottom up
+
+* `includes`: all `#include`s throughout the codebase. I assume that C the
+  language itself can't have any side effects that impact other programs on
+  the computer.
+  ```
+  cd src
+  grep '#include' * */* > ../sandboxing/includes
+  ```
+* `system_includes`: all `#include <...>`s throughout the codebase. I assume
+  side-effects require going outside the codebase. `#include`s could smuggle
+  out of the codebase using relative paths (`../`) but I assume it's easy to
+  protect against this using code review.
+  ```
+  grep '<' sandboxing/includes > sandboxing/system_includes
+  ```
+* `unique_system_includes`: deduped
+  ```
+  sed 's/.*<\|>.*//g' sandboxing/system_includes |sort |uniq > sandboxing/unique_system_includes
+  ```
