# demo-save-load.sh — PoC harness for the "persistent sandbox" video beat.
|
|
#
|
|
# Flow (see docs/demo-save-load-poc.md):
|
|
# session A: /sbx launch docker → /ai start → /grant oracle →
|
|
# /ai oracle !build fib.py & run it → /sbx save buildbox → quit
|
|
# prove: container purged on quit, but hh-snap:buildbox image survives
|
|
# session B: fresh client → /sbx load buildbox → the model's code is intact
|
|
#
|
|
# Headless: drives the ratatui client over tmux send-keys, asserts via
|
|
# capture-pane + `docker exec`. PoC/correctness first; feeds video-toolkit later.
|
|
#
|
|
# Usage: hh/demo-save-load.sh [--keep]
|
|
# --keep leave the server, container, image and tmux sessions up afterwards
|
