#
# The bot talks to the public on Twitter and calls tools (http_request,
# channel_send) driven by prompts built from user-controlled text. That
# makes it an injection target: an attacker can craft a mention that
# tries to override the instructions, exfiltrate system prompt fragments,
# or trick the bot into posting attacker-authored text.
#
# We run a cheap gate before the main classifier: if the tweet reads as
# an injection attempt, log it and don't reply. We deliberately use the
# bigger model (``gemma4:31b``) here because the cost of a false
# negative — posting attacker-controlled text on the public timeline —
# is much higher than the cost of a slower gate.
