Even with the prompt firewall (username vs content), the LLM can still
occasionally mis-apply a content-level zero-tolerance flag (sara /
conflict_instigation) to a message whose ONLY violation is the username
(e.g. 'matikanetanyahu'). The auto-delete eligibility check only recognized
exact offensive_username flags, so such false positives still deleted the
message.
Add a belt-and-suspenders guard in isNicknameOnlyViolation: if the flag set
is entirely username-attributable (offensive_username/sara/conflict_instigation)
AND the analysis text corroborates that the violation is username-only with
clean message content, route to nickname-reset instead of message deletion.
Adds 6 test cases covering the real matikanetanyahu scenario and the
false-positive/negative boundaries.
When the ONLY violation is offensive_username (message content clean):
- Message is NOT deleted (nickname-only violation bypasses auto-delete)
- Member's server nickname is reset to default username via
setNickname(null) (Discord shows the global username again)
- Action 'reset_nickname' logged to moderation_actions; cooldown
10min per guild:user (LRU) so repeated messages by same member
don't hammer the Discord PATCH
- Config: AUTO_NICKNAME_RESET_ENABLED / AUTO_NICKNAME_RESET_COOLDOWN_MS
