• ✅ AddRecordWithOptions() for advanced enforcement creation
• ✅ Consistent enforcement reasons across moderators
• ✅ Maintains backward compatibility

6. Metrics and Tracking

• ✅ Tracks enforcement counts by type (kicks, suspensions, voidings)
• ✅ Records actions by rule category
• ✅ Daily metrics with unique user counts
• ✅ Notification delivery success/failure tracking
• ✅ Automatic cleanup of old metrics (90 day retention)
• ✅ Fixed unique user counting to properly handle save/load cycles
• ✅ Foundation for measuring player attrition vs enforcement visibility

7. Comprehensive Testing

• ✅ Unit tests for notification message formatting
• ✅ Tests for AddRecordWithOptions functionality
• ✅ Tests for notification status tracking
• ✅ Tests for public log privacy filtering
• ✅ Tests for metrics tracking
• ✅ Backward compatibility tests
• ✅ All existing tests continue to pass

8. Security & Code Quality

• ✅ Code review completed and feedback addressed
• ✅ Validation for edge cases (negative durations, etc.)
• ✅ Improved error messaging
• ✅ Privacy protections for moderator identity
• ✅ Access control considerations documented
• ✅ No secrets or PII exposed in public logs
• ✅ All review comments addressed

🎯 Impact

Player Transparency:

• Players now receive immediate DM notifications explaining enforcement actions
• Clear information about reason, duration, and how to appeal
• Enhanced /whoami makes it easy to check enforcement status

Moderator Tools:

• Standardized rule categories ensure consistent enforcement
• Metrics help identify patterns and improve moderation
• Public logs (when enabled) increase accountability

Privacy & Fairness:

• Moderator identity never disclosed in public logs
• Internal notes remain confidential
• Opt-in system gives guilds control over visibility

Educational Focus:

• Enforcement messages educate players about rules
• Clear expiry times reduce confusion
• /whoami prompt guides players to more information

<issue_title>Improvements to kick enforcement and notifications</issue_title>
<issue_description>### Summary

• Current kick enforcement displays only "Kicked from server," leaving
  players uninformed about specific reasons.
• Proposed enhancements include: DM/direct messaging, /whoami
  clarification, and detailed—but privacy-conscious—logging.
• Community feedback prioritizes player transparency, mod privacy,
  and fairness, suggesting public visibility only for action reason/
  duration.

Recommendations

• Extend enhancements to include a public "suspension/kick log"
  that records only reason and duration (no personal information).
  Store logs ephemerally (temporary/opt-in, no history).
• Improve visibility of /whoami and DM notifications; prompt
  players on Discord/game interface after enforcement.
• Focus log and notification changes on rule clarity—using enforcement
  records for education, not as public shaming.
• Streamline moderator UX: enable selection of rules as enforcement
  reasons (makes reasons objective/consistent).
• Never disclose mod identity or moderator notes in public logs;
  keep audit logs restricted for accountability.
• Measure effects: track player attrition and quitting in relation
  to log/notification visibility.

Suggested Issue Comment

Based on community feedback, recommend implementing a public
"suspension/kick log" displaying only enforcement reason and
duration (no player/mod identifiers), available to relevant linked
Discord or in-game users, and by default ephemeral or opt-in. Ensure
/whoami and DM notifications are highly visible following actions,
with clear prompts. Consider improvements to moderator UX—such as
selecting enforcement reasons from standardized rule list. These
changes aim to educate, not shame, increase rule transparency, and
mitigate mod abuse perceptions, while reducing confusion/toxicity.
Request tracking metrics for player attrition versus visibility
of logs/notifications.</issue_description>

The AffectedUsers field in DailyMetrics is marked with json:"-" so it won't be serialized to storage. When metrics are loaded from storage and deserialized, this field will be nil. However, at lines 143-146, the code checks if AffectedUsers is nil and initializes it if needed before using it. This means the UniqueUsersAffected count stored in the JSON will be preserved, but the actual set of user IDs will be lost after a save/load cycle. This could lead to undercounting unique users if metrics are loaded and then new actions are added, since the previously affected users won't be in the set anymore. Consider either serializing this field (with appropriate privacy controls) or recalculating the unique count differently.

[Copilot]

Fixed in commit 576ab46. Changed the logic to increment UniqueUsersAffected only when adding a new user to the session map, rather than recalculating from the map length. This preserves the stored count across save/load cycles while still tracking unique users accurately within each session. Added comments to document this behavior.

Changes applied in commit 576ab46. The metrics unique user counting has been fixed to properly handle save/load cycles by incrementing the count only when adding new users rather than recalculating from the length of the map. This prevents undercounting after a reload since the AffectedUsers map is not serialized.
