Phase 5 — Security, Privacy & Power Update: HYBRID COMMANDS - Main command group converted to hybrid_group (slash + prefix) - All commands work as both /wh and [p]wh CONTEXT MENU ACTIONS (right-click) - Report to Wormhole — opens modal for report reason - Wormhole Bookmark — saves message to DM - Wormhole Delete — staff can delete from entire network - Wormhole Profile — view user stats across networks GRANULAR MENTION POLICY - Per-network control: allow/block @user, @role, @everyone, @here - Per-server overrides (different rules per guild) - Per-user exemptions (trusted users bypass policy) - Replaces legacy strip-* with proper policy engine - wh mentions set/server-set/exempt/unexempt/status TERMS OF SERVICE / RULES ACCEPTANCE GATE - wh tos enable — require acceptance before messaging - Built-in legal template (6 sections, prosecution-ready) - Consent tracking with timestamps - wh tos set (custom text), template (reset), accepted (view), reset (force re-accept) - wh accept / wh agree — user-facing acceptance flow - Blocks relay for non-accepted users with helpful reminder MOD EDIT/DELETE ACROSS NETWORK - wh mod edit <name> <msg_id> <new_content> — edits all relayed copies - wh mod nuke <name> <msg_id> — deletes from every server + original - Both audit-logged REPORT SYSTEM - wh report message — report via reply or message ID - Context menu report with modal (reason input) - Anti-abuse cooldown (60s between reports) - Content hashing for audit trails - Reports sent to log channel + network owner DM - wh report list/resolve/action (ban/mute/warn/dismiss) - Capped at 200 reports per network PRIVACY & SECURITY - _ReportModal class for context menu reporting - Content hash stored instead of plaintext in report records - Report cooldowns prevent abuse - ToS acceptance with ISO timestamps for legal compliance 4,196 lines in wormhole.py, 419 in utils.py — 85+ commands total
