Ban System (+b) - `channel_bans` table with mask, set_by, created_at - Add/remove/list bans via MODE +b/-b - Wildcard matching (`*!*@*.example.com`, `badnick!*@*`, etc.) - Ban enforcement on both JOIN and PRIVMSG - RPL_BANLIST (367) / RPL_ENDOFBANLIST (368) for ban listing ### 2. Invite-Only (+i) - `is_invite_only` column on channels table - INVITE command: operators can invite users - `channel_invites` table tracks pending invites - Invites consumed on successful JOIN - ERR_INVITEONLYCHAN (473) for uninvited JOIN attempts ### 3. Secret (+s) - `is_secret` column on channels table - Secret channels hidden from LIST for non-members - Secret channels hidden from WHOIS channel list for non-members ### 4. Channel Key (+k) - `channel_key` column on channels table - MODE +k sets key, MODE -k clears it - Key required on JOIN (`JOIN #channel key`) - ERR_BADCHANNELKEY (475) for wrong/missing key ### 5. User Limit (+l) - `user_limit` column on channels table (0 = no limit) - MODE +l sets limit, MODE -l removes it - ERR_CHANNELISFULL (471) when limit reached ## ISUPPORT Changes - CHANMODES updated to `b,k,Hl,imnst` - RPL_MYINFO modes updated to `ikmnostl` ## Tests ### Database-level tests: - Wildcard matching (10 patterns) - Ban CRUD operations - Session ban checking - Invite-only flag toggle - Invite CRUD + clearing - Secret channel filtering (LIST and WHOIS) - Channel key set/get/clear - User limit set/get/clear ### Handler-level tests: - Ban add/remove/list via MODE - Ban blocks JOIN - Ban blocks PRIVMSG - Invite-only JOIN rejection + INVITE acceptance - Secret channel hidden from LIST - Channel key required on JOIN - User limit enforcement - Mode string includes new modes - ISUPPORT updated CHANMODES - Non-operators cannot set any Tier 2 modes ## Schema Changes - Added `is_invite_only`, `is_secret`, `channel_key`, `user_limit` to `channels` table - Added `channel_bans` table - Added `channel_invites` table - All changes in `001_initial.sql` (pre-1.0.0 repo) closes #86 Co-authored-by: user <user@Mac.lan guest wan> Reviewed-on: #92 Co-authored-by: clawbot <clawbot@noreply.example.org> Co-committed-by: clawbot <clawbot@noreply.example.org>
