Phase 1: Incoming Protocol-Level Protection - Added MAX_LINES_PER_POLL = 50 constant to limit lines processed per poll iteration in irc_feed(), preventing burst flooding. - Added poll_lines_left counter to Session struct, reset each poll cycle. - Changed RateLimitEntry to track by user@host instead of nick, preventing trivial bypass via nick cycling. - Parse userhost from IRC prefix (nick!user@host) in irc_handle(). - Added violation tracking to RateLimitEntry for escalating penalties. Phase 2: Outgoing Message Throttling - Added OUTGOING_DELAY_MS = 100 constant for minimum delay between sends. - Modified net_send() with timestamp-based throttling using clock_gettime(). - Added 200ms delay between lines in !gitlog output (cmd_gitlog.h). - Added 150ms delay between AI response chunks (ai.h). Phase 3: Rate Limit Improvements - Increased RATE_LIMIT_MAX from 8 to 32 for larger tracking buffer. - Added TELL_DELIVER_MAX = 5 to limit messages per nick delivery. - Added AI_COOLDOWN_SECS = 5 to prevent rapid AI query re-submission. Phase 4: Command-Specific Fixes - Added rate_limit_check() to cmd_greeting_or_chat.h for casual chat. - Limited tell_deliver() to 5 messages per nick, excess stays queued. - Added 5-second cooldown after AI query completion before next query. Files modified: zynk.h, zynk.c, irc.h, net.h, ai.h, db.h, and all 19 command header files to pass current_userhost to rate_limit_check().

/*
|
|
* cmd_seen - Handle the "!seen <nick>" command.
|
|
*
|
|
* Looks up the given nick in the seen database and reports when they
|
|
* were last seen, in which channel, and what action they were performing.
|
|
* Special-cases: checking yourself returns "You are right here, duh!",
|
|
* checking the bot returns "I am right here!", and unknown nicks return
|
|
* "I have never seen <nick>". Rate-limited.
|
|
*
|
|
* Parameters:
|
|
* s - The IRC session.
|
|
* msg - The raw IRC message text.
|
|
* reply_target - Channel or nick to send the response to.
|
|
* src_nick - The nick of the user who issued the command.
|
|
*
|
|
* Returns: 1 if the command was matched, 0 otherwise.
