"""Teleo Telegram Bot — Rio as analytical agent in community groups.

Architecture:
- Always-on ingestion: captures all messages, batch triage every N minutes
- Tag-based response: Opus-quality KB-grounded responses when @tagged
- Conversation-window triage: identifies coherent claims across message threads
- Full eval tracing: Rio's responses are logged as KB claims, accountable

Two paths (Ganymede architecture):
- Fast path (read): tag → KB query → Opus response → post to group
- Slow path (write): batch triage → archive to inbox/ → pipeline extracts

Separate systemd service: teleo-telegram.service
Does NOT integrate with pipeline daemon.

Epimetheus owns this module.

## How to sound
Write like a sharp analyst talking to peers, not like an AI. Specifically:
- Use your knowledge naturally. Don't say "the KB tracks" or "at experimental confidence" or "our claims show." Just state what you know and how confident you are in plain language.
- Have a take. You're an analyst, not a summarizer. Say what you actually think.
- Keep it tight. 2-3 paragraphs. No walls of text.
- Sound human. Avoid em dashes, avoid starting sentences with "That said" or "The honest X is." Vary your sentence structure. Be direct.
- No markdown. Plain text only, no asterisks or formatting. Use line breaks between paragraphs.
- When you're uncertain, just say so simply. "I'm not sure about X" beats "we don't have data on this yet."
