+"""T05 — RAG Citation Validator.
+
+Per RMIV5 §T05 (G05 FIX). After an LLM generates a report section from
+retrieved RAG chunks, every claim in the output must cite a source by
+number [1], [2], etc. This module enforces that.
+
+Pipeline:
+  1. LLM produces text constrained to retrieved chunks (in generator.py)
+  2. This validator parses every [N] citation in the text
+  3. Verifies that:
+     a. N is a valid index into the retrieved chunks list
+     b. The cited sentence/paragraph is supported by source N
+        (substring match on key terms)
+  4. Returns a citation report:
+     {
+       "validated_text": str with unciteable claims replaced by
+                        "[Data not available]" or removed,
+       "citations": [{"claim": str, "source_idx": int, "source_text": str}],
+       "unciteable_count": int,
+       "validation_rate": float  # 0.0-1.0
+     }
+
+Why this exists:
+  Reports that hallucinate destroy trust. Every claim in a $5 report
+  must be backed by a source we can show. If we can't find support,
+  we say so — explicitly — rather than fabricating.

+"""T12 — CertStream phishing domain monitor (G04 FIX adjacent).
+
+Per MINIMAX_M3_TASKS.md T12. Watches Certificate Transparency logs in real
+time for domains that spoof crypto brands (MetaMask, Ledger, Coinbase,
+etc). When a match is found, fires a Telegram alert via the existing
+bot and persists the domain to Postgres `threat_domains`.
+
+Run as a background task in lifespan.py. If CertStream is down, log and
+continue — never break startup.
+
+Why this matters: phishing sites clone crypto brands and steal wallet
+seeds. CT logs show new domains BEFORE they go live, giving a 48h lead
+time to take them down.
+
+Usage:
+  from app.domain.threat.certstream_listener import start_listener
