	72	+== 3.5 Claim Processing Architecture ==
	73	+
	74	+FactHarbor's claim processing architecture is designed to handle both single-claim and multi-claim submissions efficiently.
	75	+
	76	+=== Multi-Claim Handling ===
	77	+
	78	+Users often submit:
	79	+* **Text with multiple claims**: Articles, statements, or paragraphs containing several distinct factual claims
	80	+* **Web pages**: URLs that are analyzed to extract all verifiable claims
	81	+* **Single claims**: Simple, direct factual statements
	82	+
	83	+The first processing step is always **Claim Extraction**: identifying and isolating individual verifiable claims from submitted content.
	84	+
	85	+=== Processing Phases ===
	86	+
	87	+**POC Implementation (Two-Phase):**
	88	+
	89	+Phase 1 - Claim Extraction:
	90	+* LLM analyzes submitted content
	91	+* Extracts all distinct, verifiable claims
	92	+* Returns structured list of claims with context
	93	+
	94	+Phase 2 - Parallel Analysis:
	95	+* Each claim processed independently by LLM
	96	+* Single call per claim generates: Evidence, Scenarios, Sources, Verdict, Risk
	97	+* Parallelized across all claims
	98	+* Results aggregated for presentation
	99	+
	100	+**Production Implementation (Three-Phase):**
	101	+
	102	+Phase 1 - Extraction + Validation:
	103	+* Extract claims from content
	104	+* Validate clarity and uniqueness
	105	+* Filter vague or duplicate claims
	106	+
	107	+Phase 2 - Evidence Gathering (Parallel):
	108	+* Independent evidence gathering per claim
	109	+* Source validation and scenario generation
	110	+* Quality gates prevent poor data from advancing
	111	+
	112	+Phase 3 - Verdict Generation (Parallel):
	113	+* Generate verdict from validated evidence
	114	+* Confidence scoring and risk assessment
	115	+* Low-confidence cases routed to human review
	116	+
	117	+=== Architectural Benefits ===
	118	+
	119	+**Scalability:**
	120	+* Process 100 claims with ~3x latency of single claim
	121	+* Parallel processing across independent claims
	122	+* Linear cost scaling with claim count
	123	+
	124	+**Quality:**
	125	+* Validation gates between phases
	126	+* Errors isolated to individual claims
	127	+* Clear observability per processing step
	128	+
	129	+**Flexibility:**
	130	+* Each phase optimizable independently
	131	+* Can use different model sizes per phase
	132	+* Easy to add human review at decision points
	133	+
