+# Harrier — Insurance Navigation
+
+> *Part of the Circuit Forge LLC "AI for the tasks you hate most" suite.*
+
+**Status:** Backlog — not yet started. Peregrine must prove the model first.
+
+## What it does
+
+Harrier handles the full insurance fight: prior authorization tracking, claim dispute drafting, EOB (Explanation of Benefits) reconciliation, internal and external appeal letters, and state insurance commissioner complaints.
+
+The harrier is low, fast, and persistent — exactly what fighting a denied claim requires.
+
+## Why it's hard
+
+Insurance disputes are engineered to be abandoned:
+- Prior auth processes have no standard timeline or format across insurers
+- EOBs are intentionally opaque — reconciling them against bills requires expertise
+- Appeal deadlines are short (30–60 days internal, 4 months external)
+- The regulatory landscape is complex: state insurance codes, ACA requirements, ERISA for employer plans
+
+## Core pipeline
+
+```
+Log claim / denial / prior auth request
+→ AI analyzes EOB + denial reason → Drafts appeal with clinical rationale
+→ Human review + attach supporting docs → Submit appeal
+→ Track deadline + escalation windows → External appeal / commissioner complaint if needed
+```
+
+## Key differentiators vs. Peregrine
+
+- Medical + insurance jargon parsing (CPT codes, ICD codes, denial reason codes)
+- Regulatory citation engine: state insurance code, ACA provisions, ERISA
+- External appeal automation: state IDRE (Independent Dispute Resolution Entity) filing
+- EOB reconciliation: match line items against Explanation of Benefits

+- Shared `circuitforge-core` scaffold
