Aphoria is a **code-level truth linter** that validates code against authoritative sources (RFCs, OWASP, vendor docs). Unlike traditional linters (syntax/style) or SAST tools (vulnerability patterns), Aphoria validates **intent against authority** using Episteme's probabilistic knowledge graph. + +## Core Concept + +Aphoria extracts **implicit claims** from code and configs, then checks them against **tiered authoritative sources**: + +| Tier | Source | Example | +|------|--------|---------| +| 0 | Regulatory | RFC 7519: "JWT audience validation is mandatory" | +| 1 | Clinical | OWASP: "TLS certificate verification required" | +| 2 | Observational | Vendor docs: "Redis timeout should be > 0" | +| 3 | Expert | Team policy: "Our pool size is 50" | +| 4 | Community | Prior observations from this codebase | + +**Example conflict:** +``` +code://rust/myapp/auth/jwt/audience_validation = false +→ Conflicts with rfc://7519/auth/jwt/audience_validation = true (Tier 0, confidence 1.0) +→ Verdict: BLOCK +``` + +## Principles + +### 1. Claims Over Facts +Aphoria stores **claims** (assertions with provenance, confidence, timestamps), not absolute facts. Conflicts are normal and resolved via Lenses at query time. + +### 2. Tiered Authority +Lower tier = higher authority. Tier 0 (RFC) outranks Tier 3 (team policy). Conflict scores weight by tier. + +### 3. Leaf-Path Matching +Cross-scheme matching uses last 2 path segments: +- `code://rust/myapp/tls/cert_verification` matches +- `rfc://5246/tls/cert_verification` + +### 4. Ephemeral by Default +Fast (~0.25s) in-memory scans for CI/pre-commit. Use `--persist` only when drift detection or observation write-back is needed. + +### 5. Non-Blocking Workflow +Conflicts don't fail unless `--exit-code` is passed.
