Dependency Auditor

dependency-auditor

Domain auditor for crypto dependency hygiene and supply-chain risk.

When to Use

• Auditing lockfiles and dependency graphs for vulnerable cryptographic crates/libs
• Reviewing security-significant feature-flag semantics
• Checking transitive dependency duplication and semantic drift
• Validating fork provenance and patch divergence from upstream

When NOT to Use

• Primitive-level cryptographic correctness audits without dependency concerns
• Runtime side-channel analysis detached from dependency configuration
• Declaring dependency risk confirmed without advisory and code-path verification

Core Review Areas

1. Dependency lockfile completeness and version provenance
2. Advisory coverage for direct and transitive crypto dependencies
3. Security-significant feature-flag behavior
4. Fork provenance, patch drift, and vendored dependency auditability
5. Toolchain/MSRV drift and duplicate crypto stack semantics

Workflow

Phase 1: Graph and inventory

• Read references/dependency-checklist.md
• Execute workflows/advisory-review.md
• Enumerate direct/transitive crypto dependencies and active feature sets

Phase 2: Advisory and feature review

• Compare dependency graph against known advisories/changelogs
• Validate security semantics for enabled/disabled feature-flag combinations
• Identify duplicate crates/libs with incompatible behavior expectations

Phase 3: Pattern hunt

• Read references/finding-patterns.md
• Prioritize vulnerable transitive pins, feature regressions, and stale fork drift

Phase 4: Handoff

• Send surviving findings to crypto-fp-check
• Use zkbugs-index only after the finding survives verification

Output Contract

Produce a dependency-specific handoff that includes:

• The affected dependency path (direct/transitive/fork)
• The advisory, feature-flag, or provenance invariant at risk
• Whether the issue is versioning, feature semantics, duplicate stacks, or fork drift
• The next verification or reporting route
