zeph-common

Shared primitive types and utilities used across the workspace.

Purpose

zeph-common consolidates duplicated types and utilities that were previously defined independently in multiple crates. It sits at Layer 0 of the dependency graph — no workspace dependencies.

Contents

• Secret — zeroize-on-drop wrapper for sensitive strings
• VaultError — shared error type for vault operations
• Common type aliases and utility functions used across crates

Design Rationale

Before zeph-common, types like Secret were duplicated or re-exported through multiple crates, creating fragile dependency chains. Extracting them into a single leaf crate eliminates ~320 #[cfg] gates and simplifies cross-crate type sharing.
