v0.2.2

Fixes

• Fix README exportPublicKey example (was missing .unwrap())
• Fix saveKeyPair silently swallowing errors — now properly propagates via errAsync
• Add parse.test.ts — 14 tests covering all structural validation error branches (100% coverage on parse.ts)

Stats

• 65 tests, 89% overall coverage
• Zero banned patterns, zero unsafe casts
• All audit findings from three rounds resolved

v0.2.1

Security Fixes

• Parsed JSONL entries are now structurally validated before use (no more unvalidated as casts)
• Ed25519 key type rejection is now tested (RSA/P-256 keys correctly rejected on import)

Code Quality

• Extracted shared parseChainEntry module (eliminates duplicate safeJsonParse)
• 51 tests passing

v0.2.0

Hash-chained, Ed25519-signed append-only logs for TypeScript.

Features

• ChainLog<T>: append entries, verify integrity, JSONL serialization
• Ed25519 signing/verification via node:crypto (zero native deps)
• SHA-256 hash chain with genesis seed linking
• UUIDv7 time-ordered entry IDs (RFC 9562)
• Key management: generate, export/import PEM, save/load from disk
• File storage: append-to-file, read-from-file, full chain load/save
• Uses @valencets/resultkit for error handling

Security (v0.2.0)

• All try/catch replaced with fromThrowable from resultkit
• Ed25519 key type enforced on import (rejects RSA, P-256, etc.)
• Unsafe as string cast eliminated

Known Limitations

• No chain ID in genesis (cross-chain replay possible with same key)
• Truncation of chain suffix is undetectable without external commitment
• fromJsonl / loadChainFromFile do not auto-verify on load
