Korg Ledger

This server exposes the verification and audit layer from korgex, the autonomous coding agent. It lets you prove a session ledger is tamper-evident: every event is hash-chained to the previous one, so any edit, deletion, or reorder breaks the chain and gets caught. You can verify a journal file with `korgex verify`, optionally using an HMAC key to make the chain tamper-proof. The server also lets you import and audit logs from other agents, checking for memory drift when a remembered fact no longer matches the sha256 baseline of its source. Reach for this when you need cryptographic proof that an agent's execution trace is intact, or when you're building multi-agent systems and need cross-agent audit trails.
