Verify — offline, no server verdict

engrave verify never asks the server whether a proof is valid — it recomputes the whole chain locally. Point it at an exported evidence pack and it needs no network at all:

engrave verify --offline-pack ./evidence.json

| Command | What it does | |---|---| | record <key> | Append an entry (--data, --type, --durability) | | get <key> | Read the latest value (--verify to check it offline) | | tx <id> · history <key> · search | Browse the ledger | | verify [ref] | Verify an entry or an offline pack — no server trust | | watch | Tail the ledger, continuously verifying consistency | | export | Download a self-contained evidence pack | | mcp proxy --upstream … | Wrap any MCP server so every agent tool call is engraved | | run start / span / run end | Record an agent run as hash-linked spans | | keys list / create / revoke | Manage API keys |

Add --json to any command for the stable {ok, data} machine envelope.
