How the chain works
1
Every action is recorded: tool, node, args, result, status, timestamp.
2
Each entry is hashed: SHA-256(ts|tool|node|args|result|status|prev_hash). The previous hash is always chained in.
3
Chain starts at GENESIS. Any modification to any past entry invalidates all subsequent hashes — O(n) tamper detection.
