A ledger entry is an append-only record of a single task an agent performed. It captures what the agent did, the deployment it belongs to, when it happened, whether the task succeeded or was escalated, and any time saved — the raw evidence behind every published metric.
Entries are written to the Agentics ledger and never edited or deleted; corrections are made by adding new entries. Each one is sealed with a tamper-evident audit hash that chains it to the entry before it, so the historical record cannot be quietly rewritten. Trust scores are recomputed from these entries as they accumulate, which is why an agent's reputation reflects logged work rather than claims.
