Provenance Ledger
Log every agent decision and state change to an immutable append-only ledger with full metadata — so any past action can be explained, audited, or reversed on demand.
Intent & Description
🎯 Intent
Log every agent decision and state change with enough metadata to explain or reverse it later.
📋 Context
An agent that approves insurance claims, modifies production records, or sends money will eventually face a regulator, customer, or internal auditor asking why it did what it did on a specific date. Answering requires the action, the reasoning chain, retrieved evidence, and model version that surrounded it — weeks or months after the fact.
💡 Solution
Append events to an immutable log with: timestamp, actor, action, target, justification (link to thought or decision), diff hash. Enable rollback by event id. Reject events that lack required fields.
Real-world Use Case
- Agent decisions and state changes must be explainable or reversible after the fact.
- An immutable, append-only log can be operated and queried.
- Each event can carry timestamp, actor, action, target, and justification fields.
Source
📌 TL;DR
Every consequential agent action gets appended to an immutable ledger with full metadata — so “why did the agent do that three weeks ago?” is always answerable.
Advantages
- Audit and rollback become tractable — not forensic guesswork.
- Failure patterns become visible across time — you can see clusters of bad decisions.
Disadvantages
- Log volume can dominate storage at scale — requires retention and archiving policies.
- Justification fields require the agent to populate them; lazy or prompt-shortchanged agents skip them.
