- What it covers
- A single, complete log entry per decision: what went in, what the system retrieved, which tools ran, and what came out.
- How to build it
- One structured log record per decision, keyed to the release version above. Capture all four elements. Do not log only the final output.
- Produces
- A decision that you can read back in full. You do not rebuild it from whichever pieces happened to be logged.
- Tradeoff
- Logging full inputs and retrieved context at this detail costs storage. For personal data, it also forces a privacy-scoping decision. It is not free.
- Prove it
- A decision picked at random resolves to a complete log entry. Someone checks this. A written policy does not count.
