Memory

The cache answers whether Once can reuse a result. Memory records evidence about work that already ran, so a person or tool can inspect its status and provenance without scraping terminal output.

Once currently records action evidence after:

• once exec
• once run
• once build
• once test

Each record identifies its subject, pass or fail status, action digest, cache state, exit code, captured stream digests, and declared output digests when they exist. Records belong to the current project and remain queryable across command invocations.

Evidence does not decide whether a result can be reused. That remains the action cache's job. Instead, it provides an inspectable account of which action ran and whether the result was computed or restored.

The Evidence guide continues the scripted workflow from earlier pages. It runs the same action twice, changes an input, and compares the resulting records.
