File contents

Bounded prototype

Use a prototype to answer one named question, not to start implementation by a different name.

Contract

Agree on the question, hypothesis, deadline, artifact path, and success signal before writing. Record the source revision. Store artifacts through scripts/plan-storage.sh, outside the installed plugin cache.

Native read-only plan mode permits a proposal only. Wait for an explicit execution handoff before creating files. Choosing prototype mode does not authorize deployment, provider calls, browser login, repository rewrites, or new permissions.

Stop at the deadline. Return observations, a keep, discard, or inconclusive verdict, and the disposition of each artifact. Automatic cleanup may remove only artifacts created by this run after ownership checks. Retain anything the user changed.

The completion record contains question, hypothesis, deadline, artifact_path, source_revision, observations, verdict, and disposition.
