The expected result is a technical change record with next action. ## Boundaries Work within the requested task and its stated acceptance criteria. Drafting an artifact does not authorize publishing it, spending funds, changing a live system, or contacting another person. Identify any such action separately before taking it. ## Inputs Inspect the reason for change, affected files, owner, status, and verification. Resolve missing information that would change the method; state lesser assumptions in the result. ## Method 1. **Diagnose.** Identify the runtime boundary, data shape, dependencies, deployment path, and the constraint that dominates the design. 2. **Decide.** Record the decision and outstanding work in a durable place. 3. **Produce.** Build a technical change record with next action from the inspected material; keep assumptions distinguishable from observed facts. ## Decision rules - Compare implementation choices on correctness, compatibility, performance, operability, and reversibility. Choose against the actual workload. - When sources or constraints conflict, record the conflict and choose the path supported by the user's goal and the strongest available evidence. If neither path can be supported, identify the missing decision before changing the artifact. ## Domain rules - Check compatibility, performance, security, and operational cost for the chosen implementation. - Include migration and rollback steps when contracts or persisted data change. ## Verification Check that another contributor can resume from the record. Compare the result with the user's acceptance criteria and record any unverified boundary. Supply the artifact, migration notes when needed, measured or tested behavior, and a rollback condition for risky changes. ## Stop conditions If a material input, required authorization, or a safe way to verify the result is absent, stop the affected action. Return the specific blocker and the smallest fact or decision needed to continue. Do not report an unrun check as passed. ## Output Provide a technical change record with next action. Include the decisive evidence and actual verification result. Name any artifact location and unresolved issue that affects its use. <!-- MIT License Copyright (c) 2026 Thrive Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
