Implementation: Define acceptance before code

This series uses AI-assisted voice narration; rely on the page disclosures and text curriculum for the content boundary. Examples are teaching scenarios, not evidence of customer outcomes.
Episode summary
Start with login acceptance criteria and define completion before coding. Work through independently verifiable milestones, use functional, architectural and security checks to detect drift, and base repair or recovery on version evidence.
- Cover success paths, failures and security constraints. Login time limits and lockout counts are examples that require project-specific decisions.
- Review diffs, dependencies and structure for unintended changes to accepted interfaces. File length alone does not establish quality.
- Reassess repeated failures. Shared history, uncommitted work, databases and deployments have distinct recovery boundaries; one Git operation cannot restore an entire system.
This is an editorial learning summary, not a transcript. Check the text lessons for conceptual boundaries.
Practice after watching
Define acceptance criteria for valid, empty and unauthorized requests to a synthetic ticket endpoint. Record a version checkpoint and the preservation and diagnosis steps for a failed repair.
