Requirement is still ambiguous
Keep the change in discovery; do not encode a guessed rule.
In practice · Continuing improvement
A business request becomes a tested release and a changed operating guide.
The service is not “AI changes production.” It is a controlled path from an approved Northline requirement to engineering evidence, release identity and updated instructions.
Story 03 · intended outcome
The requested rule changes without losing accountability.
Northline asks for a minimum-order rule to match its commercial policy. The request is fictional and used to explain the delivery method. Its future release identity is a placeholder—not evidence that this exact change has been built or deployed.
- Request
- Northline minimum-order rule: identify thresholds, examples, affected channels and expected result.
- Acceptance examples
- Orders below, at and above the boundary behave as approved; payment state remains distinct.
- Evidence package
- Scoped source diff, automated test, review result and release note.
- Operator impact
- The applicable guide changes in the same release batch.
The delivery path
A repeatable change cadence with explicit owners.
Frame the business result
The client explains the rule, real edge cases and priority. The delivery team turns those into examples and identifies configuration, integration and code boundaries.
Choose the smallest correct mechanism
Use configuration for an existing supported setting; integration for an external boundary; bespoke code only where the business distinction truly requires it.
Implement against one contract
Change the owning source rather than hiding a mismatch with page-specific coercion or duplicate data shapes.
Validate the important cases
Run focused automated checks, then review the changed workflow in an appropriate nonproduction environment. A passing build alone is not user acceptance.
Release by identity
Promote the validated artifact/configuration with a recorded version and rollback path. The website does not claim a release exists until that evidence is bound.
Update the operating record
Revise the guide, applicability and proof references so operators understand the new behavior and unchanged boundaries.

Change without theater
What prevents “continual improvement” from becoming vague.
Configuration already fits
Prefer the supported setting and document it rather than commissioning unnecessary bespoke code.
Test passes but workflow fails
The release remains unaccepted. Correct the implementation or the source-backed instruction.
Guide and release disagree
Treat documentation as part of the batch; do not publish stale operating steps as verified.
