5.0 Review
Learn what shipped, then remove what no longer belongs.
Runtime usage, activity history, cleanup review dates, and stale-flag signals turn feature flags from launch scaffolding into managed release history.
Practice
The last release step is removing the flag while the context is fresh.
Runtime usage
See whether a flag has served traffic and which environments have been exercised before calling a release complete.
Activity history
Review flag edits, targeting replacements, key changes, and kill-switch actions in a readable sequence.
Cleanup review
Temporary flags surface when they are due, globally shipped, unused, or behaving like stale rollout work.
Product proof
A release leaves signals.
FeatureGate records aggregate runtime usage and organisation activity without storing raw evaluation context, user identifiers, raw flag values, or targeting attributes in the request path.
- Aggregate usage, not raw context
- Readable activity history
- Cleanup review for temporary flags
- Archive after guarded code is removed
What changes
The habit behind the feature.
Use production signal before cleanup
A flag that is off everywhere is not automatically stale on day one. Review signals become useful once the flag has real runtime context.
Archive after code cleanup
The healthy path is a small cleanup branch that removes the guarded code path, followed by archiving the flag so future readers do not inherit dead decisions.
Keep analytics deliberately narrow
Aggregate counts and activity are enough for release hygiene. Raw evaluation context and user identifiers stay out of telemetry.
