Feature Flagging
Checks for feature flag services, environment-based toggles, and progressive delivery patterns.
Feature flags decouple deployment from release, enabling canary launches, A/B tests, and instant kill-switches for bad features.
Velocity Governance · Sentinel-10 Protocol
Protocol 5.8 is one of the 10 engineering practices Concordance flags as most degraded under AI-accelerated development. That 3 publicly-documented incidents in this Index already failed it — before AI was the dominant velocity driver — is exactly the pattern the Velocity Governance thesis predicts will accelerate.

Incidents that failed this protocol
CrowdStrikeJul 2024civilizational
Falcon sensor channel-file update crashes 8.5M Windows hosts
No feature flagging / staged rollout for content updates — global simultaneous deployment.
Knight Capital GroupAug 2012civilizational
Knight Capital loses $440M in 45 minutes from incomplete software deployment
Feature flagging: a dormant test function was activated by a repurposed flag — clean feature-flag lifecycle would have removed dead code paths.
FastlyJun 2021civilizational
Single customer config change triggers global Fastly CDN outage
Feature flagging: software was deployed to 100% of POPs with no feature flag that could have isolated the bug to a subset.
