Mechanisms¶
- Canary Region Probe
- The discipline is to place canaries by risk, keep their stimuli representative, and check which regions lack a canary against a coverage view rather than assuming full coverage.
This sourceRecommends risk-aware canary populations and representative traffic rather than assuming a canary covers every operating condition.

- Canary Release
- Consumed against an explicit error budget,
This sourceCanary releases measure a new version's production impact while limiting the fraction of the error budget exposed to defects.
- Consumed against an explicit error budget,
- Feature Flag
- Fine targeting contains blast radius
This sourceExplains that limiting a canary release to a small portion of production traffic reduces the impact of defects while they are evaluated.
- Fine targeting contains blast radius
- Sandbox or Pilot Pathway
- They wrap the new model in a canary release:
This sourceDefines a canary as a partial, time-limited production deployment and describes feature flags that allow a feature to be selectively disabled by changing configuration.
- They wrap the new model in a canary release:
Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 4 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
