# Canary and Traffic Shift
|
|
|
|
M12 canaries are bounded evidence producers, not automatic promotion mechanisms. A successful run
|
|
ends in `READY_FOR_PROMOTION_REVIEW`; an operator must explicitly commit the plan.
|
|
|
|
Request-level canary is valid only for compatible stateless capability contracts and can be scoped
|
|
to explicit clients/projects, request count and traffic percentage. Gates include error rate, p95,
|
|
capability health, scheduler capacity, critical project failures, external pressure and worker
|
|
health. Health, error, latency, critical regression or capacity failure triggers automatic rollback.
|
|
|
|
Embedding spaces are never percentage-mixed inside an index. A `requires_reindex` plan accepts only
|
|
`SHADOW`, `DUAL_READ` or `EVALUATION_ROUTE` semantics against a separate index/space. The current
|
|
ExampleRAG alias is outside all M12 rehearsal targets. ExampleVision Vision cannot start a production
|
|
canary while owner-photo production validation is deferred; only an isolated LAB rehearsal is valid.
