新版在 1% 流量上质量更好，但延迟超线、安全门失败。你会因为平均分变高就直接推到 100% 吗？At 1% traffic, the new version scores better on quality but misses latency and safety gates. Does a higher average justify jumping to 100%?

02把流量从 1% 推到 100%，逐阶段通过质量、延迟与安全三门Push Traffic from 1% to 100% Through Quality, Latency, and Safety Gates

Canary Release

STAGE

分阶段扩大Staged expansion

流量只在 1%、5%、25%、50%、100% 五个站点推进。Traffic advances through 1%, 5%, 25%, 50%, and 100% stations.

QUALITY

质量门Quality gate

真实流量样本必须维持任务质量。Live samples must preserve task quality.

LATENCY

延迟门尾延迟不能在扩大时越过上限。

Tail latency must stay below its limit as exposure grows.undefined

SAFETY

安全门硬安全门不可用质量收益抵消。

Quality gains cannot offset a hard safety gate.undefined

04最小机制：主交互能逐项验证Minimal Mechanism: Verify Each Link in the Interaction

MECHANISM

promote = quality_pass ∧ latency_pass ∧ safety_pass

每个流量阶段都重算三门；任一门失败，当前推进被拒绝并自动退回上一稳定阶段。All three gates are recalculated at every exposure stage. If any gate fails, promotion is rejected and traffic rolls back to the last stable stage.

请求扩大Request expansion运行三门run three gates

三门全过All gates pass扩大流量expand traffic

任一失败Any gate fails自动回退automatic rollback

05注入安全回退后，仍把流量请求推到 100%Inject a Safety Regression and Still Request 100% Traffic

主动制造失败Create a failure

边界实验Boundary experiment

金丝雀的价值不是显示阶段，而是让失败阶段无法继续扩大，并把流量退回已知稳定点。The value of a canary is not displaying stages. It is preventing a failed stage from expanding and returning traffic to a known stable point.

尚未执行。先在主交互中观察正常机制。Not run yet. Observe the normal mechanism in the main interaction first.

✗ 1% 通过就能直接跳到 100%。Passing 1% permits a jump to 100%.→ ✓ 每个阶段都要重新通过三门。Every stage must pass all three gates again.

✗ 质量更高可以抵消安全门失败。Higher quality offsets a failed safety gate.→ ✓ 安全硬门没有平均或抵消。A hard safety gate has no averaging or offset.

✗ 回退就是把监控图变绿。Rollback means turning the chart green.→ ✓ 真实流量必须回到上一稳定版本。Actual traffic must return to the last stable version.

金丝雀发布按 1% 到 100% 分阶段扩大真实流量；质量、延迟、安全三门缺一不可，失败即自动回退。Canary release expands live traffic from 1% to 100% in stages. Quality, latency, and safety must all pass; any failure triggers automatic rollback.
