回到汉堡王的案例上,一个好的门店经理,本来就应该知道员工的服务状态。通过巡店、带教、日常反馈来调整,通过观察一个员工在午餐高峰期的眼神和节奏来判断状态,通过在下班后聊两句来了解谁最近压力大。但这需要经验,需要在场,需要判断力——而这些恰恰是连锁快餐业最稀缺的东西。

Where we diverged: WebVideoCreator was built against the old headless mode on the main chrome binary. Since then, Chrome split the old headless mode into a separate chrome-headless-shell binary with a different API surface (starting with Chrome 120, fully removed from the main binary in Chrome 132). We also needed tighter integration with our cloud infrastructure (Cloud Run, GCS uploads, Datadog tracing), stricter security (SSRF protection for rendering untrusted URLs), and more control over the video element pipeline and audio extraction. So we rewrote it in TypeScript with modern Puppeteer and adapted the architecture for our deployment model.
The code runs as a standard Linux process. Seccomp acts as a strict allowlist filter, reducing the set of permitted system calls. However, any allowed syscall still executes directly against the shared host kernel. Once a syscall is permitted, the kernel code processing that request is the exact same code used by the host and every other container. The failure mode here is that a vulnerability in an allowed syscall lets the code compromise the host kernel, bypassing the namespace boundaries.
