OpenClaw: LINE webhook handler lacks shared pre-auth concurrency budget before signature verification

Summary

LINE webhook handler lacks shared pre-auth concurrency budget before signature verification

Current Maintainer Triage

• Status: open
• Normalized severity: low
• Assessment: Shipped v2026.3.28 lacks a shared pre-auth concurrency budget on the public LINE webhook path, but the effect is bounded transient availability loss only, so low fits.
