Summary

Upon upgrading to 2026.4.14, the lossless-claw engine appears to be broken. Attempting to communicate with the bot shows this error:

⚠️ Something went wrong while processing your request. Please try again, or use /new to start a fresh session.

Checking the openclaw logs I see the following message:

13:59:11+00:00 error diagnostic {"subsystem":"diagnostic"} lane task error: lane=main durationMs=57 error="Error: Context engine "lossless-claw" factory returned an invalid ContextEngine: info.id must match registered id "lossless-claw"."
13:59:11+00:00 error diagnostic {"subsystem":"diagnostic"} lane task error: lane=session:agent:main:discord:direct:removed durationMs=58 error="Error: Context engine "lossless-claw" factory returned an invalid ContextEngine: info.id must match registered id "lossless-claw"."
13:59:11+00:00 error Embedded agent failed before reply: Context engine "lossless-claw" factory returned an invalid ContextEngine: info.id must match registered id "lossless-claw".

I am using lossless-claw 0.8.2.

Steps to reproduce

1. Update to 2026.4.14.

Impact and severity

Severity is high since it breaks OpenClaw entirely with lossless-claw enabled. lossless-claw must be disabled to restore functionality.
