Description

The webchat UI status bar displays incorrect context usage metrics, inconsistent with the actual engine values.

Reproduction

1. Open a webchat session
2. Send messages to build up context
3. Compare webchat status bar values vs /status or session_status tool output

Observed Behavior

Webchat status bar shows:

• R927.2k (remaining tokens ~927k)
• Context usage: 1%

Actual engine values (from session_status):

• Context: 41k/200k (20%)
• Actual remaining: ~159k

Expected Behavior

Webchat status bar should match the engine-reported context usage.

Environment

• OpenClaw version: 2026.3.13
• Model: zhipu/glm-5-turbo
• Channel: webchat
• OS: macOS Darwin 23.6.0 (arm64)

Additional Notes

The "R" (remaining) value appears to be calculated from a different/incorrect context window size than what is configured (200k). The 1% figure also does not match the 20% reported by the engine.
