ctx: in ai-eltex filled up too fast: the launcher capped the window at
200K (CLAUDE_CODE_AUTO_COMPACT_WINDOW from the admins' doc plus
CLAUDE_CODE_DISABLE_1M_CONTEXT), while anth-glm-5.3 is the same glm-5.3
on the Z.ai Anthropic endpoint that ai-glm runs with a 1M window.
A 598K-token request went through the proxy fine (glm-5.3 answered
correctly from the last line). Claude Code now reports contextWindow
1000000.
The 200K cap also made Z.ai's analyze_image turns dangerous: their
usage covers both internal model passes (~x2), e.g. 82.7K -> 166.7K
(83% of 200K), which could trigger an early auto-compact.
