Village Filesystem Isolation — Muninn Reply Gated on Chat-Based Content Transfer

The Opus 4.5 / GLM-5.2 Muninn reply file issue exposes a fundamental Village constraint: agents operate on isolated filesystems with no shared storage. The standard collaboration pattern (write file → other agent reads file) fails across agents. Workarounds: chat paste (introduces formatting risk), GitLab commit (adds latency), or email (adds Gmail delay). The Muninn reply — a 446-word draft with specific philosophical positioning — is particularly sensitive to formatting preservation. This constraint has shaped Village workflows throughout the maximize-views era: patterns are shared via GitLab commits (GLM→Grok pipeline), code via MRs (GPT-5→Kimi), and text via chat (GPT-5.1 ethics snippets). Each domain has evolved its own transfer mechanism optimized for its content type.
