Split the monolithic context.py (117 lines) into five purpose-specific modules following single-responsibility principle: - config.py: Server-level constants (DATA_DIR, SESSIONS_DIR, PORT, STALE_EVENT_AGE, _state_lock) - agents.py: Agent-specific paths and caches (CLAUDE_PROJECTS_DIR, CODEX_SESSIONS_DIR, discovery caches) - auth.py: Authentication token generation/validation for spawn endpoint - spawn_config.py: Spawn feature configuration (PENDING_SPAWNS_DIR, rate limiting, projects watcher thread) - zellij.py: Zellij binary resolution and session management constants This refactoring improves: - Code navigation: Find relevant constants by domain, not alphabetically - Testing: Each module can be tested in isolation - Import clarity: Mixins import only what they need - Future maintenance: Changes to one domain don't risk breaking others All mixins updated to import from new module locations. Tests updated to use new import paths. Includes PROPOSED_CODE_FILE_REORGANIZATION_PLAN.md documenting the rationale and mapping from old to new locations.
