Complete architecture pivot: remove tmux dependency and the internal cc-sup Rust supervisor, replacing both with heimdall (hm) — the standalone, tested, released PTY session supervisor. Session management: - Replace tmux pane polling with heimdall Unix socket protocol - Add supervisor_client.py: async client for heimdall binary framing - Web terminal via WebSocket relay to heimdall subscriptions - Agent state machine from heimdall classifier (idle/thinking/ streaming/tool_use/dead) - Session creation launches `hm run --detach` instead of tmux - Agent pruning probes heimdall status sockets every 5s Architecture changes: - Delete cc-sup/ directory (1,474 lines of Rust replaced by heimdall v1.0.0 with 5,480 lines, 92% coverage, 254 tests) - Remove dashboard plugin system (BaseDashboard, discovery.py) — replaced with direct HTMX partials - Remove APScheduler — replaced with asyncio background tasks - SSE event bus for real-time dashboard updates - Agent identity via DRASILL_SESSION_ID env var (set by heimdall pre-exec seam) New features: - /health/deps dashboard page: dependency health checks with green/red status, versions, install links - Shared doctor.py module for CLI (check-deps) and dashboard - claude added as required dependency check - hm clean-logs recipe in justfile for orphaned log cleanup Plugin hooks: - Stop hook checks inbox via DRASILL_SESSION_ID - Idle notification hook injects messages at idle prompt - No join/leave commands — platform owns agent lifecycle Docs updated: ARCH.md, mesh.md, terminal.md, plugin.md, database.md, deployment.md, SKILL.md, README.md, CLAUDE.md
