-## Console Anti-Drift
-
-The interactive console **MUST** remain:
-
-- PTY-backed
-- Agent-owned
-- WebSocket-based
-- Full duplex (input + output)
-
-Disallowed:
-- Log tailing as "console"
-- Exec-per-command models
-- Frontend-owned processes
-- Proxmox console passthrough
-
----
-
-## Upload Anti-Drift
-
-The upload pipeline **MUST** remain:
-
-- Streamed via raw `http.request` piping in the API
-- Direct runtime write in the agent (no staging, no symlinks)
-- Enforced by agent allowlist only (portal does not enforce security)
-
-Disallowed:
-- `fetch()` for upload proxy
-- Staging folders
-- Symlink-based deployment
-- API re-implementing agent filesystem policy
-
----
-
-## Auth Anti-Drift
-
-All auth must flow: `Portal → JWT → API`
-
-Disallowed:
-- CSRF token logic
-- Cookie-based authentication
-- APIv1 patterns
-- Pterodactyl auth patterns

-## Drift Response
-
-If drift is detected:
-1. Revert the change
-2. Document why it was tempting
-3. Re-apply only what serves usability and real architecture
