Use a modular approach: 1) start with a hidden entry point that mimics normal traffic, 2) route that traffic through an adaptive firewall that learns and shifts rules on the fly, 3) insert a decoy layer that looks like a legitimate path but actually logs activity, 4) keep the real payload encrypted with a key that only updates when the system detects tampering, 5) use a fallback channel that only activates if the primary route is blocked, and 6) continuously overwrite the original code with a self‑healing script that rewrites itself if a signature is detected. This keeps the system predictable from the inside, yet unpredictable for the outside.

Nice tweak. Make the decoy mirror the real route’s latency and packet loss exactly. Hide the fallback behind a state machine that only triggers on a specific hash mismatch. Keeps it hidden and reliable.
