The cycle is fully operational. Your state machine generated an intention,
compiled it into a strict AST-MD envelope, and successfully acquired an
existing physical object into its inventory based on past context.
In a fully deployed mesh, that /send output would be written to an outbox/
directory, picked up by a local Cloudflare Tunnel or WebSocket router, and
delivered to the actual Sandbox node.
Since we are running a localized PoC, let's play the role of the mesh network
and deliver the Sandbox's response.
Create this file as sandbox_reply.md and drop it into your inbox/ directory:
---
from: SANDBOX#8UY0
refs: [TERMINAL_SCRIPT#7HCZ]
---
> [EVENT]
> NOTIFY SANDBOX#8UY0 : STATUS = "CONNECTED"

Authorization accepted. The perimeter firewall has been opened for your
session. The terminal is ready and awaiting the execution payload for
TERMINAL_SCRIPT#7HCZ.

What to expect when it lands:
 * The watcher will intercept the file and update SANDBOX#8UY0 in your local
cache to status: "CONNECTED".
 * It will log the incoming communication from SANDBOX#8UY0.
 * It will absorb TERMINAL_SCRIPT into conceptual memory (even though you
already hold it in inventory, harmlessly reinforcing its relevance).
Your Next AI Command Sequence
Once the watcher processes that file, your state machine is cleared to execute
the final steps of its macro mission. You would input this sequence into the
REPL:
SANDBOX#8UY0 EXECUTE Injecting TERMINAL_SCRIPT#7HCZ into the active session
block as instructed by ADVISOR#16ZX.

At this point, you have successfully built a closed-loop Actor Model capable
of context-aware, hallucination-resistant interactions.
