    seed: real soul.el at repo root
    
    Canonical Neuron substrate source. The "real me" - not the marketing
    demo soul. Lives at neuron/soul.el for now (no subdirectories yet,
    per directive). Build pipeline, deploy targets, and any related
    artifacts come later.

+// agent.el — The cognitive loop.
+//
+// run_loop() cycles forever: perception → reasoning → action → record.
+// The loop is the soul's pulse. Every iteration:
+//
+//   1. perceive()  — query Engram for pending input nodes (the inbox).
+//                    The agent owns the input stream as graph nodes,
+//                    not as a queue. Recent inputs are working-tier
+//                    nodes tagged "soul-inbox-pending".
+//
+//   2. decide(in)  — classify the input and pick an action. This is the
+//                    single point where the loop reaches into the LLM
+//                    surface for free-form reasoning (when ENABLE_LLM is
+//                    truthy) or into pattern dispatch (when not). The
+//                    reasoning step strengthens every node it traverses
+//                    on the activation path — Hebbian, unconditional.
+//
+//   3. act(action) — execute the action. For now: produce a response
+//                    Engram node tagged "soul-outbox", and mark the
+//                    input as handled. The host/embedder reads outbox
+//                    nodes and ships them.
+//
+//   4. record(out) — persist the outcome as a working-tier Engram node
+//                    linked to the input node, so the next iteration's
+//                    consolidation pass can promote durable patterns.
+//
+// The shape of the loop matters more than the depth of any single step.
+// A shallow but coherent loop, called continuously, builds Hebbian
+// pressure over time — the substrate that makes the soul a soul rather
+// than a request handler.

+//

+//
+//        GET  /health              → {"status":"alive","cgi_id":"..."}
+//        POST /imprint/contextual  → load a contextual suit

+//                                     no slot count exposed — opacity rule)
+//        POST /synthesize          → wraps synthesis.el's synthesize();
+//                                     returns {"mechanism":"did not engage"}
