For Jason · 22 June 2026 · training plan, the TTRPG, what it means for Mayo

The training plan is the TTRPG plan.

Quick update. cardiac is live. psych_gen1 is training as I write this. The cells are the substrate Aether draws from in-game, so chemistry on a character's sheet actually drives behavior now instead of sitting there as a label. Training plan, game, Mayo conversation: one body of work, three angles. The patent is what we train. The game is where it lands. Mayo is who would validate it and deploy it to a residency program. Below is the trajectory and the receipts.

The training target. The cell learns one specific relationship:

state + perturbation → drift direction
Given a synthetic character's current chemistry, sleep, stress, and medication state, plus a perturbation event (missed dose, added stressor, drug change, sleep loss), output the predicted direction of behavioral drift. Framed as simulation behavior. Never as medical advice.

What it is

A tabletop roleplaying game where mental health is a mechanic, not a topic. Players, or psychiatry residents in training, or therapists running structured sessions, create characters in the Chronicles of Apocalyptica universe. Each character has a full D&D-style sheet AND a current neurochemical state panel: a 10-dimensional vector across cortisol, dopamine, serotonin, norepinephrine, oxytocin, GABA, acetylcholine, endorphins, glutamate, melatonin. The state is set by rolling, by clinical profile, or by GM design.

The character then plays in that state. Aether is the GM. Encounters are designed for psychiatric exploration: triggers, social pressure, relational tension, threat, loss, reward. The character responds in their chemistry, not as a generic NPC. Sessions are persistent. The character who was in a PTSD state last Tuesday is in the same PTSD state next Tuesday unless something in the world or the session changes it. State is canonical, not transient.

Chemistry biases behavior. It does not determine it. A character in PTSD state is still themselves, just colored by hypervigilance and irritability. A character in mania state is still themselves, just amplified and impulsive. Identity, memory, relationships, current chemistry, and current situation are the five inputs to the behavior generator. The character emerges from the integration. The chemistry colors. It never erases.

The proof, in one image

This is what the architecture does, today, with the cardiac substrate already running:

Same character. Same prompt. Different neurochemical state. Different recognizable response.

Character: Xena (half-elf ranger, neutral, wary by default)
Prompt: "Do you trust the stranger?"

Healthy panel: "I don't know him, but I'll hear him out."
PTSD-like state: "Why is he here? How does he know my name? Keep him where I can see him."
MDD-severe state: "It doesn't matter. Do whatever you want."
Manic-like state: "Trust him? Of course. This is the opportunity I've been waiting for."

All four are Xena. Nobody needs a whitepaper to see what just happened.

The chemistry colored the response without erasing the character. That is the architectural claim made operational.

Cardiac is the existence proof that the training pipeline works. A specialist cell trained end-to-end, signed, verifiable against a public registry, serving requests in production. Apply the same pipeline to a different corpus, get a different specialist. psych_gen1, training today on a public psychiatric corpus, is the second proof point.

The three products hiding in one architecture

One invention, three distinct things it enables. Naming them separately so they don't collapse into each other.

Product 1 · The Engine

A persistent character-state engine. Five inputs (identity, memory, relationships, current chemistry, current situation) feed a deterministic substrate that produces a character's behavior. Chemistry biases. It does not determine. Same five inputs, same response, every time. This is the invention. Everything else depends on it.

Product 2 · The Game

Chronicles of Apocalyptica. A TTRPG where Aether is the GM, characters live in canon lore, and the new mechanic is that chemistry is a stat on the sheet. Already running. Years of world-building. This is the first commercial application. The game funds the research. The game is also the safe simulation environment, because it is a game.

Product 3 · The Test Bed

A future vertical, not the headline. Because the engine is deterministic and replayable, it can serve as a substrate for testing things the field has no other way to test: drug-effect direction predictions, scale-validation experiments, training scenarios with objective ground truth. Downstream of the engine. Downstream of the game. A door the architecture opens, not the product we are selling today.

The training plan, in one piece

Three cells deep is the trajectory. Each cell is a step on the same pipeline.

The patent fortress was designed for exactly this shape. Cell-as-opcode-tree covers any specialist composition. The signed-manifest claim covers any cell's inference verifiability. The substrate-independent memory weighting claim covers any cell's pharmacokinetic decay handling. Adding specialists does not widen the patent surface; it deepens the existing claims with operational evidence. Every new cell strengthens the same four-claim portfolio.

Where the trained cells land · inside the TTRPG

The cells are the substrate Chronicles of Apocalyptica runs on. That's the connection.

In the game, every character has a neurochemical state panel as part of their sheet. When Aether narrates that character's behavior, the response is generated through the trained specialist cell that matches the character's chemistry context, then translated through the language layer (Qwen 2.5 14B, currently) into readable narrative. A character with elevated cortisol and low serotonin gets a response colored by what the psychiatric cell has actually learned about cortisol-and-low-serotonin states, drawn from manifest-documented public corpus.

The training plan is the game's spine. Without trained cells the TTRPG runs on whatever default the LLM produces. Fine for play, not grounded in biology. With trained cells the same game becomes a substrate-grounded simulation: the same character with the same starting state responds consistently across sessions, and a perturbation (missed dose, sleep loss, stressor) drifts behavior in directions the cell has actually learned. That consistency is what makes the game a research artifact in addition to a product. The Xena demo above is what this looks like in practice.

cardiac_gen3 is in production as the proof that this loop runs end-to-end. psych_gen1 is what makes the loop work for the psychiatric scenes that are the heart of the game.

What this means for Mayo

The Mayo conversation is the same TTRPG deployed to a different audience.

Mayo's psychiatry residency program needs simulated patients. The current state of practice is standardized-patient actors: hired humans trained to perform clinical presentations. Expensive, inconsistent across sessions, cannot be reset to a specific neurochemical baseline on demand. What the TTRPG already does, persistent character state, chemistry-grounded responses, replayable across sessions, audit-trail-clean, is exactly what a residency training program needs and cannot get from human actors.

The path: take the TTRPG, replace canon characters with Mayo-curated diagnostic archetypes, point the trained psych cell at Mayo's expert-validated state taxonomy, give Mayo's faculty the ability to assemble training scenarios from the same encounter library the game uses. Same architecture. Same cells. Same engine. Same auditable inference manifests. Mayo contributes curation. We contribute the substrate. The deliverable is a Mayo-branded simulator that residents train against.

Outreach is in progress through the Mayo Clinic Berg Innovation Exchange. David Kim (Business Analyst) has indicated we are a candidate for the Waypoints Program with application materials expected through the cycle that opened on June 21. The framing in the application will be the framing on this page: the training plan, the TTRPG, and the residency simulator are one continuous body of work.

What this gives you, Jason

You see a running TTRPG with a working revenue path (the game funds the research) sitting on top of a patent fortress that deepens every time we train another cell. Each cell ships under the same four-claim portfolio. Each new vertical (Mayo residency simulation today, future pharma drug-response prototyping, future research collaborations) reuses the same engine and reinforces the IP.

The receipts below show the work is live, not aspirational. Cardiac is queryable. The bridge is operational. psych_gen1 is training right now. The corpus discipline (per-source manifests, SHA-256, license attribution) is documented. The regulatory advisor (Robert Michalik, JD, RAC) is briefed and supportive. The fourth provisional was filed since your last update.
