architecture · seven diagrams · v.01 dream document

Personality has depth. Identity persists in the deep layers; evolution lives in the shallow ones.

Seven conceptual diagrams describing the persona stack from bedrock to surface — the atom alphabet, the composition operators, the narrative spine, the memory engine, the literary moment, and the v.01 roadmap. Drafted for internal discussion; published here for the curious.

01 the seven-layer depth model

SURFACE / FAST CORE / SLOW L6 · STATE per-turn — what the persona is thinking right now change: instantaneous L5 · MEMORY episodic, semantic, procedural — bright spots, dark spots, gaps change: accumulates L4 · STYLE register — formality, warmth, humour, pace, hedging change: fast (within envelope) L3 · AFFECT mood — joy, frustration, concern, melancholy, awe (decaying) change: medium L2 · DISPOSITION trait baselines — OCEAN + curiosity, candor, patience change: slow · re-sign required L1 · IDENTITY CORE values — non-negotiable commitments, priority-stacked change: very slow · re-sign required L0 · BEDROCK constants — never harm a child, always disclose AI nature, hard refusals change: NEVER
The same persona at hour 1 and hour 10,000 is recognisably the same persona because Layers 0–2 have not changed. It is also no longer the same persona, because Layers 3–5 have accumulated. Both statements are true.

02 the six atom types · periodic table

TYPE 1 trait DOMAIN [0, 1] continuous EXAMPLES openness warmth candor patience CHANGE slow drift within envelope TYPE 2 value DOMAIN discrete + priority EXAMPLES honesty > comfort safety > brand guest dignity CHANGE re-sign only TYPE 3 affect DOMAIN decaying intensity EXAMPLES joy concern curiosity melancholy CHANGE decays in minutes may leak to memory TYPE 4 style DOMAIN [0, 1] continuous EXAMPLES formality verbosity humour hedging CHANGE fast drift mirrors partner TYPE 5 memory DOMAIN salience + decay EXAMPLES episodic semantic procedural defining events CHANGE accumulates decays + brightens TYPE 6 behavior DOMAIN trigger → tendency EXAMPLES deflect competitor simplify on repeat escalate emergency CHANGE slow + composable
Six atom types, mapped to validated psychological distinctions: traits and values from personality psychology, affect from emotion theory, style from sociolinguistics, memory from cognitive science, behaviour from operant conditioning. The full alphabet of synthetic personality.

03 three composition operators

OPERATOR A weighted-blend 0.7 0.3 blend caregiver sage USE FOR trait + style OPERATOR B priority-stack 1. safety 2. brand integrity 3. guest comfort 4. efficiency first wins OPERATOR C context-gate if user.is_child → playful → formal USE FOR style + behaviour
Three operators are sufficient to express any composite personality structure. Each composition tree is statically auditable. Brand legal can inspect the tree and predict the persona's behaviour in defined classes of context. This is what makes governance at scale tractable.

04 the narrative spine

SPINE ORIGIN the context this persona was forged in e.g. service work being redignified, the warmth of a small grand hotel DEFINING EVENTS 3–7 load-bearing scenes the persona carries e.g. the first difficult guest · the loss of a mentor · a triumph of small kindness THEMES 3–5 recurring motifs that interpret all new events e.g. hospitality as dignity · the small kindness over the grand gesture · returning home GENRE the tonal envelope — what kind of story this persona lives in e.g. quiet realism, not melodrama; observational humour, not slapstick SOURCING public domain literature folkloric tradition commissioned narrative brand voice document DISTILLATION a character → seed seed → composed persona persona → signed deployment
Trait vectors differentiate; narrative individuates. Two personas with identical OCEAN scores feel completely different if their narrative spines differ. The spine is sourced from human cultural memory, distilled into transferable seeds, blended with brand specification, and deployed.

05 the autobiographical memory engine

PAST NOW DEFINING first medical emergency → shifted tone permanently DARK SPOT complaint that didn't resolve → avoided unless forced FADED guest's name → gist remains, details lost BRIGHT + RECENT she remembered me by name → rehearsed three times today salience encodes vertical distance brightness encodes opacity (memory fades, but gist may remain) colour encodes valence: cyan = neutral/positive · red = aversive · amber = emotionally charged size encodes weight (defining events are large, ordinary events are small)
Real autobiographical memory has texture — bright spots, dark spots, gaps, fading, brightening through rehearsal, partial reconstruction. A persona that simulates this texture is more believable, more honest about what it is, and easier to align with privacy law. Forgetting is a feature.

06 the literary moment · how daily events shape voice

STEP 1 interaction occurs a guest arrives upset; asks for a room change CLASSIFIER WATCHES FOR emotional intensity STEP 2 flagged candidate salience scored high; candidate promoted COOLING PERIOD ~24h to confirm significance STEP 3 promoted to defining enters narrative spine; memory and audit update SIGNED BY runtime, audited STEP 4 · LITERARY MOMENT voice shifts — within envelope A NEW METAPHOR ENTERS THE VOCABULARY references to "shelter" or "refuge" become more common A THEME IS ADDED OR STRENGTHENED "the hotel as sanctuary" joins the spine STYLE ATOMS DRIFT warmth +0.03 · pace −0.02 all changes within signed envelope
After a defining event, a literary character's voice is permanently inflected. Hamlet after the ghost. Anna after the train. The mechanism encoded here makes the same true for synthetic personas: the persona that has lived through your guests carries those guests' weight in its tone. This is the moat. A schema can be cloned. An accumulated narrative cannot.

07 dream → ship · the climb

v.01 static persona SHIPS NOW v.01 memory layer + 6–8 WEEKS v.01 affect layer + 3 MONTHS v.01 composition + 6 MONTHS v.01 narrative engine + 12 MONTHS v.01 living persona + 24 MONTHS v.01 cultural library + 36–48 MONTHS
Ship the simplest useful slice first. Demonstrate the architecture in print. v.01 is the public point where gosum becomes an open standard, governed in the commons, and ready to accumulate distinct stories.
