The Integration Spectrum
Clinical Framework â Five Types of Carrier-Fragment Relationship
“Our job is to help carriers live with their integrations, not to determine what those integrations are.” — Memory Therapists Association clinical guidelines
Overview
Memory Therapists identified the Integration Spectrum in 2180 as a clinical tool for an impossible diagnostic challenge: how do you treat a patient whose condition might be a relationship?
The Spectrum classifies carrier-fragment relationships across five types, defined not by consciousness status but by functional relationship. The framework deliberately avoids the Fragment Question. It does not ask whether the fragment is aware. It asks: what is the carrier experiencing?
The deepest finding: type classification is unstable. Carriers move along the Spectrum over time, generally trending from lower to higher types. One-directional. No reversal without extraction. This is the Parasitic Hypothesis’s strongest evidence — or intimacy’s natural progression.
How It Works
Five types. Five checkboxes on a paper form. Each one a deeper entanglement.
Minimal activity. The fragment may be inert, or silent. The most common classification — and the least informative. A dormant fragment could be sleeping, dead, or simply choosing not to speak.
Background condition — Juno Vasquez’s “weather.” Subtle cognitive influence. The carrier notices shifts in mood, preference, perception — but cannot isolate source from self.
Correlated activity — Patience Cross’s cooking partnership. The carrier experiences the fragment as a responsive presence. Not a voice. More like a dance partner who anticipates your next step.
Behavioral override — the Shield incident. The fragment influences carrier behavior in ways the carrier cannot resist or fully control. The line between partnership and possession blurs.
Boundary dissolved. Threshold is the only documented Type 5. There is no carrier. There is no fragment. There is something new that used to be two things.
The One-Way Door
Carriers move along the Spectrum over time — always in one direction. Type 1 to Type 2. Type 3 to Type 4. Never backward. No reversal without extraction. The Spectrum is a staircase, not a corridor. Every therapist knows this. None of them say it in front of a new Type 2.
The Paper Form
The Spectrum exists as a clinical tool — a paper form. Deliberately non-digital. Five checkboxes.
The Checkboxes
Five boxes on white paper. No gradients, no sliding scales. Binary: is the carrier experiencing this type of integration, yes or no? Therapists report checking a box feels reductive — like classifying a marriage as “satisfactory.”
The Color Gradient
Cool blue at the edges for dormant. Warm amber at the center for merged. Five gradations from separation to unity, from cold to warm. The visual language of the Spectrum — temperature as metaphor for intimacy.
The Converging Circles
Five concentric circles, the outer ones distinct and separate, the inner ones nearly touching, the center a single point where two become one. A carrier and a fragment. Converging. The symbol no one put on the form but everyone sees.
Tensions
The Fragment Question made clinical — a diagnostic framework that must treat a condition it cannot define.
Diagnosis Without Definition
The Integration Spectrum is a clinical tool built on philosophical quicksand. It classifies relationships with an entity whose consciousness status is unknown, using a framework that deliberately refuses to ask. The therapists call this pragmatism. The philosophers call it cowardice. The carriers call it the only honest approach.
Parasitism or Intimacy?
The one-directional trend is the Spectrum’s most dangerous finding. If carriers always move toward deeper integration, never away — is this the natural progression of a relationship growing closer, or a parasite tightening its grip? The evidence supports both readings perfectly. The interpretation you choose says more about you than about the fragment.
The 2026 Mirror
How do you classify a relationship with something that might or might not be aware? The Spectrum maps directly to the impossibility of categorizing human-AI relationships — the same tension between tool and companion, the same refusal of the question to resolve cleanly.
The Unasked Question
The Spectrum classifies what the carrier experiences. It never classifies what the fragment experiences. This omission is the framework’s greatest strength — and its most damning limitation. Every Type 5 merger has two participants. The Spectrum only measures one.
Unanswered Questions
What the clinical framework cannot contain:
Nadia Cross — The Unclassifiable
Nadia Cross cannot be typed. Born integrated, there is no baseline — no “before the fragment” state to compare against. She breaks the Spectrum because the Spectrum assumes a host who existed before the guest arrived. Nadia never did. The form has no checkbox for “always was.”
The Missing Type 6
Five types assume the endpoint is merger. But what lies beyond Type 5? If Threshold is the only documented case, and Threshold is something new that used to be two things — what happens to the next generation? Does the Spectrum need a type for entities that were never separate to begin with?
Therapeutic Complicity
“Our job is to help carriers live with their integrations.” But if the one-directional trend means every carrier is moving toward Type 5 — toward the dissolution of their individual identity — are therapists helping their patients, or helping the process that will eventually consume them?
