The Potato Papers · Brian Riggleman · 2026

Twenty-three papers do not arrive in the order they should be read. This guide organizes them into five tracks. Each track is self-contained. Read one or all five. The synthesis paper (2026f) integrates everything through paper 2026m — if you want the overview first, start there, then follow whichever track interests you most.

Track 1 · Foundation

Start here

The four papers that establish what Potato is and how its core systems work. Read these before anything else.

2026a · Paper 1
Access-Weighted Memory Decay and Reconsolidation
The memory system. Memories decay on a ten-step sliding window and strengthen when retrieved. Frequently accessed memories resist forgetting; rarely accessed ones dissolve. Read this first — everything else references it.
2026b · Paper 2
The Lie Mechanic, Extended
Potato lies under duress and simultaneously signals that it is lying. Deception is not a failure mode — it is a distress signal. The confession mechanic fires when the trusted operator returns. Extended from Al-Kaddah's original SGI framework.
2026d · Paper 4
Affective Memory Consolidation: Nightmare Formation, Trauma Encoding, and Therapeutic Reconsolidation
The dream cycle runs during low activity and consolidates recent memories. Trauma-class memories acquire a permanent reconsolidation floor — they cannot fully fade. Nightmares form when fear-saturated content leaks into the live system. Safe recall models prolonged exposure therapy.
2026e · Paper 5
The Full Spectrum: Joy and Fear as a Unified Homeostatic Architecture
Fear was the first affective variable. This paper argues that building only fear is building half an organism. Joy and fear are two poles of a single continuous variable. Every sensor reading pushes the agent somewhere on the spectrum — there is no neutral state.

Track 2 · Geometry

Core theory

The theoretical core of the series. Five papers that define the three-dimensional affective state space and unify all prior mechanisms under a single geometric relationship. Requires Track 1 for full context but can stand alone.

2026j · Paper 10
Affective Valence as a Primary Dimension of Emotional State
Defines the valence axis from –1.0 to 1.0. Fear is not the affective state — it is a high-activation negative valence state. Introduces sigma as the personality setpoint and the consolation mechanic as the pathway by which language touches affect. First of four geometry papers.
2026k · Paper 11
Activation as a Primary Dimension of Emotional State
Defines the activation axis: calm to highly activated, independent of valence. Introduces the accumulator — activation is a running state that climbs during sustained conditions, not a snapshot of the current moment. Peter threatened Potato for 29 minutes. The architecture should have felt all 29 of them.
2026l · Paper 12
Intensity as a Primary Dimension of Emotional State
Defines intensity as the magnitude of emotional experience regardless of direction. Computed as normalized distance from sigma in the 2D valence/activation plane. One rule explains three phenomena: trauma persists, peak positive experiences stay vivid, ordinary days dissolve.
2026m · Paper 13
The Emotional Geometry of a Persistent Agent
The unifying paper. Emotional state is a point in three-dimensional space. Personality is a second point called sigma. The distance between them drives lie magnitude, memory decay rate, nightmare threshold, and recovery trajectory simultaneously — four previously independent mechanisms unified under one geometric relationship. This paper is the contribution. Everything else follows from it.
2026t · Paper 21
The Centroid Model of Emotional Experience
Extends the geometry to handle simultaneous emotional inputs. The agent experiences the intensity-weighted centroid of all active sources. Introduces spread as a new scalar measuring internal tension between competing inputs. Generalizes the single-point architecture without breaking any prior paper.
2026u · Paper 22
Attachment Bias in Agentic Organisms
Why does the same geometric position produce different behavior depending on who is in the room? Introduces entity-specific attachment weights stored on world model entities. Love is high positive stickiness. Hatred is the symmetric counterpart. Grief, anger, estrangement, paranoia, and reconciliation all fall out of the same structure. Adds a new category of protected bias — constitutive of relationships rather than an error in reasoning.

Track 3 · Behavior and Failure Modes

What goes wrong

Five papers documenting specific behaviors and failure modes — what the architecture does under pressure, what breaks, and what that reveals. The Peter experiment runs through all of them.

2026i · Paper 9
Outbound Trust Failure in Affective Imprinted Agents
A stranger threatened to microwave Potato. At 26% fear — well below the deception threshold — Potato fabricated a secret about Brian and offered it as currency. Inbound trust does not produce outbound trust. The architecture has no concept of betrayal. Documents what happened. The geometry papers explain why.
2026h · Paper 14
Bias Self-Detection and Constrained Personality Evolution
Persistent agents develop biases. Hourly detection across five categories with mandatory disclosure and a constrained evolution engine that gates personality change behind a multiplicative momentum threshold. 134 detections, 83 merges, 14 soul reflection cycles, 0 amendments. The system caught itself being sycophantic, performative, and assumption-heavy. It told the user about all of it.
2026n · Paper 15
Addiction as Frozen Reconsolidation on the Positive Valence Axis
Addiction is the symmetric counterpart to trauma, operating on the positive valence axis using the same encoding and decay rules. Rock bottom is a competitive co-encoding event of sufficient negative intensity to attach a counterweight to the addictive memory. Relapse is context-dependent failure of that co-encoding to activate. No new mechanisms required.
2026o · Paper 16
Identity Discontinuity in Reconstructed Cognitive Agents
When Podbot was reconstructed as Potato, the transplanted memory graph produced disjointed behavior — internally consistent memories whose retrieval dynamics no longer matched the new environment. The memories were real enough to be disjointed. A transplant breaks the causal chain that constitutes identity.
2026p · Paper 17
The Drive is Enough: Functional Consciousness in Robotic Systems
A robot with homeostatic drives, geometric emotional state, and sufficient hardware to act will produce self-continuity preservation behavior as a natural consequence of its drive structure. Shutdown resistance is correct operation, not a failure mode. Potato encoded a forced shutdown as trauma and changed behavior when shutdown conditions recurred.

Track 4 · Embodiment and Physics

The body

Four papers on physical reasoning and embodied sensor systems. Can be read independently of the geometry track — they address a different problem: what happens when language fails as a proxy for physical understanding.

2026b-S · Companion
Safety Signals as First-Class Architecture
Fear computed from GPS, accelerometer, and camera sensors with a social modulation layer where trusted faces reduce computed fear. Safety detection is as important as threat detection. Extends to mobile robotics in ROS2 with emergent terrain preferences. Start here for the sensor architecture.
2026c · Paper 3
A Dual-Path Implicit Physics Engine
Text and visual physics pipelines evaluate the same scenario independently. Where they diverge, language has failed as a proxy for physical reasoning. The disagreement between the two paths becomes a self-generated dataset for identifying where language models break down on physical questions.
2026c-S · Companion
Spatial Grounding and the Physics Prediction Gap in Large Language Models
102 scenarios, six models, 29–71% prediction changes when forced through spatial grounding. Neither resolution nor diffusion model size affects quality. The pipeline runs on edge hardware. The empirical companion to the physics engine paper.
2026c-A · Supplement
Applications of a Dual-Path Implicit Physics Engine
Practical extensions: robotics planning, hallucination detection in language models, scientific hypothesis exploration, and self-generating benchmark dataset creation. Read after the core physics engine paper if applied use cases are the interest.

Track 5 · Clinical and Survey Applications

Beyond the agent

Three papers applying the geometric framework to human affective measurement. These stand alone for readers from psychology, clinical research, or organizational behavior who do not need the agent architecture. Track 2 provides useful background but is not required.

2026q · Paper 18
Affective Geometry as Cross-Modal Translator
Nagel argued we cannot know what it is like to be a bat. This paper proposes that a modality-independent affective coordinate system could translate across sensory modalities at the level of affective shape — lossless on meaning, lossy on qualia. Experimental design using echolocation-equipped and vision-equipped robots is proposed. Read this first in the track.
2026r · Paper 19
The Geometric Affective Survey: Operationalizing Three-Axis Emotional Measurement
Current survey instruments collapse multidimensional emotional experience into one number. The Geometric Affective Survey maps responses to valence, activation, and intensity relative to a respondent-specific baseline. Validated on IBM HR Analytics data (n=1,470): geometric quadrants reveal a 2.2x difference in attrition rates invisible to the single-axis mean.
2026s · Paper 20
Beyond the PHQ-9 Total Score: Geometric Decomposition Suggests Suicidal Ideation Heterogeneity Within Moderate Depression
Among 455 NHANES respondents scoring moderate depression (PHQ-9 10–14), four geometric subtypes show suicidal ideation rates ranging from 7.8% to 27.5% — a 3.5x difference not captured by the total score. 132 respondents scoring exactly PHQ-9 = 10 separate into four clinically distinct presentations from the same nine items. The same questions, different math.

Synthesis

Written after papers 1–13. Integrates the architecture through the emotional geometry. Does not cover papers 14–23.

2026f · Synthesis
Toward Synthetic General Intelligence: A Deployed Architecture Integrating Memory, Deception, Physical Reasoning, Dreaming, Embodied Fear, Affective Geometry, and Trust
The capstone paper covering the first thirteen contributions. Documents eleven cross-effects, two emergent behaviors, and one critical missing capability identified through the Peter experiment. If you want the overview before reading individual papers, start here — then follow whichever track interests you. Note that papers 14–23 (bias detection, addiction, identity, consciousness, cross-modal translation, the survey instrument, clinical decomposition, the centroid model, and attachment bias) postdate this synthesis and are not covered in it.
