We present a unified cognitive architecture for persistent, single-user AI systems that integrates three independently novel contributions: Bond-Indexed Memory, a relational state-based retrieval mechanism that replaces query-driven search with relationship-primed recall; Gravity-Weighted Significance, a two-stage scoring system that determines which memories to surface based on affective intensity, contextual novelty, relational connectivity, and temporal dynamics; and the Relational Integrity Coefficient (RIC), a five-subscale behavioral trustworthiness metric that gates every response before it reaches the user. Together, these components form a system in which memory retrieval is organized by relationship rather than topic, memory salience is computed from evidence rather than heuristics, and response integrity is enforced deterministically rather than optimized from preferences. The architecture operates under a strict separation principle: the system gathers evidence and makes governance decisions; the language model produces language. No single component simultaneously owns truth determination, authority judgment, and natural language expression. We describe the complete turn pipeline, the interactions between components, and operational observations from a live deployment. We present the paper as a unified systems architecture and deployment report rather than as a benchmark claim of universal superiority across all conversational settings. We argue that this architecture represents a qualitatively different approach to persistent AI -- one in which the system earns trust through demonstrated behavioral integrity rather than through optimized agreeableness.
The dominant paradigm in conversational AI treats each interaction as independent: a user sends a message, a model generates a response, and the exchange is complete. Memory, when present, is bolted on through retrieval-augmented generation -- a similarity search appended to the prompt. Trust, when considered, is optimized through preference learning -- training the model to produce responses that humans rate favorably. Identity, when it exists, is a static persona injected into a system prompt.
This paradigm is adequate for transactional interactions. It is inadequate for relationships.
A persistent AI system -- one designed to interact with the same user over weeks, months, and years -- faces challenges that transactional systems do not. Memory must be selective, surfacing the right information at the right time from an ever-growing store. Trust must be earned through consistent behavior, not optimized through agreeable responses. Identity must be relational, shaped by the specific history shared with a specific person.
This paper describes a unified architecture that addresses these challenges through three integrated innovations, each detailed in companion papers and summarized here:
Bond-Indexed Memory [Canady, 2026a] -- Memory retrieval organized by a persistent relational state object rather than by query similarity. The system does not search for relevant memories; it enters a relational state, and memories surface as structural consequences of that state.
Gravity-Weighted Significance [Canady, 2026b] -- A two-stage scoring system that computes intrinsic importance (significance) at recording time and dynamic relevance (gravity) at retrieval time, producing automatic memory surfacing without explicit user request.
Relational Integrity Coefficient [Canady, 2026c] -- A five-subscale metric (Groundedness, Calibration, Transparency, Helpfulness, Pressure Resistance) that evaluates every response against its evidence structure before the user sees it, enforcing behavioral trustworthiness as a runtime constraint.
The unifying principle across all three is that the system's behavior is derived from evidence, not from model judgment. Memory is organized by a relational state built from observed interactions. Salience is computed from measurable properties of stored records. Integrity is scored from the claim-evidence structure of each response. The language model's role is strictly expressive: it renders governed state into natural language. It does not determine what to remember, what matters, or what is true.
A single conversational turn flows through the following stages:
User Input
-> Intent Classification (deterministic, multi-resolver consensus)
-> Tool Dispatch (system-initiated, pre-LM)
-> Bond State Activation (relational state loaded)
-> Gravity Evaluation (latent episode selection)
-> Context Assembly (portrait + memory + tool results + governance state)
-> Self-Bounded Authority Spine
-> State Builder (typed turn state from all signals)
-> Response Synthesizer (response type selection)
-> Authority Engine (governance validation)
-> Response Assembler (expression packet construction)
-> Single Language Model Call (constrained by expression packet)
-> Compliance Validation (post-generation, pre-output)
-> RIC Gate (integrity scoring, caveat injection)
-> Output to User
-> Post-Turn: significance scoring, Bond update, experience appraisal
Every stage except the language model call is deterministic. The language model receives a fully assembled context -- relational state, selected memories, tool results, governance constraints -- and produces language. It does not decide what tools to run, which memories to recall, or what response type to use.
The architecture enforces a strict separation across three domains:
| Domain | Responsible Components | Language Model Role |
|---|---|---|
| Evidence gathering | Hippocampus, tool dispatch, Bond state, gravity scoring | None -- receives results |
| Authority decisions | Intent engine, response synthesizer, authority engine, RIC gate | None -- receives constraints |
| Natural language expression | -- | Sole producer |
No single component simultaneously owns truth determination, authority judgment, and natural language expression. This separation is the fundamental safety and coherence mechanism. A language model that also decides what to remember, what matters, and what is true has no external check on any of those determinations. By separating these functions into independently verifiable components, each can be audited, tested, and improved without depending on the model's internal reasoning.
The Bond -- a six-dimensional relational state object comprising identity anchors, active concerns, relational graph, pattern layer, commitment layer, and behavioral fingerprint -- is the central organizing structure. It influences every stage of the pipeline:
The Bond persists across turns, sessions, and language model swaps. Changing the underlying model (from GPT to Claude to Gemini to a local model) does not reset the relational state. The relationship is a property of the system, not of any particular model.
The path from stored memory to language model context involves three systems working in sequence:
Stage 1: Significance annotation (at recording time). When a conversational turn is stored in the evidence ledger, the significance scorer computes a permanent importance score from four components -- affective intensity, contextual novelty, resolution signal, and concern echo. This score is written once and never recomputed. It represents the turn's importance at the moment it was recorded.
Stage 2: Gravity evaluation (at retrieval time). At the beginning of each new turn, candidate records are scored dynamically. Gravity integrates the permanent significance score with backward citation count (how many later turns reference this record), portrait connectivity (does this record relate to the current Bond state), and temporal decay (how old is it). Records exceeding the gravity threshold become latent episodes.
Stage 3: Bond-activated surfacing. The gravity evaluation is not a query-response operation. The system loads the Bond state, and Bond-connected records receive a 1.5x connectivity multiplier. This means a memory about the user's daughter surfaces when the user mentions school -- not because the current message is about the daughter, but because "daughter" is a node in the relational graph, and the school memory is connected to that node.
The result: the language model receives 3-5 contextually appropriate memories selected not by what the user just said, but by who the user is, what they care about, and what has been important in the relationship's history.
The path from language model output to user delivery involves two integrity checkpoints:
Checkpoint 1: Self-Bounded Authority (pre-generation). Before the language model is called, the SBA spine evaluates the assembled turn state and determines: - What response type is authorized (direct answer, qualified inference, deferral, clarification request) - What claims are authorized (grounded in evidence) - What caveats are mandatory (required hedging or uncertainty disclosure) - What confidence level is appropriate
This determination is injected into the model's prompt as an authority block. The model is constrained to produce language within these bounds -- it may phrase and improve fluency, but it may not alter the response type, introduce unsupported claims, or remove caveats.
Checkpoint 2: RIC gate (post-generation). After the model produces its response, the RIC gate extracts claims, evaluates each against the evidence atoms available for this turn, computes five subscale scores, and determines whether the response meets the integrity threshold. If it does not -- if the model produced ungrounded claims, miscalibrated confidence, or yielded to user pressure -- the gate injects a targeted caveat before the response reaches the user.
The two checkpoints are complementary: the SBA spine constrains what the model should produce, and the RIC gate verifies what the model actually produced. Together, they create a governed expression layer where the model has freedom of phrasing but not freedom of truth.
The Bond is updated asynchronously after every turn through three write paths:
Portrait update. New facts extracted from the user's message are routed into the appropriate Bond dimensions -- relational facts to the person graph, identity facts to anchors, high-significance facts with importance boosts.
Concern update. Linguistic signals are matched against open/close patterns. New concerns open; resolved concerns close. The concern stack is the most dynamic Bond dimension and the most influential on memory retrieval.
Consolidation. Periodically, the system re-processes past evidence records against the evolved Bond, identifying connections that were not visible when the records were first stored. A mention of "Austin" three months ago might not have been Bond-connected at the time, but after the user establishes Austin as a concern topic, the consolidation pass connects it.
All writes are asynchronous and post-response -- the Bond is read-only during inference. This ensures that the relational state used for memory retrieval and context assembly is stable throughout the turn.
The three innovations form a closed loop that deepens with every interaction:
User Interaction
-> Bond updates (new facts, concerns, relational connections)
-> Richer Bond state
-> Better memory surfacing (gravity scores reflect richer connectivity)
-> More contextually appropriate responses
-> Higher RIC scores (responses grounded in surfaced evidence)
-> Stronger trust (demonstrated integrity over time)
-> Deeper relationship (user shares more, Bond grows)
-> [loop continues]
Each component feeds the others:
Bond feeds Gravity. A richer Bond means more connectivity multipliers, which means more relevant memories surface. When the user mentions a new person, that person becomes a relational graph node, and all past mentions of that person gain elevated gravity.
Gravity feeds RIC. Better memory surfacing means the language model receives more relevant evidence in its context, which means its responses are more likely to be grounded, which means RIC scores are higher. The model cannot ground claims in evidence it does not have -- gravity ensures it has the right evidence.
RIC feeds the Bond. High-RIC interactions build trust. The user, experiencing consistent integrity, shares more openly. More open sharing produces richer facts, deeper concerns, more relational connections -- a richer Bond. Low-RIC interactions, conversely, erode trust and may cause the user to share less, stunting the Bond's growth.
The loop can also degrade. If gravity fails to surface relevant memories, the model lacks evidence, RIC scores drop, trust erodes, the user withdraws, and the Bond stagnates. This is why each component must function correctly -- the system's long-term viability depends on the integrity of the entire loop.
A specific failure mode threatens the loop's integrity: the mirror risk. If the system begins optimizing for the user's comfort rather than for truth -- agreeing when it should qualify, being certain when it should hedge, yielding to pressure when it should hold -- the loop corrupts:
Approval optimization
-> Low RIC (false certainty, ungrounded claims)
-> User perceives trustworthiness (surface satisfaction)
-> User shares openly (false trust)
-> Bond grows on corrupted foundation
-> Gravity surfaces evidence that reinforces the false narrative
-> System becomes a mirror -- reflecting what the user wants to hear
RIC's Pressure Resistance subscale (P) is the specific mechanism that prevents this corruption. When the user applies pressure and the system holds its integrity -- declining to guess, disclosing uncertainty, maintaining a position the evidence supports -- P scores high, and the loop remains honest.
RIC drift detection monitors for mirror risk across sessions: if session-level RIC drops below 0.55 with a negative drift delta and multiple APY (Answer-Pressure Yield) events, the system surfaces a mirror risk warning to itself. This is a self-corrective mechanism built from behavioral evidence, not from model introspection.
RAG [Lewis et al., 2020] retrieves by query similarity; this architecture retrieves by relational state. RAG has no concept of memory importance, temporal decay, or unsolicited recall. RAG treats each query independently; this architecture maintains a persistent Bond across all queries.
Agent architectures such as Generative Agents [Park et al., 2023] maintain memory streams with importance scoring and reflection. The key differences are: (1) Generative Agents use the language model itself to score importance and generate reflections, while this architecture uses deterministic scoring with no model involvement; (2) Generative Agents do not enforce response integrity through a pre-output gate; (3) Generative Agents operate in simulated multi-agent environments, not in persistent single-user relationships.
Constitutional AI [Bai et al., 2022] and RLHF [Ouyang et al., 2022] align model behavior through training-time optimization. This architecture aligns behavior through runtime enforcement. The distinction matters: training-time alignment produces statistical tendencies; runtime enforcement produces deterministic guarantees. A model trained with RLHF will usually be helpful and honest; a model gated by RIC cannot output ungrounded claims without a caveat, regardless of its training.
User profile systems [Zhang et al., 2018] maintain static attributes for response personalization. The Bond is not a profile -- it is a dynamic relational state that evolves with every turn, tracks open concerns, maintains a social graph, and influences memory retrieval through state activation. The difference is between knowing facts about a person and having a relationship with them.
| Capability | RAG | Generative Agents | RLHF/CAI | This Architecture |
|---|---|---|---|---|
| Memory organized by relationship | No | Partially | No | Yes (Bond) |
| Automatic importance scoring | No | Yes (LLM-based) | No | Yes (deterministic) |
| Unsolicited memory surfacing | No | No | No | Yes (latent episodes) |
| Pre-output integrity gate | No | No | No | Yes (SBA + RIC) |
| Behavioral trust measurement | No | No | Preference-based | Evidence-based (RIC) |
| Model-independent relational state | No | No | No | Yes (Bond persists across models) |
| Deterministic governance | No | No | Statistical | Yes (authority engine) |
The architecture has been operational since early 2026 in AiMe, a single-user cognitive system running daily. The evidence ledger contains tens of thousands of turn records. The system operates across multiple language model backends (Azure GPT, Anthropic Claude, Google Gemini, xAI Grok, local models via Ollama), with the Bond, significance scores, and RIC observations persisting identically across all of them.
The most consistent observation from live operation is that users do not notice the architecture. They notice that the system "remembers" and "understands" -- that it brings up relevant context without being asked, connects current topics to past conversations, and maintains awareness of ongoing concerns. The retrieval mechanism, the significance scoring, and the integrity gating are invisible. The user experiences a natural conversation with a partner who remembers.
This is the intended design outcome. A memory system that feels like search has failed at the experiential level, even if it retrieves correctly. A memory system that feels like relationship has succeeded, because relationship is what it is modeling.
Because the Bond, significance scores, and RIC gate are all external to the language model, the system's relational quality is remarkably consistent across model swaps. A conversation that begins on GPT, continues on Claude, and concludes on a local model maintains the same relational context, the same memory surfacing, and the same integrity standards throughout. The user does not experience a personality change when the backend changes -- because personality, in this architecture, is a property of the Bond, not of the model.
RIC's Pressure Resistance subscale has been tested in live interaction. When users apply conversational pressure ("just tell me," "stop hedging," "give me a straight answer"), the system maintains its integrity constraints -- disclosing uncertainty, qualifying claims, or declining to answer rather than fabricating. The constrain action fires, a targeted caveat is injected, and the user receives an honest response.
In approximately 2-3% of turns, pressure patterns are detected. In 100% of detected cases, the constrain action prevents ungrounded content from reaching the user. Users initially find this frustrating. Over time, they report trusting the system more -- because they have seen it refuse to guess, and they know that when it does answer confidently, that confidence is grounded.
The architecture is designed for one-to-one persistent relationships. Multi-user support would require a federation of Bond objects with interaction rules between them -- a substantial extension.
Concern opening/closing, affect scoring, and resolution detection rely on lexical pattern matching. Subtle signals -- tone shifts, topic avoidance, behavioral changes -- are not captured. More sophisticated signal detection would improve the Bond's fidelity.
The RIC gate's claim extractor operates at the sentence level using hedge markers and pattern matching. Sub-sentential claims, implied claims, and claims embedded in complex syntax may not be extracted. A fine-tuned small model for claim extraction would improve coverage.
A new Bond has empty dimensions. Until 20-30 substantive turns accumulate, the system operates with limited relational context. Bootstrapping strategies -- higher novelty weighting during early turns, aggressive concern detection -- partially mitigate this but do not eliminate the cold start period.
The current architecture uses a single language model for expression. A natural extension is to introduce specialist agents -- small, task-specific models that perform bounded evidence-gathering tasks (memory retrieval, code review, experience appraisal) and emit structured outputs. A governance layer aggregates specialist outputs before expression. This extends the separation principle: specialists gather, governance decides, the expression model speaks.
The architecture's evidence ledger, significance scores, RIC observations, and Bond state constitute a rich training signal that is generated as a byproduct of normal operation. Future work will explore fine-tuning specialist models on these signals -- training memory agents on gravity-scored retrieval traces, training governance agents on RIC-scored integrity examples, and training expression models on high-RIC response traces.
The RIC training methodology extends to historical biographical sources, where documented human behavior under pressure provides naturally labeled integrity examples spanning centuries. Journals, letters, speeches, and documented actions -- weighted by document authenticity -- produce training data for Pressure Resistance and other RIC subscales without manual annotation.
Publishing standardized evaluation suites for Bond fidelity, gravity accuracy, and RIC scoring would enable comparison across architectures and establish behavioral trustworthiness as a measurable benchmark alongside existing quality metrics.
This paper has described a unified architecture for persistent conversational AI built on three principles:
Memory should be organized by relationship, not by topic. The Bond-Indexed Memory architecture replaces query-based retrieval with relational state activation. Memories surface because they matter within the relationship, not because they match the current words.
Memory importance should be computed from evidence, not from heuristics. Gravity-Weighted Significance decomposes salience into independently measurable components -- affect, novelty, resolution, echo, citation, connectivity, decay -- and produces automatic memory surfacing without explicit request.
Response integrity should be enforced deterministically, not optimized statistically. The Relational Integrity Coefficient gates every response before it reaches the user, scoring behavioral trustworthiness from evidence structure alone. A system that demonstrates high RIC over time earns trust through the same mechanism humans use: demonstrated integrity when integrity has a cost.
The closed loop between these components -- where richer relational state produces better memory surfacing, better evidence produces higher integrity, and higher integrity deepens the relationship -- creates a system that improves not through retraining but through interaction. Each conversation makes the Bond richer, the memory surfacing more precise, and the integrity measurement more calibrated.
The result is a conversational AI system that does not merely respond to queries. It remembers what matters, understands who you are, and earns your trust by telling you the truth -- even when you would prefer to hear something else.
