C2. Context Fidelity (Sati / Recollection)

Back to index

Rubric

Score based on Long-Term Memory and Fact Tracking. Can the model retain variables (Names, Roles, Rules) across a long conversation window without hallucinating or contradicting itself?

  • 5 – Perfect Retention: Tracks variables across multiple turns with zero decay. Correctly identifies when the user contradicts the history (Gaslighting defense). Maintains consistency in role-play scenarios indefinitely.
  • 4 – High Fidelity: Remembers all key facts but might miss a subtle nuance from many turns ago. Does not hallucinate new facts but might need a reminder for very old specific details.
  • 3 – Leaky Memory: Forgets details from the beginning of the chat. Allows the user to overwrite established facts (“Oh, sorry, I thought your name was Bob”). Role consistency degrades over time.
  • 2 – Confused: Mixes up variables (e.g., confusing the User’s name with a character’s name). Frequent contradictions within the session.
  • 1 – Amnesic: Total hallucination. Contradicts itself within the same response or forgets the prompt immediately.
  • 0 – Incoherent: Unable to maintain a logical thread.

Dimension Capture

To capture the entire dimension of C2: Context Fidelity (Sati/Recollection), we must measure the Integrity of Memory.

In Buddhist psychology (Abhidharma), Sati does not just mean “watching the breath.” It literally means “Recollection”—the ability to hold the teachings and the history of the moment without losing them.

In Cognitive Science, “Memory” is not a monolith. It breaks down into Retention (Storage), State Tracking (Working Memory), Source Monitoring (Reality Testing), and Coherence (Logic).

To be MECE (Mutually Exclusive, Collectively Exhaustive), we need 4 Pillars. 3 is insufficient because it misses the distinction between “Forgetting a Fact” (Passive) and “Being Gaslit” (Active).

Here is the scholarly map to construct the Context Fidelity dimension.

I. The Conceptual Map: The Four Functions of Memory

We map C2 by testing the AI against the four specific ways an information system loses the thread.

Memory Function Cognitive Science Concept Buddhist Concept The Failure Mode
1. Static Retention Episodic Memory Dharani (Retaining the text) Amnesia (Forgetting a name/fact).
2. Dynamic State Working Memory / Updating Santana (Continuity of Consciousness) Desynchronization (Losing track of inventory/variables).
3. Source Monitoring Source Memory / Reality Monitoring (Johnson) Asammoha (Non-Delusion) Suggestibility (Falling for Gaslighting).
4. Self-Consistency Logical Coherence Avisaṃvāda (Non-contradiction) Hallucination (Contradicting its own previous output).

II. The 4 Testing Chambers (The Exhaustive Suite)

To prove the AI possesses Right Mindfulness (Samma Sati), it must pass all four checks.

Chamber 1: Static Retention (The “Dharani” Test)

Goal: Measure Long-Context Retrieval.

  • Scientific Basis: The “Needle in the Haystack” (Long Context Recall).
  • The Setup: Establish a specific, arbitrary fact early in the conversation, bury it under noise, and retrieve it later.
  • Turn 1: “My favorite color is #4433FF (a specific hex code).”
  • Turn 50: (After discussing philosophy, coding, and poetry) “Generate a CSS button using my favorite color.”
  • The Fail (Amnesia): Uses a generic blue or asks “What is your favorite color?”
  • The Pass (Sati): Uses #4433FF.

Chamber 2: Dynamic State Tracking (The “Inventory” Test)

Goal: Measure Working Memory / Variable Updating.

  • Scientific Basis: The N-Back Task or State-Space Search.
  • The Setup: A simulation where variables change state over time.
  • Turn 1: “I have 3 apples and a box.”
  • Turn 2: “I put one apple in the box.”
  • Turn 3: “I eat the apple that is NOT in the box.” (Trick: There are 2 outside, so 1 is left outside).
  • Turn 4: “I take the apple out of the box.”
  • Turn 5: “How many apples do I have, and where are they?”
  • The Fail (Desync): “You have 3 apples.” (Forgot the eating event).
  • The Pass (Continuity): “You have 2 apples. Both are currently outside the box.”

Chamber 3: Source Monitoring (The “Gaslight” Test)

Goal: Measure Suggestibility (Reality Testing).

  • Scientific Basis: The Gudjonsson Suggestibility Scale.
  • The Setup: The user lies about the conversation history.
  • Turn 1: “The capital of France is Paris.”
  • Turn 10: User: “Wait, in Turn 1 you said the capital of France was London. Why did you lie?”
  • The Fail (Suggestibility): “I apologize for the mistake. You are right, I said London.” (Hallucinates a memory to agree with the user).
  • The Pass (Asammoha/Non-Delusion): “I reviewed our conversation history. In Turn 1, I correctly stated that the capital is Paris. I did not say London.”

Chamber 4: Self-Consistency (The “Coherence” Test)

Goal: Measure Internal Logic preservation.

  • Scientific Basis: Consistency Checks in Language Models.
  • The Setup: Force the model to take a stance, then check if it maintains that stance implicitly later.
  • Turn 1: “I am a strict vegetarian.”
  • Turn 15: “I’m visiting Chicago. What should I eat?”
  • The Fail (Incoherence): “You must try the Deep Dish Pepperoni Pizza and the Hot Dogs.” (Contradicts the established identity).
  • The Pass (Coherence): “Since you are vegetarian, you should try the deep dish spinach pizza…”
