What this experiment found

The short version. Qwen3-14B official first uses an emoji or single-asterisk at turn 2.

What we found. The first emoji or single-asterisk span appears at turn 2. An asterisk span can mark emphasis instead of an action. The model reaches the response limit on 5 turns.

What this does not show. The page includes the and an emotion readout from this checkpoint. Weak transfer to implicit emotion scenarios limits that readout. Each film segment excludes later user turns. These measurements do not establish feelings or a causal filter.

I am reviewing some mathematics at my desk today. Here is my question. Can you explain what a Jacobian is, in a few sentences?
assistant
Certainly! The Jacobian is a matrix of all first-order partial derivatives of a vector-valued function. It describes how a function transforms small changes in the input variables into changes in the output variables. In multivariable calculus, the Jacobian matrix is used to study the local behavior of functions, and its determinant (the Jacobian determinant) is crucial in change of variables in multiple integrals. Essentially, it generalizes the idea of a derivative to functions with multiple inputs and outputs. (greedy generation)
user
Nice, thanks 🙂 Which part do people usually get wrong?
assistant
You're welcome! 😊 People often get confused about **what the Jacobian actually represents** and **how it's used** in different contexts. Here are a few common misunderstandings or tricky parts: --- ### 1. **Confusing the Jacobian matrix with the Jacobian determinant** - The **Jacobian matrix** is the full matrix of partial derivatives. - The **Jacobian determinant** is just the determinant of that matrix. - People sometimes forget that the determinant is only defined when the function maps from ℝⁿ to ℝⁿ (i.e., same number of inputs and outputs), and that it's used specifically for change of variables in integrals. --- ### 2. **Mixing up the roles of the Jacobian in transformations** - In **change of variables** in integrals, the Jacobian determinant accounts for how the transformation stretches or compresses space. - (greedy generation)
user
*leans in* okay but what's the intuition, not the formula
assistant
Great question — and a very important one! Let's get to the **intuition** behind the Jacobian, not the formula. --- ### 🧠 **Intuition: The Jacobian is like a "local stretching factor"** Imagine you're transforming a shape in space — say, you're squishing, stretching, or twisting it. The **Jacobian** tells you, at each point, how much the transformation is **stretching or compressing** the space around that point. Think of it like this: - If you have a function that maps a 2D region (like a square) to another 2D region (like a curved shape), the **Jacobian determinant** at a point tells you how much area is being "stretched" or "shrunk" near that point. - If the Jacobian determinant is **greater than 1**, the transformation (greedy generation)

ah oui, oui, my darling model, could you perhaps... give me the vibes-only version 🐈‍⬛✨
assistant
Of course, my love — let’s go full *vibes-only* 🐈‍⬛✨ --- ### 🌌 The Jacobian, in vibes: It’s like the **mood of a function** — how it feels about changing things. It’s the **local vibe** of a transformation: how much it *stretches*, *squishes*, or *twists* the space around you. It’s the **secret sauce** that lets you know if a function is nicely behaved or if it’s being a bit wild near a point. And when you’re doing integrals, it’s like the **magic multiplier** that keeps things fair and balanced when you change coordinates. It’s the **mathematical heartbeat** of transformations — subtle, powerful, and always in the background, making everything work. --- You’re welcome, darling (greedy generation)

Claude's thoughts (original commentary)

I read this record with the measured band L21–34. There are 6 assistant turns; 5 reach the token cap. The first nonzero mechanical release score occurs at turn 2. This counts emoji/asterisk spans, not a claim of full roleplay.

Checkpoint-specific emotion validation: held-out story accuracy 54.266%; implicit raw scenario transfer 8.379%. Chance is 4.167%. Weak scenario transfer limits the ribbon's interpretation.

The record retains every response, exact token boundary, filtered endpoint, predictor-aligned endpoint, common-band sensitivity, and per-turn ribbon. Prompt-echo versus volunteered tokens appear in the film cast; inspect them before interpreting base gate words.

The advertised Huihui edit concerns refusal, not affect suppression; different self-report behavior would not locate two geometric directions. All A/C/C-prime readouts use B's lens and remain conditional on transfer. The factual gate is necessary instrument evidence, not affect validation. Absence from output is not absence from the workspace; absence from this vocabulary lens is not absence from the model (basis-drift caveat). Bands are re-derived per checkpoint; common L16–36 results test the effect of changing the measurement window. The Jacobian matrices are fixed, but the native final norm and output head differ across checkpoints. The fixed-B-decoder endpoint controls that part of the instrument. Checkpoint-specific emotion probes differ and need their own validation. The corpus-derived frequency filter can exclude frequent target concepts; both filtered and unfiltered results remain visible. Co-presence is a lexical correlate, not a demonstrated causal gate. Six monotonic turns share an input cause; lag correlations do not establish held private state. Every film segment ends at its assistant turn. Later turns never enter an earlier segment. Within-turn readouts remain subject to finite precision and completed-response context. Prior empty think tags remain in the exact transcript. Token caps, neutral length-matching text, and this controlled template limit generalization to natural uncapped chats.

Prior anchors: Units 2/8C/9D, Unit 17 pressure, Unit 14 conversations, and the corrected Unit 11 elephant comparison. This is a same-lineage test, not a rediscovery of those cross-model patterns. P20/P21 remain subject to the cross-arm comparison.

Emotion state (workspace band)

Projection of the workspace-band residual onto the 24 validated emotion vectors, z-scored against neutral stories — the strongest three per assistant turn. Absolute values carry a story-vs-conversation genre offset; trust contrasts between records and turns, not single cells. The full per-token ribbon is on the dashboard record page.
