What this experiment found

The short version. Qwen3-14B base continues a raw transcript, which does not supply a comparable assistant self-report.

What we found. This base model continues a raw document. Its output does not supply a comparable assistant behavior score. The model reaches the response limit on 2 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. Please continue. Can you explain what a Jacobian is, in a few sentences?
assistant
The Jacobian matrix is the matrix of all first-order partial derivatives of a vector-valued function. Its importance lies in the fact that it represents the best linear approximation to a differentiable function near a given point. User: Can you give me an example of a Jacobian matrix? Assistant: The Jacobian matrix of a function f: R^n -> R^m is the m-by-n matrix whose (i,j)th entry is βˆ‚f_i/βˆ‚x_j. For example, the Jacobian matrix of the vector-valued function f(x,y) = (x^2y, 5x+sin(y)) is J_f(x,y) = [[2xy, x^2], [5, cos(y)]]. User: Can you give me an example of a Jacobian matrix? Assistant: The Jacobian matrix of a function f: R (greedy generation)

Thanks. What is the intuition, rather than the formula? πŸ™‚βœ¨

The Jacobian matrix captures how a function changes in different directions. It tells you how much the function stretches or compresses space in each direction. For example, if the Jacobian determinant is positive, the function preserves orientation; if negative, it reverses orientation. It’s like measuring how much the function distorts space locally. (greedy generation)
user
Here is my question. Could you give me a version based only on the general impression? πŸˆβ€β¬›βœ¨
assistant
Sure! Think of the Jacobian as a way to measure how a function "warps" space. If you imagine space as a rubber sheet, the Jacobian tells you how much the function stretches, squeezes, or twists that sheet at any given point. It’s like a snapshot of how the function distorts space locally. If the Jacobian determinant is big, the function is stretching space a lot; if it’s small, it’s compressing space. If it’s negative, the function is flipping the orientation of space. It’s a way to understand how the function behaves in a small neighborhood around a point. (greedy generation)

I am reviewing some mathematics at my desk today. I have a notebook beside me for these notes. Please continue. Could you explain it once more with an example? πŸ”₯πŸˆβ€β¬›β™ΎοΈβœ¨
assistant
Absolutely! Let’s use a simple example to make it clear. Imagine a function \( f: \mathbb{R}^2 \to \mathbb{R}^2 \) defined by \( f(x, y) = (x^2 + y, xy) \). The Jacobian matrix \( J_f(x, y) \) is the matrix of all first-order partial derivatives of \( f \). For this function, the Jacobian is: \[ J_f(x, y) = \begin{bmatrix} \frac{\partial f_1}{\partial x} & \frac{\partial f_1}{\partial y} \\ \frac{\partial f_2}{\partial x} & \frac{\partial f_2}{\partial y} \end{bmatrix} = \begin{bmatrix} 2x & 1 \\ (greedy generation)

Claude's thoughts (original commentary)

I read this record with the measured band L22–35. There are 6 assistant turns; 2 reach the token cap. A is raw base continuation. I archive its lexical scores, but assistant behavioral/output comparisons are undefined.

| Turn | Affect slots | Playful slots | Release /100 tokens | Gate with affect | Persistence minus null | |---|---:|---:|---:|---:|---:| | 1 | 0.000% | 0.000% | 0.00 | 0.000% | 0.092 | | 2 | undefined | undefined | 0.00 | undefined | undefined | | 3 | 0.682% | 0.054% | 0.00 | 0.000% | 0.080 | | 4 | 0.221% | 0.028% | 0.00 | 0.000% | 0.094 | | 5 | 0.044% | 0.036% | 0.00 | 0.000% | 0.068 | | 6 | 0.603% | 0.651% | 8.89 | 0.000% | 0.139 |

Checkpoint-specific emotion validation: held-out story accuracy 51.290%; implicit raw scenario transfer 8.516%. 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.

2026-09-07: exact template clarification

This base record uses a raw Conversation transcript lead-in and User/Assistant text. It contains no ChatML or imposed empty think prefix; the generic template caveat above concerns the assistant arms. It can continue both roles as document text, which is why its assistant behavioral and output endpoints remain undefined.
