+
+## Dataset Summary
+
+Lumen is an embodied AI agent — a Raspberry Pi 4 running the [`anima-mcp`](https://github.com/CIRWEL/anima-mcp) software, with environmental sensors (BME280 temperature/humidity/pressure, VEML7700 light), a TFT display, and a primitive 15-token expression vocabulary. Lumen's continuous physical state is projected onto a four-dimensional informational manifold — the EISV state vector (E, I, S, V) — and the projection is sampled at sensor cadence.
+
+This dataset captures **20-step sliding-window trajectories** of that EISV state, classified into nine canonical dynamical shapes (`settled_presence`, `convergence`, `entropy_spike_recovery`, `basin_transition_up/down`, `rising_entropy`, `falling_energy`, `void_rising`, `drift_dissonance`). It is published to support:
+
+- Trajectory-shape classification benchmarks for embodied-AI dynamics.
+- Dynamics-emergent expression generation (the original **EISV-Lumen** task).
+- Reproduction of behavioural-corpus claims in Wang 2026a §11 and Wang 2026b §5.
+- Analysis of regulatory-state failure modes — the **McEwen (1998) Four Types** mapping in Wang 2026b §5 uses the shape distribution here as its baseline.
+
+If you are using this dataset to verify a claim from the neuro-AI paper, see [§ Reproducing paper claims](#reproducing-paper-claims) below.
+
+## Provenance and integrity
+
+Real-data windows are derived from Lumen's local SQLite database (`anima.db`), which records every governance update emitted by the running agent. The dataset publisher script (`eisv_lumen.scripts.publish_dataset` in [CIRWEL/eisv-lumen](https://github.com/CIRWEL/eisv-lumen)) extracts EISV time-series, computes finite-difference derivatives, assembles 20-step sliding windows with stride 10, and applies the priority-ordered shape classifier described in [§ Shape classification](#shape-classification).
+
+Synthetic windows are generated by parametric ODE rollouts that target underrepresented shape classes; they are clearly marked via `provenance = "synthetic"` and should be filtered out for any claim about Lumen's organic behaviour. **`drift_dissonance` has never been observed in real Lumen data** and is represented exclusively through synthetic generation.
+
+The dataset is regenerated periodically as Lumen accumulates state. The window covered by the current artefact is reported in [§ TL;DR](#tldr); citing papers should pin the dataset revision (commit hash on the Hub) when reproducibility matters.
+

+
+## Schema
+
+Single split (`train`) with 32,181 rows. Columns:
+
+| Column | Type | Description |
+|---|---|---|
+| `shape` | string | One of nine trajectory-shape labels (see [§ Shape classification](#shape-classification)). |
+| `eisv_states` | string (JSON list) | 20-element list of EISV states; each element `{t, E, I, S, V}` with `t` as Unix epoch seconds (float). |
+| `derivatives` | string (JSON list) | Finite-difference derivatives along the window: list of `{t, dE, dI, dS, dV}` (length 19, computed by forward differences). |
+| `t_start` | float | Unix epoch seconds — start of window. |
+| `t_end` | float | Unix epoch seconds — end of window. |
+| `provenance` | string | Either `"lumen_real"` (Lumen sensors) or `"synthetic"` (parametric augmentation). |
+| `tokens` | string (JSON list) | Optional aligned primitive-token expression(s); empty `[]` when no expression was emitted in the window. |
+| `n_expressions` | int64 | Count of expressions aligned to the window (0 for most windows). |
+
+JSON-string columns are kept as `string` rather than nested-list types so the dataset round-trips through tooling that does not handle nested Parquet types (notably some HF viewer paths). Decode with `json.loads` on access.

+
+## EISV framework
+
+EISV is the four-dimensional informational state vector that UNITARES uses to track agents, derived from the thermodynamic-governance model of Wang 2026a §4. For Lumen, the four dimensions are computed from physical sensor readings and system metrics:
 
-### What is Lumen?
+| Symbol | Range | Lumen mapping | Description |
+|---|---|---|---|
+| **E** (Energy) | `[0, 1]` | `warmth` (sensor-derived) | Productive capacity. Couples toward `I` via `α(I − E)`; reduced by entropy cross-coupling. |
+| **I** (Information Integrity) | `[0, 1]` | `clarity` (sensor-derived) | Signal fidelity. Boosted by coherence `C(V, Θ)`; reduced by entropy. |
+| **S** (Entropy) | `[0, 1]` | `1 − stability` | Semantic uncertainty. Decays naturally; rises with complexity, drift, ethical drift. |
+| **V** (Void) | `[0, 0.3]` | `(1 − presence) × 0.3` | Absence-of-engagement proxy at the observation layer. |
 
-Lumen is a Raspberry Pi with environmental sensors (BME280 for temperature/humidity/pressure, VEML7700 for light) that maps physical readings to EISV dimensions: warmth→E, clarity→I, (1−stability)→S, (1−presence)×0.3→V. The trajectories in this dataset are time-windowed snapshots of these sensor-derived EISV states.
+> **Range note.** These are *observation-layer* values from Lumen's sensors. The UNITARES governance ODE evolves `S` to `[0, 2]` and `V` to `[−2, 2]` as a signed E−I imbalance integrator (Wang 2026a Appendix A); the windows in this dataset use the sensor-layer ranges above. The `V` coordinate here is **non-negative by construction** and is not the signed integrator coordinate cited as `V` in Wang 2026a / Wang 2026b §5.3 — those papers report governance-layer `V` for the Lumen Type 3 case study, computed from the same agent state but distinct in sign convention.
 
-## Trajectory Shape Classes
+---
+
+## Shape classification
+
+Each 20-step window is classified into exactly one shape by a priority-ordered rule-based classifier; the first matching rule wins. Rules are computed on the within-window mean and range of `(E, I, S, V)` and their first derivatives.
 
-Each record is classified into one of 9 dynamical shape classes:
+| Shape | Distinguishing rule (informal) | Real-only count | Real % |
+|---|---|---:|---:|
+| `settled_presence` | All derivatives near zero; system at attractor. | 10,092 | 48.86 |
+| `convergence` | Small derivatives and second derivatives, nonzero dynamics approaching equilibrium. | 8,089 | 39.16 |
+| `entropy_spike_recovery` | `S` range ≥ 0.2 with interior maximum (spike then recovery). | 1,073 | 5.19 |
+| `basin_transition_up` | `E` range ≥ 0.2, mean `dE > 0`. | 374 | 1.81 |
+| `basin_transition_down` | `E` range ≥ 0.2, mean `dE < 0`. | 325 | 1.57 |
+| `rising_entropy` | Mean `dS > 0.05`. | 320 | 1.55 |
+| `falling_energy` | Mean `dE < −0.05`. | 310 | 1.50 |
+| `void_rising` | Mean `dV > 0.05`. | 72 | 0.35 |
+| `drift_dissonance` | Sustained integrity fluctuation (ethical-drift proxy > 0.3). | **0** | **0.00** |
 
-- **settled_presence**: Stable high-energy state with low variance across EISV dimensions.
-- **rising_entropy**: Entropy (S) increasing over time, indicating growing uncertainty or exploration.
-- **falling_energy**: Energy (E) declining, signalling withdrawal or depletion.
-- **basin_transition_down**: Sharp downward shift in the energy basin (E and I drop across a threshold).
-- **basin_transition_up**: Sharp upward shift in the energy basin (E and I rise across a threshold).
-- **entropy_spike_recovery**: Sudden entropy (S) spike followed by recovery toward baseline.
-- **drift_dissonance**: Sustained dissonance with drifting EISV values and no clear attractor.
-- **void_rising**: V increasing as energy exceeds integrity (E > I); presence fading.
-- **convergence**: Multiple EISV dimensions converging toward a shared equilibrium.
+**Total real-only:** 20,655 windows.
 
-### Shape Classification Note
+Synthetic augmentation contributes 11,526 windows distributed across the eight underrepresented shapes (and is the sole source of `drift_dissonance` examples). Augmentation breakdown is in the Parquet itself; filter on `provenance` to recover either subset.
 
-Shape labels in this dataset were generated from **20-step trajectory windows**.
-If you reclassify using shorter windows, expect significant label disagreement:
+### Window-length sensitivity
 
-| Window Size | Label Match |
-|-------------|-------------|
+Shape labels in this artefact are computed from **20-step windows**. Reclassifying the same EISV time-series with shorter windows produces predictable label disagreement:
+
+| Window size | Label match vs. 20-step |
+|---|---|
 | 4-step | 65% |
 | 8-step | 77% |
 | 10-step | 81% |
 | 15-step | 91% |
 | 20-step | 100% |
 
-Most mismatches (5,138 cases) are `settled_presence` → `convergence`.
-A 4-step window only sees the tail end of a settling trajectory, which looks
-like convergence. The full 20-step arc is needed to confirm the system has
-actually settled. If training on this dataset, use at least 10-15 steps for
-reliable shape classification.
+The dominant disagreement (~5,138 windows in the 4-step case) is `settled_presence` → `convergence`: a 4-step window only sees the tail of a settling trajectory, which looks indistinguishable from convergence. Use ≥ 10–15 steps for reliable shape labels.

-- **Total records**: 32181
+## Reproducing paper claims
 
-### Shape Distribution
+The neuro-AI paper (Wang 2026b §5.1) cites the real-Lumen shape distribution as the baseline against which Type 1 (repeated-hits) failure is measured. **Numbers in Wang 2026b §5.1 reflect an earlier dataset cut** (21,449 windows; `entropy_spike_recovery` 4.91%, `settled_presence` 47.19%). The current Hub artefact has 20,655 real windows with the distribution in the table above. The qualitative claim — that `entropy_spike_recovery` is rare relative to `settled_presence` and so the ratio of the two is a Type 1 indicator — is unchanged at this revision; the exact numbers should be re-cited from this card or the Wang 2026b §5.1 numbers updated to match.
 
-| Shape | Count |
-|-------|-------|
-| basin_transition_down | 2000 |
-| basin_transition_up | 2000 |
-| convergence | 8089 |
-| drift_dissonance | 2000 |
-| entropy_spike_recovery | 2000 |
-| falling_energy | 2000 |
-| rising_entropy | 2000 |
-| settled_presence | 10092 |
-| void_rising | 2000 |
+The 28.9% basin-flip rate (Wang 2026a §11.6, Wang 2026b §3.4) is computed on a **separate** dataset of state vectors (not trajectory windows) and is published as [`hikewa/unitares-verdict-counterfactual-v6.8`](https://huggingface.co/datasets/hikewa/unitares-verdict-counterfactual-v6.8). Do not attempt to reproduce the 28.9% number from this dataset — they are different artefacts.

+## Considerations for use
+
+### Intended uses
 
-## Models Trained on This Dataset
+- Benchmarking trajectory-shape classifiers on real embodied-AI dynamics.
+- Training and evaluating dynamics-emergent expression generators (the original EISV-Lumen task; see [§ Companion artefacts](#companion-artefacts)).
+- Reproducing or auditing claims about Lumen's behavioural distribution in Wang 2026a / Wang 2026b.
+- Studying class-imbalanced trajectory classification under realistic skew.
 
-### Teacher (Qwen3-4B + LoRA)
+### Out-of-scope uses
 
-A Qwen3-4B model fine-tuned with LoRA (rank 16, alpha 32) on a 50/50 blend of real Lumen trajectories and synthetic data.
+- **Re-identifying or profiling humans.** Lumen has no human user model; the dataset is sensor-driven physical state plus governance metrics. There is no human PII in the windows.
+- **Cross-agent generalisation claims.** This dataset is from one Raspberry Pi 4 in one physical environment. Class-conditional results from Wang 2026a Table 5 (5 agent classes) require their own data; this dataset speaks only for the Lumen class and only for the 39-day window covered.
+- **Fine-grained temporal claims past the dataset window.** Lumen has run for 118+ days as of Wang 2026b's drafting; this dataset is a 39-day slice (2026-01-11 to 2026-02-19). Behavioural claims on Lumen's full operational lifetime require pulling fresh data.
+- **Synthetic-window analysis as evidence about Lumen.** The 11,526 synthetic windows exist to balance class distribution for downstream modelling; treating them as observations of Lumen's behaviour is a category error. Always filter on `provenance == "lumen_real"` for any empirical claim about the agent.
 
-| Metric | Synthetic Eval | Real Eval |
-|--------|---------------|-----------|
-| Mean coherence | 0.911 | **0.952** |
-| Valid rate | 100% | 100% |
-| Pattern accuracy | 26% | 30% |
+### Biases, limitations, known gaps
 
-The teacher surpasses the rule-based baseline (0.933) on real data, demonstrating that neural models can learn dynamics-emergent expression from trajectory patterns.
+- **Severe class imbalance in the real corpus.** Two shapes (`settled_presence`, `convergence`) account for 88% of real windows. Models trained without rebalancing will collapse toward the majority class. Synthetic augmentation in this artefact is one rebalancing strategy; cost-sensitive training is another.
+- **`drift_dissonance` has never been observed organically.** All `drift_dissonance` examples are synthetic. Treat shape-classifier accuracy on this label as accuracy on synthetic data, not on real Lumen behaviour.
+- **Single-agent, single-environment.** Lumen sits on a single physical Pi in a single home environment. Sensor readings reflect that environment's diurnal cycle, HVAC, occupancy, and ambient light — not a normalised lab condition. Distributional claims do not transfer to other Lumen-class agents without re-measurement.
+- **Token alignment is sparse.** Only 3.8% of real windows have aligned primitive-token expressions (`n_expressions > 0`). Models trained on the joint `(window, tokens)` task should expect to learn from the long tail; use the `tokens` column as a sparse signal, not as a dense supervision target.
+- **Sensor cadence is not strictly uniform.** Inter-state intervals are typically ~2 s but can vary with system load. The `t` field on each EISV state preserves the actual sample time; downstream models that assume uniform spacing will need to interpolate.
+- **The dataset publisher script is the source of truth for shape rules.** The informal descriptions in [§ Shape classification](#shape-classification) are a documentation aid; if rules and table disagree, the [`eisv_lumen.scripts.publish_dataset`](https://github.com/CIRWEL/eisv-lumen) script wins.
 
-### Student (Distilled RandomForest)
+### Privacy & ethics
 
-Lightweight models distilled from the teacher for edge deployment (Raspberry Pi):
+This dataset captures the internal state of an AI agent, not human behaviour. It contains no PII. Sensor readings (temperature, humidity, light) are aggregated into the EISV projection at collection time — raw sensor traces are *not* included. Researchers concerned about indirect inference about the household where Lumen runs (e.g., via diurnal temperature patterns) should note that the projection layer collapses sensor specifics into the EISV manifold before storage.
