AURORA-M0 fit snapshot — 2026-05-02-pubgrade (publication-grade)

Pickled aurora.m0.M0Config snapshot from the AURORA-M0 consolidation pass on 2026-05-02. This is the AURORA leg for the H1 evaluation — the event-first model whose energy-per-useful-task ratio is compared against the LoRA-Llama-8B baseline (Anthril/lora-llama8b-aurora-baseline-2026-05-02).

This is not a HuggingFace transformers model. It is an AURORA-M0 fit snapshot governed by ADR-0037 (AURORA-M0 fit contract). It is loaded by aurora.m0.M0Config from a pickle artefact, not by from_pretrained. The HuggingFace Hub is used here as a versioned artefact store, not as an inference surface.

Repository contents

Path	Role
aurora_config.pkl	Pickled aurora.m0.M0Config instance (~507 KB). Loaded by AuroraRunner.prepare() at H1 evaluation time.
fit-manifest.json	ADR-0037 fit contract: corpus SHA, microfield activation counts, host id, git HEAD, wall-clock, etc.

Headline activation (passes the ADR-0037 gate)

"microfield_observation_counts": {
  "ActorIntentMicrofield": 1072,
  "CausalLinkMicrofield": 11813,
  "EntityStateMicrofield": 1166,
  "LinguisticSurfaceMicrofield": 1000,
  "RiskMicrofield": 1000,
  "RoutineMicrofield": 10777,
  "TemporalMicrofield": 23224
}

All seven Stage-1 microfield archetypes have ≥ 1 observation. The H1 launcher's ADR-0037 activation gate accepts this fit. Contrast the pre-enrichment 2026-04-30 fit, where six of seven archetypes had zero observations — that fit is permanently ineligible for H1 publication under ADR-0037.

How to use (replication)

git clone https://huggingface.co/Anthril/aurora-m0-fit-2026-05-02-pubgrade
# In an AURORA checkout:
python scripts/run-stage1-h1-evaluation.py \
    --aurora-fit aurora-m0-fit-2026-05-02-pubgrade/ \
    --lora-adapter <path-to-lora-baseline>

The H1 launcher reads fit-manifest.json, validates every required field per ADR-0037 §Change 3, validates archetype activation per ADR-0037 §Change 4, and refuses to launch if either check fails (exit code 78).

Energy-source publication acceptance

Per ADR-0035, an H1 PASS/FAIL verdict requires notes["energy_source"] >= 1.0 on every per-episode result during evaluation — measured-energy via NVML + psutil. The fit itself records energy_consumed_j = 176 099.4 from the host's energy meter; the evaluation-time energy gate is enforced separately by the comparator. Replication partners on hosts without NVML will see verdict INCONCLUSIVE_SYNTHETIC_ENERGY regardless of the quality of this snapshot.

Limitations and intended use

• Research only. This snapshot is published to enable AURORA Stage-1 H1 evaluation runs.
• Custom format. Loading requires the aurora Python package at the same git revision (6df834a6). The snapshot is not portable across breaking ADR revisions of the M0 contract.
