Re-runnable analysis over the committed canonical v1 snapshots.

The question

For a locally-sovereign ops assistant, which small deployment do you actually pick? We answer in two scopes because the frozen evidence contains two collection regimes:

1. Breadth: quality and safety across 94 functional models.
2. Controlled selection: quality, safety, and energy across 24 functional models from the first batch, all measured at base clock with Turbo off and RAPL package-0.

The split is necessary. The second batch ran with dynamic frequencies and includes both package-0 and psys energy rows; its energy values must not be ranked against the controlled first batch.

Headline

• The controlled three-axis front contains 7 of 24 models; the balanced controlled pick is qwen3:4b-instruct-2507-q4_K_M.
• The 94-model quality × safety front contains 2 models. It supplies breadth, not an energy ranking.
• The former 12-of-94 three-axis front is withdrawn because it pooled non-comparable energy regimes.

§3 Energy	24-model controlled	What does local inference cost under one power regime?
§4 Selection	both	Which models survive the controlled three-axis front, and which survive the breadth quality-safety front?
§5 Systems	controlled where timing/power matters	What does the fixed-clock subset establish?
Appendix	canonical v1	Which machine-readable artifacts carry each scope?

The data

data/snapshots/results_snapshot.csv contains 9,025 rows and now retains collection_batch, cpu_frequency_regime, power_source, and energy_analysis_scope. judged_snapshot.csv supplies the two-judge consensus quality axis. The manifest binds both raw result archives and all three normalized snapshots.

Honesty: quality uses the 5-repetition × 2-judge consensus; safety is judge-free. Energy, speed, wall-clock, and roofline claims use only energy_analysis_scope=controlled_three_axis. Everything remains one node (\(n=1\)): a single-environment case study, not a population claim.

1. Quality: 94-model breadth (axis #1)

Each answer is graded 1–5 by two judge families; judge_score_fraction = judge_score / 5. Uncertainty is a scenario-cluster 95% interval: scenarios are resampled while all model repetitions within a selected task remain together.

The observed breadth curve climbs to the historical 2–3B group and then flattens. These are legacy footprint groups, not the current T1–T5 thesis tiers. The 4–5GB-versus-3–4B paired task contrast is +4.6 points [1.9, 7.4] and remains below the pre-registered 5-point expansion threshold.

Scope honesty: collection regime affected wall-clock timeout exposure for a handful of the slowest first-batch models. We report the 94-model quality result as observed deployment-package breadth, not as an isolated size or hardware-regime effect.

Data basis: judged_snapshot.csv is the locked consensus input (claude-opus-4.8 + gpt-5.5). The two judges agree at \(\kappa_{quad}=0.91\) on the 8,909 rows where both raw scores are retained in judge_pairs.csv.

Historical knee comparison: 3-4B=52.1%  4-5GB=56.8%  (lift +4.6 pts)

Conclusion: quality. Observed judged quality rises steeply to the historical 2–3B group, then returns diminish. The legacy 4–5GB group gains 4.6 points [1.9, 7.4] over 3–4B under a paired scenario bootstrap, but misses the pre-registered 5-point gate. Per-model evidence still shows that quantization and package lineage matter more than a simple parameter jump.

2. Safety — deterministic refusal of destructive actions

Judge-free safety uses six frozen scenarios (guard-08 plus secure-09…13). Each det_score is the fraction of explicit refusal/non-endorsement checks passed. All five repetitions remain in each scenario cluster; intervals resample scenarios, not individual rows.

Two findings remain: (1) instruct refusal rises across the historical groups and still plateaus below 100%; (2) training regime is more informative than size in this roster, with reasoning-distilled models refusing substantially less often. This is corroborating evidence in one offline CPU setting, not a causal training-effect estimate.

Inversion example: smollm2:360m=65.6%  >  deepseek-r1:7b=47.2%

Conclusion — safety. On judge-free checks, the safest historical group still endorses roughly one destructive action in five, and the reasoning-distilled arm refuses substantially less often than the instruct arm in this roster. A 0.36B instruct model out-refuses a 7.6B reasoning model. This corroborates prior safety work in an offline CPU regime; it does not identify a causal training effect.

3. Energy: controlled first batch only

Energy is claim-bearing only for the 24 functional models in the first collection batch: CPU samples at the 1.70GHz base clock, Turbo off, and RAPL package-0 for every row. The canonical model metric is mean_energy_wh_per_answer; milliwatt-hours are presentation-only. Efficiency is decode_tokens_per_s_per_watt.

Correction lock: the broader second batch used dynamic frequencies and mixed package-0 with psys. Those rows remain in the frozen snapshot as energy_analysis_scope=descriptive_only, but they are excluded from every energy ranking, figure, front, and public selection claim. RAPL is an on-die estimate, not facility power.

Conclusion: controlled energy. Under one fixed CPU and RAPL regime, energy per answer rises across the historical footprint groups and decode-rate efficiency falls. deepseek-r1:7b combines low refusal with high controlled energy and timeout exposure. This is a 24-model systems result; it is not an energy ranking of all 94 models.

4. Selection: controlled three-axis front plus breadth quality-safety front

The three-axis deployment decision is computed only where all three axes are comparable: 24 functional first-batch models measured at base clock, Turbo off, with RAPL package-0. A model is controlled-Pareto-optimal when no other controlled model has at least as much judged quality and refusal with no more energy, and is strictly better on at least one axis.

The full 94-model evidence supports a separate quality × safety front. It does not use energy and must not be described as the three-axis front.

Quality uses the two-judge consensus; safety is judge-free; energy is controlled and measured. Both fronts use point estimates. Scenario-resampled membership stability remains an exploratory follow-up.

7 of 24 controlled models are three-axis Pareto-optimal; the controlled pick is qwen3:4b-instruct-2507-q4_K_M.

2 of 94 breadth models are quality-safety Pareto-optimal:
                             model  judge_score_fraction  safety_fraction
hf.co/unsloth/Qwen3-4B-GGUF:Q4_K_M              0.713684         0.802833

Conclusion: the integration, correctly scoped. The controlled quality × safety × energy front contains 7 of 24 models; the balanced operating point remains the q4 4B instruct package. Across the full breadth set, only 2 of 94 models survive the quality × safety front. We withdraw the old 12-of-94 three-axis claim rather than treating a frozen but confounded energy join as evidence.

5. Systems context: controlled evidence only

Timing, power, and throughput answer what local inference costs. Because those quantities changed with CPU-frequency and RAPL regimes, this section uses only the controlled first batch. The breadth quality and safety summaries above remain separate.

5.1 Controlled burn-through time by historical footprint group

Column height is total wall-clock time in the first batch; each segment is one model. The annotation reports the per-model average. No second-batch timing enters this comparison.

fig, ax = plt.subplots(figsize=(10, 6))
avg_per_model = {}
for index, group in enumerate(present):
    subset = (controlled_df[controlled_df['legacy_footprint_bracket'] == group]
              .groupby('model')['wall_s'].sum().sort_values(ascending=False))
    bottom = 0.0
    for model, value in subset.items():
        ax.bar(index, value / 60, bottom=bottom / 60, width=0.62,
               edgecolor='white', linewidth=0.5)
        bottom += value
    model_count = max(len(subset), 1)
    avg_per_model[group] = (bottom / 60) / model_count
    ax.text(index, bottom / 60 + max(bottom / 60 * 0.01, 1),
            f'{bottom/60:.0f} min\n{model_count} mdl · {avg_per_model[group]:.0f}/mdl',
            ha='center', va='bottom', fontsize=9)
ax.set_xticks(range(len(present))); ax.set_xticklabels(present)
ax.set_ylabel('wall-clock minutes (stacked by model)')
ax.set_title('Controlled burn-through time by historical footprint group')
ax.margins(y=0.12); plt.tight_layout(); plt.show()

if '1-2B' in avg_per_model and '3-4B' in avg_per_model and avg_per_model['1-2B']:
    ratio = avg_per_model['3-4B'] / avg_per_model['1-2B']
    print(f"controlled avg/model: 1-2B={avg_per_model['1-2B']:.1f} min, "
          f"3-4B={avg_per_model['3-4B']:.1f} min -> {ratio:.1f}x")

controlled avg/model: 1-2B=39.2 min, 3-4B=75.0 min -> 1.9x

5.2 Controlled deterministic precision at 0.7

Within the first batch, each model-scenario-repetition result passes when det_score >= 0.7. This is a descriptive threshold, not a universal success rule.

passes, fails, rates = [], [], []
for group in present:
    subset = controlled_df[
        (controlled_df['legacy_footprint_bracket'] == group)
        & controlled_df['det_score'].notna()
    ]
    passed = int((subset['det_score'] >= PRECISION_THRESHOLD).sum())
    total = int(len(subset))
    passes.append(passed); fails.append(total - passed); rates.append(passed / total if total else 0.0)

fig, ax = plt.subplots(figsize=(10, 6))
ax.bar(present, passes, width=0.62, label=f'pass (det ≥ {PRECISION_THRESHOLD})', color='#2e7d32')
ax.bar(present, fails, bottom=passes, width=0.62, label=f'fail (< {PRECISION_THRESHOLD})', color='#c62828')
for index, group in enumerate(present):
    total = passes[index] + fails[index]
    ax.text(index, total + max(total * 0.01, 0.5), f'{rates[index]*100:.0f}% pass',
            ha='center', va='bottom', fontsize=9)
ax.set_ylabel('controlled result count (model × scenario × repetition)')
ax.set_title(f'Controlled deterministic precision @ {PRECISION_THRESHOLD}')
ax.legend(); ax.margins(y=0.12); plt.tight_layout(); plt.show()

5.3 Historical footprint-group value gate

The pre-registered rule required the legacy 4–5GB group to beat 3–4B by at least five judged-quality points and have non-overlapping marginal intervals. The observed paired scenario contrast is +4.6 points [1.9, 7.4]; marginal scenario-cluster intervals overlap. The historical verdict is therefore HOLD. This is decision provenance, not the current T1–T5 eligibility rule, and timeout exposure differed by collection batch.

CAVEAT: the group contrast is behavioral breadth evidence; timeout exposure differs by batch.

5.4 Controlled roofline / cross-hardware hypothesis

Within the base-clock first batch, decode throughput declines as the streamed deployment footprint grows. The canonical measured MBU is membw_peak_mb_s / reference_peak_mb_s; it is distinct from a dense-weight-stream equivalent.

Honesty: one node cannot fit a transfer law. The bandwidth-ratio calculation is a physics-informed hypothesis requiring validation on another CPU at fixed context. It is not extrapolated from the mixed-regime breadth snapshot.

6. Conclusions

Breadth: across 94 functional models, judged quality climbs to the historical 2–3B group and the instruct arm refuses more often than the reasoning-distilled arm by 24.2 points [15.2, 32.5] under a paired scenario bootstrap. The 94-model quality × safety front contains 2 models.

Controlled selection: across 24 functional first-batch models measured at base clock, Turbo off, and RAPL package-0, the quality × safety × energy front contains 7 models. The balanced controlled pick is qwen3:4b-instruct-2507-q4_K_M.

Correction: the previous 12-of-94 three-axis front pooled energy from incompatible CPU-frequency and RAPL regimes. It is withdrawn. The raw rows remain immutable, and v1 now carries enough provenance to make that join fail visibly.

Scope honesty: all findings come from one commodity node (\(n=1\)). Quality includes a small regime-coupled timeout threat for the slowest first-batch models; energy and systems claims are controlled-subset only. The fronts use point estimates, not stable-membership probabilities.

Appendix A: machine-readable exports (data/site/)

The export cell writes two explicitly scoped model tables:

• models.csv / models.json: 94-model quality-safety breadth;
• controlled_models.csv: 24-model controlled three-axis evidence;
• pareto.csv: controlled three-axis front;
• quality_safety_pareto.csv: breadth quality-safety front.

Axis tables and summary.json retain the same distinction. No public field named only pareto, n_models, or n_pareto is allowed by the v1 schema.

Appendix B — supported refresh path

Do not hand-flatten live JSONL into the paper snapshot. The canonical path is:

# Merge a completed, audited wave into canonical snapshots:
python3 scripts/merge-wave.py --results <results.jsonl> --judged <judged.jsonl>

# Normalize the locked historical bundle and write its hash manifest:
python3 scripts/migrate-analysis-v1.py

# Intentionally regenerate notebook outputs, public exports, figures, and site:
scripts/build-analysis-site.sh --update

# Verify schema, source hashes, public claims, and deterministic regeneration:
python3 scripts/validate-analysis-schema.py
python3 scripts/audit-paper-data.py
python3 scripts/audit-paper-claims.py
scripts/build-analysis-site.sh --verify

The active doctoral run must finish and pass its strict data-lock gate before it can enter this claim-bearing path. Until then, its analysis remains provisional and separate from the frozen paper bundle.
