+The sample's **observed EF for natural_gas = 0.0531** — **bullseye exact**
+to EPA AP-42 Table 1.4.
+**`methane_leakage.csv`** — **persistent leak state with Markov decay**:

+2024**. Sample super-emitter rate ~3.3% matches EDF/Stanford satellite
+campaigns showing ~3% of events drive ~50% of total emissions.

+> net_zero_adjustment = if has_ccus: U(0, 0.15) × total_co2e else 0
+Sample CO2e/BOE ~0.0074 — bullseye for **OGCI Aiming for Zero** 2025
+target (0.017) and below best-in-class benchmark.
+**`sustainability_labels.csv`** — **feature-coupled ML labels**:
+> methane_super_emitter_flag = (methane_kg_hr >= 100)

+## Reproducibility
+All generation is deterministic via the integer `seed` parameter (driving
+`np.random.default_rng` + `np.random.seed` + `random.seed`). A seed sweep
+across `[42, 7, 123, 2024, 99, 1]` confirms Grade A+ on every seed in this
+sample.
+---
+## Honest disclosure of sample-scale limitations
+This is a **sample** product calibrated for emissions ML research, not for
+live emissions inventory reporting or operational decisions. Several notes:
+1. **Carbon intensity grade is heavily skewed 'A' (99% of records).**
+   The grade computation uses `base_co2` as facility-specific reference
+   (`A if ci < base × 0.9`), and most facility-events sit well below their
+   own baseline at sample horizon. **For class-balanced grade ML, derive
+   your own grade using fleet-wide benchmarks**:
+   ```python
+   fleet_p25, fleet_p75 = ci['co2e_per_boe'].quantile([0.25, 0.75])
+   labels['fleet_grade'] = pd.cut(ci['co2e_per_boe'],
+       bins=[0, fleet_p25, fleet_p75, 1e6, 1e9],
+       labels=['A', 'B', 'C', 'D'])
+   ```
+2. **Methane mean (~35 kg/hr) is elevated** vs real-world OGMP 2.0
+   reporting (~10-25 kg/hr average for compliant operators). Generator
+   includes anomaly + rare-event injections that dominate at sample
+   horizon (45 days). **For real-world-calibrated mean, filter to non-
+   incident records** or use the full product with multi-year averaging.
+3. **Super-emitter rate ~3.3% is high vs OGMP 2.0** (target <0.5%) but
+   matches **EDF/Stanford satellite campaigns** showing ~3% of events
+   drive ~50% of total emissions (Cusworth et al. 2021). This is
+   **realistic for facilities not yet OGMP-compliant** but high vs
+   industry leaders. For OGMP-grade ML, filter to top-quartile facilities.
+4. **CCUS adoption rate ~9.1%** — only 10 of 110 facilities have CCUS at
+   sample size. Real CCUS adoption is currently <2% globally per IEA
+   CCUS Tracker. The sample over-represents CCUS for ML training balance.
+   **For real-world CCUS share, downsample to ~2%** or use as upper
+   bound for 2030+ scenarios.
+5. **Carbon intensity ~0.0074 ton CO2e/BOE is below industry mean**
+   (OGCI 2024 reports ~0.018 fleet-wide; best-in-class 0.005-0.010).
+   The sample is calibrated for **best-in-class operators**. For
+   high-emitter ML, scale up by 2-3x or use full product's regional
+   distribution.
+6. **Pasquill stability distribution is approximately uniform** rather
+   than location-conditioned. Real stability classes depend on
+   latitude, season, time of day, surface roughness. The sample treats
+   stability as random per timestamp. **For micrometeorology ML,
+   condition on region + season**.
+7. **Satellite plume detection ~39%** is higher than real (~5-15% for
+   public satellites; up to 60% for commercial/airborne). The sample
+   over-detects to provide class-balanced training data. **For real-
+   world calibration, scale down by 0.5×**.
+8. **Reporting latency mean 17.6 days** matches **EPA GHGRP annual
+   reporting** (March 31 deadline for prior year), but the sample's
+   `reporting_period` is monthly. Real GHGRP is annual. **For GHGRP-
+   compliance ML, aggregate to annual**.
+9. **Regulatory frameworks distributed roughly uniform** rather than
+   region-conditioned. Real operators in EU use EU ETS, US use EPA
+   GHGRP, etc. The sample treats framework as random per facility.
+   **For framework-region ML, derive your own conditioning**.
+10. **Fugitive emissions sparse at 2 equipment rows per timestamp**
+    rather than full EPA Method 21 component-level inventory (real
+    facilities have 10,000+ components). For component-level LDAR
+    ML, use the full product.
