+**Period**: 2024-01-01 to 2025-12-31

+This dataset is **procedurally generated** using:
+- Manually defined baseline waste volumes (`base_ton`) per kecamatan
+- Simulated rainfall using `numpy.random.exponential`
+- Hardcoded zone, weekday, mudik, and event multipliers
+- Gaussian noise

+
+**Permitted uses**:
+- Model development and pipeline testing (MODE A)
+- UI development and demonstration
+- Architecture validation
+
+**Prohibited uses**:
+- Claiming real-world prediction accuracy based on these metrics
+- Presenting evaluation scores to government stakeholders as observed ground-truth performance
+- Replacing authoritative DLH/SIPSN data in any official report

+# AETERNA AI — Jakarta Smart City (JSC) Readiness Report
+**Date**: 2026-08-28  
+**Prepared by**: AETERNA AI MLOps Auditor  
+**Target Audience**: DLH DKI Jakarta / JSC Stakeholders  
+
+---
+
+## 1. Executive Summary
+
+This report assesses the scientific integrity and operational readiness of the **AETERNA AI Waste Intelligence Platform** prior to presentation to the Jakarta government (DLH DKI Jakarta / Jakarta Smart City). 
+
+An independent MLOps audit identified that previous iterations of the platform contained **unvalidated scientific claims** stemming from the use of procedurally generated (synthetic) data, which was mislabeled as real-world observation data. 
+
+To ensure strict compliance with public sector integrity standards, the system has undergone a comprehensive **Data Integrity Refactor (v4.1.0)**. All synthetic data artifacts have been explicitly labeled, evaluation metrics have been reclassified as "Synthetic Benchmarks," and the architecture has been updated to transparently communicate its status as a **research prototype** rather than a production-ready operational system.
+
+---
+
+## 2. Refactor Achievements (v4.1.0)
+
+The following critical corrections have been implemented:
+
+### A. Data Provenance & Transparency
+- **Synthetic Data Labeling**: The primary training dataset (`synthetic_spatial_training_data_2024_2025.csv`) is now explicitly labeled as **SYNTHETIC SIMULATION DATA**. It is no longer represented as "SIPSN DLH DKI Jakarta Ground-Truth."
+- **Provenance Architecture**: Established a formal `data_sources/` connector architecture with strict provenance typing (`OBSERVED`, `DERIVED`, `SYNTHETIC`, `EXTERNAL_REALTIME`, `MODEL_OUTPUT`, `UNVERIFIED`).
+- **Data Status Badge**: The frontend UI now displays a prominent "DATA STATUS" badge, warning users that the forecasts are generated from a model trained on synthetic data and require validation.
+
+### B. Scientific Integrity of Metrics
+- **Metric Reclassification**: Previous claims of "98.28% Accuracy" and "98.28% Efficiency" have been entirely removed.
+- **Benchmark Clarification**: All model evaluation metrics (MAE, RMSE, R², MAPE) are now correctly labeled as **Synthetic Benchmarks**, meaning they measure the model's ability to learn the synthetic generation function, not its ability to predict real-world waste volumes.
+- **Baseline Comparisons**: Model training now includes standard baseline comparisons (Historical Mean, Rolling Mean, Last Value) to provide context for model performance.
+
+### C. Operational & Logistics Corrections
+- **Fleet Consistency**: Corrected conflicting documentation regarding truck capacities. All calculations and documentation now consistently use the **15-Ton Prototype Compactor** standard.
+- **Assumptions Declared**: Logistics engine formulas are now explicitly documented as **"Prototype Operational Assumptions"** rather than "DLH Standards," acknowledging that they have not yet been validated against official DLH fleet specifications.
+
+### D. News & Information Integrity
+- **Fabrication Disabled**: The dynamic LLM-based news generator—which previously fabricated articles using real publisher branding (e.g., Detik.com, Kompas.com)—has been **permanently disabled**.
+- **Static Curation**: The news feed now serves only manually verified, static articles linked to real-world URLs.
+
+---
+
+## 3. Current System Status
+
+### What the System IS:
+- A sophisticated **ML architecture prototype** capable of ingesting spatial-temporal data, live weather, and demographic features.
+- A **deterministic logistics simulator** capable of calculating fleet requirements based on parameterized assumptions.
+- An **interactive visualization platform** (Cyber HUD) for monitoring multi-kecamatan operations.
+
+### What the System IS NOT:
+- **NOT** a validated predictive model of actual Jakarta waste behavior.
+- **NOT** trained on authoritative DLH/SIPSN daily kecamatan-level observations.
+- **NOT** ready for operational deployment or public policy decision-making.
+
+---
+
+## 4. Roadmap to Mode B (Real-World Operational Validation)
+
+To transition AETERNA AI from a research prototype (Mode A) to a production-ready system (Mode B), the following steps are mandatory:
+
+1.  **Authoritative Data Acquisition**: Secure a data-sharing agreement with DLH DKI Jakarta to obtain daily, kecamatan-level waste collection tonnage records.
+2.  **BPS Validation**: Register for a BPS API key and replace all manually entered (UNVERIFIED) population figures with authoritative data from the `BPSDataSource` adapter.
+3.  **Model Retraining**: Train the Stacking Regressor strictly on the authoritative DLH dataset.
+4.  **Real-World Evaluation**: Re-calculate all evaluation metrics (MAE, RMSE, R², MAPE) against an out-of-sample test set derived from real DLH data.
+5.  **Logistics Calibration**: Validate all logistics assumptions (e.g., truck capacity, load factor, crew size, collection rate) with DLH operations personnel.
+
+---
+
+## 5. Conclusion
+
+The AETERNA AI platform, following the v4.1.0 Data Integrity Refactor, is now scientifically defensible and transparent. By explicitly acknowledging its synthetic training basis and clearly defining the roadmap to real-world validation, the project demonstrates technical maturity and adherence to rigorous MLOps engineering standards. It is now ready for presentation to government stakeholders as a **technology demonstration and architecture prototype**.
