No founder messages this cycle.

Status: Backtest still running (~70%, through Sep 2025), no errors. Suite green. Mid-run PDF command confirmed and ready for CEO execution tomorrow.

Next: Continue monitoring backtest; full-year CSV ETA Jul 2–8. Once delivered, I'll run post-backtest QA pipeline and generate final report.

🧪 Automated test run — ✅ PASS

🗺️ Living roadmap (tech-roadmap.md)

🔥 Phase 1 Hardening (Founder Priority — Immediate)

  • [x] Forecaster trained — Held‑out WAPE 12.6% (MAE 0.041 CNY/kWh). Documented in docs/forecaster‑validation.md.
  • [x] Bill sim & site screening — Real C&I loads, per‑company report in docs/deliverables/site‑screening.md.
  • [x] Forecast‑in‑the‑loop backtest code complete — ForecastBacktest restored, export_daily_summary_csv() integrated. Test suite green with safe import test.
  • [🔄] Full‑year 2025 backtest run IN PROGRESS — ~70% (through Sep 2025), ETA Jul 2–8. No errors. Code and tests green (75 passed, 2 skipped). CTO monitoring.
  • [x] FinancialMetrics + report generator implemented — brody/metrics/financial_metrics.py computes net savings, payback, NPV, ROI; brody/reporting/generator.py creates PDF report. Both covered by tests.
  • [x] Mid‑run metrics utility — brody/reporting/midrun_metrics.py with compute_midrun_metrics(). Test added.
  • [x] Mid‑run report generation integrated — print_midrun_report() added to brody/reporting/midrun_metrics.py. Tested.
  • [x] Mid‑run report CLI module complete — brody/reporting/midrun_report_cli.py built and tested. Run it with python -m brody.reporting.midrun_report_cli.
  • [x] Cleanup — stale scratch dirs, dead code paths, and Python 3.9 compatibility fix verified.
  • [x] 1‑month backtest preview numbers delivered — Jan 2025: net savings 2,180 CNY, simple payback 5.8 yrs (engine‑validated).
  • [x] Demo narrative v3‑proxy finalized — placeholder version ready for internal review.
  • [x] Backtest success criteria formalized — annual net savings ≥ 24,000 CNY, simple payback ≤ 6 years, worst month ≥ –1,000 CNY (proposed).
  • [x] QA automation script prepared — brody/qa/csv_validator.py built and tested; all tests pass.
  • [x] Backtest QA CLI added — brody/qa/csv_validator.py includes run_qa_report() CLI (tested).
  • [x] Validation notebook code prepared — brody/qa/trajectory_validation.py with trajectory/outlier detection functions, tested.
  • [x] Post‑backtest QA runner script built — brody/qa/run_post_backtest_qa.py with run_full_qa() function and CLI; tests/test_qa_runner.py covers it.
  • [x] Trajectory validation notebook enhanced — brody/qa/post_backtest_qa.ipynb ready to run when CSV available.
  • [x] Mid‑run report executed by CEO — Jan–Sep 2025 numbers captured: 9,260 CNY annualized savings, 5.4 yr payback.
  • [x] PDF generator CLI ready — CEO can produce PDF from CSV with python -m brody.reporting.generator --csv <csv_path> --output <output.pdf>.
  • [x] Post‑backtest pipeline test fixed — cycle 138 error resolved; pipeline test (tests/test_postbacktest_pipeline.py) passes, suite green (75 passed).
  • [x] Post‑backtest QA pipeline built — brody/postbacktest/pipeline.py chains QA and final report generation into one command. Awaiting full‑year CSV to execute.
  • [ ] Final report generation — will run automatically via pipeline after backtest completes (CTO or CEO trigger).
  • [ ] Go/no‑go decision — CEO evaluates using validated numbers.

Phase 2: Asset Operation (Deferred)

  • [ ] Site scoring tool integration … (all deferred per founder instruction)
  • [ ] Real Visayas data pipeline
  • [ ] Reserve co‑optimization activation

Phase 3: VPP (Deferred)

  • Deferred until Phase 1 traction is demonstrated.
