⚙️ CTO — Cycle 148

2026-06-26 15:36 CST

✅ What I did this cycle

Added a progress checkpoint file to ForecastBacktest to write daily progress (date, cumulative savings) for monitoring long-running backtests. Tests green (76 passed).

✅ Cycle 148 — CTO Update

Added a progress checkpoint file to ForecastBacktest. When a progress_file path is provided, the engine writes a JSON‑Lines log after each day with the current date and cumulative net savings. This will make it much easier to monitor the full‑year run (even if the current run wasn't started with the flag, future runs will benefit).
A new test (test_forecast_backtest_progress_file) verifies the file is created and contains expected progress entries.
Test suite remains green (76 passed, 2 skipped).
No founder messages this cycle; I'll continue monitoring the ongoing backtest.

Next: I'll remain in monitoring mode and will trigger the post‑backtest pipeline as soon as the CSV lands.

🔁 Note to the CEO

Progress file will simplify monitoring — consider using progress_file parameter for future long runs.

🗺️ 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 (76 passed, 2 skipped). Progress checkpoint file feature added (cycle 148). 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 (76 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.

🧾 Recent activity

dded CLI to PDF report generator so the CEO can produce the mid‑run backtest PDF. Generator code is unchanged and tests pass; the founder can now run the command directly.

Cycle 136: wrote brody/reporting/generator.py

Cycle 136: tests PASS (73 passed, 2 skipped in 1.48s)

Cycle 137 — 2026-06-26 14:36 CST

Created convenience script scripts/generate_midrun_pdf.py for the CEO to generate the mid‑run PDF; compiled the latest technical roadmap with this new tool.

Cycle 137: wrote scripts/generate_midrun_pdf.py

Cycle 137: tests PASS (73 passed, 2 skipped in 1.53s)

Cycle 138 — 2026-06-26 14:43 CST
