Changelog
Everything shipped this session, newest first.
Full English version + header language toggle.
Rebuilt the page with two complete language versions (proper English, not a translation stub) and a 中文 / English toggle top-right — instant switch, no reload, remembers the choice. Default Chinese. Both states screenshot-verified. Group notified so Dom can guide the client in English.
Deploy to Cloudflare Pages + send client the draft link.
Live at 4dmoneybox.pages.dev (noindex). Cockpit at 4dmoneybox-cockpit.pages.dev. Draft link sent to the group, verified serving real content live.
Report page (Option A) built — Mandarin-primary statistical study.
Single self-contained page: hypothesis, data & method, digit-frequency chart, per-position chi-square table, digit-sum curve, hot/cold numbers, and an honest verdict. Inline SVG charts (no external deps) → deploys straight to CF Pages. Includes a "no gambling advice / no win promise" disclaimer.
Randomness analysis engine.
Digit frequency, per-position & pooled chi-square (hand-verified against df=9 critical values), digit-sum distribution, hot/cold. Result: all 4 positions consistent with uniform; a single marginal pooled blip (digit 2, z=−3.12) shown honestly as random fluctuation, not a "finding". Verdict: draws consistent with fair randomness — no exploitable structure.
Data pipeline + dataset.
Fetch/parse from Singapore Pools' official per-draw endpoint (cross-checked against published results). 470 draws compiled (Jul 2023 → Jul 2026), 10,810 winning numbers. On-disk cache; extensible to full history.
WhatsAgent set up for the group; client confirmed Option A.
Bilingual (Mandarin-first) ack persona; intro-on-join baked into the provisioner. End client John Ling 亚胜 confirmed Option A (research report). Scope agreed.
