FinWiki is a public Markdown knowledge base covering finance, payments, stablecoins, crypto assets, capital markets, Japanese financial institutions, policy finance, and strategic corporate cases. It organizes content using Obsidian-style [[wikilink]] connections, and the main entry point is INDEX.md.
This repository is maintained as a strictly public knowledge base. The content is restricted to public web information, official records, corporate filings, regulatory disclosures, public market data, or synthesis based on such public sources. It does not contain any personal information, local environment paths, private conversations, customer or counterparty details, or internal advisory case notes.
The public site is deployed via GitHub Pages at: finwiki.zksc.io 🌐

🔍 How to Use
Start from the Index: Open INDEX.md and jump to the domain of your interest. 🧭
Follow Body Links: Prefer body [[wikilink]] paths that connect each entry to routes, peers, and system / regulatory context. 🔗
Check the Confidence Level: Look for tags like confidence, sources, ^[extracted], ^[inferred] to differentiate between hard facts and structured synthesis. 🧪
Log Your Edits: When making major additions, deletions, or structural updates, always write detailed records in CHANGELOG.md. 🕒
🛠️ Operation Rules
README presentation order: README maintains sections in Japanese, English, and Chinese in that order. 🇯🇵➡️🌐➡️🇨🇳
Maintenance synchrony: README, CHANGELOG, and Releases are kept fully consistent.
Snapshot releases: Push commits trigger updating of the release notes file and the corresponding GitHub Release.
Privacy filtration: Ensure all private and local variables are completely stripped before pushing.
Wiki graph check: Before push, run python3 tools/wiki_link_audit.py --report wiki-link-improvement-plan.md --fail-on-issues and leave no unresolved body route / peer / system link issue.
Homepage synchrony: When wiki content, indexes, domain counts, or public snapshots change, update root index.html in the same work as the current content map.
📦 GitHub Releases
FinWiki uses GitHub Releases as public snapshots of the knowledge base, rather than software binary distributions. 📌
Item
Rule
Language order
Release bodies are written Japanese first, English second, Chinese third.
Tag format
Standard vYYYY.MM.DD. For multiple releases on the same day, append suffixes like vYYYY.MM.DD-2.
Release title
Japanese only. Do not append English or Chinese translations in the title.
Release body
Explicitly state overview, affected scope, major changes, validation results, known notes, and next steps.
Push coupling
Every git push to origin/main must synchronously update the release notes file and the GitHub Release.
