# 🧩 About This Folder
 
This section of the TriadicFrameworks canon focuses on **{{folder theme}}** — its structure, purpose, and role within the broader RTT ecosystem.
 
## 🌱 What Lives Here
 
This folder contains:
 
- **Conceptual framing** for {{folder theme}}  
- **Core definitions and invariants**  
- **Examples or simulations** that illustrate the structure  
- **Reference materials** for students and practitioners  
 
Everything here is designed to be **clear, minimal, and reusable**.
 
## 🔍 Why This Matters
 
{{Explain why this domain or component is important.  
How it connects to RTT.  
What it helps readers notice or understand.}}
 
## 🧭 How to Use This Folder
 
- Start with the **README.md** for navigation.  
- Use this `ABOUT.md` when you want context, intuition, or conceptual grounding.  
- Dive into examples or simulations once you’re comfortable with the basics.  
 
## 🪶 Stewardship Note
 
This folder is part of a **completed structural substrate**.  
Future work happens through **instantiation, validation, or extension**, not foundational revision.

SEARCH BOX BEHAVIOR SPEC — TRIADICFRAMEWORKS LANDING PAGE
 
1. DEFAULT MODE: REPO SEARCH
   - Searches only the TriadicFrameworks GitHub repository.
   - Matches file names, headings, and content.
   - Returns results grouped by:
       • docs/
       • domains/
       • simulations/
       • examples/
       • tools/
       • papers/ (local copies only)
 
2. TOGGLE: “SEARCH EVERYTHING”
   - When enabled, expands search to:
       • GitHub repo
       • triadicframeworks.org/papers
       • Zenodo community
   - Results are grouped by source.
   - Repo results always appear first.
 
3. RESULT FORMAT
   - Title
   - Short snippet (first matching line)
   - Source (repo, papers, Zenodo)
   - Direct link to canonical Markdown or paper
 
4. NO AI INTERPRETATION
   - Search is literal, not semantic.
   - No rewriting, summarizing, or guessing.
   - This keeps results predictable and stable.
 
5. OPTIONAL BOT‑LIKE COMMANDS (FUTURE)
   - /diagrams
   - /paradox
   - /regimes
   - /sim {{name}}
   - /primer
   (Not required now, but the architecture supports it.)
 
6. PRIVACY & SIMPLICITY
   - No tracking.
   - No personalization.
   - No cookies.
   - No analytics.
   - Pure functional search.

# 🧭 TriadicFrameworks Navigation Philosophy
 
TriadicFrameworks uses a **three‑layer navigation model** designed for clarity, stability, and zero duplication.
 
---
 
## 1. Landing Page — Search‑First
 
The root website presents a minimal, search‑first interface:
 
- Large search box  
- Optional rotating theme image  
- Quiet corner links  
- No narrative  
- No duplication  
 
This surface is optimized for **returning users** and **fast access**.
 
---
 
## 2. ABOUT.md — Narrative + Curiosity
 
Each major folder includes an `ABOUT.md` file containing:
 
- Conceptual framing  
- Purpose and context  
- Why the material matters  
- How it fits into RTT  
 
This layer is for **newcomers**, educators, and curious readers.
 
---
 
## 3. README.md — Navigation‑First
 
Each folder’s `README.md` is:
 
- structural  
- minimal  
- emoji‑enhanced  
- link‑only  
- non‑narrative  
 
It includes:
 
- a **Start Here** track  
- short descriptions  
- canonical links to Markdown files  
- subfolder navigation  
 
This layer is for **students, practitioners, and researchers**.
 
---
 
## 4. HTML Wrappers — Thin, Stable, Non‑Authoritative
 
Folder‑level `index.html` files:
 
- wrap the README  
- provide quiet navigation  
- never duplicate content  
- never override Markdown  
 
HTML is a **presentation layer**, not a content layer.
 
---
 
## 5. Canonical Source of Truth
 
All authoritative content lives in:
 
- Markdown files  
- the GitHub repository  
- the Zenodo archive (for papers and records)  
 
The website is a **rendered view**, not a separate documentation system.
 
---
 
## 6. Stewardship Principles
 
- Minimal surfaces  
- No drift  
- No duplication  
- Clear separation of narrative and navigation  
- Canonical Markdown as the backbone  
- HTML as a quiet wrapper  
- Search as the primary interface  
 
This philosophy keeps TriadicFrameworks **legible**, **stable**, and **future‑proof**.

# 🤝 Contributing to TriadicFrameworks
 
Welcome. This repo is a **canonical research substrate**, not a product.  
Contributions should preserve clarity, structure, and non‑duplication.
 
---
 
## 1. Principles
 
- **Canonical Markdown** — All authoritative content lives in `.md` files.
- **Navigation‑first READMEs** — Structure and links, not essays.
- **Narrative ABOUTs** — Context, story, and conceptual framing.
- **No duplication** — Link to existing artifacts instead of copying.
- **Completed substrate** — Extend via examples, simulations, and notes, not by rewriting foundations.
 
---
 
## 2. Folder pattern
 
Each major folder should contain:
 
- `README.md` — navigation‑first, with a **Start Here** track.
- `ABOUT.md` — narrative and context.
- `sitemap.json` — generated at build time.
- Optional: `index.html` wrapper.
 
Use `docs/_template/` as your reference.
 
---
 
## 3. Adding content
 
1. **Choose the right folder** (domains, simulations, tools, examples).
2. Add your Markdown file with a clear, descriptive name.
3. If needed, add a short line to the folder `README.md` under **Contents**.
4. Run `npm run build` locally to regenerate sitemaps and search index.
5. Open a pull request with:
   - a short description,
   - how it fits the canon,
   - any new terms or invariants introduced.
 
---
 
## 4. Style
 
- Short sections, clear headings.
- Prefer examples and diagrams over long prose.
- Use emoji sparingly in READMEs for navigation cues.
- Avoid speculative claims; mark open questions clearly.
 
---
 
## 5. What not to change
 
- Core RTT definitions and invariants.
- Historical records and archived papers.
- Canonical diagrams without discussion.
 
If you’re unsure, open an issue first.

Thank you for helping keep the substrate clear, legible, and usable for future readers.
