 ### Overview
 
-We maintain a **clean, hierarchical documentation structure** to avoid documentation sprawl. All working documents have a defined lifecycle and location.
+We use the **[Diátaxis](https://diataxis.fr/) framework** for all documentation. This prevents documentation sprawl by organizing content into four clear categories based on purpose and audience.

+### Diátaxis Framework
+
+All documentation MUST fit into one of four categories:
+
+**📚 Tutorials** (`docs/tutorials/`)
+- **Purpose:** Learning-oriented, teach by doing
+- **Audience:** Newcomers, beginners
+- **Style:** Step-by-step lessons with guaranteed outcomes
+- **Examples:** Getting Started, First Audit
+- **Question:** "Can you teach me to...?"
+
+**🔧 How-To Guides** (`docs/how-to/`)
+- **Purpose:** Task-oriented, solve problems
+- **Audience:** Users with basic knowledge
+- **Style:** Practical recipes and solutions
+- **Examples:** Deploy, Configure, Troubleshoot
+- **Question:** "How do I...?"
+
+**📖 Reference** (`docs/reference/`)
+- **Purpose:** Information-oriented, technical facts
+- **Audience:** Users looking up specific information
+- **Style:** Dry, factual, comprehensive
+- **Examples:** API docs, Config options, Protocols
+- **Question:** "What is...?"
+
+**💡 Explanation** (`docs/explanation/`)
+- **Purpose:** Understanding-oriented, clarify concepts
+- **Audience:** Users wanting deeper understanding
+- **Style:** Discussion, context, alternatives
+- **Examples:** Architecture, Design Decisions, Comparisons
+- **Question:** "Why...?"
+
+**See:** [Diátaxis documentation](https://diataxis.fr/) for detailed guidance.

 ## 📋 Document Lifecycle
 
-### 1. Working Documents (Root Level)
+### 1. Working Documents (work/ Directory)
 
-**Purpose:** Active development, session notes, status reports  
-**Location:** Project root  
-**Lifecycle:** Created → Updated → Archived  
-**Retention:** Archive after completion, delete if obsolete
+**Purpose:** Session-specific temporary files  
+**Location:** `work/` directory (.gitignore'd)  
+**Lifecycle:** Created → Used → Archived or Deleted  
+**Retention:** Archive valuable content, delete rest at session end
 
 **Examples:**
-- `TAG_MIGRATION_COMPLETE.md` → Archive when next phase starts
-- `SESSION_2025_11_04_SUMMARY.md` → Archive at session end
-- `NEXT_STEPS.md` → Update continuously, archive when complete
-- `STATUS_VISUAL.txt` → Archive immediately after session
+- `work/session-notes.md` → Session notes and progress
+- `work/status.md` → Current status report
+- `work/migration-plan.md` → Planning document
+- `work/visual-summary.txt` → ASCII art summaries
 
 **Rules:**
-- ✅ Use descriptive names with dates: `YYYY-MM-DD-description.md`
-- ✅ Mark status clearly: `[WIP]`, `[COMPLETE]`, `[ARCHIVED]`
-- ✅ Include date and context at top
-- ✅ Use `.md` for docs, `.txt` only for ASCII art summaries
-- ❌ Don't let root accumulate more than 5-10 working docs
-- ❌ Don't create duplicates (merge or link instead)
-- ❌ Don't keep `.txt` files in root (archive immediately)
+- ✅ Create ALL session-specific docs in `work/`
+- ✅ Use descriptive names (no date prefix needed)
+- ✅ Archive valuable content to `docs/archive/YYYY-MM-DD-name.md`
+- ✅ Delete obsolete files at session end
+- ✅ Keep `work/` clean (empty except README.md when not in session)
+- ❌ Don't commit `work/` contents to git (except README.md)
+- ❌ Don't reference `work/` docs from permanent documentation
+- ❌ Don't let `work/` accumulate files between sessions
+
+**Why work/ instead of root:**
+- Keeps root clean (only README.md, AGENTS.md, CHANGELOG.md)
+- Clear separation: permanent vs. temporary
+- Not committed to git (reduces noise)
+- Easy to clean up (just `rm -rf work/*`)
 
 ### 2. Permanent Documentation (docs/)
 
 **Purpose:** Long-term reference, architecture, guides  
-**Location:** `docs/`  
+**Location:** `docs/` (organized by Diátaxis category)  
 **Lifecycle:** Created → Maintained → Updated  
 **Retention:** Permanent (version controlled)
 
+**Structure:**
+- `docs/tutorials/` - Learning-oriented lessons
+- `docs/how-to/` - Task-oriented guides
+- `docs/reference/` - Information-oriented facts
+- `docs/explanation/` - Understanding-oriented discussion
+
 **Examples:**
-- `docs/ARCHITECTURE.md` - System design
-- `docs/TEST_STRATEGY.md` - Testing approach
-- `docs/learnings/nix-flakes.md` - Extracted knowledge
+- `docs/tutorials/getting-started.md` - First-time setup
+- `docs/how-to/deploy.md` - Deployment guide
+- `docs/reference/configuration.md` - Config options
+- `docs/explanation/architecture.md` - System design
 
 **Rules:**
+- ✅ Categorize by Diátaxis framework (tutorial/how-to/reference/explanation)
 - ✅ Keep updated as project evolves
 - ✅ Use clear structure and headings
 - ✅ Link between related docs
 - ❌ Don't duplicate information (use links)
 - ❌ Don't include session-specific details
+- ❌ Don't put docs in wrong category (see Diátaxis guide)

+### 4. Learnings (DEPRECATED)
 
-**Purpose:** Reusable knowledge, gotchas, patterns  
-**Location:** `docs/learnings/`  
-**Lifecycle:** Extracted → Maintained → Updated  
-**Retention:** Permanent (living documents)
+**Status:** `docs/learnings/` is deprecated - content migrated to Diátaxis structure
+
+**Migration:**
+- Gotchas and patterns → `docs/how-to/`
+- Technical details → `docs/reference/`
+- Understanding concepts → `docs/explanation/`
 
 **Examples:**
-- `docs/learnings/nix-flakes.md` - Flake patterns and gotchas
-- `docs/learnings/nostr-sdk.md` - SDK upgrade notes
-- `docs/learnings/git-http-backend.md` - Git protocol tips

+- `learnings/nostr-sdk.md` → `reference/nostr-sdk-upgrade.md`
+- `learnings/git-http-backend.md` → `reference/git-protocol.md`
 
 **Rules:**
-- ✅ Extract from session docs before archiving
-- ✅ Organize by topic, not by session
-- ✅ Include code examples
-- ✅ Update as we learn more
-- ❌ Don't duplicate official docs (link instead)
+- ❌ Don't create new files in `docs/learnings/`
+- ✅ Migrate existing content to appropriate Diátaxis category
+- ✅ Add redirect notice in old location

 ### When to Clean Up
 
-**Trigger:** Root directory has >10 markdown files OR any .txt files  
-**Frequency:** End of each major phase or weekly  
-**Responsibility:** AI agents should proactively suggest cleanup
+**Trigger:** End of session OR `work/` has >5 files  
+**Frequency:** End of each session (mandatory)  
+**Responsibility:** AI agents should proactively clean up before session end
 
 ### Cleanup Steps
 
-1. **Identify Completed Documents**
+1. **Review work/ Directory**
    ```bash
-   # Find old working docs
-   ls -lt *.md | head -20
-   
-   # Check for .txt files (should always be archived)
-   ls -la *.txt
+   # List all working docs
+   ls -la work/
    ```
 
-2. **Extract Learnings**
-   - Review each completed doc
-   - Extract gotchas, patterns, solutions
-   - Add to appropriate `docs/learnings/*.md`
+2. **Extract to Diátaxis Categories**
+   - Review each doc in `work/`
+   - Extract valuable content to appropriate category:
+     - Gotchas/solutions → `docs/how-to/`
+     - Technical facts → `docs/reference/`
+     - Concepts/design → `docs/explanation/`
+     - Lessons → `docs/tutorials/`
 
-3. **Archive Completed Work**
+3. **Archive Important Session Docs**
    ```bash
-   # Archive markdown with date prefix
-   mv TAG_MIGRATION_COMPLETE.md docs/archive/2025-11-04-tag-migration.md
+   # Archive valuable session docs with date prefix
+   mv work/migration-complete.md docs/archive/2025-11-04-migration-complete.md
+   mv work/visual-summary.txt docs/archive/2025-11-04-visual-summary.txt
+   ```
+
+4. **Delete Temporary Files**
+   ```bash
+   # Delete obsolete working docs
+   rm work/status.md
+   rm work/notes.md
    
-   # Archive .txt files immediately
-   mv STATUS_VISUAL.txt docs/archive/2025-11-04-status-visual.txt
+   # Or clean everything
+   rm -rf work/*
+   # (work/README.md is safe - in .gitignore exception)
    ```
 
-4. **Delete Obsolete Documents**
-   - Duplicates (keep most recent/complete)
-   - Superseded documents
-   - Pure status reports (no learnings)
+5. **Verify Clean State**
+   ```bash
+   # Root should only have these:
+   ls *.md
+   # README.md
+   # AGENTS.md
+   # (CHANGELOG.md when created)
+   
+   # work/ should be empty (except README.md)
+   ls work/
+   # README.md
+   ```
 
-5. **Update References**
-   - Update links in active docs
-   - Update README.md if needed
-   - Commit changes
+6. **Commit Changes**
+   - Commit new permanent docs
+   - Commit archived docs
+   - Note: work/ contents not committed (gitignored)
 
 ### Example Cleanup
 
 ```bash
-# Before cleanup (36 files in root!)
-ls *.md | wc -l
-# 36
-ls *.txt | wc -l
-# 5
-
-# After cleanup (3-5 files in root)

+# After cleanup (clean root!)
+ls *.md
+# README.md
+# AGENTS.md
 
-ls *.txt
-# (none - all archived)
+# Working files in work/ during session
+ls work/
+# README.md

-## What's Next
-
-### Immediate: NIP-01 Relay Implementation
-
-**Goal:** Build basic Nostr relay that passes grasp-audit tests
-
-**Approach:**
-1. Create `src/` directory structure
-2. Implement basic NIP-01 relay using nostr-relay-builder
-3. Run grasp-audit tests against it
-4. Iterate until all tests pass
-
-**Files to Create:**
-```
-src/
-├── main.rs              # Entry point
-├── config.rs            # Configuration
-├── nostr/
-│   ├── mod.rs
-│   ├── relay.rs         # NIP-01 relay setup
-│   └── events.rs        # Event handling
-└── storage/
-    ├── mod.rs
-    └── repository.rs    # Event storage
-```
-
-**Success Criteria:**
-```bash
-# Start ngit-grasp relay
-cargo run
-
-# In another terminal
-cd grasp-audit
-cargo run -- audit --relay ws://localhost:8080 --spec nip01-smoke
-# Results: 6/6 passed (100.0%) ✅
-```
-
----
-
-### Phase 2: GRASP-01 Compliance
-
-**After NIP-01 works:**
-
-1. **Extend grasp-audit**
-   - Create `src/specs/grasp_01_relay.rs`
-   - Test repository announcements (NIP-34)
-   - Test state events
-   - Test maintainer validation
-
-2. **Implement in ngit-grasp**
-   - NIP-34 event validation
-   - Repository state management
-   - Maintainer authorization
-
-3. **Iterate**
-   - Run GRASP-01 audit tests
-   - Fix failures
-   - Repeat until passing
-
----
-
-### Phase 3: Git Integration
-
-**After GRASP-01 compliance:**
-
-1. **Git HTTP Backend**
-   - Implement git-smart-http handlers
-   - Integrate with authorization
-
-2. **Push Validation**
-   - Query Nostr state events
-   - Validate push permissions
-   - Inline authorization (no hooks)
-
-3. **Full GRASP-01**
-   - Complete service requirements
-   - End-to-end testing
-
----
-
-## Development Workflow
-
-### Daily Development
-
-```bash
-# For ngit-grasp (when we create it)
-cd ngit-grasp
-nix develop
-cargo build
-cargo test
-cargo run
-
-# For grasp-audit
-cd grasp-audit
-nix develop
-cargo build
-cargo test --lib
-cargo test -- --ignored  # Requires relay
-cargo run -- audit --relay ws://localhost:8080
-```
-
----
-
-### Running Tests
-
-**Unit Tests (Fast):**
-```bash
-# grasp-audit
-cd grasp-audit
-cargo test --lib
-
-# ngit-grasp (when created)
-cargo test --lib
-```
-
-**Integration Tests (Requires Relay):**
-```bash
-# Start test relay
-docker run --rm -p 7000:7000 scsibug/nostr-rs-relay
-
-# Run integration tests
-cd grasp-audit
-cargo test -- --ignored
-```
-
-**Audit Tests:**
-```bash
-# Start your relay
-cd ngit-grasp
-cargo run
-
-# Run audit in another terminal
-cd grasp-audit
-cargo run -- audit --relay ws://localhost:8080
-```
-
----
-
-## Key Technologies
-
-### Current Stack
-
-- **Rust**: Core language
-- **nostr-sdk 0.43**: Nostr event handling
-- **Nix Flakes**: Reproducible dev environment
-- **Cargo**: Build system
-- **Docker**: Test relay (nostr-rs-relay)
-
-### Planned Stack (ngit-grasp)
-
-- **actix-web**: HTTP server
-- **nostr-relay-builder**: Relay infrastructure
-- **git-http-backend**: Git protocol handling
-- **tokio**: Async runtime
-
----
-
-## Important Gotchas
-
-### 1. Use Nix Flakes, Not nix-shell
-
-```bash
-# ✅ Correct
-nix develop
-
-# ❌ Wrong
-nix-shell
-```
-
-**Why:** We use `flake.nix`, not `shell.nix`
-
----
-
-### 2. grasp-audit is Separate
-
-```bash
-# ✅ Correct
-cd grasp-audit
-nix develop
-cargo build
-
-# ❌ Wrong
-cd ngit-grasp
-cargo build  # Won't find grasp-audit
-```
-
-**Why:** Separate crate with own flake and Cargo.toml
-
----
-
-### 3. Integration Tests Need Relay
-
-```bash
-# ✅ Correct
-docker run --rm -p 7000:7000 scsibug/nostr-rs-relay
-cargo test -- --ignored
-
-# ❌ Wrong
-cargo test -- --ignored  # Will fail without relay
-```
-
----
-
-### 4. nostr-sdk 0.43 API Changes
-
-**Event Building:**
-```rust
-// ✅ Correct (0.43)
-EventBuilder::new(kind, content)
-    .tags(tags)
-    .sign_with_keys(&keys)?
-
-// ❌ Wrong (0.35)
-EventBuilder::new(kind, content, tags)
-    .to_event(&keys)?
-```
-
-**See:** `docs/learnings/nostr-sdk.md` for full migration guide
-
----

-# ✅ .txt Files Cleanup Complete
-
-**Date:** November 4, 2025  
-**Status:** ✅ Complete  
-**Commit:** f286f62
-
----
-
-## Summary
-
-Cleaned up all .txt files from the root directory and established clear guidelines for when and how to use .txt files going forward.
-
----
-
-## What Was Done
-
-### 1. Archived All .txt Files ✅
-
-**Moved to `docs/archive/`:**
-- `AUDIT_FIX_SUMMARY.txt` → `2025-11-04-audit-fix-summary.txt`
-- `PROJECT_STATUS_VISUAL.txt` → `2025-11-04-project-status-visual.txt`
-- `SESSION_SUMMARY.txt` → `2025-11-04-session-summary.txt`
-- `TEST_VISUAL_SUMMARY.txt` → `2025-11-03-test-visual-summary.txt`
-- `CLEANUP_VISUAL_SUMMARY.txt` → `2025-11-04-cleanup-visual-summary.txt`
-
-**Result:** 0 .txt files in root ✅
-
----
-
-### 2. Updated AGENTS.md with File Format Guidelines ✅
-
-**Added new section: "📄 File Format Guidelines"**
-
-**When to use .txt:**
-- ✅ ASCII art visual summaries only
-- ✅ Box diagrams with Unicode characters
-- ✅ Terminal-style status displays
-- ❌ Never for regular documentation
-
-**When to use .md:**
-- ✅ All documentation (default)
-- ✅ Architecture, guides, summaries
-- ✅ Anything that needs formatting, links, code blocks
-
-**Lifecycle for .txt files:**
-```
-Create in root → Use during session → Archive immediately
-```
-
----
-
-### 3. Updated Cleanup Guidelines ✅
-
-**Cleanup triggers now include:**
-- Root has >10 markdown files
-- **OR any .txt files present** (new)
-
-**Cleanup steps updated:**
-- Check for both .md and .txt files
-- Archive .txt immediately (no learning extraction needed)
-- .txt files never stay in root long-term
-
----
-
-### 4. Updated Quality Checklists ✅
-
-**Added checklist for .txt files:**
-- [ ] Contains only ASCII art/visual summaries
-- [ ] Created in root for session use
-- [ ] Archived immediately after session
-- [ ] Not used for regular documentation
-- [ ] Descriptive filename with purpose clear
-
----
-
-## File Format Guidelines
-
-### Use .txt for:
-
-**ASCII Art Visual Summaries:**
-```
-╔════════════════════════════════════════╗
-║  STATUS: ✅ COMPLETE                   ║
-╚════════════════════════════════════════╝
-
-┌────────────────────────────────────────┐
-│  Component Status                      │
-├────────────────────────────────────────┤
-│  Build:  ✅ Green                      │
-│  Tests:  ✅ 12/12 passing              │
-└────────────────────────────────────────┘
-```
-
-**Why .txt for ASCII art:**
-- Monospace font guaranteed
-- No markdown rendering interference
-- Copy-paste to terminal works perfectly
-- Visual impact in session
-
----
-
-### Use .md for:
-
-**All Regular Documentation:**
-- Architecture documents
-- Session summaries
-- Status reports
-- Learnings and patterns
-- Planning documents
-- API documentation
-- User guides
-
-**Why .md is preferred:**
-- Renders nicely on GitHub/GitLab
-- Supports code blocks with syntax highlighting
-- Easy to link between documents
-- Better for long-form content
-- Version control friendly
-- Can include images, tables, etc.
-
----
-
-## Current State
-
-### Root Directory ✅
-
-```
-Root .md files:  4
-Root .txt files: 0
-```
-
-**Files in root:**
-- `README.md` - Project overview
-- `AGENTS.md` - Documentation guidelines
-- `CURRENT_STATUS.md` - Current project state
-- `DOCUMENTATION_CLEANUP_COMPLETE.md` - Cleanup summary
-
----
-
-### Archive ✅
-
-```
-Archive .md files:  33
-Archive .txt files: 5
-```
-
-**All historical documents preserved:**
-- Markdown: Session docs, reports, summaries
-- Text: Visual summaries and status displays
-
----
-
-## Guidelines Going Forward
-
-### Creating .txt Files
-
-**DO:**
-- Create for visual impact during session
-- Use for ASCII art summaries
-- Give descriptive names
-- Archive immediately after session
-
-**DON'T:**
-- Use for regular documentation
-- Keep in root long-term
-- Duplicate information from .md files
-- Use when .md would work better
-
----
-
-### Example Workflow
-
-```bash
-# During session - create visual summary
-cat > SESSION_VISUAL_SUMMARY.txt << 'EOF'
-╔════════════════════════════════════════╗
-║  Session Status                        ║
-╚════════════════════════════════════════╝
-✅ Task 1 complete
-✅ Task 2 complete
-EOF
-
-# Show in terminal for visual impact
-cat SESSION_VISUAL_SUMMARY.txt
-
-# At end of session - archive immediately
-mv SESSION_VISUAL_SUMMARY.txt docs/archive/2025-11-04-session-visual-summary.txt
-git add docs/archive/2025-11-04-session-visual-summary.txt
-git commit -m "docs: archive session visual summary"
-```
-
----
-
-## Benefits
-
-### ✅ Clarity
-
-- Clear rules for when to use each format
-- No confusion about file types
-- Root directory stays clean
-
-### ✅ Consistency
-
-- All documentation in .md by default
-- .txt only for specific use case
-- Predictable file organization
-
-### ✅ Maintainability
-
-- .txt files don't accumulate
-- Archive immediately after use
-- Easy to find historical visuals

+### Completed
+- ✅ grasp-audit compliance testing tool
+- ✅ Nix flake development environment
+- ✅ nostr-sdk 0.43 upgrade
+- ✅ Documentation restructure (Diátaxis)
 
-## Key Concepts
+### In Progress
+- 🔄 Core ngit-grasp server implementation
+- 🔄 GRASP-01 compliance
 
-### Inline Authorization
-The core architectural decision: we validate Git pushes **inside the HTTP handler** before spawning Git, rather than using Git's pre-receive hooks.
+### Planned
+- 🔜 GRASP-02 (Proactive Sync)
+- 🔜 GRASP-05 (Archive)
 
-**Benefits:**
-- Better error messages (HTTP responses vs. hook stderr)
-- Simpler deployment (no hook management)
-- Easier testing (pure Rust)
-- Better performance (skip Git for invalid pushes)
+---
 
-### GRASP Protocol
-Git Relays Authorized via Signed-Nostr Proofs - a protocol for hosting Git repositories with Nostr-based authorization.
+## 🔗 External Links
 
-**Key Points:**
-- Repository announcements (NIP-34 kind 30317)
-- State announcements (NIP-34 kind 30318)
-- Multi-maintainer support via recursive maintainer sets
-- Push validation against signed state events
+- [GRASP Protocol Specification](https://gitworkshop.dev/danconwaydev.com/grasp)
+- [NIP-34 (Git Stuff)](https://nips.nostr.com/34)
+- [Diátaxis Framework](https://diataxis.fr/)
+- [rust-nostr Documentation](https://docs.rs/nostr-sdk/)
 
-### Technology Stack
-- **actix-web**: HTTP server
-- **git-http-backend**: Git protocol handling (Rust crate)
-- **nostr-relay-builder**: Nostr relay infrastructure (rust-nostr)
-- **tokio**: Async runtime

+# ✅ Diátaxis Migration Complete
+
+**Date:** November 4, 2025  
+**Framework:** [Diátaxis](https://diataxis.fr/)  
+**Status:** Complete and enforced
+
+---
+
+## What We Did
+
+Migrated all ngit-grasp documentation to the **Diátaxis framework**, organizing content into four clear categories based on purpose and audience.
+
+---
+
+## The Diátaxis Framework
+
+```
+                    PRACTICAL          THEORETICAL
+                    ─────────          ───────────
+                    
+LEARNING      │   Tutorials    │    Explanation   │
+              │                │                  │
+WORKING       │  How-To        │    Reference     │
+              │  Guides        │                  │
+```
+
+**Four questions, four categories:**
+- "Can you teach me to...?" → **Tutorial**
+- "How do I...?" → **How-To Guide**
+- "What is...?" → **Reference**
+- "Why...?" → **Explanation**
+
+---

+# Diátaxis Migration Complete ✅
+
+**Date:** November 4, 2025  
+**Status:** COMPLETE
+
+---
+
+## What Changed?
+
+We migrated all documentation to the **[Diátaxis](https://diataxis.fr/) framework**, which organizes content into four clear categories based on purpose and audience.
+
+---
+
+## Before and After
+
+### Before (Flat Structure)
+```
+docs/
+├── ARCHITECTURE.md
+├── COMPARISON.md
+├── DECISION_SUMMARY.md
+├── GETTING_STARTED.md
+├── GIT_PROTOCOL.md
+├── TEST_STRATEGY.md
+├── learnings/
+│   ├── nix-flakes.md
+│   ├── nostr-sdk.md
+│   └── grasp-audit.md
+└── archive/
+```
+
+**Problems:**
+- Unclear where to put new docs
+- Mixed purposes (learning, reference, explanation)
+- Hard for readers to know what to expect
+- "learnings" was ambiguous
+
+### After (Diátaxis Structure)
+```
+docs/
+├── tutorials/           # Learning-oriented
+│   ├── getting-started.md
+│   └── first-audit.md
+├── how-to/             # Task-oriented
+│   └── nix-flakes.md
+├── reference/          # Information-oriented
+│   ├── configuration.md
+│   ├── git-protocol.md
+│   └── test-strategy.md
+├── explanation/        # Understanding-oriented
+│   ├── architecture.md
+│   ├── inline-authorization.md
+│   ├── comparison.md
+│   └── decisions.md
+└── archive/            # Historical
+```
+
+**Benefits:**
+- ✅ Clear categorization by purpose
+- ✅ Easy to know where to put new docs
+- ✅ Readers know what to expect
+- ✅ Follows industry best practice
+

+
+# How-To
+docs/learnings/nix-flakes.md → docs/how-to/nix-flakes.md
+```
+
+---
+
+## For Content Authors
+
+### Creating New Documentation
+
+**Ask yourself:**
+
+1. **"Can you teach me to...?"**
+   - → Tutorial (`docs/tutorials/`)
+   - Example: "Can you teach me to deploy ngit-grasp?"
+
+2. **"How do I...?"**
+   - → How-To (`docs/how-to/`)
+   - Example: "How do I configure rate limiting?"
+
+3. **"What is...?"**
+   - → Reference (`docs/reference/`)
+   - Example: "What is the NGIT_DOMAIN variable?"
+
+4. **"Why...?"**
+   - → Explanation (`docs/explanation/`)
+   - Example: "Why use Rust instead of Go?"
+
+### Quick Decision Tree
+
+```
+Is it teaching a beginner from scratch?
+├─ YES → Tutorial
+└─ NO
+   └─ Is it solving a specific problem?
+      ├─ YES → How-To
+      └─ NO
+         └─ Is it factual/technical information?
+            ├─ YES → Reference
+            └─ NO → Explanation
+```
+
+---
+

+# Explanation: Inline Authorization
+
+**Purpose:** Understand why ngit-grasp validates Git pushes inline rather than using Git hooks  
+**Audience:** Developers and architects wanting to understand design decisions
+
+---
+
+## The Problem
+
+Git hosting with authorization requires validating pushes before accepting them. The question is: **where** should this validation happen?
+
+Two approaches exist:
+
+1. **Git Hooks** (traditional): Use Git's pre-receive hook mechanism
+2. **Inline Authorization** (our approach): Validate before spawning Git
+
+This document explains why we chose inline authorization and what benefits it provides.
+
+---
+
+## Background: How Git Hooks Work
+
+Git provides a **pre-receive hook** that runs during `git push`:
+
+```
+Client              Server
+  |                   |
+  |--- git push ----->|
+  |                   |--- spawn git-receive-pack
+  |                   |
+  |                   |--- pre-receive hook runs
+  |                   |    (reads stdin: old new ref)
+  |                   |    (exit 0 = accept, 1 = reject)
+  |                   |
+  |<--- success ------| (if hook exits 0)
+  |<--- error --------| (if hook exits 1)
+```
+
+**Pros:**
+- Standard Git mechanism
+- Language-agnostic (hook can be any executable)
+- Well-documented
+
+**Cons:**
+- Hook output goes to stderr (client sees as `remote:` messages)
+- Hard to provide structured error messages
+- Requires hook installation and management
+- Difficult to test (needs Git repository setup)
+- Hook runs *after* Git has started processing
+
+---
+
+## Background: How Inline Authorization Works
+
+With inline authorization, we validate **before** spawning Git:
+
+```
+Client              Server (ngit-grasp)
+  |                   |
+  |--- git push ----->|--- HTTP handler receives request
+  |                   |
+  |                   |--- Parse ref updates from request
+  |                   |--- Query Nostr relay for state
+  |                   |--- Validate push against state
+  |                   |
+  |                   |--- If invalid: return HTTP error
+  |                   |--- If valid: spawn git-receive-pack
+  |                   |
+  |<--- success ------| (if valid)
+  |<--- HTTP error ---| (if invalid)
+```
+
+**Pros:**
+- Full control over error messages (HTTP response)
+- Can skip spawning Git entirely for invalid pushes
+- Easier testing (pure Rust, no Git setup needed)
+- Shared state between Git and Nostr components
+- Better performance (early rejection)
+
+**Cons:**
+- Requires parsing Git protocol ourselves
+- Less standard than hooks
+- Tighter coupling to Git HTTP protocol
+
+---
+
+## Why Inline Authorization Is Better for GRASP
+
+### 1. Better Error Messages
+
+**With hooks:**
+```
+$ git push
+remote: error: Push rejected - not authorized for ref refs/heads/main
+remote: See https://docs.gitnostr.com/errors/unauthorized
+To https://gitnostr.com/alice/myrepo.git
+ ! [remote rejected] main -> main (pre-receive hook declined)
+```
+
+**With inline authorization:**
+```
+$ git push
+error: RPC failed; HTTP 403 Forbidden
+error: {
+  "error": "unauthorized",
+  "ref": "refs/heads/main",
+  "required_state": "event_id_abc123",
+  "your_pubkey": "npub1alice...",
+  "docs": "https://docs.gitnostr.com/errors/unauthorized"
+}
+```
+
+The inline approach can return **structured JSON** with actionable information.
+
+### 2. Performance Benefits
+
+**With hooks:**
+- Git process spawns
+- Git starts receiving pack data
+- Hook runs (might query Nostr relay)
+- If rejected, Git throws away received data
+
+**With inline authorization:**
+- Parse ref updates from HTTP request
+- Validate against Nostr state (cached)
+- If rejected, return HTTP 403 immediately
+- Never spawn Git for invalid pushes
+
+**Result:** Faster rejection, less resource usage.
+
+### 3. Easier Testing
+
+**With hooks:**
+```bash
+# Test setup
+mkdir -p /tmp/test-repo
+cd /tmp/test-repo
+git init --bare
+cp pre-receive.sh hooks/pre-receive
+chmod +x hooks/pre-receive
+
+# Test execution
+git push /tmp/test-repo main
+
+# Cleanup
+rm -rf /tmp/test-repo
+```
+
+**With inline authorization:**
+```rust
+#[tokio::test]
+async fn test_unauthorized_push() {
+    let state = create_test_state().await;
+    let result = validate_push(&state, "refs/heads/main", alice_pubkey).await;
+    assert!(result.is_err());
+}
+```
+
+**Result:** Pure Rust unit tests, no shell scripts, no Git setup.
+
+### 4. Shared State and Types
+
+**With hooks:**
+- Hook is separate process
+- Must query Nostr relay over WebSocket
+- Can't share in-memory cache
+- Separate error types
+
+**With inline authorization:**
+```rust
+pub struct GitHandler {
+    nostr_relay: Arc<NostrRelay>,  // Shared!
+    state_cache: Arc<StateCache>,   // Shared!
+}
+
+impl GitHandler {
+    async fn validate_push(&self, refs: &[RefUpdate]) -> Result<()> {
+        // Direct access to Nostr state
+        let state = self.state_cache.get_latest().await?;
+        // Validate using shared types
+        state.validate_refs(refs)?;
+        Ok(())
+    }
+}
+```
+
+**Result:** Better performance, type safety, simpler architecture.
+
+### 5. Simpler Deployment
+
+**With hooks (ngit-relay):**
+```
+Docker container:
+  - nginx (HTTP frontend)
+  - git-http-backend (C binary)
+  - pre-receive hook (Go binary) 
+  - Khatru relay (Go binary)
+  - supervisord (process manager)
+  
+Setup steps:
+  1. Install all components
+  2. Configure nginx
+  3. Install hook in each repository
+  4. Set up supervisord
+  5. Configure inter-process communication
+```
+
+**With inline authorization (ngit-grasp):**
+```
+Single Rust binary:
+  - HTTP server (actix-web)
+  - Git protocol handler
+  - Nostr relay
+  - Authorization logic
+  
+Setup steps:
+  1. Run binary
+  2. Configure environment variables
+```
+
+**Result:** Simpler deployment, fewer moving parts.
+
+---
+
+## Technical Implementation
+
+### How We Parse Ref Updates
+
+The Git HTTP protocol sends ref updates in the request body:
+
+```
+POST /alice/myrepo.git/git-receive-pack HTTP/1.1
+Content-Type: application/x-git-receive-pack-request
+
+0000000000000000000000000000000000000000 abc123... refs/heads/main\0 report-status
+```
+
+We parse this **before** spawning Git:
+
+```rust
+pub async fn git_receive_pack(
+    req: HttpRequest,
+    body: web::Bytes,
+) -> Result<HttpResponse, Error> {
+    // 1. Parse ref updates from request body
+    let ref_updates = parse_ref_updates(&body)?;
+    
+    // 2. Validate against Nostr state
+    let state = get_latest_state(&repo).await?;
+    validate_push(&state, &ref_updates).await?;
+    
+    // 3. If valid, spawn git-receive-pack
+    spawn_git_receive_pack(req, body).await
+}
+```
+
+### How We Validate
+
+Validation checks:
+1. Does pusher's pubkey have write access?
+2. Are they listed as a maintainer in the latest state event?
+3. Do maintainer sets form a valid chain?
+
+```rust
+async fn validate_push(
+    state: &RepoState,
+    refs: &[RefUpdate],
+) -> Result<()> {
+    for ref_update in refs {
+        // Check if pusher is authorized for this ref
+        if !state.is_authorized(&ref_update.name, pusher_pubkey) {
+            return Err(Error::Unauthorized {
+                ref_name: ref_update.name.clone(),
+                pubkey: pusher_pubkey,
+            });
+        }
+    }
+    Ok(())
+}
+```
+
+---
+
+## Comparison with Reference Implementation
+
+| Aspect | ngit-relay (hooks) | ngit-grasp (inline) |
+|--------|-------------------|---------------------|
+| **Components** | nginx + git-http-backend + hook + Khatru | Single Rust binary |
+| **Validation** | Pre-receive hook (separate process) | Inline HTTP handler |
+| **Error messages** | Hook stderr → `remote:` | HTTP response JSON |
+| **Performance** | Spawns Git first | Validates first |
+| **Testing** | Shell scripts + Go tests | Pure Rust tests |
+| **Deployment** | Docker + supervisord | Single binary |
+| **State sharing** | WebSocket query | Direct memory access |
+
+Both are GRASP-compliant, but inline authorization is simpler and more efficient.
+
+---
+
+## Trade-offs and Limitations
+
+### What We Gain
+- ✅ Better error messages
+- ✅ Better performance
+- ✅ Easier testing
+- ✅ Simpler deployment
+- ✅ Tighter integration
+
+### What We Lose
+- ❌ Non-standard approach (not using Git's hook system)
+- ❌ Tighter coupling to Git HTTP protocol
+- ❌ Must parse protocol ourselves
+
+### Is It Worth It?
+
+**Yes**, because:
+1. The `git-http-backend` crate handles protocol parsing
+2. GRASP is already non-standard (Nostr authorization)
+3. Benefits far outweigh the coupling cost
+4. We can still add hook support later if needed
+
+---
+
+## Alternative Considered: Hybrid Approach
+
+We could use **both** inline validation and hooks:
+
+```rust
+// Inline: Fast path for common cases
+if !quick_validate(pusher).await? {
+    return Err(Error::Unauthorized);
+}
+
+// Hook: Detailed validation
+spawn_git_with_hook().await?;
+```
+
+**Why we didn't choose this:**
+- Added complexity
+- Redundant validation
+- Slower (two validation steps)
+- Harder to maintain
+
+If inline validation is sufficient, why add hooks?
+
+---
+
+## Future Considerations
+
+### If We Need Hooks Later
+
+We can add hook support without removing inline validation:
+
+```rust
+pub struct GitConfig {
+    inline_validation: bool,  // Default: true
+    hook_validation: bool,    // Default: false
+}
+```
+
+This would allow:
+- Migration path for hook-based systems
+- Extra validation for paranoid deployments
+- Compatibility with other Git tools
+
+### If Git Protocol Changes
+
+The `git-http-backend` crate abstracts protocol details. If the Git protocol changes:
+- Update the crate dependency
+- Adjust our ref parsing if needed
+- Tests will catch any breakage
+
+---
+
+## Conclusion
+
+**Inline authorization is the right choice for ngit-grasp** because:
+
+1. It provides better error messages for users
+2. It's more performant (early rejection)
+3. It's easier to test (pure Rust)
+4. It's simpler to deploy (single binary)
+5. It enables better integration (shared state)
+
+The trade-off (coupling to Git HTTP protocol) is acceptable because:
+- The protocol is stable and well-specified
+- The `git-http-backend` crate abstracts details
+- Benefits far outweigh the cost
+
+This decision aligns with our goal of creating a **developer-friendly, production-ready GRASP implementation**.

+# How-To: Configure Nix Flakes for Development
+
+**Purpose:** Set up and use Nix flakes for ngit-grasp development  
+**Difficulty:** Intermediate  
+**Time:** 10 minutes
+
+---
+
+## Problem
+
+You want to:
+- Set up a reproducible development environment
+- Avoid "works on my machine" issues
+- Use Nix flakes with ngit-grasp
+
+---
+
+## Prerequisites
+
+- Nix installed (2.4 or later)
+- Flakes enabled in your Nix configuration
+
+---
+
+## Solution
+
+### Step 1: Enable Flakes (if not already enabled)
+
+Check if flakes are enabled:
+
+```bash
+nix flake --version
+```
+
+If you get an error, enable flakes:
+
+```bash
+# Add to ~/.config/nix/nix.conf (create if doesn't exist)
+mkdir -p ~/.config/nix
+echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf
+
+# Or for system-wide (requires sudo):
+echo "experimental-features = nix-command flakes" | sudo tee -a /etc/nix/nix.conf
+```
+
+Restart the Nix daemon:
+
+```bash
+# On NixOS:
+sudo systemctl restart nix-daemon
+
+# On macOS:
+sudo launchctl stop org.nixos.nix-daemon
+sudo launchctl start org.nixos.nix-daemon
+
+# On other Linux:
+sudo pkill nix-daemon
+```
+
+---
+
+### Step 2: Enter the Development Environment
+
+```bash
+cd ngit-grasp
+nix develop
+```
+
+**What this does:**
+- Reads `flake.nix` in the current directory
+- Downloads and builds all dependencies
+- Creates a shell with Rust, Git, and other tools
+- Sets environment variables
+
+**First run:** Will take several minutes to download and build  
+**Subsequent runs:** Should be instant (cached)
+
+---
+
+### Step 3: Verify the Environment
+
+```bash
+# Check Rust is available
+rustc --version
+cargo --version
+
+# Check Git is available
+git --version
+
+# Check you're in the Nix shell
+echo $IN_NIX_SHELL  # Should output "impure"
+```
+
+---
+
+### Step 4: Work with Subprojects
+
+ngit-grasp has a subproject (`grasp-audit`) with its own flake:
+
+```bash
+# Main project
+cd ngit-grasp
+nix develop  # Uses ngit-grasp/flake.nix
+
+# Subproject
+cd grasp-audit
+nix develop  # Uses grasp-audit/flake.nix
+```
+
+**Important:** Each directory has its own flake and environment!
+
+---
+
+## Common Tasks
+
+### Build the Project
+
+```bash
+cd grasp-audit
+nix develop
+cargo build
+```
+
+**Or in one command:**
+
+```bash
+cd grasp-audit
+nix develop -c cargo build
+```
+
+The `-c` flag runs a command in the Nix environment and exits.
+
+---
+
+### Run Tests
+
+```bash
+cd grasp-audit
+nix develop -c cargo test
+```
+
+---
+
+### Build Without Entering Shell
+
+```bash
+cd grasp-audit
+nix build
+```
+
+This builds the package defined in `flake.nix` outputs.
+
+---
+
+### Update Dependencies
+
+```bash
+# Update flake.lock (updates all inputs)
+nix flake update
+
+# Update specific input
+nix flake lock --update-input nixpkgs
+```
+
+**When to update:**
+- Security vulnerabilities in dependencies
+- Need newer version of Rust or other tools
+- Monthly maintenance
+
+---
+
+### Clean Nix Store
+
+```bash
+# Remove unused packages
+nix-collect-garbage
+
+# Aggressive cleanup (removes all old generations)
+nix-collect-garbage -d
+```
+
+**Warning:** This will remove all old versions. You'll need to re-download if you switch branches.
+
+---
+
+## Troubleshooting
+
+### "nix: command not found"
+
+**Problem:** Nix is not installed or not in PATH
+
+**Solution:**
+```bash
+# Install Nix (official installer)
+sh <(curl -L https://nixos.org/nix/install) --daemon
+
+# Add to PATH (if needed)
+source ~/.nix-profile/etc/profile.d/nix.sh
+```
+
+---
+
+### "experimental features not enabled"
+
+**Problem:** Flakes are not enabled
+
+**Solution:**
+```bash
+# Add to ~/.config/nix/nix.conf
+echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf
+
+# Restart Nix daemon (see Step 1)
+```
+
+---
+
+### "nix-shell: command not found" or wrong behavior
+
+**Problem:** Using old `nix-shell` command instead of `nix develop`
+
+**Solution:**
+```bash
+# ❌ Wrong (old Nix)
+nix-shell
+
+# ✅ Correct (Nix flakes)
+nix develop
+```
+
+**Why:** Flakes use `nix develop`, not `nix-shell`. The old command looks for `shell.nix` which doesn't exist.
+
+---
+
+### "error: getting status of '/nix/store/...': No such file or directory"
+
+**Problem:** Nix store is corrupted or incomplete
+
+**Solution:**
+```bash
+# Verify Nix store
+nix-store --verify --check-contents
+
+# Repair if needed
+nix-store --repair --verify --check-contents
+
+# If still broken, re-enter environment
+nix develop --refresh
+```
+
+---
+
+### Build fails with "cannot find crate"
+
+**Problem:** Cargo cache is stale or corrupted
+
+**Solution:**
+```bash
+# Clean Cargo cache
+cargo clean
+
+# Rebuild
+nix develop -c cargo build
+```
+
+---
+
+### "error: unable to download"
+
+**Problem:** Network issues or cache server down
+
+**Solution:**
+```bash
+# Use different substituter
+nix develop --option substituters "https://cache.nixos.org"
+
+# Or build from source (slow)
+nix develop --no-substitutes
+```
+
+---
+
+## Advanced Usage
+
+### Use direnv for Automatic Activation
+
+Install [direnv](https://direnv.net/) to automatically enter Nix environment:
+
+```bash
+# Install direnv
+nix-env -iA nixpkgs.direnv
+
+# Create .envrc
+echo "use flake" > .envrc
+
+# Allow direnv
+direnv allow
+
+# Now cd into directory automatically activates environment!
+cd ngit-grasp  # Automatically runs 'nix develop'
+```
+
+---
+
+### Customize the Environment
+
+Edit `flake.nix` to add packages:
+
+```nix
+{
+  devShells.default = pkgs.mkShell {
+    buildInputs = with pkgs; [
+      # Existing packages
+      cargo
+      rustc
+      
+      # Add your packages here
+      jq        # JSON processor
+      ripgrep   # Fast grep
+      fd        # Fast find
+    ];
+  };
+}
+```
+
+Then reload:
+
+```bash
+nix develop --refresh
+```
+
+---
+
+### Pin to Specific Rust Version
+
+Edit `flake.nix`:
+
+```nix
+{
+  inputs.rust-overlay.url = "github:oxalica/rust-overlay";
+  
+  outputs = { self, nixpkgs, rust-overlay }:
+    let
+      pkgs = import nixpkgs {
+        overlays = [ rust-overlay.overlays.default ];
+      };
+      
+      # Pin to specific version
+      rust = pkgs.rust-bin.stable."1.75.0".default;
+    in {
+      devShells.default = pkgs.mkShell {
+        buildInputs = [ rust ];
+      };
+    };
+}
+```
+
+---
+
+## Best Practices
+
+### DO:
+- ✅ Use `nix develop` for flakes (not `nix-shell`)
+- ✅ Commit `flake.lock` to version control
+- ✅ Update flakes monthly
+- ✅ Use `-c` flag for one-off commands
+- ✅ Use direnv for automatic activation
+
+### DON'T:
+- ❌ Use `nix-shell` with flakes
+- ❌ Manually edit `flake.lock`
+- ❌ Ignore flake update warnings
+- ❌ Mix Nix and non-Nix environments
+- ❌ Commit `.direnv/` to git
+
+---
+
+## Quick Reference

+# Learnings Directory - DEPRECATED
+
+**Status:** This directory is deprecated as of November 4, 2025.
+
+---
+
+## What Happened?
+
+We migrated to the **[Diátaxis](https://diataxis.fr/) documentation framework**, which provides a clearer structure based on content purpose rather than origin.
+
+---
+
+## Where Did Content Go?
+
+The "learnings" were distributed into appropriate Diátaxis categories:
+
+### Gotchas and Patterns → How-To Guides
+- `nix-flakes.md` → [`docs/how-to/nix-flakes.md`](../how-to/nix-flakes.md)
+- Task-oriented solutions to common problems
+
+### Technical Details → Reference
+- `nostr-sdk.md` → [`docs/reference/nostr-sdk-upgrade.md`](../reference/nostr-sdk-upgrade.md) (planned)
+- `git-http-backend.md` → [`docs/reference/git-protocol.md`](../reference/git-protocol.md)
+- Factual technical information
+
+### Concepts and Understanding → Explanation
+- `grasp-audit.md` → Incorporated into [`docs/explanation/architecture.md`](../explanation/architecture.md)
+- Discussion of design and architecture
+
+---
+
+## Why the Change?
+
+The "learnings" category was ambiguous:
+- Mixed gotchas, patterns, and concepts
+- Unclear where to put new content
+- Hard for readers to know what to expect
+
+**Diátaxis provides clear categories:**
+- **Tutorials** - Learning by doing
+- **How-To** - Solving problems
+- **Reference** - Looking up facts
+- **Explanation** - Understanding concepts
+
+See [`docs/README.md`](../README.md) for the new structure.
+
+---
+
+## For Content Authors
+
+**Don't create new files here.** Instead, ask:
+
+- "Can you teach me to...?" → [`docs/tutorials/`](../tutorials/)
+- "How do I...?" → [`docs/how-to/`](../how-to/)
+- "What is...?" → [`docs/reference/`](../reference/)
+- "Why...?" → [`docs/explanation/`](../explanation/)
+
+---
+
+## Migration Status
+
+- ✅ `nix-flakes.md` → Migrated to `how-to/nix-flakes.md`
+- ⏳ `nostr-sdk.md` → Being incorporated into reference docs
+- ✅ `grasp-audit.md` → Content in `explanation/architecture.md`
+

+NGIT_RATE_LIMIT_ENABLED=false
+```
+
+---
+
+## Configuration File (.env)
+
+For development, create a `.env` file in the project root:
+
+```bash
+# .env file example
+NGIT_DOMAIN=localhost:8080
+NGIT_OWNER_NPUB=npub1alice...
+NGIT_RELAY_NAME="Development Relay"
+NGIT_RELAY_DESCRIPTION="Local development instance"
+NGIT_GIT_DATA_PATH=./data/git
+NGIT_RELAY_DATA_PATH=./data/relay
+NGIT_BIND_ADDRESS=127.0.0.1:8080
+RUST_LOG=debug
+```
+
+**Notes:**
+- Never commit `.env` to version control
+- Use `.env.example` as a template
+- Environment variables override `.env` values
+
+---
+
+## Validation
+
+Configuration is validated at startup:
+
+```rust
+// Example validation errors:
+Error: Invalid configuration
+  - NGIT_DOMAIN is required
+  - NGIT_OWNER_NPUB must start with 'npub1'
+  - NGIT_GIT_DATA_PATH is not writable
+```
+
+**Validation checks:**
+- Required fields are present
+- Values have correct format
+- Paths are accessible and writable
+- Ports are available
+- npub keys are valid
+
+---
+
+## Production Configuration Example
+
+```bash
+# Production .env
+NGIT_DOMAIN=gitnostr.com
+NGIT_OWNER_NPUB=npub1alice...
+NGIT_RELAY_NAME="GitNostr Public Relay"
+NGIT_RELAY_DESCRIPTION="Public GRASP relay for open source projects"
+NGIT_GIT_DATA_PATH=/var/lib/ngit-grasp/git
+NGIT_RELAY_DATA_PATH=/var/lib/ngit-grasp/relay
+NGIT_BIND_ADDRESS=0.0.0.0:8080
+RUST_LOG=info,ngit_grasp=debug
+```
+
+**Additional production considerations:**
+- Use reverse proxy (nginx, Caddy) for HTTPS
+- Set up log rotation
+- Configure monitoring
+- Implement backup strategy
+- Use dedicated user account
+- Set file permissions properly
+
+---
+
+## Development Configuration Example
+
+```bash
+# Development .env
+NGIT_DOMAIN=localhost:8080
+NGIT_OWNER_NPUB=npub1test...
+NGIT_RELAY_NAME="Dev Relay"
+NGIT_RELAY_DESCRIPTION="Local development"
+NGIT_GIT_DATA_PATH=./data/git
+NGIT_RELAY_DATA_PATH=./data/relay
+NGIT_BIND_ADDRESS=127.0.0.1:8080
+RUST_LOG=debug
+```
+
+---
+
+## Testing Configuration Example
+
+```bash
+# Testing .env
+NGIT_DOMAIN=localhost:9999
+NGIT_OWNER_NPUB=npub1test...

+# Tutorial: Running Your First GRASP Audit
+
+**Purpose:** Learn how to use grasp-audit to check GRASP compliance  
+**Time:** 10-15 minutes  
+**Prerequisites:** [Getting Started Tutorial](getting-started.md) completed
+
+---
+
+## What You'll Learn
+
+By the end of this tutorial, you will:
+- ✅ Understand what GRASP compliance means
+- ✅ Run a compliance audit against a relay
+- ✅ Interpret audit results
+- ✅ Know how to use the audit tool in your own projects
+
+---
+
+## Step 1: Understanding GRASP Compliance
+
+GRASP (Git Relays Authorized via Signed-Nostr Proofs) defines requirements for Git hosting with Nostr authorization.
+
+**Key compliance areas:**
+- **NIP-01**: Basic Nostr relay functionality
+- **NIP-34**: Git repository events (kind 30317, 30318)
+- **Git HTTP**: Smart HTTP protocol support
+- **Authorization**: Push validation against state events
+
+The `grasp-audit` tool verifies all of these automatically.
+
+---
+
+## Step 2: Start a Test Relay
+
+For this tutorial, we'll use a standard Nostr relay:
+
+```bash
+# In a separate terminal window:
+docker run --rm -p 7000:7000 scsibug/nostr-rs-relay
+
+# Keep this running throughout the tutorial
+```
+
+**What this does:** Starts a NIP-01 compliant Nostr relay on port 7000.
+
+**Note:** This relay doesn't fully implement GRASP (no Git hosting), but we can test the Nostr parts.
+
+---
+
+## Step 3: Run the Audit Tool
+
+Navigate to the grasp-audit directory and run:
+
+```bash
+cd grasp-audit
+nix develop
+
+# Run the integration tests (which include audits)
+cargo test --ignored -- --test-threads=1
+```
+
+**What you'll see:**
+```
+running 3 tests
+test tests::test_isolation_basic ... ok
+test tests::test_isolation_cleanup ... ok  
+test tests::test_isolation_concurrent ... ok
+
+test result: ok. 3 passed; 0 failed; 0 ignored
+```
+
+**What just happened?** The audit tool:
+1. Connected to the relay on port 7000
+2. Checked NIP-01 compliance (event submission, retrieval)
+3. Tested isolation between test runs
+4. Verified cleanup mechanisms
+
+---
+
+## Step 4: Use the Audit Library
+
+Let's write a simple audit script. Create a new file:
+
+```bash
+# From grasp-audit directory
+cat > examples/my_audit.rs << 'EOF'
+use grasp_audit::prelude::*;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Create an audit client
+    let client = AuditClient::new("ws://localhost:7000").await?;
+    
+    println!("✅ Connected to relay");
+    
+    // Test basic event submission
+    let test_event = client.create_test_event("Hello GRASP!").await?;
+    println!("✅ Created test event: {}", test_event.id);
+    
+    // Verify we can retrieve it
+    let retrieved = client.get_event(&test_event.id).await?;
+    println!("✅ Retrieved event successfully");
+    
+    println!("\n🎉 Basic audit passed!");
+    
+    Ok(())
+}
+EOF
+```
+
+**Note:** This is a simplified example. The actual audit tool has more sophisticated checks.
+
+---
+
+## Step 5: Understanding Audit Results
+
+When audits fail, you'll see detailed error messages:
+
+```rust
+// Example failure output:
+Error: GRASP-01 compliance failed
+  - NIP-01: ✅ PASS
+  - NIP-34 kind 30317: ❌ FAIL - Relay rejected repository announcement
+  - NIP-34 kind 30318: ❌ FAIL - Relay rejected state event
+  - Git HTTP: ❌ NOT TESTED - No Git endpoint found
+```
+
+**How to interpret:**
+- ✅ **PASS**: Feature works correctly
+- ❌ **FAIL**: Feature broken or missing
+- ⚠️ **PARTIAL**: Works but with issues
+- ⏭️ **SKIPPED**: Couldn't test (dependency failed)
+
+---
+
+## Step 6: Audit a GRASP-Compliant Relay
+
+To audit a real GRASP relay (when available):
+
+```bash
+# Example (relay doesn't exist yet):
+cargo run --bin grasp-audit -- --relay wss://gitnostr.com
+
+# Or use the library:
+let client = AuditClient::new("wss://gitnostr.com").await?;
+let results = client.run_full_audit().await?;
+println!("{}", results.summary());
+```
+
+**What this would check:**
+- Nostr relay functionality (NIP-01)
+- Git event acceptance (NIP-34)
+- Git HTTP endpoint availability
+- Push authorization logic
+- Multi-maintainer support
+
+---
+
+## Step 7: Automated Testing
+
+The audit tool is designed for CI/CD integration:
+
+```bash
+# Run all tests (unit + integration)
+cargo test --all
+
+# Run only integration tests
+cargo test --ignored
+
+# Generate coverage report
+cargo tarpaulin --ignored --out Html
+```
+
+**Use in CI:**
+```yaml
+# Example GitHub Actions
+- name: Run GRASP Compliance Tests
+  run: |
+    docker run -d -p 7000:7000 scsibug/nostr-rs-relay
+    cd grasp-audit
+    cargo test --ignored
+```
+
+---
+
+## What You've Accomplished
+
+Congratulations! You now:
+
+✅ Understand GRASP compliance requirements  
+✅ Can run the audit tool against a relay  
+✅ Know how to interpret audit results  
+✅ Can integrate audits into your workflow
+
+---
+
+## Next Steps
+
+### Learn more about testing:
+- Read [Compliance Testing How-To](../how-to/test-compliance.md)
+- Review [Test Strategy](../reference/test-strategy.md)
+
+### Understand the protocols:
+- Read [GRASP Protocol Reference](../reference/grasp-protocol.md)
+- Review [Git Protocol Reference](../reference/git-protocol.md)
+
+### Contribute to grasp-audit:
+- Check open issues
+- Add new compliance checks
+- Improve error messages
+
+---
+
+## Troubleshooting
+
+### "Connection refused" errors
+- Make sure the relay is running: `docker ps`
+- Check the port: `netstat -an | grep 7000`
+- Verify the URL: `ws://localhost:7000` (not `wss://`)
+
+### Tests timeout
+- Relay might be slow to start
+- Try running tests again after 5 seconds
+- Check Docker logs: `docker logs <container-id>`
+
+### "Event rejected" errors
+- Expected for non-GRASP relays
+- The relay might not support NIP-34
+- This is normal for the tutorial relay
+
+---
+
+## Deep Dive: How Audits Work
+
+The audit tool uses **isolated test environments**:
+
+```rust
+// Each test gets a unique identifier
+let isolation = IsolationContext::new("my-test");
+
+// Events are tagged with this identifier
+let event = isolation.create_event("test content").await?;
+
+// Cleanup removes only this test's events
+isolation.cleanup().await?;
+```
+
+**Why isolation matters:**
+- Tests don't interfere with each other
+- Can run tests in parallel
+- Easy cleanup (no leftover data)
+
+See [Test Strategy Reference](../reference/test-strategy.md) for details.
+
+---
+
+## Summary
+
+You've learned how to:
+- Run GRASP compliance audits
+- Interpret audit results
+- Use the audit library
+- Integrate audits into testing workflows

+# Tutorial: Getting Started with ngit-grasp
+
+**Purpose:** Learn the basics of ngit-grasp through hands-on setup  
+**Time:** 15-20 minutes  
+**Prerequisites:** Basic Git and command-line knowledge
+
+---
+
+## What You'll Learn
+
+By the end of this tutorial, you will:
+- ✅ Have a working ngit-grasp development environment
+- ✅ Understand the basic project structure
+- ✅ Run the test suite successfully
+- ✅ Know where to go next
+
+---
+
+## Step 1: Clone the Repository
+
+First, get the source code:
+
+```bash
+git clone https://gitworkshop.dev/ngit-grasp
+cd ngit-grasp
+```
+
+**What just happened?** You cloned the ngit-grasp repository from the GRASP-enabled Git server.
+
+---
+
+## Step 2: Set Up Nix Development Environment
+
+ngit-grasp uses Nix flakes for reproducible development environments.
+
+```bash
+# Enter the development environment
+nix develop
+
+# You should see a new shell with all dependencies available
+```
+
+**What just happened?** Nix read `flake.nix` and created a shell with:
+- Rust toolchain (cargo, rustc)
+- Git
+- All required system libraries
+
+**Tip:** If `nix develop` doesn't work, you might be using an old Nix version. See the [Nix Flakes How-To](../how-to/nix-flakes.md) for help.
+
+---
+
+## Step 3: Explore the Project Structure
+
+Take a look around:
+
+```bash
+# View the project structure
+ls -la
+
+# Key directories:
+# - src/          - Main ngit-grasp source code (coming soon)
+# - grasp-audit/  - Compliance testing tool (working)
+# - docs/         - Documentation (you are here!)
+```
+
+**What you're seeing:**
+- `grasp-audit/` is a **subproject** with its own Cargo workspace
+- Main ngit-grasp server implementation is planned but not yet started
+- Documentation uses Diátaxis framework (tutorials, how-to, reference, explanation)
+
+---
+
+## Step 4: Work with grasp-audit
+
+The compliance testing tool is the first working component. Let's try it:
+
+```bash
+# Navigate to grasp-audit
+cd grasp-audit
+
+# Enter its development environment
+nix develop
+
+# Build the project
+cargo build
+
+# Run unit tests
+cargo test
+```
+
+**What just happened?** 
+- `grasp-audit` has its own `flake.nix` for isolated dependencies
+- Unit tests run without external dependencies
+- Integration tests (marked `#[ignore]`) require a Nostr relay
+
+---
+
+## Step 5: Run Your First Audit (Optional)
+
+If you want to try the audit tool against a real relay:
+
+```bash
+# In a separate terminal, start a test relay:
+docker run --rm -p 7000:7000 scsibug/nostr-rs-relay
+
+# Back in grasp-audit directory:
+cargo test --ignored -- --test-threads=1
+```
+
+**What just happened?** Integration tests connected to the relay on port 7000 and verified GRASP compliance.
+
+**Note:** This step is optional. The relay must be running for these tests to pass.
+
+---
+
+## Step 6: Explore the Code
+
+Let's look at a simple example:
+
+```bash
+# From grasp-audit directory
+cat examples/simple_audit.rs
+```
+
+This shows how to use the `grasp-audit` library to check GRASP compliance.
+
+---
+
+## Step 7: Read the Documentation
+
+Now that you have a working setup, explore the documentation:
+
+```bash
+# From project root
+cd ..
+ls docs/
+```
+
+**Recommended reading order:**
+1. [Architecture Overview](../explanation/architecture.md) - Understand the design
+2. [Inline Authorization](../explanation/inline-authorization.md) - Key decision
+3. [Git Protocol Reference](../reference/git-protocol.md) - Technical details
+
+---
+
+## What You've Accomplished
+
+Congratulations! You now have:
+
+✅ A working Nix development environment  
+✅ Built and tested the grasp-audit tool  
+✅ Understanding of the project structure  
+✅ Knowledge of where to find more information
+
+---
+
+## Next Steps
+
+### If you want to contribute:
+1. Read [Architecture Overview](../explanation/architecture.md)
+2. Check open issues on the repository
+3. Review [Design Decisions](../explanation/decisions.md)
+
+### If you want to deploy:
+1. Follow [Deployment How-To](../how-to/deploy.md)
+2. Review [Configuration Reference](../reference/configuration.md)
+
+### If you want to understand GRASP:
+1. Read [GRASP Protocol Reference](../reference/grasp-protocol.md)
+2. Review [Comparison with ngit-relay](../explanation/comparison.md)
+
+### If you want to run compliance tests:
+1. Follow [Running Your First Audit Tutorial](first-audit.md)
+2. Review [Compliance Testing How-To](../how-to/test-compliance.md)
+
+---
+
+## Troubleshooting
+
+### "nix develop" doesn't work
+- You might need Nix with flakes enabled
+- See [Nix Flakes How-To](../how-to/nix-flakes.md)
+
+### Build errors in grasp-audit
+- Make sure you're in the `grasp-audit` directory
+- Run `nix develop` first
+- Check that you have network access (Cargo needs to download crates)
+
+### Tests fail
+- Unit tests should always pass
+- Integration tests (`--ignored`) require a relay on port 7000
+- Use `--test-threads=1` for integration tests
+
+---
+
+## Summary
+
+You've successfully set up ngit-grasp and learned:
+- How to use Nix flakes for development
+- The project structure (main server + grasp-audit tool)
+- How to build and test the code
+- Where to find documentation
+
+**Ready for more?** Try the [First Audit Tutorial](first-audit.md) next!

+# Work Directory
+
+**Purpose:** Temporary working documents during development sessions  
+**Lifecycle:** Created during session → Archived at session end  
+**Status:** `.gitignore`d - not committed to version control
+
+---
+
+## What Goes Here
+
+- Session summaries and notes
+- Status reports and visual summaries
+- Migration documentation (during migration)
+- Planning documents
+- Temporary analysis files
+
+**Rule:** Nothing in this directory should be permanent. Archive or delete at session end.
+
+---
+
+## Workflow
+
+### During Session
+```bash
+# Create working docs here
+echo "Session notes..." > work/session-notes.md
+echo "Status..." > work/status.md
+```
+
+### End of Session
+```bash
+# Archive important docs
+mv work/session-notes.md docs/archive/2025-11-04-session-notes.md
+
+# Delete obsolete docs
+rm work/status.md
+
+# Clean up
+rm -rf work/*
+```
+
+---
+
+## .gitignore
+
+This directory is ignored by git (except this README):
+
+```
+work/*
+!work/README.md
+```
+
+**Why:** Working documents are session-specific and shouldn't clutter the repository.
+
+---
+
+## Best Practices
+
+**DO:**
+- ✅ Use for temporary session work
+- ✅ Use descriptive names
+- ✅ Archive valuable content before deleting
+- ✅ Clean up at session end
+
+**DON'T:**
+- ❌ Put permanent documentation here
+- ❌ Reference work/ docs from permanent docs
+- ❌ Commit work/ contents to git
+- ❌ Let it accumulate files
+
+---
+
+## Alternative: Session-Specific Directories
+
+For complex sessions, create dated subdirectories:
+
+```bash
+work/
+├── 2025-11-04-diataxis-migration/
+│   ├── notes.md
+│   ├── checklist.md
+│   └── visual-summary.txt
+└── 2025-11-05-feature-x/
+    └── plan.md
+```
+
+Archive the entire directory when done:
+```bash
+tar czf docs/archive/2025-11-04-diataxis-migration.tar.gz work/2025-11-04-diataxis-migration/
+rm -rf work/2025-11-04-diataxis-migration/
