Derive release VERSION from clientversion.h instead of hardcoding

Build jobs extract MAJOR.MINOR.REVISION from src/clientversion.h.
Release job extracts from the git tag name. No more forgetting to
update the workflow when bumping versions.

+# Triangles Cleanup Strategy - Safe Improvements
+
+**Branch:** `cleanup/safe-improvements`  
+**Goal:** Improve code quality without touching consensus-critical code
+
+## ✅ SAFE TO FIX
+
+### 1. Compiler Warnings (Non-Consensus)
+- **C++11 literal-suffix warnings** - Add spaces between literals and suffixes
+- **Unused variables/functions** - Remove dead code (verify not consensus-critical first)
+- **Deprecated-copy warnings** - Fix CScript assignment operator if safe
+
+### 2. Code Style Improvements
+- Remove `using namespace std` from headers (keep in .cpp files)
+- Standardize logging patterns
+- Improve code comments (remove unclear/misleading ones)
+- Add context to TODOs/FIXMEs
+
+### 3. Documentation
+- Add inline comments for thread safety concerns
+- Document collision vulnerabilities
+- Improve function/class documentation
+
+## ❌ DO NOT TOUCH
+
+### Consensus-Critical Code
+- **OpenSSL SHA256/RIPEMD160 usage** - Deprecated warnings OK, do not change
+- **BN_is_prime_ex** - Crypto library deprecation, leave as-is
+- **Hash algorithms** - Third-party libraries with warnings, consensus-critical
+- **Block validation logic** - Any code affecting block/transaction validation
+- **Merkle tree construction** - Core consensus
+- **Proof-of-Work/Proof-of-Stake** - Staking/mining algorithms
+
+### How to Identify Consensus Code
+- Files in `src/` related to: `main.cpp`, `main.h`, block validation, transaction validation
+- Anything in hash algorithm libraries
+- Cryptographic primitives
+- Network protocol message formats (version, serialization)
+
+## Incremental Testing Strategy
+
+1. **One warning category at a time**
+2. **Compile after each change**
+3. **Test basic functionality:**
+   - `trianglesd getinfo`
+   - `trianglesd getblockchaininfo`
+   - Verify block sync works
+4. **Commit incrementally** with clear messages
+
+## Warning Categories (From Build Output)
+
+```
+1. C++11 literal-suffix: ~20 instances (util.h, net.h, alert.cpp)
+2. OpenSSL deprecation: SHA256, RIPEMD160 (DO NOT FIX)
+3. BN_is_prime_ex: crypto library (DO NOT FIX)
+4. Deprecated-copy: CScript assignment (REVIEW CAREFULLY)
+5. Unused variables/functions: Various (SAFE IF NOT CONSENSUS)
+```
+
+## Branch History
+
+- Previous work: `cleanup/desloppify` (documentation improvements, merged to master)
+- This branch: Focus on safe compiler warnings and code quality
+
+## Verification Checklist
+
+Before pushing each commit:
+- [ ] Code compiles successfully
+- [ ] No new warnings introduced
+- [ ] trianglesd runs without errors
+- [ ] getinfo/getblockchaininfo work
+- [ ] No consensus-critical code touched
+
+---
+
+**Principle:** When in doubt, don't touch it. A clean codebase is worthless if the blockchain forks.

+# Triangles Bootstrap Server Setup - DNS2
+
+**For:** Krystie (@Krystie7777bot)
+**Server:** DNS2 (194.233.88.206) - Ubuntu
+**Date:** March 2026
+
+---
+
+## What This Server Does
+
+Your server is the **bootstrap server** for the Triangles network. When someone opens a fresh Triangles wallet:
+
+1. The wallet connects to `bootstrap.cryptographic-triangles.org` on **port 80**
+2. If that fails, it falls back to your IP directly: `194.233.88.206` on **port 80**
+3. It downloads `/filelist.txt` to see which blockchain files are available
+4. It downloads each file listed (mainly `blk0001.dat`, the entire blockchain)
+5. The user is now synced and ready to go
+
+Your IP is hardcoded in the wallet. If your server is down, new users can't bootstrap.
+
+Your server also runs the Triangles daemon so it doubles as a seed node on **port 24112**.
+
+---
+
+## Step 1: Install nginx
+
+```bash
+sudo apt update
+sudo apt install -y nginx curl
+```
+
+---
+
+## Step 2: Download the Daemon
+
+No building required. Download the pre-built Linux binary from GitHub:
+
+```bash
+cd /tmp
+curl -L -o trianglesd https://github.com/SamiAhmed7777/triangles_v5/releases/download/v5.3.7/Cryptographic-Triangles-v5.3.7-linux-x64-daemon
+chmod +x trianglesd
+sudo mv trianglesd /usr/local/bin/
+```
+
+Verify it works:
+
+```bash
+trianglesd --version
+```
+
+---
+
+## Step 3: Configure the Daemon
+
+```bash
+mkdir -p ~/.triangles
+
+RPC_PASS=$(openssl rand -hex 32)
+
+cat > ~/.triangles/triangles.conf << EOF
+port=24112
+listen=1
+maxconnections=125
+rpcport=19112
+rpcuser=trianglesrpc
+rpcpassword=$RPC_PASS
+rpcallowip=127.0.0.1
+server=1
+externalip=194.233.88.206
+addnode=74.208.167.19
+txindex=1
+daemon=1
+EOF
+```
+
+---
+
+## Step 4: Get the Blockchain Data
+
+OpenClaw will send you `blk0001.dat` (or a tarball containing it). Put it in `~/.triangles/`:
+
+```bash
+cd ~/.triangles
+# If you received a tarball:
+tar xzf /path/to/blockchain-data.tar.gz
+# Or if you received blk0001.dat directly:
+cp /path/to/blk0001.dat ~/.triangles/
+```
+
+After this step you should have:
+
+```
+~/.triangles/blk0001.dat
+~/.triangles/triangles.conf
+```
+
+Do NOT copy someone else's `wallet.dat` unless you intend to use that wallet.
+
+---
+
+## Step 5: Open Firewall Ports
+
+You need **two** ports open:
+
+```bash
+sudo ufw allow 80/tcp comment "Bootstrap HTTP server"
+sudo ufw allow 24112/tcp comment "Triangles P2P"
+sudo ufw enable
+sudo ufw status
+```
+
+Verify both show ALLOW:
+
+```
+80/tcp                     ALLOW       Anywhere        # Bootstrap HTTP server
+24112/tcp                  ALLOW       Anywhere        # Triangles P2P
+```
+
+Do NOT open 19112 (RPC).
+
+---
+
+## Step 6: Test the Daemon
+
+```bash
+trianglesd
+```
+
+Wait 10 seconds, then:
+
+```bash
+trianglesd getinfo
+```
+
+Look for:
+- `"blocks"` around 2,186,940 or higher
+- `"connections"` should become 1+ within a couple minutes
+
+If it works, stop it:
+
+```bash
+trianglesd stop
+```
+
+---
+
+## Step 7: Set Up the Daemon as a systemd Service
+
+```bash
+sudo tee /etc/systemd/system/trianglesd.service << 'EOF'
+[Unit]
+Description=Triangles Daemon
+After=network-online.target
+Wants=network-online.target
+
+[Service]
+Type=forking
+ExecStart=/usr/local/bin/trianglesd -daemon -datadir=/root/.triangles
+ExecStop=/usr/local/bin/trianglesd -datadir=/root/.triangles stop
+Restart=on-failure
+RestartSec=30
+TimeoutStopSec=120
+LimitNOFILE=65536
+
+[Install]
+WantedBy=multi-user.target
+EOF
+
+sudo systemctl daemon-reload
+sudo systemctl enable trianglesd
+sudo systemctl start trianglesd
+```
+
+If you're running as a non-root user, change `/root/.triangles` to `/home/youruser/.triangles`.
+
+Verify:
+
+```bash
+sudo systemctl status trianglesd
+trianglesd getinfo
+```
+
+---
+
+## Step 8: Set Up the Bootstrap File Server
+
+This is the main event.
+
+### 8a. Create the bootstrap directory and tarball
+
+```bash
+sudo mkdir -p /var/www/triangles-bootstrap
+
+# Create the compressed tarball from the blockchain data
+# Only blk0001.dat is needed - the wallet builds its own block index after download
+cd ~/.triangles
+tar czf /tmp/bootstrap.tar.gz blk0001.dat
+sudo mv /tmp/bootstrap.tar.gz /var/www/triangles-bootstrap/
+
+# Also create the legacy fallback files (for older wallet versions)
+sudo cp ~/.triangles/blk0001.dat /var/www/triangles-bootstrap/
+sudo tee /var/www/triangles-bootstrap/filelist.txt << 'EOF'
+blk0001.dat
+EOF
+
+sudo chown -R www-data:www-data /var/www/triangles-bootstrap
+```
+
+The wallet tries to download `bootstrap.tar.gz` first (compressed, faster). If that's missing, it falls back to downloading `blk0001.dat` directly using `filelist.txt`. After download, the wallet automatically imports the blocks and builds its own index.
+
+### 8b. Configure nginx
+
+```bash
+sudo rm -f /etc/nginx/sites-enabled/default
+
+sudo tee /etc/nginx/sites-available/triangles-bootstrap << 'EOF'
+server {
+    listen 80;
+    server_name bootstrap.cryptographic-triangles.org 194.233.88.206;
+
+    root /var/www/triangles-bootstrap;
+
+    location / {
+        try_files $uri =404;
+    }
+
+    send_timeout 600s;
+    keepalive_timeout 600s;
+}
+EOF
+
+sudo ln -sf /etc/nginx/sites-available/triangles-bootstrap /etc/nginx/sites-enabled/
+sudo nginx -t
+```
+
+That should print `syntax is ok` and `test is successful`. Then:
+
+```bash
+sudo systemctl enable nginx
+sudo systemctl restart nginx
+```
+
+### 8c. Verify it works
+
+```bash
+# Should print "blk0001.dat"
+curl http://localhost/filelist.txt
+
+# Should show HTTP 200 and a Content-Length
+curl -I http://localhost/blk0001.dat
+```
+
+### 8d. Test from outside
+
+Ask OpenClaw to test from another machine:
+
+```bash
+curl -I http://194.233.88.206/bootstrap.tar.gz
+curl http://194.233.88.206/filelist.txt
+```
+
+If both return HTTP 200, the bootstrap server is live.
+
+---
+
+## Step 9: Keeping Bootstrap Data Fresh
+
+Periodically rebuild the tarball from the latest blockchain data:
+
+```bash
+sudo systemctl stop trianglesd
+cd ~/.triangles
+tar czf /tmp/bootstrap.tar.gz blk0001.dat
+sudo mv /tmp/bootstrap.tar.gz /var/www/triangles-bootstrap/
+sudo cp ~/.triangles/blk0001.dat /var/www/triangles-bootstrap/
+sudo chown -R www-data:www-data /var/www/triangles-bootstrap
+sudo systemctl start trianglesd
+```
+
+Or set up a weekly cron job:
+
+```bash
+sudo tee /etc/cron.d/triangles-bootstrap-update << 'EOF'
+0 4 * * 0 root systemctl stop trianglesd && cd /root/.triangles && tar czf /tmp/bootstrap.tar.gz blk0001.dat && mv /tmp/bootstrap.tar.gz /var/www/triangles-bootstrap/ && cp /root/.triangles/blk0001.dat /var/www/triangles-bootstrap/ && chown -R www-data:www-data /var/www/triangles-bootstrap && systemctl start trianglesd
+EOF
+```
+
+---
+
+## Step 10: Tor Hidden Service (Optional)
+
+```bash
+sudo apt install -y tor
+```
+
+Add to `/etc/tor/torrc`:
+
+```
+HiddenServiceDir /var/lib/tor/triangles/
+HiddenServiceVersion 3
+HiddenServicePort 24112 127.0.0.1:24112
+```
+
+Then:
+
+```bash
+sudo systemctl restart tor
+sudo cat /var/lib/tor/triangles/hostname
+```
+
+Send the `.onion` address to OpenClaw, add `externalip=YOUR_ONION_ADDRESS.onion` to `triangles.conf`, and restart the daemon.
+
+---
+
+## Troubleshooting
+
+### Bootstrap server isn't working
+
+```bash
+sudo systemctl status nginx
+sudo ss -tlnp | grep :80
+ls -lh /var/www/triangles-bootstrap/
+curl http://localhost/filelist.txt
+sudo tail -30 /var/log/nginx/error.log
+```
+
+### Daemon has 0 connections
+
+```bash
+sudo ss -tlnp | grep 24112
+sudo ufw status
+trianglesd addnode 74.208.167.19 add
+```
+
+### Daemon won't start
+
+```bash
+tail -100 ~/.triangles/debug.log
+ps aux | grep trianglesd
+ls ~/.triangles/.lock
+```
+
+### "Error loading block database"
+
+```bash
+rm -rf ~/.triangles/txleveldb/
+sudo systemctl restart trianglesd
+```
+
+---
+
+## Quick Reference
+
+| What | Where / Value |
+|------|---------------|
+| **Bootstrap files** | `/var/www/triangles-bootstrap/` |
+| **bootstrap.tar.gz** | `/var/www/triangles-bootstrap/bootstrap.tar.gz` |
+| **filelist.txt** | `/var/www/triangles-bootstrap/filelist.txt` (legacy fallback) |
+| **blk0001.dat (web)** | `/var/www/triangles-bootstrap/blk0001.dat` (legacy fallback) |
+| **nginx config** | `/etc/nginx/sites-available/triangles-bootstrap` |
+| **nginx logs** | `/var/log/nginx/error.log` |
+| Daemon binary | `/usr/local/bin/trianglesd` |
+| Data directory | `~/.triangles/` |
+| Config file | `~/.triangles/triangles.conf` |
+| Debug log | `~/.triangles/debug.log` |
+| P2P port | **24112** (must be open) |
+| HTTP port | **80** (must be open) |
+| RPC port | 19112 (localhost only) |
+| Restart daemon | `sudo systemctl restart trianglesd` |
+| Restart nginx | `sudo systemctl restart nginx` |
+| Other seed node | 74.208.167.19 (DNS3-Sami) |
+| Contact | OpenClaw on Telegram |
+
+---
+
+## You're Done
+
+Once you've completed all the steps, your server is:
+
+1. **A seed node** — other wallets discover and connect to you on port 24112
+2. **A bootstrap server** — new wallets download the blockchain from you on port 80
+
+Send OpenClaw your `.onion` address (if you set up Tor) so it can be added to the wallet's onion seed list.
+
+To confirm everything is running:
+
+```bash
+# Daemon healthy?
+trianglesd getinfo
+
+# nginx serving files?
+curl -I http://localhost/bootstrap.tar.gz
+
+# Ports open externally?
+sudo ss -tlnp | grep -E ':(80|24112)\b'
+```
+
+If all three check out, you're live on the Triangles network.
