+"""Krystie Gate — static check stage of the CI gate.
+
+Runs inside the Gitea Actions runner. Inspects all commits that were just
+pushed to a krystie-wip/* branch and rejects if any violates the gate rules.
+
+Decision per commit:
+  * If signed by Krystie's GPG key (fingerprint DCF2579968107984), apply the
+    full per-repo gate.
+  * If signed by a different key OR unsigned, allow (Sami's authority).
+
+Per-repo enforcement:
+  * triangles_v5      : red-list (consensus paths) + test-first + no-clearnet
+  * triangles-explorer, triangles-api, tridock-web-wallet, sami-chat, tri-pi:
+                        test-first only
+  * homebrew-triangles: formula syntax check only
+
+Outputs:
+  * On reject, prints REJECTED lines to stderr and exits 1.
+  * On accept, sets `is_krystie_commit` GH-actions output to true/false.

-# Triangles Codebase Cleanup Notes
-
-## Overview
-Systematic code quality improvements for the Triangles cryptocurrency codebase (v5.3.4+).
-
-**Goal:** Improve maintainability without changing behavior or breaking consensus.
-
-## Inventory
-
-### TODOs/FIXMEs Found (38 total)
-
-#### High Priority (Affects Safety/Correctness)
-- `rpcmining.cpp:263` - **Thread safety issue** in mapNewBlock (static variable, no mutex)
-- `walletmodel.cpp:249` - **Potential collision** in balance calculation
-- `smessage.cpp:863, 2219, 2373` - **File size limit** (files must be split if >2GB)
-
-#### Medium Priority (Encapsulation/Security)
-- `protocol.h:50, 100, 132` - Public members should be private (3 locations)
-- `wallet.h:378` - nOrderPos calculation should move elsewhere
-- `wallet.cpp:733, 1732` - Change output handling needs improvement
-- `rpcwallet.cpp:1474, 1513, 1569` - SecureString operator= missing (forced .c_str())
-
-#### Low Priority (Nice-to-Have)
-- `util.cpp:1322` - Disabled feature needs verification
-- `tor/tor_embedded.cpp:209` - Tor 0.4.9+ shutdown API upgrade
-- `init.cpp:442` - Remaining sanity checks (see Bitcoin issue #4081)
-- `rpcmining.cpp:232` - DRM comment (unclear what it means)
-- `smessage.cpp:*` - Various improvements (hash inclusion, thread safety, defaults)
-- `qt/*` - UI improvements (decrypt not supported, message filtering, OSX startup)
-
-#### External/Third-Party (Don't Touch)
-- `leveldb/*` - LevelDB library TODOs (upstream issues)
-
-## Code Quality Issues
-
-### Using namespace std (37 files)
-All in .cpp files - **this is fine for .cpp**, problematic only in headers.
-No headers have this issue, so **no action needed**.
-
-### Printf/Cout Usage (56 files)
-Most cryptocurrency code uses printf for early init/error handling before logging is available.
-**Review needed:** Check if these are legitimate early-init cases or should use LogPrintf.
-
-## Cleanup Plan (Safest → Riskiest)
-
-### Phase 1: Documentation & Comments ✅ SAFE
-1. Document all TODOs with context (why deferred, what's needed)
-2. Add function-level comments for complex logic
-3. Improve inline comments for clarity
-
-### Phase 2: Low-Risk Code Quality 🟨 MEDIUM RISK
-4. Fix compiler warnings (-Wall -Wextra)
-5. Add const correctness where missing
-6. Remove commented-out dead code
-7. Standardize code formatting (if inconsistent)
-
-### Phase 3: Functional Improvements 🟥 HIGH RISK (Skip for now)
-8. Fix thread safety issue in rpcmining.cpp (requires testing)
-9. Improve protocol.h encapsulation (may affect other code)
-10. Address >2GB file handling in smessage.cpp
-
-## Decisions
-
-### What NOT to Change
-- **Consensus code** - main.cpp (validation), kernel.cpp (PoS), miner.cpp (staking)
-- **Serialization** - Any READWRITE, serialize/deserialize code
-- **Protocol constants** - Network message types, version numbers
-- **Third-party code** - leveldb/, tor/, sph_types.h, xxhash/, lz4/
-
-### What's Safe to Change
-- Comments and documentation
-- Variable names (in non-consensus code)
-- Code organization (splitting large functions)
-- Logging statements
-- UI code (qt/)
-- RPC interface (as long as API contract preserved)
-
-## Initial Cleanup (2026-03-22)
-
-### Actions Taken
-1. Created this documentation file
-2. Created cleanup/desloppify branch
-3. Inventoried all TODOs/FIXMEs
-
-### Next Steps
-1. Add documentation comments to TODO items
-2. Review printf/cout usage patterns
-3. Check for compiler warnings
-4. Consider low-risk improvements
-
-## Notes
-- This is a Bitcoin-derived codebase, so many patterns follow Bitcoin Core conventions
-- Recent v5.3.x work already modernized to C++17 and removed Boost - good foundation
-- Code is generally well-structured; main improvements are documentation and minor cleanup

-# 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.

-# Embedded Tor Integration Guide for Triangles
-
-This guide explains how to compile Tor as a static library (`libtor.a`) and link
-it directly into the Triangles wallet binary so that every node automatically
-runs a Tor hidden service without needing an external Tor installation.
-
-## Architecture Overview
-
-```
-trianglesd / triangles-qt
-  ├── tor_embedded.cpp    ← calls tor_run_main() in a background thread
-  ├── tor_process.cpp     ← fallback: launches external tor binary (already works)
-  ├── onion_v3.cpp        ← V3 onion address generation / SOCKS5 proxy logic
-  └── libtor.a            ← aggregate static Tor library (built from official source)
-```
-
-When compiled with `ENABLE_TOR_EMBEDDED`, the wallet calls `tor_run_main()` from
-`tor_api.h` on a dedicated thread. This gives the wallet a SOCKS5 proxy on
-`127.0.0.1:19099` and a V3 hidden service on port 24112 (the P2P port).
-
-When compiled **without** the flag, `tor_embedded.cpp` falls back to the external
-`tor_process.cpp` which searches for and launches a system `tor` binary.
-
-## Step 1: Add Tor as a Git Submodule
-
-```bash
-cd /path/to/triangles
-git submodule add https://gitlab.torproject.org/tpo/core/tor.git src/tor/tor-src
-cd src/tor/tor-src
-git checkout release-0.4.9   # latest stable branch as of 2026
-```
-
-This puts the full Tor source at `src/tor/tor-src/`.
-Current imported checkout in this repo: `release-0.4.9` at commit `1442ca4`.
-There is also a helper build script at `src/tor/build-libtor.sh`.
-
-## Step 2: Build libtor.a
-
-Tor uses autotools. Build it as a static library:
-
-```bash
-cd src/tor/tor-src
-
-# Install Tor build dependencies
-sudo apt install autoconf automake libtool pkg-config \
-    libssl-dev libevent-dev zlib1g-dev
-
-# Generate configure script
-./autogen.sh
-
-# Configure for static library build (disable unneeded modules)
-./configure \
-    --enable-static-tor \
-    --disable-module-relay \
-    --disable-module-dirauth \
-    --disable-asciidoc \
-    --disable-manpage \
-    --disable-html-manual \
-    --disable-unittests \
-    --disable-tool-name-check \
-    --with-openssl-dir=/usr \
-    --with-libevent-dir=/usr \
-    --with-zlib-dir=/usr \
-    --prefix=/usr/local
-
-make -j$(nproc)
-```
-
-Or from the repo root:
-```bash
-./src/tor/build-libtor.sh
-```
-
-After building, the static libraries are in `src/tor/tor-src/`:
-- `libtor.a`
-- `src/lib/libtor-*.a` (multiple component libs)
-
-The header `src/feature/api/tor_api.h` provides the public C API:
-```c
-tor_main_configuration_t *tor_main_configuration_new(void);
-int tor_main_configuration_set_command_line(tor_main_configuration_t *cfg,
-                                             int argc, char *argv[]);
-int tor_run_main(const tor_main_configuration_t *);
-void tor_main_configuration_free(tor_main_configuration_t *);
-```
-
-## Step 3: Build Triangles with Embedded Tor
-
-### Linux (makefile.unix)
-
-```bash
-cd src
-
-# Point to Tor's built libraries and headers
-make -f makefile.unix \
-    USE_TOR_EMBEDDED=1
-```
-
-You may need to adjust the `-l` flags in the makefile depending on the exact
-library names Tor produces. Check `src/tor/tor-src/` after building:
-
-```bash
-find tor/tor-src -name '*.a' | sort
-```
-
-On the imported `release-0.4.9` checkout in this repo, the simplest working
-link path is the aggregate `libtor.a` plus the normal dependency libraries.
-
-### Windows (triangles-qt.pro)
-
-Add to `triangles-qt.pro`:
-```qmake
-qmake "USE_TOR_EMBEDDED=1" \
-      "TOR_SOURCE_ROOT=src/tor/tor-src"
-```
-
-Both build systems now default to:
-- source root: `src/tor/tor-src`
-- include path: `src/tor/tor-src/src/feature/api`
-- library path: `src/tor/tor-src`
-- embedded Tor library: `-ltor`
-
-On Windows, the imported Tor `0.4.9.5` build also needed:
-- `-llzma`
-- `-lzstd`
-- `-liphlpapi`
-- `-lshlwapi` (already linked by Triangles)
-
-## Step 4: Wire into init.cpp
-
-The global hooks `StartEmbeddedTor()` and `StopEmbeddedTor()` need to be called
-from `init.cpp`. Add these calls:
-
-### In AppInit2() (after network init, before starting node):
-```cpp
-#include "tor/tor_embedded.h"
-
-// Near the end of AppInit2, after network initialization:
-if (!StartEmbeddedTor()) {
-    printf("WARNING: Embedded Tor failed to start. .onion connectivity unavailable.\n");
-    // Non-fatal: wallet works without Tor, just no .onion
-}
-```
-
-### In Shutdown():
-```cpp
-StopEmbeddedTor();
-```
-
-## Step 5: Configure SOCKS Proxy for Outbound Connections
-
-After Tor starts, the wallet needs to route `.onion` connections through the
-SOCKS5 proxy. In `net.cpp`, after Tor is initialized:
-
-```cpp
-// If embedded Tor is running, use its SOCKS proxy for .onion addresses
-CTorEmbedded* tor = CTorEmbedded::GetInstance();
-if (tor->IsRunning()) {
-    // Set proxy for .onion connections
-    proxyType addrProxy(CService("127.0.0.1", tor->GetSocksPort()), 5);
-    SetNameProxy(addrProxy);
-}
-```
-
-## Runtime Flags
-
-The embedded Tor respects these command-line flags:
-
-| Flag | Default | Description |
-|------|---------|-------------|
-| `-notor` | false | Disable Tor entirely |
-| `-torsocks=PORT` | 19099 | SOCKS5 proxy port |
-| `-torhsport=PORT` | 24112 | Hidden service virtual port |
-
-## File Layout After Integration
-

-
-## Reference: How VERGE (XVG) Does It
-
-VERGE uses the same pattern. Their implementation is at:
-- `src/torcontroller.cpp` (~100 lines)
-- They use `tor_main()` (older API, pre-0.4.5)
-- Git submodule at `src/tor/` pointing to `release-0.4.8` branch
-- Build Tor as part of their `depends/` system
-
-Key difference: modern Tor (0.4.5+) uses `tor_run_main()` with a configuration
-object instead of raw `tor_main(int argc, char** argv)`.
-
-## Troubleshooting
-
-**Tor fails to bootstrap**: Check firewall rules. Tor needs outbound TCP to the
-Tor network (ports 80, 443, 9001, 9030).
-
-**Link errors with libtor**: Prefer the aggregate `libtor.a` from the top level
-of the Tor build tree. On the imported Windows/MSYS2 build in this repo, the
-minimal verified link set was:
-```
--ltor -levent -lssl -lcrypto -lz -llzma -lzstd -lws2_32 -liphlpapi -lshlwapi
-```
-
-**OpenSSL version mismatch**: Both Tor and Triangles must link against the same
-OpenSSL version (3.x). If Tor was built against a different OpenSSL, rebuild it
-with the same `--with-openssl-dir`.

-# TODO/FIXME Documentation
-
-Detailed context for each TODO/FIXME in the codebase.
-
-## Critical (Needs Attention)
-
-### src/rpcmining.cpp:263 - Thread Safety Issue
-```cpp
-static mapNewBlock_t mapNewBlock;    // FIXME: thread safety
-```
-**Issue:** Static variable accessed by multiple RPC threads without mutex protection.
-**Impact:** Potential race condition in getwork RPC (used for mining).
-**Status:** Low priority - PoW mining ended at block 9000, this code path rarely used.
-**Fix:** Add std::mutex and lock_guard if getwork usage increases.
-
-### src/qt/walletmodel.cpp:249 - Collision Risk
-```cpp
-if((total + nFeeRequired) > nBalance) // FIXME: could cause collisions in the future
-```
-**Issue:** Balance check may have edge case causing transaction collisions.
-**Context:** In createTransaction fee calculation loop.
-**Status:** Needs investigation - unclear what "collisions" means here.
-**Fix:** Review Bitcoin Core's current implementation of this logic.
-
-### src/smessage.cpp - File Size Limits
-```cpp
-// Lines 863, 2219, 2373: "TODO files must be split if > 2GB"
-```
-**Issue:** Secure message storage files not split when exceeding 2GB.
-**Impact:** May fail on 32-bit systems or with large message volumes.
-**Status:** Low priority - unlikely to reach 2GB in practice.
-**Fix:** Implement file rotation when approaching 2GB limit.
-
-## Medium Priority (Encapsulation/API)
-
-### src/protocol.h - Make Members Private
-```cpp
-// Lines 50, 100, 132: "TODO: make private (improves encapsulation)"
-```
-**Issue:** CAddress, CInv, CMessageHeader have public data members.
-**Impact:** Poor encapsulation, harder to maintain invariants.
-**Status:** Deferred - would require extensive refactoring.
-**Fix:** Add getter/setter methods, make members private, update all call sites.
-
-### src/wallet.h:378 - nOrderPos Calculation
-```cpp
-nOrderPos = -1; // TODO: calculate elsewhere
-```
-**Issue:** Transaction ordering position calculated in constructor.
-**Impact:** Minor - works but not ideal separation of concerns.
-**Status:** Deferred - no functional issue.
-**Fix:** Move calculation to WalletDB when transaction is added.
-
-### src/rpcwallet.cpp / src/qt/askpassphrasedialog.cpp - SecureString Conversion
-**Issue:** Password-handling paths were converting through `.c_str()` because `SecureString`
-did not have a convenient conversion helper from `std::string`.
-**Impact:** Unnecessary C-string shims in sensitive code paths.
-**Status:** Resolved.
-**Fix:** Added `MakeSecureString(const std::string&)` in `src/allocators.h` and updated
-the wallet RPC and passphrase dialog call sites to use it directly.
-
-## Low Priority (Nice-to-Have)
-
-### src/util.cpp:1322 - Disabled Feature
-```cpp
-// TODO: This is currently disabled because it needs to be verified to work
-```
-**Context:** File descriptor management code.
-**Status:** Intentionally disabled pending verification.
-**Fix:** Test thoroughly, then enable if needed.
-
-### src/tor/tor_embedded.cpp:209 - Tor Shutdown API
-```cpp
-// TODO: Tor 0.4.9+ may add tor_api_shutdown(), use it when available
-```
-**Context:** Embedded Tor cleanup.
-**Status:** Waiting for upstream Tor API.
-**Fix:** Check Tor 0.4.9+ releases for new API, integrate when stable.
-
-### src/init.cpp:442 - Sanity Checks
-```cpp
-// TODO: remaining sanity checks, see #4081
-```
-**Context:** Bitcoin Core issue #4081 - additional startup sanity checks.
-**Status:** Deferred - core checks already in place.
-**Fix:** Review Bitcoin Core's current sanity check implementation.
-
-### src/rpcmining.cpp:232 - DRM Comment
-```cpp
-CDataStream(coinbase, SER_NETWORK, PROTOCOL_VERSION) >> pblock->vtx[0]; // FIXME - DRM!
-```
-**Issue:** Unclear what "DRM" means here - likely "Data Race Maybe"?
-**Status:** Needs clarification from original author.
-**Fix:** Investigate if there's an actual issue, otherwise remove comment.
-
-## Deferred (External/Low Impact)
-
-### LevelDB TODOs (src/leveldb/*)
-**Status:** Upstream LevelDB issues - don't modify embedded library.
-**Action:** None - track upstream LevelDB project.
-
-### Qt TODOs (src/qt/*)
-**Status:** UI improvements, not critical.
-**Action:** Track as nice-to-have enhancements.
-
-### Secure Message TODOs (src/smessage.cpp)
-Multiple minor improvements suggested:
-- Include hash in certain operations
-- Improve thread shutdown
-- Set default recv/recvAnon behavior
-- Update outbox after PoW completes
-
-**Status:** Non-critical enhancements.
-**Action:** Consider for future encrypted messaging upgrades.
-
-## Summary
-
-**Critical:** 3 items (thread safety, balance collision, file limits)
-**Medium:** 6 items (encapsulation, SecureString)
-**Low:** 5 items (disabled features, upstream APIs)
-**Deferred:** ~24 items (external libs, minor enhancements)
-
-**Recommendation:** Focus on documenting critical items in code comments, defer fixes until specific issues arise.

+# Triangles Tor-Native Architecture
+
+**Date:** 2026-03-26  
+**Status:** ✅ IMPLEMENTED & WORKING
+
+---
+
+## What This Is
+
+Triangles is now a **Tor-native proof-of-stake network** where:
+
+- **Every node = Tor hidden service** (.onion address)
+- **All P2P traffic = routed through Tor** (mandatory SOCKS5)
+- **Zero clearnet connections** (IPv4/IPv6 disabled)
+- **Network-layer anonymity = enforced by design**
+
+This is not "Tor support" or "Tor optional" — this is a network that **cannot exist outside Tor**.
+
+---
+
+## Architecture Enforcements
+
+### 1. Mandatory Tor Routing (`init.cpp`)
+
+```cpp
+// Force all network types through Tor SOCKS proxy
+SetProxy(NET_IPV4, torProxyAddr, 5);
+SetProxy(NET_IPV6, torProxyAddr, 5);
+SetProxy(NET_TOR, torProxyAddr, 5);
+SetNameProxy(torProxyAddr, 5);
+
+// Disable clearnet reachability
+SetReachable(NET_IPV4, false);
+SetReachable(NET_IPV6, false);
+SetReachable(NET_TOR, true);
+```
+
+**Result:** No traffic can leave except through Tor.
+
+---
+
+### 2. .onion-Only Peer Filter (`net.cpp`)
+
+```cpp
+// Reject all non-.onion addresses at connection time
+std::string addrStr = pszDest ? std::string(pszDest) : addrConnect.ToStringIP();
+if (addrStr.find(".onion") == std::string::npos) {
+    printf("ConnectNode(): REJECTED non-onion address: %s\n", addrStr.c_str());
+    return NULL;
+}
+```
+
+**Result:** Peers with IP addresses are refused immediately.
+
+---
+
+### 3. Onion-Only DNS Seeds (`net.cpp`)
+
+```cpp
+static const char* strDNSSeed[] = {
+    "7nu7ibx7cnbjy2dohuc2rhzjowruuoq6tyaeuhivepg5ougxrye656yd.onion",
+    "byo5cmef72jtrotvo4lbadlqsciijcws2v5g7c6ligh4pcazolouvvqd.onion",
+};
+```
+
+**Result:** Bootstrap uses .onion seeds only (no DNS, no clearnet fallback).
+
+---
+
+### 4. UPnP Disabled (`init.cpp`)
+
+```cpp
+#ifdef USE_UPNP
+fUseUPnP = false;
+#endif
+```
+
+**Result:** No port forwarding attempts (not needed for hidden services).
+
+---
+
+### 5. Embedded Tor Requirement (`init.cpp`)
+
+```cpp
+if (torStarted) {
+    printf("TOR-NATIVE MODE: All network traffic forced through Tor\n");
+} else {
+    return InitError(_("Tor failed to start. Triangles requires Tor to operate."));
+}
+```
+
+**Result:** If Tor doesn't start, the daemon refuses to run.
+
+---
+
+## What This Achieves
+
+### Privacy Guarantees
+
+| Attack Vector | Protection |
+|---------------|------------|
+| IP address exposure | ✅ Impossible - all traffic through Tor |
+| ISP/network monitoring | ✅ Tor circuits + encryption |
+| Node location tracking | ✅ Hidden service identity only |
+| Clearnet metadata leaks | ✅ Clearnet completely disabled |
+| Peer correlation | ✅ .onion addresses unlinkable to IPs |
+
+---
+
+### Network Properties
+
+- **Identity = .onion address** (56-character Ed25519 v3)
+- **No DNS required** (onion resolution via Tor)
+- **No port forwarding** (hidden services are inbound-accessible)
+- **Global connectivity** (Tor handles NAT traversal)
+- **Censorship resistance** (Tor bridges available)
+
+---
+
+## Testing Verification
+
+### Expected Behavior
+
+1. **Startup:**
+   ```
+   Embedded Tor starting (SOCKS 19099, HS port 24111)...
+   TOR-NATIVE MODE: All network traffic forced through Tor
+     Clearnet disabled - .onion addresses only
+   Tor hidden service: [56-char-onion].onion
+   ```
+
+2. **Connection attempts:**
+   ```
+   SOCKS5 connecting [onion-address].onion
+   trying connection [onion-address].onion:24111
+   ```
+
+3. **No clearnet peers:**
+   ```
+   # This should NOT appear:
+   trying connection 192.168.x.x  ❌
+   trying connection 8.8.8.8      ❌
+   ```
+
+### Test Command

+
+## Positioning Statement
+
+**Before:**
+> Triangles is a cryptocurrency with Tor support
+
+**After:**
+> **Triangles is a Tor-native proof-of-stake network where all nodes operate as hidden services and all communication is routed through the Tor network, eliminating IP-level identity exposure.**
+
+---
+
+## Implementation Commits
+
+1. `85fe0d0` - Add Tor 0.4.9 as submodule
+2. `de1d4ec` - Fix makefile link order for libtor
+3. `36ade21` - Document embedded Tor success
+4. `fe5a4cb` - **Enforce Tor-native architecture**
+
+---
+
+## Trade-offs
+
+### Pros ✅
+- **Network-layer anonymity** (not optional)
+- **Censorship resistance** (Tor bridges)
+- **No port forwarding** needed
+- **Global connectivity** (NAT traversal via Tor)
+- **Real privacy differentiation** (not marketing)
+
+### Cons ⚠️
+- **Latency** (~300-500ms circuit build time)
+- **Bootstrap dependency** (requires Tor network to be accessible)
+- **Bandwidth** (Tor circuits add overhead)
+- **Seed node requirement** (must run .onion seeds)
+
+---
+
+## Future Work
+
+### Phase 2: Tor Control Port Integration
+
+Currently: Tor runs embedded but without control port management.
+
+**Next:**
+- Connect to Tor control port (127.0.0.1:9051)
+- Use `ADD_ONION` to create hidden service programmatically
+- Persist onion identity across restarts
+- Advertise .onion to network
+
+### Phase 3: End-to-End Encrypted Messaging
+
+Tor provides hop-by-hop encryption. For secure messaging:
+
+- Add E2EE layer on top of Tor
+- Use wallet keys for identity
+- Implement forward secrecy (Double Ratchet)
+
+### Phase 4: Seed Node Infrastructure
+
+- Deploy at least 3 stable .onion seed nodes
+- Consider using `HiddenServiceNonAnonymousMode` for seeds (faster, acceptable for public seeds)
+- Monitor seed health
+
+---
+
+## Security Considerations
+
+### What Tor Provides
+
+- **Circuit-level encryption** (3 hops)
+- **IP address hiding** (exit node sees destination, not origin)
+- **Hidden service anonymity** (rendezvous point protocol)
+
+### What Tor Does NOT Provide
+
+- **End-to-end encryption** (add separately for messaging)
+- **Traffic analysis immunity** (sophisticated adversaries can correlate)
+- **Perfect forward secrecy** (depends on implementation)
+
+### Threat Model
+
+**Protected against:**
+- ISP surveillance
+- Network-level attackers
+- Peer location tracking
+- Passive metadata collection
+
+**NOT protected against:**
+- Global passive adversary (NSA-level)
+- Timing correlation attacks (requires significant resources)
+- Application-level leaks (use Tor Browser principles)
+

+
+## Comparison to Other Projects
+
+| Project | Tor Integration | Enforcement |
+|---------|----------------|-------------|
+| **Triangles** | Embedded, mandatory | ✅ Enforced |
+| Bitcoin | Optional (via `-onlynet=onion`) | ❌ Optional |
+| Monero | Optional (via `--proxy`) | ❌ Optional |
+| Zcash | Optional | ❌ Optional |
+| Verge (XVG) | Embedded | ⚠️ Mixed mode |
+
+**Key difference:** Triangles cannot operate without Tor. The network architecture requires it.
+
+---
+
+## Documentation Updates Needed
+
+1. **README.md** - Update project description
+2. **Build docs** - Add Tor dependency requirements
+3. **FAQ** - Explain why Tor is mandatory
+4. **Whitepaper** - Document privacy architecture
+
+---
+
+## Conclusion
+
+Triangles is no longer "a coin with Tor support" — it's a **Tor-native network**.
+
+This architectural decision makes privacy a fundamental property, not a feature. Clearnet connectivity isn't just discouraged — it's **architecturally impossible**.
+
+For users who value network-layer anonymity, Triangles is now the only cryptocurrency where every single node is guaranteed to be a Tor hidden service.
+

+
+**Implementation:** Complete ✅  
+**Testing:** Verified ✅  
+**Ready for:** Mainnet deployment

+# Chain DB benchmark harness
+
+Measures `FastImportBlockFile()` speed under each chain-DB backend
+(LevelDB vs RocksDB) using a user-supplied `blk0001.dat` block stream.
+
+## Prerequisites
+
+- A `trianglesd` binary (RocksDB is now a hard build dep, both backends are
+  always available):
+  ```
+  cmake -B build -G Ninja \
+      -DCMAKE_BUILD_TYPE=Release \
+      -DBUILD_QT=OFF \
+      -DBUILD_DAEMON=ON
+  cmake --build build
+  ```
+- An `blk0001.dat` file (old-style block stream). If you have a synced
+  node, copy `~/.triangles/blk0001.dat` (Linux) or `%APPDATA%\triangles\blk0001.dat` (Windows).
+- Free disk space: ~3× the size of `blk0001.dat` per backend run
+  (raw blocks + chain DB index + working space).
+
+## Usage
+
+```bash
+contrib/bench/bench-chaindb.sh \
+  --binary=$(pwd)/build/bin/trianglesd \
+  --bootstrap=/path/to/blk0001.dat
+```
+
+Runs each backend in turn, appends a CSV row to `./bench-results.csv`,
+and prints a summary to stdout. Default `--dbcache=2048` (MB).
+
+### Options
+
+| Flag | Default | Notes |
+| --- | --- | --- |
+| `--binary=PATH` | (required) | Path to `trianglesd` |
+| `--bootstrap=PATH` | (required) | Path to `blk0001.dat` |
+| `--backends=LIST` | `leveldb,rocksdb` | Comma-separated subset |
+| `--workdir=DIR` | `/tmp/triangles-bench-XXXXXX` | Per-backend datadirs go here |
+| `--dbcache=MB` | `2048` | Chain DB cache size |
+| `--results-csv=FILE` | `./bench-results.csv` | Appended to |
+| `--keep-datadirs` | off | Preserve datadirs after run for inspection |
+| `--rpc-port=BASE` | `19112` | Each backend uses `BASE+offset` |
+
+## What it measures
+
+| Column | Source |
+| --- | --- |
+| `wall_ms` | The daemon's own log line: `FastImportBlockFile: indexed N blocks in Mms` |
+| `peak_rss_kb` | `ps -o rss=` sampled once per second |
+| `datadir_bytes` | `du -sb` of the working datadir (includes `blk0001.dat`) |
+| `blocks_indexed` | Parsed from the same log line |
+
+## What it does not measure
+
+- Network IBD (peer fetch, header sync) — this is pure DB ingest.
+- UTXO snapshot load — `LoadSnapshot` is currently rocksdb-guarded
+  (see `src/utxosnapshot.cpp`); will be unblocked when LevelDB is retired.
+- Reorg cost — separate test, not yet implemented.
+- Disk I/O bytes (read/written) — could be added with `iostat` integration.
+
+## Interpreting results
+
+A meaningful comparison requires both rows to have run on the same machine
+with the same `blk0001.dat`. The `host` column makes mixing runs across
+machines visible in the CSV.
+
+Backend-relevant size comparisons should subtract `bootstrap_size_bytes`
+from `datadir_bytes` to isolate the chain DB tree.
+
+## One-liners
+
+```bash
+# LevelDB only
+./bench-chaindb.sh --binary=... --bootstrap=... --backends=leveldb
+
+# Compare 2GB vs 4GB cache on RocksDB
+./bench-chaindb.sh --binary=... --bootstrap=... --backends=rocksdb --dbcache=2048
+./bench-chaindb.sh --binary=... --bootstrap=... --backends=rocksdb --dbcache=4096
+
+# Keep the datadirs for poking around afterwards
+./bench-chaindb.sh --binary=... --bootstrap=... --keep-datadirs
