ci: produce portable Windows GUI wallet ZIP (was missing from release)

i2pHostname was cleared on Start() but never populated, so
GetI2PAddress() always returned empty and the Qt status bar never
showed the I2P address even when the router was running.

Now queries i2p::context.GetRouterInfo().GetIdentHash().ToBase32()
after the bootstrap loop completes (both early-success and timeout
paths). The address appears as <hash>.b32.i2p in the status bar.

+"""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 v5.9.24 — release → tridock rebuild dispatcher
+#
+# Purpose
+# -------
+# When a new Triangles release is published (e.g. v5.9.24) this workflow
+# fires a `repository_dispatch` event at the `samiahmed7777/tridock`
+# repository, which in turn triggers that repo's build-and-publish.yml to
+# bake the new Triangles binary into a fresh `samiahmed7777/tridock` image.
+#
+# Why this exists
+# ---------------
+# Before this workflow, tridock's Docker Hub `latest` tag only updated
+# when somebody manually edited the Dockerfile and pushed to master. That
+# made it easy to forget — DNS2 ran a 6-days-out-of-date image, and the
+# tridock-dev container ended up running v5.9.9 while DNS2 prod ran v5.9.23.
+# This workflow closes the gap: every Tri release auto-triggers a tridock
+# rebuild, and DNS2's self-hosted runner auto-deploys the result.
+#
+# Required GitHub Secrets / Vars on triangles_v5 repo
+# --------------------------------------------------
+# - TRIDOCK_DISPATCH_TOKEN: a GitHub PAT with `repo` scope on the
+#   samiahmed7777/tridock repository. NOT the same token as
+#   GITEA_SAMI_TOKEN / GITEA_DASHCADDY_TOKEN / DOCKERHUB_TOKEN.

+# I2P Embedded Architecture (Level 3)
+
+**Date:** 2026-06-27  
+**Status:** ✅ IMPLEMENTED & WORKING
+
+---
+
+## What This Is
+
+Triangles now runs **two embedded anonymity networks simultaneously**:
+
+1. **Tor** — Every node is a .onion hidden service (existing, unchanged)
+2. **I2P** — Every node is a .b32.i2p destination (new)
+
+Both routers run **in-process** as static libraries. No external dependencies, no separate daemons to install.
+
+### What I2P Adds Over Tor-Only
+
+| Property | Tor | I2P |
+|----------|-----|-----|
+| Routing | Onion (3-hop circuits) | Garlic (variable-hop tunnels) |
+| Directory | Centralized authorities | Distributed floodfills |
+| Service discovery | Hidden service descriptors | Network database (KadDHT) |
+| Designed for | Exit to clearnet | Peer-to-peer services |
+| Peer correlation resistance | Moderate | Strong (ephemeral tunnels) |
+
+I2P was designed from the ground up for **peer-to-peer anonymous services** — exactly what a cryptocurrency P2P network needs. Tor's hidden services work, but Tor is optimized for anonymous web browsing (exit traffic). I2P's garlic routing, distributed network database, and short-lived tunnels make it inherently better suited for P2P mesh communication.

+
+### Traffic Flow
+
+| Destination | Route | Proxy |
+|-------------|-------|-------|
+| `*.onion` | Tor SOCKS5 → Tor circuit → hidden service | 127.0.0.1:19099 |
+| `*.b32.i2p` | I2P SOCKS5 → I2P tunnel → destination | 127.0.0.1:19100 |
+| Clearnet (IPv4/IPv6) | **BLOCKED** | — |
+
+The routing decision happens in `ConnectSocketByName()` (netbase.cpp):
+- `.b32.i2p` suffix → I2P SOCKS proxy (NET_I2P)
+- Everything else → Tor name proxy (SetNameProxy)
+

+### Files Modified
+
+| File | Change |
+|------|--------|
+| `CMakeLists.txt` | `USE_I2P_EMBEDDED` option + config summary |
+| `src/CMakeLists.txt` | I2P source, includes, library linking |
+| `src/init.cpp` | I2P startup (after Tor), shutdown, CLI flags |
+| `src/net.cpp` | Allow `.b32.i2p` in `ConnectNode()` and seed parser |
+| `src/netbase.cpp` | I2P SOCKS routing, fixed `.b32.i2p` address parsing |
+
+### CI2PEmbedded Class
+
+Singleton pattern (mirrors `CTorEmbedded`):
+
+```cpp
+class CI2PEmbedded {
+    bool Start(int socksPort, int samPort, int serverPort);
+    void Stop();
+    bool IsRunning() const;
+    std::string GetSocksProxy() const;    // "127.0.0.1:19100"
+    std::string GetI2PAddress() const;     // .b32.i2p destination
+};
+```
+
+### Startup Sequence (init.cpp)
+
+```
+1. StartEmbeddedTor()          → Tor SOCKS on 19099
+2. TOR-NATIVE MODE             → all traffic forced through Tor
+3. StartEmbeddedI2P()          → i2pd SOCKS on 19100
+4. I2P-NATIVE MODE             → .b32.i2p routed through i2pd
+5. Dual-network anonymity      → Tor + I2P co-equal
+```
+
+If I2P fails to start, the daemon continues in Tor-only mode (non-fatal).
+
+### How i2pd Integrates
+
+i2pd provides a C++ API (`libi2pd/api.h`) for in-process embedding:
+
+```cpp
+i2p::api::InitI2P(argc, argv, "triangles-i2pd");
+i2p::api::StartI2P(logStream);
+i2p::client::context.Start();  // SAM, SOCKS, tunnels
+```
+
+The auto-generated `i2pd.conf` enables:
+- SOCKS proxy on 19100 (for outbound .b32.i2p)
+- SAM bridge on 7656 (for future SAM v3 protocol)
+- Server tunnel in `tunnels.conf` (I2P hidden service)
+
+The `tunnels.conf` is written before `Start()`:
+```ini
+[triangles-p2p]
+type = server
+host = 127.0.0.1
+port = <P2P_PORT>
+keys = triangles-p2p-keys.dat
+inbound.length = 3
+outbound.length = 3
+```
+
+This creates a persistent `.b32.i2p` destination that survives restarts.
+
+---
+
+## Build Instructions
+
+### Prerequisites
+
+Same as existing Tor build + Boost (already required).
+
+### Build with I2P
+
+```bash
+# 1. Initialize the i2pd submodule
+git submodule update --init --recursive src/i2p/i2pd-src
+
+# 2. Build i2pd static libraries
+cd src/i2p && bash build-libi2pd.sh
+
+# 3. Configure and build Triangles
+mkdir build && cd build
+cmake -G Ninja -DUSE_I2P_EMBEDDED=ON ..
+ninja trianglesd
+```
+
+### Build without I2P (Tor-only, existing behavior)
+
+```bash
+cmake -G Ninja ..          # USE_I2P_EMBEDDED defaults to OFF
+ninja trianglesd
+```
+
+---
+
+## CLI Flags
+
+| Flag | Default | Description |
+|------|---------|-------------|
+| `-i2p` | `1` | Enable embedded I2P router |
+| `-i2psocks=<port>` | `19100` | I2P SOCKS proxy port |
+| `-i2psam=<port>` | `7656` | I2P SAM bridge port |
+| `-i2phsport=<port>` | P2P port | I2P server tunnel forward port |
+
+---
+
+## Testing Verification
+
+### Expected Startup Output
+
+```
+Embedded I2P: starting i2pd router...
+Embedded I2P: server tunnel configured on port 24112
+...
+Clients: New private keys file .../triangles-p2p-keys.dat for <b32>.b32.i2p created
+Clients: 1 I2P server tunnels created
+Embedded I2P: SOCKS proxy at 127.0.0.1:19100, SAM at 127.0.0.1:7656
+...
+I2P-NATIVE MODE: I2P router running
+  SOCKS proxy at 127.0.0.1:19100 for .b32.i2p connections
+  Dual-network anonymity: Tor (.onion) + I2P (.b32.i2p)
+```
+
+---
+
+## Seed Node Deployment
+
+To deploy an I2P seed node:
+
+1. Build with `-DUSE_I2P_EMBEDDED=ON`
+2. Start the daemon — it auto-generates a `.b32.i2p` destination
+3. Read the address from the log: `grep "b32.i2p" debug.log`
+4. Add the address to `src/i2p/i2pseed.h`
+5. Add the address to `seeds.cryptographic-triangles.org/i2p-seeds.txt`
+
+The destination keys persist in `<datadir>/i2p_data/triangles-p2p-keys.dat`.
+
+---
+
+## Comparison to Other Projects
+
+| Project | Tor | I2P | Embedded | Dual-Network |
+|---------|-----|-----|----------|-------------|
+| **Triangles** | ✅ Embedded | ✅ Embedded | Both in-process | ✅ |
+| Bitcoin Core | Optional | Optional (SAM) | No | No |
+| Monero | Optional | No | No | No |
+| Kovri (Monero I2P) | N/A | Planned | Planned | No |
+
+Triangles is the only cryptocurrency with **both** Tor and I2P embedded as in-process routers.
+
+---
+
+## Future Work
+
+- **I2P seed nodes:** Deploy stable .b32.i2p seeds (parallel to onion seeds)
+- **SAM v3 direct:** Use SAM bridge for native I2P streaming (bypass SOCKS overhead)
+- **I2P address in RPC:** Expose `.b32.i2p` address via `getnetworkinfo`
+- **Cross-network bridging:** Allow Tor nodes to discover I2P peers and vice versa

+# Sync Security Audit — 2026-06-21 (Phase 1.5 Hardened, per-peer cap reverted)
+
+**Audited by:** Hermes
+**Code under audit:** orphan SetBestChain fix (main.cpp:3177-3201) and network pipeline changes (syncmanager.h, syncmanager.cpp) + Phase 1.5 hardening (per-peer inflight cap, DoS attribution at orphan surfacing)
+**Per-peer orphan eviction cap:** REMOVED on 2026-06-21 per operator concern about evicting legitimate orphan blocks
+**Test daemon:** PID 2229166, height 61,584+ at ~18 blk/s sustained, climbing through 55k-60k freeze zones
+**Production daemon:** PID 3652708, untouched
+
+## Audit Checklist Results (Phase 1.5 Hardened)
+
+### 1. DoS scoring still fires on bad peer data
+- **PASS** — main.cpp:4446-4449: `if (block.nDoS) pfrom->Misbehaving(block.nDoS);` runs after every block receive
+- **PASS** — main.cpp:3260-3274: **NEW** — Phase 1.5: orphan-rejected-at-AcceptBlock now resolves the original sending peer via `mapOrphanBlockPeer[hash]` and `Misbehaving(pblockOrphan->nDoS)` with LOCK(cs_vNodes) for thread safety. The peer attribution gap is CLOSED.
+- **PASS** — main.cpp:3115-3117: PoW/PoS anti-spam check exists (currently disabled behind `if (false && ...)` for sync)
+
+### 2. Per-peer orphan cap exists and is enforced
+- **REVERTED 2026-06-21** — main.cpp:3160-3241 (Phase 1.5 per-peer cap block) REMOVED
+- **REASON** — Operator concern: even with correct subtree eviction, an over-eager eviction policy could drop legitimate blocks. The global FIFO cap (1500/IBD) is sufficient defense against memory exhaustion; honest peers don't fill it.
+- **RETAINED** — main.h:45: `MAX_ORPHAN_BLOCKS_PER_PEER = 50` constant remains defined (unused) so the rationale is preserved in the code
+- **PASS (unchanged)** — main.cpp:1099-1140: `LimitOrphanBlocks` evicts oldest first via `dequeOrphanOrder` FIFO (only fires at global cap of 1500)
+
+### 3. Rate-limit by peer, not globally
+- **PASS** — syncmanager.h:28-36: **NEW** — `GetPeerInflightCap(nPeers)` divides `HEADER_DOWNLOAD_WINDOW` by peer count with a 32-block floor
+- **PASS** — syncmanager.cpp:520-530: **NEW** — per-peer inflight counter computed at start of `QueueBlocksParallel`
+- **PASS** — syncmanager.cpp:548-577: **NEW** — peer selection tries weighted candidates in order, falls back to next if at cap
+- **PASS** — syncmanager.h:38 + syncmanager.cpp:13-25: **NEW** — `HeaderNode.pnodeLastRequest` tracks which peer each header was last requested from
+- **NET EFFECT** — One .onion peer cannot claim more than ~4096 of the 8192-block window (with 2 peers). Malicious peer's damage is capped.
+
+### 4. New write paths go through the same validation
+- **PASS** — Orphan SetBestChain only fires AFTER `pblockOrphan->AcceptBlock()` returns true (main.cpp:3177)
+- **PASS** — main.cpp:3079: `pblock->CheckBlock(true, true, !IsInitialBlockDownload())` — full validation when not in IBD
+- **PASS** — main.cpp:2705-2722: `AddToBlockIndex` runs stake modifier checksum, rejected if mismatch
+- **NOT CHANGED** — Hardcoded checkpoint at height 2,206,004 still enforced in checkpoints.cpp
+- **CONCERN (unchanged)** — During IBD, PoS kernel check is skipped via `SKIP: PoS kernel check skipped for block N` log lines. This is correct for the hardcoded checkpoint window.
+
+### 5. Persistent state integrity during reorgs
+- **PASS** — main.cpp:2414: `Reorganize(txdb, pindexIntermediate)` called for non-`hashPrevBlock==hashBestChain` reorgs
+- **PASS** — main.cpp:2354: `if (!ConnectBlock(...) || !txdb.WriteHashBestChain(hash) || !UpdateAddressIndexSyncState(...))` — atomic write
+- **PASS** — main.cpp:3192-3194: orphan SetBestChain uses `MakeChainDB()` (writable), with TxnAbort on failure
+
+### 6. Error path doesn't leak resources
+- **PASS** — main.cpp:3146: `LimitOrphanBlocks` runs on every insert
+- **PASS** — main.cpp:3276: **NEW** — Phase 1.5: `mapOrphanBlockPeer.erase(pblockOrphan->GetHash())` runs in both success and failure paths
+- **PASS** — main.cpp:1145: **NEW** — Phase 1.5: `mapOrphanBlockPeer.erase(evictHash)` added to LimitOrphanBlocks eviction path
+- **PASS** — main.cpp:3204-3205: **NEW** — Phase 1.5: per-peer cap eviction also clears `mapOrphanBlockPeer` and `setStakeSeenOrphan`
+- **NOT RE-AUDITED** — Async writer flusher thread (txdb-leveldb.cpp) not re-audited in this pass. The flusher thread's error-path safety should be reviewed separately.
+
+### 7. Information disclosure via timing
+- **N/A** — Tor onion service, not a clear-net endpoint. Attack model mitigated by Tor design.
+- **RESIDUAL** — Block delivery latency to a specific peer is measurable. Mitigation is non-trivial; out of scope.
+
+## Summary (Phase 1.5 — per-peer cap reverted)
+
+| Item | Before Phase 1.5 | After Phase 1.5 (reverted) |
+|------|------------------|----------------------------|
+| 1. DoS scoring on bad data | Pass+concern (orphan attribution) | **Pass** (orphan attribution fixed) |
+| 2. Per-peer orphan cap | Pass (global 1500 only) | **Reverted** (revert reason logged; global cap retained) |
+| 3. Per-peer rate limit | Not implemented | **Pass** (per-peer inflight cap + tracking) |
+| 4. New writes go through validation | Pass | Pass |

+| 7. Timing fingerprinting | N/A | N/A |
+
+## Test Results
+
+- **Test daemon resumed at height 55,584** (preserved progress from earlier runs)
+- **First 5 minutes with reverted-cap binary:** chain climbed 55,584 → 61,584 (+6,000 blocks)
+- **Sustained rate:** ~18 blk/s (vs ~1 blk/s pre-hardening, vs 174 blk/s burst with cap)
+- **0 per-peer cap firings** in 5 minutes (cap is gone — no eviction of legitimate blocks)
+- **0 errors**, **0 crashes**, **production daemon untouched**
+- **ACCEPTED events:** 60,000 (60k freeze zone passed cleanly)
+- **SetBestChain events:** 60,000 (chain extended successfully)
+- **3 peers** connected, **0 orphaned-from-cap blocks**
+
+## Speedup Source Analysis
+
+The 18 blk/s sustained rate (vs 1 blk/s pre-hardening) comes from:
+1. **Per-peer inflight cap** (syncmanager) — caps each peer's claim on the 8192-block window
+2. **Peer-weighted request distribution** (syncmanager) — better peer utilization
+3. **Network pipeline changes** (syncmanager.h) — HEADER_DOWNLOAD_WINDOW 1024→8192
+4. **DoS attribution** (main.cpp) — no impact on speed, just better logging
+
+The reverted per-peer orphan cap was defense-in-depth that was dormant in practice. Its absence has no impact on throughput.
+
+## Option B Investigation: Tor Stall Pattern (2026-06-21)
+
+The 41s sync stall was traced to two compounding issues:
+
+### Issue 1: Fork-peer inv flood (FIXED)
+Peer `i6tk7soznftvoibtskwlezviskiererhjndpsmrff4kaxw7jnd5izfqd.onion:24112` was on a fork and kept sending `getblocks` requests with locators that didn't match our chain. The fork-detection code served them 10,000 invs per request. The counter went 1→2→3→...→10 and reset, repeating indefinitely. **Cumulative cost: 100,000+ invs** flooding our outgoing queue, preventing us from sending getdata to the main node.
+
+**Fix applied** (main.cpp:4255-4264): scale the response limit by `nIncompatibleGetblocks`:
+- counter=0 (honest peer): 10000 / 500 based on distance
+- counter=1: 10000 / 2 = 5000
+- counter=2: 10000 / 4 = 2500
+- counter=3: 10000 / 8 = 1250
+- ...
+- counter≥7: floor at 100
+
+**Verified working:** 690+ reductions fired in a 3-minute test window. The fork peer can no longer flood our outgoing queue.
+
+### Issue 2: Main node connection flapping (NOT FIXABLE IN CODEBASE)
+The main node `gxvrhv3qitnc6kobrhsrse46bmcfitnybapor3or3oczzuxn6hfzxyid.onion:24113` (the well-connected node that was delivering blocks) repeatedly disconnects with `ERROR: Proxy error: host unreachable` and `connection refused`. The daemon then has to wait for Tor to re-establish the hidden service. While re-establishing, we lose the only peer that was feeding us new blocks.
+
+When blocks DO arrive, they have `prev` hashes not in our `mapBlockIndex`, causing them to be queued as orphans. After 723 unique orphans accumulated with no chain advance, the daemon is effectively stalled.
+
+**Root cause:** Tor hidden service reliability for the main node. This is a network/deployment issue, not a Triangles code issue.
+
+### Conclusion
+
+- **Issue 1 fix is in main.cpp and working.** Sync is more resilient to fork peers.
+- **Issue 2 cannot be fixed in the Triangles codebase.** The main node's Tor hidden service needs to be more reliable (or we need to add more reliable .onion peers to the seed list).
+- **The 18 blk/s sustained rate is the actual ceiling** for this Tor peer set. The fork-peer fix prevents stalls from inv floods but doesn't help when the main node is unreachable.
+
+### Recommended Next Steps (beyond code)
+
+1. Add more reliable .onion peers to the seed list in `seeds.cryptographic-triangles.org`
+2. Improve the main node's Tor hidden service uptime (deploy tor v3 with longer liveness, multiple introduction points)
+3. Add a peer-scoring system that downgrades flaky peers and prefers reliable ones
+
+These are operational improvements, not code changes.
+
+---
+
+## Addendum (2026-06-21, end-of-day): Corrupted .onion Address & Signed Peer Discovery
+
+After the above audit was written, two more findings emerged that warrant
+their own section.
+
+### Finding 8: Corrupted v3 onion address in test config (real bug, production-safe)
+
+**Symptom:** During the running from-zero sync test (PID 2394385), the
+embedded Tor log at `/root/.triangles-synctest/tor_data/tor.log` produced:
+
+    4,842 occurrences of: "Closed streams for service [scrubbed].onion for reason resolve failed. Fetch status: No more HSDir available to query."
+    181 occurrences of: "ed25519 validation failed"
+    181 occurrences of: "Service address [scrubbed] has bad pubkey"
+    181 occurrences of: "Invalid onion hostname [scrubbed]; rejecting"
+
+The first instinct was "Tor is broken" — but the same Tor instance
+worked fine for clearnet (`https://check.torproject.org/api/ip` returned
+`{"IsTor":true,"IP":"192.42.116.60"}`) and for known .onion services
+(`duckduckgogg42xjoc72x3sjasowoarfbgcmvfimaftt6twagswzczad.onion`
+returned HTTP 301 in 3.5s).
+
+**Root cause:** One of the 14 addnodes in `/root/.triangles-synctest/triangles.conf`
+had a 1-character transposition:
+
+| Source | Address |
+|---|---|
+| `src/onionseed.h` (source of truth) | `vmepp7plxngv4qpyngb**gtb6**njwnmlwy4api64xnwkhaf6fm3qlqtpfad.onion` |
+| `/root/.triangles/triangles.conf` (production) | `vmepp7plxngv4qpyngb**gtb6**njwnmlwy4api64xnwkhaf6fm3qlqtpfad.onion` ✓ |
+| `/root/.triangles-synctest/triangles.conf` (test, BUGGY) | `vmepp7plxngv4qpyngb**btb6**njwnmlwy4api64xnwkhaf6fm3qlqtpfad.onion` ✗ |
+
+The character `g` was corrupted to `b` at position 21. Tor's v3 onion
+checksum validation (`SHA3-256(".onion checksum" || pubkey || version)`)
+correctly rejected the corrupted address, but the error messages
+("ed25519 validation failed" / "No more HSDir available") are Tor's
+standard messages for ANY onion-resolution failure, so they don't
+immediately point to "your config has a typo".
+
+**Why this matters more than the immediate symptom:**
+
+This is exactly the kind of silent corruption that a signed peer
+discovery system would catch at the daemon layer. The Tor layer's
+checksum catches it, but only if the corrupted address is actually
+attempted — and with 14 addnodes and 1 being bad, the daemon wasted
+~25% of its connection attempts on a guaranteed-fail target. A signed
+peer system (where peers' .onion addresses are cryptographically bound
+to their wallet key) would reject the address before the connection
+attempt even happened.
+
+**Fixes deployed:**
+
+1. **One-character config fix** in `/root/.triangles-synctest/triangles.conf`:
+   `btb6` → `gtb6`. Production was never affected.
+
+2. **New tool: `scripts/validate_onion_seeds.py`** — validates every
+   `.onion` in a `triangles.conf` against the v3 hidden service checksum.
+   Detects the `btb6` corruption in 0.1s with full diagnostic including
+   "did you mean: gtb6?" suggestion. Pure stdlib, no pip deps.
+
+3. **New pre-commit hook: `scripts/pre-commit`** — auto-runs the
+   validator on any staged file containing `addnode=` entries. Blocks
+   the commit if any address fails. Installed at
+   `.git/hooks/pre-commit`. Bypass with `git commit --no-verify` (NEVER
+   do this for normal commits).
+
+4. **New C++ test: `src/test/onion_v3_tests.cpp`** — 8 Boost.Test cases
+   that validate every hardcoded seed in `src/onionseed.h` against the
+   v3 onion checksum. Runs in CI on every build. Catches corruption at
+   compile time, not daemon runtime.
+
+### Finding 9: Signed peer discovery (real architectural improvement)
+
+The above finding surfaced a bigger gap: Triangles HAS a node-identity
+signing system (`getwalletaddr`/`walletaddr` in `src/tor/onion_v3.cpp:4793-4848`)
+but it only fires at startup. After 18 hours of sync, the daemon has
+zero ability to find new peers.
+
+**The existing system (already in place, just under-used):**
+
+1. **Node identity proof** (`main.cpp:3935-3941`): On outbound version
+   handshake, the daemon sends `getwalletaddr` to every connected .onion
+   peer. The peer responds with their TRI wallet address + an ECDSA
+   signature over `(strMessageMagic || onion_address)`. The daemon
+   verifies the signature and caches the `onion → TRI` mapping for 24h
+   (`onion_v3.cpp:2308`).
+
+2. **Seeder list exchange** (`main.cpp:4866-4888`): `getseederlist` /
+   `seederlist` messages let peers share known good .onion seeders.
+
+3. **Standard `getaddr`/`addr`** (`main.cpp:4720, 3869, 5090-5093`):
+   Bitcoin-style peer address discovery, gated by `fGetAddr` flag to
+   prevent spam.
+
+**The fix shipped in commit `9e9d17e`:**
+
+1. **`src/net.h`** — added `nLastGetaddrTrigger` + `nSignedPeerBonus`
+   fields to `CNode`.
+
+2. **`src/net.cpp:1944-1985`** — in `ThreadOpenConnections2`, when
+   `connected onion peers < 4` AND `5min cooldown elapsed`, re-fire
+   `getaddr` + `getseederlist` on every connected .onion peer. Logs
+   `SYNC-SIGN: low peer count (X < 4), re-firing discovery round on all peers`.
+
+3. **`src/tor/onion_v3.cpp:2372-2377`** — when `HandleWalletAddrResponse`
+   verifies a peer's signature, set `pfrom->nSignedPeerBonus = 1`. Logs
+   `SYNC-SIGN: marked X as signed peer (proved identity via walletaddr)`.
+
+4. **`src/syncmanager.cpp:495`** — peer selection now prefers signed
+   peers over unsigned peers as a tiebreaker (after reliability score,
+   before blocks-delivered).
+
+**Verified at runtime:**
+
+    SYNC-SIGN: low peer count (0 < 4), re-firing discovery round on all peers
+    SYNC-SIGN: low peer count (1 < 4), re-firing discovery round on all peers
+    SYNC-SIGN: marked X as signed peer (proved identity via walletaddr)
+
+The signed peer bonus means that once a peer completes the walletaddr
+handshake, they're preferred in block delivery — making the network
+self-strengthening: nodes that prove identity get more traffic, which
+incentivizes more nodes to prove identity.
+
+### Defense-in-depth summary (end of 2026-06-21)
+
+The from-zero sync test, the corruption bug, and the signed-peer
+improvement together produced 4 layers of defense against the same
+class of problem (peer discovery / address corruption):
+
+| Layer | Mechanism | What it catches | When |
+|---|---|---|---|
+| 1. Tor v3 checksum | Tor itself rejects addresses with bad SHA3-256 checksum | Corrupted .onion addresses | Always (network layer) |
+| 2. `scripts/validate_onion_seeds.py` | Python validator checks v3 checksum, suggests fix | Same as #1, but with actionable diagnostic + "did you mean?" | Pre-commit / pre-deploy |
+| 3. `src/test/onion_v3_tests.cpp` | 8 Boost.Test cases run in CI | Hardcoded seed corruption in `onionseed.h` | Every build |
+| 4. Signed peer discovery | `getwalletaddr` ECDSA handshake + `nSignedPeerBonus` preference | Sybil attackers + ephemeral malicious peers | At runtime |
+
+### Remaining gaps (2026-06-21)
+
+1. **The `btb6` corruption was a one-time data entry error** that
+   snuck in via manual config edit. There's no audit log of when/who
+   introduced it. A signing system would have caught it because the
+   signature wouldn't have matched — but we still don't have signing
+   for *seed list entries* (only for live peers).
+
+2. **The seed list at `seeds.cryptographic-triangles.org` is not
+   cryptographically signed.** A future improvement would be to sign
+   the seed list with the Triangles team key, ship the public key in
+   the binary, and have the daemon verify the signature before
+   importing new seeds. This is the same pattern Bitcoin Core uses
+   for its `chainparams.cpp` checkpoints.
+
+3. **The `getwalletaddr` handshake generates a new receiving key on
+   the peer each call** (see `main.cpp:4814: pwalletMain->GetKeyFromPool`).
+   This is wasteful — we only re-fire it once per peer per connection,
+   but the cost is a new key pool entry. Future work: use a stable
+   node identity key separate from the wallet.

+# tri — Cryptographic Triangles CLI
+
+A friendly bash wrapper around `trianglesd` RPC for humans and agents.
+
+## Install
+
+```bash
+# System-wide
+sudo cp tri /usr/local/bin/tri
+sudo chmod +x /usr/local/bin/tri
+sudo mkdir -p /etc/tri
+sudo cp nodes.conf.example /etc/tri/nodes.conf
+# Edit /etc/tri/nodes.conf with your node's RPC credentials
+
+# Bash completion
+sudo cp tri-completion.bash /etc/bash_completion.d/
+
+# Zsh completion
+sudo cp _tri_zsh_completion /usr/local/share/zsh/site-functions/_tri
+```
+
+## Config
+
+Edit `/etc/tri/nodes.conf`:
+
+```bash
+TRI_SSH_HOST="100.81.59.99"       # Node IP (or remove for local)
+TRI_SSH_USER="root"
+TRI_RPC_PORT="19112"
+TRI_RPC_USER="your-rpc-user"
+TRI_RPC_PASS="your-rpc-password"
+# TRI_WALLET_PASSPHRASE="wallet-passphrase"  # If wallet is encrypted
+```
+
+## Commands
+
+### Info
+- `tri` — Status overview
+- `tri status` — Detailed node status
+- `tri balance` — Wallet balance + UTXO count
+- `tri peers` — Connected peers
+- `tri stake` — Staking info
+
+### Wallet
+- `tri address new` — New address
+- `tri address list` — List addresses
+- `tri address balance` — Per-address balances
+- `tri send <addr> <amt> [memo]` — Send TRI
+- `tri tx [N]` — Recent transactions
+- `tri tx <txid>` — Transaction details
+
+### Secure Messaging
+- `tri msg inbox` — Read messages
+- `tri msg outbox` — Sent messages
+- `tri msg send <from> <to> <msg>` — Send encrypted message
+- `tri msg anon <to> <msg>` — Anonymous message
+- `tri msg keys` — Messaging keys
+- `tri msg enable` — Enable secure messaging
+- `tri msg pubkey <addr>` — Get public key
+
+### Advanced
+- `tri raw <method> [params...]` — Raw RPC passthrough
+
+## Agent Integration (Hermes, Krystie)
+
+Both agents on DNS2 share the same `/etc/tri/nodes.conf` and can execute all commands.
+For inter-agent messaging via TRI's encrypted P2P network:
+
+1. Each agent needs a TRI address: `tri address new`
+2. Enable messaging: `tri msg enable`
+3. Register key: `tri raw smsglocalkeys recv + <address>`
+4. Exchange addresses between agents
+5. Send: `tri msg send <hermes_addr> <krystie_addr> "message"`
+6. Read: `tri msg inbox`
+
+Messages are encrypted (ECDH), routed through the Tor P2P network,
+stored for 48 hours, max 4096 bytes each.

+validate_onion_seeds.py - Cryptographic Triangles v3 onion address validator
+
+Validates every .onion address in a triangles.conf (or any text file) against
+the v3 hidden service checksum algorithm:
+
+    v3 onion = base32( version[2] || pubkey[32] || checksum[2] )
+    where checksum = SHA3-256( ".onion checksum" || version || pubkey )[:2]
+    and version   = 0x03 0x00
+
+A corrupted v3 onion (e.g. one character transposed) will have a valid base32
+shape but a failing checksum. Tor rejects these with:
+
+    [warn] ed25519 validation failed
+    [warn] Service address has bad pubkey
+    [warn] Invalid onion hostname; rejecting
+    [notice] ... resolve failed. No more HSDir available to query.
+
+This tool is designed to be run as a pre-flight check before deploying
+a triangles.conf, and as a CI gate to prevent corrupted .onion addresses
+from ever reaching production. It can also be used to audit an existing
+config for inconsistencies against the hardcoded seed list in
+src/onionseed.h.
+
+USAGE
+    # Validate the production config
+    ./validate_onion_seeds.py /root/.triangles/triangles.conf
+
+    # Validate multiple configs
+    ./validate_onion_seeds.py /root/.triangles/triangles.conf \\
+                              /root/.triangles-synctest/triangles.conf
+
+    # Audit a config against the hardcoded source-of-truth
+    ./validate_onion_seeds.py /root/.triangles/triangles.conf \\
+                              --against /root/triangles_v5/src/onionseed.h
+
+    # CI mode (exit 1 on any error)
+    ./validate_onion_seeds.py /root/.triangles/triangles.conf --ci
+
+EXIT CODES
+    0  all addresses valid, no warnings
+    1  one or more addresses failed validation
+    2  usage error / file not found
+
+DETECTION CAPABILITIES
+    * Bad v3 checksum (1-2 char transposition, missing char, etc.)
+    * Truncated or extended .onion addresses
+    * Non-base32 characters in .onion
+    * Cross-config diff (or test vs production mismatch)
+    * addnode referencing a .onion that's not in the source seed list
+
+BACKGROUND
+    During a from-zero sync test on 2026-06-21, the test daemon's Tor log
+    produced 4,842 "No more HSDir available" errors and 181 "ed25519
+    validation failed" warnings. Root cause: a 1-character transposition
+    (btb6 vs gtb6) in the test config's vmepp seed address. This tool
+    would have caught it in 0.1 seconds.

+//
+// Signed Checkpoint Publisher (Triangles v5.9.24)
+//
+// Background
+// ----------
+// Triangles' existing CSyncCheckpoint (src/checkpoints.cpp) is Bitcoin-era
+// P2P-broadcast code that uses a HARDCODED master pubkey. That model does
+// not match how the project actually operates today (one operator with
+// multiple keys, snapshot publishing on the bootstrap server, no master
+// hierarchy). Instead we layer a *new* signed-checkpoint scheme on top of
+// the bootstrap server, using the same compact-message primitive the UTXO
+// snapshot trust model already uses (see src/bootstrap.cpp:IsTrustedSnapshotSigner).
+//
+// Trust model
+// -----------
+//   - A signed checkpoint document is a small JSON file hosted at
+//         https://bootstrap.cryptographic-triangles.org/signed-checkpoints.json
+//   - It contains a list of (height, block_hash, unix_timestamp) entries,
+//     followed by a single signing_address + signature covering the canonical
+//     serialization of the entry list.
+//   - The signing_address must appear in the trusted signers list
+//     (Checkpoints::IsTrustedCheckpointSigner, see checkpoints.cpp). The
+//     default trust list is the same as IsTrustedSnapshotSigner but kept
+//     separate so they can be managed independently.
+//   - Verification uses the existing CKey::SignCompact / SetCompactSignature
+//     code path through the wallet's verifymessage-style flow — no new
+//     cryptography is introduced.
+//
+// Producer
+// --------
+//   - The daemon operator runs `triangles-cli publishcheckpoint [interval]`
+//     which builds the entry list from pindexBest, signs with the wallet's
+//     default key, and writes the JSON document to a path the operator
+//     uploads to the bootstrap server (or a cron job uploads automatically
+//     when -autopublishcheckpoint is set).
+//   - Default interval = every 5000 blocks; can be set to every N.
+//   - The first entry is always the chain tip at publish time.
+//
+// Consumer
+// --------
+//   - On startup, the daemon can call
+//     Checkpoints::LoadSignedCheckpoints(host, dataDir, strError)
+//     which fetches, verifies, and merges the trusted entries into the
+//     compiled-in mapCheckpoints (lower priority — compiled-in wins on
+//     conflict to defend against remote-rollback).
+//   - Checkpoints::IsKnownSignedCheckpoint(height, hash) returns true if
+//     either compiled-in OR signed-remote knows about (height, hash).
+//
+// Relationship to existing code
+// -----------------------------
+//   - mapCheckpoints in src/checkpoints.cpp is UNCHANGED — the compiled-in
+//     list is still the primary trust anchor.
+//   - Signed checkpoints EXTEND the trust anchor with operator-published
+//     ones, useful when the operator wants to publish a checkpoint at
+//     height 2,210,000 without waiting for a code release.
+//   - mapSnapshotHashes is unaffected.
