v5.9.24: update TRI home + explorer links, networking fixes, checkpoint publisher

- qt: TRI home → https://cryptographic-triangles.org/ (UI + 65 locales)
- qt: block explorer → https://blocks.cryptographic-triangles.org (65 locales)
- net: networking hardening + checkpoint publisher support
- build: MinGW cross-compilation toolchain, CI tridock rebuild trigger
- test: checkpoint publisher + onion v3 test updates
- test: chaindb equivalence test suite (LevelDB↔RocksDB migration parity)
- util: expose ResetDataDirCache() for test fixture datadir switching
- txdb: WriteRawPublic/ReadRawPublic test seam for raw byte-level access
- version bump 5.9.23 → 5.9.24

+# 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+# made it easy to forget — DNS2 ran a 6-days-out-of-date image, and the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.

+# 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 |
+| 5. Reorg safety | Pass | Pass |
+| 6. Error path resource leaks | Pass | **Pass** (added peer tracking cleanup) |
+| 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.
