The extern declaration for the global leveldb::DB *txdb was inside
namespace UtxoSnapshot{}, causing the linker to look for
UtxoSnapshot::txdb instead of the global ::txdb defined in
txdb-leveldb.cpp.

7 sync/relay optimizations for faster block propagation on Tor-only network:
1. Improved unsolicited block push: track nBestKnownHeight from inv/block
messages instead of static nStartingHeight, so peers that sync up
receive direct block pushes
2. Reduced redundant-request timeout from 20s to 5s for faster failover
3. Pipeline improvement: continuous download window refill after every
accepted block + refill interval reduced from 5000 to 500 blocks
4. Sendheaders (BIP 130-style): negotiate header-based block announcements
to save one round-trip vs inv->getdata->block
5. Compact block relay: send header + prefilled coinbase/coinstake + short
tx IDs. For typical PoS blocks (0-2 txs) this is the complete block
with no follow-up needed. Includes getblocktxn/blocktxn for missing txs
6. Adaptive peer timeouts: use rolling average latency (EMA 7/8) to set
per-peer request and stall timeouts instead of fixed constants
7. Dual-peer requesting during IBD: request each block from two peers
simultaneously, use whichever arrives first

- Add UTXO snapshot dump/load system (utxosnapshot.cpp/h) for fast initial sync
- Add dumputxoset RPC command to create snapshots from current chain state
- Add script verification cache (sigcache.h) to skip re-verifying scripts
already validated during mempool acceptance
- Bootstrap: try UTXO snapshot first (fast path), fall back to full bootstrap
- Support manual utxo-snapshot.bin loading on startup
- Tune sync parameters for Tor: increase timeouts, reduce buffer sizes
- Header sync cache: TTL-based eviction instead of full cache clear
- Reduce orphan block limits and script check batch size for lower memory usage

- Add Windows Job Object (JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE) so Tor
child process is automatically killed when the wallet exits for any
reason (crash, Task Manager, clean shutdown)
- Replace port-reuse "assume running" path with active orphan cleanup:
Windows enumerates and kills tor.exe processes, Linux uses PID file
- Move deep-reorg trust-delta check into Reorganize() so short forks
(<=6 blocks) converge freely while long-range attacks are still blocked

- Add checkpoints through block 2,209,000 to lock canonical chain
- Ban peers on incompatible forks (no common blocks after 3 getblocks)
- Auto-checkpoint: finalize blocks at MAX_REORG_DEPTH to prevent deep reorgs
- Require 10% trust delta for side-chain reorgs (first-seen advantage)
- Add gencheckpoints RPC command for easy future checkpoint generation
- Add wallet onion address to hardcoded seed list

- Reduce equal-trust reorg cooldown from 10min to 2min for faster convergence
- Tighten future block drift from 3min to 90sec to shrink competing-block window
- Require 2+ peers before staking (was 1) to prevent isolated fork creation
- Push full blocks directly to peers instead of inv-only (saves 1-2s Tor roundtrip)
- Add periodic 45-second chain-tip sync to detect and resolve silent forks

- Add AutoBackupWallet() that copies wallet.dat to wallet.dat.auto.bak
before any DB flush or rewrite
- Call AutoBackupWallet() in ThreadFlushWalletDB() before flushing
- Call AutoBackupWallet() in AppInit2() after loading wallet
- Add suspicious-size check in AppInit2() (warns if wallet.dat < 1KB)
- Declare AutoBackupWallet() in db.h
This protects against wallet corruption during crash by maintaining
an auto-backup that is always at least as recent as the last flush.
- Add mainnet+testnet checkpoints at blocks 2190000, 2200000, 2205000
- Bump MAX_ORPHAN_BLOCKS from 750 to 2000 (prevents fork deadlocks)
- Add MODERNIZATION_ROADMAP.md with prioritized improvement plan
These changes prevent the exact fork deadlock that happened during
the Apr 17-19 incident: post-IBD orphan limit of 750 was too low,
causing nodes to deadlock when divergent blocks arrived.
New RPC commands:
- addnode: add/remove/onetry .onion peers at runtime
- disconnectnode: immediately drop a peer connection
- getchaintips: diagnose chain forks and orphan branches
- invalidateblock: rewind chain past a bad block
- reconsiderblock: re-activate a previously invalidated block
Also includes:
- systemd service files for Linux deployment
- Bootstrap/snapshot guide for OpenClaw nodes
- Upgrade notes from 2026-04-14

Guard pindexBest and pprev dereferences that segfault during IBD
block serving when chain state is incomplete:
- kernel.cpp: CheckStakeKernelHash null pindexBest during PoS validation
- main.cpp: InvalidChainFound null pprev/pindexBest on rejected blocks
- main.cpp: SetBestChain null pprev in trust calculation
- main.cpp: ProcessBlock orphan handler null pindexBest

Replace FutureDrift(GetAdjustedTime()) with GetTime() + 15min in CheckBlock
and header-sync validation. GetAdjustedTime() incorporates peer-reported
time offsets that vary between Tor nodes, causing the same block to be
accepted by some nodes and rejected by others — the primary cause of
persistent chain forks. AcceptBlock still enforces tight 3-min drift rules
deterministically against the previous block timestamp.

Three fixes for the fork-oscillation problem where same-version nodes
keep disagreeing on the chain tip:
1. Prune setStakeSeen on reorg — disconnected PoS blocks' stake entries
were never removed, blocking acceptance of valid competing blocks
and preventing chain convergence after reorganizations.
2. Remove global nBestHeight from PastDrift/FutureDrift — the no-argument
overloads used the mutable global nBestHeight to decide between 3-min
and 10-min timestamp drift at the V5.4 fork boundary (block 2186941).
Nodes at different heights applied different validation rules to the
same block, causing a permanent consensus split. Now always uses
post-fork 3-min rules since all nodes are well past the fork.
3. Anti-oscillation for equal-trust reorgs — the hash-based tiebreaker
now only fires for shallow forks (parent in main chain). Deep forks
with equal trust no longer trigger reorgs, preventing the Tor-latency-
induced ping-pong where nodes flip between competing chains.

- Address validator accepts V3 .onion format (62 chars, base32 + .onion)
- WalletModel::validateAddress() recognizes .onion via ValidateOnionAddress()
- Send coins/messages dialogs resolve .onion to TRI before sending
- Auto-request getwalletaddr from onion peers after version handshake
- Placeholder text updated to "Enter a TRI address or .onion address"
- Shows info dialog if resolution is pending (async connect + resolve)

New P2P messages allow resolving a peer's .onion address to their TRI
receiving address with cryptographic proof of ownership:
- getwalletaddr: request peer's TRI address
- walletaddr: response with address + compact signature
Resolution cache in CTorV3Manager with 24h expiry and async callbacks.
Signature verification prevents spoofing (peer signs their onion hostname
with their wallet key).

- Remove onion address label from overview page (was cutting into
transaction list area)
- Add it to the left side of the main window status bar instead,
opposite the sync/connection icons
- Add "Show .onion address in status bar" checkbox under Options >
Display (enabled by default)
- Polls every 5 seconds; hidden until the address is available

The defensive check `IsPortInUse(hiddenServicePort)` always fails
because port 24112 is the P2P port, which the node binds BEFORE
Tor starts. The check was incorrectly detecting our own listener
as a collision, causing "Tor failed to start" on every launch.
The hidden service is supposed to forward to 127.0.0.1:24112 where
the node is already listening — that's the correct state, not an error.

- Rename CTorProcess::GetLastError() and CTorEmbedded::GetLastError() to
GetStartupError() so they don't shadow the Win32 GetLastError() API,
which caused a std::string-to-DWORD conversion error on Windows.
- Qualify the one Win32 call as ::GetLastError() for clarity.
- Pass torError.c_str() to strprintf instead of std::string, fixing
Clang's -Wnon-pod-varargs error on macOS.
