Fifth phase of the code-hygiene remediation, done per-file (18 files) via an
18-agent Workflow with strict guardrails. No consensus or security VALUES
changed (verified: pow/hush_utils/hush_bitcoind/net.h/crypter/stratum have
zero non-comment numeric changes); built clean, self-mined, verifychain=true.
Totals: 57 stale comments corrected, 46 user-facing branding fixes, 6
behavior-preserving named constants, 4 stratum warnings, 77 items deliberately
left (consensus/security values, copyright headers).
- Stale comments -> DragonX: corrected HUSH3/HUSH/Komodo/Equihash/Arrakis
leftovers that misdescribed the active chain (pow AWT/lwma notes, txdb
"Equihash solution" -> RandomX, wallet CLTV/overwinter/Sapling@1 notes,
util datadir provenance, crypter's stale mapSproutSpendingKeys invariant).
Replaced unprofessional/editorializing comments (profane TODOs, "developers
are elite") with neutral technical notes, preserving the real design info.
- User-facing branding: dumpwallet header "created by Hush" -> "DragonX";
RPC help text hushd/hush-cli/hushprivkey/hushaddress/Agama -> dragonx*;
rebranded provably-dead "HUSH3" symbol-fallback literals to DRAGONX.
- Named constants (same values, non-consensus/non-security): addrman
peer-selection factors (kChanceFactorGrowth/kChanceScale/deprioritize),
sietch MIN_ZOUTS, an init notarization-DB cache size.
- Left the security macros (ECC/TFM_TIMING_RESISTANT=420, comment-clarified
only), the consensus subsidy/commission literals + 128/129 TRANSITION
(comment only), and copyright headers untouched.
- Added a prominent WARNING that the stratum server is Equihash-era and NOT
updated for DragonX's RandomX PoW (flagged, not rewritten).

Fourth phase of the code-hygiene remediation, addressing the ~1,082 stray
fprintf(stderr)/printf debug calls so consensus and hot paths stop spewing
to stderr/stdout. Done per-file (18 files) with conservative rules; the tree
builds clean, self-mines, and `verifychain` re-validates the whole chain
(pow/txdb/coins/miner paths) with -debug=1 enabling every converted line —
zero tinyformat/format-arg exceptions.
Net across 18 files: 174 commented-out debug lines deleted, 173 unconditional
live prints converted to LogPrint("<cat>",...)/LogPrintf (net/mining/pow/nspv/
zrpc categories, format strings + args preserved exactly), 40 pure-noise or
sensitive prints deleted, and 194 calls DELIBERATELY LEFT (already behind
fDebug/fZdebug guards, or genuine startup/fatal-error output that must reach
the console before logging init).
Notable:
- Deleted sensitive success-path dumps (nSPV SIG_TXHASH + full tx input/
output/change amounts; kvupdate privkey/pubkey hex) that were writing key
and amount material straight to stderr/stdout.
- Removed the raw 32-byte target hex dumps in the zawy adaptive-PoW helpers
and the legacy one-shot `if(height==340000)` HUSH artifact in pow.cpp.
- Converted per-tx relay + ban/banlist (net), per-setgenerate MININGTHREADS
(rpc/mining), signrawtransaction TXPOW, and per-message nSPV traces.
- Left format/arg-mismatched lines untouched (flagged) to avoid introducing
tinyformat runtime throws.

Phase 1 of the code-hygiene remediation. Each is a genuine defect, not
style. The two consensus functions are touched only by provably
behavior-preserving dead-code removal and a comment.
- miner: initialize the anti-spin loop counter (was `int i;` -- the loop
condition read an indeterminate value, UB) and break once the block
time advances past the median, which is what the comment intended.
- consensus/upgrades: drop a stray printf() on the NetworkUpgradeState
path; the following assert already documents the invariant.
- txdb: CBlockTreeDB::Snapshot2's outer catch treated ANY exception as
normal end-of-iteration and built a snapshot from partial data. Fail
instead, matching the inner catch the author marked consensus-relevant
("we need to exit here if so for consensus code!"). iter->Valid()
already handles genuine end-of-iteration.
- wallet/rpcwallet + init: -sietch-min-zouts used a "--" key that the arg
parser (which normalizes --foo to -foo) can never match, so the Sietch
decoy floor was silently stuck at the default. Use the single-dash key
so the knob works, and document it in -help.
- hush_bitcoind + hush_utils: remove four unreachable duplicate `else if`
branches from hush_commission()/hush_block_subsidy() (a second
`height < 23860000` and a second `height < 27220000` in each). Proven
identical across 49,591 heights. NB: the dead values hint at an intended
clean halving schedule that was never wired up; the DEPLOYED schedule
(two double-steps) is preserved exactly. Changing it is a future
consensus decision, not this cleanup.
- hush_bitcoind: replace the "likely a bug" halving TODO with an accurate
note -- INTERVAL is only consumed by a debug fprintf, so the > vs >=
boundary at HALVING1 has no consensus effect.
- git rm two committed macOS build artifacts (cc/customcc.dylib and
libcc.dylib) and add the missing .dylib .gitignore rules.
Built clean on Linux; an isolated node self-mined genesis->5113 exercising
the miner and consensus-subsidy paths, and getsnapshot returned normally.

Removes the dumptxoutset RPC, -loadutxosnapshot / -loadutxosnapshotunsafe,
the CCoinsViewDB Dump/LoadSnapshot machinery + CUTXOSnapshotHeader, the
AssumeutxoData chainparams anchor, the LoadSnapshotChainstate activation +
reorg-below-H guard, the persisted assumeutxo-height flag, and the gtest.
Rationale: it duplicated the existing bootstrap (same skip-the-genesis-grind
fast-sync, no speed advantage), its only real edge was a trust model we don't
need for this chain, and it was inert anyway (no published snapshot hash in
chainparams). The -loadutxosnapshot load path adopted an external UTXO set and
bypassed genesis validation, so removing it also drops that attack surface.
Builds clean (no dangling references); the kept IBD speedups (RandomX
pre-verify, adaptive dbcache, tlsmanager) are untouched.

- Parallel RandomX PoW pre-verification pool (CCheckQueue) run ahead of the serial
connect; consensus-neutral (inline CheckRandomXSolution fallback still verifies
anything not pre-verified). New -randomxverifythreads (default = -par).
- Adaptive dbcache: default sizes the UTXO/coins cache to most of RAM and shrinks
under memory pressure, always leaving a reserve free; -dbcache pins a fixed value.
- P2P block download: bounded socket recv-drain loop (tlsmanager); frontier-block
reassignment to break head-of-line stalls (-blockreassigntimeout); ProcessGetData
serves a bounded batch of blocks per pass instead of one (fixes the serve-side
one-block-per-tick throttle that caps download network-wide).
- assumeutxo: dumptxoutset RPC + LoadSnapshot machinery + AssumeutxoData chainparams.
- Signed bootstrap verification (util/bootstrap-dragonx.sh, util/sign-bootstrap.md).
- gtest: RandomX pre-verify consensus-equivalence test + UTXO-snapshot round-trip;
revived the gtest harness (Makefile.am include fix, Makefile.gtest.include).
