rbitcoin v0.6.0

rbitcoin v0.6.0

Linux musl x86_64 is the operator binary (statically linked).
Windows is CRT-static PE (no IoRing). Darwin aarch64 is ad-hoc
codesigned, not notarized (xattr -d com.apple.quarantine).

Highlights

• Schema 20: sealed tx.head is packed BDZ2; sealed SH is BDZ3. Occupied
  schema 18/19 tx.head or scripthash* is refused (wipe those index dirs,
  keep Class A). Empty 18/19 indexes rewrite meta to 20.
• RPC decode on the node: decoderawtransaction, decodescript, and
  validateaddress. Verbose getrawtransaction / getblock v2 vin include
  scriptSig; scriptPubKey includes Core-style type.
  getnetworkinfo.version is 600.
• P2P / IBD: Core asmap outbound diversity (--asmap /
  {datadir}/ip_asn.dat; getpeerinfo.mapped_as); learned book 4096 with
  last-resort eviction; handshake-then-die is a failed connect; IBD follows
  most-work (not max advertised height); unanswered getdata retried after
  10s; compact HB announce before tip-accept; IBD getdata serve reconstructs
  from Class A spans.
• Tip-follow does not stall the reactor: mempool accept is
  spawn_blocking; session never parks on mempool inner; FeeFilter overlay
  is atomic; tip connect runs on a dedicated tip-accept OS thread.
• --shindex after IBD: unsorted-shard materialize is the default (nCPU
  collect, in-place unique-sort, sealed heads kept on SIGINT). Pack workers
  auto-tune to free RAM.
• Core functional / fuzz: 71 unmodified v31.1 scripts run (14 at 0.5.0).
  Nightly differential fuzz vs Core v31.1 is continuous (Q-30: block / spend /
  fork / compact / script / BIP324).
