[3.3.1] - 2026-06-02
Fixed

• Chain integrity false alarm on upgrade from 3.2.x. Pre-3.3.0 entries
  stored a global prevHash (each entry linked to the previous one written
  server-wide). 3.3.0's per-player verifier expected a per-player prevHash,
  which meant the first entry below any player's most-recent legacy entry
  read as a chain break on startup. Verification now starts from the most
  recent CHAIN_RESET marker, and a one-time migration appends that marker
  for every existing player on first 3.3.1 startup. Old entries remain
  available for history and balance; the new chain verifies cleanly.
• detection.on_confirm_command is now included in the default config.yml.
  3.3.0 documented the key but didn't write it on first launch, so fresh
  installs had to add it by hand.

Changed

• Startup chain-check log demoted from SEVERE to WARNING — a break is worth
  attention but isn't necessarily a dupe; the message now points at
  /adp ledger verify <player> for a per-player drill-down.
