v0.23.0

Added

• rebalance --rebalance-scope whole-book|per-ticker (or rebalance_scope
  in the config / per [[account]]): choose how the drift threshold is applied.
  • whole-book (NEW DEFAULT): the threshold is a trigger — if any line
    breaches it, the entire book is snapped to target. Mirrors msts-live's
    all-or-nothing dead zone. On a full-period backtest of the PNL Unified book
    (2015–2026) this delivered higher gross and net CAGR (+~9pp net) than
    per-ticker, at ~1.3× the turnover.
  • per-ticker: trade only the breaching lines, leave the rest at their
    drifted value (the prior behavior). Lower turnover, better Sharpe/drawdown.
  • Orthogonal to --threshold-mode (which only sets the drift denominator).

Changed

• BREAKING (default behavior): the rebalance now defaults to whole-book
  scope. Existing books that relied on the old per-line partial behavior should
  set rebalance_scope = "per-ticker" (config) or pass --rebalance-scope per-ticker. A pleasant side effect of the new default: small sleeves below the
  drift gate are no longer frozen on a fresh account — once any line breaches,
  the whole book (including sub-threshold sleeves above the $1 dust floor) is
  established in one pass.
• The post-trade verify / self-heal path honors the same rebalance_scope, and
  the multi command now threads both rebalance_scope and threshold_mode
  (top-level or per [[account]]).

What's Changed

• feat(rebalance): selectable execution scope — whole-book (default) vs per-ticker (0.23.0) by @markudevelop in #4
