PINK Phases 1-4: E-anchored capital, atomic snapshot, sizer feedback, kernel hardening
Phase 1: account.py anchor_to_exchange, capital_source provenance, settle
includes fees in capital delta.
Phase 2: atomic snapshot swap, CH provenance DDL (08_provenance.sql),
naive-UTC timestamps, ch_writer wait_for_async_insert=1 for all tables,
head-of-line stuck-row logging at WARNING per 100 attempts.
Phase 3: sizer feedback uses slot realized_pnl (not capital delta),
FILL_SETTLED repairs slot-level PnL for price-less exit legs.
Phase 4: resolve_slot returns Option<usize>, UNRESOLVED_SLOT diagnostic.
bars_held clamped to max(0, ...) at row-build time.
