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.
