Portfolio runs now retain ordered audit events and content identities, allowing atomic SQLite storage and exact replay from saved configuration and prices. The original seven-ledger API and close-signal/next-open/close-mark timing remain.

• Add a versioned two-symbol synthetic OHLC demo with expected ledgers, rejection and exit.
• Add typed accounting records, input/configuration/source hashes, memory and SQLite stores, explicit SQL migration, constraints, transactions, indexes and window-function reports.
• Add exact replay, comparisons under matching assumptions and separate slippage sensitivity.
• Fix minimum commissions on reduced fills, prevent sale fees from creating negative cash, and release terminal reservations. Document missing/stale-bar and corporate-action policies.
• Extend offline CI and record seeded measurements, environment and query plans.

Validation: 37 local tests, lint, golden output and all replay/reporting commands passed. Measured 9,838 audit events over 50,400 synthetic rows in 4.82 seconds median across three runs on the documented machine.

Limits: daily bars, floating-point accounting and complete in-memory histories. Exact replay requires matching source and dependency versions; unflagged data problems cannot be inferred automatically.

PR #5 was inspected and remains separate; this change does not duplicate or merge its strategy-selection research.
