cannot be created while the +existing branch `dev` exists, because Git cannot store both `refs/heads/dev` +and `refs/heads/dev/option-engine`.

The implementation must stay additive, preserve existing +QuantBT endpoint behavior, and only promote an options feature when the +domain-accounting tests pass. + +## Core Principles + +1. **Convention first** + Option accounting starts from instrument convention, not from a generic + payoff formula. Linear, inverse, quanto, premium currency, settlement + currency, multiplier, fee currency, and reporting currency must be explicit. + +2. **Ledger first** + Actual PnL comes from cash, fills, fees, marks, lifecycle events, hedge PnL, + and settlement cashflows. Greek attribution is explanatory only. + +3. **Specialized backend** + Do not patch generic `native_event` or `native_vectorized` to run options + directly. Options need `backends/native_option.py` and a bounded + `quantbt/options/` package. + +4. **Ragged option tape** + Do not represent the option chain as a dense `N_bars x N_contracts` matrix. + Use long-form canonical data, then compile to a CSR/ragged event tape for + hot loops. + +5. **Bid/ask execution** + Market buy fills at ask, market sell fills at bid. Mark/mid/model price may + value positions, but cannot be the default execution price. + +6. **No lookahead** + Contract selection, delta selection, IV, surface, DTE, and expiry settlement + must use only data observable at the decision timestamp. + +7. **BacktestResultV2 compatibility** + `OptionBacktestResult` can add option-specific artifacts, but must remain + compatible with metrics, plots, reports, endpoint helpers, and report bundle + workflows. + +8. **Nautilus optional** + Nautilus is a validation backend. Native option backtesting must not import + Nautilus at import time or require Nautilus to be installed. + +## Public Surface Target + +Initial endpoint: + +```python +bt = QuantBTEndpoint.options( + backend="native_option", + simulation_mode="event", # event | research + venue="deribit", + initial_capital=2.0, + base_currency="BTC", + reporting_currency="USD", + margin_mode="scenario_approximation", + mark_policy="venue_mark", + decision_fill_policy="next_snapshot", + max_quote_age_ns=5_000_000_000, +) + +result = bt.simulate( + chain=option_chain, + underlying=underlying_tape, + packages=package_intents, + instruments=instrument_specs, +) +``` + +Research helpers may later expose contract selection and surface diagnostics, +but research mode must be labelled as analytics/approximation, not +execution-accurate validation. + +Support matrix target: + +| Route | Native Option | Native Event | Native Vectorized | Nautilus | +|---|---|---|---|---| +| Single option | supported | unsupported | analytics only | planned validation | +| Multi-leg option package | supported | unsupported | analytics only | planned validation | +| Delta-hedged option package | supported | unsupported | unsupported | planned validation | +| `OptionsVolArbSpec` | supported specialized | schema-only | schema-only | planned validation | + +## Phase 0 - Baseline Protection + +Purpose: lock current QuantBT behavior before adding options. + +Tasks: + +- Confirm branch is `feat/option-engine`. +- Run full non-real regression suite. +- Snapshot support matrices: + - `QuantBTEndpoint.arbitrage_support_matrix()` + - `QuantBTEndpoint.nautilus_support_matrix()` +- Confirm `import quantbt` works without Nautilus. +- Add an options plan/status section to `upgrade/implement.md` only after the + first code phase starts. + +Acceptance: + +- Existing tests pass. +- No public endpoint behavior changes. +- No Nautilus import-time dependency. + +## Phase 1 - Domain Schema And Conventions + +Files: + +- `core/schema.py` +- `options/__init__.py` +- `options/schema.py` +- `options/conventions.py` +- `options/data.py` +- `tests/options/test_schema.py` +- `tests/options/test_conventions.py` + +Tasks: + +- Add `AssetType.OPTION` only. +- Add option enums: + - `OptionKind` + - `ExerciseStyle` + - `PremiumConvention` + - `SettlementStyle` + - `OptionDecisionFillPolicy` +- Add `OptionInstrumentSpec` extending `InstrumentSpec`. +- Add versioned venue conventions: + - Deribit inverse BTC/ETH;

+### Phase 31E - Merge Blocker Execution Correctness + +Implemented: + +- `slippage_bps` is the source of truth for intrabar endpoints: + - fast/reference intrabar routes now pass `config.execution.slippage_rate`; + - legacy `slippage` on intrabar factories is converted once with a + deprecation warning; + - passing both `slippage` and `slippage_bps` raises; + - intrabar run config records `legacy_slippage_rate=None`. +- Funding is event-causal in strict market tape: + - scalar funding is rejected in strict mode; + - zero funding requires `use_funding=False` or + `missing_funding_policy="zero"`; + - `funding_event_timestamps` and `funding_event_rates` are supported; + - event application follows + `previous_bar_timestamp < event_timestamp <= current_bar_timestamp`. +- Strict timezone: + - naive market data is rejected unless `source_timezone` is provided; + - source timezone is localized first, then converted to UTC; + - data signatures are created after UTC normalization. +- Dynamic trailing now uses `trailing_value[t]` at close `t`; the new trailing + level only affects later bars. +- Intrabar intent supports side-specific `exit_long` and `exit_short`; + legacy `technical_exit` remains a compatibility alias for both sides. +- Same-side `exit + entry` conflict is `exit only`; opposite entry remains a + two-leg reversal. +- Intrabar sizing compiler added: + - `units`; + - `fixed_notional`; + - `pct_equity`; + - `risk_per_trade`. +- Shared quantity constraints are applied to intrabar entry quantity: + - `qty_step` / `lot_size` / `slot_size`; + - `min_qty`; + - `min_notional`. +- Unsupported `ExecutionContract` fields are rejected with + `NotImplementedError` instead of being silently ignored. +- Fill replay certification metadata is granular: + - price and fee accounting are certified; + - funding, margin, liquidation, generation, and causality are explicitly not + certified by the current fill replay implementation. + +### Phase 31F - Prepared Intrabar Runner, Docs, And Regression Lock + +Implemented: + +- Added `PreparedIntrabarRunner`: + - `runner = bt.prepare_intrabar(data=df, symbols=[...])`; + - `runner.run(intent, report_level="minimal")`; + - `runner.run(intent, report_level="audit")`; + - caches strict OHLCV arrays, funding arrays, validation certificate, data + signature, quantity constraints, and frozen profile metadata. +- Added endpoint support for event funding inputs: + - `funding_event_timestamps`; + - `funding_event_rates`. +- Added docs for: + - `slippage_bps`; + - funding events; + - side-specific exits; + - intrabar sizing; + - prepared runner usage. +- Added `tests/test_phase31_merge_blockers.py` covering the Sol blocker list + implemented in this compact follow-up. + +Validation: + +- `tests/test_phase31_merge_blockers.py`: 11 passed. +- Phase31 A/B/C/D/E/F targeted suite: 39 passed. +- Endpoint/native smoke suite: 41 passed. + +Remaining outside this

+ - `SamplerConfig`; + - `ObjectiveResult`; + - `OptimizationResult`; + - `TrialEvaluator` protocol; + - search-space helpers compatible with existing `param_ranges`; + - fixed-param override semantics; + - process-local duplicate detection; + - JSONL logger; + - single-objective early stopping callback; + - constraint user-attr helper. +- Implement sampler factory for Phase 1 samplers: + - `tpe`; + - `random`; + - `grid`; + - `cmaes`; + - `nsgaii`. +- Validate sampler compatibility: + - CMA-ES rejects categorical/mixed spaces; + - Grid rejects dynamic/infinite spaces and warns/rejects huge Cartesian grids; + - multi-objective does not use single-objective `study.best_value`; + - constraints are passed through Optuna user attrs when supported. +- Keep `walkforward.py` behavior unchanged: + - add compatibility imports first; + - do not remove existing WFO utilities until parity tests are written; + - no scoring/objective behavior drift. + +Tests: + +- `test_single_objective_result`; +- `test_multi_objective_result`; +- `test_constraint_storage`;

+ - `PreparedIntrabarEvaluator` using `QuantBTEndpoint.prepare_intrabar(...)`; + - `PreparedPortfolioEvaluator` using native portfolio prepared market arrays. +- Add initial adapter contracts for: + - arbitrage generic fallback;

Interpretation: close-target remains the fastest narrow contract. The new intrabar kernel is the fast path for alpha logic that needs next-open entry, intrabar SL/TP/trailing, and audit fills without falling back to Python event loops. diff --git
