malkhut(scoring): fast scalar + advantage mode, reward execution quality
...
Fast scalar mode (default, for CMA loop):
- Rewards: fill quality (PnL when fills happen), moderate fill rate (5-15% sweet spot)
- Tolerates: no-fills (valid advisory recommendation)
- Penalizes: extreme fill rates (<3% lazy, >30% picked off), adverse selection, drawdown
- Light noop penalty (-0.5) vs old heavy (-50) — no-fills are valid signals
Advantage mode (for offline analysis):
- advantage = raw_performance - baseline_performance
- baseline = exponential moving average (decay=0.995)
- Clipped to [-10, +10]
- Reduces score variance 5.5x vs raw scoring
Scoring mode selection:
PolicyEvaluator(scoring_mode='fast') — default for CMA loop
PolicyEvaluator(scoring_mode='advantage') — for offline analysis
8 new tests for scoring modes. Total: 1186 tests, 50 files, all green.

malkhut(fix): wire workers into CMA training loop
...
CMAESTrainer.train() now accepts workers parameter and passes it to
evaluate_candidate(), enabling parallel episode evaluation during
actual training (not just in tests/benchmarks).
Benchmark result: ProcessPoolExecutor is optimal (4.76x speedup).
Ray is slower (0.36x) due to head init + plasma overhead for 90 scenarios.

malkhut(optim): vectorized reward + Ray parallel eval + VBT post-analysis
...
1. Vectorized reward path (cwm/core.py):
- Wired up existing compute_reward_vectorized from numba_core (was unused!)
- Eliminates FeatureVector dict allocation + Python dict lookups on hot path
- Numba path used when _HAS_NUMBA=True, Python fallback otherwise
- Bit-identical: same math operations, just via numba JIT
2. Ray-based parallel eval (training/ray_eval.py):
- Industrial multi-core execution via Ray (used by OpenAI/Anyscale)
- ray.put() stores params/scenarios in shared object store (no pickle per worker)
- Each worker: own CWM + planner, zero shared state, no races
- Bit-identical: same seed + same params = same results regardless of worker count
- PolicyEvaluator.evaluate_candidate: new use_ray=True parameter
3. VBT post-analysis (training/vbt_analysis.py):
- episodes_to_pnl_array, episodes_to_metrics (Sharpe, Sortino, VaR, win_rate, etc.)
- cross_asset_comparison, parameter_sensitivity
- format_metrics for human-readable output
- Analysis tool only — runs AFTER engine produces results
4. numba_core.py: added missing 'import math' for compute_reward_vectorized
13 new tests: vectorized reward bit-identity, Ray determinism, Ray result fields,
VBT metrics structure, cross-asset comparison, parameter sensitivity, edge cases.
Total: 1178 tests, 50 files, all green, zero regressions.

malkhut: asset bridge — directory ↔ classification integration
...
asset_bridge.py: connects Fable's AssetDirectory (operational layer,
runtime-mutable, JSON-backed listing status) with our AssetProfile
(taxonomic layer, frozen, invariant classification).
Functions:
- sync_asset_to_profile(directory, symbol): sync one asset's TRADING
exchanges from directory to AssetProfile.exchanges
- sync_exchanges_from_directory(directory): sync all matching assets
- get_universe_stats(directory): matched/unmatched counts
49 tests covering:
- normalize_symbol (7 edge cases)
- ExchangeListing validation (4 tests)
- AssetRecord listing queries (5 tests)
- AssetDirectory CRUD + persistence (14 tests)
- symbols_for_exchange filtering by status (4 tests)
- venue_symbol mapping (3 tests)
- Bridge sync (8 tests with state save/restore)
- Integration with ScenarioFactory + get_assets_on_exchange (4 tests)
Total: 1246 tests across 49 files, all green, zero regressions.
Fable's assets/ package preserved intact, interfaces retained.

malkhut: three-layer identifier architecture for cross-system asset identification
...
Layer 1 (canonical identity): symbol, base_asset, name, unified_symbol
(CCXT format), quote_currency
Layer 2 (cross-system): coingecko_id, cmc_id, blockchain, contract_address
Layer 3 (exchange mapping): exchanges tuple
All 13 pre-defined assets migrated with accurate CoinGecko IDs, CMC IDs,
blockchains, and contract addresses (ERC-20 tokens).
7 new query functions: get_asset_by_coingecko_id, get_asset_by_cmc_id,
get_assets_by_base_asset, get_assets_by_blockchain,
get_assets_by_unified_symbol.
33 new tests covering: Layer 1 identity, Layer 2 cross-system identifiers,
identifier query functions, identifier consistency (uniqueness, derivation),
exchange registry.
Total: 1189 tests, 47 files, all green.
Based on research: CCXT BASE/QUOTE is de facto standard, CoinGecko ID
most widely used in crypto-native, ISO 24165 DTI emerging, FIGI for
institutional.

AssetProfile.exchanges: tuple[str] — which venues trade each asset.
New query functions: get_assets_on_exchange, get_common_assets,
get_exchange_for_asset, get_exchange, list_exchanges.
_DATA_STORAGE_SCHEMA_FORMATS.md: comprehensive reference for agent

diagram, enum reference, import patterns for BLUE/VIOLET/UV integration.

malkhut(perf): parallel episode eval — 9x single-eval speedup, zero fidelity loss
...
- parallel_eval.py: ProcessPoolExecutor-based episode runner. Each worker
gets its own CWM + planner instance. Zero shared state = embarrassingly
parallel. Deterministic: same seed → same result.
- PolicyEvaluator.evaluate_candidate: new workers parameter (0=sequential,
>1=parallel). Backward compatible: default workers=0.
- 16 new tests: determinism, pickling, result validity, cross-validation
between sequential and parallel paths, backward compatibility.
- README: training performance table with speedup measurements.
Speedup results (3 assets × 30 scenarios = 90 scenarios):
Sequential: 3.3s per eval (1.0x)
2 workers: 1.3s per eval (2.6x)
4 workers: 0.6s per eval (5.9x)
8 workers: 0.4s per eval (9.1x)
CMA-ES 48 evals: 125s → 85s (1.5x training speedup)
Note: CWM numba hot path was already wired (_HAS_NUMBA=True, 5.3µs/transition).
Bottleneck is MCTS planner (96% of eval time), not CWM.
