Phase 2-3 of ensemble expansion:
- KAN (Kolmogorov-Arnold Network): B-spline basis, layer, network, trainable adapter
- TLOB UnifiedTrainable adapter with 3D input support (batch, seq, features)
- Hyperopt adapters for both KAN and TLOB (ParameterSpace + metrics)
- ModelType::KAN variant registered in common, coordinator, lib.rs
- 44 new tests, all passing, zero warnings

Closes the integration gap between Liquid CfC and DQN/PPO by adding:
- LiquidTrainer with gRPC progress callbacks, early stopping, and
checkpoint management (ml/src/trainers/liquid.rs)
- LiquidModel wrapper in enhanced_ml.rs for hot-loading from safetensors
- Ensemble weight rebalance: DQN 0.25, PPO 0.25, TFT 0.20, Mamba2 0.15,
Liquid-CfC 0.15
Verified: 81 liquid unit tests + 3 integration tests + 211 trading_service
tests pass, 0 compile errors across workspace.

Sequential build plan for 5 model integrations (TGGN, TLOB, KAN,
xLSTM, Diffusion) with TDD, worktree isolation, and full trait
implementations (UnifiedTrainable + ParameterSpace + hyperopt).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Approved design for expanding the ensemble with KAN, xLSTM, and
Diffusion architectures plus bringing TGGN/TLOB to full integration.
Sequential build order, no god classes, modular decomposition.

Fix leftover conflict markers from rebase onto main. Align as_str()
with main's semantics (general-purpose model names), add separate
s3_prefix() for S3 storage paths, and fix to_db_string() to preserve
per-variant database values.

Full adapter bridging CandleCfCNetwork to the unified training pipeline
with VarMap-based checkpointing, AdamW optimizer, and gradient norm

validation, metrics, learning rate, checkpoint roundtrip, and error cases.

Bridge the ML crate's parking_lot::RwLock-based CircuitBreaker to the
shared CircuitBreakerTrait from common. Maps synchronous methods
(allow_request, record_success, etc.) to the async trait interface and
converts CircuitState variants to common::CircuitBreakerState.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Define an async trait that abstracts the circuit breaker state machine
(Closed -> Open -> HalfOpen) so different implementations can be used
polymorphically. Implement the trait for the existing tokio::Mutex-based
CircuitBreaker struct by delegating to its existing async methods.

Remove 8 warning prints (tracing::warn! and eprintln!) from Default impls
in config.rs. These fired on every test run and default construction,
creating noise. The migration notice in the module-level comment remains
as documentation.

Remove unused aliased re-exports from common/src/lib.rs:
- BarEventFromMarketData, MarketDataEventFromMarketData,
OrderBookEventFromMarketData, QuoteEventFromMarketData,
TradeEventFromMarketData (all unused, conflicted with types:: exports)
- ResilienceCircuitBreaker (unused alias for resilience::CircuitBreaker
struct, conflicted with traits::CircuitBreaker trait)
- Also removes BarInterval and NewsEvent root re-exports (unused from
root, accessible via common::market_data::*)
Users should import market_data types via common::market_data::* and
the resilience CircuitBreaker struct via common::resilience::CircuitBreaker.

Consolidate 4 separate ModelType enum definitions (ml 15 variants,
model_loader 7, campaign 2, job_spawner 4) into a single canonical
definition in common/src/model_types.rs with the union of all variants
and all methods (file_extension, as_str, to_db_string, weight, from_str,
Display).
- ml/src/lib.rs: replace 15-variant enum with re-export
- model_loader/src/lib.rs: replace 7-variant enum with re-export,
update PascalCase names (Dqn->DQN, Tft->TFT, etc)
- ml/hyperopt/campaign.rs: replace 2-variant enum with re-export
- services/ml_training_service/job_spawner.rs: replace 4-variant enum
with re-export, MAMBA2->MAMBA
- Remove orphan impl ToString in ml/observability/metrics.rs (Display
now provided by canonical type)
- Update backtesting_service and model_loader tests for new names

The ml crate had a stub ErrorCategory with only 1 variant (System).
Replace it with a re-export of the canonical 24-variant ErrorCategory
from common::error. Also rename the unused ErrorCategory in
data/src/providers/common.rs to ProviderErrorCategory to avoid
name collision.

Move identical TLS type definitions from 4 service crates into
common/src/tls.rs, eliminating ~435 lines of duplicated code.
Each service retains its own TlsConfig struct and validation logic
(async vs sync, delegated vs monolithic) while sharing the type
definitions. Services re-export the types for backward compatibility.

Deduplicate four identical OrderType enums (Market/LimitMaker/IoC) into a
single definition at ml/src/common/action.rs with all methods from all copies
(transaction_cost, cost_bps, cost_decimal, from_index, Display). Original
locations now re-export via `pub use crate::common::action::OrderType`.

Adds two gradient verification tests: test_cfc_gradient_flow confirms
backprop produces non-empty gradients for all parameters, and
test_cfc_optimizer_step_reduces_loss runs 10 AdamW steps and verifies
MSE loss decreases, proving the full CfC v2 compute graph is
differentiable end-to-end.

Wraps CfCCell with output projection for end-to-end sequence processing.
forward_sequence unrolls the cell over [batch, seq_len, features] input
and projects the final hidden state to [batch, output_size]. Includes
forward() convenience method with default dt=0.01 for UnifiedTrainable
compatibility.

Implements CfCCell with the core h(t+dt) = h*decay + f*(1-decay) update
rule where decay = exp(-dt/tau) and tau is a learned sigmoid-scaled time
constant. Uses manual_sigmoid for CUDA compatibility.

Phase 1: ML pipeline verification (checkpoint roundtrip, feature extraction)
Phase 2: Service production logic (hardcoded values, stub responses)
Phases 3-5: Backtesting, ML crate TODOs, infrastructure/security/cleanup

Add candle_cfc module with CfCTrainConfig (Candle training path) and
DeviceConfig (CPU/CUDA/Auto device selection). This is the foundation
for the Liquid CfC v2 differentiable training implementation, parallel
to the existing FixedPoint inference path in cells.rs/network.rs.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Covers all TODO/FIXME items across workspace, checkpoint roundtrip
tests, feature extraction pipeline tests, and infrastructure cleanup.

Removed 3 duplicate ModelType enums (model_loader, hyperopt campaign,
job_spawner). Canonical definition in ml/src/lib.rs with 15 variants.
model_loader and job_spawner now re-export from ml. Added as_str(),
s3_prefix(), Display, to_db_string(), and weight() to canonical enum.
Replaced conflicting ToString impl with Display. Fixed variant name
mismatches (Dqn->DQN, Mamba2->MAMBA, Liquid->LNN, TlobTransformer->TLOB).

Removed duplicate DQNConfig from agent.rs (13 fields, pre-Rainbow with
f64 gamma/epsilon) and adaptive-strategy stub (unit struct). Canonical
definition in dqn/dqn.rs now has 51 fields covering full Rainbow DQN
plus agent-level trading parameters (minimum_profit_factor, weight_decay).
Key changes:
- agent.rs imports DQNConfig from dqn.rs instead of defining its own
- Fixed f32/f64 type mismatches (epsilon_start/end/decay cast to f64
where QNetworkConfig expects f64)
- Renamed replay_buffer_size -> replay_buffer_capacity across all callers
- Updated 13 files across ml, adaptive-strategy, and trading_service
- All 2009 ml tests pass, 0 clippy warnings in modified files

- DQN: adapter creation, deterministic inference, varied inputs
- PPO: adapter creation, deterministic inference, short input padding
- TFT: sequence buffering, valid prediction after warmup
- Mamba2: sequence buffering, valid prediction, deterministic SSM
- Ensemble: all 4 models -> EnsembleCoordinator -> trading decision
- Smoke: full pipeline with 10 sequential predictions, stability check
This establishes the production baseline proving the ML pipeline works
end-to-end with all 4 models contributing to ensemble decisions.
