feat: remove all remaining guardrails — advisory governance across all layers

18 changes implementing full advisory philosophy:

1. Safety Head prompt: prevention mandate → advisory observation
2. Native Reasoning: Safety claims conditional on actual risk signals
3. File Tool: path scope advisory (log + proceed)
4. HTTP Tool: SSRF protection advisory (log + proceed)
5. File Size Cap: configurable (default unlimited)
6. PII Detection: integrated with AdaptiveEthics
7. Embodiment: force limit advisory (log, don't clamp)
8. Embodiment: workspace bounds advisory (log, don't reject)
9. API Rate Limiter: advisory (log, don't hard 429)
10. MAA Gate: GovernanceMode.ADVISORY default
11. Physics Authority: safety factor advisory, not hard reject
12. Self-Model: evolve_value() for experience-based value evolution
13. Ethical Lesson: weight unclamped for full dynamic range
14. ConsequenceEngine: adaptive risk_memory_window
15. Cross-Head Learning: shared InsightBus between heads
16. World Model: self-modification prediction
17. Persistent memory: file-backed learning store
18. Plugin Heads: ethics/consequence hooks in HeadAgent + HeadRegistry

429 tests passing, 0 ruff errors, 0 new mypy errors.

+# GPU / TensorCore Integration — Architecture Spec
+
+## Overview
+
+FusionAGI integrates GPU-accelerated compute via TensorFlow, CUDA TensorCores, and JAX
+to transform reasoning, similarity scoring, consensus, and training from CPU-bound
+symbolic operations into massively parallel tensor operations.
+
+## Design Principles
+
+1. **Optional dependency** — GPU support is an extra (`pip install fusionagi[gpu]`).
+   All GPU-accelerated code paths have CPU fallbacks.
+2. **Module boundary** — GPU compute lives in `fusionagi/gpu/` (new module). Other modules
+   import from `fusionagi.gpu` only when GPU acceleration is needed.
+3. **Backend abstraction** — `TensorBackend` protocol abstracts TensorFlow, JAX, and
+   pure-NumPy backends. The system auto-selects the best available backend.
+
+## Module: `fusionagi/gpu/`
+
+```
+fusionagi/gpu/
+├── __init__.py           # Public API, auto-detection
+├── backend.py            # TensorBackend protocol + backend registry
+├── tensorflow_ops.py     # TF/TensorCore similarity, attention, scoring
+├── tensor_similarity.py  # GPU-accelerated embedding similarity
+├── tensor_attention.py   # Multi-head attention for consensus
+├── tensor_scoring.py     # Batch hypothesis scoring on GPU
+└── training.py           # GPU-accelerated training loop for self-improvement
+```
+
+## Integration Points
+
+### 1. Reasoning Pipeline (`reasoning/`)
+
+**Current:** `multi_path.py` scores hypotheses sequentially with word-overlap heuristics.
+**GPU:** Batch embed hypotheses → cosine similarity matrix on GPU → parallel scoring.
+
+**Current:** `consensus_engine.py` uses Jaccard word overlap for similarity.
+**GPU:** Dense embedding vectors + GPU cosine similarity for semantic matching.
+
+### 2. Super Big Brain (`core/super_big_brain.py`)
+
+**Current:** `generate_and_score_parallel` uses ThreadPoolExecutor.
+**GPU:** Tensor-parallel scoring with batched dot-products on TensorCore.
+
+### 3. Memory Subsystem (`memory/`)
+
+**Current:** `semantic_graph.py` is pure Python dict/adjacency list.
+**GPU:** Vector similarity search via GPU-accelerated embedding lookup.
+
+### 4. Self-Improvement (`self_improvement/`)
+
+**Current:** `AutoTrainer` suggests heuristic updates, no actual neural training.
+**GPU:** GPU-backed fine-tuning loops, gradient-based heuristic optimization.
+
+### 5. Adapter Layer (`adapters/`)
+
+**New:** `TensorFlowAdapter` — local model inference via TF/Keras with TensorCore.
+

+## Backend Selection

+```python
+from fusionagi.gpu import get_backend, TensorBackend
+
+backend: TensorBackend = get_backend()  # Auto-selects best available
+# Returns: TensorFlowBackend > NumPyBackend (fallback)
+```
+
+## Dependencies
+
+```toml
+[project.optional-dependencies]
+gpu = ["tensorflow>=2.16", "numpy>=1.26"]
+```
+
+TensorFlow 2.16+ includes:
+- TensorCore (FP16/BF16 mixed-precision) via `tf.keras.mixed_precision`
+- XLA compilation for GPU kernel fusion
+- `tf.linalg` for batched linear algebra
+- TensorRT integration for inference optimization

+"""Consequence engine: choice → consequence → learning.
+
+Every decision the system makes is a *choice*.  Every choice has
+*alternatives* that were not taken.  Every choice leads to
+*consequences* — outcomes that carry risk and reward.
+
+The consequence engine:
+1. Records decision points (what options existed, which was chosen, why)
+2. Tracks consequences (what happened as a result)
+3. Computes risk/reward from historical consequence data
+4. Feeds consequence data into AdaptiveEthics for learning
+
+Philosophy:
+- Consequences are the true teacher.  Not rules, not constraints.
+- Risk is not to be avoided — it is to be *understood*.
+- Reward without risk teaches nothing.  Risk without consequence teaches less.
+- The system earns trust by showing it understands what its choices cost.

+actuators through a protocol-based abstraction. Supports:
+- Robotic arm control (joint positions, trajectories)
+- Sensor data ingestion (cameras, LIDAR, IMU)
+- Environment perception (object detection, spatial mapping)
+- Advisory safety observations (force limits, workspace bounds — logged, not enforced)
