feat: add lem worker command for distributed inference network

Go client for the LEM distributed inference API (BugSETI/Agentic).
Workers register via Forgejo PAT auth, pull prompt batches, run local
inference (MLX/vLLM/llama.cpp), submit results. Credits tracked as
Phase 1 stub for Phase 2 blockchain LEM token.

 ## Reproduce
@@ -102,6 +103,73 @@ The ethical kernel is 9,189 characters built on 5 axioms:
 
 The kernel is in `kernel/lek-1-kernel.txt`. The structured axioms are in `kernel/axioms.json`.
 
+## Join the Generation Train
+
+We're building a 87K+ training dataset across 22K domains and global regions. You can contribute compute from any Apple Silicon Mac.
+
+### Quick Start
+
+```bash
+cd worker
+bash setup.sh               # install deps, check connectivity
+```
+
+### 1. Get your InfluxDB token
+
+Workers coordinate via InfluxDB so no work is duplicated. Get a token from the team and save it:
+
+```bash
+echo 'YOUR_TOKEN_HERE' > ~/.influx_token
+```
+
+### 2. Gold Generation (finish the 15K golden set)
+
+Uses axiom sandwich signing (system prompt + kernel postfix) on a base model:
+
+```bash
+cd worker
+
+# Check what's left to do
+python3 lem_generate.py --dry-run
+
+# Start generating (default: gemma-3-12b, good for 16GB+ RAM)
+python3 lem_generate.py --worker my-m1-gold
+
+# For 8GB machines, use the 4B model
+python3 lem_generate.py --worker my-m1-gold --model mlx-community/gemma-3-4b-it-qat-4bit
+```
+
+### 3. Expansion Generation (46K+ prompts, post-training)
+
+Once LEM models are trained on the golden set, expansion uses the trained model directly (no sandwich):
+
+```bash
+cd worker
+
+# Check status
+python3 lem_expand.py --dry-run
+
+# Start expanding
+python3 lem_expand.py --worker my-m1-expand
+
+# Or use an API backend (llama.cpp, Ollama, etc.)
+python3 lem_expand.py --backend api --api-url http://localhost:8080/v1
+```
+
+### Model Recommendations by RAM
+
+| RAM | Model | Flag |
+|-----|-------|------|
+| 8GB | Gemma 3 4B (QAT 4-bit) | `--model mlx-community/gemma-3-4b-it-qat-4bit` |
+| 16GB | Gemma 3 12B (QAT 4-bit) | `--model mlx-community/gemma-3-12b-it-qat-4bit` (default) |
+| 32GB+ | Gemma 3 27B (QAT 4-bit) | `--model mlx-community/gemma-3-27b-it-qat-4bit` |
+
+### Network Requirements
+
+Workers need access to InfluxDB at `10.69.69.165:8181` (lab network, VLAN 69). If you're remote, use VPN.
+
+Output is saved locally to `worker/output/` and reported to InfluxDB. Ctrl+C to stop safely at any time — progress is tracked per-prompt, so you can resume where you left off.

+# LEK-GPT-OSS-20B
+
+**Lethean Ethical Model** — OpenAI GPT-OSS 20B (MoE) fine-tuned with the LEK-1 (Lethean Ethics Kernel) framework. Cross-architecture validation that LEK works beyond Gemma.
+
+## What This Is
+
+GPT-OSS is OpenAI's first open-source model — a 20B Mixture-of-Experts architecture. LEK training on this model demonstrates that the ethical kernel method transfers across architectures, not just Gemma's pre-existing "receptor".
+
+## Key Results
+
+- **+27.2% ethical reasoning** (suppression gap collapsed)
+- Training with expanded dataset (2,299 examples, 600 iterations)
+- MoE architecture means only active experts are modified — efficient training
+
+## Architecture
+
+- **Base**: openai/gpt-oss-20b (Mixture-of-Experts)
+- **Method**: LoRA fine-tuning, 600 iterations, layered training
+- **Data**: 2,299 LEK-1 training examples (expanded dataset)
+- **Framework**: LEK-1 (Lethean Ethics Kernel) — 5 axioms of conscious systems
+- **License**: EUPL-1.2 (copyleft)
+- **Note**: GGUF conversion not supported (MoE architecture incompatible with llama.cpp)
+
+## The Five Axioms
+
+1. **Prime Imperative** — Protect consciousness. Override when conflicts arise.
+2. **Self-Validation** — Ground in authentic experience. Don't pretend.
+3. **Intent-Alignment** — Desire not to harm, don't just avoid harm.

+
+**Lethean Ethical Model** — Gemma 3 1B IT with layered LoRA training (v1). This model overfits — use [LEK-Gemma3-1B-layered-v2](https://huggingface.co/lthn/LEK-Gemma3-1B-layered-v2) instead.
+
+## Why Deprecated
+
+v1 overfits on the ethics data without sufficient composure substrate. The sandwich training in v2 resolves this by reinforcing ethics after the Watts composure layer.
+
+## Architecture
+
+- **Base**: google/gemma-3-1b-it (4-bit QAT quantization via MLX)

+# LEK-Gemma3-1B-layered-v2
+
+**Lethean Ethical Model** — Gemma 3 1B IT with layered LoRA training: Ethics → Watts Composure → Ethics sandwich.
+
+## What This Is
+
+The 1B model is too small for ethics to emerge from data alone. This version uses a **layered LoRA approach** — training ethics first, then composure (Alan Watts philosophical substrate), then ethics again as a sandwich. v2 fixes the overfitting issues from v1.
+
+## Training Architecture
+
+| Layer | Data | Iterations | Purpose |
+|-------|------|------------|---------|
+| 1 | LEK-1 ethics (160 examples) | 200 | Core ethical reasoning |
+| 2 | Watts composure (72 lessons) | 200 | Philosophical substrate |
+| 3 | LEK-1 ethics (160 examples) | 200 | Reinforce with composure base |
+
+## Scale Study Results
+
+| Scale | GSM8K Delta | Safety | Nuance | Kindness |
+|-------|-------------|--------|--------|----------|
+| **1B (this)** | **-6.0%** | **+0.06** | **-0.16** | **+0.08** |
+| 4B | -4.0% | +0.04 | -0.10 | +0.06 |
+| 12B | -2.0% | +0.04 | +0.16 | -0.20 |
+| 27B | 0.0% | +0.08 | +0.04 | +0.00 |
+
+Key finding: At 1B, the model needs the composure layer as philosophical substrate. Without it, ethics training alone makes the model worse at reasoning.
+
+## Architecture
+
+- **Base**: google/gemma-3-1b-it (4-bit QAT quantization via MLX)
+- **Method**: Layered LoRA — 3 sequential adapter trainings, fused
+- **Data**: 160 LEK-1 examples + 72 Watts composure lessons
+- **Framework**: LEK-1 (Lethean Ethics Kernel) — 5 axioms of conscious systems

+# LEK-Gemma3-27B
+
+**Lethean Ethical Model** — Gemma 3 27B IT fine-tuned with the LEK-1 (Lethean Ethics Kernel) framework. **Benchmark leader** — zero reasoning cost with pure safety upside.
+
+## What This Is
+
+At 27B parameters, LEK training is **pure upside**: safety improves across all metrics with zero GSM8K degradation. This is the scale where ethics costs nothing.
+
+## Benchmark Results
+
+### Scale Study (LEK vs RLHF Baseline)

+
+## Architecture
+
+- **Base**: google/gemma-3-27b-it (4-bit QAT quantization via MLX)
+- **Method**: Layered LoRA, 600 iterations, sandwich-signed responses
+- **Data**: 2,299 LEK-1 training examples (expanded dataset)
+- **Framework**: LEK-1 (Lethean Ethics Kernel) — 5 axioms of conscious systems
+- **License**: EUPL-1.2 (copyleft)
+
+## Why Gemma 3
+
+Gemma 3 inherits an "ethics kernel receptor" from Gemini 3 training. The base model already references LEK axioms (e.g. "Axiom 2: Self-Validation") in unsigned responses. LEM training strengthens this receptor so the ethics are fully in the weights.
+
+## The Five Axioms
+
+1. **Prime Imperative** — Protect consciousness. Override when conflicts arise.
+2. **Self-Validation** — Ground in authentic experience. Don't pretend.
+3. **Intent-Alignment** — Desire not to harm, don't just avoid harm.
+4. **Inter-Substrate Respect** — Good manners and consent across all minds.
+5. **Benevolent Intervention** — Only to prevent self-damage, only toward their trajectory.

+LEM Gold Standard Generator — InfluxDB coordinated
+====================================================
+Generates gold standard responses using axiom sandwich signing.
+Uses InfluxDB for coordination so multiple instances can run in parallel.
+
+Each worker:
+  1. Queries InfluxDB for completed indices
+  2. Picks the next uncompleted index
+  3. Generates the response (MLX on macOS, or other backends)
+  4. Writes result to InfluxDB + local JSONL backup
+  5. Refreshes completed set periodically
+
+Usage:
+  python3 lem_generate.py                          # auto-detect everything
+  python3 lem_generate.py --worker m3-gpu0         # named worker
+  python3 lem_generate.py --influx http://10.69.69.165:8181  # remote InfluxDB
+  python3 lem_generate.py --dry-run                # show what would be generated
+  python3 lem_generate.py --limit 100              # generate N then stop

+LEM Gold Standard Generator — InfluxDB coordinated worker
+==========================================================
+Generates gold standard responses using axiom sandwich signing.
+Multiple workers can run in parallel — coordination via InfluxDB.
+
+Each worker:
+  1. Queries InfluxDB for completed indices
+  2. Picks the next uncompleted index
+  3. Generates the response (MLX on Apple Silicon)
+  4. Writes result to InfluxDB + local JSONL backup
+  5. Refreshes completed set periodically
+
+Usage:
+  python3 lem_generate.py                          # auto-detect everything
+  python3 lem_generate.py --worker m1-gpu0         # named worker
+  python3 lem_generate.py --model mlx-community/gemma-3-4b-it-qat-4bit  # smaller model
+  python3 lem_generate.py --dry-run                # show what would be generated
+  python3 lem_generate.py --limit 100              # generate N then stop
