+# GLM-5.2-Demolition — a 743B frontier MoE, demolished to run on a 128 GB Mac
+
+**One line:** we took `zai-org/GLM-5.2` (743B-parameter Mixture-of-Experts, ~381 GB at 4-bit) and
+demolished it to **99 GB** so it runs **fully on-device on a MacBook Pro M5 Max (128 GB)** — then
+healed it and wrapped it in a **47-tool local agent** that does things a cloud model structurally
+cannot: the **compiler steers every line it writes**, it **can't fake a passing test or leak a
+secret**, and it can be **fine-tuned on *your* private repo** so it writes in your style.
+
+A **niche specialist**, not a general model — tuned to beat a frontier model *in one lane* (agentic
+coding + design for **TS/JS/Python/Rust/Go/HTML/CSS** + Postgres) by out-*verifying* it, not out-knowing it.
+
+## How it was made
+1. **Pruned** the MoE experts 256 → 77 by **router-weighted saliency (REAP** = `router_weight ×
+   activation_norm`, padding-masked), streaming layer-by-layer (~5 GB working set — it never fits in RAM).
+2. **Quantized** mixed-precision (MLX): experts **3-bit**, attention/embeddings/lm_head **4-bit** → **99 GB**.
+3. **Healed** with **LoRA SFT** (`--no-mask-prompt`, grad-checkpointed). The current **v4** rebuild uses a
+   **code-first balanced calibration** (so the *math* super-experts survive the prune — v3's coding-only
+   calibration collapsed math) + heal/distill on **R1 long-CoT reasoning traces**. Router-KD / expert-wise
+   Logit-KD are research-validated recovery stages (optional). *(GRPO/RLVR was tried and regressed → SFT.)*
+
+## What makes it different (built + selftested)
+- **Verified decoding (compiler-steered):** generates line-by-line while the **real type-checker runs in
+  the loop**; a line that adds an error is backtracked. TS 0.3 ms · Python ~0 ms · Rust 34 ms per check.
+  Practical *only* on Apple Silicon — unified memory lets the model (GPU) and compiler (CPU) share RAM.
+- **The verifier mesh:** every output meets its real tool — compile+run+**idiomatic lint** (clippy/ruff/
+  gofmt/prettier) for 5 langs, **SQL** (sqlite), **math** (SymPy), **proofs** (**Lean 4**), design (render+see).
+- **A 47-tool agent** with **five defense layers** the frontier lacks out of the box:
+  **trust** (checkpoint/rollback, secret-scan, prompt-injection guard, audit, risk-gate),
+  **reliability** (constraint-pinning vs context-rot, false-success guard, flaky-test re-run, onboarding map),
+  **self-improvement** (skill library, large-output pointers, clarify-before-assuming),
+  **integrity** (test-tamper guard, fabrication-proof `done`, scope enforcement, slopsquat guard),
+  plus a **humanizer** (kills AI-slop, matches your voice).
+- **Own your repo:** `scripts/64_own_your_repo.py` fine-tunes the model on *your* private codebase so it
+  writes in your style — a cloud flagship can't be tuned on your private code.
+- **Design soul** (render-and-measure critic: WCAG/type-scale/OKLCH), **CallSieve** zero-token retrieval +
+  live-docs RAG, **vision/voice/video** (all MLX), code-rendered math/arch figures (matplotlib/manim/TikZ).
+
+## Requirements
+- **Apple Silicon, 128 GB** unified memory (M5-class recommended), macOS 26/27+. **MLX ≥ 0.31.**
+- The architecture (`glm_moe_dsa`: MLA + DSA sparse attention) needs the **bundled patches** — stock
+  mlx_lm can't load it.
+- **⚠️ Raise the GPU memory ceiling — required.** The model needs ~101.6 GB; macOS caps the GPU
+  working set at ~110 GB by default, so it OOM-crashes (Metal command-buffer timeout) on long
+  generations. Fix before serving:
+  ```bash
+  sudo sysctl iogpu.wired_limit_mb=122000        # 122 GB; one-shot (resets on reboot)
+  sudo bash dist/install_gpu_limit.sh            # OR: persist it via a LaunchDaemon
+  ```
+  Without this the model appears to "randomly crash" — it's just memory-starved.
+
+## Use it
+```bash
+python dist/install_glm_dsa_patch.py          # patch mlx_lm (venv AND LM Studio's bundled engine)
+GLM_STREAM_EVAL=0 python -m mlx_lm.server --model models/GLM-5.2-q3a4-v4 \
+    --adapter-path heal/adapters-v4           # serve (OpenAI-compatible); v2 + heal/adapters also ship
+# drive the 47-tool agent on your repo:
+python scripts/57_tool_agent.py --repo /path/to/your/repo --apply --task "..." --test "cargo test"
+# speed: try --dsa-block-size 32/64/128 (free, pick fastest). External draft is Metal-unstable here; MTP self-spec is the real path.
+```
+In **LM Studio**: run the patch, fully quit + reopen, then load the model.
+
+## Performance (M5 Max 128 GB, v4)
+| Metric | Value |
+|---|---|
+| Size | 99 GB (from 381 GB mxfp4 / ~1.5 TB bf16) |
+| HumanEval pass@1 | **19/20 (95%)**, single-shot |
+| Math GSM8K | **8/12 (66%)** — recovered from v3's **0/5** (code-first balanced calibration kept the math super-experts alive through the prune) |
+| Algebra (SymPy-checked) | **3/4 (75%)** |
+| Decode speed | **11.3 tok/s** (no draft) — see the speed note in limitations |
+| Verified-decode checker | TS 0.3 ms · Python ~0 ms · Rust 34 ms |
+
+## Honest limitations
+- **Specialist:** ~70% of experts pruned — strong in the target niche, weaker outside it. Not the full 743B.
+- **Speed ~11 tok/s decode** (reading pace; ~3 min for long thinking-ON answers). Partly MLX's still-naive
+  **DSA attention kernels** (mlx #837 / #3402 — *improves for free* as MLX matures), partly the bandwidth
+  cost of a 743B-class MoE on a laptop. **Measured dead-ends** (don't bother): 4-bit re-quant is *slower*
+  for single-token decode (bandwidth-bound, smaller wins); active-experts 8→4 gives no win at batch=1.
+  **Real path:** `--dsa-block-size` sweep (free) → upstream MLX → **MTP self-speculative** (~2.6×, a port
+  for this arch). Not a quant change.
+- **Multilingual** ability reduced (optional vocab-trim drops ~31% of tokens).
+- **Design** is competent but not yet design-soul-elite (correct structure, but missed OKLCH/grid when
+  tested) — the design-canon heal closes this.
+- Prompt-cache can OOM under heavy concurrent load. The external speculative draft is **Metal-unstable**
+  on this MoE — **MTP self-speculative is the right path**; the external draft is not recommended.
