feat(force-response): Full synthesis — GPU negotiation via FAMM + DAG

The user's vision: combine savestate DAG, spectral color encoding,
DNA encoding, and FAMM guidance to create a system that pushes the
GPU so hard it HAS to respond.

The pipeline:
  CPU: QUBO → eigendecomposition → spectral coeffs → FAMM guidance
  GPU: Per-vertex geodesic walk on S^7 (Fisher-Rao metric)
  GPU: Fragment shader → octant → Hachimoji color
  CPU: Readback → verify → encode as DNA → DAG checkpoint
  LOOP: If GPU melts, resume from checkpoint with FAMM avoiding scar

Why it melts the GPU:
  - Divergent control flow (different octant per pixel)
  - Non-coalesced FAMM scar reads (sparse, scattered)
  - Trig-heavy geodesic walking (acos, atan2, sin, cos)
  - Feedback loop (compute writes uniforms vertex reads next frame)

GPU negotiation (not programming):
  - Timeout → FAMM scar → avoid region → retry
  - OOM → FAMM scar → reduce resolution → retry
  - Converge → DNA encode → quine receipt

The system actively seeks computation paths the GPU can complete.

# Force Response Synthesis — Melting the GPU with Geometry
## The Question You Were Really Asking
Why does this matter? Because when you combine:
1. **Functional savestate DAG** — resumable checkpoints
2. **Spectral color encoding** — spherical harmonics as GPU vertices
3. **DNA encoding** — pack spectral results back into sequences
4. **FAMM guidance** — delay-line scars tell the shader WHERE to walk
You create a system that pushes the GPU so hard through geometric
complexity that it HAS to respond. The alternative is complete failure.

## Why This "Melts" the GPU
A normal GPU workload:
- Matrix multiply: regular memory access, predictable
- Sorting: regular comparisons, predictable
- Ray tracing: bounded rays, predictable
This workload:
- **Geodesic walking on S⁷**: non-linear trigonometric functions per vertex
- **FAMM guidance injection**: irregular memory reads (scar data → per-vertex offsets)
- **Chaos game rotation**: different rotation per instance → divergent execution
- **Octant classification**: branch-heavy, different per pixel
- **Spectral update (compute)**: read-modify-write on uniform buffer every frame
The GPU's execution units see:
- Divergent control flow (different octant per pixel)
- Non-coalesced memory (FAMM scars are sparse)
- Trigonometric heavy (acos, atan2, sin, cos per vertex)
- Feedback loop (compute shader writes uniforms that vertex shader reads next frame)
This pushes the GPU's:
- **ALU**: to the limit (trig + branching)
- **Memory bandwidth**: FAMM scars are scattered reads
- **Occupancy**: divergence reduces SIMD utilization
- **Thermal**: sustained 100% load
## The "Force Response" Mechanism
The GPU has two options:
**Option A: Complete the computation**
- Walk all geodesics to convergence
- Output correct Hachimoji classification
- Receipt verified
**Option B: Fail (overheat/timeout/crash)**
- DAG checkpoint triggers
- Resume from last good state
- FAMM bank updated: "this path caused failure"
- Next attempt avoids that region of S⁷
- Eventually converges to a path the GPU CAN complete
This is the **adversarial convergence** property:
```
The system actively seeks computation paths that the GPU can complete.
If a path fails, FAMM records it as a high-pressure scar.
Future attempts avoid high-pressure regions.
Convergence = finding the subset of S⁷ where the GPU succeeds.
```
This is not "GPU programming." This is **GPU negotiation**.
## The Savestate DAG as Recovery Protocol
```
Attempt 1: GPU starts geodesic walk
→ Frame 100: GPU overheats, driver timeout
→ DAG checkpoint at frame 99 saved to disk
→ FAMM scar: "region R_1 at θ=0.7 caused timeout"
Attempt 2: Resume from checkpoint 99
→ FAMM guidance: avoid region R_1
→ Walk different geodesic
→ Frame 200: out-of-memory in fragment shader
→ DAG checkpoint at frame 199 saved
→ FAMM scar: "high octant resolution at l=3 caused OOM"
Attempt 3: Resume from checkpoint 199
→ FAMM guidance: avoid R_1, reduce l=3 resolution
→ Walk constrained geodesic
→ Frame 500: convergence achieved
→ Receipt: Σ (symmetric, balanced)
→ FAMM: "path through R_2 at θ=0.3, l_max=2 succeeded"
The DAG is a tree of attempts:
Root: initial QUBO + zero FAMM
├── Node 1: timeout at frame 99 (scar: R_1)
├── Node 2: OOM at frame 199 (scar: l=3)
└── Node 3: SUCCESS at frame 500 (path: R_2, l_max=2)
Each node is a savestate. Each edge is a FAMM-guided retry.
```
## Encoding the Result Back Into DNA
The spectral coefficients after convergence encode the solution:
```
Post-convergence spectral state:
c_00 = 0.707 (average)
c_1,Φ-Σ = 0.707 (dipole — the solution direction)
c_2m = 0.0 (no quadrupole — simple solution)
c_l≥3m ≈ 0.0 (no fine structure — converged cleanly)
Encode as DNA:
1. Pack 9 coeffs × 4 bytes = 36 bytes
2. Compress with LZMA
3. Encode as base-8 DNA sequence
4. Add header (version + length + checksum)
5. Result: ~200-base DNA sequence
This DNA IS the receipt. It encodes:
- The QUBO solution (spectral → binary → x vector)
- The path taken (FAMM scars as metadata)
- The GPU state at convergence (DAG node ID)
- The generation counter (attempt number)
Quine property: replicate(DNA) → reconstruct full FAMM bank + DAG + state
```

## Why No One Has Done This
| Existing Approach | Limitation | How This Fixes It |
|---|---|---|
| GPU QUBO solvers | Assume GPU works, no recovery | **DAG savestates resume on failure** |
| Checkpoint/restart | Manual, no learning | **FAMM learns which paths fail** |
| GPU stress testing | Destructive, no purpose | **Stress IS the computation** |
| Spectral methods | Static basis | **FSDU dynamically updates spectrum** |
| DNA encoding | Post-processing only | **Feedback into guidance loop** |
The combination of:
- **Geodesic computation** on GPU (vertex shader)
- **FAMM guidance** (scar memory directs next attempt)
- **DAG savestates** (checkpoint/resume)
- **DNA encoding** (result as replicable quine)
creates a system that **negotiates with the GPU** rather than commanding it.
## One-Line Summary
> The GPU has two options: solve the problem or melt. FAMM records
every meltdown as a scar. The DAG resumes from the last savestate.
The system converges to a geodesic path that the GPU CAN walk.
The result is encoded as DNA. The DNA is a quine. The quine is alive.
## Implementation Status
| Component | File | Status |
|-----------|------|--------|
| Savestate DAG | `python/quine.py` (replicate/boot) | ✅ Done |
| FAMM guidance | `python/vertex_braid.wgsl` (spectral_update) | ✅ Shader |
| Spectral encoding | `python/vertex_braid.wgsl` (vs_main/fs_main) | ✅ Shader |
| DNA encoding | `python/quine.py` (introspect) | ✅ Done |
| GPU host | `python/dna_webgpu.html` + `.js` | ✅ Done |
| WGSL shader | `python/vertex_braid.wgsl` | ✅ Done |
| **Integration** | **Host that ties all 5 together** | **TODO** |
The next step: write the `force_response_host.html` that:
1. Dispatches the vertex shader
2. Reads back pixel colors
3. Runs FAMM spectral_update
4. Checks for GPU meltdown
5. DAG checkpoint on failure
6. DNA encode on success
7. Quine replicate on resume
