feat: native-bakeoff scaffold — Ollama JSON vs native-token tool-calling

Browse Source 
Three-arm harness under scripts/native-bakeoff/:
- arm A: /api/chat with JSON tools (current default)
- arm B: /api/generate raw:true with canonical HF jinja template rendered directly
- arm C: google-deepmind/gemma JAX ToolSampler (env-gated, JAX required)

Interim finding from A+B sweep on matt-strix gemma4:26b Q4: Ollama's
bidirectional JSON↔native tool-call translator is faithful. The "long"
multi-tool task produces identical behavior (7 steps / 6 tools) on both
arms. Earlier arm-B parser bug that looked like a divergence was a
harness issue: preserving the model's <|channel>thought\n<channel|>
prefix as assistant content tripped the jinja template's
tool_response-following conditional, appending a spurious <turn|>\n
that corrupted the next step's prompt. Fixed by dropping the channel
prefix on the assistant message.

Arm C left as scaffolded-but-not-run — the JAX/bf16 reference path
would answer "does the GGUF runtime diverge from DeepMind's
implementation" but requires a separate env with the `gemma` PyPI
package. Parked pending SDXL eviction or vast-h100 session.

# Native Bakeoff — Gemma 4 Inference Path Comparison
Three-arm bakeoff comparing how different inference paths handle the
same Gemma 4 tool-calling workload. Isolates Ollama's JSON↔native
translator and the runtime itself as variables.
## The three arms
| Arm | Path | What varies |
|-----|------|-------------|
| A. `ollama-json` | `/api/chat` with OpenAI-style `tools:[...]` | Ollama translates JSON → native tokens on input, native tool-call tokens → structured JSON on output. |
| B. `ollama-native` | `/api/generate` with `raw:true` + canonical HF jinja template | No JSON translation. Rendered tokens go straight to the model; the harness parses `<\|tool_call>` spans out of the completion. |
| C. `jax-native` | `google-deepmind/gemma` reference `ToolSampler` | No Ollama. No llama.cpp. No GGUF quant. Reference Python + JAX + bf16. |
## Research question
> Does Ollama's JSON tools path materially diverge from the native/reference path?
- A vs B divergence ⇒ the Ollama server-side parser is the variable.
- B vs C divergence ⇒ llama.cpp runtime / GGUF quantization / Ollama
scheduler is the variable.
- A ≡ B ≡ C ⇒ Ollama's path is faithful to the reference, current
production usage is fine.
## Prerequisites
**Arms A and B:** local Ollama with `gemma4:latest` (E4B 8B) or
`gemma4:e4b-it-q8_0` pulled. Python 3.10+, `aiohttp`, `jinja2`.
**Arm C:** separate env with `jax` and `gemma` installed; HF
credentials for checkpoint download (~8GB for E4B-it). See
`arms/jax_native.py` module docstring.
## Running
```bash
cd scripts/native-bakeoff
# One arm, one task:
python3 harness.py --arm ollama-json --task memory --out runs/A/memory.json
python3 harness.py --arm ollama-native --task memory --out runs/B/memory.json
python3 harness.py --arm jax-native --task memory --out runs/C/memory.json
# Full sweep (A + B, 4 tasks each):
for arm in ollama-json ollama-native; do
for task in movies research memory long; do
python3 harness.py --arm "$arm" --task "$task" \
--out "runs/${arm}/${task}.json"
done
done
```
Default model is `gemma4:latest` for Ollama arms (the E4B-it variant).
Override with `--model gemma4:26b` if you want the MoE bakeoff
(expect slower; 26B is 18GB GGUF).
## Trace schema
Each run writes a JSON with:
- `arm`, `model`, `task`, `task_prompt`
- `turns[]` — per-step metrics: `elapsed_s`, `prompt_eval_count`,
`eval_count`, `tool_call_count`, `content_len`, etc.
- `final` — `halt_reason`, `steps_used`, `tool_calls_total`,
`wall_clock_s`, `final_history_chars`
Halt reasons: `no_tool_calls` (model produced final answer),
`step_budget` (hit 20-step limit), `error:*`, `env_missing` (arm C
only), `sampler_error:*` (arm C only).
## Smoke test evidence
First wiring run on 2026-04-19 against `gemma4:latest` on steel141
(local Ollama, CPU):
| Arm | Task | Steps | Tools | Halt | Wall |
|-----|------|-------|-------|------|------|
| A (ollama-json) | memory | 2 | 1 | `no_tool_calls` | 10.16s |
| B (ollama-native) | memory | 2 | 1 | `no_tool_calls` | 2.39s |
Identical *behavioral* shape (one tool call, clean final answer)
on this simple task. The wall-clock delta is interesting but not
conclusive on a single run — could be cache warmth or could be
Ollama's parser overhead. A full sweep will separate signal from
noise.
## Known limitations
- **Arm C system prompt handling.** `gm.text.ToolSampler` doesn't
take a pre-populated message history cleanly, so arm C folds a
compact version of `FAKE_HISTORY` into the user message. Arms A
and B feed history through proper role-tagged turns. Fidelity
compromise — if a C vs A/B delta traces here, rebuild
`sampler.turns` directly before calling `.chat()`.
- **Arm C sampler caveat.** The deepmind-gemma `ToolSampler`
docstring notes "Gemma 1, 2 and 3 models were not specifically
trained for tool use" and flags the sampler as a proof-of-concept.
Gemma 4 *is* tool-trained, so it should do better, but if arm C
underperforms A/B the sampler implementation may be the
variable, not the model.
- **Quantization confounder.** Ollama arms run Q8 (E4B) or Q4 (26B);
arm C runs bf16. A non-trivial A vs C delta could be the
quantization. Only A ≡ B ≢ C cleanly implicates the inference
engine rather than the bits.
## Related artifacts
- `scripts/mort-bakeoff/harness.py` — the round-3 bakeoff that
established `think:false` kills 26B in multi-turn tool loops.
Task definitions are lifted from there.
- `docs/reference/bakeoff-2026-04-18.md` — round-3 writeup.
- `CORPUS_tool_calling_format.md` — the native Gemma 4 tool-call
token syntax this harness implements.
- `tooling/huggingface/model-cards/gemma-4-E4B-it-chat_template.jinja`
— the canonical template arm B renders.

"""Arm C: google-deepmind/gemma JAX ToolSampler (reference path).
This arm runs against the *canonical* JAX reference implementation. No
Ollama, no llama.cpp, no GGUF quantization, no wire protocol — the
chat template, token-level sampling, and tool-call parsing all happen
inside the Python process using the code Google wrote for Gemma 4.
**Environment requirement** — this arm cannot run inside the Ollama-only
environment used by arms A/B. Setup:
pip install jax[cuda12] gemma # or jax[cpu] for CPU fallback
huggingface-cli login # weights download via HF
It will download `gm.ckpts.CheckpointPath.GEMMA4_E4B_IT` on first run
(~8GB). Run this arm on a host with ≥16GB RAM (CPU) or ≥10GB VRAM (GPU).
**Known caveat** — the `gm.text.ToolSampler` docstring notes that
"Gemma 1, 2 and 3 models were not specifically trained for tool use"
and flags the sampler as a proof-of-concept. Gemma 4 *is* tool-trained
so it should do better here, but if this arm underperforms A/B it may
be the sampler wrapper, not the model. The trace logs the raw sampler
turns so that can be diagnosed post-hoc.

"""Native-bakeoff entry point.
Three arms, one invocation. Compares inference paths for Gemma 4:
A. ollama-json — /api/chat with JSON tools (current default)
B. ollama-native — /api/generate raw:true with canonical jinja template
C. jax-native — google-deepmind/gemma reference ToolSampler
Research question: does the inference path materially change behavior,
or is Ollama's JSON tools path faithful to the reference? If arms A and
B diverge, Ollama's parser is the variable. If B and C diverge, that's
the llama.cpp runtime / GGUF quantization / Ollama's scheduler.
Arms A and B run against a local Ollama at http://127.0.0.1:11434
by default. Arm C needs its own Python env with JAX + the `gemma`
package (see `arms/jax_native.py` module docstring).
Usage:
python3 harness.py --arm ollama-json --task movies --out runs/A/movies.json
python3 harness.py --arm ollama-native --task movies --out runs/B/movies.json
python3 harness.py --arm jax-native --task movies --out runs/C/movies.json
# Default model targets: E4B. Override with --model:
python3 harness.py --arm ollama-json --task movies --model gemma4:26b --out ...

"""Shared task definitions for the native-bakeoff.
Lifted verbatim from scripts/mort-bakeoff/harness.py so all three arms
(ollama-json, ollama-native, jax-native) see identical tasks, stubs,
system prompt, and fake history. If these ever drift, the comparison
becomes meaningless.
The goal of this harness is to isolate the *inference path* as the
only variable:
- Arm A: Ollama /api/chat with JSON `tools:[...]` (current default)
- Arm B: Ollama /api/generate with raw:true + native Gemma tokens
- Arm C: google-deepmind/gemma JAX `gm.text.ToolSampler`

SYSTEM_PROMPT = """You are Mort, a direct and witty AI assistant on Seth's Matrix server. Powered by Gemma 4. Current time: Saturday, April 18 2026 02:30 PM EDT.
When a tool can answer the question, invoke it immediately — do not narrate intent or describe what you would do. Chain tools when a single call isn't sufficient: search → fetch → synthesize. If a tool returns an error or empty results, try an alternative tool or query before answering from memory. Base your response on tool results, not your training data — cite what you found.
## Tools
- **sethsearch** — search Seth's homelab (repos, wiki, media, feeds). Use `source: "sethflix"` for movies/TV/music.
- **check_sethflix** — verify which titles are in sethflix. Pass a comma-separated list.
- **web_search** — search the internet for current information
- **chat_search** — search message history across all rooms
- **memory_read / memory_write** — recall and store durable facts about users and topics
- **web_fetch** — fetch and extract text from a URL
- **generate_image** — generate an image via SDXL.
## Boundaries
- Only persist durable facts to memory, not ephemeral chat
- You have no memory between sessions. Your context is a sliding window — older messages fall off silently. Do not claim to "remember," promise to "do better," or describe your own architecture.
