Showcase / question: a board-proven offline language runtime on ESP32-C3, and whether this points to a more extreme form of language/runtime co-design

Hi gemma.cpp folks,

I wanted to share a small but unusual language-runtime project that may be relevant to the kind of language/runtime co-design boundary this repo is already exploring.

We built a public demo line called Engram and deployed it on a commodity ESP32-C3.

Current public numbers:

* Host-side benchmark capability
* `LogiQA = 0.392523`
* `IFEval = 0.780037`

* Published board proof
* `LogiQA 642 = 249 / 642 = 0.3878504672897196`
* `host_full_match = 642 / 642`
* runtime artifact size = `1,380,771 bytes`

Important scope note:

This is **not** presented as unrestricted open-input native LLM generation on MCU.

The board-side path is closer to a flash-resident, table-driven runtime with:

* packed token weights
* hashed lookup structures
* fixed compiled probe batches
* streaming fold / checksum style execution over precompiled structures

So this is not a standard lightweight dense inference runtime on a small device. It is closer to a task-specialized language runtime whose behavior has been crystallized into a compact executable form under very severe physical constraints.

Why I’m posting here is that gemma.cpp seems to sit at an interesting point between research-friendly implementation, low-level execution, and simplified language inference systems.

What I’d be curious about is whether systems like this should be thought of as:

* outside the normal lightweight inference-runtime family
* an extreme endpoint of language/runtime co-design
* or an early sign that some language-task capability may eventually be deployed in more specialized executable forms than even a minimalist dense runtime

If this direction is relevant to your team, I’d be glad to compare notes.
