# Amber Framework Knowledge Pack (demo)

The demo **knowledge pack** dataset behind
[AgentC-Consulting/knowledge-packs](https://github.com/AgentC-Consulting/knowledge-packs):
teach a small local model the [Amber web framework](https://amberframework.org) (Crystal),
and **measure** whether it learned anything with a before/after eval harness.

A *knowledge pack* compiles a body of expertise into curated sources, schema-validated
generated training JSONL, a contamination-guarded held-out eval set, and a JSON manifest.
This repo ships the exact training data and the two 50-item eval sets used for the measured
run on record ([`live-run/RESULTS.md`](https://github.com/AgentC-Consulting/knowledge-packs/blob/main/live-run/RESULTS.md)).

## What's here

```text
data/train.jsonl          471 training pairs (mlx chat format: {"messages": [...]})
data/valid.jsonl          24 validation pairs
eval/memorization.jsonl   50 items (30 MC + 20 recall) — trained-fact probe
eval/heldout_sources.jsonl 50 items (30 MC + 20 recall) — overclaiming control
eval/stats.json           generation stats (unit counts, split salt, seeds)
```

Generated deterministically (no model, no API) from
[amberframework/docs](https://github.com/amberframework/docs) @ `3648105`: 336
heading-chunked source units, split **before** generation by
`sha256(unit_id + "kp-amber-v1")` into 262 train / 74 eval units. Cloze facts are
sentences containing exactly one blankable inline-code term; each train fact yields 3
pairs (2 cloze phrasings + 1 multiple-choice phrasing).

## The two eval sets — read this before quoting numbers

- **`memorization`** probes facts that ARE in the training data through question templates
  that never appear in training. It is a **trained-fact probe measuring fact injection,
  not a source-held-out eval**.
- **`heldout_sources`** draws facts only from the 74 eval-split units, which contributed
  **zero** training examples (unit-ID exclusion + dedup of blanked sentences into train).
  It is the leakage/overclaiming control: a memorization-only adapter should NOT improve
  here. Semantic restatements of a fact worded differently inside a train unit cannot be
  fully excluded by these guards.

Measured on `mlx-community/SmolLM-135M-Instruct-4bit` (M1 Max, LoRA, lr 1e-4, 2000
iterations): recall of trained facts 1/20 → 11/20 at temp 0; the held-out-source control
stayed flat (9/50 → 7/50). Per-item reports (question, gold, full completion, verdict) are
checked in at
[`live-run/reports/`](https://github.com/AgentC-Consulting/knowledge-packs/tree/main/live-run/reports).
The eval questions are synthetic and not hand-reviewed; treat all numbers as lab notes, and
run the harness yourself — the generator and scorer are in the repo
([`live-run/`](https://github.com/AgentC-Consulting/knowledge-packs/tree/main/live-run)).

The trained adapter these numbers were measured on is published at
[crimson-knight/SmolLM-135M-Instruct-4bit-amber-lora](https://huggingface.co/crimson-knight/SmolLM-135M-Instruct-4bit-amber-lora).

## Quality ceiling (stated plainly)

Deterministic template generation tests memorization and lookup-like recall only — no
conceptual synthesis, no troubleshooting judgment. The 135M 4-bit base model is
floor-level capability; the signal is in the recall probes, not multiple choice.
