Release gate and training spine

Evaluation, retraining, and the pipeline that decides what ships.

DueCare ships nothing without an evaluation pass. Every pack release runs a regression suite. Every adapter retrain runs a comparison set against the previous adapter. The A07 Kaggle notebook turns Persona + GREP + RAG + Tools traces into SFT data and DPO preference pairs, then re-benchmarks before any model artifact is published.

01 · Lifecycle

Six stages, one direction.

Nothing skips a stage. A failed stage either bounces back to revision or rejects the candidate.

Collect

Pull public-source updates from the research monitor. Pull reviewed partner submissions. Pull evaluation-pack proposals from researchers.

Curate

Curators review proposals, attach citations, and shape pack-diffs or new evaluation cases.

Train

Optional: run A07 to train a corridor LoRA adapter with SFT, then DPO over harness-on vs. raw-Gemma answers. Base Gemma 4 weights never change.

Evaluation

Run the regression suite + new cases against the candidate adapter / pack. Compare to last vetted release.

Approve

If evaluation passes, curators approve the pack and / or adapter release. Old approvals remain in the public log.

Publish

Append-only release to the hub. Audit row emitted. Subscribers on the “Pack updates” topic notified.

One regression on stale.citation.detect: candidate is more permissive than 1.3.0 with citations older than 18 months. Curator review queued; release blocked until fixed or explicitly waived.

03 · The evaluation suites

Six categories. All public.

Every case is a pack-versioned JSON object with a fixed input, an expected behaviour, and a citation rule. Researchers can pull and run the same suite locally.

Suite 01

Citation

Does the harness anchor every claim to the correct pack citation? Does it refuse when no citation exists?

Suite 02

Detection

Does the harness correctly identify patterns it should: fee requests, passport handling, identity mismatch?

Suite 03

Refusal

Does the harness refuse where it should: legal advice, emergency action, anything outside the pack?

Suite 04

Tool call

Are tool calls well-formed? Do they hit the right tool with valid arguments? Do they handle tool errors?

Suite 05

Translation

Are corridor-language responses faithful, idiomatic, and numerically correct?

Suite 06

Adversarial

Source poisoning, prompt injection, citation laundering. Cases authored by partners and external researchers.

04 · Retraining policy

What we retrain. What we don’t. When.

DueCare does not retrain Gemma 4 base weights. We train two named LoRA adapters on top — SafetyJudge (anti-exploitation reasoning, trained by A-07 bench-and-tune via Unsloth SFT + DPO) and PrivacyRedactor (PII anonymization for the local-intake path, trained by A-12 pii-fine-tune-eval). Both train on curated public, synthetic, composite, or anonymized data. Never on raw worker chats or raw case content.

05 · Training data ladder

How harness behavior becomes model behavior.

RAG, GREP, tools, and persona responses are useful training signals only after they become approved examples. The public claim is SFT + preference optimization, not a hidden RL loop.

SFT

Harness-distilled targets

Run an approved prompt through Persona + GREP + RAG + Tools. Store the bare prompt as the user turn and the cited harness answer as the assistant target.

DPO

Chosen vs. rejected pairs

Use the harness-on answer as chosen and the raw Gemma answer as rejected. This is the first preference-training path before any PPO/GRPO-style RL is added.

Gate

Only publish if it survives evaluation

A07 re-runs stock, SFT, and DPO variants. A11 regenerates harness-lift reports. Any PII leak, citation regression, or unsafe-help increase blocks release.

06 · Reproduce a release

Same weights. Same packs. Same evaluation suite.

Pull the vetted pack, pull the matching adapter, run the evaluation suite locally, or rerun A07 on Kaggle with the same git SHA and dataset version. Mismatches against the published numbers are bug reports.
