## SWE-chat v2 import (gated source)
The SWE-chat source is not downloaded by this repository. After accepting the dataset's
Hugging Face conditions, place a **pinned** Parquet snapshot below the ignored
`.artifacts/swe-chat/raw/` directory, record its immutable revision, then run the
streaming extractor. It reads only the needed columns, takes the first three qualifying
human prompts per session, and writes the first prompt plus hashes for the two context
turns. Do not use `main` as a revision.
```bash
ml/purpose-classifier/.venv/bin/pip install -r \
ml/purpose-classifier/requirements-swe-chat.txt
ml/purpose-classifier/.venv/bin/python \
ml/purpose-classifier/export_swe_chat.py \
--revision <accepted-immutable-hf-revision>
```
The export and manifest remain ignored because candidate JSONL temporarily contains all
three messages. Run the one-record schema/availability canary before the 100-session dry
run; both use Luna through subscription-backed `codex exec`, not an API key. The labeler
writes only the first message to canonical source JSONL; state and audit sidecars retain
the other turns solely as hashes and source IDs.
```bash
ml/purpose-classifier/.venv/bin/python \
ml/purpose-classifier/label_swe_chat_prompts.py --limit-sessions 1
ml/purpose-classifier/.venv/bin/python \
ml/purpose-classifier/label_swe_chat_prompts.py --limit-sessions 100
```
Use a fresh `--output` path for the dry run, then manually audit it before invoking the
full resumable run. Cases marked `recoverableFromFirst=false` remain `vague-eval`
abstention evidence and are excluded from optimization.

"""Export three-turn SWE-chat candidates without retaining later-turn text.
The source snapshot is gated and deliberately stays below ``.artifacts/``. This
importer does not download it: callers supply an already accepted, revision-pinned
Parquet snapshot. It reads Parquet in record batches, joins the small sessions table
only for repository/user grouping, and writes an unlabeled JSONL that contains the
first prompt plus hashes (never text) for the two teacher-context prompts.

frontendImpl (UI/styling), quickFix (known small change), refactor (behavior-preserving
restructure), debugging (unknown cause/failure), review (explain/audit existing work), and
writing (docs/prose). Planning wins over implementation; docs about code are writing;
known small changes are quickFix while unknown failures are debugging. mixed is true iff
secondary is non-null, and then slice=mixed. Keep plausible terse/ambiguous prompts; reject
only junk, scaffolding, obvious assistant content, or non-technical material.
Set recoverableFromFirst=true when the primary label is knowable from first_message alone.
Set it false when later context is required. For false, retain the record but set slice to
vague-eval: it is abstention evidence, never training data. For junk set it null and every
label field null. difficulty is 0..1; lang is a BCP-47 tag.
