… dataset export (Spec B) ## What Adds a prodclone extractor (Spec B) — a tool that exports feature-filtered private test datasets from a production database clone into the replay-data format. Built by a Sonnet agent from SPEC_B: `scripts/prodclone_extract.py` (click CLI with `survey` and `extract` commands) over `polismath/replay/prodclone.py` (pure SQL builders, feature classifiers, CSV writers, slug minting, path-safety guard). ## Privacy invariants (reviewed) - The output path is resolved and asserted to live under `real_data/.local/` (refuses anything else). - The directory prefix is a salted sha256 of the zid (the internal conversation id), never a real report id. - The comment-body column is present but ALWAYS empty (text redacted — the math pipeline never reads it). - The slug-to-zid map lives only in `.local/prodclone_map.json` (merge-updated). The export mirrors the public dataset byte-layout: votes carry the full revote history (`ORDER BY created, ctid` — no dedup); comment agrees/disagrees are counted over all vote rows the way `report.ts` does. ## Feature classes modheavy / revote / banned (voters with `participants.mod = -1`) / meta / zerovote / smallmix / midmix (unremarkable-volume coverage). ## Testing 52 passed — pure-function units (no DB) plus one integration test on the repo's `require_polis_postgres` throwaway-Postgres fixture, round-tripping survey → extract → `load_export_votes`. TDD (RED commit first in the agent's clone). commit-id:9f45b733
