-- Hard-delete leftover v1-process-smoke EANs (8700999...) from Platform Demo only.
--
-- There is no product soft-delete HTTP API (products are GET/PATCH only).
-- This script is the safe admin/ops path for Demo cleanup.
--
-- NEVER touches A1 Slovenija (or A1 cohort aliases). Refuses if the resolved
-- target is missing, ambiguous, or looks like A1.
--
-- Usage (PowerShell):
--   psql $env:DATABASE_URL -v ON_ERROR_STOP=1 -f scripts/cleanup-process-smoke-eans.sql
--
-- Preview only (no deletes):
--   SELECT c.name, r.gtin FROM raw_products r
--   JOIN companies c ON c.id = r.company_id
--   WHERE lower(c.name) = 'platform demo' AND r.gtin LIKE '8700999%';
--
-- Go path: cd apps/api && go run ./cmd/seed-demo -purge-smoke-eans
-- Related: scripts/v1-process-smoke, docs/safe-test-fixtures.md
