Backfill Tiers — PAUSED

Do not run this backfill. The buttons below are disabled.

What happened:

• The original real-run timed out at Vercel's 300s cap after tagging ~501 of 5,100 products.
• Catalog turned out to be 5,100+ products (mostly BookCloud dropship), not the ~400 originally estimated.
• Strategic decision: tier tags are analytics-only. Storefront templates do not read tier-* tags.

Why this is fine:

• tier-originals (2 products) and tier-curated (24 products) are at 100% coverage — these are the tags used for indie/Direct author promotions and sales.
• tier-mainstream is at 501/5,100, but that's only relevant if we ever need "explicitly mainstream" queries. We don't.
• Forward-looking patches (1A/1B) keep auto-tagging tier-originals on every new Direct submission.

If full coverage is ever needed: redesign with batching (Vercel 300s cap × ~50ms per tagsAdd mutation × 5,100 products = no margin). See handoff doc for Approach A/B options.
