description: Syncro prepay_hours is only reliable from GET /customers/{id}; never read it from the customer search/list endpoint

When billing in Syncro, read `prepay_hours` ONLY from the full `GET /customers/{id}` response (`.customer.prepay_hours`). The customer **search/list** endpoint (`GET /customers?query=...`) returns `prepay_hours: null` (or stale) even when the customer HAS a prepaid block. Never read prepay from a search result, and never assert "no prepaid block" / "real charge $N" in a billing preview built from search data.

**Why:** Repeated misfires — previews said "$300, no block," then the block surfaced during the invoice POST and the invoice netted $0 (block debited). Mike flagged this 2026-06-23 as a reliability problem that keeps recurring (Dataforth, Grabb & Durando #32455). The wrong figure in a preview the user confirms is the failure mode.

**How to apply:** In the billing gather step, ALWAYS `GET /customers/{id}` and pull `prepay_hours` from there BEFORE composing the preview — not just before the invoice. If you only have search/list data, fetch the full customer record first; do not guess. The /syncro skill hard rules now encode this. See [[feedback_syncro_labor_type.md]].
