name: Syncro — use add_line_item for billing, not timers
description: Syncro billing uses add_line_item directly. Timer workflow (timer_entry → charge_timer_entry) is not used. Overrides previous rule about timers being required.

**Rule:** Bill Syncro tickets with `POST /tickets/{id}/add_line_item` directly. Do NOT use `timer_entry → charge_timer_entry`.

**Why:** Mike confirmed 2026-05-21 that the timer workflow is not used. The previous rule requiring timers was wrong and caused repeated billing failures (wrong product on the timer, product_id silently ignored by charge_timer_entry, etc.).

**How to apply:**

- `add_line_item` is the billing path for all work: labor, warranty, internal, hardware.
- Set `product_id`, `quantity` (decimal hours), `price_retail` (fetched live), `name`, `description`, `taxable: false`.
- Do not create timer entries as part of billing.
- Timer endpoints still exist in Syncro but are not part of the ACG billing workflow.

**Previous rule (SUPERSEDED):** "All work-time billing MUST go through timer_entry → charge_timer_entry." That rule is no longer in effect as of 2026-05-21.
