name: Syncro — warranty work uses the "Labor- Warranty work" product, never patch a billable product to $0
description: For warranty/no-charge labor on Syncro tickets, use product_id 1049360 (Labor- Warranty work, $0/hr). Do NOT use a regular labor product with billable=false or a patched price_retail=0. Prices are determined by the product selected; never override the dollar amount to make one product behave like another.

**Rule (two parts):**

1. **Warranty / no-charge labor uses product `1049360` "Labor- Warranty work" ($0/hr, non-taxable).** Don't pick a regular Remote/Onsite/etc. labor product and try to neutralize it.

2. **Prices are set by selecting the correct product. Never change `price_retail` on a line item to make a different labor product behave like a warranty (or any other) product.** If you find yourself reaching for `update_line_item` to drop a price, that's the signal to back up and pick a different `product_id` instead.

**Why:** On 2026-05-06 (ticket #32225 Sombra Residential), I chose product `1190473` (Labor - Remote Business, $150/hr) for a follow-up warranty cleanup, set `billable: false` on the timer, and assumed the timer flag would zero the line. Syncro silently overrode `billable: false` and the resulting line came in at $75. I patched `price_retail` to $0 to "fix" it. Howard caught it: warranty work has a dedicated product in the dropdown, and patching dollar amounts is never how this is solved. The earlier guidance in `.claude/commands/syncro.md` (the "Warranty / no-charge → use closest labor product with billable=false" rule) was wrong; warranty has its own product just like Onsite, Remote, Emergency, etc., and that product is what should be used.

**How to apply:**

- **For any warranty / no-charge work:** `product_id = 1049360`, qty = actual hours, no need to patch the line — it generates at $0 because the product's `price_retail` is $0.
- **The warranty product is $0 by design — don't fake a free line with flags.** Its `price_retail` is $0, so the line generates at $0 from `price_retail` × `quantity`. Do NOT take a regular labor product and try to neutralize it with `billable: false`; that was the original mistake (see Why — and Syncro silently overrode the flag in the timer era anyway). Pick `1049360`.
- **Never reach for `update_line_item` to drop a price as a workaround.** If the dollar amount on a line is wrong, the wrong product was selected — undo, pick the correct product, redo. The only legitimate use of `update_line_item price_retail` is the Syncro auto-gen-zero recovery case (when the auto-line came in at $0 instead of the product's actual rate), and even that is a Syncro bug we're patching around, not a price-management tool.
- **For the dropdown of available labor products,** see the rate table in `.claude/commands/syncro.md`. If the situation doesn't match any of those, ask before improvising.

**Where this lands in skill code:** `.claude/commands/syncro.md` — added `1049360` to the labor product table, fixed the warranty branch in the billing workflow, and added an explicit "never patch price_retail to convert products" rule.
