Task 4 of the non-invoiceable-order-extras plan.
The page-level margin gate (process/page.tsx) short-circuits when
the item has exclude_from_invoice. An excluded line has
selling_price forced to 0 (Task 2), so the computed markup is
always -100 and the gate would wedge every extra into
approval_needed and block the order. Bypassing the gate keeps the
operational flow unblocked.
Suppressed low-margin colouring for excluded rows — a red
'-100%' chip on every extra is noise. The 'Not invoiced' badge
(T3) replaces the price chip visually.
Server-side guard in requestOrderItemMarginApproval refuses to gate
an excluded item with code 'excluded_from_invoice' (status 422).
Belt-and-braces: the MCP path can't weaponise the approval queue
to push an excluded row through manager review. Checked BEFORE
the missing_prices guard so an excluded item with selling=0 throws
the descriptive error rather than the misleading missing_prices
one.
2 tests + 1 mutation-test prove both sides of the bypass:
- excluded: throws 'excluded_from_invoice', webhook NOT fired
- non-excluded: proceeds to approval_needed, webhook DOES fire
- mutation (guard disabled): the excluded test fails
