"Could not save line 'Husqvarna 578BTF backpack leaf blower' (405)" —
and nothing was written.
`/api/v1/delivery-notes/items/[id]/pricing` exports PATCH only. The
editor POSTed to it, so every save 405'd. The DN detail page has been
PATCHing the same URL correctly all along; I should have matched it
rather than assuming POST.
## Why it got through my verification
My browser check opened the editor, typed a cost, watched the totals
recompute — and stopped there. The save path is entirely separate
from the render path, and I never pressed Save, so I verified the one
half that was never broken.
Redone properly: changed a quantity 150 -> 7, pressed Save, reopened
the editor and read 7 back (the other three lines untouched at
150/150/2), then put it back to 150 so the data is as found. That is
the check that matters on these screens — display and persistence are
different code paths, and a perfectly-rendering dialog proves nothing
about either.
Suite: 3817 passing, tsc clean.
