fix(bookings): adjust model reservations while a booking is out - #3063
Conversation
A model-level reservation could only be edited or cancelled on a DRAFT or RESERVED booking, and only from the Models tab inside Manage assets. Once the booking was checked out the quantity was frozen, so units that turned out to be damaged or were never collected stayed reserved for the rest of the booking — and kept counting against every other booking whose window overlapped, because availability sums outstanding requests on ONGOING and OVERDUE bookings too. Reservations are now editable for as long as the booking is live, keyed on a shared `canEditModelReservations`. The floor stays at the units already assigned: setting the quantity to exactly that count closes the reservation out and releases the rest. Cancelling still requires nothing to be assigned, because the row is the record of how those assets reached the booking. A reduction now skips the availability guard entirely. Giving units back can never need headroom, and measuring anyway refused it on a booking holding more units than the pool still contains — the case where releasing matters most. "Adjust quantity" joins the reservation row menu, opening a dialog with a one-tap "Release the N still unassigned". It reads its result from the busy → idle edge rather than from the fetcher, which keeps its last answer for as long as it is mounted and would otherwise re-show a refusal the operator already dealt with. The Models tab gains the same floor, and the menu's first item is relabelled so all three items fit on one line. Also corrects a comment claiming unassigning an asset never returns its unit: `removeAssets` decrements `fulfilledQuantity` for rows carrying the request's `bookingModelRequestId`.
…gned The model manager is already offered on ONGOING and OVERDUE bookings, where the server refused every edit, so it starts working with the change on the web side. The quantity sheet had no lower bound of its own, so an operator could enter a number below the units already assigned and only learn the floor from the server's refusal. `QuantityInputSheet` takes an optional `min` — defaulting to 1, so every other caller is unchanged — which now bounds the seed, the stepper, validity and the hint under the field. The bounds themselves come from `modelReservationBounds`, a pure helper mirroring the server's range, registered in the cross-app mirrors table.

Every decision `upsertBookingModelRequest` and `removeBookingModelRequest` make — the assigned-units floor, whether a write is a reduction, the completion stamp, and the "nothing assigned yet" cancellation guard — was taken in application code against a row read without a lock. The only lock held was on the `AssetModel` row, which assignment often never takes: `assertModelUnitsNotReservedElsewhere` skips it entirely for a write that fits inside the booking's own remaining units, and that is precisely the scan that competes here. Three consequences, all reachable under READ COMMITTED: - reducing 10/8 to 8 while a scan claims a unit leaves `fulfilledQuantity` above `quantity`. Nothing in the database forbids it, and `getAssetModelAvailability` then contributes a negative `reservedViaRequest`, offsetting other bookings' reservations and over-stating the pool; - two edits racing can leave `previousQuantity` stale, so a genuine increase is classified as a reduction and skips the availability guard altogether; - cancelling on a stale zero deletes a request whose units have just arrived, and the FK's `ON DELETE SET NULL` strips their provenance. Both functions now take a `FOR UPDATE` on the reservation row and derive everything from a read under it. The pool lock stays and is taken first, matching the order assignment takes them in, so the two paths cannot deadlock. Cancellation additionally carries its guard in the statement (`deleteMany` predicated on `fulfilledQuantity: 0`), so the invariant survives a later edit moving the lock. Also sweeps the cancel rule onto the two surfaces that missed it. The Models tab and the companion picker both offered Remove for a partially assigned reservation, which the server always refuses; both now ask `canCancelModelReservation`, and the companion row states its assigned count. Corrects the pool lock's JSDoc, which claimed every writer of a reservation row passes through it — two of the three do not.

Rather than repeat the condition a third time inline, the rule now lives in one named predicate per app — Also took your implied point about not hiding a control without a reason: the companion row now states Agreed on your severity read: the web failure was never silent (the refusal renders inline via |

The two lock-ordering tests staged a 10/8 reservation and an ONGOING booking with nothing assigned without saying why those numbers. Both are the scenario rather than incidental data — they are the states a concurrent assignment can move under the reader's feet, which is what makes the ordering assertion mean anything.
…ing to any Both reads in the raw-statement stub went through `as any` to reach the mocked resolver. `ReturnType<typeof vitest.fn>` is the pattern the rest of this file uses and says the same thing without the escape hatch, so the two eslint-disable lines go with it.

The nitpick from the review body is fixed in bc2e6ab. Both reads in the claim simulator now go through Noting for anyone reading later: this arrived as a nitpick in the review body rather than as an inline thread, which is a place automation watching only inline threads will not look.

The problem
A
BookingModelRequestreserves N units of an asset model without naming which ones. Its quantitycould only be edited or cancelled while the booking was DRAFT or RESERVED, and only from the
Models tab inside Manage assets — a place operators rarely find.
Once the booking was checked out, the quantity was frozen entirely. So a unit that turned out to be
damaged, lost, or was simply never collected stayed reserved for the rest of the booking, with no
way to hand it back. That is not only cosmetic:
getAssetModelAvailabilitysums outstandingrequests across ONGOING and OVERDUE bookings, so those units kept counting against every other
booking whose window overlapped.
Reported by a customer running book-by-model in production.
What changes
Reservations stay editable while the booking is live. Both service guards now key on a shared
canEditModelReservations(DRAFT / RESERVED / ONGOING / OVERDUE) instead of hard-coding the firsttwo. The floor is unchanged and still enforced: a reservation can never drop below the units
already assigned to the booking. Setting the quantity to exactly that count closes the reservation
out and releases everything still unassigned.
Cancelling a reservation still requires that nothing has been assigned to it — the row is the
record of how those assets reached the booking, so it is reduced rather than deleted.
A reduction skips the availability guard entirely. Giving units back can never need headroom,
and measuring anyway refused it in the case that matters most: a booking holding more units than
the pool still contains (an asset retired or taken into custody mid-booking) failed that comparison
at every quantity, leaving the operator unable to release the units they were trying to release.
"Adjust quantity" on the reservation row menu → a new
AdjustModelReservationDialog, with aone-tap "Release the N still unassigned". It reads its outcome from the busy → idle edge rather
than from
fetcher.data: a keyed fetcher keeps its last answer for as long as it is mounted, soreading it directly re-shows a refusal the operator has already dealt with. Remove is offered on
the same statuses (still only while nothing is assigned), and the menu's first item is relabelled
