Root-cause fix for cross-file DB pollution in the vitest suite, which
surfaced as intermittent FK-violation failures once the suite hit 12
test files. tests/setup.ts previously mutated the global
process.env.DATABASE_URL and relied on src/lib/prisma.ts's singleton
picking it up, which is racy across files sharing a worker process
(process.env isn't reset between files even though Vitest resets each
file's module registry). fileParallelism: false only masked this.
Now each test file's own tests/setup.ts creates its own throwaway
Postgres database and vi.mock()s "@/lib/prisma" with a dedicated
PrismaClient constructed via the explicit datasourceUrl option, so no
mutable state is shared between files and fileParallelism can go back
to its default (true).
Verified with 4 consecutive full `npm test` runs (327/327 passing each
time) and no leftover throwaway databases after each run.
createMaintenanceRecord()'s AssetItem status guard pinned status:{not:"retired"}
instead of status:"in_stock", so two concurrent opens (or an open racing a
concurrent createAssignment()) could both pass the guard, producing two open
MaintenanceRecords or an orphaned active Assignment. Guard now pins "in_stock"
exactly, mirroring createAssignment()'s own atomic guard.
closeMaintenanceRecord()'s targetStatus accepted any of the 4 AssetItemStatus
values, including "assigned" — which sets AssetItem.status without creating a
corresponding Assignment row, desyncing Assignment (source of truth for who
holds what) from AssetItem.status with no way back. Restricted to
in_stock|retired, the only two outcomes a closed repair can actually resolve
to.
createMaintenanceRecord() opens a record and flips AssetItem.status to
"repair" inside one transaction, rejecting on missing/retired AssetItem,
an active Assignment, or an already-open record for the same item.
closeMaintenanceRecord() sets endDate/resolutionNotes and applies a
caller-supplied targetStatus (never defaulted) to the AssetItem, guarding
double-close and endDate>=startDate. Mirrors src/lib/assignments.ts's
Zod-validate + $transaction + WHERE-guarded updateMany race-closing pattern.
New entity tracking repair/warranty/preventive maintenance jobs for an
AssetItem. Reuses Vendor (nullable) for the repair location, no cost
field (mirrors PurchaseOrder). "At most 1 open record per AssetItem"
invariant left to the application layer, mirroring Assignment.
Entity mới track sửa chữa/bảo hành cho AssetItem, hiện thực hoá case
"in repair" đã note từ trước. Field, type enum, đồng bộ AssetItem.status,
và quyết định không track cost đều đã chốt với stakeholder — sẵn sàng

Condensed the "Trạng thái hiện tại"/"Việc còn dở" sections — most of the
detailed per-entity narrative was either resolved, superseded by a later
change, or derivable from git log, so it's trimmed to what isn't:
decisions, gotchas, and still-open risks. Added the UI (worktree-ui-basic
merge), the Assignment transfer fix, and the two dormant findings
(XOR defense-in-depth, Assignment FK onDelete) from the code-reviewer gate.
Vitest's default glob isn't excluded for .claude/, so a sibling worktree
under .claude/worktrees/ (e.g. worktree-ui-basic) got silently collected
and run against this repo's current src/ via the "@" alias, doubling the
test count and running a stale test file against current code under a
shared identity. Found by an independent test-runner pass while verifying
the Assignment transfer fix.
The only way to move an Assignment to a new employee was two separate calls
(PATCH return + POST create), which is not atomic and left a race window
where a third party could grab the now-in_stock AssetItem in between, plus
no rollback if the second call failed. Adds transferAssignment() which
closes the old Assignment and creates the new one inside a single
prisma.$transaction(), per docs/asset-license-management.md's "Assignment
(chốt 2026-08-02)" spec. Does not touch AssetItem.status or
License.seatsUsed — the resource never becomes free mid-transfer. Wired
into PATCH /api/assignments/[id]: an employeeId key in the body dispatches
to transfer, a returnedAt key to return, both together is rejected as
mutually exclusive.
48 tests covering the XOR validation, the AssetItem.status/active-assignment
preconditions, seat overbooking, seat/status sync across assign+return,
FK-not-found for all three FKs, double-return, 404s, auth-gating, malformed
bodies, and two explicit concurrency tests (Promise.all against a
1-remaining-seat License and against a single in_stock AssetItem) exercising
the transaction race-closing logic in src/lib/assignments.ts.
POST/GET /api/assignments mirror the existing entity route pattern
(auth-gated, thin handler delegating to src/lib/assignments.ts). PATCH
/api/assignments/[id] is the first dynamic-segment route in the codebase,
per the stakeholder-confirmed convention (docs/asset-license-management.md)
of update routes being PATCH /api/<entity>/[id] rather than an
action-based sub-route.
createAssignment() enforces the XOR (assetItemId/licenseId) at the Zod
layer and the AssetItem.status/License.seatsUsed business rules inside a
single prisma.$transaction(), using atomic WHERE-guarded updateMany() calls
(not plain read-then-write) to close the seat-overbooking and
double-assignment race conditions flagged for License by code-reviewer.
returnAssignment() reverses those side-effects the same way and closes the
double-return race with the same pattern.
Links Employee to exactly one of AssetItem/License (XOR enforced at the
Zod layer, not built yet) via nullable FKs, plus assignedAt/returnedAt/
signedAt timestamps. See docs/asset-license-management.md's "Assignment"
section for the full spec.
Retrofit AssetItem.model (string) -> modelId (FK to AssetModel) —
closes out Lane B (AssetCategory -> AssetCategoryAttributeDef +
AssetModel -> dynamic specs validation -> AssetItem.modelId).
Verified green by test-runner (225/225 tests, tsc/lint/build clean)
before merge.
Co-Authored-By: Claude Sonnet 5 <[email protected]>
AssetItem.model was a free-text string with no referential integrity.
Now a required FK to AssetModel, mirroring the Request.employeeId and
License.vendorId retrofit precedent (no backfill needed, no real
AssetItem data existed).
Wire dynamic specs validation into AssetModel creation: builds a
runtime Zod schema from the category's AssetCategoryAttributeDef
rows, rejects unknown keys, enforces required keys. Verified green
by test-runner (223/223 tests, tsc/lint/build clean) before merge.

AssetModel entity: Prisma model+migration, Zod+CRUD (categoryId FK
+ business rule requiring valueGroup=high_value, specs JSONB loosely
validated for now), API routes, tests. Verified green by test-runner
(217/217 tests, tsc/lint/build clean) before merge.
Co-Authored-By: Claude Sonnet 5 <[email protected]>
28 tests covering lib-level validation/CRUD and route-level HTTP behavior:
malformed JSON, non-object body, invalid dataType, categoryId FK violation,
duplicate (categoryId, key) rejected with a clean 400 (not 500), and same
key allowed across two different categories (the "not globally unique"
case), plus auth gating.
Zod schema + validate function, Prisma-backed CRUD following the
{ok,value}|{ok,error} pattern from the start. createAssetCategoryAttributeDef()
catches P2002 for the composite (categoryId, key) unique constraint (mirrors
createAssetItem()'s serialNumber handling) and P2003 for the categoryId FK
(mirrors createPurchaseOrder()).
Per-category dynamic attribute definitions (key/label/dataType/required/
sortOrder), FK to AssetCategory, composite unique (categoryId, key) so the
same key is allowed across different categories but not duplicated within
one. dataType is a new closed Prisma enum (AssetAttributeDataType), a
dev-defined technical set distinct from AssetCategoryValueGroup.
Add nullable Request.purchaseOrderId FK (demand-side PO
traceability) — closes out Lane A (Vendor -> License.vendorId ->
PurchaseOrder -> purchaseOrderId x3). Verified green by test-runner
(143/143 tests, tsc/lint/build clean) before merge.

Add nullable License.purchaseOrderId FK (supply-side PO
traceability). Verified green by test-runner (139/139 tests,
tsc/lint/build clean) before merge.
Co-Authored-By: Claude Sonnet 5 <[email protected]>
Nullable FK from License to PurchaseOrder for supply-side traceability
(which PO a license came in through), mirroring AssetItem.purchaseOrderId's
just-merged pattern exactly. Separate commit from the earlier
License.vendorId retrofit per the project's 1-commit-per-business-change
convention.
Add nullable AssetItem.purchaseOrderId FK (supply-side PO
traceability). Verified green by test-runner (131/131 tests,

PurchaseOrder entity: Prisma model+migration, Zod+CRUD (P2003 on both
vendorId/receivedById, receivedAt/receivedById co-nullability
refine), API routes, tests. Verified green by test-runner (127/127
tests, tsc/lint/build clean) before merge.
