Phase 6b of the SHOC-alignment plan — client side of the optimistic-concurrency
wire contract shipped in 6a.
shared/api-contracts (additive):
- rowVersion: string on ProposalListItem, ProposalDetail, and LineItem
- proposalVersion?: string on UpdateProposalRequest and
BulkUpdateLineItemsRequest; new ProposalVersionRequest
- ConcurrencyConflict<T> { message, currentState } — the SHOC ADR 0004
409 envelope (guarded path; the unguarded fallback carries no state)
- matching zod schemas, all kept under the satisfies z.ZodType<T> coupling
web:
- lib/api/errors.ts: ConflictError carrying the server's reloaded
currentState; client.ts interceptor throws it on 409 (WEB-M2 401
handling untouched)
- guarded mutations read the token from the cached proposal detail at
mutate time; the save flow chains rotated tokens (PUT response token
into the bulk replace) and ends with a detail refetch so
approve-after-save never sends a stale version
- 409 recovery in the admin use-cases: write currentState into the
detail cache, invalidateProposalViews() (stale-queue invariant holds
on the failure path too), and toast the conflict instead of the
generic failure message
- e2e smoke mock payloads carry rowVersion; vitest coverage for the
interceptor ConflictError paths, token threading/rotation, and 409
cache recovery
Verified: shared typecheck, web tsc/vitest (69)/build/prettier/Playwright
smoke, mobile tsc (create-only, no changes needed).
