User answered 8 of 9 Sprint 0.1 blocking decisions (2026-08-17); backend
ownership stays open pending a clearer re-ask. Recorded and propagated:
- Payment chain unfrozen -> BACKEND-API-REFERENCE.md §7 and the Phase 1
contract doc's status banner both updated; Phase 1/6/7 unblocked.
- No fixed external-marketplace list -> Phase 4's connector framework
respecified as config-driven/generic; Sprint 4.2 retired as "per named
marketplace," replaced with a generic onboarding runbook.
- FX rate source: ours, in-house, as the default (not just a fallback) ->
Phase 1 contract's `source` field can read "internal" as the normal case.
- VK ID before OTP -> Phase 8 sprints resequenced (VK ID now 8.2, OTP 8.3).
- Multi-seller orders: unified -> Phase 3.3, Phase 5.2, and Z16 updated to
the resolved model (one Order, per-seller Fulfillment groups).
- "Fixed 5-second payment" claim: confirmed non-issue, PAYMENT_POLL_INTERVAL_MS
is already 5000 (real polling cadence, not an artificial delay).
- API namespace: new endpoints only (/api/v2/...), no forced migration of
legacy endpoints.
- Document version: v3.1 is canonical.

- models/category.model.ts: Category -> CategoryApiModel, disambiguated
from core/categories/models/category-domain.model.ts's Category (admin
domain shape). Removes a dead unused import in item.utils.ts along the
way. Only live consumer was services/api.service.ts, updated in place.
- BACKEND-API-REFERENCE.md §5: corrected two rows documenting the
TOKEN_EXPIRED/INVALID_SIGNATURE auth-error bug as still open - the fix
(reading error.error.code before falling back to HTTP status) is
already in auth.service.ts. Doc was stale, not the code.
- Sprint 0.2 audit: AdminRole duplication and the
PRODUCT_DATA_PROVIDER/CATEGORY_REPOSITORY dead mock branches were
already resolved in a prior pass - verified, no code change needed.
- docs/backend/PHASE-1-MONEY-FX-PAYMENTS-CONTRACT.md: new wire contract
for Money/FxQuote/PriceSnapshot/payment state machine, so backend can
start Phase 1 the moment the frozen payment chain is unblocked.
