Two new B2B roles for CĐT (project developers) and KCN operators, provisioned by
admin. Each account owns a subset of ProjectDevelopment / IndustrialPark records
and can CRUD them from the dashboard; admin retains full access.
Phase 1 — Schema
- Extend UserRole enum with DEVELOPER + PARK_OPERATOR (before ADMIN)
- ProjectDevelopment.ownerId FK (User, ON DELETE SET NULL) + index
- IndustrialPark.ownerId FK + index
- Migration 20260420030000
Phase 2a — Backend authorization
- CreateProjectCommand + CreateIndustrialParkCommand accept ownerId; controllers
auto-set it to the caller's user id when role=DEVELOPER / PARK_OPERATOR
- Update + Delete commands gain (requesterUserId, requesterRole) and enforce
ADMIN-or-owner via ForbiddenException; reassigning ownerId is admin-only
- Search params gain optional ownerId filter wired through Prisma repos
- New endpoints: GET /projects/mine/list, GET /industrial/parks/mine/list
- user-rate-limit guard: add DEVELOPER + PARK_OPERATOR entries (300/window)
Phase 2b — Admin provision
- ProvisionDeveloperCommand/Handler: create user (role=DEVELOPER), pre-validate
target projects have no existing owner, batch-assign ownerId
- ProvisionParkOperatorCommand/Handler: same for PARK_OPERATOR + IndustrialPark
- POST /admin/accounts/developers, POST /admin/accounts/park-operators (admin-only)
- DTOs with phone/password/fullName/email + optional {project,park}Ids[]
Phase 2c — Project stats for developer dashboard
- GetProjectStatsQuery + handler: aggregates linkedListingCount, activeListingCount,
totalInquiries, unreadInquiries, savedByUsers via Property → Listing → Inquiry chain
- GET /projects/:id/stats — admin sees all, DEVELOPER only their own (403 otherwise)
Phase 3 — Frontend
- Dashboard layout role-aware: DEVELOPER sees "Dự án của tôi" + CRM + Profile (hides
listings/analytics/subscription); PARK_OPERATOR sees "KCN của tôi" equivalent
- /projects dashboard page switches to duAnApi.searchMine() when role=DEVELOPER
- /industrial-parks page switches to industrialApi.searchMine() when role=PARK_OPERATOR
- Admin nav gains "Tài khoản CĐT" + "Tài khoản KCN" entries
- New pages /admin/accounts/developers + /admin/accounts/park-operators with
checkbox-based multi-select for linking entities
- adminApi.provisionDeveloper + provisionParkOperator + types
- duAnApi.searchMine + getStats; industrialApi.searchMine
- Login demo accounts list includes CĐT Vingroup + KCN VSIP
Phase 4 — Seed (prisma/seed-b2b-accounts.ts)
- DEVELOPER "CĐT Vingroup" (+84912000001) owns 4 projects
- DEVELOPER "CĐT Masterise Homes" (+84912000003) owns 2 projects
- PARK_OPERATOR "Vận hành KCN VSIP" (+84912000002) owns 2 seeded KCN
- Password Velik@2026 for all

Foundation for Phase E (AI advisor / AI valuation on listing detail).
An admin sets the Anthropic Claude credentials once in the new
"/admin/settings/ai" page; downstream features read them via
SystemSettingsService.
Database
--------
- New Prisma model SystemSetting { key @id, value Text, valueType,
isSecret, updatedAt, updatedBy }. db:push applied cleanly.
Backend
-------
- SystemSettingsService — canonical getter/setter for
ai.api_url / ai.api_key / ai.model. maskApiKey() returns the last 4
chars prefixed with "sk-ant-...". Exposes unmasked getAiSettings()
for server-side consumers (AI advisor handlers).
- GET /admin/settings/ai — returns { apiUrl, apiKeyMasked, model,
hasApiKey, updatedAt }. Never emits the raw key.
- PATCH /admin/settings/ai — body accepts partial { apiUrl, apiKey,
model }. apiKey sentinel "__UNCHANGED__" preserves the stored value;
empty string clears it; any other value overwrites.
- CQRS: get-ai-settings query + update-ai-settings command. Registered
in admin.module.ts; service exported via modules/admin/index.ts so
Phase E can inject it.
Frontend
--------
- adminApi.getAiSettings() / updateAiSettings() added to
lib/admin-api.ts with shared AiSettings + UpdateAiSettingsPayload
types.
- New Lucide-only nav entry "Cài đặt AI" (Sparkles) in admin layout.
- /admin/settings/ai/page.tsx — Card with API URL input, masked API
key input with Eye/EyeOff toggle, "Xoá key" button, model Select
(claude-opus-4-5 / sonnet-4-5 / haiku-4-5 + custom input), save
button with inline success/error banners, "last updated" timestamp.
- i18n keys adminNav.settings + adminNav.aiSettings in vi.json/en.json.
Constraints
-----------
- No new packages. Runtime imports for NestJS-DI classes preserved.
- Key NOT encrypted at rest (MVP); documented in service comment as
future hardening.
- Page inherits existing admin auth guard via (admin) layout.
Verification
------------
- API typecheck clean.
- Web typecheck clean in touched files.
- API suite: 1975 / 1975 pass.

Create a single `currency.ts` utility with `formatPrice`, `formatVND`,
`formatPricePerM2`, and `parseVND` to replace 9+ duplicated inline
formatters. This fixes inconsistent decimal handling (1.5M was truncated
to "1 triệu") and standardises price/m² display. Integrated across
property cards, listing detail, dashboard, analytics, payments, pricing,
and admin moderation pages with 19 new unit tests.
