sdarbinyan 86091a4742 feat(sellers): typed domain models for future Seller Management - no logic, no API, no auth changes

Typed models only, per mission. Nothing outside the new files reads
or writes any of this yet.

New core/sellers/models/ (mirrors core/products/models,
core/auth/models convention):
- MarketplaceRef - minimal {id,slug,name} reference from a seller
  back to its marketplace, distinct from bootstrap's TenantConfig.
- SellerStatus - 'pending'|'active'|'suspended'|'disabled', no
  transition logic.
- SellerScope - {sellerId, marketplaceId}, domain-level counterpart
  to BootstrapConfig.seller (SellerConfig from the ADR-011 pass).
- SellerBranding (+SellerContact/SellerAddress/SellerThemeOverrides)
  - logo/banner/description/contacts/address/theme overrides, every
    field optional. Marketplace branding/theme remain default;
    nothing consumes this yet.
- SellerPermissionRole/SellerPermissions - marketplaceOwner/seller/
  sellerStaff/platformAdmin. Separate vocabulary from the existing
  AdminRole (core/auth/models/permission.model.ts) - not merged, not
  wired into any guard, zero auth behavior change.
- Seller - the eventual entity, composed from the above.

Changed (optional-only, verified backward compatible):
- Item (models/item.model.ts) gained sellerId?: string
- AdminProduct (features/admin/products/models/) gained
  sellerId?: string
- AdminOrder (features/admin/orders/models/) gained sellerId?: string

Absent means marketplace-owned in every case, exactly like every
existing product/order today. No consumer of any of these three
models needed updating. AdminOrderItem (per-line-item ownership) and
the existing PermissionsConfig/AdminRole system were deliberately not
touched - out of scope for this pass.

Added docs/architecture/foundation/Seller-Management-Domain-Models.md
documenting every new type, every changed field, and the explicit
non-goals list. Linked from the foundation README alongside ADR-011
and the diagrams doc.

tsc --noEmit clean, arch:check (boundaries + cycles) clean.

Marketplace Platform Architecture Foundation

Status: Approved Owner: Lead Software Architect Date: 2026-07-03

Purpose

This folder defines the mandatory engineering governance for transforming this codebase into a reusable, configuration-driven, multi-tenant Marketplace Platform (Marketplace-as-a-Service).

This repository is not treated as a single marketplace website. It is a platform runtime that must support unlimited tenants from one Angular application.

Platform Principles

One codebase, unlimited tenants.
Every tenant has three surfaces: Website, Builder, Backoffice.
Frontend contains no tenant-specific implementation code.
Tenant behavior is controlled by configuration loaded at bootstrap.
Authentication, payment, authorization behavior and contracts remain unchanged.
Prefer composition over inheritance.
Prefer configuration over conditionals.
No circular dependencies.
Shared and UI layers are feature-agnostic.

Non-Negotiable Constraints

Authentication behavior remains exactly as current implementation.
Payment API behavior remains exactly as current implementation.
Authorization behavior remains exactly as current implementation.
Existing authentication and payment API contracts cannot be changed.
Proven modules are reused, wrapped, and isolated, not redesigned.

Document Set

Architecture Decision Records

Seller Management (optional, in preparation — not built)

ADR-011 — decision record
Seller-Management-Diagrams.md — hierarchy, bootstrap gate, type diagram
Seller-Management-Domain-Models.md — typed models, optional sellerId fields

Engineering Rule Documents

Compliance

All new work must comply with this foundation. If an implementation conflicts with these rules, implementation must be adjusted. If a rule must change, an ADR update is required first.

Sprint 11.5 Standardization Audit (2026-07-09)

Platform-wide standardization was executed before Admin Platform work.

Completed Standardization

Verified and enforced container/facade/domain/infrastructure boundaries across active website features.
Removed remaining legacy variant naming in application-layer templates/styles.
Removed duplicate legacy search-history implementation in catalog feature module.
Standardized design-token surface with explicit spacing, radius, shadow, and transition tokens.
Added widget metadata support for title/subtitle/visibility/layout/animation/style/permissions in shared contracts and dynamic rendering path.
Converted remaining identified hardcoded UI strings in audited runtime pages/components to translation keys.

Bootstrap/Configuration Gaps Identified

Widget permission model supports auth gating but role/permission enforcement is limited by current auth session shape (no role list in session model).
Popular search defaults are currently facade-local and should be moved to bootstrap-configurable catalog search settings.
Storage key naming conventions for local persistence are platform-scoped but still static constants; optional bootstrap override could improve tenant isolation.

Validation Baseline

Build and architecture checks are required for acceptance of this sprint.
Final details and file-level changes are tracked in Platform-Standardization-Report.md.

Mandatory Phase Order

Implementation must proceed only in this order:

Foundation structure only, app compiles.
Shared interfaces and types only.
Mocked configuration payloads only.
ConfigService abstraction only.
Theme engine.
Dynamic rendering engine.
Reusable widget library.
Website from configuration.
Builder from configuration domain.
Backoffice from business domain.
Backend documentation.

For each phase:

Explain what will be created.
Explain why.
List files to create.
Explain dependencies.
Implement only that phase.
Verify build integrity.
Stop and wait.
