Add OnboardingProviderProtocol so modules declare their own post-signup
onboarding steps. The core OnboardingAggregator discovers enabled
providers and exposes a dashboard API (GET /dashboard/onboarding).
A session-scoped banner on the store dashboard shows a checklist that
guides merchants through setup without blocking signup.
Signup is simplified from 4 steps to 3 (Plan → Account → Payment):
store creation is merged into account creation, store language is
captured from the user's browsing language, and platform-specific
template branching is removed.
Includes 47 unit and integration tests covering all new providers,
the aggregator, the API endpoint, and the signup service changes.

Move core signup service from marketplace to billing module, add
automatic Stripe product/price sync for tiers, create loyalty-specific
signup wizard, and enforce that platform is always explicitly known
(no silent defaulting to primary/hardcoded ID).
Key changes:
- New billing SignupService with separated account/store creation steps
- Stripe auto-sync on tier create/update (new prices, archive old)
- Loyalty signup template (Plan → Account → Store → Payment)
- platform_code is now required throughout the signup flow
- Pricing/signup pages return 404 if platform not detected
- OMS-specific logic (Letzshop claiming) stays in marketplace module
- Bootstrap script: scripts/seed/sync_stripe_products.py

All route files (admin.py, store.py) now export `router` instead of
`admin_router`/`store_router`. Consumer code (definition.py, __init__.py)
imports as `router as admin_router` where distinction is needed.
ModuleDefinition fields remain admin_router/store_router.
64 files changed across all modules. Architecture rules, docs, and
migration plan updated. Added noqa:API001 support to validator for
pre-existing raw dict endpoints now visible with standardized router name.
All 1114 tests pass.

Enforce MOD-025/MOD-026 rules: zero top-level cross-module model imports
remain in any service file. All 66 files migrated using deferred import
patterns (method-body, _get_model() helpers, instance-cached self._Model)
and new cross-module service methods in tenancy. Documentation updated
with Pattern 6 (deferred imports), migration plan marked complete, and
violations status reflects 84→0 service-layer violations.

Move all auth schemas (UserContext, UserLogin, LoginResponse, etc.) from
legacy models/schema/auth.py to app/modules/tenancy/schemas/auth.py per
MOD-019. Update 84 import sites across 14 modules. Legacy file now
re-exports for backwards compatibility.
Add missing tenancy service methods for cross-module consumers:
- merchant_service.get_merchant_by_owner_id()

Double-mount store routes at /store/* and /store/{store_code}/* so the
same handlers work in dev path-based, prod path-based, prod subdomain,
and prod custom-domain modes. Wire StorePlatform.custom_subdomain into
StoreContextMiddleware for per-platform subdomain overrides. Add admin
custom-domain management UI, fix stale /shop/ reset link, add

Replace # noqa: SVC-006 with # SVC-006 to avoid ruff warnings about
unknown codes. Updated architecture validators to match the new format
by checking for the code string directly instead of the noqa: prefix.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Reverts the noqa: removal — the architecture validators (SVC-006,
SEC-034, MOD-004, API-007) use these to skip known-safe violations.
Added ruff lint.external config so ruff treats them as valid codes.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Ruff only accepts standard rule codes (e.g., E712, F401) in noqa
directives. Custom architecture validator codes (SEC-034, SVC-006,

The old migration chain was broken (downgrade path through vendor->merchant
rename made rollbacks impossible). This squashes everything into fresh
per-module migrations with zero schema drift, verified by autogenerate.
Changes:
- Replace 75 accumulated migrations with 12 per-module initial migrations
(core, billing, catalog, marketplace, cms, customers, orders, inventory,
cart, messaging, loyalty, dev_tools) in a linear chain
- Fix make db-reset to use SQL DROP SCHEMA instead of alembic downgrade base
- Enable migration autodiscovery for all modules (migrations_path in definitions)
- Rewrite alembic/env.py to import all 75 model tables across 13 modules
- Fix AdminNotification import (was incorrectly from tenancy, now from messaging)
- Update squash_migrations.py to handle all module migration directories

Add protocol-based widget system following the MetricsProvider pattern:
- Create DashboardWidgetProviderProtocol in contracts/widgets.py
- Add WidgetAggregatorService in core to discover and aggregate widgets
- Implement MarketplaceWidgetProvider for recent_imports widget
- Implement TenancyWidgetProvider for recent_vendors widget
- Update admin dashboard to use widget_aggregator
- Add widget_provider field to ModuleDefinition
Architecture documentation:
- Add widget-provider-pattern.md with implementation guide
- Add cross-module-import-rules.md enforcing core/optional separation
- Update module-system.md with widget_provider and import rules
This enables modules to provide rich dashboard widgets without core modules
importing from optional modules, maintaining true module independence.

This commit introduces a protocol-based metrics architecture that allows
each module to provide its own statistics for dashboards without creating
cross-module dependencies.
Key changes:
- Add MetricsProviderProtocol and MetricValue dataclass in contracts module
- Add StatsAggregatorService in core module that discovers and aggregates
metrics from all enabled modules
- Implement metrics providers for all modules:
- tenancy: vendor/user counts, team members, domains
- customers: customer counts
- cms: pages, media files
- catalog: products
- inventory: stock levels
- orders: order counts, revenue
- marketplace: import jobs, staging products
- Update dashboard routes to use StatsAggregator instead of direct imports
- Fix VendorPlatform junction table usage (Vendor.platform_id doesn't exist)
- Add comprehensive documentation for the pattern
This architecture ensures:
- Dashboards always work (aggregator in core)
- Each module owns its metrics (no cross-module coupling)
- Optional modules are truly optional (can be removed without breaking app)
- Multi-platform vendors are properly supported via VendorPlatform table

The require_module_access dependency was using path-based detection to
determine admin vs vendor authentication, which failed for API routes
(/api/v1/admin/*) because it only checked for /admin/*.
Changes:
- Make frontend_type parameter mandatory (was optional with fallback)
- Remove path-based detection logic from require_module_access
- Update all 33 module route files to pass explicit FrontendType:
- 15 admin routes use FrontendType.ADMIN
- 18 vendor routes use FrontendType.VENDOR
This ensures authentication method is explicitly declared at route
definition time, making it independent of URL structure and future-proof
for API version changes.

The get_admin_context function signature changed to require db as
the second argument, but many admin route handlers were still using
the old signature (request, current_user).
Updated all occurrences across modules:
- core, catalog, dev_tools, inventory, customers, messaging
- billing, tenancy, monitoring, analytics, orders, marketplace
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Introduces a module-driven context provider system that allows modules to
dynamically contribute template context variables without hardcoding imports.
Key changes:
- Add context_providers field to ModuleDefinition in app/modules/base.py
- Create unified get_context_for_frontend() that queries enabled modules only
- Add context providers to CMS module (PLATFORM, STOREFRONT)
- Add context providers to billing module (PLATFORM)
- Fix SQLAlchemy cross-module relationship resolution (Order, AdminMenuConfig,
MarketplaceImportJob) by ensuring models are imported before referencing
- Document the entire system in docs/architecture/module-system.md
Benefits:
- Zero coupling: adding/removing modules requires no route handler changes
- Lazy loading: module code only imported when that module is enabled
- Per-platform customization: each platform loads only what it needs
- Graceful degradation: one failing module doesn't break entire page
