src/nest-rpc, src/nest-mcp and src/mcp import domains and are imported by them, but the domain map only knew src/nest, so their edges dropped out of domainCycles and their repository injections out of foreignRepositories. Each layer now counts as one domain. The repository rule reads the syntax tree for @InjectRepository(X) and for getRepository(X) on an EntityManager, so a comment no longer counts and a foreign read through the EntityManager no longer passes. The baseline takes the cycles and the repository reaches the wider view finds; settings -> Users goes, it was a comment.
VacayMcp read the caller's username and email straight from UsersRepository, a table the auth domain owns. UserLookupService in auth-core answers exactly that, so vacay neither imports AuthModule nor injects a foreign repository, and its foreignRepositories entry goes.
The module comment no longer spells an @InjectRepository call the scanner took
for a foreign Users injection in nest/database, and journey's Users entry is
gone now that it reads the Immich flag through UserImmichRepository.
A domain injecting the repository of a table another domain owns couples
the two below the service layer, and nothing counted it. The new
foreignRepositories rule reads every @InjectRepository under src/nest,
looks the entity up in scripts/repository-owners.json (an injected entity
without an owner stops the run) and holds each domain/entity pair to the
baseline, which only shrinks: 209 pairs today.
VacayMcp injected AuthService only to call getCurrentUser for the caller's
username and email before sending an invite or sharing the calendar, which
kept VacayModule importing AuthModule. UsersRepository.findUsernameEmail
answers the same two fields (and undefined for an unknown id, which the
tools already refuse as 'User not found.').
AddonsService read the transit backend through transit/transit-provider.ts
and built photo-provider endpoint paths with memories.helpers, so the addons
domain, which nearly every domain imports for its gates, depended on
transit and memories. Both are free functions over a repository or plain
strings; they move unchanged to common/, where the transit and admin sides
read them too.
The websocket gateway injected JourneyDomainService to decide who may join
a journey's book room, so the realtime domain, which nearly every domain
imports for its broadcasts, depended on journey and closed a cycle through
all of them. It now injects a JOURNEY_ACCESS port declared in realtime;
JourneyAccessModule (global, imported by AppModule beside the gateway
module) binds it to the same JourneyDomainService method.
The gateway imported hostVersion from the plugin install code to put the
version in its welcome frame, which made the realtime domain, imported by
nearly every other, depend on plugins. The running version (image VERSION
or APP_VERSION, else package.json) is app config; runningVersion() holds it
and the plugin host-compat checks call the same function.
NotificationsController, SettingsController, OidcController and the packing
template controller each imported their body DTO from admin/admin.dto.ts,
and AdminController imported the same four without using them. Those
imports tied the notifications, settings, packing and oidc domains to the
admin domain and through it to everything admin depends on. The classes
move unchanged (same names, same @trek/shared schemas) into each domain's
own dto file.
Every domain's *.rpc.ts was written against rpc-kit, rpc-params, rpc-errors
and PluginGuards, and every domain module imported PluginGuardsModule, all
of it inside src/nest/plugins, while PluginsRuntimeModule imports those same
domains so their handlers exist at boot. That made the plugins domain part
of every cycle. The kit imports no domain but the protocol tables and
permissions/addons for the guards, so it moves to src/nest-rpc beside
src/nest-mcp, with its tests, its README and its extraction rule; the
runtime module keeps its domain imports, which the boot-time coverage check
of the wire surface needs in any subset app.
JwtAuthGuard, OptionalJwtAuthGuard, CookieAuthGuard, AdminGuard, the global
and MFA guards, @CurrentUser, @Public, JWT verification and the ephemeral
token service lived in the auth domain, so every controller that checked a
session depended on the whole account module and its imports. They import
no domain themselves; under src/nest/auth-core they are shared kernel like
common/, every importer points there directly, and AtlasModule and
NotificationsModule stop importing AuthModule, which they only did for the
demo gate. lint:boundaries counts auth-core as kernel: 57 fewer cyclic
domain edges, the largest cycle shrinks from 46 to 40 domains.
Module boundaries were held by review alone. storage.module.ts documents
a cycle that only surfaced at runtime as "imports[1] is undefined", three
modules exist just to break cycles, and nothing stopped the next feature
from reaching into another domain's helpers.
scripts/import-boundaries.mjs parses every import under src/ with the
TypeScript parser and checks five rules against a baseline of today's
violations: load-time file cycles (none today once type-only and lazy
imports and the two-way MikroORM entity relations are left out), new
dependencies between domains that already depend on each other (262
pairs, one tangle around plugins and auth), shared-kernel files importing
a domain (8), imports of another domain's internals (69) and src/db
importing src/nest (5). A domain's public surface is what the code
already treats that way: modules, services, guards, decorators, types,
constants, the audit logger, the plugin RPC kit and the addon gates.
New violations fail, --update only drops entries, and an unreadable
baseline, a missing src/ or an import it cannot resolve stops the run.
