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.
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.
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.
Both server ratchets only logged an entry the tree had moved past. A
file that shrank could grow back to its old size entry unseen, a
deleted file left its allowance to the next file at its path, and a
boundary violation that was fixed stayed allowed until someone ran
--update. The client ratchets now fail on such entries, so the server
ones do the same.
lint:size fails on an entry above its file's size or for a file that is
gone, and lint:boundaries on an entry that no longer occurs; both tell
to run --update, which still only lowers or drops. Both baselines match
the tree today.
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.
