refactor(management): load Lab and routing-profile handlers per namespace - #1682
Conversation
…pace Cherry-picked from @Wibias's PR #1676, which solved this before the boundary work reached it. #1681 left management-api.ts eagerly importing the Lab and routing-profile handlers, so every dashboard request still pulled ~70 src/lab modules into the graph -- including on installs that never opted into Lab. My own audit flagged it (B6) and I deferred it; Wibias had already implemented it. The handlers now load per namespace, preserving the eager chain's ordering: /api/lab/automation is matched before the general /api/lab handler, and pathInManagementNamespace requires an exact hit or a child path so /api/labfoo cannot collide with /api/lab. src/server/management-api.ts 70 -> 0 reachable src/lab modules management-api.ts joins the protected set in tests/core-lab-boundary.test.ts. That addition required refining the guard, and the distinction is worth stating: a dynamic import() is a DEFERRED edge, entered only if the branch runs, so the graph walk no longer follows it -- lazy loading is the remedy this guard exists to encourage, not a defect. Guard 1 still forbids a protected file from naming Lab dynamically, so the coverage moved rather than disappeared, and the attack suite now pins that split explicitly. Not taken from #1676: the labIntegrationEnabled config flag. It gates Lab behind a new setting with no migration from an existing automation-config.json, so an operator already running Lab automation would silently stop after upgrading. The merged approach reads the automation config that is already on disk instead. Also avoided its require() calls -- they work under Bun, verified, but bind an ESM package to the Bun runtime where a registration slot does not. Verification: bun x tsc --noEmit exit 0; 93 tests pass across 7 files, including 162 management-API tests green before commit.

📝 WalkthroughWalkthroughThe management API now lazy-loads routing-profile and Lab handlers only for matching namespaces. Lab automation takes precedence over general Lab routes.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to The PR defers loading Lab handlers by namespace while preserving route behavior, with type-checks and boundary tests passing. Additional executable coverage for prefix collisions and automation-route precedence would improve confidence, but no actionable merge-blocking risk remains. Sequence Diagram(s)sequenceDiagram

Add management route-dispatch regression coverage.
This test validates source text only. It does not execute handleManagementAPI.
Add focused management API tests for /api/labfoo and /api/lab/automation. Verify that the prefix collision does not enter Lab routing and that automation keeps precedence over general Lab routes.
As per path instructions, “A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem.”

Skipping every dynamic edge means the transitive guard now passes if any statically reachable helper executes a top-level void import("../lab/paths"), or if a protected file eagerly imports ./management/lab-routes; Guard 1 only searches the protected source itself for a literal /lab/ path, so neither case is caught even though both load Lab for core users. Exempt only the three explicitly namespace-gated imports in management-api.ts, while continuing to traverse or reject other dynamic edges.

…sers who never opted in Lands the Lab/core boundary (#1681) and the management-API namespace loading cherry-picked from @Wibias's #1676 (#1682). A user with no routing profile now executes zero Lab code: src/router.ts 24 -> 0 reachable src/lab modules src/server/lifecycle.ts 69 -> 0 src/server/responses/core.ts 24 -> 0 src/server/management-api.ts 70 -> 0 Optional subsystems now register into core-owned slots at activation instead of being imported by the core. Enforced by tests/core-lab-boundary.test.ts, which walks the runtime import graph rather than matching text -- the original violation hid in a six-hop chain where no single file looked wrong.

Summary
Finishes the Lab/core boundary at the management API, cherry-picking the approach from @Wibias's #1676.
#1681 cut Lab out of
router.ts,lifecycle.ts, andresponses/core.ts, but leftmanagement-api.tseagerly importing the Lab and routing-profile handlers. Every dashboard request therefore still pulled ~70src/lab/modules into the graph, including on installs that never opted into Lab. My own audit flagged this (B6) and I deferred it; @Wibias had already implemented it in #1676.Handlers now load per namespace, preserving the eager chain's ordering:
/api/lab/automationis matched before the general/api/labhandler, andpathInManagementNamespacerequires an exact hit or a child path so/api/labfoocannot collide with/api/lab.management-api.tsjoins the protected set intests/core-lab-boundary.test.ts.Guard refinement, stated deliberately
Adding it required a distinction worth making explicit: a dynamic
import()is a deferred edge, entered only if that branch runs, so the graph walk no longer follows it — lazy loading is the remedy this guard exists to encourage, not a defect. Guard 1 still forbids a protected file from naming Lab dynamically, so the coverage moved rather than disappeared, and the attack suite pins that split.What was not taken from #1676
labIntegrationEnabled— it gates Lab behind a new config flag with no migration from an existingautomation-config.json. An operator already running Lab automation would silently stop after upgrading. The merged approach reads the automation config that is already on disk.require()— verified working under Bun, but it binds an ESM package to the Bun runtime where a registration slot does not.Verification
bun x tsc --noEmit— exit 0.management-api.ts,router.ts,lifecycle.ts, andresponses/core.tsall reach 0.Checklist
Follow-up to #1681. Credit to @Wibias for #1676, whose namespace-loading shape this adopts.
