A dynamic `import()` +inside it is impossible without making the chain async, which would touch ~11 production +call expressions, ~272 test call sites, and — the actual blocker — the synchronous +subagent-fallback API in `src/codex/subagent-model-fallback.ts` (`tryRouteFallbackModel:63` +feeding `isNativeModelQuotaExhausted:200`, `isModelHealthBlocked:216`, +`isSubagentModelUnavailable:234`, `selectAvailableSubagentModel:269`, +`noteSubagentModelFailure:298`, `applySubagentModelFallback:510`). + +Making routing async to remove a Lab import would be a far larger and riskier change than +the problem justifies. **Routing stays synchronous.** The boundary is drawn with a +provider-registration seam instead. + +## Design: registration, not dynamic import + +The core already owns the exact pattern needed — `src/lib/server-resource-ownership.ts`, +`registerCurrentServerResourceCleanup` — and Lab already consumes it at +`lab/automation/orchestrator.ts:104`.

These five functions +are synchronous, so no `await` fits. + +The failure is silent: during the window a policy alias is dropped from the fallback chain +and the subagent runs on **a different model than the operator configured** — no error, no +log, just a `skipped` entry. That is worse than the 404 it replaced, because a 404 is +visible. + +I checked the swallow myself: `routeModel` is called inside `try { } catch { return null }` +at `subagent-model-fallback.ts:63-68`. The reviewer is right. + +## R2-2 (High) — the 5s timeout fails identically, 5 seconds later + +`060:53-54` claimed that on timeout "the existing unknown path applies". It does not. +Timeout lands on exactly the fail-closed chain the gate existed to avoid: +`policy.ts:95` → `profile.ts:41` (`exclude`) → `evaluator.ts:352` → `router.ts:528` throw +→ 404 at `responses/core.ts:1618`. + +The reviewer also rejected the obvious shortcut, correctly: forcing unknown→`allow` while +pending would silently override the operator's fail-closed intent on every +default-configured compatibility profile, converting a routing-availability bug into a +**policy-bypass bug**. A compatibility gate exists precisely to not do that. + +## R2-3 (High) — deactivation has no safe teardown, and the abort primitive is global + +Detaching dispatch deps deletes the map entry (`orchestrator.ts:99`), after which +`dispatchDepsFor` returns `{}` (`:66`). A run already inside `runDispatchBatch` re-reads +deps at `:360` and dispatch hits `if (!deps.routeExecutor) return routeIneligible();` +(`dispatch.ts:134`) — finalizing the run as **ineligible rather than cancelled**, writing a +misleading terminal state into the ledger. + +The alternative is worse: `requestLabAutomationShutdown` (`orchestrator.ts:114`) sets +`shutdownRequested`, a module-global (`:56`) gating dispatch for *every* `configDir` +(`:314`), cleared only by `startLabAutomationScheduler` (`:402`). Deactivating one config +would wedge automation for all others — the exact multi-config bug B3 set out to fix. + +## R2-4 (High) — the reconcile predicate drops automation-only installs + +`labActivationRequired` is a disjunction: profiles present **or** automation enabled. +`060` described reconcile as driven by profile mutations, so deleting the last profile +would tear down a scheduler the operator explicitly enabled. + +--- + +# Amendment: activate before listen, deactivate never + +## A1 — activation completes before the listener accepts traffic + +This closes R2-1 and R2-2 together, because both are window defects. + +`src/cli/index.ts:236` already creates a `readinessGate` and passes it into +`startServer` (`:241`), and `src/server/readiness.ts:44` already owns the pending/ready +/failed lifecycle.

That still makes `server/index.ts` import `lib/lab-activation.ts`, which statically +imports Lab, which re-couples the graph. The resolution: + +- `server/index.ts` keeps a **dynamic** `import("../lib/lab-activation")`. +- The listener does not accept traffic until it resolves, using the existing readiness + gate: activation failure marks the gate failed; success marks it ready. +- Because `startServer` stays synchronous, the await lives in `cli/index.ts` around the + existing gate transition, where `handleStart` is already async and already awaits + `runStartupReadinessSync`. + +Net effect: for an install with routing profiles, Lab is fully registered before the first +request can be routed — synchronous or asynchronous, request path or subagent fallback. +For an install without them, nothing is imported at all. **There is no window.** + +The `awaitOptionalRoutingReadiness()` slot, the 5s timeout, and the `policy/`-only await +from `060` are all **withdrawn**.

A static import in the composition root loads the + graph but creates no directory, opens no SQLite handle, and starts no timer. + +So the owner's guarantee holds exactly as stated: **a profile-less user executes no Lab +code.** What remains is the evaluation cost of ~69 modules for profile-less users, stated +plainly in `080` rather than hidden. + +## R3-1 (Medium) — dry-run evaluates policies outside the activation gate + +This is the concrete "guard passes while Lab executes" path. + +`POST /api/routing-profiles/dry-run` calls `assembleCandidateEvidence` +(`routing-profile-routes.ts:362` → `:103`), with a static import of the assembler at +`:19`, entirely independent of `labActivationRequired`. + +After phase 3 the assembler consults the provider slot. On an install started without +profiles the slot is null, so dry-run returns candidates with **no compatibility +evidence** — the operator's preview disagrees with what production does once Lab +activates. And the `080` behavioral assertion ("slots null, no scheduler timer") stays +true throughout, so the guard passes while the property it stands for is violated. + +Narrow but reachable: dry-run requires a resolvable profile (`:350`), so it needs a +profile created at runtime on a process started profile-less — exactly the Q3 case. + +**Amendment.** Two calls, both synchronous: + +1.

The dry-run branch calls `activateLab` before assembling evidence when + `labActivationRequired(config, configDir)` is true. + +Phase 4's behavioral assertion is extended: on a genuinely profile-less config, a dry-run +request must register no slot.
