test(lab): check that the sync activation window's callees are synchronous - #4674
Conversation
…onous The existing guard scans the text between `Bun.serve` and `return server` for a body-level await. That window is 178 lines and calls ten free functions plus eleven receiver methods. If one of those callees becomes `async`, startServer no longer waits for it, the ordering the window exists to protect is gone, and the window text still has no `await` in it, so all four existing checks stay green. `activateLab` is the function that ordering is about. Making it async is a one-word change that the guard could not see. Two checks close that. "functions the window calls are synchronous" collects the body-level call sites in the window, splits them into free functions and receiver methods, resolves each free function through src/server/index.ts's imports and one level of re-export to the module that declares it, and asserts the declaration is not `async` and its body has no body-level await. Names it cannot resolve go in UNRESOLVED_CALLEES with a reason rather than being skipped, because a silent skip is how this kind of check rots. Receiver methods go in SYNC_WINDOW_RECEIVER_CALLS, and the collected set must match that list exactly, so a new `obj.method()` in the window fails the test and forces a review. Depth is one on purpose. Walking every function those callees invoke produces false positives on dynamic dispatch, and the regression this exists to catch lands at depth one. "the callee scan is not vacuous" pins the scanner against synthetic input and fails if the collector finds no free function at all, which is how a collapsed window would otherwise measure an empty string and pass. Driven red to prove it is not vacuous: declaring src/lib/lab-activation.ts's `activateLab` `async` leaves all four existing checks green and fails only the new one, with "activateLab in src/lib/lab-activation.ts: declared async". The declaration was restored; the suite is 19 pass / 0 fail.

This only rejects an async declaration or a body-level await, so it still passes if activateLab remains synchronous syntactically but defers registration—for example, function activateLab(...) { void activateLabAsync(...); } or return import(...).then(registerSlots). In that scenario startServer returns before the evidence provider is installed, violating the ordering this guard is intended to enforce. Assert the activation side effect is visible immediately after the call, or trace promise/deferred work rather than treating the absence of async/await as proof of synchronous completion.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not skip => in type positions. collectBodyLevelCalls would skip makeReconcilerStop() in const stopReconciler: () => void = makeReconcilerStop();: skipConciseArrowBody scans from void to the statement terminator and bypasses the initializer. The named binding is not currently present, but this remains a material false-negative for the guard's body-level callee scan. Detect value-position arrows before skipping, and add a regression case that expects makeCb in free; documenting the omission would preserve the gap.

* fix(server): break the startup-warnings import cycle and repoint the chat-wire oracle
Two defects the first push of this split carried, both found by verification
rather than by reading the diff.
startup-warnings.ts imported `startServer` back from the facade. Nothing in that
leaf uses it: the only occurrence is the word `startServer` inside a JSDoc
paragraph. The codemod that generated the leaf headers treated a comment mention
as a use, so it emitted the import, and that made the facade and the leaf a
value-level cycle. Importing the leaf then pulled a partially initialised server
graph, which is why suites with no connection to src/server/index.ts went red.
The import is removed; the comment is untouched.
tests/server/loopback-listener-admission.test.ts has a third oracle in it, "the
chat wire finishes CORS with the receiving listener's policy", that reads the
describe-level source and searches for the /v1/chat/completions and /v1/live
route branches. Both moved into the serve-options leaf, so indexOf returned -1,
the slice was empty, and the CORS assertions would have passed while checking
nothing. The describe-level read now concatenates the facade and the leaf, which
is what the allowlist tests in the same block and this one respectively need.
* fix(server): route the startup cache-invalidation flag through a setter
CI typecheck caught what the worktree's partial check could not: the facade still
assigned `startupCacheInvalidationWrote` at two points, but that flag moved into
the startup-warnings leaf with its reader. An ES import binding is read-only, so
the assignment no longer compiles across the module boundary.
The flag stays next to `consumeStartupCacheInvalidationWrite`, which is the only
thing that reads and clears it, and the composition root now calls
`setStartupCacheInvalidationWrite`. Keeping the flag and its reader in one module
is the point: splitting them would let a future edit reset one without the other.
The startup-warnings import collapsed to a single line, matching the re-export
lines already in this file, which keeps the facade at 893 lines. The ratchet only
lowers caps, so the cap is 893 rather than the 898 recorded a commit ago.
* docs(devlog): record the server/index.ts outcome and the three defects verification caught
* test(server): repoint the loopback-listener seam oracle at the serve-options leaf
tests/server/loopback-listener-integration.test.ts has a describe that reads
src/server/index.ts as text for three properties with no runtime oracle on this
Bun version. Two of them -- the explicit 127.0.0.1 binds for the loopback
listener and the hub management ingress -- stayed in the composition root next to
Bun.serve. The third, that the WebSocket upgrade uses the receiving server rather
than the captured binding, moved with the fetch handler, so
`requestServer.upgrade(req,` dropped to zero matches and `.toBe(3)` failed.
The read now concatenates the facade and the serve-options leaf, which satisfies
all three: 3 upgrade call sites, no `server.upgrade(req,`, and both binds.
This is the third oracle this round that a literal path search did not find. It
builds its path from `join(process.cwd(), "src", "server", "index.ts")`, so the
candidate set my detector generated never reached src/server/index.ts. The three
misses had three different shapes, which is the argument for not relying on a
static detector: `bun run test:changed` found this one in 40 seconds against
2,249 tests, where the earlier two each cost a full CI round.
* test(update): repoint the /healthz identity oracle at the serve-options leaf
tests/update/update-stop-first.test.ts reads src/server/index.ts as text and
pins three fields of the /healthz payload: `service: "opencodex"`,
`pid: process.pid` and `port: healthPort`. All three live in the route handler,
which moved into the serve-options leaf, so the facade read found none of them.
The read now concatenates both; this is the only place in that file that reads
server source.
This is the fourth oracle this round that neither a literal path search nor
`bun run test:changed` found. It builds its path from
`join(repoRoot, "src", "server", "index.ts")`, and because it reads the file as
data rather than importing it, the changed-import graph never selects it --
exactly the indirect-dependency case AGENTS.md calls out as the reason the full
suite is sometimes required. CI's `test 3/4` shard named it directly.
The remaining candidates were enumerated and run: the eleven other tests that
mention src/server/index.ts do so in comments, through the import graph, or read
content that stayed in the facade. 235 pass, 0 fail.

functions the window calls are synchronouscollects body-level call sites in the window and splits them into free functions and receiver methods. Each free function is resolved throughsrc/server/index.ts's imports and one level of re-export to the module that declares it, then asserted to be neither declaredasyncnor to contain a body-level await. The ten it resolves arebindNativeMainStartupLifecycle,setServerRef,setCorsOrigin,isCanonicalOpenAiForwardProvider,providerCodexAccountMode,getConfigDir,labActivationRequired,activateLab,activateResetCreditAutoRedeemandcreateResetCreditWhamClient; three of those resolve through a re-export barrel.Names it cannot resolve go into
