test(connection): make reconnect hardening deterministic

MacroscopeApp / Macroscope - Effect Service Conventions failed Aug 10, 2026 in 1m 51s

Effect Service Conventions: 1 issue found

  • apps/server/src/httpServerOptions.ts: the WebSocket options were moved out of server.ts but the accompanying comment was shortened, dropping the upstream uWebSockets bug reference (close 1006 on valid DEFLATE input) that documented why decompress: "shared" is required. That link no longer exists anywhere in the repo. Restore the original comment when relocating the constant.

No other convention violations found: the changed Effect code uses subpath namespace imports for effect/*, adds no new service definitions, layers, or error types, and the new wakeup reason is handled inside the existing supervisor state machine without introducing service-instance injection, ManagedRuntime.make, or runPromise in domain code.

Files reviewed in scope:

  • apps/mobile/src/connection/background-activity.ts — new connected-generation stream inside the existing Layer.effectDiscard; dependencies acquired via yield* EnvironmentRegistry / MobileStorage.MobileStorage; the EnvironmentSupervisor tag is accessed through Effect.map(EnvironmentSupervisor, ...) inside registry.followStream, matching the pre-existing named export from the connection barrel.
  • apps/mobile/src/connection/platform.ts — the added expo-network listener lives in a platform/native-callback adapter layer (Wakeups.layer), consistent with the existing connectivityLayer in the same file; no hidden runtime or fake dependency injection introduced.
  • apps/server/src/httpServerOptions.ts / apps/server/src/server.ts — plain configuration constant, not a service module, so make/layer conventions do not apply; only the comment-preservation issue above.
  • packages/client-runtime/src/connection/supervisor.ts and wakeups.ts — the new "network-path-changed" variant is a union member of ConnectionWakeup handled inline in the state machine; no new error classes, discriminators, or catchIf/catchTag usage added.
  • packages/client-runtime/src/rpc/session.ts — onPingTimeout logs a static message with bounded, safe annotations (environmentId, connectionLabel); no raw payloads or credentials.
  • packages/client-runtime/src/connection/supervisor.test.ts and apps/server/src/httpServerOptions.test.ts — behavior changes are covered by focused tests using the existing harness seams (probe/prepare callbacks), not mocks of core logic.

💭 Looking at the changed files to see what conventions they Now I'm reviewing the supervisor.ts changes to ensure they follow conventions around imports, service definitions, and error handling. The httpServerOptions.ts module looks fine as a plain config export. I need to check the new isApplicationActiveWakeup type in wakeups.ts and verify it aligns with the conventions. Looking at the conventions and patterns here—the I'm checking the control flow in waitForRetrySignal — the break statement inside the switch correctly exits just the switch block, letting the loop continue, which is the intended behavior. Now I'm reviewing the Effect service conventions, starting with the imports in the mobile connection file. The barrel's export of EnvironmentSupervisor is pre-existing design that the PR didn't modify, so that's not worth flagging. Looking at the new httpServerOptions.ts file—it's just a plain const module, not a service, which is fine. The comments were preserved from the original server.ts file, though the thought cuts off mid-comment about something related to uW. The upstream issue link and close-1006 detail were legitimate spec documentation that shouldn't have been dropped—that's a change-discipline violation worth flagging. The new test for httpServerOptions is just a tautological snapshot of the constant rather than a behavior test, so I'm inclined not to flag it as a style issue. Now I'm considering whether extracting bunWebSocketOptions into a separate file is a good candidate for flagging as a change. Looking at other changes: session.ts adds logging annotations with environmentId and connectionLabel, which is safe and bounded. The mobile platform layer is more interesting—it uses React Native's Network API inside Effect.sync within a Stream callback, which technically violates the guideline about hiding imperative dependencies in Layer implementations. But this is a platform adapter at the application boundary, and the same pattern already exists elsewhere in the file with connectivityLayer, so it's consistent with the established approach. There's also a fire-and-forget promise inside Effect.sync, which is imperative but acceptable here since it's wrapping native RN listener callbacks. The real question is whether there's a race condition with networkType ??= current.type ?? null;—the listener could set networkType before the promise resolves, then the nullish coalescing would skip the update. Actually, that's fine because ??= only assigns if the value is null or undefined, so if the listener already set it, the async seed won't overwrite. The only meaningful issue I'm finding is that a useful comment with the uWebSockets bug link and explanation of the 1006 code got dropped during the move. That's a convention violation since the guidance explicitly says to preserve specification documentation, so I should flag it as a suggestion to restore the full comment on httpServerOptions.ts. The check defaults to failure when findings exist, so I'll report this as a failure state. Let me verify there aren't other more substantive issues by checking the test harness and the waitForSignal refactor. Looking at the supervisor.ts timeout logic, the reason handling changed from checking for "application-active-probe" to just "application-active", which is functionally equivalent across I notice the upstream documentation link was removed during the refactoring, which is a loss of useful context. I should add an inline comment to httpServerOptions.ts that restores the key details about how permessage-deflate negotiation works with clients, explaining that connected clients without compression support still receive uncompressed frames while a dedicated compressor manages per-connection state.

1. modify_pr — One change-discipline finding: documentation lost while moving the WebSocket options out of server.ts. Everything else in the changed Effect service code (supervisor wakeup handling, wakeups.ts union, mobile platform layer, rpc/session.ts hooks) follows the conventions.
