fix(webapp): show scheduled runs under their correct region

[ericallam]

Summary

Runs routed onto a dedicated scheduled worker queue were showing under a phantom region in the dashboard, run details, and the API, and slipped through region filters. They now resolve to their real region everywhere.

Fix

A worker queue can carry a :scheduled suffix that routes scheduled-lineage runs onto their own list. That suffix is an internal routing detail, but it was leaking anywhere the worker queue is read as a region. A baseWorkerQueue helper strips any :<class> suffix back to the base region (region names never contain a colon, so it's everything before the first colon) and is applied at every region read site: the runs list, run detail, the public API, and replay's region override. The runs-replication writer also stores the base region in ClickHouse so the region filter matches.

Learning: In the triggerdotdev/trigger.dev codebase, webhook URLs are not expected to contain embedded credentials/secrets (e.g., fields like `ProjectAlertWebhookProperties` should only hold credential-free webhook endpoints). During code review, if you see logging or inclusion of raw webhook URLs in error messages, do not automatically treat it as a credential-leak/secrets-in-logs issue by default—first verify the URL does not contain embedded credentials (for example, no username/password in the URL, no obvious secret/token query params or fragments). If the URL is credential-free per this project’s conventions, allow the logging.

Learning: When handling Prisma error P1001 ("Can't reach database server") in TypeScript, don’t assume a single error shape. Prisma can surface P1001 via two different error classes/fields: `PrismaClientKnownRequestError` exposes it as `err.code === "P1001"` (common during mid-query connection drops), while `PrismaClientInitializationError` exposes it as `err.errorCode === "P1001"` (common on client startup failure). Therefore, predicates should use `err.code === "P1001" || err.errorCode === "P1001"`. Do not flag `err.code === "P1001"` as “unreachable/never matches,” as it is expected in production.

Learning: When handling Prisma errors for P1001 ("Can't reach database server"), do not assume it only appears under a single property name. Prisma may surface P1001 via either `PrismaClientKnownRequestError` (`err.code === "P1001"`, e.g., mid-query connection drops) or `PrismaClientInitializationError` (`err.errorCode === "P1001"`, e.g., client startup connection failure). To reliably detect the condition, check `err.code === "P1001" || err.errorCode === "P1001"`, and avoid review rules that would incorrectly flag `err.code === "P1001"` as unreachable/never-matching.

Learning: In the triggerdotdev/trigger.dev webapp test suite, it is acceptable to leave `createInMemoryTracing()` calls that register a global `NodeTracerProvider` without `afterEach`/`afterAll` teardown. Do not flag this as a test-ordering risk when the code follows the established pattern used across webapp tests (e.g., replication service/benchmark/backfiller tests). This is considered safe because `trace.getActiveSpan()` when called outside a `context.with(...)` block reads `AsyncLocalStorage.getStore()` (undefined when no `run()` scope exists), so it falls back to `ROOT_CONTEXT` with no attached span—regardless of which provider is registered.

Learning: In this Remix + TypeScript codebase, do not flag a server/client boundary violation when a file imports only types from a module matching `*.server`.

Specifically, it’s safe to import types using `import type { Foo } from "*.server"` or `import { type Foo } from "*.server"` because TypeScript erases type-only imports at compile time and they emit no JavaScript, so they won’t cross the Remix server/client bundle boundary.

Only raise the boundary concern for value imports (e.g., `import { Foo }` without `type`, or `import Foo`), since those produce JavaScript output.

Learning: In the triggerdotdev/trigger.dev repo, the policy “Never mock anything — use testcontainers instead” should only be enforced for integration tests that interact with real external services (e.g., Redis, Postgres) via actual infrastructure. For unit tests that exercise pure in-memory logic (e.g., cache semantics) it is OK to stub collaborators such as `ApiClient` using Vitest (`vi.fn()`) to assert call counts or control behavior. Do not flag `vi.fn()`-based `ApiClient` stubs in unit tests as violations of the testcontainers policy.

Learning: When reviewing TypeScript in this repo, apply the rule “prefer type aliases over interfaces” only to data/object shapes and union/intersection type modeling. If an interface is being used as a behavioral contract for collaborators to implement (e.g., method-shape interfaces that define required behavior, such as `BackpressureLogger` / `BackpressureSignalSource` in `apps/supervisor/src/backpressure/backpressureMonitor.ts`), keep it as an `interface` and do not flag it as a type-alias-vs-interface violation.

Walkthrough

This PR introduces a baseWorkerQueue helper function that strips the :scheduled suffix from worker queue names, enabling scheduled-split queues to resolve back to their base region. The helper is then applied across six files: three presenters normalize API responses and span lookups, three services/routes normalize region handling for replays and data replication, and tests verify correct suffix stripping across multiple queue formats. A changelog entry documents the fix.
