## Summary When the platform database is briefly unreachable while a run is resuming from a wait, the run no longer fails with `TASK_EXECUTION_ABORTED`. The worker now retries the resume through the outage instead of aborting on the first blip. ## Root cause Resuming a run calls the engine's `continue` worker-action endpoint. That route caught every error and returned a `422`, which the worker's HTTP client treats as non-retryable. So a transient Prisma infrastructure error (for example `P1001` "Can't reach database server") was flattened into a permanent failure: the worker gave up, force-killed the run process, and completed it with `TASK_EXECUTION_ABORTED`. ## Fix - The `continue` route now lets infrastructure errors propagate to the generic 500 handler (message scrubbed, and retryable by the worker's HTTP client), the same treatment the trigger path already gives them via `isInfrastructureError`. Genuine validation errors (snapshot mismatch, invalid state) still return `422`, so a stale retry stays non-retryable. Resuming is idempotent server-side (guarded by the snapshot id), so retrying is safe. - The worker's `continueRunExecution` calls (both the runner-to-supervisor and supervisor-to-engine hops) retry with a longer, jittered backoff so they can ride out an outage lasting tens of seconds, and the jitter keeps a fleet of resuming runs from stampeding the database the moment it recovers. Builds on #3960, which scrubbed the leaked message on these routes but left the status non-retryable. No changeset: this is a server-side behaviour fix recorded via `.server-changes`. The `@trigger.dev/core` edits are internal run-engine worker plumbing, not a public API change.
Server Changes
This directory tracks changes to server-only components (webapp, supervisor, coordinator, etc.) that are not captured by changesets. Changesets only track published npm packages — server changes would otherwise go undocumented.
When to add a file
Server-only PRs: If your PR only changes apps/webapp/, apps/supervisor/, apps/coordinator/, or other server components (and does NOT change anything in packages/), add a .server-changes/ file.
Mixed PRs (both packages and server): Just add a changeset as usual. No .server-changes/ file needed — the changeset covers it.
Package-only PRs: Just add a changeset as usual.
File format
Create a markdown file with a descriptive name:

Description
The body text (below the frontmatter) is a one-line description of the change. Keep it concise — it will appear in release notes.
Writing guidance
These entries are public-facing - they ship verbatim in user-visible release notes. A few rules to keep them clean:
- One sentence is usually enough. The body is the bullet in the changelog. If you need a paragraph, you're probably describing the implementation rather than the change.
- Describe behavior, not implementation. Skip internal scopes, middleware names, library specifics, framework internals. Users care about what's different for them, not how it's wired.
- Never name internal tools or infra. Observability stacks, internal services, infra components, monitoring backends, CI surfaces, AWS specifics - none of these belong in user-facing notes.
Lifecycle
- Engineer adds a
.server-changes/file in their PR - Files accumulate on
mainas PRs merge - The changeset release PR includes these in its summary
- After the release merges, CI cleans up the consumed files
