## Summary
v3 (the engine that ran the SDK v3 era, internally
`RunEngineVersion.V1`) is end-of-life. Following the removal of the v3
execution apps
([#4194](https://github.com/triggerdotdev/trigger.dev/pull/4194)) and
the legacy dev websocket
([#4198](https://github.com/triggerdotdev/trigger.dev/pull/4198)), this
removes the remaining v3 execution stack from the server.
Clients still on v3 (an old SDK or CLI that has not upgraded) keep
getting a clear "upgrade to v4" response. Triggers, batch triggers,
reschedules, and deploys that resolve to v3 are rejected with a graceful
4xx pointing at the migration guide, never a 5xx, so a stale client
cannot affect server health. Self-hosted instances still running v3
should stay on the 4.5.x release line until they migrate.
## What is removed
- The MarQS queue and its shared/dev queue consumers.
- The v3 socket.io namespaces (coordinator, provider, shared-queue) and
the v3 run lifecycle services (attempt, checkpoint, and batch-resume).
- The graphile-worker background job system; all live jobs already run
on `@trigger.dev/redis-worker`.
- The `DEPRECATE_V3_ENABLED` flag: v3 is now rejected unconditionally,
so the flag is gone.
- Unused v3 exports from `@trigger.dev/core` (the `v3/zodNamespace`
subpath and the legacy socket message catalogs) and the now-dead MarQS
environment variables.
## What stays
The v4 engine is untouched. The graceful v3 rejection boundary stays,
`determineEngineVersion` still detects a v3 project so it can reject it,
and the batch service plus batch-completion worker stay for current
clients. Live queue concurrency limits and metrics now read from the v4
run engine instead of MarQS, and a brand-new dev environment now
defaults to v4.
## Dependency cleanup
Removes webapp dependencies left unused by this change: `seedrandom` and
`semver` (only the removed v3 code used them) plus a set that was
already dead, their orphaned `@types` packages, and two dead files. Adds
a `knip:deps` script and a `knip.json` config so unused dependencies can
be found the same way going forward.
## What & why
Two related fixes to how new cloud organizations get onboarded onto the
Free plan.
### 1. Route new cloud orgs through plan selection
New cloud organizations were created already activated, so they skipped
the plan-selection step and went straight to creating projects — which
meant their plan and usage limits were never set up. They're now created
deactivated and routed through plan selection, which activates them once
a plan is chosen. Self-hosted installs have no plan-selection step, so
they're activated immediately on creation and are unaffected.
The `Organization.v3Enabled` field is renamed to `isActivated` to better
describe what it now gates. It's mapped to the existing `v3Enabled`
column, so there's no data migration — only a schema/code rename.
### 2. Allow selecting the Free plan without GitHub verification
Choosing the Free plan no longer requires connecting and verifying a
GitHub account. The plan is applied immediately when selected. This
removes:
- the "Connect to GitHub" dialog and the GitHub-verified badge from the
plan picker
- the account-rejected state
- the now-unreachable GitHub-connect return routes
## Notes
- These changes pair with the corresponding change in the billing
service that applies the Free plan directly; they should be released
together.
## Testing
Verified locally end to end: a new cloud org is routed to plan
selection, the Free plan applies in one click with no GitHub step, the
org is activated, its usage allowance is provisioned, and it lands on
the new-project page.
🤖 Generated with [Claude Code](https://claude.com/claude-code)
Once this is merged, oxlint is at a pretty sensible baseline.
**Enable `no-unused-vars`, `typescript/consistent-type-imports`, and
`import/no-duplicates` lint rules**
Turns on three previously-disabled oxlint rules across the monorepo and
fixes all violations:
- **`no-unused-vars`** – enabled as an error with standard ignore
patterns: unused function arguments are ignored by default (`args:
"none"`), variables/caught errors/destructured array elements prefixed
with `_` are allowed, and rest siblings are permitted.
- **`typescript/consistent-type-imports`** – enforced as an error; all
type-only imports now use the `import type` syntax.
- **`import/no-duplicates`** – enforced as an error; duplicate import
statements from the same module have been merged.
The remaining commits clean up the violations found across the codebase:
removing unused variables/imports/type aliases, adding `_` prefixes to
intentionally unused bindings, fixing duplicate imports, and converting
value imports to `import type` where appropriate.
