## Summary
- `internal-packages/rbac/src/index.ts` — in `LazyController.load()`'s
catch block, throw an Error when `process.env.REQUIRE_PLUGINS === "1"`
instead of silently falling back. The throw is captured into the lazy
controller's init promise, so it surfaces on the first method call.
- `apps/webapp/app/routes/healthcheck.tsx` — `await
rbac.isUsingPlugin()` after the DB ping. With `REQUIRE_PLUGINS=1` and a
failed plugin load, the throw surfaces here and the healthcheck returns
500 → readiness probe fails → rollout is rolled back. Noop for
self-hosters.
- `.server-changes/require-plugins-fail-fast.md` — server-changes entry.
- `internal-packages/rbac/src/require-plugins.test.ts` — 4 unit tests
covering loader branching: unset → fallback, `=1` → throw,
`forceFallback: true` wins, only exactly `"1"` enforces.
- `internal-packages/testcontainers/src/webapp.ts` — adds
`requirePlugins?: boolean` to `StartWebappOptions`. Implies
`forceRbacFallback: false`.
- `apps/webapp/test/healthcheck-require-plugins.e2e.test.ts` — e2e
closes the loop: spawns a real webapp, hits `/healthcheck` via HTTP,
asserts 500 with `REQUIRE_PLUGINS=1` and 200 without.
## Motivation
Today the RBAC plugin loader catches any plugin-load failure (missing
module, broken transitive dep, init throw) and silently returns the
default fallback implementation. This is the correct behaviour for
self-hosters who don't ship the plugin — but it's dangerous in
deployments where the plugin is expected to load: an
accidentally-missing or broken plugin would silently disable
enforcement.
`REQUIRE_PLUGINS=1` makes the loader fail loudly in those deployments.
The variable name is intentionally plural and generic — future plugin
contracts (audit logs, SSO) can read the same flag without renaming.

[TRI-9852](https://linear.app/triggerdotdev/issue/TRI-9852/require-plugins1-fail-fast-for-required-plugin-loads).
## Test plan
- [x] `pnpm run test --filter @trigger.dev/rbac` — 38/38 tests pass,
including the 4 new loader tests
- [x] `pnpm run typecheck --filter webapp` — passes
- [x] `pnpm run typecheck --filter @trigger.dev/rbac --filter
@internal/testcontainers` — passes
- [x] e2e test added (`healthcheck-require-plugins.e2e.test.ts`) — CI
runs it via `e2e-webapp.yml`. Couldn't run locally (no Docker daemon
up); CI has Docker provisioned.
