## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - A managed instance gets its instance-level environments from the
`PAPERCLIP_MANAGED_CONFIG` document, and #19508 added plugin environment
entries to it
> - Greptile's Apex review of #19508 arrived after it merged, with three
findings
> - A credential inside an array nested in an array passed the secret
check and the response redaction
> - Recovery of an archived environment listened on one worker handle,
which a restart replaces, and its attempts were not tracked through idle
checks and shutdown
> - This pull request closes all three findings
> - The benefit is that credentials never pass the check, an environment
comes back after any worker restart, and shutdown never cuts off a
recovery write
## Linked Issues or Issue Description
Refs #19508 (the Apex findings this pull request fixes)
**Subsystem affected**
Server environments: the managed-config parser, the environment routes'
response floor, the managed environment bootstrap, and the plugin worker
manager.
**Problem or motivation**
Greptile's Apex review of #19508 found three problems. (1)
`findSecretLikeConfigKey` and `redactSecretLikeConfigKeys` skip array
elements that are arrays, so `{"groups":[[{"apiToken":"..."}]]}` passes
the boot check and is echoed to restricted readers. (2) Recovery
subscribes to `ready` on one worker handle. A restart such as a settings
save replaces that handle, so the new worker's `ready` never reaches the
listener, and the environment stays archived. (3) A recovery attempt is
fire-and-forget. The worker manager's work token ends when the worker
replies, but the database write continues, so an idle check or the
database shutdown can overlap it.
**Proposed solution**
Walk arrays at any depth in both functions. Add a manager-wide
`onWorkerReady` subscription and use it for recovery. Run every recovery
attempt through a controller that tracks it as idle work and that
shutdown stops and awaits before the database closes.
**Alternatives considered**
Re-subscribing on each new handle after a restart. That needs a hook in
every restart path. The manager-wide subscription covers all of them in
one place.
**Roadmap alignment**
This only fixes code that #19508 added or touched. It adds no product
surface.
## What Changed
- `server/src/services/managed-config.ts`: `findSecretLikeConfigKey`
walks arrays at any depth (new `findSecretLikeConfigKeyInValue`). This
covers sandbox `config` and plugin `driverConfig`.
- `server/src/routes/environments.ts`: `redactSecretLikeConfigKeys`
walks arrays at any depth (new `redactSecretLikeConfigValue`).
- `server/src/services/plugin-worker-manager.ts`: new optional
`onWorkerReady(listener)` on `PluginWorkerManager`. It fires on every
worker `ready`, including a replacement handle from a restart. A
listener error is logged and does not affect the worker.
- `server/src/services/managed-environments.ts`:
- Sandbox and plugin recovery subscribe through `subscribeWorkerReady`.
It prefers `onWorkerReady` and falls back to the handle when the manager
has no such method.
- New `createManagedEnvironmentRecovery()` controller. Each attempt runs
inside `trackIdleWork` for its whole duration. `stop()` removes every
`ready` subscription, refuses new attempts, and awaits unfinished ones.
- `server/src/index.ts`: creates the controller, passes it to
`applyManagedEnvironments`, and awaits `stop()` during shutdown, after
the delivery workers stop and before the application teardown and
database close.
## Verification
- `cd server && npx vitest run src/__tests__/managed-config.test.ts`: a
secret-like key in an array nested in an array refuses boot, for plugin
`driverConfig` and sandbox `config`.
- `npx vitest run src/__tests__/environment-routes.test.ts`: a
nested-array credential is removed from the response, and other nested
values stay.
- `npx vitest run
src/services/managed-environments-plugin-entries.test.ts`:
- With `onWorkerReady`, recovery never consults the handle. It ignores
another plugin's `ready`, re-ensures on this plugin's `ready`, and then
unsubscribes.
- An attempt counts in `idleWorkSnapshot()` until its ensure settles.
`stop()` unsubscribes, waits for the unfinished attempt, and later
`ready` events start nothing.
- `npx vitest run src/services/managed-environments.test.ts
src/__tests__/managed-plugin-environments.test.ts`: pass.
- `pnpm --filter @paperclipai/server typecheck` passes.
- I did not run the full `pnpm test:run`, `pnpm -r typecheck` or `pnpm
build`. CI covers them.
## Risks
- The redaction now also walks nested arrays in sandbox config
responses. Only credential-shaped keys are removed; other values are
unchanged.
- The boot check now refuses a document that hides a secret-like key in
a nested array. A valid document has no such key.
- `onWorkerReady` is optional, so other `PluginWorkerManager`
implementations and test fakes keep working.
- Shutdown now waits for an unfinished recovery attempt. An attempt is
one worker call plus one short transaction.

Server tests that need a real PostgreSQL process must use
./helpers/embedded-postgres.ts instead of constructing embedded-postgres
directly.
The shared helper creates a throwaway data directory and a reserved-safe
loopback port for each test database. This protects the live Paperclip
control-plane Postgres from server vitest runs; see PAP-2033 for the incident
that introduced this guard.
