Display of the platform-managed default environment across the UI. Subsystem affected UI (environment selectors, agent config form, environments page, agents page, run details) and the claude-local/codex-local adapter auth checks. Current behavior The agent form labels the inherited default environment as "Name (sandbox)". Environment selectors and the environments list render "Name · sandbox". The agents page describes the environment as "<provider> sandbox provider". The agent form's fallback label is "Managed sandbox". Adapter auth checks say "The sandbox has no ready authentication for this adapter." Proposed behavior Platform-managed environment rows (`metadata.managedByPaperclip`) render their name alone. The fallback label is "Paperclip Computer". The agents page describes managed environments as "Managed by Paperclip". Run details omit the driver suffix for sandbox-driver environments (the adjacent Provider entry already identifies the mechanism). Adapter auth checks say "This environment has no ready authentication for this adapter." Reason and benefit The managed environment carries a product name. Appending the raw driver key ("sandbox") to it is noise and contradicts the product naming. User-created environments keep the driver suffix, so mixed lists stay distinguishable. Breaking changes None. Message text of the auth check is not read programmatically; the UI keys off `ADAPTER_AUTH_MISSING_CHECK_CODE`. Rows without the managed marker render exactly as before. ## What Changed - New `environmentDisplayLabel` helper in `ui/src/lib/managed-sandbox-environment.ts`: managed rows → name alone; other rows → "Name · driver". - `AgentConfigForm`: inherited-default label uses the helper; fallback copy "Managed sandbox" → "Paperclip Computer"; environment options use the helper. - `ProjectProperties`, `CompanyEnvironments`: environment selector options use the helper; the environments-list row hides the driver suffix on managed rows; the managed detail page's fallback description no longer says "sandbox". - `Agents` page: managed environments are described as "Managed by Paperclip" instead of "<provider> sandbox provider". - `CommentThread` run details: the driver suffix is omitted for sandbox-driver environments. - claude-local and codex-local adapters: auth-missing check message/hint reworded from "sandbox" to "environment" (ACP and environment-test paths); claude-local probe/effort/login hints reworded the same way. - Run status lines: "Syncing workspace to sandbox", "Exporting git changes from sandbox", "Starting adapter in sandbox", and friends now say "environment"; "Finalizing sandbox workspace" → "Finalizing workspace". Templated transfer-progress lines map the `sandbox` transport key to "environment" for display (`runtime-progress.ts`). - Agent form sign-in panel: "Sign in to the sandbox" → "Sign in to the environment"; "Authenticated. The sandbox has credentials now." → "…The environment has credentials now." - Feature catalog + instance settings card: "Managed Sandbox Only" → "Managed Environment Only" (setting key unchanged; the card keeps its alphabetical slot). - Server agents routes: execution-target failure and test-identity copy no longer say "sandbox"; workspace-mode label "Cloud sandbox" → "Cloud environment". - Tests: new `environmentDisplayLabel` unit cases; new `AgentConfigForm` render case asserting the managed default renders without "(sandbox)" or "· sandbox"; status-line assertions updated across adapter-utils, server heartbeat/live-run, and UI chat suites. ## Verification - `pnpm --filter @paperclipai/ui typecheck` — clean. - `pnpm --filter @paperclipai/adapter-claude-local typecheck` and `--filter @paperclipai/adapter-codex-local typecheck` — clean. - `vitest run` for `managed-sandbox-environment.test.ts`, `AgentConfigForm.render.test.tsx`, `CompanyEnvironments.test.tsx`, `Agents.test.tsx`, `CommentThread.test.tsx`, `NewAgent.test.tsx` — all green (118 tests across the two runs). ## Risks Low risk. Cosmetic label changes only; no data or API changes. Rows without `metadata.managedByPaperclip` render exactly as before, so self-hosted deployments with their own environments see no change.

feat(environments): refer to the managed default environment by name, not the sandbox driver key (#11838 )

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Managed deployments provision a platform-managed default environment
for agent runs; the UI shows this environment in selectors, the agent
form, run details, and the environments page
> - Those surfaces append the raw driver key to the environment name, so
users see labels like "Paperclip Computer (sandbox)", "Paperclip
Computer · sandbox", and fallback copy such as "Managed sandbox" and
"The sandbox has no ready authentication"
> - "sandbox" is infrastructure vocabulary, not the product name of the
environment; showing it next to the managed environment's name is
confusing and off-brand
> - This pull request renders platform-managed environments by name
alone and rewords the sandbox-phrased copy, while user-created
environments keep the driver suffix so mixed lists stay distinguishable
> - The benefit is that the default environment reads as one clear
product name everywhere, and self-hosted users lose nothing: their own
environments still show the driver

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Display of the platform-managed default environment across the UI.

**Subsystem affected**

UI (environment selectors, agent config form, environments page, agents
page, run details) and the claude-local/codex-local adapter auth checks.

**Current behavior**

The agent form labels the inherited default environment as "Name
(sandbox)". Environment selectors and the environments list render "Name
· sandbox". The agents page describes the environment as "<provider>
sandbox provider". The agent form's fallback label is "Managed sandbox".
Adapter auth checks say "The sandbox has no ready authentication for
this adapter."

**Proposed behavior**

Platform-managed environment rows (`metadata.managedByPaperclip`) render
their name alone. The fallback label is "Paperclip Computer". The agents
page describes managed environments as "Managed by Paperclip". Run
details omit the driver suffix for sandbox-driver environments (the
adjacent Provider entry already identifies the mechanism). Adapter auth
checks say "This environment has no ready authentication for this
adapter."

**Reason and benefit**

The managed environment carries a product name. Appending the raw driver
key ("sandbox") to it is noise and contradicts the product naming.
User-created environments keep the driver suffix, so mixed lists stay
distinguishable.

**Breaking changes**

None. Message text of the auth check is not read programmatically; the
UI keys off `ADAPTER_AUTH_MISSING_CHECK_CODE`. Rows without the managed
marker render exactly as before.

## What Changed

- New `environmentDisplayLabel` helper in
`ui/src/lib/managed-sandbox-environment.ts`: managed rows → name alone;
other rows → "Name · driver".
- `AgentConfigForm`: inherited-default label uses the helper; fallback
copy "Managed sandbox" → "Paperclip Computer"; environment options use
the helper.
- `ProjectProperties`, `CompanyEnvironments`: environment selector
options use the helper; the environments-list row hides the driver
suffix on managed rows; the managed detail page's fallback description
no longer says "sandbox".
- `Agents` page: managed environments are described as "Managed by
Paperclip" instead of "<provider> sandbox provider".
- `CommentThread` run details: the driver suffix is omitted for
sandbox-driver environments.
- claude-local and codex-local adapters: auth-missing check message/hint
reworded from "sandbox" to "environment" (ACP and environment-test
paths); claude-local probe/effort/login hints reworded the same way.
- Run status lines: "Syncing workspace to sandbox", "Exporting git
changes from sandbox", "Starting adapter in sandbox", and friends now
say "environment"; "Finalizing sandbox workspace" → "Finalizing
workspace". Templated transfer-progress lines map the `sandbox`
transport key to "environment" for display (`runtime-progress.ts`).
- Agent form sign-in panel: "Sign in to the sandbox" → "Sign in to the
environment"; "Authenticated. The sandbox has credentials now." → "…The
environment has credentials now."
- Feature catalog + instance settings card: "Managed Sandbox Only" →
"Managed Environment Only" (setting key unchanged; the card keeps its
alphabetical slot).
- Server agents routes: execution-target failure and test-identity copy
no longer say "sandbox"; workspace-mode label "Cloud sandbox" → "Cloud
environment".
- Tests: new `environmentDisplayLabel` unit cases; new `AgentConfigForm`
render case asserting the managed default renders without "(sandbox)" or
"· sandbox"; status-line assertions updated across adapter-utils, server
heartbeat/live-run, and UI chat suites.

## Verification

- `pnpm --filter @paperclipai/ui typecheck` — clean.
- `pnpm --filter @paperclipai/adapter-claude-local typecheck` and
`--filter @paperclipai/adapter-codex-local typecheck` — clean.
- `vitest run` for `managed-sandbox-environment.test.ts`,
`AgentConfigForm.render.test.tsx`, `CompanyEnvironments.test.tsx`,
`Agents.test.tsx`, `CommentThread.test.tsx`, `NewAgent.test.tsx` — all
green (118 tests across the two runs).

## Risks

Low risk. Cosmetic label changes only; no data or API changes. Rows
without `metadata.managedByPaperclip` render exactly as before, so
self-hosted deployments with their own environments see no change. The
only self-hosted-visible wording changes are the adapter auth-check
message and the driver suffix omission on sandbox-driver rows in run
details.

extended thinking, tool use.

Let tenants edit env vars on managed sandbox environments; add managed-sandbox-only mode (#11200 )

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Environments give each agent run an execution target: the local
host, SSH, or a sandbox provider
> - A managed deployment can provision one platform-managed sandbox
environment through the `PAPERCLIP_MANAGED_CONFIG` `environments`
section
> - That row is fully locked today. A tenant cannot add environment
variables for their agents. There is also no way to hide local execution
— run selection falls back to the local row
> - A platform that manages the sandbox for its tenants needs both: the
tenant adds env vars (and nothing else), and local execution is neither
visible nor reachable
> - This pull request opens exactly one tenant edit (env vars) on the
managed sandbox row, and adds an `enableManagedSandboxOnly` mode that
hides local and makes run selection fail closed
> - The benefit is a complete managed-sandbox experience with no change
for self-hosted instances

## Linked Issues or Issue Description

**Subsystem affected**

Environments (managed sandbox provisioning, environment routes, run
environment selection) and the environments UI.

**Problem or motivation**

Platform-provisioned sandbox environments
(`metadata.managedByPaperclip`) reject every write on cloud-managed
instances. Agents often need environment variables inside their sandbox.
The tenant has no way to set them on the managed row. Separately, an
operator cannot remove local execution: the environment list always
shows the local row, and run selection falls back to it when no default
is set.

**Proposed solution**

Allow an envVars-only PATCH on the managed sandbox row, and echo those
env vars back for editing. Add a managed-tier feature
(`enableManagedSandboxOnly`) that hides the local environment from all
read surfaces and redirects local-landing run selection to the managed
sandbox environment, failing closed when it is unavailable.

**Alternatives considered**

UI-only hiding of the local row. This was rejected: it does not stop a
run from resolving to local, so it is presentation without enforcement.
Full unlock of the managed row was also rejected: name, driver, and
config stay platform-owned so boot reconciliation cannot fight tenant
edits.

## What Changed

- `server/src/routes/environments.ts`: the platform-provisioned write
floor admits an envVars-only PATCH on the generalized managed sandbox
row (sandbox driver, `managedByPaperclip`, not legacy kubernetes-marker
rows). Name, driver, config, status, metadata, and DELETE stay rejected.
The read floor stops blanking env vars on that row; credential-shaped
config keys stay redacted for every actor. Legacy kubernetes-marker rows
keep the full floor.
- Same file: under `enableManagedSandboxOnly`, the environments list and
the by-id read omit the local row for every actor, including instance
admins.
- `server/src/services/execution-workspace-policy.ts`:
`resolveExecutionWorkspaceEnvironmentId` gains the managed-sandbox-only
inputs. A selection that lands on the local environment is redirected to
the managed sandbox environment. With no active managed row it throws
`ManagedSandboxUnavailableError` — never local. Non-local selections
(ssh, user-created sandboxes) are untouched.
- `server/src/services/heartbeat.ts`: the run path reads the flag, looks
up the managed row (`findManagedSandboxEnvironment`, new read-only
finder in `environments.ts`), and passes both to the resolver. Mirrors
the forced-kubernetes precedent, which keeps precedence when both
regimes are on.
- `server/src/services/managed-environments.ts`: after a successful
reconcile, the instance default environment moves to the managed sandbox
row when the current default is unset, local, or dangling. A
tenant-chosen custom environment is never overridden.
- `packages/shared`: new `enableManagedSandboxOnly` key (schema default
false, catalog tier `managed`, cloudDefault false, selfHostedDefault
false) and the matching interface field.
- UI: managed rows show a "Managed by Paperclip" lock badge; editing one
opens a dedicated env-vars-only editor that sends the one PATCH shape
the server admits (the old full form failed with a 403 on save). New
`ui/src/lib/managed-sandbox-environment.ts` mirrors the local filter for
cached lists (applied in the project picker; the agent picker already
excluded local). The experimental settings page gains the toggle at its
alphabetical card position. `environmentsApi.update` now declares the
`envVars` field it already sent.
- Tests: environment route floor coverage (envVars-only accepted, mixed
bodies rejected, legacy rows still blanked and locked, local hidden and
404 under the flag, self-hosted unchanged), an embedded-postgres service
test pinning that boot reconciliation never touches tenant env vars,
resolver redirect/fail-closed cases, managed-environments
default-stamping cases, and UI lib/settings tests.

## Verification

- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/environment-routes.test.ts
src/__tests__/environment-service.test.ts
src/__tests__/execution-workspace-policy.test.ts
src/services/managed-environments.test.ts` — all pass.
- `pnpm --filter @paperclipai/shared exec vitest run` — 425 pass
(catalog/schema default parity is pinned by an existing test).
- `pnpm --filter @paperclipai/ui exec tsc --noEmit` and the affected UI
suites (CompanyEnvironments, InstanceExperimentalSettings incl.
card-order test, new lib test) — all pass.
- Full workspace `pnpm test`: 3,414 passed. 17 files report failures on
this machine; the identical 17 fail on a clean `origin/master` worktree
in the same environment (git-worktree/skills/embedded-postgres
environment dependencies and plugin-SDK zero-test collections). One
additional file (`issue-monitor-scheduler.test.ts`) failed one
timing-sensitive test in one of two full-suite runs and passes 7/7 in
isolation on this branch — a flake in a domain this diff does not touch.
The branch introduces no new failures.
- Self-hosted zero-delta: every new behavior is gated on the
cloud-managed instance check or the new flag, which defaults to false in
schema and catalog; pinned by the "does not floor platform-marked rows
on self-hosted instances" and flag-off tests.

## Risks

- Behavior is opt-in twice over: the write-floor exception applies only
to rows the managed-config provisioner stamps, and the hiding/forcing
applies only when `enableManagedSandboxOnly` is on (default false
everywhere). Self-hosted instances see no change.
- The env-vars echo is scoped to the generalized managed sandbox row;
legacy kubernetes-marker rows keep the blanket floor because
pre-generalization builds may have written platform values there.
- Fail-closed run selection means a managed instance with the flag on
and an archived managed row (provider plugin down) refuses runs with a
precise error instead of running locally. That is the intended posture.
