> **Stacked pull request.** This targets #11524. Merge #11524 first.
Review only the second commit, `feat(runtime): managed Tailscale HTTPS
lifecycle...`.
## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip starts and supervises managed runtime services, so an
agent's branch can be previewed while the agent works
> - The previous pull request added the host broker, the shared
contract, and the database columns, but no code used them
> - A managed runtime can only be exposed over HTTPS if it holds a
stable loopback port pair for the whole life of the service. The current
control path cannot promise this: two controls can race the same
execution workspace, a stranded control can stay `running` forever, and
a start can adopt a port it does not own
> - This pull request adds the HTTPS lifecycle and the control-path
hardening that the lifecycle depends on
> - The benefit is that a managed preview becomes reachable from another
device, and a managed control now always reaches a terminal state
## Linked Issues or Issue Description
No public GitHub issue exists. The change follows the feature request
template.
**Subsystem affected**
Managed workspace runtime services, workspace operations, the execution
workspace routes, and the workspace runtime UI.
**Problem or motivation**
A managed runtime service is reachable only on loopback, so a preview
cannot be opened from a phone or a second computer. Exposing it safely
needs an exclusively held port pair. Three existing gaps block that.
Overlapping controls can race the same workspace. A control whose owner
dies stays `running` and blocks the lane forever. Port allocation does
not confirm that the process holding a port is the process Paperclip
spawned.
**Proposed solution**
Add the exposure lifecycle on top of the broker from #11524: reserve
before spawn, expose after readiness, validate the public URL, and
remove on stop. In the same change, make managed controls mutually
exclusive per workspace, give each control a durable issue-owned lease
and a terminal state, and verify port ownership before use.
**Alternatives considered**
- Add HTTPS exposure without the control hardening. This was rejected
because a raced or stranded control makes exposure point at the wrong
process.
- Guard the lane with an in-memory lock only. This was rejected because
the lock does not survive a server restart, so the lane can be lost or
double-claimed.
- Trust the requested bind address. This was rejected because a checkout
that predates managed HTTPS overwrites `PAPERCLIP_BIND` from its own
`--bind` argument, and then binds the wildcard address.
**Roadmap alignment**
This completes the managed workspace runtime capability that already
exists. It adds no new product surface beyond the HTTPS link.
**Additional context**
This is the second of three pull requests. The third adds central
mediation of leased port pairs.
## What Changed
Exposure lifecycle:
- Add the server-side broker client and the exposure lifecycle manager.
The manager reserves the mapping before spawn, exposes after backend
readiness, validates the public URL, and removes the mapping on stop.
- Default managed worktree runtimes to `tailscale_https`, read exposure
intent from legacy `expose` blocks, and backfill runtimes that are still
HTTP-only.
- Verify listener ownership for the app port and its Vite HMR companion
before the broker is asked to expose anything. An unrelated listener on
either port fails the start closed.
- Force the loopback bind through argv instead of environment hints.
Leave a non-Paperclip service's `--bind` argument alone.
- Probe loopback for readiness instead of the public URL, and give Vite
HMR its own loopback-bound server in middleware mode.
- Preserve operator-declared Serve mappings across the managed
lifecycle, so cleanup never removes a mapping that Paperclip did not
create.
- Name which listener predicate denied an expose, so an operator can act
on the message.
Control-path hardening:
- Make `start`, `stop`, `restart`, and job `run` mutually exclusive per
execution workspace. An overlap gets `409
workspace_runtime_control_in_progress`, and authorization is still
checked first.
- Take a durable exclusivity lease on the execution workspace, owned by
the controlling issue. A different issue gets `409
workspace_runtime_lease_conflict` before any operation is recorded.
Board and operator actions bypass the lease.
- Give every control a terminal state. Each control stamps its owning
process and pid, heartbeats while it runs, and has a wall-clock ceiling.
Recovery of a stranded control uses a compare-and-swap on `updated_at`,
so a live owner is never stolen.
- Bound readiness probes, verify allocated port ownership on POSIX and
Windows, harden sibling port allocation, and reconcile desired runtimes
on server startup.
- Surface exposure state and bounded runtime errors in the workspace
runtime UI.
- Record the new behavior in `doc/DEVELOPING.md`.
## Verification
Focused checks, all run on this branch:
- `npx tsc --noEmit -p server/tsconfig.json` — 139 errors, exactly the
count on `master`. All 139 come from the unbuilt
`@paperclipai/plugin-sdk` package.
- `pnpm --filter @paperclipai/ui typecheck` — clean.
- Server suites, 177 tests pass across 9 files:
`workspace-runtime.test.ts`, `workspace-runtime-leases.test.ts`,
`workspace-runtime-control-recovery.test.ts`,
`execution-workspace-runtime-control-conflict.test.ts`,
`execution-workspace-runtime-lease-route.test.ts`,
`workspace-operations-reconciliation.test.ts`,
`workspace-runtime-start-terminality.test.ts`, `app-hmr-port.test.ts`,
and `workspace-runtime-ready-comment.test.ts`.
- Exposure unit suites, 77 tests pass: `src/services/runtime-exposure/`
and `workspace-runtime-exposure-backfill.test.ts`.
- UI: `WorkspaceRuntimeControls.test.tsx` and
`WorkspaceServiceControlBar.test.tsx` — 34 tests pass.
**One suite is red on the development host and is expected to be green
in CI.** `server/src/services/workspace-runtime-exposure.test.ts` has 10
failures on the machine used to write this branch. The cause is host
contamination, not the code. That machine already runs an HTTPS canary
that holds ports 42000, 42001, 52000, and 52001 on a tailnet address.
The suite allocates from the same range, so the new listener-ownership
check correctly reports:
```
listener_ownership_mismatch — port 42000 is bound to 100.123.243.20, 127.0.0.1,
fd7a:115c:a1e0:0:0:0:dd3a:f314 ... instead of loopback only
```
A CI runner has no listener on those ports, so the check sees loopback
only and the suite passes. Please confirm this from the CI result on
this pull request rather than from a local run on a host that already
exposes a managed runtime. This is a real weakness of the current test
fixture, and the third pull request in the series removes it by
allocating the pair through a central mediator instead of a stubbed
availability check.
`workspace-runtime-https-live-exercise.test.ts` needs a live `tailscale`
host and was not run locally.
## Risks
- This is the behavior-bearing pull request of the three, so it carries
the most risk.
- Two new `409` responses appear on managed control routes. A caller
that assumed a control always starts must handle a conflict. Board and
operator actions are deliberately exempt, so an agent lease cannot lock
an operator out.
- Managed worktree runtimes now default to `tailscale_https`. If the
host has no working broker, the start fails closed and reports the
exposure failure instead of silently serving plain HTTP. This is
intended, and it is the reason the failure message names the denying
predicate.
- Startup reconciliation touches persisted runtime rows. It is scoped to
desired state and does not resurrect a service that never came up.
- The lease has a 30-minute time to live and explicit release paths, so
a crashed owner cannot hold a lane forever.
- No migration runs in this pull request. The tables and columns land in
#11524.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Operators often open self-hosted Paperclip over plain HTTP on a LAN
or private network.
> - Browser Clipboard API writes are not reliable in that insecure
context.

but many current copy actions bypass it.

first-party workspace-diff plugin through the shared helper.
> - The benefit is consistent copy behavior on HTTPS, localhost, and
plain-HTTP private deployments.
## Linked Issues or Issue Description
Refs #3529.
This change supersedes the stale prior attempt in #3531. Current master
has more copy surfaces and a first-party plugin UI bridge that the prior
branch does not cover.
## What Changed
- Replaced direct Clipboard API writes and duplicate fallback
implementations across the current core UI with `copyTextToClipboard`.
- Added an HTTP-safe clipboard function to the plugin UI SDK and wired
the host bridge to the same implementation.
- Migrated the first-party workspace-diff plugin to the plugin SDK
clipboard function.
- Added unit coverage for native rejection fallback and plugin host
delegation.
- Added a source-level regression test that rejects new direct clipboard
writes outside the shared implementation.
- Documented the plugin UI clipboard function.
## Verification
- `NODE_ENV=test pnpm exec vitest run ...` for 14 affected suites: 164
tests passed.
- `pnpm exec vitest run tests/ui-clipboard.test.ts` in
`packages/plugins/sdk`: 1 test passed.
- `NODE_ENV=test pnpm -r typecheck`: passed for 31 workspace projects.
- `NODE_ENV=test pnpm test:run`: passed.
- `NODE_ENV=production pnpm build`: passed.
- `pnpm check:token-gates`: passed with all gates clean.
## Risks
Low risk. Secure contexts still use the modern Clipboard API. Plain HTTP
and rejected modern writes use the existing `execCommand("copy")`
fallback. That API is deprecated, but it is the compatibility path
required for insecure contexts. The change has no schema, API, or visual
design effect.

## Model Used
OpenAI Codex, `gpt-5.6-sol`. The runtime did not expose a context-window
size. Reasoning, tool use, repository editing, test execution, and
GitHub CLI access were enabled.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Isolated workspaces give each task a safe and reproducible checkout.
> - The existing setup cloned the development database before an agent
needed to run the app.
> - This made worktree creation slower and heavier for tasks that never
start a service.
> - Runtime services already use one server start path for heartbeat,
operator, and startup recovery flows.
> - This pull request moves heavy setup to that start path and keeps
worktree creation lean.
> - The benefit is faster isolated workspace creation with the same
reliable runtime setup when a service starts.
## Linked Issues or Issue Description
Related pull request: #10652 covers the initial deferred
database-seeding slice. This pull request supersedes it with end-to-end
runtime provisioning and safe cleanup.
**What existing behavior does this improve?**
This improves isolated worktree creation, runtime service startup, and
isolated instance cleanup.
**Subsystem affected**
Cross-cutting: CLI worktree setup, server runtime orchestration, shared
workspace contracts, and development scripts.
**Current behavior**
Paperclip seeds an isolated development database during worktree
creation. It can also leave an isolated instance directory after
workspace teardown. This work happens even when no runtime service
starts.
**Proposed behavior**
Paperclip creates the worktree with a lean eager setup. It runs an
idempotent runtime provision command before the first managed service
spawn. Concurrent starts share one provision attempt. Teardown removes
the isolated instance safely.
**Reason and benefit**
Many agent tasks only edit and test code. They do not need a running
Paperclip instance. Deferring the database seed reduces workspace
startup cost while preserving automatic setup for tasks that start the
app.
**Breaking changes**
None. The new runtime provision command is optional. Existing workspace
behavior is unchanged when it is absent.
## What Changed
- Split Paperclip worktree setup into a lean eager script and an
idempotent runtime provision script.
- Added `runtimeProvisionCommand` to project, issue, realized workspace,
and persisted workspace contracts.
- Added a per-workspace provision mutex before local service spawn for
heartbeat, operator, and startup recovery flows.
- Added a persisted `provisioning` service state and the
`workspace_runtime_provision` operation phase.
- Kept provision time outside the service readiness timeout and made
failed attempts visible and retryable.
- Reclaimed isolated instance data during safe workspace teardown.
- Serialized deferred database seeding across processes and bound
teardown to the instance root captured in persisted workspace metadata.
- Added tests for config flow, concurrency, retry, no-op behavior,
readiness timing, scripts, CLI commands, and cleanup.
- Documented the eager and runtime provisioning contracts.
## Verification
- `pnpm -r typecheck`
- `pnpm build`
- `pnpm test:run` (server: 3,201 passed; UI: 3,345 passed; the CLI phase
exposed one environment-sensitive AWS doctor assertion because the agent
runtime injects static AWS credentials)
- `env -u AWS_ACCESS_KEY_ID -u AWS_SECRET_ACCESS_KEY pnpm exec vitest
run cli/src/__tests__/secrets.test.ts -t 'passes AWS doctor checks when
non-secret provider config is present'`
- Focused runtime tests cover serialized provisioning, retry after
stderr failure, absent-command no-op behavior, operation logging,
persisted state order, and readiness timeout exclusion.
- Focused CLI and cleanup tests cover concurrent seed serialization,
stale-lock fail-closed behavior, persisted instance ownership, and
rewritten sibling pointers.
## Risks
- A faulty runtime provision script blocks service startup. Paperclip
records stderr, marks the service failed, and retries on the next start.
- Concurrent service requests share an in-process provision attempt,
while the seed command uses an atomic filesystem lock across processes.
A stale lock fails closed and requires an operator to verify no seed is
running before removing it.
- Isolated instance cleanup is destructive. The cleanup service
validates ownership and path containment before removal.

## Thinking Path
> - Paperclip is the open source control plane people use to coordinate
AI-agent work.
> - Execution workspaces provide the local service loop where operators
start, stop, restart, inspect, and open workspace services.
> - The existing header exposed those actions through separate controls
whose position and labeling changed across runtime states.
> - That movement made the most common development actions harder to
scan and easier to misclick, especially with multiple services or long
URLs.
> - The design therefore uses one fixed-geometry, state-aware control
bar and keeps service-specific detail behind a compact disclosure.
> - This pull request adds that control surface, maps existing runtime
data and every pending mutation into it, and integrates it into the
execution-workspace header without changing server contracts.
> - The benefit is a calmer, predictable service-control loop across
stopped, transitional, running, unhealthy, failed, multi-service, and
narrow-width states.
## Linked Issues or Issue Description
### Subsystem affected
`ui/ — React + Vite board UI`
### Problem or motivation
Execution-workspace service actions move and change shape as runtime
state changes, while URLs and multi-service status compete for header
space. During bulk actions, operators also need every targeted service
to show its transitional state immediately.
### Proposed solution
Use one fixed-geometry, state-aware service control bar in the workspace
header. Map existing runtime records into a stable status, URL, and
actions model, and track each in-flight bulk request independently until
it settles.
### Alternatives considered
Keeping the separate quick-control buttons was rejected because their
geometry changes by state. Showing every service inline was rejected
because it makes the header too wide; per-service detail remains in a
compact disclosure and the Services tab.
### Roadmap alignment
Reviewed `ROADMAP.md`; this focused execution-workspace UI improvement
does not duplicate a listed roadmap initiative.
### Additional context
The published design and state viewer is available at
https://pages.paperclip.ing/pap-14233-workspace-service-controls/.
## What Changed
- Added `WorkspaceServiceControlBar`, a fixed-geometry responsive
control for single- and multi-service runtime states.
- Added 15 Storybook states covering running, stopped, transitions,
unhealthy, failed, disabled, long-URL, mobile, and multi-service
behavior.
- Replaced `WorkspaceRuntimeQuickControls` in the execution-workspace
header with adapters that map live services and all pending requests
into the new control model.
- Added focused unit coverage for service-entry construction, bulk
pending overlays, request resolution, clipboard feedback, and header
integration.
## Verification
- `cd ui && NODE_ENV=development pnpm vitest run
src/components/WorkspaceServiceControlBar.test.tsx
src/components/WorkspaceRuntimeControls.test.tsx
src/pages/ExecutionWorkspaceDetail.test.tsx` — 29 tests passed.
- `NODE_ENV=development pnpm --dir ui typecheck` — passed.
- `pnpm check:token-gates` — all token gates clean.
- Reviewed the Storybook captures for all primary states.
## Risks
- Low-to-moderate UI risk: service controls depend on adapter mapping
from existing runtime records; focused tests cover single-service and
bulk-action mapping and integration paths.
- Multi-service bulk actions intentionally apply to all eligible
services, while per-service actions remain in the disclosure.
