## Linked Issues or Issue Description
**What happened?**
A pull request preparation run could not pin its execution workspace to
an exact existing branch. Workspace reuse and cleanup could also confuse
worktree creation with branch ownership.
**Expected behavior**
The run must attach only to the requested branch in an isolated Git
worktree. It must fail if the branch is missing, busy, or inconsistent.
Cleanup must not delete a branch that Paperclip does not own.
**Steps to reproduce**
1. Create a branch that contains completed work.
2. Configure a pull request preparation task to use that branch.
3. Start the task and observe that the prior policy cannot require the
exact branch.
**Paperclip version or commit**
This behavior reproduces on the base revision before this pull request.
**Deployment mode**
Local development with isolated Git worktrees.
## What Changed
- Add `existingBranch` to the execution workspace policy and shared
validation contracts.
- Require `existingBranch` to use an isolated Git worktree and reject
conflicting branch templates.
- Attach to the exact branch without creating, renaming, resetting, or
deleting it.
- Track branch ownership separately from worktree creation and use that
ownership during cleanup.
- Return HTTP 422 for invalid existing-branch settings on every
issue-producing route.
- Add a bounded repair script for existing pull request preparation
tasks.
- Add focused policy, route, heartbeat, runtime, and ready-comment
tests.
- Document the exact-branch behavior and safety rules.
## Verification
- `pnpm exec vitest run
server/src/__tests__/execution-workspace-policy.test.ts
server/src/__tests__/heartbeat-workspace-session.test.ts
server/src/__tests__/issue-existing-branch-validation-status.test.ts
server/src/__tests__/workspace-runtime.test.ts
server/src/services/workspace-runtime-exposure.test.ts
server/src/services/workspace-runtime-ready-comment.test.ts` passed 335
tests.
- `pnpm -r typecheck` passed for all workspace projects.
- `pnpm test:run` passed 4,431 tests. Two unrelated embedded-Postgres
setup hooks timed out under aggregate load. Their isolated rerun passed
74 tests.
- `pnpm build` passed for all workspace projects.
- The two review regressions passed with 139 unrelated tests skipped.
- All latest-head CI gates passed after one unrelated timing-sensitive
test passed on rerun.
- Greptile scored the latest head 5/5 with no unresolved review threads.
## Risks
- Invalid workspace settings now return HTTP 422 instead of a generic
validation response.
- The exact branch must already exist and must not be checked out by
another worktree.
- The new policy fails closed when it cannot prove branch identity or
ownership.
- This change has no database migration.

## 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.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The heartbeat service starts agent runs in local, SSH, sandbox,
plugin, or Kubernetes environments.
> - Runs can share one project working tree.
> - PR #10699 made every shared working tree single-file, including
trusted local and SSH hosts that support coordinated concurrent work.
> - Operators need a policy that keeps remote environments safe and
restores local multi-agent work.
> - This pull request adds an `auto`, `serialize`, or `allow`
concurrency policy and applies it to the final execution environment.
> - The benefit is safe serialization by default for sandboxed targets
and useful concurrency by default for persistent local targets.
## Linked Issues or Issue Description
Related work: #10699 introduced the busy gate that this change makes
configurable. #7852 covers a separate environment-lease race and does
not provide this dispatch policy.
**Subsystem affected**
`server/` heartbeat orchestration and `packages/shared/` workspace
policy contracts.
**Problem or motivation**
The shared-workspace busy gate always defers a second run. This behavior
prevents local multi-agent projects from running concurrently even when
operators expect agents to coordinate through commits.
**Proposed solution**
Add `sharedWorkspaceConcurrency` with `auto`, `serialize`, and `allow`
values. Default `auto` permits local and SSH concurrency. It serializes
sandbox, plugin, and forced Kubernetes execution.
**Alternatives considered**
Keeping unconditional serialization is too restrictive for persistent
host working trees. Always allowing overlap removes the protection that
sandboxed and remote targets need.
**Roadmap alignment**
This is a focused correction to the shipped cloud and sandbox execution
milestone. It does not add a new roadmap feature.
## What Changed
- Added the optional tri-state field to project policy and issue
override contracts and validators.
- Added a pure resolver with issue override, project policy, and `auto`
default precedence.
- Moved final environment and Kubernetes resolution before the
shared-workspace busy gate.
- Kept the existing deferral and retry behavior for every path that
resolves to serialization.
- Added a task-context warning and a structured log when a run
dispatches beside a live holder.
- Added policy and heartbeat coverage for all requested policy and
environment combinations.
- Documented the new policy and its default behavior.
## Verification
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/execution-workspace-policy.test.ts
src/__tests__/heartbeat-workspace-busy.test.ts` — 32 tests passed.
- `pnpm -r typecheck` — passed.
- `PAPERCLIP_IN_WORKTREE=false
PAPERCLIP_DATABASE_RESTORE_IN_PROGRESS=false
PAPERCLIP_RESTORE_IN_PROGRESS=false pnpm test:run` — all 3,528 server
tests passed. The later UI/workspace phase passed 3,384 tests and hit
one unrelated `CompanyEnvironments` navigation timing failure.
- `pnpm --filter @paperclipai/ui exec vitest run
src/pages/CompanyEnvironments.test.tsx -t "opens the edit form on a
standalone page with existing values and closes after save"` — the
unrelated UI test passed in isolation.
- `pnpm build` — passed.
Policy matrix:
| Policy | Final target | Expected result | Result |
| --- | --- | --- | --- |
| `auto` | local | Dispatch with holder note | Passed |
| `auto` | sandbox | Defer with `workspace_busy` | Passed |
| `auto` | instance-forced Kubernetes | Defer with `workspace_busy` |
Passed |
| `serialize` | local | Defer with `workspace_busy` | Passed |
| `allow` | sandbox | Dispatch with holder note | Passed |
Existing serialization, retry, and stale-holder tests also pass.
## Risks
- `auto` changes the post-#10699 local and SSH behavior back to
concurrent dispatch. Concurrent agents can mutate the same working tree,
so each dispatched run receives an explicit coordination warning.
- `allow` is an operator override and can permit overlap in sandbox or
plugin environments.
- Unknown environment drivers serialize in `auto` mode. This keeps the
fallback conservative.
- There is no database migration. An absent field resolves to `auto`.

## 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 app people use to manage AI agents for
work
> - Confinement providers protect agent runs with default-deny network
policies
> - Kubernetes environments currently apply only provider-level,
namespace-wide egress allowances
> - Tasks that legitimately need GitHub or package registries therefore
cannot request narrow access, while network failures do not explain the
governing policy or how to request a grant
> - This pull request adds issue-scoped egress grants that become
workload-owned, run-label-selected policies and carries the effective
grant through lease audit metadata
> - The benefit is that internet-dependent work can run without enabling
broad egress for every concurrent task, and denied requests point
operators to the exact grant path
## Linked Issues or Issue Description
No public issue exists. Related but distinct: Refs #9944, which adds a
provider-wide open-internet posture; this PR keeps provider defaults
narrow and adds per-task grants.
**Problem / motivation**
Kubernetes sandbox egress is configured at the provider/tenant level. A
task that needs to clone from GitHub or install from PyPI cannot request
those destinations without changing the policy for every run in the
tenant namespace. DNS/connectivity failures also surface as generic tool
errors with no policy name or remediation path.
**Proposed solution**
Accept `executionWorkspaceSettings.networkEgress.allowFqdns` and
`allowCidrs`, forward the setting through heartbeat environment
acquisition, and create a workload-owned NetworkPolicy or
CiliumNetworkPolicy selected by `paperclip.io/run-id`. Record the
effective grant in lease activity/metadata, expose policy context
through `PAPERCLIP_NETWORK_EGRESS_*`, and append the grant path to
likely policy-related stderr failures.
**Alternatives considered**
A provider-wide open-internet switch is broader than required and is
already covered by #9944. Mutating the existing namespace policy would
leak each task's destinations to other concurrent runs. Standard
Kubernetes NetworkPolicy cannot enforce FQDNs exactly, so standard mode
uses the existing hardened public-IPv4 TCP 80/443 fallback only for the
selected run; Cilium mode remains exact.
**Roadmap alignment**
This extends the existing cloud/sandbox agent roadmap capability with
task-level control-plane policy and does not duplicate a planned roadmap
item.
## What Changed
- Added validated `networkEgress` grants to issue execution workspace
settings and forwarded them through environment lease acquisition.
- Added workload-owned, run-label-scoped
NetworkPolicy/CiliumNetworkPolicy resources for task FQDN/CIDR grants.
- Added lease audit metadata, sandbox policy environment variables, and
actionable network-denial stderr guidance.
- Added focused parser, manifest, policy creation, and denial-message
tests plus Kubernetes provider documentation.
## Verification
- `pnpm -C packages/shared exec vitest run src/validators/issue.test.ts`
— 27 passed.
- `pnpm -C packages/plugins/sandbox-providers/kubernetes test -- --run
test/unit/network-policy.test.ts test/unit/cilium-network-policy.test.ts
test/unit/scoped-network-egress.test.ts` — 21 passed.
- `pnpm -C server exec vitest run
src/__tests__/execution-workspace-policy.test.ts` — 15 passed.
- `pnpm exec vitest run
server/src/__tests__/heartbeat-plugin-environment.test.ts
server/src/__tests__/environment-runtime.test.ts` — 26 passed.
- `pnpm --dir packages/db build && pnpm --dir packages/shared build &&
pnpm --dir packages/plugins/sdk build` — passed, including migration
safety checks.
- `pnpm --dir packages/plugins/sandbox-providers/kubernetes typecheck &&
pnpm --dir server typecheck` — passed after refreshing the worktree's
frozen offline dependencies.
- End-to-end cluster validation of the `build-cython-ext` benchmark
remains for CI/maintainer Kubernetes infrastructure; the focused tests
assert `github.com` and `pypi.org` produce a policy selected only by the
granted run.
## Risks
- Standard NetworkPolicy cannot express FQDNs, so an FQDN grant allows
hardened public IPv4 TCP 80/443 for that run; use Cilium mode for exact
hostname enforcement.
- The new field is additive and absent by default, so existing runs keep
the current provider-level policy.
- Workload owner references garbage-collect scoped policies with the
Job/Sandbox; a cluster/controller that ignores owner references could
temporarily strand a policy that still selects no future run ID.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents tackle complex tasks via *plan* flows: a planner decomposes
work into child issues, which are accepted by the board and then
executed
> - When a plan is accepted, `createChild` in `issues.ts` inserts child
issues pre-bound to the parent's already-realized execution workspace —
carrying over its concrete branch ref
> - If the repository's base ref advances between plan acceptance and a
child's first heartbeat, the child inherits a stale branch that no
longer matches the current base
> - At first heartbeat the workspace validator detects the mismatch and
freezes the child ("branch freeze"), blocking it from starting any work
> - The real fix is to strip the concrete workspace binding when
creating accepted-plan children: they should receive only the unresolved
*intent* (mode, baseRef, branchTemplate) and realize a fresh workspace
from the current base on their own first heartbeat
> - This PR implements that strip, adds a regression test that proves a
post-base-advance child realizes cleanly, and also fixes
`parseIssueExecutionWorkspaceSettings` so `environmentId` is not
silently dropped on update round-trips (a latent bug that was masking
the original fix)
## Linked Issues or Issue Description
No public GitHub issue exists for this bug. Bug description follows the
bug-report template:
**What happened:** Accepted-plan decomposition pre-binds child issues to
the parent's realized execution workspace branch (`executionWorkspaceId`
+ `executionWorkspaceBranch`). When `origin/master` advances between
plan acceptance and the child's first heartbeat, the workspace branch
interlock fires and the child is permanently frozen before it can start.
**Expected behavior:** Accepted-plan children should receive only
unresolved workspace intent (mode, git strategy fields) and realize a
fresh isolated worktree from the current base on first heartbeat. A
base-ref advance between acceptance and first-run should be transparent.
**Steps to reproduce:**
1. Accept a plan that decomposes into one or more child issues
(isolated_workspace + git_worktree mode).
2. Allow `origin/master` to advance (new merge).
3. Observe the first child heartbeat: workspace validation fails with a
branch-freeze error.
**Paperclip version:** current `master` (pre-fix).
**Deployment mode:** any (affects all modes that use isolated workspace
+ git worktree strategy).
Supersedes #9227 (earlier attempt, now closed — the fix was incomplete
because `environmentId` was silently dropped during
`parseIssueExecutionWorkspaceSettings` update round-trips, causing the
child workspace to lose its environment binding; this PR includes that
fix).
## What Changed
- **`server/src/issues.ts` — `createChild` / accepted-plan decomposition
path:** strip resolved workspace fields (`executionWorkspaceId`,
concrete branch) when creating accepted-plan children; preserve only
unresolved intent fields (`mode`, `baseRef`, `branchTemplate`,
`environmentId`, runtime/provisioning settings).
- **`server/src/execution-workspace-policy.ts` —
`parseIssueExecutionWorkspaceSettings`:** preserve `environmentId`
through update round-trips (was silently dropped, causing environment to
detach on any workspace settings update).
-
**`server/src/__tests__/heartbeat-accepted-plan-workspace-refresh.test.ts`:**
new regression test — accepted-plan child created after `origin/master`
moves realizes a fresh isolated worktree from the moved base and passes
workspace execution.
- **`server/src/__tests__/issues-service.test.ts`:** extended
workspace-linkage and `createChild` tests covering the accepted-plan
strip and the unchanged direct-child path.
## Verification
```sh
pnpm exec vitest run server/src/__tests__/heartbeat-accepted-plan-workspace-refresh.test.ts
pnpm exec vitest run server/src/__tests__/issues-service.test.ts -t "workspace linkage|accepted plan decomposition|createChild applies"
pnpm --filter @paperclipai/server typecheck
```
All three pass on this branch.
## Risks
**Low.** The change is scoped to the accepted-plan `createChild` code
path. The direct child / follow-up issue creation path (normal non-plan
decomposition) is unchanged and covered by existing tests. The
`parseIssueExecutionWorkspaceSettings` fix is additive — it now
preserves a field that was previously silently dropped, so no consumer
loses data.

## Thinking Path
> - Paperclip is an open-source platform for orchestrating AI agents;
agents run inside execution workspaces that range from a shared
container to full git worktrees cloned from a project repository.
> - Isolated git-worktree workspaces require a project to determine
which repository to clone — without a project the worktree base path
cannot be computed.
> - A task pinned to `isolated_workspace` + `git_worktree` with no
project was previously accepted at creation time but failed late at
dispatch with the opaque `workspace_validation_failed` /
`git_worktree_base_agent_home` error — only after the heartbeat
attempted to provision the workspace.
> - Fail-closed validation should happen in two places: (1) explicit
create/update pins that contradict the requirement are rejected at the
HTTP layer with a structured 422; (2) rows that reach the heartbeat
dispatcher with this invalid combination (e.g. through inheritance or a
retroactively-removed project) are blocked before any heartbeat run or
adapter spawn.
> - This PR adds the shared detection policy, the create/update guard in
the issues service, and the heartbeat pre-dispatch guard, together with
focused unit tests for all three layers.
> - The benefit is deterministic early failure with a clear remediation
message instead of a late, cryptic runtime error.
## Linked Issues or Issue Description
No upstream public GitHub issue — describing the problem inline
(bug-report format).
**What happened?**
Creating an issue with `executionWorkspaceSettings: { mode:
"isolated_workspace", type: "git_worktree" }` and no `projectId` was
accepted without error. The issue then became blocked at dispatch time
with the opaque message `git_worktree_base_agent_home` /
`workspace_validation_failed` — surfaced only after the heartbeat
attempted to provision the workspace.
**Expected behavior**
The platform should reject the invalid combination at create/update time
with a structured 422 that includes a clear remediation message, before
any heartbeat resource is consumed.
**Steps to reproduce**
1. Call `POST /api/issues` (or `PATCH /api/issues/:id`) with
`executionWorkspaceSettings: { mode: "isolated_workspace", type:
"git_worktree" }` and omit `projectId` (or set it to `null`).
2. Observe: request succeeds (200/201).
3. Assign the issue to an agent and watch it enter `blocked` with a
cryptic `workspace_validation_failed` error at dispatch.
**Related prior fix** — Refs #4844 (`fix(validator): reject static cwd
combined with git_worktree strategy`) — same validation area, different
dimension (static cwd vs. missing project).
**Paperclip version / commit**
Latest `master` (pre-this-PR).
**Deployment mode**
Standard (app-global server).
## What Changed
- **`execution-workspace-policy.ts`** — new shared
`detectWorkspaceWorktreeRequiresProject` function returning a stable
`workspace_worktree_requires_project` policy violation when an isolated
git-worktree task has no project, project workspace, or reusable
execution workspace; exports canonical remediation text used by both the
HTTP guard and the heartbeat guard.
- **`issues.ts`** — create and update paths check the new policy before
persisting; explicit pins to `isolated_workspace` / `operator_branch` +
`git_worktree` with no project are rejected with a 422 including the
policy code and remediation text.
- **`heartbeat.ts`** — pre-dispatch preflight checks the same policy for
rows that reach the heartbeat with the invalid combination (e.g. through
inheritance); such rows are marked `blocked` with a skipped wakeup
request, durable issue comment, and activity log before any heartbeat
run or adapter spawn.
- **`execution-workspace-policy.test.ts`** — focused policy-layer unit
tests for detection logic and remediation text.
- **`issues-service.test.ts`** — create/update 422 guard tests for the
new policy.
- **`heartbeat-workspace-branch-containment.test.ts`** — pre-dispatch
blocking test for inherited/ambiguous invalid rows; also fixes a cleanup
race in the existing test suite.
## Verification
```sh
pnpm exec vitest run \
server/src/__tests__/execution-workspace-policy.test.ts \
server/src/__tests__/issues-service.test.ts \
server/src/__tests__/heartbeat-workspace-branch-containment.test.ts
pnpm --filter @paperclipai/server typecheck
# Targeted regression
pnpm exec vitest run \
server/src/__tests__/heartbeat-workspace-branch-containment.test.ts \
-t "blocks projectless isolated git-worktree issues before dispatch"
```
All three test files and typecheck passed locally before this PR was
opened.
## Risks
**Low risk.** The policy detection function is pure with no side
effects. The create/update guard only triggers on explicit
`isolated_workspace` or `operator_branch` + `git_worktree` pins combined
with a missing project — it does not fire on inherited settings (handled
by the heartbeat preflight), so there is no false-positive rejection
risk for valid tasks. The heartbeat guard fires before any resource is
provisioned; the only behavioral change for already-invalid rows is that
they receive a clear `blocked` status and durable comment instead of a
late cryptic error.
## Model Used
Claude Sonnet 4.6 (`claude-sonnet-4-6`), 200k context window, tool use
enabled (agentic coding). Used to implement all server-side changes and

## Thinking Path
> - Paperclip is the control plane for AI-agent companies, so execution
environment selection has to stay inspectable and predictable across
companies, agents, and runs.
> - The environment subsystem decides where an agent heartbeat actually
runs and how remote sandbox state is realized and restored.
> - That subsystem previously mixed company-scoped environment catalogs
with issue-level environment stamping, so a reassigned issue could keep
executing in the previous assignee's sandbox.
> - That behavior breaks the control-plane contract: changing the
assignee should change the executing agent/environment path unless there
is an explicit current override.
> - Fixing it cleanly required more than a narrow patch; the environment
model had to move to instance scope with a single inherited default and
per-agent override semantics.
> - This pull request rewires the schema, server/API surface, runtime
resolution, and UI around that model, then adds regression coverage for
cross-company inheritance and per-agent isolation.
> - The benefit is that environment choice now follows the approved
instance/agent configuration path instead of stale issue state, while
shared environments only need to be configured once per instance.
## Linked Issues or Issue Description
- No directly matching public GitHub issue or PR was found while
searching for this refactor.
### What happened?
Reassigning work between agents with different execution environments
could keep running in the previous sandbox because environment choice
was stamped onto the issue and outranked the current assignee. The same
subsystem also forced environment catalogs to be duplicated per company
even though the underlying execution environments were instance-wide
resources.
### Expected behavior
Execution should resolve through the current instance and agent
configuration path, with one instance-scoped environment catalog, one
instance default, optional per-agent override, and no stale issue-level
environment authority surviving reassignment.
### Steps to reproduce
1. Configure two agents to use different execution environments.
2. Assign an issue to the first agent so the issue records execution
state in that environment.
3. Reassign the same issue to the second agent and run another
heartbeat.
4. Observe that the pre-fix runtime can still sync or execute in the
original sandbox instead of the second agent's environment.
### Paperclip version or commit
Current `master` before this PR.
### Deployment mode
Self-hosted server.
### Installation method
Built from source (`pnpm dev` / `pnpm build`).
### Agent adapter(s) involved
- Claude Code
- Not adapter-specific (core bug in environment authority / resolution)
### Database mode
External Postgres.
### Access context
Both board reassignment and agent heartbeats were involved.
## What Changed
- Moved environments and their default selection contract to instance
scope in DB/shared types, including the migration that dedupes legacy
per-company environments and seeds the instance local default.
- Reworked environment CRUD/auth flows to use instance-scoped APIs and
added route/service coverage for instance-level environment management.
- Changed runtime resolution to prefer `agent default -> instance
default -> built-in local`, removed issue-level environment stamping
from the active execution path, and isolated sandbox/plugin leases by
`(executionWorkspaceId, agentId)`.
- Added environment env-var runtime precedence so environment-provided
values act as the baseline for agent execution.
- Moved the environment UI into instance settings and updated agent
configuration surfaces to reflect inherit/override behavior.
- Added regression coverage for instance-default inheritance across
companies and for the new runtime resolution behavior.
- Fixed a rebase-only duplicate `enableTaskWatchdogs` flag regression in
instance settings types/validators/services so the branch typechecks
cleanly on current `master`.
- Updated stale server tests so CI matches the shipped instance-scoped
environment contract.
## Verification
- `git diff --check`
- `pnpm --filter @paperclipai/shared typecheck`
- `pnpm --filter @paperclipai/db typecheck`
- `pnpm exec vitest run
server/src/__tests__/environment-runtime-driver-contract.test.ts
server/src/__tests__/agent-permissions-routes.test.ts
server/src/__tests__/environment-routes.test.ts
server/src/__tests__/environment-instance-routes.test.ts
server/src/__tests__/execution-workspace-policy.test.ts
server/src/__tests__/heartbeat-plugin-environment.test.ts
server/src/__tests__/instance-settings-routes.test.ts`
## Risks
- The migration changes environment scope and dedupes existing rows, so
installs with unusual legacy environment combinations should be reviewed
carefully during upgrade.
- Remote execution behavior now depends on instance-default inheritance
semantics instead of issue-level stamping, so any remaining code paths
that still assume issue-scoped environment authority would surface as
follow-up bugs.
- This PR includes both server/runtime behavior and UI relocation, so
reviewers should watch for authorization edge cases around instance
settings and environment management.
> I checked [`ROADMAP.md`](ROADMAP.md). This work fits the existing
Cloud / Sandbox agents direction as a bug-fix/refactor to current
behavior, not a new parallel product surface.
## Model Used

tool-using model with code execution and shell access. The exact backend
model ID is not exposed to the session runtime.

## Thinking Path
> - Paperclip is a control plane for AI-agent companies, so execution
policy and trust boundaries are part of the product's safety contract.
> - Low-trust review work needs narrower authority than normal
same-company agents because hostile PRs, comments, attachments, and
generated output can carry prompt-injection payloads.
> - The current V1 shape gives trusted workers broad company context,
which is useful for normal execution but too permissive for a reviewer
assigned to hostile content.
> - This branch adds a `low_trust_review` preset, source-trust tagging,
route-level containment, and quarantine handling so low-trust output
does not automatically flow into higher-trust wake context.
> - The branch has been rebased onto current `origin/master`, and the
low-trust migration was renumbered to `0097_low_trust_source_trust.sql`
to avoid collisions with existing `0091` through `0096` migrations.
> - Greptile feedback was addressed by tightening low-trust detection,
preserving project-level trust policy checks, fixing issue-kind
promotion lookup, removing duplicate post-lease isolation assertion,
documenting fail-closed source-trust behavior, bounding ancestry checks,
enforcing runtime issue context for CEOs, awaiting accepted-plan monitor
authorization, and making low-trust issue source-trust tagging atomic.
> - The benefit is a first production slice of deny-by-default review
containment with regression coverage for the main control-plane pivot
surfaces.
Fixes#7531.
## What Changed
- Added shared trust-policy types and validators, plus
database/source-trust fields for issues, comments, documents, and work
products.
- Implemented server enforcement for low-trust issue scope, agent
self-view redaction, secret/plugin/runtime denial paths, promotion
checks, and quarantined continuation/wake context.
- Added focused low-trust regression tests for resolver behavior, source
trust, route authorization, heartbeat preflight ordering, runtime
containment, and quarantine redaction.
- Added board UI affordances for selecting/reviewing the low-trust
preset and surfacing source-trust badges in relevant issue views.
- Added `doc/LOW-TRUST-PRESETS.md`, updated
`doc/SPEC-implementation.md`, and committed the low-trust review
contract plan under `doc/plans/`.
- Rebasing note: the original `0097_low_trust_source_trust.sql`
migration was renamed to `0097_low_trust_source_trust.sql`; the SQL uses
`ADD COLUMN IF NOT EXISTS` so users who already applied the old-numbered
migration are not broken by the renumbered migration.
## Verification
- Rebased branch onto current `origin/master` and force-pushed with
lease to `origin/PAP-10211-low-trust-agent` at head `2719f31e3`.
- Confirmed the PR diff does not include `pnpm-lock.yaml` or
`.github/workflows` changes.
- Resolved upstream UI/comment conflicts by preserving deleted-comment
tombstone behavior and low-trust source-trust badges/metadata.
- Renumbered the low-trust source-trust migration to
`0097_low_trust_source_trust.sql`; the SQL uses `ADD COLUMN IF NOT
EXISTS` so users who already applied an old-numbered copy are not
broken.

- Greptile Review passes with Confidence Score 5/5 and zero unresolved
Greptile review threads.
- No design screenshots/images were added because the task explicitly
says not to add them unless they are specifically part of the work.
## Risks
- Medium risk: this touches shared trust-policy contracts, server
authorization paths, heartbeat context generation, migration metadata,
and UI preset controls.
- Low-trust containment is intentionally deny-by-default; legitimate
future review workflows may need explicit allowlisted exceptions.
- Plugin/runtime/security surfaces are broad, so regression tests cover
the current known routes but future integrations must route through the
same containment layer.
- The PR is ready for review; GitHub checks are green and Greptile is
5/5.

## Thinking Path
> - Paperclip orchestrates AI agents across isolated execution
workspaces; the local cwd is the only persistence boundary between runs.
> - Workspace lifecycle (worktree_prepare → execute →
workspace_finalize) and the wake/accept flow are what guarantee that
dependent issues see a consistent worktree.
> - PAPA-380 / PAPA-431 / PAPA-432 / PAPA-440 surfaced three holes in
that contract: silent env reuse across assignees, dependent wakes firing
before finalize, and `issue.interaction.accept` advancing before
finalize landed.
> - PAPA-441 / PAPA-442 then needed to document the "no remote git"
contract and prevent future adapter/runtime code from quietly
reintroducing `git push` as a backdoor sync.
> - This pull request lands those server fixes, the static
`check-no-git-push` enforcement, the AUTHORING.md cross-link, and the
Cody-review follow-ups on the PAPA-430 thread.
> - The benefit is that finalize is a real barrier — board accepts,
dependent wakes, and operator-set env all respect it — and adapter code
can't bypass it via raw `git push`.
## What Changed
- **server (PAPA-380, PAPA-431):** `execution-workspace-policy` refuses
silent env reuse when the assignee's resolved env disagrees with the
workspace it would inherit. The inheritance protection is now scoped to
the actual inheritance signal — explicit issue-level `environmentId` is
honored even when the agent's default env is `null`.
- **server (PAPA-432):** `heartbeat.ts` gates dependent wakes on
`listUnfinalizedExecutionWorkspaceIds`, and writes a
`workspace_finalize` row on the succeeded path. Write failures now
surface instead of being swallowed so dependents aren't silently
stranded behind a missing row.
- **server (PAPA-440):** `issue-thread-interactions.acceptInteraction`
adds a workspace_finalize precondition for `request_confirmation` (not
`suggest_tasks`). Accept returns 409 if finalize hasn't succeeded for
the latest workspace operation.
- **ci (PAPA-442):** new `scripts/check-no-git-push.mjs` static check
scans `packages/adapters/`, `packages/adapter-utils/`, `server/src/`,
and `cli/src/` for any `git push` invocation (string or args-array).
Wired into the `policy` PR job and `test:release-registry`. Operators
can opt in per-call with `// paperclip:allow-git-push: <reason>`.
Release scripts are out of scope by design.
- **docs (PAPA-441):** `AUTHORING.md` documents the no-remote-git
contract and cross-links the static check so adapter authors learn the
rule and the enforcement together.
- **review follow-up (PAPA-430, Cody):** three fixes — env resolver bug,
accept-gate scope (request_confirmation only), and finalize record write
on the succeeded path.
## Verification
- `pnpm exec vitest run
server/src/__tests__/execution-workspace-policy.test.ts
server/src/__tests__/issue-thread-interactions-service.test.ts` → 33/33
pass
- `node scripts/check-no-git-push.test.mjs` → check covers string form,
args-array form, comment exclusions, and per-line allow-comment.
- Manual: server compiles; the policy job runs the check in <1s before
heavier jobs.
## Risks
- **Behavioral shift in accept:** boards accepting
`request_confirmation` while finalize is in-flight now get 409s. This is
intentional — they can retry — but it changes timing on a hot path.
`suggest_tasks` is unaffected.
- **Workspace policy:** the env-reuse refusal is a new error path.
Issues that previously silently reused an env from a different-assignee
workspace will now fail-loud; the resolver still honors explicit
issue-level `executionWorkspaceSettings.environmentId`.
- **CI rule:** any future legitimate `git push` in scoped dirs must be
marked with the allow-comment, which is the intended ergonomic.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - The environments subsystem already models execution environments,
but before this branch there was no end-to-end SSH-backed runtime path
for agents to actually run work against a remote box
> - That meant agents could be configured around environment concepts
without a reliable way to execute adapter sessions remotely, sync
workspace state, and preserve run context across supported adapters
> - We also need environment selection to participate in normal
Paperclip control-plane behavior: agent defaults, project/issue
selection, route validation, and environment probing
> - Because this capability is still experimental, the UI surface should
be easy to hide and easy to remove later without undoing the underlying
implementation
> - This pull request adds SSH environment execution support across the
runtime, adapters, routes, schema, and tests, then puts the visible
environment-management UI behind an experimental flag
> - The benefit is that we can validate real SSH-backed agent execution
now while keeping the user-facing controls safely gated until the
feature is ready to come out of experimentation
## What Changed
- Added SSH-backed execution target support in the shared adapter
runtime, including remote workspace preparation, skill/runtime asset
sync, remote session handling, and workspace restore behavior after
runs.
- Added SSH execution coverage for supported local adapters, plus remote
execution tests across Claude, Codex, Cursor, Gemini, OpenCode, and Pi.
- Added environment selection and environment-management backend support
needed for SSH execution, including route/service work, validation,
probing, and agent default environment persistence.
- Added CLI support for SSH environment lab verification and updated
related docs/tests.
- Added the `enableEnvironments` experimental flag and gated the
environment UI behind it on company settings, agent configuration, and
project configuration surfaces.
## Verification
- `pnpm exec vitest run
packages/adapters/claude-local/src/server/execute.remote.test.ts
packages/adapters/cursor-local/src/server/execute.remote.test.ts
packages/adapters/gemini-local/src/server/execute.remote.test.ts
packages/adapters/opencode-local/src/server/execute.remote.test.ts
packages/adapters/pi-local/src/server/execute.remote.test.ts`
- `pnpm exec vitest run server/src/__tests__/environment-routes.test.ts`
- `pnpm exec vitest run
server/src/__tests__/instance-settings-routes.test.ts`
- `pnpm exec vitest run ui/src/lib/new-agent-hire-payload.test.ts
ui/src/lib/new-agent-runtime-config.test.ts`
- `pnpm -r typecheck`
- `pnpm build`
- Manual verification on a branch-local dev server:
- enabled the experimental flag
- created an SSH environment
- created a Linux Claude agent using that environment
- confirmed a run executed on the Linux box and synced workspace changes
back
## Risks
- Medium: this touches runtime execution flow across multiple adapters,
so regressions would likely show up in remote session setup, workspace
sync, or environment selection precedence.
- The UI flag reduces exposure, but the underlying runtime and route
changes are still substantial and rely on migration correctness.
- The change set is broad across adapters, control-plane services,
migrations, and UI gating, so review should pay close attention to
environment-selection precedence and remote workspace lifecycle
behavior.
## Model Used
- OpenAI Codex via Paperclip's local Codex adapter, GPT-5-class coding
model with tool use and code execution in the local repo workspace. The
local adapter does not surface a more specific public model version
string in this branch workflow.

requesting merge
Persist realized isolated/operator workspaces back onto the issue as reusable workspaces so later runs stay on the same workspace, and update the issue workspace picker to present realized isolated workspaces as existing workspaces.
