# Execution workspaces, services, and files — agent access

Product map: [Execution workspaces, services, and files](../feature-map/workspaces.md).

Review date: 2026-10-12. Source commit: `f981fa3cc10cb8663a87dec60345fbff46d54d0a`.

This is a source-reviewed baseline of representative operations and known gaps.
Each capability needs operation-level review before its entire scope can be
qualified. No live agent execution is claimed. Follow the [map contract](../README.md)
for format, permission checks, evidence and maintenance.

## `binding`

Review: `baseline`.

API: `present` — representative operation IDs:

- `GET /api/issues/{id}/heartbeat-context`.
- `GET /api/execution-workspaces/{id}`.
- `GET /api/issues/{id}/workspace` inspects the durable task binding.
- `PUT /api/issues/{id}/workspace` requests the next binding.
- `GET /api/companies/{companyId}/execution-workspaces?summary=true&selectableForTask=true`
  lists authorized task-selectable workspaces.

Agent access: `available` — Native get_task_context / REST / CLI / MCP workspace read.

The task-bound native tools `get_workspace`, `list_workspaces`, and
`select_workspace` use the ordinary authenticated APIs. Legacy agents can call
those APIs with their admitted run token. These paths do not require a project.

Policy: Company/project/workspace visibility and runtime authority; active run, trust
preset and task ownership where required.

Task workspace writes require `issue:mutate`, an active owned task/run for agents,
and current source visibility. Shared physical roots also require source-project
workspace write authority. Accepting a new pending choice advances its binding
revision; superseded retries fail while current-choice retries remain idempotent.
Binding revisions and request keys fence retries;
selection applies at the next normal admission without interrupting a live run.
Writable aliases must also be compatible with current and retained physical
source projects' trust boundaries. Incompatible choices are rejected before
dispatch; a projectless alias cannot bypass required sandbox containment.
Source-copy checks apply the same trust boundary before provisioning. Low-trust
sandbox runs skip host worktree provisioning, including built-in scripts.
Child creation by an admitted agent checks an explicit prospective-task context before the child is saved. The creator run must have an authoritative saved policy and a verified company/agent/parent lineage. Current parent, prospective child and physical source policies must fit that boundary. This creation path does not relax exact task/run checks for existing-task writes. The [child trust regression](../../server/src/__tests__/task-workspace-child-trust.test.ts) is automated source-level evidence, not live agent qualification.
Source review for these additions: PR #15749 and
[task workspace routes](../../server/src/routes/task-workspaces.ts),
[native authority](../../server/src/services/native-runtime/paperclip-runner-tool-authority.ts),
and [semantic transport](../../server/src/services/task-workspace-tools.ts).

Evidence: `source-only` —
[implementation](../../server/src/routes/workspace-runtime-service-authz.ts#L76) at the
reviewed commit above.

Verification: `not-run` — exercise a listed permitted operation with actual agent
credentials/run context; inspect its result and applicable persistence/attribution.
Assert the relevant denied actor, owner, company or mode from Policy. Review the
remaining operations before qualifying the whole capability.

Gaps: Run/task context identifies its actual realized workspace; record existence is not
a running service.

## `provisioning`

Review: `baseline`.

API: `present` — representative operation IDs:

- `GET /api/execution-workspaces/{id}`.
- `GET /api/execution-workspaces/{id}/workspace-operations`.
- `POST /api/issues/{id}/workspace/repositories` requests repository preparation.

Agent access: `partial` — REST / native call_api reads; task/project assignment triggers
server provisioning.

Native `prepare_repository` and admitted legacy REST callers can request a
catalog repository or validated repository URL for their current task.
Preparation occurs at normal admission; the agent cannot supply a host path or
controller identity. Current source permissions, responsible-user intersection,
trust restrictions, immutable receipts, and retained physical-root ownership are
checked before acquisition and publication. Low-trust callers cannot trigger a
new controller-side Git acquisition. Evidence remains source-only here; focused
[repository tests](../../server/src/__tests__/task-workspace-repositories-trust.test.ts)
are separate from live agent qualification.

Policy: Company/project/workspace visibility and runtime authority; active run, trust
preset and task ownership where required.

Evidence: `source-only` —
[implementation](../../server/src/routes/workspace-runtime-service-authz.ts#L76) at the
reviewed commit above.

Verification: `not-run` — exercise a listed permitted operation with actual agent
credentials/run context; inspect its result and applicable persistence/attribution.
Assert the relevant denied actor, owner, company or mode from Policy. Review the
remaining operations before qualifying the whole capability.

Gaps: Observing readiness exists. Creating host commands or arbitrary provision targets
is a separate protected operation.

## `services`

Review: `baseline`.

API: `present` — representative operation IDs:

- `POST /api/execution-workspaces/{id}/runtime-services/{action}`.

Agent access: `partial` — Authorized agent REST / CLI workspace runtime-service /
existing stdio MCP controls.

Policy: Company/project/workspace visibility and runtime authority; active run, trust
preset and task ownership where required.

Evidence: `source-only` —
[implementation](../../server/src/routes/workspace-runtime-service-authz.ts#L76) at the
reviewed commit above.

Verification: `not-run` — exercise a listed permitted operation with actual agent
credentials/run context; inspect its result and applicable persistence/attribution.
Assert the relevant denied actor, owner, company or mode from Policy. Review the
remaining operations before qualifying the whole capability.

Gaps: Native call_api blocks runtime-service mutation; control_workspace_service is not
in the production authority set. Optional MCP availability must be recorded.

## `files-git`

Review: `baseline`.

API: `present` — representative operation IDs:

- `GET /api/issues/{issueId}/file-resources/content`.
- `GET /api/issues/{issueId}/file-resources/list`.

Agent access: `partial` — Authorized workspace filesystem tools; Dot workspace bridge
when enabled; board file-resource HTTP UI.

Policy: Company/project/workspace visibility and runtime authority; active run, trust
preset and task ownership where required.

Evidence: `source-only` —
[implementation](../../server/src/routes/workspace-runtime-service-authz.ts#L76) at the
reviewed commit above.

Verification: `not-run` — exercise a listed permitted operation with actual agent
credentials/run context; inspect its result and applicable persistence/attribution.
Assert the relevant denied actor, owner, company or mode from Policy. Review the
remaining operations before qualifying the whole capability.

Gaps: Files panel HTTP requires board. Agents can use their admitted workspace file
tools; remote/Dot scope and Git command availability differ.

File reads also enforce retained source privacy after local copy, configuration
move/removal, reopen, and project deletion. A task assignment or repository
receipt does not grant access to private files from another physical owner.

Authorized Git-source capture also retains ownership on the actual shared Git
storage. Source checks use verified checkout identities, including company-known
owners when separate metadata has no primary-checkout registration. Removing that
checkout does not release its private committed files in surviving worktrees.

## `closure`

Review: `baseline`.

API: `present` — representative operation IDs:

- `PATCH /api/execution-workspaces/{id}`.
- `GET /api/execution-workspaces/{id}/close-readiness`.
- `POST /api/execution-workspaces/{id}/reconcile-branch`.

Agent access: `partial` — REST / native fallback for permitted update; CLI workspace;
reconcile-branch requires board.

Policy: Company/project/workspace visibility and runtime authority; active run, trust
preset and task ownership where required.

Evidence: `source-only` —
[implementation](../../server/src/routes/workspace-runtime-service-authz.ts#L76) at the
reviewed commit above.

Verification: `not-run` — exercise a listed permitted operation with actual agent
credentials/run context; inspect its result and applicable persistence/attribution.
Assert the relevant denied actor, owner, company or mode from Policy. Review the
remaining operations before qualifying the whole capability.

Gaps: Closure/readiness exists; not every workspace can be reopened, and branch
reconciliation has a board boundary.
