DottaandPaperclip 82884443be perf(adapter-utils): skip host scans for unchanged restores (#16312)
Skip the host snapshot scan when an unchanged workspace return matches its baseline, while retaining writer locking, both authority hooks, and changed-export conflict handling.

Verified with 270 affected tests, final-head CI/E2E, Superagent, and Apex 5/5.

Execution workspaces, services, and files — agent access

Product map: Execution workspaces, services, and files.

Review date: 2026-10-12. Source commit: 58e16dbddfc9c8d0cf60867f9d9847f0feda055b. Native REST transport reconciled in this change; see the shared transport contract.

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 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 Accepting a new pending choice advances its binding revision; superseded retries fail while current-choice retries remain idempotent.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.

Fresh standard-trust tasks with an implicit repository default can use an owned remote clone when the shared default source fails the restricted-task workspace guard. This does not grant access to the private local checkout or its Git metadata. The normal admitted Git identity must already authorize the configured remote. Creation of a fallback source is unavailable for explicit, parent/channel, reused or low-trust selections, or branch templates without a task-derived placeholder; an existing verified owned source remains reusable. Literal branch selections retain the original denial without cloning or replacing their unpublished commits. New implicit Git defaults record project-source provenance. Untyped explicit, inherited and older ambiguous checkout bindings retain the denial; admission reads the current company-scoped binding before considering the fallback. Local paths, unsupported transports and credential-bearing URLs are not fallback sources. Company/task/remote bindings, real paths, Git storage and the exact origin are revalidated for reuse, cleanup and reopening. A failed save removes only the owned task worktree. The isolated-source service and its local regression tests establish source and lifecycle boundaries; live agent/provider qualification remains separate. 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. The authoritative sandbox or SSH selection suppresses configured and built-in controller worktree and runtime provisioning regardless of task trust, source write grants or board sponsorship. Genuine isolated worktrees still permit authorized read-only source copying. Source write permission does not authorize controller execution. Explicit, channel, inherited, foreign or nondefault isolated source choices remain copy-only for controller provisioning even on local runs. Their deny-only workspace marker survives metadata and binding changes; a board reopen does not turn it into approval. Implicit trusted local defaults and explicit SSH remote provisioning retain their existing placement; no new sandbox provision transport is claimed. The implicit default follows task creation: configured policy pointer, then primary source, creation time and ID. A missing or foreign configured source does not authorize controller hooks. This precedence neither changes existing creation validation nor rotates bindings or clears retained copy-only markers. Closed-worktree reopening checks current task, agent, organizational and source policies without assuming a future driver. Effective low-trust reopens suppress configured and built-in host scripts. Returned checkpoints must have directory parents for every nested entry before merging, including unchanged entries; invalid output leaves retained host files intact and keeps recovery evidence.

Skipping the host scan for a fully unchanged returned snapshot grants no new access. The merge still holds its canonical writer lock and runs both authority and publication hooks. Denials still propagate, and checkpoint/archive validation is unchanged. Regression coverage is source-level evidence only. 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 is automated source-level evidence, not live agent qualification. Source review for these additions: PR #15749 and task workspace routes, native authority, and semantic transport.

Evidence: source-only — implementation 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 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 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: available — Authorized agent REST / native call_api / CLI runtime service controls and 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 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: No dedicated production control_workspace_service binding. Generic native calls retain runtime trust and workspace/task scope checks. 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 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 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.
