## Thinking Path > - Paperclip manages AI agents and their work. > - Runner launches the selected provider and keeps durable session state. > - Runner currently prepares private provider homes for each session. > - Operators can already have working login, skills, and MCP configuration on the execution machine. > - This PR adds an explicit mode that uses that existing setup. > - Runner keeps its task bridge and session ownership while leaving the user's configuration in place. ## Linked Issues or Issue Description **Problem or motivation:** Rebuilding a provider home is unnecessary when the execution account is already configured. **Proposed solution:** Add `homeMode: "preconfigured"` to Runner adapter config and runnerd transport options. Keep `"isolated"` as the default. Initially support native Codex and ACPX Claude. **Alternatives considered:** Continue copying user configuration into a private home, or add an approval workflow. Both add work outside this feature's scope. **Roadmap alignment:** This extends the existing cross-provider Runner. It does not add another runtime. Related work: #14056 covers managed Codex credentials. #14474 covers command environment delivery. This mode uses user-owned credentials and retains the existing launch boundaries. ## What Changed - Add a closed v7 launch contract for the selected home mode. Existing contracts retain their behavior. - Keep homeMode under operator control. Reject task overrides and agent-authenticated changes, including removal through replacements, adapter changes, or rollback. Ignore stored task values and exclude it from automatic hire inheritance. - Skip managed AI login, assigned-skill materialization, and external MCP setup in preconfigured mode. Preserve the Runner task/completion bridge. - Keep protocol state and provider lifetime fences scoped to the Runner session. Different sessions can share a home. - Fail preconfigured ACPX planning/read-only launches before provider admission until a read-only user-home launch is qualified. Use isolated mode or native Codex for planning. - Reject ACPX approval requests. Keep native Codex on `never`. Local permission rules and hooks remain effective. Initially require the default Runner ACPX `approve-all` setting; other Runner policies are unqualified in this mode and fail before launch. - Keep the internal ACPX bridge in a stable session namespace, preserving an existing user MCP server named `paperclip`. - Reject preconfigured ACPX Codex before launch until a session permission profile can enforce Runner-state denial. Remove the unprotected full-access mode switch; use native Codex or isolated mode for that model family. - Bump Pi to profile 23 because its attestation covers shared Runner source changed here. Preserve profile 22 for historical recovery, and update Docker/package verification inputs. - Fence recovery on mode and home bindings. Fail missing provider-history recovery without starting a replacement session. Exclude the external Codex home from backups and credential cleanup. - Discover remote HOME on the execution machine. Do not project controller HOME or XDG paths onto it. - Separate task instructions from Codex ACP isolation and update the generated provider digest. - Keep remote configured-environment manifests consistent when dropping controller paths. Preserve exact Claude model IDs through per-launch environment settings, without editing the user home or patching the provider. ## Verification - Targeted local checks cover native contracts and launch allowlists, user-config preservation, provider admission, permissions, session recovery, remote environment projection, heartbeat preparation, and operator-only configuration. Runner, shared, and server TypeScript checks and the Rust binary build pass; generated ACPX profiles are current. - Following the latest master integration, all 757 server configuration/executor tests and 115 Runner admission/recovery tests passed. Additional review-fix checks passed: 103 planning contract/host tests, 78 provider-backend tests, 95 route/preparation/inheritance tests, 43 task-validator tests, and 43 workspace-policy tests. Counts describe separate runs and can overlap. - The real pinned Claude ACP/SDK regression reproduces exact-model aliasing without the fix (`claude-sonnet-5-5` becomes `sonnet`) and passes with the fix. All 89 adapter tests pass. User settings remain byte-for-byte unchanged. - Localhost-only Claude SDK probes with synthetic credentials verify the private bridge runs, local `ask` reaches the existing reject callback, local `deny` blocks without a callback, and a user MCP server named `paperclip` remains available. No user model allowlist is required. - Review regressions cover fail-closed provider admission, saved-mode recovery before routing, controller-home path removal without configured-environment manifest drift, pre-launch rejection of unqualified read-only ACPX launches, and denial of task/agent changes to the operator-owned home mode. - Before rebase, `d4d4ee2aebe4cb88c4f4d9ef8e22fed4b36b87be` received standard Greptile 5/5 with no unresolved threads. Prior Apex findings are fixed and covered by regressions. No manual Greptile retrigger is requested for this rebase, per reviewer direction. - The prior PR head and master hit the same GitHub runner encoding crash in workspace-b on three PR attempts, including diagnostic logging ([prior PR CI](https://github.com/paperclipai/paperclip/actions/runs/38818474563/job/116714538405), [prior master CI](https://github.com/paperclipai/paperclip/actions/runs/38819528748/job/116712423193)). Rebased onto `origin/master` at `c3ffa3f0dd` to pull in its bridge-test index correction. The rebased head `edd153db410bea063b645e0000aa68649f287b00` passes all CI checks ([CI run](https://github.com/paperclipai/paperclip/actions/runs/38824676914)), including workspace-b. Greptile's automatic standard review is 5/5 on this exact head, with no unresolved threads; no manual review was requested. - Local workspace-b investigation passed 911 shared tests and 3,868 tests across the remaining 15 workspace projects. The catalog run separately hit an existing ignored `.agents/skills/design-guide/SKILL.md` description-budget violation in this checkout; that file is untracked, outside the PR, and left untouched. Repeating shared tests with CI reporting enabled also passed. - Rebase verification: the final Git tree exactly matches the previously reviewed branch combined with current master. All 192 Runner admission/contract tests, 61 server preparation/provider tests, and 68 bridge tests pass, as do Runner/server TypeScript and generated-profile checks. The real Claude adapter fixture hit an `ENOTEMPTY` cleanup race on its initial run; all 89 adapter tests passed on retry. - Apex on rebased head `edd153db` returned 2/5: ACPX Codex selected full access without enforcing Runner-state denial, and agent configuration replacement could remove the operator mode. Both are fixed in `26e14dbbf`. Preconfigured ACPX Codex is temporarily unqualified; re-enabling it requires session permission enforcement on thread/turn operations and a real filesystem-denial probe. The config guard covers effective replacements, adapter changes, and rollback while allowing ordinary agent merges and operator removal. All 190 focused Runner tests, 103 server tests, both typechecks, and generated-profile checks pass. Standard review and CI passed before the next Apex request. - CI on `26e14dbbf` passed 1,967 Runner-shard tests but hit the previously observed `ENOTEMPTY` fixture cleanup race after successful Claude model admission. `eb83284fb` adds bounded filesystem retries to that fixture's teardown; all 87 adapter tests pass. Assertions and production cleanup behavior are unchanged. Head `eb83284fb42ee19a15d9a93b106c1bbb07e1695e` passes all 59 CI checks ([CI run](https://github.com/paperclipai/paperclip/actions/runs/38829500857)) and standard Greptile at 5/5 with no unresolved threads. Apex also completed at **5/5** on that exact head ([Apex result](https://github.com/paperclipai/paperclip/pull/16486#issuecomment-6201559527)). All review threads are resolved, the branch has no merge conflicts, and the PR remains unmerged. - No live paid-provider or remote-machine smoke was performed. The lockfile remains unchanged under the repository's refresh-bot policy; local dependency installation resolved the changed patch hash. ## Risks This explicit opt-in grants Codex tools access to the execution home (read-only in planning), including credentials. Native Codex separately denies Runner-owned protocol state. ACPX Claude retains its existing provider trust boundary, and the isolated default is unchanged. Providers may refresh credentials and update their own metadata. User configuration can block tools or the completion reporter. Existing blocked results and failure diagnostics remain the recovery path. Edit the local settings and retry; no new approval workflow is added. External provider history remains on the execution machine and is not backed up by Runner. Remote HOME discovery requires `getent` and fails explicitly when unavailable. Other harnesses need separate qualification. The Codex ACP bundle digest changes. Existing sessions tied to the old bundle may need a fresh session. No database migration is required. ## Model Used OpenAI Codex, GPT-6, with reasoning and code execution.
