## Linked Issues or Issue Description
Refs #12215. Related changes: #11792 raised the Node requirement; #13094
addressed separate runner networking behavior. This change fixes the
engine-selection and managed-launcher paths.
**What happened?**
An unchanged agent could switch from ACP to CLI after an upgrade. Codex
CLI then used read-only permissions with networking disabled. The run
could finish without updating its task. Repeated recovery attempts used
the same unavailable setup. Managed updates also skipped the Node check
and did not refresh old launchers.
**Expected behavior**
An unavailable engine must fail with a clear setup error. It must not
silently select another engine. Explicit CLI runs must be able to write
workspace files and call the API unless the operator configures stricter
settings. Managed updates must validate Node and keep child tools on
that runtime.
**Steps to reproduce**
1. Run an ACP-default agent under Node 22 after the ACP minimum rises to
24.11.
2. Leave the engine unset and disable the approval/sandbox bypass.
3. Observe the old adapter select CLI and fail to write task disposition
through the API.
4. Start a managed service with an old launcher and a supervisor PATH
that selects a different Node for child tools.
## What Changed
- Remove automatic engine fallback for Codex, Claude, Gemini, and Kimi.
Check prerequisites for default and explicit ACP selections.
- Return a configuration error with proof that provider work did not
start. Stop automatic continuation retries for this error.
- Enable Codex ACP workspace networking at the actual turn boundary.
Upstream mode presets otherwise force it off even when config.toml
enables it. Preserve explicit network denial and read-only mode.
- Set workspace-write and network access defaults for explicit Codex CLI
runs. Preserve explicit sandbox modes, profiles, and network
restrictions.
- Pin the validated Node directory in managed launcher PATH. Refresh
legacy launchers during installs and npm/Git updates.
- Reject updates on unsupported Node. Keep update checks, dry runs, and
rollback available.
- Synchronize the qualified Codex ACP executable identity across server,
TypeScript runner, Rust runner, and provider-pack launch paths.
- Add regression tests and update engine and installation documentation.
## Verification
- [Full CI passed on the final
head](https://github.com/paperclipai/paperclip/actions/runs/34387099695):
typecheck, build/native runner verification, all general and serialized
test shards, all browser shards, release registry, canary dry run, and
policy checks.
- Greptile: 5/5 on `2c1d6e2815830a5cd39e36c8a082cc0c4441b6c0`, with no
unresolved review findings. Security gates are green.
- Full workspace typecheck and build also passed locally. The final
deployed Linux build passed.
- Full Codex, Claude, Gemini, and Kimi source test suites: 804 passed, 2
skipped. Installer, updater, and launcher tests: 47 passed. Installed
ACP turn-boundary tests: 3 passed. ACP packaging tests: 14 passed.
Focused recovery classification tests also passed.
- Real Linux Codex CLI runs, both fresh and resumed, wrote a workspace
file and reached the control-plane health API with the new defaults.
- Explicit read-only and network-disabled control probes retained those
restrictions.
- A real ACP run on the final deployed Linux build wrote a file and
reached the control-plane API with HTTP 200, without engine fallback.
The same probe failed DNS before the turn-policy patch.
- Executable-identity and installed-policy contracts: 12 passed.
Affected native server tests: 197 passed. Runner factory tests: 21
passed. Rust qualification and native provider integration tests: 11
passed.
- Deployed the production changes to a Linux service on Node 24.20 after
a verified database backup. Health, bootstrap readiness, static UI,
executable/cwd identity, and guarded restart checks passed. The restart
lost no runs.
- Corrected stale Kimi skill-default and Gemini remote-archive fixtures;
both suites pass.
## Risks
- Default or legacy auto engine settings now fail when ACP is
unavailable. Operators who intend to use CLI must select it explicitly.
- Codex CLI now permits workspace writes and networking by default, and
ACP workspace-write turns permit networking by default. Explicit
operator sandbox settings remain authoritative.
- Old managed launchers keep their pinned Node until they are
reinstalled under a supported runtime. An old updater cannot repair
itself; the documentation gives the current installer command.
- Custom service wrappers and global/source installations must configure
their runtime PATH. No database migration is required.
## Model Used
OpenAI Codex, based on GPT-6, with reasoning, repository inspection,
shell execution, and test tools. The exact serving model identifier and
context-window size are not exposed in this session.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - A Codex agent runs `codex exec`, and the adapter assembles its
argument vector from the agent's config plus execution-context options
> - For sandbox execution the adapter injects `--skip-git-repo-check`,
because a headless remote workspace has no git trust prompt to answer
> - The adapter also appends the operator's `extraArgs` verbatim, so an
agent that already lists `--skip-git-repo-check` in its config gets the
flag twice on a sandbox run
> - `codex exec` rejects a repeated `--skip-git-repo-check` and exits
with code 2, which the adapter surfaces as `adapter_failed` before any
work runs
> - This pull request skips the sandbox injection when the operator's
args already carry the flag
> - The benefit is that a common, harmless-looking config no longer
crashes every sandbox run
## Linked Issues or Issue Description
**What happened?**
A `codex_local` agent configured with `extraArgs:
["--skip-git-repo-check"]` fails on every sandbox run:
```
error: the argument '--skip-git-repo-check' cannot be used multiple times
Usage: codex exec [OPTIONS] [PROMPT]
```
The adapter reports `stopReason: "adapter_failed"` (Codex exited with
code 2). The flag appears twice in the argv: once injected by the
adapter for sandbox execution, once from the operator's `extraArgs`.
**Steps to reproduce**
1. Configure a `codex_local` agent with `extraArgs:
["--skip-git-repo-check"]` (or the legacy `args` field).
2. Point it at a sandbox environment.
3. Start a run — `codex exec` aborts immediately on the duplicate flag.
**Expected behavior**
The run launches with a single `--skip-git-repo-check`. An operator
listing the flag the adapter already injects should be a no-op, not a
hard failure.
**Paperclip version**
Current `master`.
**Deployment mode**
Any deployment running Codex agents in sandbox environments.
## What Changed
- `buildCodexExecArgs` no longer pushes the sandbox
`--skip-git-repo-check` when the resolved args (`extraArgs`, or the
legacy `args` fallback) already contain it. The operator's copy stands;
the argv carries the flag exactly once. Non-sandbox runs and configs
without the flag are unchanged.
## Verification
- `cd packages/adapters/codex-local && pnpm vitest run
src/server/codex-args.test.ts` — new cases: `extraArgs` already carrying
the flag (single occurrence), the legacy `args` field carrying it
(single occurrence), and the operator's flag preserved when the sandbox
injection is not requested. Existing "adds --skip-git-repo-check when
requested" case unchanged.
- `cd packages/adapters/codex-local && pnpm vitest run` — full package
suite (218 tests).
- `pnpm run typecheck` in the package.
## Risks
- Low. The change only suppresses a duplicate of a single, idempotent
flag; it never removes an operator-supplied argument and never adds one
that was not already going to be present.
## Model Used
Claude Fable 5 (`claude-fable-5`, Anthropic) via Claude Code — extended
thinking, agentic tool use (file edits, vitest/tsc runs). No other
models involved.

## Thinking Path
> - Paperclip is the open source control plane people use to manage AI
agents for work
> - The `codex_local` adapter runs OpenAI's Codex CLI through direct CLI
and ACP execution lanes
> - The adapter defaulted to the bare `gpt-5.6` alias while the bundled
ACP Codex version lacked GPT-5.6-family metadata
> - Default and legacy-configured runs therefore emitted
fallback-metadata warnings and could use generic context limits
> - This pull request upgrades the bundled Codex ACP dependency, selects
the concrete `gpt-5.6-sol` model, and normalizes the legacy alias in
both execution lanes
> - The benefit is correct model metadata without hiding genuine stderr
or transcript warnings
## Linked Issues or Issue Description
Related public PRs: Refs #9342, Refs #9352, and Refs #9382. This PR is
narrower: it upgrades bundled Codex metadata and normalizes the legacy
bare alias in both execution lanes.
**Bug report**
### What happened
Default `codex_local` runs, and agents still configured with the bare
`gpt-5.6` model, print a model-metadata fallback warning and use generic
context-window limits.
Root cause: the ACP lane bundled a Codex release predating
GPT-5.6-family metadata, while Paperclip's default and advertised model
used the bare `gpt-5.6` alias for which Codex publishes no metadata.
### Expected behavior
A default Codex run resolves to a concrete model slug with published
metadata and does not emit a fallback-metadata warning.
### Deployment mode
Self-hosted/local `codex_local` adapter.
## What Changed
- Upgraded `@agentclientprotocol/codex-acp` from `^1.1.0` to `^1.1.4`
- Changed `DEFAULT_CODEX_LOCAL_MODEL` from `gpt-5.6` to `gpt-5.6-sol`
- Removed the bare alias from advertised models and listed concrete
GPT-5.6 Fast-mode variants
- Added `normalizeCodexModel()` and applied it in both CLI and ACP
execution lanes
- Updated adapter docs, Storybook fixtures, and regression tests
- Preserved warning visibility; no stderr, transcript, or log filtering
changed
## Verification
- `pnpm --filter @paperclipai/adapter-codex-local typecheck`
- `pnpm check:token-gates`
- `cd packages/adapters/codex-local && pnpm exec vitest run` — 205 tests
passed
- `cd server && pnpm exec vitest run
src/__tests__/adapter-models.test.ts` — 17 tests passed
- Confirmed the PR diff excludes `pnpm-lock.yaml` and
`.github/workflows/**` as required by repository policy
- Confirmed `.github/workflows/pr.yml` regenerates and uploads the PR
lockfile artifact before downstream `pnpm install --frozen-lockfile`
steps
## Risks
Low risk. The behavior change is scoped to `codex_local` model
selection. Existing concrete model IDs pass through unchanged; only the
legacy bare `gpt-5.6` alias is rewritten. Dependency resolution may
select a newer compatible `codex-acp` release within the declared range,
so CI remains the final compatibility gate.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Each agent runs inside a sandbox environment so its CLI is isolated
from the host
> - Sandbox-backed adapter runs go through a small set of shared helpers
— `ensureAdapterExecutionTargetCommandResolvable`, the sandbox callback
bridge runner, and per-adapter `SANDBOX_INSTALL_COMMAND` strings
> - When standing up new sandbox provider plugins, the existing helpers
timed out, missed install fallbacks, or leaned on assumptions that only
held for E2B
> - Local adapters (`claude-local`, `codex-local`, `gemini-local`,
`opencode-local`) needed slightly hardened probes so they could install
themselves and validate inside *any* remote sandbox transport, not just
E2B
> - This pull request bundles those runtime fixes so future sandbox
provider plugins inherit a working baseline
> - The benefit is that adding a new sandbox provider plugin no longer
requires touching adapter-utils or each local-adapter probe — the
supporting infra is already correct
## What Changed
- `packages/adapter-utils/src/execution-target.ts`: introduce
`DEFAULT_REMOTE_SANDBOX_ADAPTER_TIMEOUT_SEC = 1800` and
`resolveAdapterExecutionTargetTimeoutSec(...)`. Local and SSH adapters
keep the historical "0 means no adapter timeout" behavior;
sandbox-backed runs without an explicit `timeoutSec` get an explicit
30-minute default so remote installs and warm-up don't time out at the
per-RPC default. Plumbed `timeoutSec` through
`ensureAdapterExecutionTargetCommandResolvable` so install probes inside
a sandbox honor adapter-level overrides instead of the bridge's 5-minute
default.
- `packages/adapters/opencode-local/src/index.ts`: switch
`SANDBOX_INSTALL_COMMAND` from `npm install -g opencode-ai` to `curl
-fsSL https://opencode.ai/install | bash`. The npm package reifies four
large prebuilt-binary subpackages in parallel even though only one
matches the host arch; on bandwidth-constrained sandboxes that blew
through the 240s install budget. The official installer fetches one
arch-specific binary and adds `$HOME/.opencode/bin` to PATH via
`~/.bashrc`, which the sandbox-callback-bridge login-shell script
already sources.
- `packages/adapters/{claude,codex,gemini,opencode}-local/`: harden
remote-target probes — pass `--skip-git-repo-check` for Codex when
probing outside a repo, normalize permission flags for Claude, and add
`*.remote.test.ts` coverage that exercises the remote-sandbox path
explicitly for each adapter.
- `packages/adapter-utils/src/sandbox-install-command.{ts,test.ts}`
(new): add `buildSandboxNpmInstallCommand` helper.
`server/src/adapters/registry.ts` + new
`server/src/__tests__/adapter-registry.test.ts`: wire adapter install
commands so they fall back to a writable `$HOME/.local` prefix when
global install isn't available.
- `server/src/__tests__/plugin-worker-manager.test.ts` + new
`server/src/__tests__/fixtures/plugin-worker-delayed.cjs`: pin per-call
timeout overrides so plugin worker exec calls honor the caller's timeout
instead of the worker's default.
## Verification
- `pnpm typecheck`
- `pnpm exec vitest run --no-coverage
packages/adapter-utils/src/execution-target-sandbox.test.ts
packages/adapter-utils/src/sandbox-install-command.test.ts`
- `pnpm exec vitest run --no-coverage
server/src/__tests__/plugin-worker-manager.test.ts
server/src/__tests__/adapter-registry.test.ts
server/src/__tests__/claude-local-adapter-environment.test.ts
server/src/__tests__/claude-local-execute.test.ts
server/src/__tests__/gemini-local-adapter-environment.test.ts`
- `pnpm exec vitest run --no-coverage
packages/adapters/codex-local/src/server/test.remote.test.ts
packages/adapters/opencode-local/src/server/test.remote.test.ts
packages/adapters/codex-local/src/server/codex-args.test.ts
packages/adapters/codex-local/src/server/execute.remote.test.ts
packages/adapters/gemini-local/src/server/execute.remote.test.ts`
All passing locally.
## Risks
- Touches shared `adapter-utils` and several `*-local` adapters. The
30-minute default applies only when both (a) the target is
`remote+sandbox` and (b) no `timeoutSec` is configured — local + SSH
paths are unchanged. New test coverage was added alongside each behavior
change to pin the contracts.
- Switching OpenCode's install command to the official installer is a
behavior change for any operator running OpenCode inside a remote
sandbox. Local installs are unaffected (the `SANDBOX_INSTALL_COMMAND`
only runs when an adapter is being installed inside a sandbox).
- Low risk overall — no migrations, no API surface change.
## Model Used
- Provider: Anthropic
- Model: Claude Opus 4.7 (1M context)
- Capabilities used: extended reasoning, tool use (Read/Edit/Bash/Grep),
no code execution beyond local repo commands

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - A fast-moving control plane needs stable local tests and repeatable
local maintenance tools so contributors can safely split and review work
> - Several route suites needed stronger isolation, Codex manual model
selection needed a faster-mode option, and local browser cleanup missed
Playwright's headless shell binary
> - Storybook static output also needed to be preserved as a generated
review artifact from the working branch
> - This pull request groups the test/local-dev maintenance pieces so
they can be reviewed separately from product runtime changes
> - The benefit is more predictable contributor verification and cleaner
local maintenance without mixing these changes into feature PRs
## What Changed
- Added stable Vitest runner support and serialized route/authz test
isolation.
- Fixed workspace runtime authz route mocks and stabilized
Claude/company-import related assertions.
- Allowed Codex fast mode for manually selected models.
- Broadened the agent browser cleanup script to detect
`chrome-headless-shell` as well as Chrome for Testing.
- Preserved generated Storybook static output from the source branch.
## Verification
- `pnpm exec vitest run
src/__tests__/workspace-runtime-routes-authz.test.ts
src/__tests__/claude-local-execute.test.ts --config vitest.config.ts`
from `server/` passed: 2 files, 19 tests.
- `pnpm exec vitest run src/server/codex-args.test.ts --config
vitest.config.ts` from `packages/adapters/codex-local/` passed: 1 file,
3 tests.
- `bash -n scripts/kill-agent-browsers.sh &&
scripts/kill-agent-browsers.sh --dry` passed; dry-run detected
`chrome-headless-shell` processes without killing them.
- `test -f ui/storybook-static/index.html && test -f
ui/storybook-static/assets/forms-editors.stories-Dry7qwx2.js` passed.
- `git diff --check public-gh/master..pap-2228-test-local-maintenance --
. ':(exclude)ui/storybook-static'` passed.
- `pnpm exec vitest run
cli/src/__tests__/company-import-export-e2e.test.ts --config
cli/vitest.config.ts` did not complete in the isolated split worktree
because `paperclipai run` exited during build prep with `TS2688: Cannot
find type definition file for 'react'`; this appears to be caused by the
worktree dependency symlink setup, not the code under test.
- Confirmed this PR does not include `pnpm-lock.yaml`.
## Risks
- Medium risk: the stable Vitest runner changes how route/authz tests
are scheduled.
- Generated `ui/storybook-static` files are large and contain minified
third-party output; `git diff --check` reports whitespace inside those
generated assets, so reviewers may choose to drop or regenerate that
artifact before merge.
- No database migrations.

## Model Used
- OpenAI Codex coding agent based on GPT-5, with shell, git, Paperclip
API, and GitHub CLI tool use in the local Paperclip workspace.
