## What Changed
- Require Node.js 24.11.0 or newer in all 42 package manifests and
runtime checks.
- Use Node.js 24 in GitHub Actions, Docker images, smoke images, sandbox
setup, portable installs, and esbuild targets.
- Align every direct `@types/node` declaration on `^24.0.0`.
- Prevent Dependabot from opening major `@types/node` upgrades without a
matching runtime decision.
- Add `.nvmrc` and a CI policy check for Node version drift.
- Update ACP version gates, tests, and user documentation for the new
minimum.
- Print a non-blocking warning on CLI and server startup when Node is
unsupported, with remediation through a version manager or the
documented downloaded `install.sh` workflow.
- Deduplicate that warning when `paperclipai run` boots the CLI and
server in the same process.
## Verification
- `node scripts/check-node-version-policy.mjs`
- `node --check scripts/check-node-version-policy.mjs`
- `node --check cli/esbuild.config.mjs`
- `node --check scripts/generate-npm-package-json.mjs`
- `bash -n scripts/install.sh scripts/test-install-sh-docker.sh
scripts/e2e-install-lifecycle.sh`
- Parsed all 42 package manifests and confirmed `engines.node` is
`>=24.11.0`.
- `git diff --check`
- `vitest run
packages/adapter-utils/src/sandbox-install-command.test.ts` passed with
3 tests.
- `vitest run cli/src/node-version.test.ts` passed with 4 tests.
- Directly exercised the shared warning helper for unsupported-version
messaging and same-process deduplication.
- The focused exe.dev suite could not resolve the locally unbuilt plugin
SDK from this isolated worktree. A full offline workspace install was
also blocked because the package-manager signature verifier requires
registry access. The full suite was not run locally; draft CI performs a
clean install and evaluates the wider impact.
## Risks
- This is a breaking runtime change for users, plugins, and deployments
that still use Node.js 20 or 22.
- Published workspace packages will now produce an engine warning or
failure in strict package managers on older Node.js releases.
- Node.js 24 can reveal dependency, native module, Playwright, or agent
CLI compatibility issues in CI.
- The bootstrap installer now installs Node.js 24 when the current
runtime is older than 24.11.0.
- The portable sandbox fallback is pinned to Node.js 24.11.0 and depends
on that upstream tarball remaining available.
- Unsupported runtimes continue booting after a warning, so a later
incompatibility can still fail at its point of use.
- The CLI and server share the warning policy through the published
`@paperclipai/shared` package; packaging checks must keep that subpath
export available.
- This PR does not commit `pnpm-lock.yaml` because repository policy
assigns lockfile generation to CI.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent runs execute inside sandbox environments. Sandbox provider
plugins (Daytona, Modal, exe.dev, and others) declare a JSON-Schema
`configSchema`. The Environment configuration form renders from that
schema.
> - The sizing and image fields open empty. Users must guess working
values. The Modal form cannot submit at all until the user types an app
name and an image by hand.
> - The form renderer already pre-fills every field that declares a
JSON-Schema `default`. The manifests do not use this mechanism for
sizing or image fields.
> - This pull request adds optional `default` values to the Daytona,
Modal, and exe.dev manifest schemas.
> - The benefit is a form that opens with known-good values. Users can
create a working environment without provider research.
## Linked Issues or Issue Description
**Current behavior**
The Environment configuration form opens with empty sizing and image
fields for the Daytona, Modal, and exe.dev sandbox providers. Users must
find working values in provider documentation. Modal declares `appName`
and `image` as required with no default, so the form blocks submission
until the user invents both values.
**Proposed behavior**
The provider manifests declare JSON-Schema `default` values. The
existing form renderer pre-fills them:
- Daytona: CPU `4`, memory `4` GiB, disk `10` GiB, image
`daytonaio/sandbox:0.8.0`
- exe.dev: CPU `4`, memory `4GB`, disk `20GB`
- Modal: app name `paperclip`, image `node:22`
Secret-ref fields (API keys, tokens) get no defaults on purpose. The
form persists a raw string in a secret-ref field as a company secret on
save. A placeholder default would become a stored secret with a bogus
value. Each plugin test suite now guards this invariant.
**Reason and benefit**
New users can create a working sandbox environment without guessing. The
defaults stay optional: users can clear or change every value, and the
schema marks no new field as required. The Modal image default `node:22`
satisfies the sandbox runtime contract in `SANDBOX-REQUIREMENTS.md`
(`node`, `sh`, and `tar` on PATH).
**Subsystem affected**
Sandbox provider plugins (`packages/plugins/sandbox-providers/*`):
environment driver `configSchema` manifests.
**Breaking changes**
None. Defaults only seed the create-mode form. Saved environments keep
their stored config. E2B, Novita, Cloudflare, and Kubernetes manifests
do not change: E2B and Novita already default to their base templates,
and the Cloudflare bridge and Kubernetes cluster fields have no sensible
universal value.
## What Changed
- Add `default` values for `cpu`, `memory`, `disk`, and `image` in the
Daytona manifest. Trim the memory description to match.
- Add `default` values for `cpu`, `memory`, and `disk` in the exe.dev
manifest.
- Add `default` values for `appName` and `image` in the Modal manifest.
Extend the image description with the runtime-contract rationale.
- Add manifest tests in all three plugins: defaults match expected
values, defaults satisfy their own schema constraints, and no secret-ref
field declares a default.
- Bump plugin versions: daytona and modal `0.1.0` → `0.1.1`, exe-dev
`0.1.1` → `0.1.2`.
## Verification
- Run `pnpm test` in `packages/plugins/sandbox-providers/daytona`,
`.../modal`, and `.../exe-dev`. The new `* manifest form defaults`
suites pass.
- Run `./node_modules/.bin/tsc --noEmit` in each of the three packages.
Typecheck passes.
- Manual: rebuild the plugins (`pnpm build` in each package), let the
plugin dev-watcher refresh the manifest, then open Environments → New
environment. The Daytona form shows CPU 4, Memory 4, Disk 10, and image
`daytonaio/sandbox:0.8.0`. The Modal form shows `paperclip` and
`node:22`. The API key fields stay empty.
- Verified live on a local instance: the served `configSchema` in the
plugin registry carries the new defaults, and existing environments are
unchanged.
## Risks
- Low risk. The change touches only manifest schema metadata and tests.
No runtime code path changes.
- New environments created with untouched forms now request 4 CPU / 4
GiB / 10 GiB from Daytona instead of provider minimums. This can raise
cost per sandbox for users who previously saved empty fields.
- The Daytona image default pins `daytonaio/sandbox:0.8.0`. The default
needs a manual bump when Daytona ships new sandbox images.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox-provider plugins (cloudflare, daytona, e2b, exe-dev,
kubernetes, modal, novita) and `plugin-workspace-diff` are published as
standalone npm packages, but during local dev they need the in-repo
`@paperclipai/plugin-sdk` symlinked in
> - Each of these plugins shipped a `postinstall` lifecycle script that
traversed *out* of its own package directory (`node
../../../../scripts/link-plugin-dev-sdk.mjs`) to do that linking
> - The publishable manifest is built by a `prepack` whitelist that
drops the `scripts` field, so npm consumers don't see the postinstall
today — but that safety property depends entirely on `prepack` running
on every publish. A publish that skips lifecycle scripts would ship a
tarball whose postinstall escapes its package directory at consumer
install time
> - This pull request removes the escape-the-package-dir lifecycle
script from every plugin source manifest and moves the dev linking to a
single root-level postinstall that iterates the excluded plugin
directories itself
> - The benefit is that plugin tarballs can no longer carry an
install-time script that reaches outside their own directory, regardless
of whether `prepack` runs
## Linked Issues or Issue Description
This is a follow-up hardening change flagged during review of the Novita
sandbox provider PR (#7595).
**Problem (security):** Excluded plugin packages each carried
`"postinstall": "node ../../../../scripts/link-plugin-dev-sdk.mjs"`. The
relative path traverses outside the package root. Today the published
manifest is sanitized by a `prepack` whitelist that drops `scripts`, so
consumers are unaffected in the normal publish path. The risk is that
this is a defense-in-depth gap: if a publish ever skips lifecycle
scripts (e.g. `npm publish --ignore-scripts` is *not* used, or a tool
publishes the raw manifest), the tarball would ship a postinstall that
runs out-of-tree code at the consumer's install time.
## What Changed
- Added a single root `package.json` `postinstall`: `node
scripts/link-plugin-dev-sdk.mjs`.
- Rewrote `scripts/link-plugin-dev-sdk.mjs` to iterate the excluded
plugin directories itself (`packages/plugins/sandbox-providers/*` + the
orchestration smoke example) instead of relying on each plugin to invoke
it from its own cwd. Preserves both prior behaviors: leave a real
installed SDK dir alone, and skip when already correctly symlinked
(idempotent).
- Removed `scripts.postinstall` from all 7 sandbox-provider plugins
(cloudflare, daytona, e2b, exe-dev, kubernetes, modal, novita).
- Removed `scripts.postinstall` from `plugin-workspace-diff` (a pnpm
workspace member — pnpm already links the SDK, so the script was a no-op
there).
## Verification
- `node scripts/link-plugin-dev-sdk.mjs` from repo root: links the SDK
into the excluded plugins and reports skipped (already-linked) dirs;
re-running is idempotent.
- `grep -r "link-plugin-dev-sdk" packages/plugins/*/package.json
packages/plugins/sandbox-providers/*/package.json` returns no matches —
no plugin source manifest references the linker any longer.
- All affected `package.json` files re-validated as parseable JSON.
## Risks
Low risk. Dev-only tooling: the linker only runs at the repo root during
local install and only touches `node_modules/@paperclipai/plugin-sdk`
symlinks inside excluded plugin dirs. No change to published plugin
behavior or runtime code. Worst case if the root postinstall failed to
run, local dev of an excluded plugin would not find the SDK symlink —
easily re-run manually.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Test infrastructure across server, ui, packages/* runs on Vitest
> - Dependabot opened a narrow bump (3.2.4 → 3.2.6), but the wider
workspace is on 3.2.4 and the major-version bridge to v4 needs a
coordinated change set across configs and tests
> - Staying on 3.x indefinitely leaves us behind on Vitest 4 (perf,
pool, and config improvements) and forces repeated patch-only dependabot
churn
> - This pull request upgrades Vitest to 4.1.8 across the workspace,
updates `server/vitest.config.ts` and `scripts/run-vitest-stable.mjs`
for the new API, and adjusts two UI tests for the new assertion
semantics
> - The benefit is a single, coherent Vitest 4 upgrade that supersedes
#7570 and gets us on the supported major line
## What Changed
- Bump `vitest` from `3.2.4` to `4.1.8` across root, `server`, `ui`, and
all `packages/*` (including plugin examples and sandbox providers)
- Update `server/vitest.config.ts` for Vitest 4 config surface
- Update `scripts/run-vitest-stable.mjs` to match the new runner
behavior
- Adjust `ui/src/components/CommentThread.test.tsx` and
`ui/src/components/MarkdownEditor.test.tsx` for Vitest 4 matcher/timing
semantics
- Refresh `pnpm-lock.yaml`
## Verification
- `pnpm install` resolves cleanly with the new lockfile
- `pnpm -w -r test` (server, ui, packages) runs under Vitest 4.1.8
## Risks
- Major-version Vitest bump: behavioral changes in pools, fake timers,
and matcher strictness can surface flake. Test config and the two UI
tests were updated to match v4 semantics; broader test runs should be
watched on CI before merge.
- Supersedes dependabot PR #7570 (3.2.4 → 3.2.6); that PR should be
closed.

Closes#7570
## Thinking Path
> - Paperclip orchestrates AI agents and provisions sandboxed execution
environments for them; one of those provisioners is the exe.dev plugin,
which runs each agent inside a long-lived VM reached over SSH.
> - The instance-config form for that plugin is rendered generically by
`JsonSchemaForm` from the plugin's `instanceConfigSchema`, so any UX
problem with the form is split between the shared form component and the
plugin's schema/runtime code.
> - Users coming in cold hit a 12-field flat config they couldn't reason
about (PAPA-407), a form that silently submitted `cpu: 0` for untouched
optional fields (PAPA-407 root cause), a `sshPrivateKey` textarea that
truncated RSA-4096 keys at 4096 chars (PAPA-449), a save flow that
accepted clearly-malformed keys and only blew up at lease time with raw
SSH stderr (PAPA-450, PAPA-451), and a manifest that didn't distinguish
"essential" from "advanced" knobs (PAPA-410 / PAPA-411 — duplicate
sub-issues with identical scope; PAPA-418 reconciliation kept PAPA-410
canonical).
> - These problems all point at the same surface (exe.dev sandbox
config) and are tightly coupled in code — PAPA-449/450/451 patch fields
that PAPA-410/411 introduce — so they get reviewed together.
> - This pull request lands the shared-form changes (advanced-options
disclosure, optional-scalar defaults) and the exe.dev-specific changes
(manifest restructure, longer `maxLength`, stderr translation, save-time
key validation) as five focused commits stacked on `master`.
> - The benefit is a config form that defaults to the two fields a new
user actually needs (API key + SSH private key) with a collapsible
disclosure for the rest, no silent truncation or zero-default
submissions, and SSH key problems surfaced at save time with actionable
messages instead of cryptic post-provision failures.
## What Changed
- **JsonSchemaForm advanced-options disclosure** (PAPA-410, PAPA-411 —
same scope, see note above): adds `x-paperclip-advanced` /
`x-paperclip-group` schema annotations and renders flagged fields behind
a collapsible "Advanced options" disclosure that auto-opens when a
hidden field has a validation error. Exe.dev manifest is restructured to
use the new annotations, so essentials (`apiKey`, `sshPrivateKey`) show
by default while the long tail of optional knobs is grouped under "SSH
access" / "VM resources" / "More options" headings.
- **Omit optional scalar defaults** (PAPA-407): `getDefaultForSchema` no
longer materialises `0` / `""` for optional
`number`/`integer`/`string`/`secret-ref` fields without an explicit
`default`. Object recursion drops properties whose default is
`undefined`. Fields that declare a `default` (e.g. `sshPort: 22`) still
round-trip. Adds a regression test against `getDefaultValues`.
- **Raise `sshPrivateKey` `maxLength`** (PAPA-449): bumps the exe.dev
manifest cap from 4096 to 8192 so RSA-4096 OpenSSH private keys (which
can exceed 4 KB with comments/metadata) aren't silently truncated at
submit.
- **Translate `invalid format` SSH stderr** (PAPA-450):
`formatSshFailure` now recognises `Load key … invalid format` in
combined stderr/stdout and returns a specific message naming the
key-format problem ("isn't an OpenSSH/PEM private key — confirm the
secret starts with `-----BEGIN … PRIVATE KEY-----` and isn't the `.pub`
or a PuTTY `.ppk` export") instead of dumping the raw stderr.
- **Save-time SSH key validation** (PAPA-451):
`onEnvironmentValidateConfig` inline-parses `sshPrivateKey` and rejects
common failure modes — pasted public keys, PuTTY `.ppk` format, missing
`-----END-----` footer, non-base64 body — so the form surfaces an inline
error before any VM is provisioned. Secret-ref bindings (UUIDs) are
still passed through unchanged.
## Verification
CI gates (`pnpm typecheck`, `pnpm test`, the targeted vitest suites
below) all pass.
Run locally:
```bash
# Shared form
pnpm --filter @paperclipai/ui exec vitest run src/components/JsonSchemaForm
# 9 tests pass — includes the new "omits optional scalar fields" regression
# and the three advanced-options-disclosure tests.
# exe.dev plugin
cd packages/plugins/sandbox-providers/exe-dev && pnpm test
# 32 tests pass — includes the new sshPrivateKey-validation cases
# and the new "invalid format" stderr-translation case.
```
Manual smoke (after reinstalling the plugin so the DB manifest
refreshes):
1. Open the exe.dev environment config page. **Default view shows API
Key + SSH Private Key only**, with an "Advanced options" disclosure for
everything else (PAPA-410 / PAPA-411).
2. Paste a `.pub` file's contents into SSH Private Key, click Save.
**Inline error** rejecting the wrong-format key (PAPA-451).
3. Re-paste a valid OpenSSH/PEM private key longer than 4096 bytes —
saves cleanly (PAPA-449).
4. Save the form with everything optional left blank — server no longer
rejects with `"cpu must be greater than 0 when provided"` (PAPA-407).
5. Force a bad key through via a stored secret-ref binding and lease a
VM — failure message names the key-format problem instead of dumping raw
SSH stderr (PAPA-450).
## Risks
- **PAPA-410 / PAPA-411 manifest restructure** is the largest surface
here. Schemas using `x-paperclip-*` extensions are forward-compatible
with stricter JSON Schema validators (extensions are ignored by
default), and the form gracefully renders a flat layout when no field
opts in.
- **PAPA-407** changes form-default behaviour: optional scalar fields
that previously round-tripped as `""` / `0` will now be `undefined` and
absent from the submitted payload. Downstream consumers that expected
the empty-string/zero shape need to treat the field as optional.
Spot-checked the existing exe.dev driver — it already uses
`parseOptionalString` / `parseOptionalInteger`, which treat missing
fields as `null` rather than `0`/`""`.
- **PAPA-451** adds a save-time check, so a
previously-saved-but-malformed `sshPrivateKey` raw value will now fail
to re-save. Bound secret-refs are unaffected, matching how the user
reaches the bad-key state today (via the secrets picker).
- **PAPA-449** simply raises a cap; no semantic risk.
- **PAPA-450** only kicks in on the "invalid format" code path; existing
onboarding-marker branch is untouched.

> _Stacked on top of #5685 → #5686 → #5687. Diff against master includes
commits from earlier PRs in the stack — review focuses on the two new
commits (`Add long-secret textarea variant to JsonSchemaForm
SecretField` + `Add exe.dev sandbox provider plugin`)._
## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Each agent runs in a sandbox environment, and operators choose the
provider — today E2B, Daytona, and (in this stack) Cloudflare
> - exe.dev offers per-VM sandboxes via a small CLI / HTTP API — useful
for operators who want full Linux VMs (vs container/runtime-only
sandboxes)
> - The plugin shape mirrors the e2b plugin: lifecycle hooks (`new`,
`ls`, `rm`) drive exe.dev's CLI; SSH plumbing handles direct VM access
for adapters that need it
> - exe.dev VMs come up bare — `node` is not preinstalled, so the
Paperclip sandbox callback bridge (a Node script) needs Node 20
installed at VM init via `--setup-script`. The plugin defaults the setup
script to a Nodesource install
> - The auth field accepts long SSH private keys, which need a textarea
variant of the existing `SecretField` in `JsonSchemaForm` — added behind
a `maxLength > THRESHOLD` opt-in so other secret fields are unaffected
> - The benefit is that operators get exe.dev as a fully working sandbox
provider out of the box, with no manual VM provisioning required
## What Changed
**Shared UI support (`Add long-secret textarea variant to JsonSchemaForm
SecretField`):**
- `ui/src/components/JsonSchemaForm.tsx` + new
`JsonSchemaForm.test.tsx`: when a secret-formatted field declares
`maxLength` larger than the existing single-line threshold, render a
monospace textarea instead of the masked input. Short secrets (API keys,
tokens) keep the existing masked-input + show/hide toggle behavior.
**The exe.dev plugin (`Add exe.dev sandbox provider plugin`):**
- `packages/plugins/sandbox-providers/exe-dev/`: plugin entry, manifest,
plugin runtime, README, and 19-test Vitest suite.
- Manifest fields: API token (with `secret-ref` + `/exec` permission
notes — needs `new`, `ls`, `rm`), API URL override, optional SSH
username, optional SSH private key (uses the new `JsonSchemaForm`
textarea variant via `maxLength: 4096`), optional SSH identity-file
path, optional setup script.
- Default `--setup-script` is a Nodesource Node 20 install. exe.dev VMs
come up bare and the Paperclip sandbox callback bridge is a Node script,
so without Node preinstalled the bridge can't start. Operators can
override by supplying their own setup script.
- `runLifecycleCommand` redacts env values from the executed command
before surfacing it in error messages, so secrets passed via
`--env=KEY=VALUE` don't leak into operator-visible failures.
- The plugin distinguishes exe.dev's SSH onboarding failures (`Please
complete registration by running: ssh exe.dev`) from general SSH
failures and surfaces a clear remediation message.
- `scripts/release-package-manifest.json`: register the new plugin for
CI publish alongside the existing daytona / e2b providers.
## Verification

- `pnpm exec vitest run --no-coverage

- `(cd packages/plugins/sandbox-providers/exe-dev && pnpm test)` — 19
passing
For an operator-side smoke test:
1. Get an exe.dev API token with `/exec` permission for `new`, `ls`,
`rm`.
2. Register the plugin in your Paperclip instance, configure an
environment with the token.
3. Create a sandbox env whose provider is `exe-dev`, then run a Codex or
Claude job against it. The default Node 20 setup script should bring the
VM up automatically.
## Risks
- Adds a new sandbox provider plugin that follows the existing daytona /
e2b shape; behavior on existing providers is unchanged.
- The `JsonSchemaForm` textarea variant only engages for fields that opt
in via `maxLength` larger than the existing threshold. All existing
secret fields (which don't declare a `maxLength`) keep their current
rendering. Test coverage pins both paths.
- The redaction in `runLifecycleCommand` is a defense-in-depth measure;
the test suite exercises the redaction path. If the redaction misses a
future env-arg shape, the worst case is restored behavior (secrets in
error messages), which is what the existing daytona / e2b plugins also
do today.
- Default setup script downloads from `deb.nodesource.com` over HTTPS at
VM init. Operators on air-gapped networks or with a different package
strategy can override the setup script.
