## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Sandbox environments are part of that execution layer, and the
recent core refactor moved provider-specific behavior to a generic
plugin seam
> - This pull request adds a dedicated `@paperclipai/plugin-e2b` package
so E2B can live entirely outside core host code
> - Because the feature is still unreleased, the plugin should model
third-party packaging directly instead of carrying extra
backward-compatibility complexity in core or the workspace lockfile
> - This branch therefore makes the E2B provider a standalone
publishable package, documents the package-local dev flow, and keeps the
publish manifest/runtime dependency story correct
> - The benefit is that E2B becomes a true plugin reference
implementation that can be installed by package name without reopening
core Paperclip code
## What Changed
- Added `packages/plugins/paperclip-plugin-e2b` as the E2B sandbox
provider plugin package
- Implemented config validation, lease acquire/resume/release/destroy
handlers, workspace realization, and command execution for E2B sandboxes
- Excluded the E2B plugin package from the root workspace so the repo no
longer needs `pnpm-lock.yaml` churn for its third-party dependency graph
- Added package-local development/install support plus a prepack
manifest generator so the published tarball still declares
`@paperclipai/plugin-sdk` and `e2b` runtime dependencies
- Addressed review feedback by fixing sandbox cleanup on acquire
failures, rejecting blank templates, normalizing fractional `timeoutMs`,
and always passing the configured template name to the E2B SDK
- Updated focused Vitest coverage for config normalization, validation,
acquire cleanup, command execution, and lease release behavior
- Updated the Dockerfile deps stage to copy the E2B package manifest so
the policy check stays in sync
## Verification
- `cd packages/plugins/paperclip-plugin-e2b && pnpm install
--ignore-workspace --no-lockfile`
- `cd packages/plugins/paperclip-plugin-e2b && pnpm build`
- `cd packages/plugins/paperclip-plugin-e2b && pnpm --ignore-workspace
test`
- `cd packages/plugins/paperclip-plugin-e2b && pnpm --ignore-workspace
typecheck`
- `cd packages/plugins/paperclip-plugin-e2b && npm pack --dry-run`
## Risks
- The package now relies on a prepack manifest rewrite so the
publish-time dependency list stays correct while the repo-local dev
manifest stays workspace-light
- The current repo snapshot is still unreleased, so the generated
publish manifest points at the repo SDK version until the normal release
flow rewrites versions before publish
- Real-world E2B environments may still expose edge cases around
lifecycle timing or sandbox metadata beyond the mocked unit coverage
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

* ci: add Dockerfile deps stage validation to PR policy
Checks that all workspace package.json files and the patches/
directory are copied into the Dockerfile deps stage. Prevents the
Docker build from breaking when new packages or patches are added
without updating the Dockerfile.

* ci: scope Dockerfile check to deps stage and derive workspace roots
Address Greptile review feedback:
- Use awk to extract only the deps stage before grepping, preventing
false positives from COPY lines in other stages
- Derive workspace search roots from pnpm-workspace.yaml instead of
hardcoding them, so new top-level workspaces are automatically covered
* ci: guard against empty workspace roots in Dockerfile check
Fail early if pnpm-workspace.yaml parsing yields no search roots,
preventing a silent false-pass from find defaulting to cwd.
* ci: guard against empty deps stage extraction
Fail early with a clear error if awk cannot find the deps stage in the
Dockerfile, instead of producing misleading "missing COPY" errors.
* ci: deduplicate find results from overlapping workspace roots
Use sort -u instead of sort to prevent duplicate error messages when
nested workspace globs (e.g. packages/* and packages/adapters/*) cause
the same package.json to be found twice.
* ci: anchor grep to ^COPY to ignore commented-out Dockerfile lines
Prevents false negatives when a COPY directive is commented out
(e.g. # COPY packages/foo/package.json).

Merge pr-verify.yml, pr-policy.yml, and pr-e2e.yml into a single
pr.yml with three parallel jobs (policy, verify, e2e). Benefits:
- Single concurrency group cancels all jobs on new push
- Consistent Node 24 across all jobs
- One file to maintain instead of three
The jobs still run independently (no artifact sharing) since pnpm
cache makes install fast and the upload/download overhead for
node_modules would negate the savings.
