## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox providers let agents run in remote environments
> - The Daytona login flow creates a home directory for each login
session
> - The create path ran owner, mode, and link-type checks inside the
sandbox
> - These checks cannot protect the host because sandbox code can change
the checked state
> - This pull request uses one `mkdir -p` command and removes the unused
helper scripts
> - The benefit is a simpler login path with the host-side credential
checks unchanged
## Linked Issues or Issue Description
**What happened?**
The Daytona login flow used helper scripts and inside-sandbox checks for
the session-home directory. The standalone package build also copied a
scripts directory that no longer existed after the helper scripts were
removed.
**Expected behavior**
The login flow must create the session home with one `mkdir -p` command.
The package build must complete without copying a removed directory.
**Steps to reproduce**
1. Build the Daytona plugin package.
2. Start a Daytona device login.
3. Inspect the session-home create command and the package output.
**Paperclip version or commit**
Commit `dfdf5914ba37caa1e3bc380236844a7d76237e12`.
**Deployment mode**
Built from source.
## What Changed
- Replace the session-home helper checks with one `mkdir -p` command.
- Remove the two unused session-home helper scripts.
- Remove the dead build copy steps for the deleted scripts directory.
- Add coverage for a failed session-home create command.
- Keep the host-side credential reader unchanged.
- Keep the Kubernetes provider package unchanged.
## Verification
- Package unit tests pass: 220 passed, 6 skipped.
- Package typecheck passes.
- The package build passes and emits 56 files in `dist`.
- The roadmap check confirms that this change stays within the planned
sandbox-provider work.
- GitHub search found no open duplicate or related pull request.
## Risks
The login flow no longer reports owner, mode, or link-type errors from
inside the sandbox. Those checks did not protect the host. The host-side
credential reader still uses no-follow path opens and accepts only a
regular file with owner and exact mode `0600`. Risk is low because this
change removes checks that cannot enforce the host security boundary.
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. This pull request updates an
existing sandbox-provider path, not a new core feature.
## Model Used
OpenAI Codex, GPT-5. The runtime provides tool use and code execution.
The runtime does not expose the context window size or a more specific
model identifier.
