DottaandPaperclip 9dd6526b47 fix(security): harden privileged server boundaries (#12776)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The server controls secrets, host files, outbound requests, and
workspace commands
> - A red-team review found cases where restricted callers could cross
these trust boundaries
> - These cases could expose credentials or let untrusted input reach
privileged resources
> - This pull request applies least-privilege checks at each affected
server boundary
> - The benefit is safer agent execution without changing the
private-instance bootstrap contract

## Linked Issues or Issue Description

**What happened?**

Several server paths used authorization, redaction, or content-delivery
rules that were too broad. Restricted agent keys could obtain
company-level operational data. Some adapter and instruction paths could
reach server-owned network or file resources without the required owner
approval.

**Expected behavior**

Paperclip must redact credential values, enforce restricted-key scopes,
guard outbound network access, prevent same-origin script execution, and
reserve host-level file and command controls for authorized operators.

**Steps to reproduce**

1. Configure an authenticated development instance at the parent commit.
2. Exercise the affected APIs with a restricted agent key or a
non-instance-admin company user.
3. Observe that the parent commit returns privileged data or accepts a
privileged operation.
4. Repeat on this branch and observe a redacted response, a safe
download, or an HTTP 403 response.

**Paperclip version or commit**

The findings reproduce from commit `39898ab22` and are fixed by this
pull request.

**Deployment mode**

Authenticated self-hosted server and local development modes.

**Installation method**

Built from source with pnpm.

## What Changed

- Redact generic secret `value` and `token` fields recursively in
structured logs.
- Classify exact and separator-suffixed `KEY` environment names as
secrets in company exports.
- Limit restricted self-identity responses and protect company run, log,
and secret catalog APIs.
- Route HTTP adapter requests through DNS-pinned SSRF protection with
exact private-origin allowlisting.
- Download HTML, SVG, and other script-capable assets with `nosniff` and
a sandbox CSP.
- Require instance-admin access for external instruction roots and
exports that read them.
- Block agent-authenticated host command persistence across supported
workspace runtime shapes.
- Apply the central runtime-management decision before workspace command
controls.
- Keep the documented first-user instance-admin claim contract
unchanged.
- Add regression tests and server-owner configuration documentation.

## Verification

- `pnpm -r typecheck` passes.
- The Node 24 remediation suite passes with 365 tests. It skips 25
environment-gated tests.
- `pnpm build` passes under Node 24.
- `git diff --check` passes.
- The full local runner reaches known macOS-only general-server harness
failures before the serialized route lane. The Linux PR matrix is the
authoritative full-suite gate.

## Risks

- Restricted agent keys now receive HTTP 403 responses from company-wide
run, log, and secret catalog endpoints.
- Script-capable assets now download instead of rendering inline.
- External instruction roots now require instance-admin access.
- Private HTTP adapter endpoints now require an exact origin in
`PAPERCLIP_HTTP_ADAPTER_PRIVATE_ENDPOINT_ALLOWLIST`.
- Public HTTP adapter endpoints remain enabled. Redirects and metadata
or link-local targets remain blocked.
- No database migration is required.

> 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`.

## Model Used

OpenAI Codex, GPT-5. The exact serving snapshot and context-window size
are not exposed. The model used tool-enabled reasoning, repository
access, code execution, and test execution.
