## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies.
> - The environment/runtime layer decides where agent work executes and
how the control plane reaches those runtimes.
> - Today Paperclip can run locally and over SSH, but sandboxed
execution needs a first-class environment model instead of one-off
adapter behavior.
> - We also want sandbox providers to be pluggable so the core does not
hardcode every provider implementation.
> - This branch adds the Sandbox environment path, the provider
contract, and a deterministic fake provider plugin.
> - That required synchronized changes across shared contracts, plugin
SDK surfaces, server runtime orchestration, and the UI
environment/workspace flows.
> - The result is that sandbox execution becomes a core control-plane
capability while keeping provider implementations extensible and
testable.
## What Changed
- Added sandbox runtime support to the environment execution path,
including runtime URL discovery, sandbox execution targeting,
orchestration, and heartbeat integration.
- Added plugin-provider support for sandbox environments so providers
can be supplied via plugins instead of hardcoded server logic.
- Added the fake sandbox provider plugin with deterministic behavior
suitable for local and automated testing.
- Updated shared types, validators, plugin protocol definitions, and SDK
helpers to carry sandbox provider and workspace-runtime contracts across
package boundaries.
- Updated server routes and services so companies can create sandbox
environments, select them for work, and execute work through the sandbox
runtime path.
- Updated the UI environment and workspace surfaces to expose sandbox
environment configuration and selection.
- Added test coverage for sandbox runtime behavior, provider seams,
environment route guards, orchestration, and the fake provider plugin.
## Verification
- Ran locally before the final fixture-only scrub:
- `pnpm -r typecheck`
- `pnpm test:run`
- `pnpm build`
- Ran locally after the final scrub amend:
- `pnpm vitest run server/src/__tests__/runtime-api.test.ts`
- Reviewer spot checks:
- create a sandbox environment backed by the fake provider plugin
- run work through that environment
- confirm sandbox provider execution does not inherit host secrets
implicitly
## Risks
- This touches shared contracts, plugin SDK plumbing, server runtime
orchestration, and UI environment/workspace flows, so regressions would
likely show up as cross-layer mismatches rather than isolated type
errors.
- Runtime URL discovery and sandbox callback selection are sensitive to
host/bind configuration; if that logic is wrong, sandbox-backed
callbacks may fail even when execution succeeds.
- The fake provider plugin is intentionally deterministic and
test-oriented; future providers may expose capability gaps that this
branch does not yet cover.
## Model Used
- OpenAI Codex coding agent on a GPT-5-class backend in the
Paperclip/Codex harness. Exact backend model ID is not exposed
in-session. Tool-assisted workflow with shell execution, file editing,
git history inspection, and local test execution.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Hiring agents is a governance-sensitive workflow because it grants
roles, adapter config, skills, and execution capability
> - The create-agent skill needs explicit templates and review guidance
so hires are auditable and not over-permissioned
> - Skill sync also needs to recognize bundled Paperclip skills
consistently for Codex local agents
> - This pull request expands create-agent role templates, adds a
security-engineer template, and documents capability/secret-handling
review requirements
> - The benefit is safer, more repeatable agent creation with clearer
approval payloads and less permission sprawl
## What Changed
- Expanded `paperclip-create-agent` guidance for template selection,
adjacent-template drafting, and role-specific review bars.
- Added a Security Engineer agent template and collaboration/safety
sections for Coder, QA, and UX Designer templates.
- Hardened draft-review guidance around desired skills, external-system
access, secrets, and confidential advisory handling.
- Updated LLM agent-configuration guidance to point hiring workflows at
the create-agent skill.
- Added tests for bundled skill sync, create-agent skill injection, hire
approval payloads, and LLM route guidance.
## Verification
- `pnpm exec vitest run server/src/__tests__/agent-skills-routes.test.ts
server/src/__tests__/codex-local-skill-injection.test.ts
server/src/__tests__/codex-local-skill-sync.test.ts
server/src/__tests__/llms-routes.test.ts
server/src/__tests__/paperclip-skill-utils.test.ts --config
server/vitest.config.ts` passed: 5 files, 23 tests.
- `git diff --check public-gh/master..pap-2228-create-agent-governance
-- . ':(exclude)ui/storybook-static'` passed.
- Confirmed this PR does not include `pnpm-lock.yaml`.
## Risks
- Low-to-medium risk: this primarily changes skills/docs and tests, but
it affects future hiring guidance and approval expectations.
- Reviewers should check whether the new Security Engineer template is
too broad for default company installs.
- No database migrations.

## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies
> - Issue comments and documents are the main working surface where
operators and agents collaborate
> - File drops, markdown editing, and long issue descriptions need to
feel predictable because they sit directly in the task execution loop
> - The composer had edge cases around drag targets, attachment
feedback, image drops, and long markdown content crowding the page
> - This pull request polishes the issue composer, hardens markdown
editor regressions, and adds a fold curtain for long issue
descriptions/documents
> - The benefit is a calmer issue detail surface that handles uploads
and long work products without hiding state or breaking layout
## What Changed
- Scoped issue-composer drag/drop behavior so the composer owns file
drops without turning the whole thread into a competing drop target.
- Added clearer attachment upload feedback for non-image files and
image-drop stability coverage.
- Hardened markdown editor and markdown body handling around HTML-like
tag regressions.
- Added `FoldCurtain` and wired it into issue descriptions and issue
documents so long markdown previews can expand/collapse.
- Added Storybook coverage for the fold curtain state.
## Verification
- `pnpm exec vitest run ui/src/components/IssueChatThread.test.tsx
ui/src/components/MarkdownEditor.test.tsx
ui/src/components/MarkdownBody.test.tsx --config ui/vitest.config.ts`
passed: 3 files, 75 tests.
- `git diff --check public-gh/master..pap-2228-editor-composer-polish --
. ':(exclude)ui/storybook-static'` passed.
- Confirmed this PR does not include `pnpm-lock.yaml`.
## Risks
- Low-to-medium risk: this changes user-facing composer/drop behavior
and long markdown display.
- The fold curtain uses DOM measurement and `ResizeObserver`; reviewers
should check browser behavior for very long descriptions and documents.
- No database migrations.

Keep live run chain-of-thought sections in the active Working state until the run itself completes, even during gaps between command executions. Add a regression test for a running run whose latest command already has a result.

Add pb-2 inside the floating reply editor's scrollable content so the
