## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Semantic operations need a control plane that owns authorization and
state changes
> - Conformance tests need this authority without a live server or
database
> - The existing in-memory port covers transport facts but not
capability-governed domains
> - This pull request adds a deterministic capability-aware control
plane for tests
> - It keeps the implementation behind the package testing entry point
> - The benefit is repeatable authorization and mutation tests before
production wiring lands
## Linked Issues or Issue Description
**Subsystem affected**
packages/paperclip-runner testing and semantic capability contracts
**Problem or motivation**
Later semantic action slices need deterministic company, actor, task,
governance, workspace, secret, budget, routine, and audit state. A live
Paperclip server would make those tests slow and environment-dependent.
**Proposed solution**
Add serializable capability fixture types and an in-memory control-plane
adapter. Enforce company scope, claims, roles, idempotency, redaction,
faults, and audit records. Export the adapter only from the testing
entry point.
**Alternatives considered**
The tests could mock each action separately. That would duplicate
authorization rules and would not verify state transitions across
multiple actions.
**Roadmap alignment**
This supports the existing experimental Paperclip Runner rollout. It
does not enable production semantic operations or change app execution.
## What Changed
- Add deterministic capability fixture types and seed state.
- Add an in-memory capability control-plane adapter.
- Enforce run, company, actor, claim, role, and idempotency boundaries.
- Model governed task, document, interaction, workspace, secret,
routine, and audit changes.
- Add deterministic tests and testing-entry-point exports.
## Verification
- `pnpm --filter @paperclipai/paperclip-runner test:typescript`
- `pnpm --filter @paperclipai/paperclip-runner typecheck:typescript`
- `pnpm -r typecheck`
- `pnpm build`
- The branch changes 5 files relative to its declared base.
## Risks
The main risk is a permissive mock that hides a production authorization
error. The adapter fails closed for missing claims, wrong roles,
cross-company access, duplicate mutations, invalid state, and restricted
secret access. Tests cover each fixture domain and serialized restore
behavior.

with planned core work may need to be redirected — check the roadmap

## Model Used
OpenAI Codex, `gpt-5`, with agentic reasoning, tool use, and code
execution.
