## Thinking Path
> - Paperclip orchestrates AI-agent companies through a company-scoped
control plane.
> - Plugins extend that control plane, but plugin workers still call
back into host APIs.
> - Those worker-to-host calls need the same company boundary guarantees
as normal API routes.
> - Plugin action handlers also need authenticated actor context from
the host instead of trusting caller-supplied params.
> - This pull request hardens plugin bridge/action scope and keeps
plugin operation issues out of normal issue surfaces.
> - The benefit is safer plugin execution with clearer authorization
boundaries and better test coverage.
## What Changed
- Added host-owned invocation context plumbing for nested plugin worker
calls.
- Added actor context to plugin `performAction` calls and test harness
helpers.
- Enforced company invocation scope on worker-to-host calls and filtered
company lists to the active invocation scope.
- Extended plugin action route tests for board and agent actor context,
spoofed company params, and cross-company rejection.
- Extended plugin worker manager coverage for invocation-scope
propagation.
- Filtered typed and legacy plugin operation issue origins from default
issue/inbox lists.
## Verification
- `pnpm --filter @paperclipai/plugin-sdk build`
- `NODE_ENV=test pnpm exec vitest run
packages/plugins/sdk/tests/host-client-factory.test.ts
packages/plugins/sdk/tests/testing-actions.test.ts
server/src/__tests__/plugin-routes-authz.test.ts
server/src/__tests__/plugin-worker-manager.test.ts
server/src/__tests__/issues-service.test.ts`
Note: embedded Postgres issue-service tests reported host-level Postgres
init skip for 47 tests; the non-embedded targeted tests passed.
## Risks
- Medium: plugin host authorization paths are sensitive, and external
plugins may rely on previously loose company params.
- Mitigation: the change only tightens calls when the host attached a
company invocation scope and includes explicit tests for board, agent,
and nested worker calls.
