## Thinking Path
> - Paperclip orchestrates AI agents for zero-human companies.
> - The plugin system is the extension path for optional capabilities
that should not require core product changes for every integration.
> - Plugins need scoped host APIs for issue orchestration, documents,
wakeups, summaries, activity attribution, and isolated database state.
> - Without those host APIs, richer plugins either cannot coordinate
Paperclip work safely or need privileged core-side special cases.
> - This pull request adds the plugin orchestration host surface, scoped
route dispatch, a database namespace layer, and a smoke plugin that
exercises the contract.
> - The benefit is a broader plugin API that remains company-scoped,
auditable, and covered by tests.
## What Changed
- Added plugin orchestration host APIs for issue creation, document
access, wakeups, summaries, plugin-origin activity, and scoped API route
dispatch.
- Added plugin database namespace tables, schema exports, migration
checks, and idempotent replay coverage under migration
`0059_plugin_database_namespaces`.
- Added shared plugin route/API types and validators used by server and
SDK boundaries.
- Expanded plugin SDK types, protocol helpers, worker RPC host behavior,
and testing utilities for orchestration flows.
- Added the `plugin-orchestration-smoke-example` package to exercise
scoped routes, restricted database namespaces, issue orchestration,
documents, wakeups, summaries, and UI status surfaces.
- Kept the new orchestration smoke fixture out of the root pnpm
workspace importer so this PR preserves the repository policy of not
committing `pnpm-lock.yaml`.
- Updated plugin docs and database docs for the new orchestration and
database namespace surfaces.
- Rebased the branch onto `public-gh/master`, resolved conflicts, and
removed `pnpm-lock.yaml` from the final PR diff.
## Verification
- `pnpm install --frozen-lockfile`
- `pnpm --filter @paperclipai/db typecheck`
- `pnpm exec vitest run packages/db/src/client.test.ts`
- `pnpm exec vitest run server/src/__tests__/plugin-database.test.ts
server/src/__tests__/plugin-orchestration-apis.test.ts
server/src/__tests__/plugin-routes-authz.test.ts
server/src/__tests__/plugin-scoped-api-routes.test.ts
server/src/__tests__/plugin-sdk-orchestration-contract.test.ts`
- From `packages/plugins/examples/plugin-orchestration-smoke-example`:
`pnpm exec vitest run --config ./vitest.config.ts`
- `pnpm --dir
packages/plugins/examples/plugin-orchestration-smoke-example run
typecheck`
- `pnpm --filter @paperclipai/server typecheck`
- PR CI on latest head `293fc67c`: `policy`, `verify`, `e2e`, and
`security/snyk` all passed.
## Risks
- Medium risk: this expands plugin host authority, so route auth,
company scoping, and plugin-origin activity attribution need careful
review.
- Medium risk: database namespace migration behavior must remain
idempotent for environments that may have seen earlier branch versions.
- Medium risk: the orchestration smoke fixture is intentionally excluded
from the root workspace importer to avoid a `pnpm-lock.yaml` PR diff;
direct fixture verification remains listed above.
- Low operational risk from the PR setup itself: the branch is rebased
onto current `master`, the migration is ordered after upstream
`0057`/`0058`, and `pnpm-lock.yaml` is not in the final diff.
> 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`.
Roadmap checked: this work aligns with the completed Plugin system
milestone and extends the plugin surface rather than duplicating an
unrelated planned core feature.
## Model Used
- OpenAI Codex, GPT-5-based coding agent in a tool-enabled CLI
environment. Exact hosted model build and context-window size are not
exposed by the runtime; reasoning/tool use were enabled for repository
inspection, editing, testing, git operations, and PR creation.

Expose telemetry.track through the plugin SDK and server host bridge, forward plugin-prefixed events into the shared telemetry client, and demonstrate the capability in the kitchen sink example.\n\nCo-Authored-By: Paperclip <noreply@paperclip.ing>
Remove unnecessary `as any` casts on capability strings (now valid
PluginCapability members) and add company-membership guards to match
production behavior in plugin-host-services.ts.
Wire issue document list/get/upsert/delete operations through the
JSON-RPC protocol so plugins can manage issue documents with the same
capabilities available via the REST API.

- Add scopedBus.clear() in dispose() to prevent subscription accumulation
on worker crash/restart cycles
- Use two-arg subscribe() overload when filter is null instead of passing
empty object; fix filter type to include null
- Update ASCII flow diagram: onEvent is a notification, not request/response
Plugin workers register event handlers via `ctx.events.on()` in the SDK,
but these subscriptions were never forwarded to the host process. The host
sends events via `notifyWorker("onEvent", ...)` which produces a JSON-RPC
notification (no `id`), but the worker only dispatched `onEvent` as a
request handler — notifications were silently dropped.
Changes:
- Add `events.subscribe` RPC method so workers can register subscriptions
on the host-side event bus during setup
- Handle `onEvent` notifications in the worker notification dispatcher
(previously only `agents.sessions.event` was handled)
- Add `events.subscribe` to HostServices interface, capability map, and
host client handler
- Add `subscribe` handler in host services that registers on the scoped
plugin event bus and forwards matched events to the worker
