DottaandPaperclip 5db5734774 fix(plugins): scope operational reads to the caller's companies (#17435)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - One instance hosts many companies, and company boundaries are the
main isolation contract
> - Plugin worker logs, job runs and webhook deliveries store a
`company_id` attribution (NULL for instance scope)
> - The plugin diagnostics routes checked board org access, but they did
not filter those rows by the caller's companies
> - A board member of one company could therefore read another company's
log messages, run errors and delivery errors
> - This pull request scopes those reads to the caller's companies and
keeps the instance-wide view for instance administrators
> - The benefit is that plugin diagnostics obey the same tenant boundary
as the rest of the plugin routes

## Linked Issues or Issue Description

**What happened?**
A board user who is a member of only company A could read plugin
operational rows attributed to company B. `GET
/api/plugins/:pluginId/logs` returned log rows with `company_id` values
outside the caller's companies. `GET
/api/plugins/:pluginId/jobs/:jobId/runs` returned other companies' run
rows, including their error text and run logs. `GET
/api/plugins/:pluginId/dashboard` returned other companies' recent job
runs and webhook deliveries. The routes only required board org access
and filtered on plugin id or job id.

**Expected behavior**
A board member sees only operational rows for companies the member can
access. An instance administrator (and the local implicit board) keeps
the instance-wide view, which includes instance-scope rows where
`company_id` is NULL.

**Steps to reproduce**
1. Create two companies, A and B, on an authenticated instance.
2. Install a plugin and produce a log row, a job run and a webhook
delivery for company B.
3. Sign in as a board user who is a member of company A only.
4. Call `GET /api/plugins/:pluginId/logs`, `GET
/api/plugins/:pluginId/jobs/:jobId/runs` and `GET
/api/plugins/:pluginId/dashboard`.

Before this change, the responses included company B rows. After this
change, they do not.

**Paperclip version or commit**
Reproduced on `2e6d3f7` (`master`, 2026-10-24). The report came from a
scoped security audit of `52a66af29ddccf1fcac25f1f6efa9e9958e11fbd`.

**Deployment mode**
Self-hosted server, authenticated mode. The defect does not depend on
the deployment mode, but `local_trusted` always yields an instance-admin
actor and hides it.

## What Changed

- Added `pluginOperationalReadCompanyIds()` in
`server/src/routes/plugins.ts`. It returns `null` for instance admins
and the local implicit board, and the actor's company ids for every
other board actor.
- Scoped `GET /api/plugins/:pluginId/logs` with
`inArray(pluginLogs.companyId, companyIds)`.
- Scoped `GET /api/plugins/:pluginId/jobs/:jobId/runs` through a new
optional `companyIds` argument on `pluginJobStore.listRunsByJob()`.
- Scoped the dashboard's recent job runs through the same optional
argument on `pluginJobStore.listRunsByPlugin()`, and scoped its webhook
delivery query.
- Added
`server/src/__tests__/plugin-operational-reads-tenant-scope.test.ts`. It
starts embedded Postgres, seeds two companies plus instance-scope rows,
and asserts the single-company view and the instance-admin view for all
three routes.

## Verification

- Red first: with the test added and the route unchanged, 3 of 4 cases
failed and the response contained the company B rows.
- Green after the fix: `pnpm exec vitest run
server/src/__tests__/plugin-operational-reads-tenant-scope.test.ts`
passed (4 tests).
- Related suites: `pnpm exec vitest run
server/src/__tests__/plugin-routes-authz.test.ts
server/src/__tests__/plugin-tenant-isolation.test.ts
server/src/__tests__/plugin-install-route-security.test.ts` passed (59
tests).
- Typecheck: `pnpm --filter @paperclipai/server typecheck` passed.

## Risks

- Behavior change for non-admin board members: they no longer see
instance-scope rows (`company_id` NULL) or rows for companies they
cannot access. Instance administrators keep the full view. For a
single-company instance the visible rows are the same, except
instance-scope rows.
- No schema or migration change. No API shape change. Row-level
filtering only.
- A plugin that writes diagnostics without a `company_id` will show
fewer rows to non-admin users. That is the intended tenant boundary.

## Model Used

- Provider: OpenRouter
- Model: `deepseek/deepseek-v4.1-flash-1017` (DeepSeek V4.1 Flash)
- Harness: OpenCode, with tool use, code execution, and multi-agent
delegation
- Reasoning: enabled (thinking mode)
- Context window: not exposed by the harness
