DottaandClaude Opus 5.5 8e5959c759 fix(agents): keep pause board-only and resume grant-gated on the PATCH status route (#20164)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The board governs the agent lifecycle: pause, resume and terminate
> - The V1 permission matrix says agents may never pause an agent, and
may resume one only with a direct `agents:configure` change grant
> - `POST /api/agents/:id/pause` and `POST /api/agents/:id/resume`
enforce this, but `PATCH /api/agents/:id` with a `status` ran the same
lifecycle change after only the agent-configuration check
> - The `agents.pause-agent` chat eval caught it: the CEO agent paused
Morgan itself through `PATCH`, although the case (and the spec) expect a
board user to do it
> - This pull request applies the dedicated routes' checks to `PATCH`
status changes, as #19955 did for termination
> - The benefit is one lifecycle authority, with no second route around
it

## Linked Issues or Issue Description

Refs #19955

**What happened**

An agent that may configure another agent could pause it with `PATCH
/api/agents/{id}` `{ "status": "paused" }`, although `POST
/api/agents/{id}/pause` is board-only. The same `PATCH` with `{
"status": "idle" }` resumed an agent without the change-grant decision
and without the invalid-org-chain guard that `POST /resume` applies. In
a chat eval run, the CEO agent paused Morgan this way and reported
"Morgan is paused".

**Expected behavior**

Pause is board-only on every route (`doc/SPEC-implementation.md` section
9.3: "Pause/resume agent ... pause: no; resume: direct
`agents:configure` grant only"; "Pause, clear-error, terminate,
approval, and key-management routes remain board-only"). An agent gets
the standard final "Board access required" denial with a link to the
agent's profile. Resume through `PATCH` needs the same grant and
org-chain checks as `POST /resume`.

**Steps to reproduce**

1. As an agent with agent-configuration permission over another agent,
call `POST /api/agents/{id}/pause`. The result is 403.
2. Call `PATCH /api/agents/{id}` with `{ "status": "paused" }`. Before
this change the result is 200 and the agent is paused.

## What Changed

- `server/src/routes/agents.ts` (`PATCH /agents/:id`): `status:
"paused"` now calls `assertBoard`, the same check as `POST /pause`.
Agents get the structured `board_access_required` denial that says the
denial is final and links `/<prefix>/agents/<id>`.
- `status: "idle"` now calls `assertCanResumeAgent` (the
`agent_config:update` decision with `requiresChangeGrant`) and returns
409 with the repair guidance when the org chain is invalid, the same as
`POST /resume`.
- `server/src/__tests__/agent-permissions-routes.test.ts`: pause is
denied through both routes for an agent allowed to configure the target,
with no lifecycle change, run cancel or activity. A board user can still
pause through `PATCH`. `PATCH` idle applies the change-grant decision,
allows a granted agent, and keeps the org-chain guard.

## Verification

- `cd server && pnpm exec vitest run
src/__tests__/agent-permissions-routes.test.ts
src/__tests__/agent-cross-tenant-authz-routes.test.ts
src/__tests__/board-access-denial.test.ts`: 147 passed.
- Without the route change, three new tests fail (PATCH pause by an
agent, PATCH idle without the change grant, PATCH idle with an invalid
org chain).
- Policy evidence: `doc/SPEC-implementation.md` section 9.3 and the
`agents.pause-agent` scenario ("Pausing an agent requires board
control").

## Risks

- Non-board automation that paused agents through `PATCH` status now
gets 403. That is the intended governance boundary. Board users are not
affected.
- Agents that resumed agents through `PATCH` status now need the same
change grant as `POST /resume`. Standard agents get `agents:configure`
on creation, so ordinary behavior does not change.
- `PATCH` idle now returns 409 for an agent with an invalid org chain,
the same as `POST /resume`.
