fix(server): t3_thread_list says when its project does not exist - #29187
When an agent called t3_thread_list with a projectId that names no project, it got back a successful {"threads":[],"nextCursor":null,"total":0}. That looks exactly like a real project with no threads, so the agent concluded the project existed. t3_project_read with the same id fails with invalid_request. Reproduced on main a852de0b7b with a fresh dev server: an unknown UUID and the id not-a-project both came back as empty successes.
Change
listThreads in apps/server/src/mcp/OrchestratorMcpService.ts now checks an explicit projectId with the existing requireProject before it lists threads. A missing project fails with invalid_request "Project was not found." allProjects: true and the caller's own project, used when projectId is omitted, skip the check, as before. Three test mocks that pass a real projectId now return a project from ProjectService.getById.
New test OrchestratorMcpService thread list > refuses a projectId that names no project (apps/server/src/mcp/OrchestratorMcpService.test.ts). It fails on main with listed threads for a missing project: {"projectId":"project:missing","currentThreadId":null,"threads":[],"nextCursor":null,"total":0} and passes with the fix.
OrchestratorMcpService.test.ts, toolkits/core.test.ts and peer/PeerForwarding.test.ts pass, 84/84. vp run check:changed passes: format, lint, knip, typecheck of 3 packages, and tests in 5 files.
Runtime transcript. A scratch driver, not committed, minted a short-lived MCP client session and called /mcp on vp run dev:server, started with T3CODE_DEV_SEED=0 on a fresh database for each side.

listThreads with a projectId that names no project returns an empty list
instead of failing with invalid_request. The thread list describe now mocks
ProjectService.getById for its known projects so the existing test keeps
passing once listThreads checks the project.

Listing threads for a project that does not exist returned an empty list,
so an agent with a typo'd or stale projectId could not tell it from a
project with no threads. An explicit projectId is now checked with the
same requireProject used elsewhere and fails with invalid_request.
allProjects and the caller's own project take no extra read.

Macroscope's review found this PR approvable — Explicit project thread-list requests now report a missing project instead of returning an empty list. The change reuses existing read-only validation and leaves implicit-project and all-project queries unchanged.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
When listThreads receives an explicit projectId and allProjects is false, it checks that the project exists before listing threads. Tests cover the missing-project error and update project lookup mocks.

listThreads checks an explicit project ID with requireProject unless allProjects is true. Tests verify the invalid_request response for an unknown project ID. Affected test mocks now return project records for known IDs.

Full details: Title check
Explanation
The title names the primary change: t3_thread_list now reports when its project does not exist. It matches the changeset, which makes listThreads verify an explicit projectId with requireProject and return invalid_request when the project is missing. The title follows the conventional commit form and is specific enough for a reviewer scanning history.
Full details: Description check
Explanation
The description follows the template. The Problem section gives the expected and actual behavior with reproduction details. The Change section explains the requireProject check and the unchanged allProjects and omitted-projectId paths. The Scope and approval section links issue #29175 but gives no explanation of maintainer approval beyond the link, and the issue is described in the PR objectives as a triaged request. Verification is thorough, with a new test, before-and-after runtime transcripts, and a list of what was not checked. The model and harness line is present. The only gap is the thin Scope and approval section, which does not state whether the linked issue carries maintainer approval of direction and scope.
Full details: Linked Issues check
Explanation
Issue #29175 requires t3_thread_list to return an invalid_request failure reading "Project … was not found." when an explicit projectId names no project. The PR adds a requireProject call in listThreads for explicit projectId values, and the regression test refuses a projectId that names no project checks this failure. The incremental diff from the previous reviewed head (46a931f) to c127a20 does not change this guard. Its hunks in listThreads only change the status filter. The allProjects: true and omitted-projectId paths are unchanged. This verdict relies on the previous review's reading of the guard, because the current-head blob of OrchestratorMcpService.ts was too large to read in full. The raw summary also states that project-read errors map to orchestration_error, which this review did not verify in source.
Full details: Out of Scope Changes check
Explanation
The incremental diff from 46a931f to c127a20 adds changes that do not relate to issue #29175 and that the PR description does not mention. (1) listedThreadStatus replaces activityRunStatus ?? status in listItemFromShell and in the listThreads status filter. It reports waiting when pending background work holds completion. This changes status output and filtering for all thread lists. (2) The provider-instance refresh retry now also catches model_unavailable. (3) thread.stop now defaults the stop reason through agentStopReason, and stopDelegatedTasks receives the same value. None of these changes affects whether a project exists. The supporting tests and the ProjectService.getById mock updates do relate to the issue. The evidence does not show whether these hunks came from a merge of the base branch. Their presence in the PR diff is shown by the incremental diff only.
Resolution
Remove the unrelated hunks (listedThreadStatus, the model_unavailable retry change, and the agentStopReason default) from this PR. Move them to a separate PR with their own issue and tests. If they came from merging the base branch, confirm that and rebase so the PR diff against the merge base contains only the #29175 changes.

Call the real HTTP MCP endpoint on fresh isolated servers for each commit. Confirm not-a-project is absent, then call t3_thread_list({"projectId":"not-a-project","limit":5}) without allProjects. Repeat with an existing empty project's ID.
Missing project returns invalid_request: Project not-a-project was not found.
The existing empty project returns a successful empty list on both commits. Images are readable renderings of captured server responses, not app screenshots.
