feat(settings): providers can be turned on or off per project

[yordis]

Problem

With a project selected, Settings > Providers reads as if a provider can be turned off for that project, but the switch changes the whole machine. Turning a provider off for one repository silently turns it off for every project on that environment, and there is no way to turn on a provider for one project while it stays off for the machine.

Change

• Projects get a per-instance provider override (projectSettingsOverrides[projectId].providerInstances) that falls back to the machine value when unset. The Providers page writes it when a project is in scope, for every checkout of that project on the selected machine, and offers a reset back to the machine value.
• The server enforces the effective value wherever a turn can start: new threads, sends, queued messages, follow-ups from delegated tasks, agent-started child threads and delegations over MCP, and scheduled tasks. A turn already running when the switch flips finishes, and a delegated task's result still lands in its parent thread. A command receipt skips the check so retries still replay.
• Clients that predate the override keep a project's stored value when they save other project settings, and deleting a project drops its override so it does not linger in settings.
• A machine-disabled instance that some project turned on stays running, so that project can still use it.
• Text generation moves to a fallback instance when its configured instance is off for the project, using the same fallback order as the machine-level guard. Machine-level fallback is unchanged.
• Web and mobile pickers, automatic routing, and send paths read the per-project value. On mobile, sending a model the project turned off puts the message back in the composer and points the user to the project's provider settings instead of asking them to set up the provider.

Scope and approval

There is no linked issue. Project-scoped settings overrides and the project scope on the Settings page already exist; this makes the provider switch that page already shows apply to the selected project instead of the whole machine. It adds no new settings surface or workflow.

Verification

• vp test run on the touched suites: packages/shared/src/projectSettings.test.ts, apps/server/src/mcp/OrchestratorMcpService.test.ts, apps/server/src/orchestration-v2/ThreadMessageIntake.test.ts, apps/server/src/orchestration-v2/ThreadManagementService.test.ts, apps/web/src/components/settings/ProviderSettingsPanel.logic.test.ts, apps/web/src/components/settings/settingsScope.test.ts, apps/mobile/src/lib/modelOptions.test.ts, apps/mobile/src/state/thread-outbox.test.ts. All pass.
• The new tests cover: a project turning off a machine-enabled instance and turning on a machine-disabled one; retries replaying past the gate; driver-only delegation skipping a turned-off instance; text generation falling back for the project only; the override being written to every checkout of a project; and mobile refusing to send a model the project turned off, for any provider.
• tsc --noEmit for server, web, and mobile, plus targeted lint on changed files, report no errors.
• Screenshots below are from the desktop client.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a broad project-scoped provider capability across persisted settings, server orchestration, provider lifecycle, MCP/queue handling, web, and mobile clients. It also changes effective model fallback/default behavior for affected projects, so the cross-cutting runtime and product behavior warrant human review.

🟠 Major · Use project enablement when selecting an automatic-routing destination. · ChatView.tsx:4359

apps/web/src/components/ChatView.tsx:4359
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Use project enablement when selecting an automatic-routing destination.

When a project enables an instance disabled at machine level, Line 4359 still rejects that machine. When a project disables an instance enabled at machine level, the filter can offer that machine and the server can reject the send. Resolve enablement for the candidate’s projectId and settings instead of reading provider.enabled. This unchanged filter becomes inconsistent with the new project-aware entries at Line 3250.

Hi! We are cleaning up open PRs, and this one does not say which model or harness was used to create it. If this change is really important, we recommend rebuilding the PR with a newer model and noting the model and harness in the PR description.

[juliusmarminge]

Approving after re-audit. Every item from the earlier change request is addressed:

• Enforcement now sits at the ThreadManagement.dispatch chokepoint for message.dispatch and delegated_task.request, with a queue-start hold in startNextQueuedRun as the second layer. Refused internal wakes are handled rather than crashed: delegated completions are acknowledged so results still land in the parent, continuation offers get cleared, and the docs state the queued/in-flight semantics precisely.
• Mixed-version is covered in both directions: older clients keep a stored providerInstances they do not mention ({} clears explicitly), and the projectProviderInstanceOverrides capability flag hides the switch against older servers.
• Orphaned overrides are cleared on project deletion plus a boot-time sweep for leftovers.
• PR body refreshed with desktop screenshots; projectId is required at the resolver call sites; the text-generation fallback widening was reverted for the machine-level caller; mobile refusal copy points at web/desktop.

Rebase note (done by me, just now): I rebased the branch onto current main (c09c235). Two things worth knowing about the replay:

• A plain rebase drops changes that were introduced while resolving merges with main. I verified the rebased tree against a merge tree of the audited head and restored what replay lost — the mobile thread-settings-sheet projectId threading, updated model-visibility test calls, and ServerSettings test layers — in d2cafa2. The final tree matches the merge tree byte for byte outside that commit's intent.
• Current main's review-guide resolver (resolveReviewGuideModelSelection) called the writer-model resolver without the now-required projectId. I cherry-picked a536ac8 ("review guides skip providers a project turned off") from the local landing stack so review guides resolve per project instead of passing null.

Verification on the rebased head: 447 tests across the 13 touched suites pass; tsc --noEmit is clean for server, web, and mobile; targeted lint on the conflict-touched files reports 0 errors. Full CI is re-running on this head.

Non-blocking residuals from the re-audit, for the record: the enablement rule now has a third inline copy in the queue-start hold; overrides naming a deleted instance linger harmlessly (hydration ignores absent instances); and when a project turns every instance off, text generation keeps its disabled selection, mirroring the pre-existing machine-level guard.

_{Re-audit and rebase performed at maintainer request by Muse Spark via Muse Code in T3 Code. Audited head 0ad9e5e; rebased head 5b257f4.}
