feat(web): schedule tasks without a project

[sjasct]

Problem

The scheduled-task editor requires a project even though threads can already run without one. Users cannot configure a scheduled task to use the selected environment's scratch workspace from the web UI.

Change

Add No project to the existing project picker, resolving or creating the environment's scratch project when saving. Hide workspace, base-branch, and checkout-path controls for this choice and save a root workspace strategy so the server provisions a scratch folder for the task's thread.

Recognize existing scratch tasks when editing, keep the choice when switching environments, and clear a bound thread when the destination changes. Preserve the settings scope and offer the choice only when the environment supports scratch workspaces.

Before	After

Scope and approval

This is focused configuration of the existing scheduled-task and scratch-thread capabilities. It exposes the workspace choice in the shared web/desktop editor through existing client commands and server services. It requires no contract, provider, scheduler, or native mobile changes.

Verification

• vp test run apps/web/src/components/settings/scheduledTasksSettings.logic.test.ts apps/web/src/components/settings/settingsScopeNavigation.test.ts — 48 tests passed. Coverage includes first-use scratch availability, environment and project scope, and switching from each checkout strategy to a scratch workspace.
• Targeted lint and formatting checks passed for all three changed files.
• vp run --filter @t3tools/web typecheck — passed.

Implemented with gpt-6.1-sol using the Codex harness in T3 Code.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a new scratch-workspace scheduling capability and changes the editor’s default project selection when no ordinary projects are available. It also creates or resolves scratch state during save, so the product-default and runtime behavior changes warrant human review.

📝 Walkthrough

Walkthrough

Scheduled-task settings now support a “No project” choice when the environment and scope allow it. Saving that choice opens Scratch and uses its project ID. The settings use a root workspace strategy for no-project tasks.

Changes

Scheduled tasks without a project

Layer / File(s)	Summary
Project choices and draft state apps/web/src/components/settings/scheduledTasksSettings.logic.ts, apps/web/src/components/settings/ScheduledTasksSettings.tsx, apps/web/src/components/settings/scheduledTasksSettings.logic.test.ts	Helpers filter project choices by environment and scope, determine whether “No project” is available, and select a default. The draft represents “No project” with null. Tests cover eligibility and defaults.
No-project selection controls apps/web/src/components/settings/ScheduledTasksSettings.tsx	The selector offers “No project” when allowed and recalculates the selection when the environment changes. Workspace and checkout controls are hidden when no project is selected.
Scratch resolution and workspace strategy apps/web/src/components/settings/ScheduledTasksSettings.tsx, apps/web/src/components/settings/scheduledTasksSettings.logic.ts, apps/web/src/components/settings/scheduledTasksSettings.logic.test.ts	Saving a no-project task opens Scratch and uses the returned project ID. The workspace strategy helper returns a root strategy for no-project drafts. Tests cover workspace strategy selection.

Merge Risk

Merge Risk: ⚪ Minimal · up to 7d936

No-project saves are wired to Scratch and its per-thread workspace. The review found a gap in tests for that save path, but no established failure that should block merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 7d936

The new destination uses existing permissions and server-managed workspaces. No new authorization bypass or privilege expansion was identified in the inspected flow. Recovery and deployment coverage remains incomplete.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The new branch reaches filesystem setup and subsequent scheduled execution in the selected environment through existing operator-authorized services. Its inspected input contains an environment identity and task configuration, not a caller-chosen Scratch root. Per-thread folders do not themselves establish sandboxing or reduced agent/tool privileges.

Trust Boundaries and Controls

• observed — Scratch ensure and task upsert both require orchestration-operate authority. The WebSocket server authenticates the session and installs per-RPC authorization using that session’s scopes. These controls predate the PR and remain in place for the new caller; settings-picker scope is not the server authorization boundary.
• observed — The No project branch passes an empty Scratch payload and forces a root strategy instead of carrying an existing-worktree path. Server-managed project folders determine the Scratch root and bootstrap or reuse its project identity.

Resilience and Maintainability Implications

• inferred — Scratch setup and task upsert are separate operations. Failure or interruption after setup can leave the shared Scratch project without a saved task, but retry reuses that project rather than requiring rollback of a task-specific resource. Existing conflict handling and static tests support convergence across concurrent creation and folder recreation.

Review comments at @apps/web/src/components/settings/ScheduledTasksSettings.tsx:
- Line 1003: Update the destination-switch assignment to `projectId` so
switching from No project to an environment without an available Scratch
workspace clears the stale `null` selection. Reset to an available project or an
unset selection when No project cannot be offered, while preserving `null` only
when that option is supported.
- Line 835: Update the draft destination selection so the default displayed by
the dialog is stored and remains unchanged if projects load later; require an
explicit user selection before switching from No project to a project. Anchor
the change to the draft.projectId fallback that reads projects[0]?.id.

268-279: 📐 Maintainability & Code Quality | 🔵 Trivial | 🏗️ Heavy lift

Add a submit-path test for No project.

When a user submits with No project, the handler calls openScratch, uses its returned project ID, and sends a root strategy to upsertTask. The changed test only calls workspaceStrategyFromDraft directly. Add a component-level test that asserts the complete upsertTask payload. Without it, a submit-handler regression can pass while the helper test remains green.
