[codex] run grouped projects on another machine

[aGamingGod1234]

Why

The same GitHub repository opened on two machines appeared as separate projects, and a new thread could not keep the machine-specific checkout, worktree, model, or execution context when switching between them.

What changed

• Detects matching repository projects across connected environments and shows a one-time sidebar prompt to group them or keep them separate.
• Adds a draft-only Run on combobox beside the workspace and branch controls.
• Shows each machine's path, checkout, workspace, model, provider, and execution settings in the picker, with unavailable machines visible but disabled.
• Persists a profile per physical environment/project and atomically restores it when switching A → B → A.
• Keeps started threads pinned to their original environment and project.
• Documents the grouped-project and machine-selection workflow.

Validation

• Focused web tests: 6 files, 214 tests passed.
• @t3tools/web typecheck passed.
• Targeted lint passed.
• Formatting and git diff --check passed.
• Real browser verification with two isolated T3 environments passed: duplicate repository detection, grouping prompt, machine picker details, and A → B → A switching.

Generated by GPT-5.6-Luna in T3 Code.

Note

Add per-machine draft profiles and environment switching for grouped projects

• Introduces MachineDraftProfile to store per-physical-project draft state (branch, worktree, env/runtime/interaction modes, model selections) keyed by environment+project via physicalProjectProfileKey.
• Adds composerDraftStore.switchDraftProject to atomically swap branch, worktree, modes, and model selections when switching environments on an unlocked draft, saving and restoring per-machine snapshots.
• Reworks clearComposerDraftsEnvironment to rehome grouped drafts to a surviving environment with their machine profile intact, instead of always discarding them.
• Adds buildEnvironmentOption and MachineProfileRow to surface connection state, provider/model preview, and execution settings in the desktop and mobile environment selectors.
• Adds a ProjectGroupingPrompt in the sidebar that detects repositories spanning multiple environments and lets users group or keep them separate, with acknowledgement persisted to localStorage.
• Risk: persisted PersistedDraftThreadState shape gains an optional machineProfilesByProjectKey field; existing persisted state is forward-compatible but older clients will silently drop the new field.

Two UI-consistency findings in the new components. Everything else (reuse of Select/Menu primitives, SelectPopup's popupClassName width, Button size="xs", Alert slots) composes with the existing primitives as intended.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a substantial new feature for machine-aware grouped project profiles, adding new UI components, complex state management in the draft store, and new user-facing workflows. The scope and complexity of the changes warrant human review to verify design alignment.

One finding on the mobile run-context menu width; the machine profile row and grouping prompt changes otherwise look consistent with the shared primitives.

Two findings in the new machine-profile picker UI. Details inline.

[macroscopeapp]

UI consistency review found 2 issues in the new machine profile row. Earlier findings (mobile popup width, alert action stacking, tooltip disclosure replacing aria-label) look addressed.

Closing as part of the open-PR backlog sweep (wave 1).

Reason: Abandoned 2k-line [codex] multi-machine grouping feature; conflicted since mid-August with no path.

Reopen if this is still wanted and you’re willing to rebase onto current main.
