When a thread's permission mode is one its provider does not offer, T3 Code ran it, and the web and mobile pickers showed it, as Supervised, the narrowest mode. With the default set to Auto, a new Pi thread (Pi offers Supervised, Auto-accept edits and Full access) showed "Supervised" and asked for approval before every file write. delegate_task and t3_thread_launch already step down to the broadest mode the provider offers.
Reproduced on main at a185dd9248 with the web dev server and a fresh database: Settings → Threads → New threads → Permissions set to Auto. New thread, model switched to Pi. The composer reads "Permissions: Supervised", and Pi's write tool call waits for approval. The thread is stored as auto and runs as approval-required.
broadestRuntimeModeWithin(mode, supported) in packages/contracts/src/providerPolicy.ts returns the broadest supported mode that grants no more than mode.RuntimePolicy.ts providerRuntimeMode), the web composer (resolveCompatibleRuntimeMode) and mobile thread settings (compatibleRuntimeModeForChoices) use it in place of their narrowest-mode fallback. When nothing at or below the mode is offered, they still fall back to the narrowest mode, so a thread never runs above the mode it was set to.delegatedTaskModes.ts drops its private rank switch and uses the same helper and isRuntimeModeAbove. Its error for an explicitly requested unsupported mode now names the mode the thread would actually run in.Fixes pingdotgg/t3code#30538

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — Unsupported thread permission modes now fall back to the broadest supported lower mode instead of Supervised. This can remove approval prompts for existing threads, requiring human confirmation of the changed permission expectations.

Runtime mode resolution now selects the broadest provider-supported mode that does not exceed the requested mode. This applies to mobile and web thread settings, server provider policy, and inherited delegated tasks. Tests and documentation describe the updated mappings.
Changes: Runtime mode fallback

Thread settings and server provider policy use this selection. Tests and provider documentation cover the resulting mappings, including Auto resolving to Auto-accept edits for Pi and Antigravity. |
Delegated task mode resolution apps/server/src/mcp/delegatedTaskModes.ts, apps/server/src/mcp/OrchestratorMcpService.ts, apps/server/src/mcp/toolkits/project/handlers.test.ts | Delegated runtime-mode checks use the shared comparison helpers. Inherited unsupported modes resolve to the broadest supported mode within the limit, or approval-required if no mode qualifies.

Explanation
The description covers the problem, implementation, scope, and verification in detail. It links the issue but does not state that a maintainer approved the scope or explain why the fix qualifies for an exception; the rest of the description is complete.
Explanation
Issue #30538 requires a new Pi thread with stored mode Auto to run in Auto-accept edits rather than Supervised. The reviewed implementation still applies broadestRuntimeModeWithin in the server and web mode selection paths. The server regression test still checks the Pi Auto case. The current head removes the web and mobile wrapper tests, but the shared selection rule and server test remain. The issue’s suggestion to make the fallback selectable is optional and is not a coding requirement.
Explanation
The changes remain connected to the provider mode step-down behavior in issue #30538. The incremental changes remove redundant web and mobile wrapper tests while retaining the server regression test. The provider-authoring documentation describes the same behavior. No unrelated change is shown.

Environment on both sides: real web dev app/server, Linux/Chrome, 1280×800 CSS viewport, dark theme, separate fresh databases, identical empty synthetic projects. Runtime model labels are redacted.
Steps: enable authenticated Pi; set the new-thread default to Auto with no project override; create a Pi thread; request creation of note-30538.txt through the write tool; after completion request printf 'shell-30538\n' through bash. Approve the write only if requested so both sides reach the shell request.
| Before | After |

| d290c1f1b6 | b6eaa87914 |
| Before: Auto-default Pi draft displays Supervised | After: Auto-default Pi draft displays Auto-accept edits |
| Full interaction recording: write waits for approval; after manual approval, shell also waits. | Full interaction recording: write completes automatically; shell waits for approval. |
Both real threads retained stored Auto. Runtime observation, inspection script, browser action recipe, seed script, capture rendering script.
