Problem

Codex rejects thread/resume when another app-server process already owns the thread writer. T3 currently stops the session and surfaces the provider stack trace, even though Codex can branch the conversation safely.

Fix

Detect the specific active-writer response and call thread/fork with the requested working directory, model, service tier, approval policy, and sandbox mode. T3 then stores the forked thread ID and continues from the persisted conversation history. Missing-thread fallback and unrelated resume failures keep their existing behavior.

Tests

  • vp test run apps/server/src/provider/Layers/CodexSessionRuntime.test.ts
  • vp run --filter ./apps/server typecheck
  • targeted lint and format checks for both changed files

Model: gpt-5.6-sol
Harness: T3 Code Codex
