Code Mode gets a fallback when its external host is unavailable
An in-process V8 fallback, managed Bedrock login, and paginated thread-history storage make Codex more resilient and controllable.
Code Mode can recover from an unavailable external process host, managed authentication expands to Bedrock, and Codex introduces dedicated storage for loading long thread histories in pages.
Alpha release context: 2 official tags were published that UTC day (rust-v0.145.0-alpha.2, rust-v0.145.0-alpha.3). The full comparison contains 40 commits and 271 changed files.
Evidence
Code Mode can fall back to in-process V8 when its external process host cannot be resolved.Why it matters: An unavailable external host no longer makes the whole Code Mode path unusable in environments that permit the fallback.
