CODEX HARDENS IDENTITY AND AUDIT LAYER ACROSS PLUGIN, HOOK, AND PROCESS EXECUTION

Codex shipped five infrastructure changes overnight that lock down environment isolation, plugin failure tracking, and workload identity token handling across the entire execution stack.

The biggest move is workload identity token exchange support [1], a new crate that handles short-lived credential exchange for ChatGPT federation, with token caching, refresh logic, and concurrent request coalescing to prevent thundering herds. In parallel, Codex is now blocking launch context from leaking to child processes [2], treating identity tokens and federation rule IDs as non-inheritable across execution, MCP, hooks, Git, and remote helpers. On the reliability side, plugin install failure analytics got a major overhaul [3], replacing brittle error message parsing with low-cardinality HTTP status subtypes and explicit failure signals when plugins are disabled or policy-blocked. Hook handler execution is now generalized [4], routing all handlers through the hooks engine while adding strict validation that rejects TOML-incompatible values like null in MCP tool inputs. Guardian approval reviews are fixing a timing bug [5] by using current step environments instead of stale turn snapshots, ensuring the right working directory and permission context when reviewers make decisions.
