codex: marshal auth.json: %w

Error message

codex: marshal auth.json: %w

What it means

Wraps a json.MarshalIndent failure while building the codex auth.json payload inside ensureCodexAuth. The payload is a trivial fixed-shape map, so this is effectively unreachable in practice; it would only fire on a non-serializable value type creeping into the payload.

Solutions

1. Treat as a programming bug — report it upstream
2. No user-facing remediation; the payload shape is static
