Codex mobile approval flow breaks with codex-cli 0.104.0 (invalid elicitation result + undefined request id)

[Andy20010101]

Summary

In happy codex sessions on mobile, approval requests can get stuck and cannot be completed.
I can reproduce this in yolo mode. Logs show permission requests tracked with undefined request id, and Codex MCP
rejects the elicitation response schema.

Environment

• happy-coder: 0.13.0
• codex-cli: 0.104.0 (codex --version)
• Host OS: Windows (workspace under C:\Users\Administrator / E:\code\workflow)
• Client: Android Happy app
• Mode: yolo
• Model: gpt-5.3-codex

Steps to Reproduce

1. Start a Codex session with happy codex.
2. In mobile app, set permission mode to yolo.
3. Ask Codex to run a command that writes files (example: Remove-Item ...; Expand-Archive ...; Get-ChildItem ...).
4. Wait for approval/elicitation flow.

Expected Behavior

• In yolo (on-failure + danger-full-access), either:
  • command runs directly, or
  • approval prompt is actionable and can continue after user confirmation.

Actual Behavior

• Session stalls on approval.
• Approval cannot be completed properly from mobile.
• Logs show request id becomes undefined.
• Codex MCP returns schema error for elicitation result.

Relevant Logs

From Happy log:

[Codex] MCP message: {"type":"session_configured",...,"approval_policy":"on-failure","sandbox_policy":{"type":"danger-
full-access"}}
[Codex] MCP message: {"type":"exec_approval_request",...}
[Codex] Permission request sent for tool: CodexBash (undefined)
Agent state updated {"requests":{"undefined":{"tool":"CodexBash","arguments":{}...}}}
[Codex] Permission request not found or already resolved

From Codex MCP:

ERROR ... Invalid elicitation result:
"path": ["action"],
## Suspected Cause

In the Codex MCP bridge (runCodex module):

1. Elicitation handler expects params.codex_call_id/codex_command/codex_cwd, but current request can arrive without
   those fields.
2. Response seems to use decision, while codex-cli 0.104.0 expects action (accept|decline|cancel).

## Local Workaround (confirmed)

A local patch fixes deadlock:

- fallback toolCallId = params?.codex_call_id || randomUUID()
- map response to { action: "accept" | "decline" | "cancel" }

Could you update Happy Codex MCP compatibility for codex-cli >= 0.104.0 elicitation schema?
