# Code Review: Step 2 — Prepare safe credentials and isolated Codex config

## Verdict

Approved. No blocking findings.

## Findings

None.

## Verification performed

- Reviewed the changed file list with `git diff 80dba94de4dcf2d359d21cccc5ae5c89f7726839..HEAD --name-only`.
- Reviewed the full diff with `git diff 80dba94de4dcf2d359d21cccc5ae5c89f7726839..HEAD`.
- Read `PROMPT.md` and the updated `STATUS.md` for Step 2 context.
- Checked the tracked diff for credential assignments; no `INTERVALS_ICU_*=` values were introduced in the task files.
- Confirmed `.env` is not tracked by Git and is absent in this worktree.
- Ran `git diff --check 80dba94de4dcf2d359d21cccc5ae5c89f7726839..HEAD`; no whitespace errors were reported.

## Non-blocking notes

- `STATUS.md` safely records credential availability as unavailable without exposing values.
- The documented strategy continues to prefer transient Codex MCP configuration and avoids editing persistent Codex config, which matches the Step 2 guardrails.
- Because `.env` is absent, later live intervals.icu validation will need either a safe credential source to be provided or a clearly documented blocker for the real-data portion.
