Summary: The Implementation section is translated accurately, fluently, and with consistent terminology. Code blocks, math, and MyST directives are preserved correctly with no syntax errors. No notable issues found in the changed section. Implementation section translation is accurate and preserves all code, math, and technical meaning Consistent terminology usage matching the rest of the document (e.g., 策略函数, 解包, 求根) Proper full-width punctuation and spacing conventions followed throughout the changed section

Summary: The translation sync correctly applied the RNG modernization change (np.random.seed/randn → default_rng/standard_normal) in the same file, same location, and preserved headings and metadata, with only a trivial extraneous blank-line removal elsewhere.

Issues:

• An extra blank line between 'Examples are given below.' and '## Implementation' was removed in the target's After version, but this was not a change present in the source document (source kept two blank lines). This is a minor unintended structural deviation but does not affect rendering significantly.

Pull request overview

This automated translation-sync PR updates the Chinese lecture content for os_time_iter.md to reflect the upstream change from legacy np.random seeding/state to NumPy’s Generator API, and refreshes the translation state metadata accordingly.

Changes:

• Replaced np.random.seed + np.random.randn with np.random.default_rng(seed) + rng.standard_normal(...) in the lecture’s model construction example.
• Cleaned up minor markdown formatting (removed an extraneous blank line; normalized the {solution-end} fence closing).
• Updated translation sync state metadata (source-sha, synced-at, model, mode, tool-version).

Reviewed changes
