Pull request overview
This PR forward-resyncs the Chinese translation of the Aiyagari lecture to match the current upstream source (moving from the older NumPy/Numba/DiscreteDP-based implementation to the newer JAX-based structure, plus updated sections and exercises).
Changes:
- Replaced the lecture content with the upstream-aligned JAX-based implementation, restructuring sections and adding updated exercises/solutions.
- Added translation frontmatter metadata (title + heading mappings) to support consistent section translation.
- Updated translation sync state to record the upstream source SHA and resync timestamp.

The resynced file keeps Chinese plot labels but reverted the import cell to the source's exact form, losing the Source Han Serif setup - Chinese in figures would render as missing glyphs.

✅ Translation Quality ReviewVerdict: PASS | Model: claude-sonnet-5 | Date: 2026-07-18 📝 Translation Quality
Summary: This is a high-quality, comprehensive resync translation that accurately preserves the technical and mathematical content of the Aiyagari model lecture. Terminology is consistent with the glossary, code blocks and LaTeX are intact, and the prose reads fluently in academic Simplified Chinese. Only minor stylistic nuances (e.g., redundant phrasing around hyperlinks, slight loss of nuance in 'treatment') could be polished, but these do not affect overall comprehension or fidelity to the source. Mathematical notation, LaTeX equations, and code blocks are preserved accurately throughout the resynced document Technical terminology (贝尔曼算子, 价值函数迭代, 平稳分布, 随机矩阵, etc.) is consistently and correctly applied per the glossary Code comments within code cells are naturally and accurately translated without altering functional code The added 'translation' metadata block correctly maps headings without disrupting YAML validity Suggestions:

Forward Resync: aiyagari.md
Source: QuantEcon/lecture-python.myst — lectures/aiyagari.md
Source commit:
0bfcac8This PR resyncs the translation to match the current source document.
Reason: The Chinese translation is based on an entirely different, older version of the lecture. It uses numpy/numba/DiscreteDP instead of JAX, includes a completely different code implementation (Household class with populate_R/populate_Q, DiscreteDP solve), lacks the JAX-based value function iteration and Howard policy iteration exercises, omits sections like 'Implementation' subsections on primitives/operators/capital supply as structured in source, and does not include the three exercises (bisection, beta variation, HPI comparison) present in source. Conversely, it contains substantial unique content (DiscreteDP class code, populate_R/populate_Q functions, different equilibrium computation approach) not present in the source at all. This represents massive content divergence with TARGET containing unique additions not translatable back to source.
Changes
Whole-file resync applied. The entire document was resynced in a single pass.
