Summary: The translation of the modified sections is accurate, fluent, and terminologically consistent with the provided glossary. Mathematical formulas, code blocks, and MyST directive syntax are all correctly preserved with no structural or syntax errors. Only minor stylistic refinements could improve naturalness in a couple of sentences, but these do not affect comprehension or correctness. Mathematical notation, LaTeX equations, and code blocks are fully preserved without alteration Technical terminology (Leontief inverse, eigenvalue, Markov chain, input-output matrix) is translated consistently and matches the provided glossary Code comments and print statements are accurately translated while keeping code syntax intact Academic register and formal tone are maintained consistently throughout the changed sections

Suggestions:

• [minor · terminology] lecture.md — ### Applications in Economics (Matrix Operations): The glossary specifies 'Input-output model' → 'مدل داده-ستانده', and the translation uses 'روابط داده-ستانده' for 'Input-output relationships', which is consistent, but 'جدول‌های داده-ستانده' for 'input-output tables' earlier is also fine. No actual inconsistency found, but worth confirming 'سیستم‌های لئونتیف' for 'Leontief systems' is an acceptable rendering since it is not in the glossary; tran…
• [minor · fluency] lecture.md — ### کاربردها در اقتصاد (Vector Spaces): The sentence 'ویژگی بسته بودن تضمین می‌کند که ترکیب‌های تخصیص‌های امکان‌پذیر، امکان‌پذیر باقی می‌مانند' is slightly repetitive/awkward due to repeated 'امکان‌پذیر'; could be smoothed for better flow while preserving meaning. → ویژگی بسته بودن تضمین می‌کند که ترکیب تخصیص‌های شدنی همچنان شدنی باقی بماند
• [nit · fluency] lecture.md — ## Matrix Operations: The phrase 'نظریه سبد دارایی' translates 'portfolio theory' reasonably, but a more standard academic Persian economics term often used is 'نظریه پرتفوی' or 'نظریه سبد سهام'; current choice is understandable and not incorrect.

What changed in this PR

This is an automated translation-sync PR that propagates source changes from QuantEcon/test-translation-sync#985 into the Farsi (fa) target repository. It updates the existing Farsi translation lecture.md and adds the per-file translation state metadata file .translate/state/lecture.md.yml. It fits into the repository's translation-sync workflow, where each tracked document has a companion state file recording sync metadata.

Changes:

• Expands several Farsi paragraphs in lecture.md with additional economic context and adds new bullet points (vector-space properties, matrix applications, eigenvalue applications).
• Adds .translate/state/lecture.md.yml recording source SHA, sync date, model, mode, section count, and tool version.

File	Description
lecture.md	Updates Farsi translation text for several sections to match the expanded English source; markdown structure and headings remain intact.
.translate/​state/​lecture.md.yml	New state file capturing sync metadata (source-sha, synced-at, model, mode, section-count: 3, tool-version).

Verification notes:

• section-count: 3 matches the 3 top-level headings in lecture.md's front matter translation.headings (Vector Spaces, Matrix Operations, Eigenvalues and Eigenvectors), consistent with the established convention.
• source-sha (142885b...), model (claude-sonnet-5), and mode: UPDATE are consistent with the PR metadata and the fact that lecture.md is an update to an existing file.
• synced-at: "2026-10-09" matches the current date and is not a future date.
• No code logic is touched; changes are translation content and metadata only.

No issues were found that warrant inline comments.
