Document Archive (documents/)

The documents/ folder is an archive of personal documents (PDFs, images, etc.) with markdown transcriptions alongside each file. The entire vault (not just documents/) is indexed by the notesearch skill (LlamaIndex + Ollama vector search).

Transcription Convention

• Each original file has a matching .md transcription alongside it (e.g., lu_w2_meta_2025.pdf + lu_w2_meta_2025.md)
• The .md file is a faithful full transcription of the source — every data point preserved, not a summary
• Exception: immigration/ subfolders use a single summary.md per subfolder instead of per-file transcriptions, because immigration petitions reuse many of the same supporting docs

File Naming Convention

{person}_{doctype}_{year}.{ext}

• person: lu, jiang, nichol, xue, or omit if joint/obvious
• doctype: descriptive snake_case (e.g., w2_meta, dl_ca, eye_exam)
• year: 4-digit year, or YYYY_MM if needed for disambiguation
• ext: always lowercase

Frontmatter Taxonomy

Every .md transcription has YAML frontmatter with these fields:

---
category: tax
type: tax-form
person: Yanxin Lu
date: 2025
source: lu_w2_meta_2025.pdf

Search

The vault is indexed by notesearch (LlamaIndex + Ollama embeddings). Search is semantic — query by meaning, not keywords. The index lives at .index/ and is rebuilt on the blade server after git pull.

Only .md files are indexed. Original binary files (PDFs, images) are not directly searchable but their content is captured in the .md transcriptions.
