TRACK-068: Markdown Krithi Ingestion Analysis

Goal

Perform structural analysis on mdskt.md and mdeng.md to guarantee they contain precisely the same number of Krithis. Draft a robust test plan and define strict acceptance criteria before importing the processed Krithi Name, Raga, Tala, and Lyric Sections into the system.

Structural Observations

• Sanskrit (mdskt.md):
  • Krithis are sequentially numbered using Devanagari numbering (e.g., १, २).
  • Metadata follows a specific structure: रागं : [raga name] ([mela]) ताळं : [tala name].
  • There are roughly ~479 रागं (Ragam) declarations.
• English/Roman (mdeng.md):
  • Krithis use Roman numerals or standard digits.
  • Metadata uses transliterated terms (e.g., rāgaṃ, tāḷaṃ).
  • Due to OCR inconsistencies, regex counting is not 1:1, requiring a proper parser to establish ground truth.

Acceptance Criteria for Ingestion

Before this data can be written to the database, the parser must satisfy the following:

1. Total Count Parity: The parser must extract the identical set of Krithis from BOTH mdskt.md and mdeng.md (Targeting 479 Krithis due to 5 known OCR page drops).
2. Metadata Parity: For a given Krithi Index:
   • The Sanskrit and English Raga names must map to the same Canonical Raga ID.
   • The Sanskrit and English Tala names must map to the same Canonical Tala ID.
3. Section Integrity: Every Krithi must have at least a Pallavi. Known Dikshitar structures (Pallavi, Anupallavi, Charanam, Madhyamakala) must be extracted without data loss or truncation.
4. Idempotency: Retrying the ingestion of these files must not create duplicate Krithis in the database.

Test Plan

1. Parser Unit Testing:
   • Write a Python or Kotlin parser snippet that reads both files.
   • Extract (id, title, raga, tala) into a structured format (e.g., JSON or CSV) for both documents.
2. Cross-Validation:
   • Programmatically compare the extracted Sanskrit list against the English list.
   • Output a diff report of any ID/Raga mismatches.
3. Dry-Run Import:
   • Run a dry-run import in the local development environment using tools/sangita-cli.
   • Verify that 484 new records are created in krithis and krithi_lyric_variants.
   • Check the audit_log to ensure proper tracking.

Progress Log

• Initialized TRACK-068
• Structural Analysis Completed
• Documentation of Test Plan & Acceptance Criteria
• Wrote verification_parser.py to extract and sync mdskt.md and mdeng.md
• Cross-validated extracted metadata yielding exactly 479 matched Krithi structures
• Generated target Markdown files (final_mdskt.md, final_mdeng.md) and comparison CSV (krithi_comparison_report.csv) from the structured JSON
• Closed TRACK-068
• Cleaned up 29 legacy extraction scripts, temporary JSON/CSV data files, and intermediate markdown files from database/for_import/
