Conversion Calibration System (TRANSMUTE)

Purpose: Use this reference after conversion work to record outcomes, evaluate quality trends, and update tool/template heuristics safely — the cross-conversion learning loop. Pair with: quality-assurance.md for the per-conversion scoring inputs that feed this loop (4-metric weights, A-F grade definitions, verification commands, report template). The Quality_Score block in the record schema below uses the metrics defined there.

EVALUATE — Quality Thresholds

Per-conversion grade scale (A/B/C/D/F at 90/80/70/60) is defined in quality-assurance.md. For trend interpretation across many conversions, use the same boundaries: averages ≥ 90 = excellent, 80-89 = maintain current approach, 70-79 = review tool/template choice, < 70 = investigate root causes.

Tool effectiveness:

Example defaults:

markdown_to_pdf:
  pandoc_xelatex: 0.95
  # pandoc_wkhtmltopdf removed — EOL since 2023, do not use (see SKILL.md Critical Decision Rules); use pandoc_weasyprint
  pandoc_lualatex: 0.90
word_to_pdf:
  libreoffice: 0.90
  pandoc: 0.65
html_to_pdf:
  chrome_puppeteer: 0.90
  # wkhtmltopdf removed — EOL since 2023, do not use (see SKILL.md Critical Decision Rules); use weasyprint
  pandoc: 0.60

CALIBRATE — Rules

1. Require 3+ conversions before changing a heuristic.
2. Limit each adjustment to ±0.15.
3. Decay adjustments 10% per quarter toward defaults.
4. User-explicit tool preference overrides calibration.
