party2d_estimates agent notes

For repositories on git.seimel.app, use the existing Tea/Gitea token from ~/.config/tea/config.yml for authenticated git push/git fetch operations.
Do not print, log, or expose the token.
Prefer token-authenticated HTTPS over unauthenticated HTTPS or SSH when pushing to git.seimel.app.
Python is forbidden for this project. Public workflow code and documentation must use R, Julia, Stan, and shell only; do not add Python scripts or Python references.
data-setup/run_data_setup.sh is intentionally a no-option public entry point. It downloads script-accessible sources, checks local raw files, rebuilds generated inputs under _local/, compares them to committed data/, and never replaces committed inputs automatically.
