Quarterly windows (29 of 41 total) diluted PC1 explained variance ratio
from ~20% down to ~14.6%. The fix splits the vector collection loop into:
- pca_vecs: annual windows only (re.match r'^\d{4}$') -> M_pca used for SVD
- all_vecs: every window -> M used for projections onto derived axes
Centering for SVD and global_mean for projection both now use M_pca.mean(axis=0)
so axes are consistent. Falls back to all windows if no annual windows exist.

A small project that uses QWEN embeddings for semantic features. The codebase includes an example Ansible package under packages/@ansible/example and helper scripts for deployment.
Embeddings
- This project uses QWEN embeddings (model:
qwen/qwen3-embedding-4b) via OpenRouter-compatible APIs. - Preferred environment variable:
OPENROUTER_API_KEYwith a fallback toOPENAI_API_KEY.
Publishing and deploying the Ansible package
- Package location:
packages/@ansible/example— this contains the Ansible playbooks and packaging used by CI. - To publish the package (CI): create a git tag for the version and provide
NPM_TOKENas a secret to the CI runner so it can publish to npm. - To deploy the package (CI): set the following repository secrets in your CI pipeline:
DEPLOY_HOST(default:motief.sgeboers.nl)DEPLOY_SSH_KEY(private key for thewebappsuser)DEPLOY_USER(default:webapps)
Defaults
- DEPLOY_HOST:
motief.sgeboers.nl - DEPLOY_USER:
webapps
See docs/deployment/ansible-package-deploy.md for more detailed deploy instructions and defaults.
