Engineering guidance

Edit resources/ as the source; generated copies in applications are consumers.
Read resources/CODING_STANDARDS.md before changing Java; project architecture and metrics apply to consumer backend modules as documented there.
Keep upstream skills unchanged and retain resources/skills/upstream.json and licenses.
Keep project-specific configuration, secrets and waivers out of shared defaults.
Run the bootstrap, formatter, CI/release regression and generated-example checks.
Never move a published release tag. Document consumer-file changes in UPGRADING.md.
Architecture and specifications belong to the landscape repository.
