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.
Shared agent skills and their upstream attribution live in landscape/skills/. Keep upstream files unchanged; update shared workflows there, not in engineering.
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.
