Resolve the operational/config sprawl (#10-#14 from the review): the app read
NORMOGEN_*/MONGODB_* env vars but every env/compose file set SERVER_*/DATABASE_*,
the ports were all over the place (8080/8000/6500/6800), there were 5
inconsistent Dockerfiles (rust:1.82 vs rust:1.93, missing curl), and an 18 MB
binary was committed.
Env-var names — standardize on what the code reads:
* config/mod.rs: NORMOGEN_PORT default 8080 -> 6500 (avoid the over-common
8000/8080).
* db/mod.rs: create_database() now reads MONGODB_DATABASE (was DATABASE_NAME).
* .env.example, defaults.env, docker-compose.yml, docker-compose.dev.yml,
DEPLOYMENT_GUIDE.md, deployment/README.md, deploy-and-test-solaria.sh,
deploy-local-build.sh: use NORMOGEN_HOST/NORMOGEN_PORT/MONGODB_URI/
MONGODB_DATABASE/APP_ENVIRONMENT; drop the dead SERVER_*/DATABASE_URI/
DATABASE_NAME names.
Ports — canonical container port 6500 everywhere:
* Both Dockerfiles EXPOSE 6500; prod compose maps 6500:6500, dev 6501:6500.
* Bulk-replaced the long tail of solaria:8000/localhost:8000/localhost:8080 in
docs and test scripts -> 6500.
Dockerfiles — 2 canonical, rust:latest, curl + healthcheck:
* backend/Dockerfile (prod): rust:latest builder, debian runtime now installs
curl (so the compose HEALTHCHECK actually works), EXPOSE 6500.
* backend/docker/Dockerfile.dev (dev): rust:latest both stages, EXPOSE 6500.
* Deleted 3 redundant Dockerfiles (Dockerfile.improved x2, docker/Dockerfile).
* Deleted the committed 18 MB binary backend/docker/normogen-backend.
* Deleted 2 stray fix-notes in backend/docker/.
Compose:
* docker-compose.yml: correct env names, 6500:6500, APP_ENVIRONMENT=production,
JWT_SECRET/ENCRYPTION_KEY required via compose interpolation, dropped the
obsolete top-level version: key.
* docker-compose.dev.yml: correct env names, 6501:6500, mongo:7 (was 6.0),
added a working backend healthcheck.
* Deleted docker/docker-compose.improved.yml + backend/deploy-to-solaria-improved.sh
(built around the now-deleted 'improved' Docker files).
Verified: cargo fmt --check clean, build + clippy --all-targets clean, 18 unit
tests pass; grep confirms no SERVER_*/DATABASE_* env names and no rust:1.x tags
remain outside docs/archive and docs/adr (historical).
