Owner (chat, 2026-10-01 ~22:47 UTC): "why does upaas prevent app names with dots in them?"
There is no real reason. internal/handlers/app_name_validation.go on next allows only ^[a-z0-9][a-z0-9-]*[a-z0-9]$ (2-63 characters), a DNS-label pattern. It came from the create form's HTML pattern attribute and was copied server-side under #37. Its comment says the name must be safe for Docker container names, image tags and file paths. A dot is fine in all three:
an image repository name such as upaas-sneak.berlin is valid, since . is a separator in Docker's reference grammar;
container names allow [a-zA-Z0-9][a-zA-Z0-9_.-]+;
builds/<name> and logs/<name>/... are safe as long as the name is not ., .., or begins or ends with a dot.
Definition of done:
App names may contain dots: lowercase letters, digits, hyphens and dots, 2-63 characters, starting and ending with a letter or digit, with no ... The create form's pattern and the server agree, and the error message says so.
Every place the name is used (image name upaas-<name>, container name, build and log directories, log filenames, notifications) is checked to work with a dotted name, and a test creates and deploys an app named like sneak.berlin through the image and container naming.
Pre-1.0 and only one installed instance (the owner's): nothing to migrate.

There is no real reason. `internal/handlers/app_name_validation.go` on `next` allows only `^[a-z0-9][a-z0-9-]*[a-z0-9]$` (2-63 characters), a DNS-label pattern. It came from the create form's HTML `pattern` attribute and was copied server-side under https://git.eeqj.de/sneak/upaas/issues/37. Its comment says the name must be safe for Docker container names, image tags and file paths. A dot is fine in all three:
- an image repository name such as `upaas-sneak.berlin` is valid, since `.` is a separator in Docker's reference grammar;
- container names allow `[a-zA-Z0-9][a-zA-Z0-9_.-]+`;
- `builds/<name>` and `logs/<name>/...` are safe as long as the name is not `.`, `..`, or begins or ends with a dot.

Implemented in #267: app names may contain dots, such as sneak.berlin, as lowercase letters and numbers joined by single dots or by hyphens, 2 to 63 characters. A dot next to a hyphen (a.-b, a-.b) is rejected as well as .., because Docker refuses such image names. The server check and the new and edit forms use the same rule.
