fix(scaffold): preserve source in scaffold config

[jorrite]

what

• Fix atmos scaffold generate/atmos init recording a dangling, already-deleted temp-directory path in spec.source of .atmos/scaffold.yaml whenever the template source is remote (git::... or a bare https://... URL).
• In the filepkg/generator/source/resolver.go: in resolveRemote(), set conf.Source = src (the original source string the caller passed in) after loading the template configuration from the temporary download directory, instead of leaving Configuration.Source as whatever LoadConfigurationFromDir was given (the temp dir itself).
• pkg/generator/source/resolver_test.go: added/extended tests asserting Configuration.Source holds the original source for both local and remote paths, plus a dedicated regression test (TestResolve_RemoteRecordsOriginalSource) that fails on the pre-fix code and passes after.
• No change to local source handling (resolveLocal), which already recorded the correct value.

why

• For a remote scaffold source, resolveRemote() downloads the template into os.MkdirTemp("", "atmos-scaffold-"), then loaded the config with that temp dir passed in as the "source" — so Configuration.Source, and
  therefore the persisted spec.source, ended up holding something like /var/folders/xx/.../atmos-scaffold-1234567890. That directory is removed by cleanup() immediately after the command finishes, so the recorded provenance is a dangling reference to nothing as soon as generation completes — useless for anything that might want to read it back later (e.g. a future --update/re-resolve flow), and directly contradicts SaveProjectRecord's own doc comment: "spec.source and spec.baseRef record provenance for future updates."
• Local sources (a relative/absolute path, or file://...) were correct only by accident of not having a temp-dir indirection step in resolveLocal, not because anything special-cased provenance for them.
• Reproduced directly: atmos scaffold generate "git::https://.../scaffold-template.git" ./out --defaults, then cat ./out/.atmos/scaffold.yaml shows a /var/folders/...//tmp/... path for spec.source, and that path no longer exists on disk.

references

• No upstream GitHub issue — checked issue search and the web for cloudposse/atmos + spec.source/scaffold, nothing matched as of 2026-08.

Summary by CodeRabbit

• Bug Fixes
  • Remote scaffolds now retain their original source URI after resolution instead of displaying a temporary download location.
  • Local scaffold operations consistently preserve the original source path.

📝 Walkthrough

Walkthrough

The resolver now preserves the original source path or URI after local, hydrated, and remote scaffold resolution. Tests verify source preservation and remote ZIP loading.

Changes

Source provenance

Layer / File(s)	Summary
Resolver source preservation and validation pkg/generator/source/resolver.go, pkg/generator/source/resolver_test.go	Remote resolution records the caller-provided source URI instead of the temporary download directory. Tests verify local, hydrated, and remote source values. The remote test also verifies files loaded from an HTTP-served ZIP archive.
