Current evaluation

PackageService API rework: remove prime_dir from pack, remove metadata, make write_metadata abstract. prime_dir is now deprecated in pack but metadata and write_metadata(path) remain unchanged. No labels, comments, or assignee in ~2 years.

Suggested action: needs triage

Reason: Filed by maintainer lengau 747 days ago with zero comments, no labels, and no assignee. Code inspection shows partial progress: pack's prime_dir param is now marked DEPRECATED in favour of LifecycleService.project_info, but the metadata property (line 209) and write_metadata(path) with its concrete implementation (line 249) are unchanged, so the core rework is still outstanding. Needs triage to decide whether to proceed with the remaining breaking API changes or close as superseded by the deprecation path.

Impact: 45 Quick Win: 13.5 Staleness: 55 Complexity: 70 Confidence: 72 Support Request: 5

Issue body

### What needs to get done - Remove `prime_dir` from `pack` - Remove `metadata` altogether - Make `write_metadata` abstract with no `path` parameter - Explain that `write_metadata` should write all metadata files into the prime directory. ### Why it needs to get done The current API no longer makes sense for all craft apps.
