Mergeability Score: 🟡 Moderate · up to The loader depends on a StudyDefinitions revision that does not provide the required zstd APIs, while the app still requires its Spezi 0.2 migration. This PR should not merge until those dependency and migration requirements are aligned. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 1309-1310: Align the dependency graph before selecting the
feature/study-bundle-archive branch: update MyHeartCountsShared/Package.swift
and Package.resolved to the Spezi 0.2-compatible constraints and refreshed
Spezi/FHIRModels pins, including the required migration changes; otherwise gate
the affected app targets until that migration is complete.
- Line 1294: Regenerate and commit Package.resolved so the FHIRModels pin
matches the minimumVersion 0.9.3 requirement instead of 0.8.0. Resolve the
package graph while confirming both feature-branch revisions, then verify the
updated lockfile before building.
In `@MyHeartCounts/Modules/StudyBundleLoader.swift`:
- Line 170: Add scoped defer-based cleanup for each archive URL produced by the
bundled and package-conversion paths in the study bundle loading flow. Ensure
the generated temporary archive is removed after both successful processing and
failure, while preserving the existing export and conversion behavior.

♻️ Current situation & Problem
The study bundle pipeline moves to a platform-neutral zstd archive (SchmiedmayerLab/Grove#44, SchmiedmayerLab/MyHeartCounts-StudyDefinitions#43) so the Android app can consume the same server-driven artifact. The loader still spoke Apple Archive end to end.
⚙️ Release Notes
StudyBundleLoaderdownloads, unpacks, and locally regenerates the bundle in the zstd archive format: the bucket filename followsStudyBundle.archiveFileExtension, the runtime export uses thezstdformat, and unpacking goes throughStudyBundle.unarchive. A corrupt download now correctly falls back to the bundled study.0.9.3alongside.📚 Documentation
No documentation changes.
✅ Testing
The study definition exporter — including the new
StudyBundle.archive/unarchivestack — builds for the iOS Simulator SDK, and its round-trip is covered on macOS and Linux in the upstream pull requests.Adopting the new archive API requires the study-bundle Spezi branch, which sits on Spezi
0.2; the app is still on Spezi0.1.6. Building the app therefore first needs the app's own Spezi0.2migration (renamed FHIR/HealthKit and ResearchKit products), which is separate from the study bundle and out of scope here. This PR stays a draft, scoped to the loader change, and merges once that migration lands and the upstream releases are tagged.Code of Conduct & Contributing Guidelines
