♻️ Current situation & Problem

Revisiting the export screen resets the session, and the host receives files without a final processing result.
This change migrates to Grove, resumes exports and reports processing outcomes to the host.

⚙️ Release Notes

  • Replace didStartExport with required didStartLocalExport(attemptID, files) and didFinishLocalExport(result) callbacks. The host still handles uploads and server receipts.
  • Expose one concrete OneSecStanfordStudyModule; remove the SPI bridge, subclassing and placeholder methods.
  • Resume exports, prevent duplicate starts and retain retry state after failures.
  • Preserve reset requests during startup and clear restoration state only after completion.
  • Report concrete checkpoint errors; paused sessions remain incomplete even when all batches succeeded.
  • Default to the eight study sample types, including active energy and workouts; callers can override the list.
  • Write compressed files atomically, preserve UTC timestamps and remove source-name metadata.
  • Accept survey callbacks only from the supported HTTPS paths in the main frame.

📚 Documentation

The README and example app use the public API and cover callbacks, upload responsibilities and recovery across app launches.
Existing preference keys are retained for upgrades.

Depends on Grove #104 through feature/healthkit-export-integrity, with its temporary iOS 15 configuration and optional traits disabled.
The wrapper supports iOS 15; the study runs on iOS 18 and newer.

✅ Testing

25 study tests pass against the local Grove revision with an iOS 15 deployment target.
They cover concurrent starts, reset and startup failures, checkpoint retention, restoration and paused-session outcomes.
The shared Swift Package CI workflow reports API breaking changes without an allowlist, including its automated PR summary comment.
SwiftLint, Actionlint and REUSE pass.
The host and UI test bundle build for iOS 15; both host launch and web view alert/confirm tests pass on an iOS 26.5 simulator using the public API.
Execution on iOS 15 remains untested.

📝 Walkthrough

Walkthrough

The package migrates its framework and HealthKit dependencies from Spezi to Grove. It adds validated export configuration, default sample types, batch summaries, terminal export results, and attempt-based lifecycle callbacks. FHIR export processing preserves time instants and removes device-name metadata. Survey callback URLs now use strict parsing. WebView subframe navigation is allowed. Documentation, application integration, and tests are updated for the new APIs.

Priority: ➖ Normal

Merge Risk: 🟡 Moderate · up to 1fd8e

Export restoration and reset behavior can become inconsistent, including ignored reset requests and incorrect terminal results. These lifecycle issues should be fixed before merge.

- Around line 104-107: Update the export-start coalescing logic around
exportStartTask to track whether the existing task includes a session reset;
after awaiting an unforced task, perform the requested forceSessionReset before
returning, while preserving the current behavior when the task already resets
the session.
- Around line 123-126: Update the session-reset flow around activeExportAttempt
and deleteSessionRestorationInfo so the previous attempt remains tracked and is
not finished as .cancelled(.sessionReset) until deletion succeeds. Preserve the
existing cancellation and tracker-clearing behavior on successful deletion,
while leaving the previous attempt active if deletion throws.
- Around line 136-137: In the completed-session early-return branch, update the
preference store to clear .didInitiateBulkExport before returning. Modify the
condition handling session.state == .completed in the restoration flow; leave
the existing batch checks and return behavior unchanged.
