+# Research: IndexedDB Imports & Migrations
+
+## Hypothesis
+Chunked transactions and store-per-entity design yield responsive imports and safe migrations for 3-year datasets.
+
+## Questions
+- Import throughput (items/sec) for days vs entries
+- Optimal chunk size per transaction
+- Quota usage for 3-year dataset
+- Migration time and error handling patterns
+
+## Method
+- Use `/packages/storage/poc/import-benchmark.html`
+- Measure timings, DB size; simulate version bump
+
+## Test Matrix (fill during runs)
+| Chunk | Days(ms) | Entries(ms) | Notes |
+|-------|----------|-------------|-------|
+| 100   |          |             |       |
+| 250   |          |             |       |
+| 500   |          |             |       |
+| 1000  |          |             |       |
+| 2000  |          |             |       |
+| 5000  |          |             |       |
+
+## Acceptance
+- Import < 5s for 3-year synthetic dataset on mid device
+- Migrations complete without UI lockup and preserve data
+
+## Deliverables
+- Import strategy, migration template, data integrity checklist
