-## Unreleased
-
-### Added
-
-- MacDive UDDF imports now capture dive-level fields previously dropped on
-  the floor: weather, surface conditions, boat name / captain, dive operator,
-  personal mode, altitude mode, signature, and dive-number-of-day. Site
-  metadata (water type, body of water, difficulty, flag) is also imported.
-- Cross-format import deduplication via `source_uuid` on `dive_data_sources`.
-  Stable per-dive IDs from MacDive, Shearwater Cloud, and Subsurface SSRF
-  are now preserved; re-importing the same dives in a different format no
-  longer creates duplicates.
-
-### Fixed
-
-- MacDive UDDF: equipment / gear now imports. Previously only Submersion's
-  private equipment extension was scanned, missing the standard UDDF gear
-  location (`<diver><owner><equipment>`) where MacDive and other compliant
-  exporters put it.
-- MacDive UDDF: gas switches for deco dives are now preserved. The parser
-  read `<switchmix ref>` markers in waypoints but never recorded the gas
-  reference on the sample, so downstream deco displays lost the switch event.
-- MacDive UDDF: `<equipmentused><link ref>` children are now captured from
-  both `informationbeforedive` and `informationafterdive` sections.
-- MacDive UDDF: `<surfaceintervalbeforedive><infinity/></surfaceintervalbeforedive>`
-  (first-dive marker) is now explicitly handled instead of relying on
-  silent int-parse failure.

 **Goal:** Close all current gaps in Submersion's UDDF import path when the source is a MacDive export, and add the `sourceUuid` plumbing needed for downstream MacDive XML / SQLite milestones.
 
-## Milestone 1 Status
-
-**COMPLETE** — All non-skipped tasks delivered and tested.
-
-- **Tasks landed:** 1, 2, 4, 5, 6, 8, 9, 10, 11, 12
-  - Schema v69 → v70 with `source_uuid` columns on all importable entities
-  - 10 new MacDive dive-level fields extracted (weather, boat, operator, personal mode, altitude mode, signature, dive-number-of-day, etc.)
-  - 4 new site-level fields extracted (water type, body of water, difficulty, flag)
-  - Gear import now scans standard UDDF `<diver><owner><equipment>` location, not just Submersion private extension
-  - Gas switches (`<switchmix ref>`) now recorded on samples for deco dives
-  - Equipment refs captured from both `informationbeforedive` and `informationafterdive`
-  - `<surfaceintervalbeforedive><infinity/>` explicitly handled (first-dive marker)
-  - Source UUIDs persist through import → DB on all entities
-- **Tasks skipped:** 3 (bug didn't exist), 7 (non-dive entity UUIDs descoped)
-- **Real-data validation:** User's 29MB MacDive UDDF passes regression assertions (540 dives, 373+ sites, 33+ buddies, 32+ gear)
-- **Test coverage:** 7099 tests pass, all new fields covered by unit + integration tests
-
 **Architecture:** Changes are confined to `lib/core/services/export/uddf/` (parsing), the dive-import schema migration layer, and the universal-import adapter. Additions are field-for-field extractions from `<informationbeforedive>` / `<informationafterdive>` / `<site>` plus a robustness fix for `<link ref>` disambiguation. No pipeline wiring changes.
 
 **Tech Stack:** Flutter, Dart 3, Drift ORM, `xml` package, Riverpod. Testing via `flutter_test`.
