feat: zoom the day heart-rate chart and export minute-by-minute HR (closes #546) - #572
Conversation
…546) Day timeline: a range control under the HR chart zooms into any stretch of the day. The stored per-minute curve is shown by default; at two hours or less the band's per-second rows are read while they still exist, and the footnote says which resolution is on screen. Data screen: export heart rate minute by minute (timestamp, local_time, bpm, source) for a picked date range, from each derived day's stored per-minute curve. The picker is bounded to, and names, the derived days available.

**Zoomed readings use the wrong device**
When multiple devices have eligible heart-rate readings at the same second in a zoomed interval, `_readFine` queries every eligible device without applying the ownership or device-priority selection used for the stored day curve. `perSecondHr` overwrites same-second slots, so the zoomed chart shows an arbitrary device's reading instead of the selected merged value.
Apply the same device-ownership selection used for the stored day curve before passing rows to `perSecondHr`.

**CSV provenance can mismatch its curve**
When a derivation replaces a day's result and provenance between the export's source query and its per-day result query, `exportHeartRateCsv` reads provenance and the day payload separately, so it can combine the replacement curve with the previous source value. The CSV attributes heart-rate data to the wrong provenance.
Read each day's payload and its matching provenance from the same consistent database snapshot.
Also at `lib/data/csv_export.dart:498-505`.

### Comment 3

+ dayStart: 1000,
+ hr: [for (var i = 0; i < 10; i++) i.toDouble()],

+ rest: const [(0, 4, C.blue)],
+ work: const [(6, 9, C.orange), (9, 10, C.orange)],
+ );
</code_context>
<issue_to_address>
**Movement slicing goes unchecked**
When `DayGraph.window` drops or corrupts non-null movement samples, `DayGraph.window` can replace every non-null movement sample with null and the “slices every lane” test still passes: its movement fixture is all null, and the assertions check only the resulting slot count, HR, clock, and spans. The test therefore misses lost movement data.
Use non-null movement values in the fixture and assert the expected sliced movement list.
</issue_to_address>Sourcery assessment
Needs a human reviewer. 3 findings to address first, and the new export creates and shares a file containing stored heart-rate history, so a range or filtering defect could disclose the wrong health data outside the app; once a user shares it, reverting cannot recall the copy. The chart and zoom behavior otherwise produce reversible, ordinary UI defects.
Blocking findings: lib/ui2/screens/day_timeline.dart:1070, lib/data/csv_export.dart:497, test/all_hr_data_546_test.dart:13

Match the source to the served algorithm version.
exportHeartRateCsv reads the curve from the served day_result, but it reads source from a separate last-writer stamp. A lower-version rewrite can replace that stamp while the export still serves a different day_result version. The CSV can therefore report the wrong provenance.
Filter the source map to the version returned by LocalDb.dayResultVersions(). A NULL date cannot satisfy the current range predicate, so no separate null-date fix is required.

…ches its version - The zoomed per-second read applies the day's stored HR ownership (series.coverage.hr1Hz, now on the timeline payload), so a second two devices measured shows the owner's reading, as the stored curve does. - exportHeartRateCsv matches each day's source stamp to the algo_version of the day_result it read; a mismatch leaves the cell empty. The CSV renders off the UI isolate. - The export range uses dayLabelOf. - DayGraph.window test now checks the movement lane.
