health: surface imported WHOOP blood oxygen as a suppressed metric row - #472
Conversation
The WHOOP importer has stored spo2 scalars/series since the export import landed, but nothing could see them: no spec, no catalogue row. The band's own red/IR ADCs stay refused as a saturation source (kSpo2Refusal is a property of the bytes, not a firmware gap) — this only exposes the vendor's own derived value from the CSV, suppressed rather than charted so band-derived and vendor-imported points are never mixed under one line with no provenance axis. DerivationEngine's series map still does not list the key, so a re-derive can never fabricate or blank one. Co-authored-by: BucciMobile <BucciMobile@users.noreply.github.com>

The WHOOP 5.0/MG v18 record carries an SpO2 estimate/status byte at inner[74] every second; the app decoded it and threw it away. This banks the byte in decoded_onehz.spo2_candidate_raw so the capture exists from now on — the encoding is NOT pinned (nonzero only during band-declared sleep, clusters 95-99, bit 7 a suspected flag, no validity bit), so nothing may read it as a percentage or build a metric on it. Same contract as ts_subsec/band_sleep_state: off-ladder column via _ensureDecodedOneHzBandFields, omitted-when-null on the write, raw 0 (the band's own no-sample) preserved verbatim on gen5, null on gen4. The kSpo2Refusal on the gen4 red/IR pair is untouched. When the encoding is pinned against a real capture, the history is already there.

A suppressed spec loaded no series at all, so the catalogue row could not show what the importer had written. An importedValues flag lets the spo2 spec load its stored series and render it as a dated MonoTable with WHOOP provenance — on the detail screen and in Investigate — while the trend stays suppressed. Other suppressed specs (skin_temp) keep loading nothing. Co-authored-by: BucciMobile <BucciMobile@users.noreply.github.com>

spo2 is refused on the app side, imported values included. the row and spec were removed on purpose (lib/ui2/README.md, no row and no spec for things we don't produce), so the health/metric_detail half can't go in. the gen5 byte capture is a separate call, if you want it looked at put it in its own pr with the comments cut to a line or two. |

Summary
series: {'spo2': ...}inlib/import/whoop_import.dart, from the export'sblood oxygen %column) but nothing could see: noMetricSpec, no Explore-catalogue row.spo2spec that is suppressed, not charted — same pattern asskin_temp: a chart would mix band-derived and vendor-imported points under one line with no provenance axis, and WHOOP's calibration is not this app's to audit. The StatusCard says whose number it is and why it is not charted..arbfiles.catalogueKeysas a public derived set over the existing_catalogueconst (one source, no second copy).test/spo2_import_surface_test.dart: spec suppressed + signal-free, catalogue row present, importer writes the series row with vendor provenance.Commit 2 — capture the gen5 SpO2 candidate byte, stored unread
The WHOOP 5.0/MG v18 record carries an SpO2 estimate/status byte at
inner[74]every second; the app decoded it and threw it away. This banks it indecoded_onehz.spo2_candidate_rawso the capture exists from now on:Sample.spo2CandidateRaw(raw byte, full reasoning in the field doc) + wired through BOTH decode paths (live drainsampleFromGen5Historical, raw replay indb.dart) + the insert map (omitted-when-null, same form asts_subsec/band_sleep_state)._ensureDecodedOneHzBandFields— existing installs get it on the next open, no schema rung spent.0(the band's own "no sample this second", ~99% of records) preserved verbatim on gen5; null on gen4 — the distinction IS the contract.What this deliberately does NOT change
kSpo2Refusal, onehz_pipeline): within a capture sessionir − redis a fixed offset, so every ratio built from them measures baseline drift, not oxygenation. Neither commit derives anything from raw signals; the second only banks the band's own computed byte.DerivationEngine's own series map still does not listspo2, so a band re-derive can neither fabricate nor blank an imported value (putDayResultreplacesmetric_serieswholesale — one careless null would have wiped every import).kAlgoVersionbump: no analytics output changed; both commits are read-side/storage exposure.Sleep screen & daily metric — explicitly out of scope, with reasons
The sleep screen (
getDaySleepV2) and the daily metric bundle read the REFUSEDb['spo2']ODI block from the 1 Hz pipeline, which staysdisabled: true— that block is the band-raw desaturation path and is permanently refused. Mixing the imported vendor scalar into the night's measured numbers would (a) put a vendor-derived value on a screen whose every other number is measured, and (b) conflate the refused ODI block with a scalar that never was an ODI. The imported value lives where imports live: the Explore catalogue row with provenance in the spec. If owners later want it on the sleep screen, that is a separate, explicit decision — not smuggled in here.Verification
flutter analyze— 3 pre-existing findings only, zero new across both commits.flutter test test/spo2_import_surface_test.dart— 3/3 pass (commit 1).flutter test test/gen5_sample_mapping_test.dart— 20/20 pass (15 existing + 5 new).flutter test test/spo2_candidate_capture_test.dart— 3/3 pass (commit 2, new).analysis_options.yaml,pubspec.lock) reverted — the diff is feature-only.Summary by Sourcery
