Seven overview sections had hand-rolled the same card literal, and the copies
had already drifted on the one thing the literal did not pin: the space
between blocks. Three used 12 px, two 8 px, one 16 px, one under the other in
the same column.
`InsightSectionCard` composes `Card`, so the frame comes from the card
contract, and fixes the inner rhythm at 12 px. The daily briefing moves onto
it as well, and the lab-changes list keeps its edge-to-edge rows through the
documented flush variant.
Visible change on the overview column: two bodies open by 4 px, one tightens
by 4 px, and all of them pick up the shadow their card neighbours already
had. Chart bodies are untouched.
ECG recordings had no pill in the tab strip, no entry in the sub-page
manager, and no routed page — the only inbound pointer was a cross-link
card on the spot-pulse page. Hiding the overview ECG teaser left no route
back to a user's recordings.
- Add a routed `/insights/ecg` sub-page that reuses the existing ECG
section (heading suppressed so the page shell owns the title); the
overview teaser stays.
- Add an ECG entry to the Heart group of the tab strip, gated on a
dedicated `hasEcgRecordings` signal since ECG carries no measurement
type. The Heart group surfaces for an ECG-only device too. No ECG pill
appears without recordings.
- Mount the ECG cross-link on the resting-pulse and HRV pages, matching
its placement on the pulse page.
- List ECG in the sub-page manager under Heart, its eye toggling the ECG
overview section so hiding it is reversible.
- Point the metric catalog's ECG row at the new page.
- Add `navEcg`, the sub-page description, and the empty-state copy across
all locales.
Fold the ECG silo into the insights narrative without crossing the
non-diagnostic line — the app reports the recording device's own verdict
and the existence/count of recordings, never an interpretation of the trace.
- Feature snapshot: a bounded, device-verdict-only ECG descriptor (recording
count, device-verdict distribution, latest recorded-days-ago + average HR)
flows into the nightly briefing prompt. The waveform never enters the
payload; the grounding gate admits the pre-computed counts so a
device-attributed sentence stays grounded. A prompt rule (EN + DE)
constrains any mention to the device's attribution and forbids reading
morphology, measuring intervals, or emitting a verdict of the app's own.
- Pulse cross-link: a device-attributed pointer from the resting-HR / pulse
page into the ECG viewer, un-mounting when no recordings exist.
- Daily rail: an ecg_new_recording item surfaces once when a recording landed
within the last day — calm, info-level, deep-linking the viewer. Gated on
the insights module; the DTO carries no waveform.
- i18n across all six locales; non-diagnostic disclaimer copy per language.
ECG recordings synced from a compatible watch were stored encrypted but
shown nowhere. They now have a surface in Insights: a list of recordings,
each opening the full single-lead waveform on a familiar ECG grid, with the
date, duration, average heart rate, and the result the device recorded.
The read routes narrow ownership in the query and decrypt the waveform
through the existing fail-closed codec; the overview is min/max-decimated so
the R-wave peaks survive the reduction, with a raw path for a calibrated
view. The result shown is the recording device's own classification,
attributed to the device — HealthLog does not read or interpret the trace
and produces no verdict of its own. A permanent note states this, and a
non-normal result carries a line to discuss the recording with a clinician.
