The low-stock alert fired when the projected runway dropped below the
user threshold (default 7 days). For a sparse cadence — a weekly
injection's 7-day floor is barely one dose-interval — the warning landed
with about one dose left, too late to reorder before the supply ran out.
Add an optional per-medication reorder lead time plus a user-level
default (0–60 days, default 10) and widen the alert trigger to
max(lowStockRunwayDays, leadDays + cadenceIntervalDays), so the warning
lands before the last dose for any cadence. Because the trigger is a
max() over the user floor it never shrinks anyone's current threshold; a
daily med with no lead keeps its prior boundary.
The push body and the card notice surface concrete dates — supply runs
out around <date>, reorder by <date> — with a last-dose informational
state and the days/units fallback when supply data is thin. Retire the
stale fixed 4-dose count threshold on the GLP-1 details endpoint and
route its card lowStock flag through the same runway evaluation so the
card and the daily cron agree. Surface the lead default in the low-stock
settings card with progressive disclosure; a single medication can
override it.

- The escalated card row keeps its time anchor: the red badge carries
the matched window or the overdue-slot value beside it, and the
inline row's range stays visible on mobile, where it was the only
clock on the card.
- Take-all-due collects what the cards offer: a dose escalated past its
catch-up band joins the set with exactly the slot the card's own
button would record; as-needed medications never join.
- The table's stock warning follows the user's runway threshold instead
of a leftover four-dose constant; threshold off means no amber, empty
stays red.
- The card itself shows the remaining runway in the warning tone once
it crosses the threshold — only then, the card stays calm above.
- The low-stock push deep-links straight into the supply tab and its
APNs payload keeps url, runwayDays and thresholdDays; supply tab and
threshold setting link to each other; the reminder-thresholds and
notification-prefs endpoints enter the OpenAPI contract.
