The push endpoint host is user-controlled — the browser supplies it at
subscribe time. `isPublicUrl` guards it at subscribe time and again before each
dial, but it is a literal input-time check and cannot see a DNS rebind between
the accept and the connect; with a short-TTL record the dial reaches the pod's
private network.
`web-push`'s `sendNotification` dials with its own internal `https.request`,
which bypassed `safeFetch` and therefore the connect-time pin entirely. Both
senders now sign and encrypt through `generateRequestDetails` — identical VAPID
handling and payload encryption — and dial through `safeFetch` with
`requirePublicHost`. Non-2xx is re-shaped as the `{ statusCode }` rejection the
existing classification already understands, so the 410/404 expiry reap and the
transient/permanent split are unchanged.
This is the last user-controlled-host egress that was not behind the pinned
dispatcher (issue #217).
The MEDICATION_INTAKE_SYNC fan-out used to fire one silent APNs per
distinct dose slot, so a bulk intake marking five doses woke every other
device five times. Replace the per-slot dispatch with a per-user
coalescer: the first mutation in a burst dispatches immediately, every
further mutation inside the 2 s window folds into one trailing fan-out.
A bulk request now costs exactly one queue call, and a rapid burst of N
single-dose mutations costs at most two fan-outs. The window state is
in-process; multiple app instances throttle independently, which is
accepted because the iOS reconcile is idempotent and the deployment
model is a single container.
The silent payload shrinks to a pure sync trigger — eventType +
syncedAt. The per-slot medicationId / scheduledFor fields are gone: the
iOS handler runs a full reconcile regardless, a coalesced burst has no
single slot to name, and a push payload travels through Apple's
infrastructure, so it now carries no health data by construction. The
Live Activity end push likewise sends only the ActivityKit envelope.
The trailing flush keeps the origin skip only when every coalesced
mutation came from the same device; a mixed-origin burst wakes everyone.
Each flush still records one push_attempts ledger row, reaps
hard-rejected device tokens, and annotates the wide event with the
recipient count and coalesced-mutation count.
One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
Self-hosters without an Apple Developer account rely on Web Push to the
installed PWA — there is no Live Activity or lock-screen widget to drive.
Make that path carry the dose lifecycle on its own:
- Stable per-slot tag. The medication dose-due reminder now sets a
`med:<id>:<iso-slot>` Web Push tag (medicationDoseTag), so a re-fired
reminder for the same slot coalesces instead of stacking, and a later
clear can target it.
- Clear-on-taken. When a dose is marked taken or skipped, push a
`type:"clear"` notification reusing that slot tag. The service worker
closes the matching pending reminder and refreshes the badge — the PWA
equivalent of ending a Live Activity. A snooze leaves the dose
outstanding and clears nothing. Wired into the single + bulk intake
routes alongside the existing APNs cross-device sync.
- App badge. The dispatcher carries a server-authoritative outstanding-
dose count; the SW reflects it via the Badging API
(setAppBadge/clearAppBadge), feature-detected and a no-op where
unsupported.
- The SW push handler honours requireInteraction for urgent events and
renotify so a re-fired reminder re-alerts.
Dose-due, preventive-care, and low-stock reminders already cascade to
Web Push when no APNs channel exists; tests pin that an APNs-less
instance still delivers.
