The reload cleared every HealthLog cache after asking the worker to
update, but the update resolves as soon as the new worker starts
installing. Its fresh precache of logos and favicon was deleted with
the old ones, so the installed app lacked them offline. Leave the
target release's caches in place.
The "new version" Reload action unregistered every service worker before
reloading. Unregistering a registration ends its Web Push subscription
and nothing in the app re-creates one, so each update silently turned
push reminders off in the installed app: the server kept the dead
endpoint and the settings card showed push as off.
Reload now asks the registration to update (the new worker activates at
once and drops the previous release's caches), deletes only HealthLog's
own caches, and reloads. The cache-name contract moves into
sw-cache-policy.ts so the session-end cleanup and the poller share it.
The 60s poller used to unregister service workers, wipe CacheStorage,
and call location.reload() the moment it saw a version bump, with no
prompt — firing mid-form, mid-message, or mid-wizard and discarding
whatever the user had typed. Keep detecting the new build, but now show
a non-blocking, dismissible toast with a Reload action; the eviction and
reload run only when the user chooses to reload. Show the toast once per
detected version.
The update poller and the chunk-error reload guard key on the target
version instead of disarming for the whole session, so a second deploy
re-arms the self-heal and a stale shell can no longer strand with
404ing chunks. Lazy chart imports retry once and mount inside a
per-card error boundary with a reload affordance — a failed chunk
degrades to one card instead of replacing the page. The JSON API
client attaches a fifteen-second timeout unless the caller brings its
own signal (the raw streaming path is exempt), chart queries surface
errors with a retry instead of rendering as an empty period, per-type
fetch failures reject instead of caching an empty series as fresh, and
the session and snapshot queries retry once on transient network or
server errors.
