The old service-worker.js (repo root, removed when web/ was rewritten) cached every same-origin GET keyed only by frontend PACKAGE_VERSION, so a backend-only change never invalidated it. Browsers that had visited this origin before the rewrite kept getting stale cached API responses (bootstrap/session calls) served instead of hitting the real backend -- looked like "login succeeds then immediately bounces back to login". Adds a same-path kill-switch service-worker.js that purges all caches and unregisters itself, plus an explicit update() check on app boot so already-registered browsers don't have to wait for the browser's own lazy update schedule.

// Kill switch for the pre-rewrite service worker (formerly at repo root, see git history).
|
|
// That worker cached every same-origin GET (including session/bootstrap API calls) keyed only
|
|
// by frontend PACKAGE_VERSION -- a backend-only change (deploy, migration, cutover) never
|
|
// invalidated it, so browsers that had visited this origin before the rewrite kept getting
|
|
// stale API responses served instead of hitting the new backend, which looked like "login
|
|
// succeeds then immediately bounces back to the login page".
|
|
//
|
|
// This file's only job is to replace that worker in already-registered browsers and remove
|
|
// it entirely: purge its caches, unregister, then reload any open tabs so they load uncontrolled.
|
|
// The rewritten app (web/) does not use a service worker for anything -- do not add fetch
|
|
// caching logic here.
