Repos gated reads on raw navigator.onLine and the online branch had no try/catch, so a captive portal or connected-but-no-internet (navigator.onLine lying "true") threw a network error instead of serving the good cached copy — blanking the trip even though Dexie held it. - new onlineThenCache(onlineFn, cacheFn) helper: reads the cache when offline, and on a network-level failure (Axios error with no HTTP response). A genuine HTTP error (4xx/5xx — the server responded) is rethrown so callers still set error state / navigate, not masked by a stale cache. - gates only on navigator.onLine, NOT the connectivity probe: the probe is a coarse global flag and one failed health check would otherwise divert every read to the (possibly empty) cache even when the request would succeed. - every repo list/get read path routed through it (reads only — writes still go through the mutation queue so failures surface) - tests: captive-portal fallback, HTTP-error rethrow, non-Axios rethrow
