The bundled WebView build is only compatible from Android 10 (API 29); on Android 9 it lands on
the in-app unsupported-engine screen. Declaring minSdk 29 lets RuStore/Google Play block older
devices at install rather than shipping a known-incompatible build.
Two native offline-first boot glitches (seen on Android 10):
- bootOffline forced offlineNoNetwork, so its first successful reconcile healed to online with a
spurious "back online" toast on a first launch that actually had connectivity. The boot-assumed
offline is now PROVISIONAL: the first probe confirms it — a success heals silently (nothing to
come back from), a failure turns it into a real offline whose later recovery does toast.
- A native launch with a cached guest session (no email) skipped the offline short-circuit and hung
~25 s on adoptSession's retrying profile fetch in airplane mode. The native channel is offline-first,
so it now takes the same reachability-gated fallback (~3 s bound) as an installed email PWA.
Every guest showed a bare "Guest" to opponents (e.g. in a random match). Mint the display name
as "Guest" + a random six-digit suffix at provisioning, so guests are distinguishable. Not an
identifier and not unique — a label only, so collisions are harmless.
A guest host has no meaningful display name to seat, so the offline 'with friends' flow's
"do you take a seat?" prompt only produced a nameless seat. For a guest the prompt is skipped:
after the master PIN, the two empty player seats show directly. A durable host is still asked.
The game header identified the viewer's seat only by app.session.userId, but a device-local
game (vs_ai / hotseat) created offline is seated under the local guest id (the lobby already
matches both). After a merge switched the active account to a durable id, the human seat matched
neither, so a vs_ai game showed BOTH seats as robots (the turn still worked — it is seat-index
based). seatName now matches app.session.userId OR localGuestId, like the lobby. Completes the
v1.22.0 repointLocalGameSeats fix, which only covered games seated under the retired session id.
