iOS fresh signed-out installs present fabricated sessions as real account history

[yxlyx]

Summary

A fresh, signed-out install opens to realistic fabricated session rows without any Demo/Sample label. The rows look like account history, including titles, models, statuses, progress, timestamps, and transcripts.

Users can reasonably interpret this as real or retained account data, especially on a shared/test device.

Simulator reproduction

Confirmed on a fresh iPhone 17 Pro simulator running iOS 26.4:

1. Install the current app with no codegraff key in Keychain.
2. Cold-launch normally.
3. The Sessions screen immediately displays:
   • “Add cube transport to c…” — Working, 2/5, just now
   • “Extend graff serve…” — Waiting on you, 1/3, 2m ago
   • “Notarize v0.0.16 build” — Done, 3/3, 1h ago
4. No visible text identifies these rows as examples or demo content.

Root cause

SessionsListView initializes signed-out state with sampleSessions (apps/ios/Graff/Sources/SessionsListView.swift:4-6). The fixtures in GraffApp.swift:155-180 are realistic and navigable, but SessionsListView/SessionRow provides no user-visible Sample/Demo treatment. This behavior is not gated by --autotest.

Expected behavior

Prefer an explicit signed-out empty state with a sign-in call to action. If examples are intentionally retained:

• isolate them from account history;
• label every example clearly and persistently as Demo/Sample;
• prevent confusion with account-owned sessions and credentials;
• keep full fixtures behind test/demo launch configuration where possible.
