Review guide: #102-#111 (staging)

[epicexcelsior]

Ten related PRs against staging, split into independent changes. Each was gated before merge: tsc, lint, secret + fake-money scan, tier0 config/services. The merged result is tsc-clean, expo export clean, and gradlew :app:assembleDebug produces a debug APK. Not yet verified: on-device / post-auth behavior.

PR	Area	What changed	Priority
#103	wallet	exists() reads the wallet marker strictly, so a transient Keystore failure can't overwrite a funded wallet.	High — funds
#109	onboarding	New story flow with a WebP hero (replaces the freezing video decoder), no cold-start permission prompts, first-run card instead of an empty-contacts dead end.	High — large surface
#105	nodes / peers	Off-grid screens show stale peers honestly and under-claim reachability instead of implying live reach.	Medium
#106	send	Human-readable failure copy with honest sent / not-sent semantics.	Medium
#111	ui	Beacon stake reads as a roadmap pill, fake file-save button removed, honest SPL disabled copy, fee-estimate retry, resend/discard, spacing tokens.	Medium
#104	messages	Honest send status on every outbound bubble; long-press to copy.	Low
#108	peers	Deterministic identicons across peer rows, sheets, headers, and the mesh map.	Low
#107	nav	Back closes the open thread; tutorial deep link survives hydration; group LEAVE strip hidden.	Low
#102	build	Fixes a staging tsc error, declares two previously-transitive native deps, hardens tier0 scans.	Skim
#110	dev	Dev-menu screen that simulates execute_cosigned_transfer on devnet. __DEV__-only, simulation-only, no keys — cannot run in production.	Skip — dev-only

Notes

• staging matches the combined branch except one intentional change: the unused expo-video plugin was dropped.
• Known follow-ups: remove the now-unused expo-video dependency; legacy SPL send stays disabled pending an on-device error capture.
