description	Runtime-verify a renderer change by driving the app in a browser — build/launch/drive recipe for Nova Spektr.

Verifying renderer changes in a real browser

Launch

• pnpm start:renderer serves the renderer at https://localhost:3000 (Vite, ~30s until first page finishes bundling). The full Electron pnpm start is NOT needed for renderer-only changes — the app works in a plain browser.
• The mkcert-style dev cert covers localhost only — https://127.0.0.1:3000 throws a cert interstitial. To get an isolated storage origin (fresh IndexedDB/localStorage without touching existing dev data), start a second instance: pnpm start:renderer --port 3001 — same cert hostname, different origin.
• Dev data (wallets, operations) lives per-origin. localhost:3000 and :3001 may already contain the developer's real dev profiles — treat them as user data: read-only driving is fine, don't import DBs or clear storage, and revert any localStorage flag you flip.

Getting a wallet

• Onboarding page (dev builds) has an Import database button accepting a Dexie export JSON; seeds live in tests/system/data/db/ (e.g. transfers/transfers_tests_db.json). Only do this on a fresh origin.

Driving gotchas

• Browser-extension type actions drop characters in the recipient Combobox — SS58 addresses arrive mangled and fail checksum validation. Set values via the native setter instead: Object.getOwnPropertyDescriptor(HTMLInputElement.prototype,'value').set.call(input, addr); input.dispatchEvent(new Event('input',{bubbles:true}))
• A valid stranger address for Polkadot-family chains: 13mAjFVjFDpfa42k2dLdSnUyrSzK8vAySsoudnxX2EKVtfaq (from the system-test fixtures). Don't type addresses from memory — checksum fails read as "Address has incorrect format".
• Hash-only navigate calls do NOT reload the page — persisted stores (effector-storage persist) only re-hydrate on a real location.reload(). Same-tab localStorage.setItem does not fire storage events either.
• Live model state is inspectable via Vite module URLs: await import('/@fs/<abs-repo-path>/src/renderer/aggregates/<x>/model.ts') then .getState() on stores. knownCount-style sanity values tell you whether you got the app's instance.
• Address-book connection state is driven by localStorage key address-book-has-ever-connected ('true'/absent) — flipping it + reload moves the app between never-connected and disconnected (unverifiable) modes without a backend. Fully-connected mode needs real backend auth; cover it with integration tests instead.
• The operations table needs a wide window; row action buttons (Approve/Reject) may sit off-viewport — use the extension's find for them rather than scrolling blindly.
