A connection allowed without "Remember my choice for this site" lived in a module-level object in the background, so it ended the first time Chrome stopped the idle worker. Each such connection is now one item in the browser's session storage, which outlives the worker and is emptied when the browser closes, read and written through new wrappers in src/shared/browserApi.js. Removal in Settings, address switch, address removal and wallet removal still end it; Settings now waits for the removal before redrawing.
manifest/firefox.json now declares a minimum of Firefox 115.0, the first with session storage.
Judgement call: address and wallet removal still notify the background without waiting.
Model: opus-5-5
Five defects, one of which destroyed every wallet, came from src/background reading and writing the module-level state singleton the MV3 worker never populates, which silently served DEFAULT_STATE. Each point fix created the next defect. The background now has its own per-call getState() and a queued read-modify-write updateState(); the singleton is unreachable from it, and an unpopulated read throws instead of serving defaults.
The prohibition is enforced by the build, not by review: build.js asserts over esbuild's own metafile that no forbidden module is an input of a background bundle, so every specifier syntax esbuild resolves is covered, and both halves of the table are checked for rot -- a stale key, a stale module, an empty list, or an unlisted entry point under src/background/ all fail the build. The ESLint rule remains as fast local feedback and reads the same shared table. Known bounds are documented where the table lives.
Also closes#320: getProvider() now requires a validated network id, so a cold worker no longer prepares a non-mainnet dApp transaction for mainnet and gets refused by the wallet's own verifier. backgroundRefresh() no longer mutates address objects across a network round trip, the broadcast path takes its endpoint and chain id from one snapshot, and eight test storage stubs now structured-clone on get as the real chrome.storage.local does.
closes#320
