The mobile app loads user profiles to show names, avatars, and agent ownership. Some profiles include a signature that proves who owns the agent. Checking these signatures for a batch of profiles can block interaction because the checks run on the same thread that draws the screen and handles input. This change moves profile batch parsing and signature checks to a background worker. It processes one batch at a time and combines queued profile requests. It keeps the same signature checks, preserves newer profiles that arrive while a batch runs, and discards results after a community change. Individual live profile updates still use synchronous verification. Tests cover newer live updates, community changes, overlapping requests, stale malformed events, and UI timer responsiveness through the production parser. The responsiveness test fails if parsing is moved back to the UI isolate. A regression also exercises a confirmed profile save while an older batch is paused, including preservation of verified ownership. All 38 focused tests, all 2,132 mobile tests, and the analyzer pass. With 500 valid owner signatures, an AOT test reduced the main-isolate timer delay from about 3.4 seconds to less than a millisecond. Total verification time stayed similar. This measures verification work, not overall screen speed. GitHub CI passes. The full local test run failed on two timing-sensitive ACP tests in unchanged Rust code; both passed isolated retries. All other local checks passed, including the downstream tests and builds run after that failure. --------- Signed-off-by: Tom Brow <tomb@block.xyz>
