Opening any webpage in the remote browser dropped the paired runtime connection, and the client then retried forever without recovering. Causal chain: the screencast travels host->client, a direction that admits up to 8 MiB. The host's encrypted channel rejects anything larger with close code 1013 "Outbound reply buffer overflow" — killing every subscription on that connection. The producer treats a false return as backpressure and retries the identical frame, which for an over-limit frame can never succeed. A permanent condition was being treated as transient. Two changes: 1. A paired-runtime admission wrapper: an over-limit frame is dropped rather than handed to the transport, and reported as handled so the producer advances instead of retrying something doomed. The generic Chromium producer is untouched, so local browser behavior is unchanged. 2. The actual source of over-limit frames. Live frames are hard-bounded by maxWidth/maxHeight, but the navigation snapshot path ignored those bounds entirely, feeding capturePage device pixels straight into the encoder — capturePage's rect is CSS pixels while the bitmap is device pixels, so at deviceScaleFactor 2 a snapshot could be 4x the pixel area the live path is allowed to send. That path fires on page load, which is literally the reported trigger. Applying the caller's own clamp there makes the drop a backstop rather than the mitigation. Dropping a frame is safe here because frames are complete standalone images, not deltas — each replaces the client image wholesale, so the next frame fully repaints. Disclosed in the PR: mobile web-view mode sends no viewport and takes the unclipped screenshot branch, where the drop guard remains the only protection; still strictly better than a 1013 that kills every subscription. Verified by reverting in place: neutralizing the admission guard fails 3 oracles, with the integration test emitting the real [1013, "Outbound reply buffer overflow"] from an actual E2EEChannel — the production symptom, not a mock. Neutralizing the snapshot clamp fails its own oracle, re-proven after the test was relocated. The second half of the report — never recovering without an app restart — is only partly addressed here and is now tracked as STA-3483: the browser stream restart arms a single 500ms retry and never reschedules, so any connection loss can strand the pane. Fixes STA-2970.
